Changes in rainfall patterns spur plant growth, carbon absorption across
U.S.
A NASA-funded study finds that changing rainfall patterns over much of
the United States in the last century have allowed plants to grow more
vigorously and absorb more carbon dioxide from the atmosphere.
In the presence of water and sunlight, plants take in carbon dioxide
(CO2) during photosynthesis to create fuel, glucose and other sugars,
for building plant structures. Better understanding of biological and
physical processes that contribute to carbon uptake by plants will help
scientists predict climate change and future levels of CO2, a
heat-trapping gas in the atmosphere.
"The changes in the hydrologic cycle is one of the mechanisms that is
often overlooked in the recent debate over carbon sequestration in the
United States," said Ramakrishna Nemani, a researcher at the University
of Montana's School of Forestry, and lead author of the study that
appears in an issue of Geophysical Research Letters later this month.
Scientists have noticed that the U.S. terrestrial carbon sink, an effect
where carbon is drained from the air and stored in the land, has been
increasing since the latter part of the 20th century. Previous research
has claimed this rise may be due to an observed greening of the U.S. as
a result of forest re-growth, as well as greater concentrations of
atmospheric CO2 and warming temperatures.
For the first time, however, this study suggests that changing rainfall
patterns may play a bigger role in plant growth and carbon absorption.
Computer model results showed that on average from 1950 to 1993 higher
humidity combined with an eight percent increase in precipitation has
led to a 14 percent increase in plant growth in the U.S. The data over
that time period also show increases in cloud cover, minimum
temperatures, soil moisture and stream flows, which are all signs of a
changing hydrologic cycle.
Whether or not shifting rainfall patterns result in a positive uptake of
carbon by land ecosystems depends on complex interactions that include
plant physiology, and both the magnitude and timing of changes that
impact the water cycle.
Between 1950 and 1993, in general, the minimum temperatures in the
spring have become warmer, and autumns have become wetter, which have
combined to lengthen the growing season for plants. A longer growing
season means plants pull carbon from the air for a greater period of
time. In addition, the magnitude of precipitation on average has gone up
in the conterminous U.S., except over the Pacific Northwest.
"Most people only think of the idea that more water means more growth,
but really plants benefit from more water in a number of ways," said
Steven Running, a co-author of the paper, who is also a researcher at
the University of Montana's School of Forestry.
When the air is wetter, plants can open special cells in their leaves
without losing much water to the air, increasing CO2 uptake while
reducing the amount of water needed to grow. Additionally, wetter soils
promote decomposition of dead plant materials, releasing nutrients
needed for plant growth. Also, higher humidity in the spring helps
maintain higher night temperatures, which makes for more frost-free days
and lengthens the growing season.
The authors found that without enhanced rainfall and humidity, CO2
increases and temperature changes have a lesser effect on plant growth.
Greenhouse gases warm the air, and warmer air can hold more water, which
impacts the hydrologic cycle. Changes in the hydrologic cycle may mean
more rainfall in some regions and less in other places, affecting plant
growth and carbon absorption, which in turn affects future
concentrations of greenhouse gases, Nemani said.

