Scientists: Collapse of coastal ecosystems tied to past overfishing
GAINESVILLE, Fla. --- Dying coral reefs, dwindling shellfish
populations, shrinking seagrass beds and other collapses of the world's
coastal ecosystems are often blamed on pollution or global warming.
But in a paper set to appear Friday (7/27) in the journal Science, 16
scientists and academicians from around the world argue that these
trends were set into motion by a much older human transgression:
overfishing.
Beginning long before Columbus and accelerating rapidly in Colonial and
modern times, people have radically overfished marine mammals, large
fishes and shellfish, according to the paper, whose co-authors include
Karen Bjorndal, a zoology professor and director of the Archie Carr
Center for Sea Turtle Research at the University of Florida. The
reduction of these animals to a fraction of their historical abundance
has caused ecological damage that remained hidden until recent decades,
when other circumstances triggered its full effects, the scientists say.
"What we're finding is a number of the crises that our marine ecosystems
are facing today can be traced back thousands of years in some cases,
and hundreds of years in others, to when human beings first began
affecting these ecosystems," Bjorndal says.
The paper is an unusual example of scientific literature, and not just
because of the number and diversity of authors, who range from
ecologists to paleobiologists and hail from institutions including the
University of Chicago, Australia National University and the Smithsonian
Tropical Research Institute.
In contrast to the narrow focus of many scientific papers, it discusses
coastal ecosystems around the globe, hopscotching from the Chesapeake
Bay to the Caribbean to Australia's coastal waters. And it steps outside
the bounds of pure ecological science, drawing on a broad array of
scientific literature, historical accounts and archaeological evidence
of aboriginal fishing practices.
Among the interesting tidbits that emerge: While overfishing reached its
zenith in Colonial and modern times, it was a problem in native
societies long before Europeans arrived, "contrary to romantic notions
of the supposedly superior ecological wisdom of non-Western and
pre-Colonial societies," the paper states.
The authors tie several recent downturns in the world's coastal
ecosystems to past overfishing. Examples include:
Declining underwater kelp forests -- Overfishing of sea otters in the
Northern Pacific - starting with aboriginal Aleutian fishing 2,500 years
ago -- has caused exploding sea urchin populations, the paper says. The
plant-eating urchins have decimated the kelp forests, a crucial habitat
for young fishes. Recent protection of otters has helped, but killer
whales now are eating the otters. That's because people have overfished
the fishes consumed by seals and sea lions - normally the whales' prey.
This overfishing has in turn slashed numbers of seals and sea lions.
Shrinking seagrass beds -- Bjorndal's research ties overfishing of green
sea turtles to the decline of turtlegrass in Florida Bay and in the
Caribbean. The connection: The turtles, which eat only plants, prevent
the turtlegrass from growing too long. In their absence, the longer
grass shades the bottom, slows the current and decomposes on the sea
bottom. This process both increases nutrients and encourages turtlegrass
diseases. "One of our best estimates is that green sea turtle
populations today are 5 to 10 percent of what they were when Columbus
arrived," Bjorndal says. "The functional loss of this species has had a
huge effect."
Declining shellfish beds -- The authors say overfishing of oysters in
the Chesapeake Bay has contributed to low oxygen levels and other
symptoms of nutrient pollution because the oysters no longer filter the
bay's water. The resulting degradation of water quality has in turn
prevented the oysters from regrowing. It has also spurred the outbreak
of microbial diseases potentially harmful to sea life and people alike,
such as Phisteria, a parasitic organism that has plagued North Carolina
coastal systems.
Bjorndal says scientists have missed the connection between past
overfishing and current ecological problems in part because they don't
feel comfortable working with historical data, which may not conform to
the rigors of scientific testing and experiment.
While it's true that past data may not be as complete as scientists
would like, the resulting lack of historical perspective has often led
to erroneous or incomplete conclusions about ecological problems, she
says. For example, scientists attributed a massive die-off of coral
reefs in the Caribbean in the 1980s to algae blooms spurred by the
decline of a then-abundant plant-eating sea urchin. While technically
accurate, she says, the bigger picture is the sea urchin was simply the
last herbivore left after people had fished out most plant-eating fishes
and turtles.
