Subject: Summer Jobs in Forest Ecology in the Pacific Northwest
SUMMER JOBS IN FOREST ECOLOGY IN THE PACIFIC NORTHWEST
Field crew positions are available to assist with ecological studies in
forests of the Pacific Northwest. Crews will participate in the
Demonstration of Ecosystem Management Options (DEMO) project, a long-term
study of forest ecosystem responses to structural retention harvests in
the Pacific Northwest.
During summer 2003, we will be assessing patterns of tree growth and
mortality (both overstory and regenerating trees) in a diversity of
experimental treatments and forest types. Field sites are located in
western Oregon and Washington.
These positions are best suited to mature, upper-level undergraduates or
recent graduates who are giving serious consideration to advanced study or
professional work in forest ecology or silviculture. The nature of the
work requires extended periods in the field (up to 8 consecutive days).
Bunkhouse space is available for portions of the summer, but camping may
be necessary at other times.
QUALIFICATIONS: Previous experience in vegetation sampling; familiarity
with basic surveying and mensurational tools (compass, clinometer,
diameter tape); and course work in silviculture, forest ecology, or a
related field. Candidates must be in good physical condition; able to
work long hours; and capable of navigating steep, slash-covered slopes.
We seek individuals who are detail oriented, have legible handwriting, and
can work and live cooperatively with others.
SALARY: $9.00/hour or more, depending upon experience/qualifications.
DURATION: late June through September 2003
CLOSING DATE: March 1, 2003
TO APPLY: Send (1) handwritten cover letter; (2) typewritten resume;
(3) copies of either college transcripts or professional work products;
and (4) two letters of reference. The cover letter should include
information about your interests and qualifications, your dates of
availability, and the names and phone numbers of those who will provide
letters of reference.

Subject: [Fwd: Re: CCA]
Laura, I forwarded your message to one of my statistically minded
colleagues, Gavin Simpson. Below is his reply.
Good luck.
Ewan Shilland.
>From Gavin:
Hi,
Eigenvalues and the eigenvectors are the result of the matrix decomposition
used to produce the results. Eigenvalues can simply be thought as the
amount of the variance in your data that are explained be each axis of on
ordination. If you have small Eigenvalues (as a proportion of the total
inertia/variance value) then this would suggest that they extracted axes and
hence your environmental data do not explain large amounts of the variance i
your microbiological data. However, three things to consider:
1) is CCA appropriate for your species data? Do your species exhibit
unimodal response to your environmental data or underlying CA axes? (use
DCA and DCCA in Canoco for example to test this, where a gradient length of
>3 would indicate unimodal responses. Less than this and RDA might do a
better job so try both). Have you tried a transformation for your species
data? A sqrt or log transformation of the species data might help to reduce
the variance in the data, which may then be better explained by the env
data. Remember that only LINEAR combinations of your environmental data are
used. Your species might respond exponentially etc, so perhaps a
transformation of the env data could be tried, i.e. a log transformation is
often used with water chemistry data for example, and species often respond
to the logarithm of a variable?
2) Do you have many "rare" species? CA and therefore CCA is affected by
rare species (outliers). As such, certainly in my field, we try to drop out
rare taxa (say less than 1% abundance in 2 or more samples) and see what
effect that has on the ordination.
3) I don't really understand the next point fully, but see Xkland, R.H.
1999. On the variation explained by ordination and constrained ordination
axes. - J. Veg. Sci. 10: 131-136 for a better explanation...
[this is summarised from a discussion on the ORDNEWS listerver with postings
by Jari Oksanen and Rune Xkland amongst other]
...but basically, species respond in complex ways to underlying
environmental gradients with mixtures of linear, unimodal and truncated
response curves. This property of environmental data leads to CCA/RDA
extracting axes which are polynomial distortion axes of the main axes which
do relate to your environmental data. Now, because one has already
explained this variation in the main axes, the polynomial axes tend to
inflate the amount of variation in the data set => a larger reported tota
variance/inertia. Obviously your env data now do not explain as much of
this inflated variation as they did of the "real" variance. This problem
arises because the linear species response (in PCA/RDA) and the "species
packing model" in CA/CCA are not adequate to model this complex ecological
data. So one can think of the low eigenvalues as being the result of a
'lack-of-fit-of-data-to-model'. Furthermore, a number of ecostatisticians
have expressed reservation as to the measures of variance/inertia in
ecological data used in ordination methods (PCA/RDA/(C)CA), with which the
eigenvalues are compared.
Follow the other suggestions and look at Mike Palmer's web site for more
information (also try to get hold of a copy of Legendre & Legendre (1998)
Numerical Ecology, 2nd English Edition, Elsevier, which has a good
discussion of matrix algebra in general and of PCA/RDA/(C)CA in particular),
but I wouldn't be too bothered about the low eigenvalues. This might
indicate that you haven't measured the (more)important variables, or it
might just be the result of complex ecological data (your data will be noisy
etc.). CCA is giving you a result, now try to interpret it. And one
outcome of Xklands paper is that is very difficult to compare the absolute
variances explained by ordination axes across data sets etc. One would be
better sticking to thinking in terms of the relative sizes of the
eigenvalues instead.
Hope this is of some use to you,
Gavin Simpson