End of 'free ride' on ecosystem CO2 absorption
DURHAM, N.C. -- According to a new study, the world may soon see the end
of the "free ride," in which carbon absorption by natural ecosystems
ameliorates the rise in atmospheric CO2 due to fossil fuel burning and
loss of forest.
The precise ecosystem study of the reaction of a Texas grassland to a
range of carbon dioxide levels has shown that soil nitrogen availability
may limit the capacity of ecosystems to absorb expected increases in
atmospheric CO2. The researchers said their study emphasizes the urgency
with which the U.S. and other nations should adopt stringent limitations
on CO2 emissions, as outlined in the international Kyoto accord on
climate change.
The researchers, led by Duke University ecologist Robert Jackson and
USDA Agricultural Research Service researchers Wayne Polley, and Hyrum
Johnson, published their findings in the May 16, 2002, Nature. First
author of the study is Richard Gill, a former Duke postdoctoral
associate, now a faculty member at Washington State University. The
research was supported by the Department of Energy and the U.S.
Department of Agriculture.
"Based on fossil fuel emissions, the carbon dioxide concentration in the
atmosphere should be going up twice as fast as it currently is," said
Jackson. "However, natural systems such as the regrowing Eastern forests
are currently taking up that extra carbon dioxide, so we're really
getting a free ride now.
"Many of us, myself included, believe that this free ride won't continue
to the same extent that it has, because the incremental benefits of the
extra CO2 get smaller and smaller relative to other nutrient
constraints," he said. The policy implications of their findings are
apparent, said Jackson.
"Considering the expected population increase, greater resource use per
capita and the inability of natural systems to take up CO2, we may well
be looking at increases per year that are double what they are now, with
atmospheric CO2 concentrations as high as 800 parts per million in this
century," he said. "This means that the current lack of interest by the
U.S. in participating in the Kyoto accords is especially unfortunate."
According to Jackson, the study offered a new approach to studying the
ecological effects of increased CO2.
"The study is unique in enabling us to study the effects of CO2
concentrations ranging from those before the Industrial Revolution to
those projected for the next century," said Jackson. "It is also unique
in providing a continuous gradient of CO2 in the field, allowing us to
examine nonlinear and threshold responses and limitations of the system.
Nitrogen availability appears to be one such limitation on the ability
of plants to absorb CO2."
The researchers chose a section of north Texas prairie as the site for
their experimental apparatus, which began operation in May 1997. The
apparatus consists of two 60-meter-long long plastic-covered chambers --
resembling giant segmented worms -- erected over the grassland. The
chambers measured about a meter wide and a meter high.
In one chamber, the scientists expose the grasses to a smooth gradient
of CO2 concentrations ranging, from the current 365 parts per million
(ppm) level down to the 200 ppm present at the end of the last ice age.
The scientists achieve this concentration gradient by blowing ambient
air into one end of the chamber, and as the air flows the length of the
chamber, CO2 uptake by the grasses reduces CO2 concentrations down to
200 ppm.
In the other chamber, the scientists pump into one end air enriched to a
CO2 concentration of 550 ppm -- the expected level over the next
century -- and the plants' CO2 absorption reduces this to 350 ppm at the
opposite end. The chamber also includes controls to ensure that moisture
and temperature levels match those outside.
"There have been few experiments, even in growth chambers, that could
explore the effects of changes since before the Industrial Revolution,
but our design enables us to do just that," said Jackson. "Thus, it
gives us insights into what changes occurred in the past and improves
our understanding about will happen in the future." Operating the
apparatus over multiple growing seasons, the scientists conducted
detailed biochemical and biological analyses of the grass plants as well
as the soil. They also measured how the species composition of the plant
community changed.
"We found that many of the plants' physiological processes responded
fairly linearly to increases in carbon dioxide, and plant production
went up," said Jackson. "However, production and soil carbon storage
basically saturated above 400 parts per million, a CO2 concentration
very close to the current one.
"For me, this was the most interesting part of the study, because it
indicates that we are now right at a threshold where the benefits of
extra CO2 may not be all that great." Particularly important, said
Jackson, were the measures of soil nitrogen availability. Soil bacteria
metabolize organic matter, mobilizing nitrogen as ammonia and nitrate,
which serves as the plants' nitrogen nutrient source
"Our measurements showed that soil nitrogen decreased about threefold in
a nonlinear way, such that as CO2 went up, available nitrogen went
down," said Jackson. "So that's where the fundamental nutrient
limitation of the system occurred. The decrease in nitrogen availability
apparently constrains the ability of the plants to use extra CO2. "
According to Jackson, the findings by him and his colleagues agree with
tentative findings by the Forest-Atmosphere Carbon Transfer Storage
(FACTS-1) facility at Duke (http://www.env.duke.edu/forest/FACTSI.htm).
In that facility, sections of open forest are maintained at high CO2
levels, to study their effects. Data from a prototype FACTS-1 facility
indicated that the forest section under study had stopped responding to
high CO2 levels with enhanced growth.
The researchers plan future studies using the apparatus to examine
another potential limitation, water availability, said Jackson.

Thanks for the people sending sugestions about my question on "how to
measure canopy cover". The suggestions are to use densiometers or
densitometers. Both instruments are available at:
http://www.forestry-suppliers.com
But.... I have another question.
What do you people think about using a simple grid (50x50cm) with 100 cells
and to count the number of cells covered by vegetation or ... simply to
count the number of cells with or without vegetation? This grid is used to
measure herbaceous coverage and is simple and cheap!

Paleoclimatic and paleoecological analysis of Holocene Sediments
1413 - Reston, VA
Sponsored by US Geological Survey
Description:
Paleoclimatic and paleoecological analysis of Holocen sediments
using micropaleontology, geochemistry and sedimentology from the eastern
United States, including Chesapeake Bay and other mid-Atlantic estuaries,
are the focal points of this project. Estuarine ecosystems of the 3eastern
United States have undergone numerous human disturbances, resulting in
altered faunal distributios and varying rates of sediment influx into
estuaries. Understanding the roles of natural and man-made stresses in
controlling changes in faunal distribution and understanding the impact of
sedimentation are fundamental requriements for proper management of natural
resources of the region. This project is designed to document historical
changes in the ecosystems and sedimentation, to establish baseling levels of
natural exosystem variability, to examine land-use changes and their impact
on sedimentation, and to document impacts of Holocene climae variability on
ecosystems. Analyses focus on sediment core records including faunal and
geochemical evidence from estuarine and marine microfossils.
Objectives of internship:
The intern will function as a physical science technician providing
support to a research scientist in data collection, processing, and
analysis. Independent creativity and development within these functions is

Specific Tasks:
1. Laboratory Work: Sampling and processing for foraminifera and
ostracodes.
2. Field work: collection of sediment short cores and living
populations.
3. Database entry and data manipulation, including graphic
representation of data and results.
Work experience to benefit to intern:
The project will provide the intern an opportunity to gain
experience in estuarine environments and a variety of laboratory techniques,
broaden the intern's knowledge and understanding of ecosystem habitats,
climate change and provide an opportunity for expanded computer
capabilities.
Qualifications:
Requirements:
At least 2 or 3 years towards a Bachelor's degree in geology,
biology, or environmental science. Knowledge of Macintosh applications,
figure preparation and report writing.