Indeed, data assembled by the scientists that compares historic
populations of sea life to current populations paint a bleak picture.
A century ago, an estimated 104,000 dugongs, a type of sea cow, swam in
the waters of Moreton Bay, Australia; now there are just 500. Where
Atlantic cod in the Gulf of Maine once measured an average of about 3
feet, today's average size is about a foot. Where seagrass beds covered
more than 76,000 acres in Tampa Bay less than 150 years ago, the grass
now encompasses just 26,000 acres.
Despite such declines, the authors conclude on a cautiously optimistic
note, saying most of the overfished species still survive in sufficient
numbers to permit restoration. Recognition and study of the past
richness of coastal ecosystems highlights "the extraordinary magnitude
of economic resources that are retrievable" and is a first step toward
rebuilding the systems to their past glory, they say.
"If we want to restore these ecosystems, we have to understand how they
function, and just looking back a couple of decades isn't going to tell
us," Bjorndal says.

Overfishing sets the stage for other problems in marine ecosystems
ORONO, Maine -- Overfishing of key marine animals such as cod, oysters,
sea turtles and other species is the primary cause leading to a variety
of problems that have appeared recently in coastal waters around the
world, according to an article published this week in the journal
Science. In locations ranging from the Chesapeake Bay to the Great
Barrier Reef in Australia, increases in disease, invasions of non-native
species and declining water quality can be traced back to a loss of
species that exert a controlling influence over marine ecosystems, the
authors conclude after a review of historical data that stretches back
thousands of years.
In the Gulf of Maine, evidence for the loss of large predatory fish is
clear, says co-author Robert Steneck of the University of Maine Darling
Marine Center in Walpole. While a cause and effect relationship between
the loss of those species and disease, water quality problems or the
spread of non-native species has not been demonstrated for the Gulf, it
can't be ruled out. "Taking a longer look at ecosystems gives us
perspective on how much things have changed," says Steneck.
"The big news here is that we haven't considered that fishing impacts
may have begun thousands of years ago and that some of the ecosystem
level changes may be indirect," he adds.
The article, "Historical Overfishing and the Recent Collapse of Coastal
Ecosystems," is co-authored by scientists from 14 universities and
scientific organizations around the world, including Steneck and Bruce
J. Bourque, a lecturer in anthropology at Bates College in Lewiston.
Jeremy B. C. Jackson of the Scripps Institution of Oceanography in La
Jolla, California, is the primary author. Science is published weekly by
the American Association for the Advancement of Science.
"In Maine, we have evidence from Indian middens dating back 5,000 years
that our coastal zone was dominated by large predatory fish such as cod.
The average size of cod for thousands of years was about a meter long
which is impressive considering the fishers used crude hooks made of
deer bone with line made of deer intestines. Coastal food webs were
probably dominated by large predators and many of the invertebrates such
as lobsters and sea urchins may have been much less abundant than they
are today," says Steneck.
"By any measure the rate of change in the world's coastal oceans is
accelerating. Whereas cod were harvested by humans as a primary food for
over 5,000 years and early Europeans saw cod as an inexhaustable
resource, it wasn't until the last half century that cod became rare in
coastal zones. Since then, increased lobster and sea urchin abundances
may be the result of those former prey species living in a new
predator-free world," he adds.
The article notes that a lack of historical perspective has led to
erroneous conclusions about the causes of problems in marine waters.
Such problems often have "deep historical roots," the article says. For
example, land use activities around Chesapeake Bay have been considered
the primary cause of water quality problems there. However, the loss of
massive oyster beds had severe consequences for water quality because
oysters kept the growth of water clouding algae in check. It was the
loss of oysters that made the ecosystem vulnerable, the article states.