Laura,
One of the best on-line sources of information about ordination in
particular and CCA in particular is Michael Palmer's ordination web
site . I've used it
many times myself to figure out what's going on.
A good hard-copy reference is the chapter by ter Braak on ordination.
The full reference is: ter Braak, CJF. 1995. Ordination. In
Jongman, RHG, CJF ter Braak, OFR van Tongeren (eds.). Data analysis
in community and landscape ecology. Cambridge University Press,
Cambridge. pp. 91-173.
Eigenvalues are conceptually difficult to understand. That's part of
the reason that I've turned to fuzzy set ordination. Here's a
shameless plug for my web site on fuzzy set ordination
. Like CCA, FSO is a direct
gradient analysis or constrained ordination method, which means you
are testing whether a particular gradient is responsible for the
patterns seen in your data. If you want to use indirect gradient
analysis, Bray-Curtis or polar ordination is the unconstrained
version of FSO (in this case, you are using data exploration to get
some idea of what the major gradients in your data might be; after
finding gradients, you can do some post-hoc tests to see what they
are correlated with). I find FSO easier to understand. However, CCA
has software packages written for it, such as CANOCO and PC-ORD,
which make it easy to apply. With FSO, you will have to engage in
some SAS coding. Also, the strengths & weaknesses of CCA are
well-known by now, and Michael Palmer has a good summary of them.
FSO is much well-less understood (but I'm working on it!). Good luck!

Subject: data request
Dear Ecologers,
Prof. David H. Wise and I are working on a new statistical technique for
testing treatment effects on multi-species responses in field experiments
with a relatively simple design. i.e. two treatments, or the ability to
order the treatments if the levels are more than 2.
We would like to prepare a paper on the subject and would also like
to use data other than ours for that purpose. For this reason we are
asking for data (preferably published data) from simple experiments (2
treatments, or > 2 as long as they can be ordered ^ж e.g. amount of
fertilizer added) involving several species (s > 10) and with several
replicates per treatment (ideally n > 10).
Experiments on any system are welcome. It would be preferable that
the species are likely to interact, such as competitive or predator-prey
interactions.
Please contact me at jmoya2@uky.edu, or David Wise at
dhwise@uky.edu.
Thank you very much in advance for your help.

Dear Yaron, dear fellow ecologists,
You can find a few words about spectral analysis in ecology in Mark R. T.
Dale's book "Spatial pattern analysis in plant ecology" (Cambridge
University Press, 1999). There are examples for both single species and
multispecies studies (chapters 3 and 5, respectively). Apart from
references to specialized textbooks, Dale only refers to two published
papers using spectral analysis in ecology :
Kenkel, N. C. 1988. Spectral analysis of hummock-hollow pattern in a weakly
minerotrophic mire. Vegetatio 78: 45-52.
Ripley, B. D. 1978. Spectral analysis and the analysis of pattern in plant
communities. Journal of Ecology 66: 965-981.