Quantitative Analysis of National Stream Restoration Efforts
Funding is anticipated for a postdoctoral research associate position
for advanced quantitative research associated with the synthesis of
stream restoration projects throughout the U.S. The position is for 3
years (contingent on continued funding), beginning in the fall of 2002.
The candidate will work under the guidance of Drs. Margaret Palmer and
David Allan. The candidate will be in residence at the University of
Maryland but will work closely with American Rivers and with a team of
researchers throughout the country (C. Dahm, S. Gloss, P. Goodwin, D.
Hart, M. Kondolf, J. Meyer, J. Stanford). The successful candidate is
expected to have a background in running-water ecosystems with strong
statistical and computing skills. Excellent written and verbal

Subject: How to calculate a truncated Poisson distribution?
Dear Sir or Madam,
I am looking for information on how to analyze a certain data set using
truncated Poisson distributions. The table that I include below presents
information on the frequency of individuals of certain snake species that
contained 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 and 35 prey. One of the
referees of the manuscript suggested that I should analyze these data using
a truncated Poisson distribution to determine whether there is a non-random
tendency for 2, 3, 4 or whatever number of prey to occur (the dominance of
single prey notwithstanding). Sokal and Rohlf's Biometry text indicate
that Cohen (1960. Estimating the parameter in a conditional Poisson
distribution. Biometrics 16:203-211) gives instructions on how to calculate
truncated Poisson distributions. Despite numerous attempts and long hours,
I just cannot understand how I can use Cohen's paper to generate a
truncated Poisson distribution to compare my data with (I acknowledge that
I am mathematically challenged). I have also consulted more recent papers
published in statistical journals (Biometrics, Statistics and Medicine) but
those articles are too technical for me. Thus, I was wondering whether
someone would be willing to assist me, or at least point me in the right
direction. For example, are there any articles or textbooks aimed at
non-statisticians that give detailed instructions on how to conduct this
procedure? Any help you may want to give me is GREATLY appreciated!
Sincerely,

Subject: Biologists hook Atlantic salmon in river near Cordova, Alaska
http://www.adn.com/front/story/1075522p-1181797c.html
INVADER: Fish likely escaped from Washington or British Columbia farm.
By Wesley Loy
Anchorage Daily News
(Published: May 10, 2002)
Government fish biologists working near the Copper River Delta say they've
found the first genetically verified Atlantic salmon swimming in fresh water
in that area.
Most likely, the fish was an escapee from a commercial salmon farm in
British Columbia or Washington state. Alaska officials consider these farmed
fish an invasive species and warn that Atlantic salmon, favored for farming
because of their superior growth and survival rates, could someday displace
native Pacific salmon species.

Subject: International biological research
I am a recent graduate of UC Berkeley in search
of international research experience. Currently,
I am in my 5th year as a field/lab assistant.
Most of my work thus far has focused on questions
related to evolutionary ecology and population
biology/genetics.
My goal is to broaden my Biological horizon
before entering graduate school by studying
different types of organisms in a diverse array
of habitats. If all goes well I would like to
set up a series of short-term assistant positions
along the path of a round the world flight
ticket. I can provide the service of a hard
working, interested, and committed field
assistant. In return I would only ask that one
would be willing to share their research
experience with me and that my living expenses be
paid for during the duration of my stay (room and
board), although any extra assistance getting me
there would be much appreciated.
In the past I have worked on various projects
including research of herbivory by rodents and
insects, pollination biology across landscapes,
ectoparasites of small mammals, salamander
reproductive biology, seed dormancy, invasive
plants, plant demography across space and through
time, induced defense in plants, QTL mapping in
Arabidopsis, microsatellite marker establishment,
vegetation surveys, social insect rearing, and
probably a couple other things I can't think of
right now. I have spent a great deal of time in
both the field and the lab, working in groups as
well as independently, and I enjoy research in
pretty much any climatic condition. No location
is too remote and I have a fair deal of
experience getting around in third world nations.
If anyone has any suggestions I would very much
appreciate your advice.
Thanks,
David Lowry