In other examples, the article cites the elimination of predators such
as sea otters on the West Coast and of predatory fish from the Gulf of
Maine as the primary factor in the loss of kelp beds. Otters and
predatory fish kept sea urchins, which eat kelp, in check. Kelp
"forests" are important habitats that support diverse marine
communities. In recent years, urchin harvesting by humans has allowed
kelp to expand in some areas of the Gulf of Maine, Steneck points out.
In addition to overharvesting, disturbance of underwater habitats is
cited as a primary cause leading to the collapse of fish populations
around coral reefs in the tropics, the article states.
The paper is based on four types of records: modern ecological records,
historical information about fishing activities starting from the 15th
century, archeological records from human coastal settlements occupied
as far back as 10,000 years ago, and paleoecological data going back as
far as 125,000 years ago.
In many cases, evidence for large populations of marine creatures in the
past stands in stark contrast to relatively small numbers of such
animals today, the authors note. Examples of overfishing are cited in
aboriginal, colonial and modern cultures, but modern technology has
allowed harvesters to eliminate what had been considered an
inexhaustible marine resource, say the authors.
The historical perspective can be used to develop modern management
strategies that could help fish populations recover, the authors also
note. With some exceptions, most populations exist at levels that can be
restored through the use of "bold experiments to test the success of
integrated management for multiple goals on the scale of entire
ecosystems."
"Food webs are ghosts of what they once were," adds Steneck. "When food
webs are altered, the ecosystem changes. In Maine we have a very
unstable coastal ecosystem today with changes occurring at the scale of
years to decades, not centuries to millennia as was formerly the case.
"We don't understand all of the changes, but today there are areas
carpeted with blue mussels where they used to be rare. Rock crabs have
exploded to extraordinary density in some areas. Last year we relocated
tens of thousands of sea urchins to bring them back to an area where
harvesting has eliminated them, but they were all eaten by crabs. Change
is common in all ecosystems, but the rate and magnitude of change we are
currently seeing is unprecedented."

Famous coral reefs damaged due to global warming will take a century to
recover, says new research.
AS world leaders continue to debate climate change, new research has
revealed reefs damaged as a result of global warming in one of the
world's most exclusive diving areas will take at least a century to
recover.
Huge swathes of the coral at Rangiroa in French Polynesia died during
three months of exceptionally warm weather in 1998, when sea
temperatures soared to an average of 32 degrees centigrade for the first
time.
Research by Newcastle University's Department of Marine Sciences has
shown damage to the 800-year old coral reefs was catastrophic, and that
it would take more than 100 years to return to its former glory.
Dr Peter Mumby, Royal Society Research Fellow at the University said:
"Usually when sea temperatures rise, the coral usually withers slightly
but is able to recover.
"But in 1998 global warming caused the sea temperatures to soar to
incredibly high levels and in some areas of the ocean there were
sustained temperatures of 33-34 degrees centigrade - in previous years
temperatures averaged at 28 degrees.
"This caused the corals to die, and damage like this can only be
rectified over the long term - we think about 100 years."
Divers from all over the world enjoy the spectacular natural environment
at Rangiroa. As well as the coral reefs, it has one of the most wide
ranging selection of wildlife in the world - whales, dolphins, turtles
and manta rays. The lagoon is also a pearl farming area and a mecca for
hundreds of wealthy tourists each year.

Subject: Re: Planting the wrong tree increases air pollution - 7-24-2001 -
ENN.com
Since ENN provides no ready means of communicating with them (a
user-unfriendly "feature" if there every was one) regarding their content,
I will cast this upon the winds:
1. The article cited does not cite source research, not to mention whether
or not it was peer-reviewed, or repeated.
ENN gets a zero for credibility in my book.
WT
In addition, ENN follows the mass-media practice of having a "poll," and
asking people to "vote." Two strikes, and I quit looking for more. The
site's a good idea, but there must be a better one . . . ?