ILLEGAL LOGGING THREATENS ECOLOGICAL AND ECONOMIC STABILITY
Janet Larsen
Extensive floods in Indonesia during early 2002 have killed hundreds of
people, destroyed thousands of homes, damaged thousands of hectares of rice
paddy fields, and inundated Indonesian insurance companies with
flood-related claims. Rampant deforestation, much of it from illegal
logging, has destroyed forests that stabilize soils and regulate river flow,
causing record floods and landslides.
In just 50 years, Indonesia's total forest cover fell from 162 million
hectares to 98 million. Roads and development fragment over half of the
remaining forests. More than 16 million people depend on fresh water from
Indonesia's 15 largest watersheds, which between 1985 and 1997 lost at least
20 percent of their forest cover. Loggers have cleared almost all the
biologically diverse lowland tropical forests off Sulawesi, and if current
trends continue, such forests will be gone from Sumatra in 2005 and
Kalimantan by 2010.
Domestic wood supply in Indonesia was documented at 20 million cubic meters
in 2000, while demand stood at some 60 million cubic meters. Thus legal
supplies of wood fiber fall short of demand by up to 40 million cubic meters
per year. Illegal logging fills the gap--accounting for almost 70 percent of
wood supply. All told, illegal logging alone has destroyed 10 million
hectares of Indonesia's rich forests, an area the size of Virginia in the
United States.
Indonesia's situation is not unique. The Philippines once held 16 million
hectares of forests but is now down to less than 700,000 hectares. In this
country where illegal logging runs rampant, forest loss from tree felling
and conversion to agriculture is cited as the cause of flooding, acute water
shortages, rapid soil erosion, river siltation, and mudslides that have
taken lives, destroyed properties, and wreaked environmental damage.
In 1989, Thailand banned the logging of natural forests in direct response
to devastating floods and landslides that had taken 400 lives the year
before. Though illegal logging is now at lower levels than before the ban,
it is still widespread. More recently, massive flooding of China's Yangtze
River in 1998, which was linked to the removal of 85 percent of the upper
river basin's original tree cover, propelled China to issue a ban on logging
in the upper reaches of the Yangtze and Yellow Rivers and to begin a
reforestation campaign.
China consumes nearly 280 million cubic meters of timber a year, but
domestic supply currently provides only 142 million cubic meters. As
production shrinks, China is turning to imports and illegal logging to make
up for the shortfall. The International Tropical Timber Organization
forecasts that within the next few years China will become the world's
largest log importer, edging out the United States and eclipsing Japan,
whose massive imports have already destroyed many of the rainforests of the
Philippines and much of Borneo.
Fifty-seven percent of the logs brought into China originate in Russia,
where poor law enforcement, corruption, and the abandonment of local
timber-processing plants have led people to illegally cut trees for
companies that send raw materials to China for processing. At least
one-fifth of Russia's timber harvest is taken illegally or drastically
violates existing legislation.
To China's south, Burma (Myanmar) holds about half of mainland Southeast
Asia's forests. These contain a variety of tropical hardwood species that
are increasingly drawing interest from China. On paper, Burma supplies less
than 10 percent of China's log imports, but industry workers say the numbers
must be at least twice as high. Burmese log exports to China are growing
much faster than the trees, many of which are hundreds of years old, can be
replaced. In 1949, tropical forests covered 21 percent of the country's land
area, but now less than 7 percent of Burma is forested.
In Laos, where the volume of illegal logging is the equivalent of at least
one sixth of the legal harvest, the army openly cuts forests. Now less than
40 percent of the country is forested, down from 70 percent in 1940. In
Cambodia, over 70 percent of the timber export volume consists of unreported
logs. And Viet Nam could lose all substantial forest cover by 2020 if the
current rate of deforestation continues.
As the growing Asian timber market has exhausted supplies over much of the
continent, wood imports to Asia from Africa have steadily increased. From
1993 to 1999, Europe imported 40 percent of central African logs, but since
1996, rising demand from Asia has made that region the number one importer
of African timber.
Forest products are the second largest export for both Cameroon and Gabon,
generating about 20 percent and 13 percent of respective export revenues.
Between 1990 and 1995, the share of Cameroonian logs going to Asia soared
from 7 percent to 50 percent. Unfortunately, only half the logging companies
in Cameroon are licensed, and among these companies, violations such as
felling trees smaller than the legal size and cutting outside concession
boundaries are common.
These examples cover only a portion of the global timber market.
Uncontrolled deforestation abounds in other countries--in Brazil, with the
world's highest deforestation rate, where an estimated 80 percent of logging
is illegal; in Mexico, which is losing over 1 million hectares each year;
and in Ethiopia, where in just 40 years forest cover has plummeted from
around 40 million hectares to 2.7 million, only half of which is natural
forest. Rarely, though, is deforestation purely a local issue.
The world's eight largest industrial countries plus the rest of the European
Union buy 280 million cubic meters of timber and timber products from abroad
each year, accounting for 74 percent of the world's timber imports. Most of
this wood comes from countries where illegal tree felling is the norm. In
2000, the United States alone imported over $450 million worth of timber
from Indonesia, which given Indonesia's illegal logging rate could represent
$330 million worth of timber from illegal sources.
If importing countries insist that timber and timber products are certified
under internationally recognized environmental and social standards like
those of the Forest Stewardship Council, illegal logging becomes more
difficult. Exporting countries would profit by protecting the integrity of
forest ecosystems, and could secure higher prices for certified wood on
international markets. Russia, for instance, which loses $1 billion in
export revenues each year because its wood is not certified, is now
developing a mandatory certification system for standing forests.
Certification along with existing international agreements, such as the
Convention on International Trade in Endangered Species of Wild Fauna and
Flora, can help to prevent illegal logs from crossing international
borders--if laws and standards are upheld.
Recycling and reduced use of throwaway timber products can lower the demand
for timber that has made illegal logging profitable. As the Chinese
government has recognized, the services that forests provide, such as flood
control, can be worth far more than the lumber they contain.

Changes in rainfall patterns spur plant growth, carbon absorption across
U.S.
A NASA-funded study finds that changing rainfall patterns over much of
the United States in the last century have allowed plants to grow more
vigorously and absorb more carbon dioxide from the atmosphere.
In the presence of water and sunlight, plants take in carbon dioxide
(CO2) during photosynthesis to create fuel, glucose and other sugars,
for building plant structures. Better understanding of biological and
physical processes that contribute to carbon uptake by plants will help
scientists predict climate change and future levels of CO2, a
heat-trapping gas in the atmosphere.
"The changes in the hydrologic cycle is one of the mechanisms that is
often overlooked in the recent debate over carbon sequestration in the
United States," said Ramakrishna Nemani, a researcher at the University
of Montana's School of Forestry, and lead author of the study that
appears in an issue of Geophysical Research Letters later this month.
Scientists have noticed that the U.S. terrestrial carbon sink, an effect
where carbon is drained from the air and stored in the land, has been
increasing since the latter part of the 20th century. Previous research
has claimed this rise may be due to an observed greening of the U.S. as
a result of forest re-growth, as well as greater concentrations of
atmospheric CO2 and warming temperatures.
For the first time, however, this study suggests that changing rainfall
patterns may play a bigger role in plant growth and carbon absorption.
Computer model results showed that on average from 1950 to 1993 higher
humidity combined with an eight percent increase in precipitation has
led to a 14 percent increase in plant growth in the U.S. The data over
that time period also show increases in cloud cover, minimum
temperatures, soil moisture and stream flows, which are all signs of a
changing hydrologic cycle.
Whether or not shifting rainfall patterns result in a positive uptake of
carbon by land ecosystems depends on complex interactions that include
plant physiology, and both the magnitude and timing of changes that
impact the water cycle.
Between 1950 and 1993, in general, the minimum temperatures in the
spring have become warmer, and autumns have become wetter, which have
combined to lengthen the growing season for plants. A longer growing
season means plants pull carbon from the air for a greater period of
time. In addition, the magnitude of precipitation on average has gone up
in the conterminous U.S., except over the Pacific Northwest.
"Most people only think of the idea that more water means more growth,
but really plants benefit from more water in a number of ways," said
Steven Running, a co-author of the paper, who is also a researcher at
the University of Montana's School of Forestry.
When the air is wetter, plants can open special cells in their leaves
without losing much water to the air, increasing CO2 uptake while
reducing the amount of water needed to grow. Additionally, wetter soils
promote decomposition of dead plant materials, releasing nutrients
needed for plant growth. Also, higher humidity in the spring helps
maintain higher night temperatures, which makes for more frost-free days
and lengthens the growing season.
The authors found that without enhanced rainfall and humidity, CO2
increases and temperature changes have a lesser effect on plant growth.
Greenhouse gases warm the air, and warmer air can hold more water, which
impacts the hydrologic cycle. Changes in the hydrologic cycle may mean
more rainfall in some regions and less in other places, affecting plant
growth and carbon absorption, which in turn affects future
concentrations of greenhouse gases, Nemani said.

End of 'free ride' on ecosystem CO2 absorption
DURHAM, N.C. -- According to a new study, the world may soon see the end
of the "free ride," in which carbon absorption by natural ecosystems
ameliorates the rise in atmospheric CO2 due to fossil fuel burning and
loss of forest.
The precise ecosystem study of the reaction of a Texas grassland to a
range of carbon dioxide levels has shown that soil nitrogen availability
may limit the capacity of ecosystems to absorb expected increases in
atmospheric CO2. The researchers said their study emphasizes the urgency
with which the U.S. and other nations should adopt stringent limitations
on CO2 emissions, as outlined in the international Kyoto accord on
climate change.
The researchers, led by Duke University ecologist Robert Jackson and
USDA Agricultural Research Service researchers Wayne Polley, and Hyrum
Johnson, published their findings in the May 16, 2002, Nature. First
author of the study is Richard Gill, a former Duke postdoctoral
associate, now a faculty member at Washington State University. The
research was supported by the Department of Energy and the U.S.
Department of Agriculture.
"Based on fossil fuel emissions, the carbon dioxide concentration in the
atmosphere should be going up twice as fast as it currently is," said
Jackson. "However, natural systems such as the regrowing Eastern forests
are currently taking up that extra carbon dioxide, so we're really
getting a free ride now.
"Many of us, myself included, believe that this free ride won't continue
to the same extent that it has, because the incremental benefits of the
extra CO2 get smaller and smaller relative to other nutrient
constraints," he said. The policy implications of their findings are
apparent, said Jackson.
"Considering the expected population increase, greater resource use per
capita and the inability of natural systems to take up CO2, we may well
be looking at increases per year that are double what they are now, with
atmospheric CO2 concentrations as high as 800 parts per million in this
century," he said. "This means that the current lack of interest by the
U.S. in participating in the Kyoto accords is especially unfortunate."
According to Jackson, the study offered a new approach to studying the
ecological effects of increased CO2.
"The study is unique in enabling us to study the effects of CO2
concentrations ranging from those before the Industrial Revolution to
those projected for the next century," said Jackson. "It is also unique
in providing a continuous gradient of CO2 in the field, allowing us to
examine nonlinear and threshold responses and limitations of the system.
Nitrogen availability appears to be one such limitation on the ability
of plants to absorb CO2."
The researchers chose a section of north Texas prairie as the site for
their experimental apparatus, which began operation in May 1997. The
apparatus consists of two 60-meter-long long plastic-covered chambers --
resembling giant segmented worms -- erected over the grassland. The
chambers measured about a meter wide and a meter high.
In one chamber, the scientists expose the grasses to a smooth gradient
of CO2 concentrations ranging, from the current 365 parts per million
(ppm) level down to the 200 ppm present at the end of the last ice age.
The scientists achieve this concentration gradient by blowing ambient
air into one end of the chamber, and as the air flows the length of the
chamber, CO2 uptake by the grasses reduces CO2 concentrations down to
200 ppm.
In the other chamber, the scientists pump into one end air enriched to a
CO2 concentration of 550 ppm -- the expected level over the next
century -- and the plants' CO2 absorption reduces this to 350 ppm at the
opposite end. The chamber also includes controls to ensure that moisture
and temperature levels match those outside.
"There have been few experiments, even in growth chambers, that could
explore the effects of changes since before the Industrial Revolution,
but our design enables us to do just that," said Jackson. "Thus, it
gives us insights into what changes occurred in the past and improves
our understanding about will happen in the future." Operating the
apparatus over multiple growing seasons, the scientists conducted
detailed biochemical and biological analyses of the grass plants as well
as the soil. They also measured how the species composition of the plant
community changed.
"We found that many of the plants' physiological processes responded
fairly linearly to increases in carbon dioxide, and plant production
went up," said Jackson. "However, production and soil carbon storage
basically saturated above 400 parts per million, a CO2 concentration
very close to the current one.
"For me, this was the most interesting part of the study, because it
indicates that we are now right at a threshold where the benefits of
extra CO2 may not be all that great." Particularly important, said
Jackson, were the measures of soil nitrogen availability. Soil bacteria
metabolize organic matter, mobilizing nitrogen as ammonia and nitrate,
which serves as the plants' nitrogen nutrient source
"Our measurements showed that soil nitrogen decreased about threefold in
a nonlinear way, such that as CO2 went up, available nitrogen went
down," said Jackson. "So that's where the fundamental nutrient
limitation of the system occurred. The decrease in nitrogen availability
apparently constrains the ability of the plants to use extra CO2. "
According to Jackson, the findings by him and his colleagues agree with
tentative findings by the Forest-Atmosphere Carbon Transfer Storage
(FACTS-1) facility at Duke (http://www.env.duke.edu/forest/FACTSI.htm).
In that facility, sections of open forest are maintained at high CO2
levels, to study their effects. Data from a prototype FACTS-1 facility
indicated that the forest section under study had stopped responding to
high CO2 levels with enhanced growth.
The researchers plan future studies using the apparatus to examine
another potential limitation, water availability, said Jackson.