Subject: GIS and Remote Sensing Course
The Smithsonian Conservation and Research Center is offering the following
course this fall:
GIS & REMOTE SENSING FOR WILDLIFE MANAGERS
An Introduction to the use of Geographic Information Systems &
Remote Sensing in Conservation and Wildlife Management
OCTOBER 15 - 19, 2001
Increasingly, Geographic Information Systems (GIS) and Remote Sensing - the
mapping of features using imagery acquired either from an aircraft or a
satellite - have become important tools for decision making and the applied
management of natural resources. Many federal agencies and NGO's rely on
GIS and satellite data for their work and are starting to produce their own
spatial databases. However, there are few training opportunities for
wildlife managers to learn the application of GIS in everyday management
situations. We are offering a course for wildlife managers that will
provide hands-on experience for the collection of data, GIS analysis of the
data, and map making.
PROGRAM DESCRIPTION
This short course will provide wildlife managers with a working knowledge
about the application of Geographic Information Systems (GIS) and Remote
Sensing to the monitoring and management of wildlife and forest vegetation.
Exercises in establishing locations with a Global Positioning System (GPS),
data input into a GIS, and spatial analysis techniques for GIS will provide
hands-on and real world experience during the course. Based on examples
about habitat selection in songbirds and white-tailed deer, course
participants will learn how to:
* Collect GIS data in the field using survey techniques and GPS.
* Differentially correct GPS data.
* Input GPS data into GIS.
* Input field data into GIS.
* Use GIS for management of large data sets from multiple sources.
* Design and perform analysis using GIS data and spatial analysis
techniques.
* Integrate data with ancillary data, such as satellite imagery, aerial
photography, and State Agency databases.
TRAINING LOCATION
The course will be taught at the National Zoological Park's Conservation and
Research Center in Front Royal, Virginia. The Center is located at the
north entrance of the Shenandoah Park approximately 70 miles west of
Washington, D.C. Pick-up from Washington Dulles Airport can be arranged.
Participants will be housed at the CRC and meals provided at the CRC's
Conference Center. All computer labs will be taught at the Center's Spatial
Analysis Lab. The lab is equipped with various PC's, Macintosh, three UNIX
systems, two X-Terminals, a GPS Base station, two digitizers, and color
plotters and printers.
Visit the web address below for more details and registration information.
The CRC will also be offering an Advanced Course in Conservation GIS and
Remote Sensing. Information on this course is also available on the
following web address:

Subject: Advanced Conservation GIS Course
The Smithsonian Conservation and Research Center is offering the following
advanced Conservation GIS and Remote Sensing Course this fall.
Measuring Landcover Change and its Impact on Endangered Species
October 22 - 26, 2001
PROGRAM DESCRIPTION
This one-week advanced GIS and remote sensing course provides
conservationists with an opportunity to learn how GIS and remote sensing can
be used to assess the conservation status of endangered species. Each
participant will be provided with their own desktop computer for all lab
exercises. During the hands-on exercises participants will use the Internet,
ArcView, ArcView Spatial Analyst, ERDAS Imagine, Fragstats, and other
spatial analysis programs. Instructors will lead participants step-by-step
through the process of:
* conduct a regional conservation assessment using GIS to determine critical
conservation areas for an endangered species
* acquiring multi-date satellite imagery to quantify land cover change and
to map the extent of the remaining habitat
* using landscape analysis to determine optimal landscape configurations for
conserving the endangered species.
TRAINING LOCATION
The course will be taught at the National Zoological Park's Conservation and
Research Center in Front Royal, Virginia. The Center is located at the
north entrance of the Shenandoah Park approximately 70 miles west of
Washington, D.C. Pick-up from Washington Dulles Airport can be arranged.

To Whom May Be Interested:
I am interested in finding a map, from which a slide or series of
slides can be made, of the alpine areas in western North America. This
should include all areas from Arizona-New Mexico on the south to the
Brooks Range in Alaska on the north. Suggestions would be appreciated.
Please offer complete citations for any books/bulletins/pamphlets that my
be useful so that I can find them using normal library data bases. Thanks