Subject: Canopy cover II
Thanks for the people sending sugestions about my question on "how to
measure canopy cover". The suggestions are to use densiometers or
densitometers. Both instruments are available at:
http://www.forestry-suppliers.com
But.... I have another question.
What do you people think about using a simple grid (50x50cm) with 100 cells
and to count the number of cells covered by vegetation or ... simply to
count the number of cells with or without vegetation? This grid is used to
measure herbaceous coverage and is simple and cheap!
Thanks again.....

The California Native Plant Society is an Equal Opportunity Employer M/F
Western Riverside Co. Vegetation Project background:
The Western Riverside County, CA, Multi-Species Habitat Conservation
Program (MSHCP) is the largest MSHCP ever attempted. It is an integral
piece of the network of Southern California Habitat Conservation Plans and
Natural Community Conservation Planning. The goal of the plan is to
provide for the conservation of approximately 510,000 acres of land from
the total of 1.2 million acres. The plan^Òs success is critical to
conservation of habitat and species in this rapidly urbanizing part of
California.
Vegetation and habitat inventory is critical to the long-range management
and success of the MSHCP. The purpose of this project will be to establish
a complete vegetation and habitat classification system and field-
monitoring database for the core area of 510,000 acres. The classification
and database will be used to map and monitor the vegetation and habitat of
this area over time to ensure habitat quality and drive management
decisions within the conserved landscape. CNPS will be working in
collaboration with the Department of Fish and Game on this project to
ensure quality data collection, analysis, and interpretation.
A secondary task of this project will be to conduct field assessments of
the vegetation and habitat of the San Dieguito River Watershed, in San
Diego County. An 80,000-acre conservation area within this watershed is in
active planning stages via local, regional and state government and private
NGO^Òs. The plan is for a coordinated conservation corridor running from
central coastal San Diego County to the interior desert of the county.
The field assessment of habitat and vegetation will be used to map,
monitor, and assist with appropriate selection and management of the 80,000-
core area of conservation lands within the watershed. The information
collected in San Diego study area will provide supportive and comparative
information for the analysis of data collected in Riverside County.
California Native Plant Society background:
The California Native Plant Society, founded in 1965, is a statewide non-
profit conservation organization of some 10,000 members and volunteers.
The mission of CNPS is to increase understanding and appreciation of
California^Òs native plants and to conserve them and their natural habitats,
through scientific study, education, advocacy, horticulture and land
stewardship. CNPS has been the state leader in developing protocols for
vegetation sampling, now widely used by many agencies and organizations.
CNPS has parallel goals of habitat conservation through science-based
inventory.
The State Vegetation Program of CNPS has been dedicated to developing and
maintaining information resources about California native plants, natural
plant communities, and ecosystems. The Program is developing quantifiable
definitions of all types of vegetation in California to promote science-
based conservation at the level of the natural community and ecosystem.
The Program views vegetation as the best single expression of the range of
ecological variation, which can be depicted in maps across any landscape
and can be described with standard analytical vegetation descriptions.
CNPS is maintaining a uniform system of vegetation sampling protocols and
vegetation classification. The vegetation sampling protocols have been
developed over the past ten years by the CNPS Vegetation Committee, and
include the CNPS Vegetation Rapid Assessment Protocol and the CNPS Relevé
method (see CNPS web site: www.cnps.org for complete methodologies and
field forms). CNPS staff and members are the primary developers and
expert instructors of the methodologies, which have been adopted by various
federal, state, and private resource agencies that have jurisdiction over
land management, including the CDFG Monitoring and Assessment Program.
Further, CNPS has published A Manual of California Vegetation that provides
a unified vegetation classification with standard language for land
planners and managers to make scientifically informed decisions.

Subject: habitat guidelines
Greetings!
I^Òm looking for examples of well-intentioned but misguided attempts of stat
or federal agencies to formulate habitat guidelines for threatened or
endangered species. For example, the 1985 Recovery Plan for the red-cockade
woodpecker included habitat guidelines that had little or no relationship to
habitat selection or fitness. Do you know of any other cases where
guidelines (esp descriptions of ^Ñgood^Ò quality habitat) were later shown t
be
bogus? If so, were there any biological ramifications of these errors, i.e.
population declines, etc..
Any thoughts or insights would be greatly appreciated.
Many thanks,

Subject: LOWESS summary & GLM question
Dear Ecologgers,
1) LOWESS summary
Some time ago, I posted to the list a question about
available (and preferably free) software to perform a
locally weigthed regression. Below you can find a
summary of the answers I have received.
* R was cited in 3 answers. It is free and can be
downloaded from http://www.r-project.org/
* MINITAB was cited in 2 answers. It is not free, but
it seems that a demo that allows a trial period is
available at http://www.minitab.com/
* Sigmaplot, MatLab and SAS (Proc Loess) were each
mentioned once. They are not free, but they are widely
available, I think. It seems that MatLab is the
cheaper one.
* Other software free and cited once was ADE4,
available at
http://www.statistics.com/content/freesoft/abc/ade.html
*Fortran code to compute lowess regresion can be
downloaded at
http://netlib.bell-labs.com/netlib/go/lowess.f.gz
Finally, I opted for R. It is no very user-friendly,
but in the website there is a lot of good learning
docs, which I have found very useful. In a few days I
have got my lowess regresion and discovered a very
interesting software.
2)GLM question
The next step I am thinking about is learning
something about Generalized Linear Models. I have the
following software available: SPSS, Statistica,
Genstats, GLIM and, now, R. I also know the Crawley
book about GLIM. I would greatly appreciate receiving
advice about software, books or refs that allow me to
begin with GLM's in ecology.
Many thanks,

Hello all,
I am looking for people doing red-tailed hawk research in the western USA.
Specifically I'd like to find people doing wintering or breeding projects
involving getting birds in the hand or banding nestlings. I'm doing a
masters project mostly on migrating red-tails connecting them to their

Position Announcement for a Postdoctoral Research Associate
Quantitative Fisheries Ecologist/Population Modeler
Vermont Cooperative Fish and Wildlife Research Unit
School of Natural Resources
University of Vermont
PROJECT
The Batten Kill was historically the premier trout fishing river in the
Northeast United States. However, in recent years there have been dramatic
declines in brown trout and, to a lesser degree, brook trout populations in
the Batten Kill. In this study, we will determine where the bottlenecks in
recruitment to the fishery are occurring through using historical datasets
of Vermont Fish and Wildlife (1984-2001) and other agencies. Understanding
how individual growth and survival affects different life stages of trout
has the potential to direct mitigative actions to the appropriate limiting
resource(s), which will aid in restoration. To address large-scale effects
(e.g., climate), data from the Batten Kill will be compared to those of two
reference systems that have not suffered similar declines.
STUDY TEAM
The Postdoctoral Associate will coordinate work on data sets with Batten
Kill Team members from the U.S. Forest Service and Vermont Department of
Fish and Wildlife. He/she will work collaboratively with the principal
investigator and the Batten Kill Team on all aspects of analysis, modeling,
and interpretation.
POSITION DESCRIPTION AND REQUIREMENTS
A PhD is required. Applicants should have a strong background in
quantitative fisheries ecology and population modeling. Excellent writing
and communication skills are essential. Ability to work collaboratively
with researchers and managers is required.
The position will be available in late summer or early fall 2002. Earlier
or later start dates are negotiable. Salary is $30,000 plus
benefits. Time period is one year with the potential for additional
funding, if renewed.
APPLICATION PROCESS
Applicants should send a CV, cover letter including their research
interests, academic/professional background, and the names and contact

Maybe I'm being paranoid, but I would appreciate knowing the motivation for
this request. This could be construed as a search for anecdotes to refute
the validity of some specific habitat guidelines, or habitat guidelines in

Subject: motives - habitat guidelines!
Greetings,
Several people have responded to my original request for information on
habitat guidelines with skepticism about the motivation for the request. I
understand the concern, as there are lots of folks out to discredit these
plans and make a buck (at the expense of threatened species). I have no su
h
intentions. Rather, as part of my MS, I am using habitat selection and
demographic data to validate the new guidelines for the red-cockaded
woodpecker. In large part, I have found that the revised guidelines are
appropriate for my study population. If they were not appropriate, perhaps
that would be even more important to know! My original request for
information was based on the need for background information for the
introduction and/or discussion sections of my thesis.
Thanks to all of those that responded and those who didn^Òt (because they ha
concerns about my motives).
Original post below. Comments still appreciated. And yes, I would love to
hear about ^Ñsuccess stories^Ò too.
I know there are many of them.

endangered species. For example, the 1985 Recovery Plan for the red-cockaded
woodpecker included habitat guidelines that had little or no relationship to
habitat selection or fitness. Do you know of any other cases where
guidelines (esp descriptions of ^Ñgood^Ò quality habitat) were later shown t
be
bogus? If so, were there any biological ramifications of these errors, i.e.
population declines, etc..
Any thoughts or insights would be greatly appreciated.

Well if you are paranoid, color me naive. My question is this: if it were
a landowner, or someone wishing to challenge guidelines, does this mean that
you would not provide information? In turn does this mean that we bury the
things that didn't work in the past to prevent their use by people who might
be opposed to our ideas? just wondering...

Maybe I'm being paranoid, but I would appreciate knowing the motivation
for
this request. This could be construed as a search for anecdotes to
refute
the validity of some specific habitat guidelines, or habitat guidelines
in
general, perhaps to the benefit of someone who might be limited by these
guidelines (e.g., a landowner or resource extraction firm).

EPA Posts First Figures on Dioxin Releases in Environment
By ELIZABETH SHOGREN, TIMES STAFF WRITER
WASHINGTON -- For the first time, the Environmental Protection Agency on
Thursday included dioxins--industrial byproducts that cause cancer and
other health problems--in its annual list of the toxins released by
companies.
Self-reported data from 23,000 facilities across the country showed that
220 pounds of dioxins were released into the air and water in 2000.
While tiny compared with the hundreds of millions of pounds of other
pollutants discharged into the environment each year, this amount is
alarming to public health advocates because dioxins are highly toxic in
minuscule quantities. And unlike many chemicals, they accumulate inside
the body, where they can build to dangerous levels.
The so-called toxics release inventory, posted on the EPA Web site, lets
individuals find out whether nearby industrial facilities are releasing
dangerous chemicals.

Subject: House Science Committee Passes Bill to Double NSF Budget
House Science Committee Passes Bill to Double NSF Budget
On May 22, 2002, the House Science Committee passed legislation that
authorizes a 15 percent increase in the budget for the National Science
Foundation (NSF) in each of the next three years. The legislation would
authorize an increase in NSF^Òs budget from $4.8 billion in FY 2002 to
$7.3 billion in FY 2005. The bill would put NSF on track to double its
budget in five years.
The initiative to double the budget of the National Science Foundation
follows a successful effort to double the budget of the National
Institutes of Health (NIH) over five years. According to Rep. Lamar
Smith (R-TX), "The NIH budget has increased to a point where it is now
larger than that of the rest of the science agencies put together. And
the proposed increase alone in NIH funding is larger than the [total]
research budget of the National Science Foundation." Congress remains
highly supportive of NIH, but there is growing concern that funding for
complementary work of NSF has fallen "dangerously out of balance,"
according to a forthcoming letter signed by more than 120 members of
Congress.
When the NSF authorization act was introduced on May 7, the bill
included language about the allocation of funding among "the physical
sciences, mathematics, and engineering." References to "physical
sciences" as opposed to other fields of science could have negative
consequences for the environmental sciences, geosciences, non-biomedical
life sciences, social sciences and interdisciplinary science. NCSE
staff worked with other scientific organizations and Congressional staff
to craft an amendment that replaces "physical sciences" with "sciences"
and makes related revisions. The House Science Committee passed the
amendment to the NSF authorization bill on May 22.
The NSF authorization bill, which is entitled "Investing in America^Òs
Future Act of 2002" (H.R. 4664), has strong bipartisan support in the
House of Representatives. The bill is co-sponsored by 23 members of
Congress, including 12 Republicans and 11 Democrats. The co-sponsors
include Reps. Sherwood Boehlert (R-NY) and Ralph Hall (D-TX), Chairman
and Ranking Minority Member of the House Science Committee, as well as
Reps. Nick Smith (R-MI) and Eddie Bernice Johnson (D-TX), Chairman and
Ranking Minority Member of the House Science Subcommittee on Research.
Legislation to reauthorize the National Science Foundation has not been
introduced in the Senate. On May 22, the Senate Subcommittee on
Science, Technology and Space convened a hearing on the National Science
Foundation. Senator Ron Wyden (D-OR), Chairman of the Subcommittee,
went on record in full support of doubling the NSF budget in five
years. Newt Gingrich, former Speaker of the House of Representatives,
testified that the NSF budget should be increased to $15 billion, more
than triple its current funding level. John Podesta, former Chief of
Staff to President Clinton, testified in support of doubling the NSF
budget.

Having been bit by this particular snake, I guess I would at least ask the
question: For what purpose is this information being requested? Then I
would provide whatever facts (not ideas) I could that are based on my
personal and professional experience, pointing out (and providing facts on)
the preponderance of successes over mistakes.