Subject: Re: Spectral analysis in ecology
We use spectral analysis all the time in remote sensing (its the core of
what a remote sensor does). There is a wealth of literature on the
subject -- you can check out our lab's website at www.cstars.ucdavis.edu,
we use an imaging spectrometer (AVIRIS) to produce images where each pixel
has a continuous spectrum in which we can analyze absorption features,
perform wavelet analyses, and just about anything else you can think of
doing with spectrum, and then scale in the information across a
landscape... I'd argue this is the most advanced use of spectral analysis
in ecology... We can do neat things like calculate LAI, biomass, leaf
water content, canopy structure, species assemblages, etc, etc...

VANISHING ICE. ONE IN AN OCCASIONAL SERIES.
Melting Ice, Winds of Change
The Northwest Passage is thawing, which carries major implications
for shipping, the environment and the Inuit way of life.
By Usha Lee McFarling, Times Staff Writer
RESOLUTE BAY, Canada -- For 500 years, explorers nudged their ships
through these Arctic waters, vainly seeking a shortcut to the riches of
the East. The Northwest Passage, a deadly maze of sea ice, narrow straits
and misshapen islands, still holds the traces of those who failed.
There are feeble cairns, skeletons lying face down where explorers fell,
makeshift camps piled high with cannibalized bones and, on one rocky spit,
a trio of wind-scoured tombstones. Whole expeditions, hundreds of men and
entire ships, are missing to this day. The first explorer to survive a
crossing, in 1906, spent several winters trapped by ice.
Despite that -- or maybe because of it -- Canadian Mountie Ken Burton
wanted nothing more than to join the pantheon of polar explorers who had
threaded their ships through the passage's narrow ice leads and around its
shimmering blue-green icebergs.
In the summer of 2000, Burton gingerly nosed a 66-foot aluminum patrol
boat into the heart of the Northwest Passage. Ice floes could crumple the
boat like paper. Even the smallest iceberg, a growler, could rip apart its
delicate hull.
But there were no bergs. No growlers. No thin cakes of pancake ice. To his
surprise, Burton found no ice at all. A mere 900 miles south of the North
Pole, where previous explorers had faced sheets of punishing pack ice,
desperation and finally death, Burton cruised past emerald lagoons and
long sandy beaches. Crew members stripped and went swimming. Burton
whipped through the passage, "not hurrying," in a mere 21 days.
"We should not, by any measure, have been able to drive an aluminum boat
through the Arctic," said Burton, still astonished and just slightly
disappointed. "It was surreal."
It was also a glimpse of the future. For several summers now, vast
stretches of the Northwest Passage have been free of ice, open to
uneventful crossings by the flimsiest of boats. Climate experts now
blandly predict what once was unimaginable: In 50 years or less, the
passage will be free of ice throughout the summer, a prospect that could
transform the region and attract a flotilla of cruise ships, oil
supertankers and even U.S. warships.
"It's something no one would have dreamed up for our lifetime," said
Lawson Brigham, deputy director of the U.S. Arctic Research Commission and
former captain of the U.S. Coast Guard icebreaker Polar Sea, which made it
through the passage in 1994.
The parting of the ice is the product of natural, long-term atmospheric
patterns that have warmed the Arctic in recent decades and, to a lesser
extent, the gradual heating of the planet by greenhouse gases.
The planet's temperature has risen 1 degree Fahrenheit over the last
century. In the Arctic, temperatures have risen 3 to 4 degrees. In these
northern seas, at the boundary between water and ice, that small
difference has changed the landscape for thousands of miles.
"The image of the Arctic was always one of an ice-locked, forbidden spot,"
said James P. Delgado, director of the Vancouver Maritime Museum and
author of "Across the Top of the World: The Quest for the Northwest
Passage." "If we as a species have wrought this change, it's humbling,
given its history as such a terror-filled place."

Subject: Ph.D. student or Postdoc Position
Effects of Household Dynamics on the Environment
A postdoctoral associate or Ph.D. student is sought to expand an
interdisciplinary study on the effects of household dynamics (changes in
the number of households and number of people in a household) on the
environment (e.g., biodiversity, landscapes, and natural
resources). According to a recent study (Liu et al.; Nature, 2003), the
number of households has been increasing much faster than population size
globally. In both developed and developing countries around the world,
households are generally getting smaller in size. This phenomenon is
especially evident in countries containing biodiversity hotspots. Human
population size and growth rate are traditionally considered important
factors affecting the environment, while household dynamics are usually
ignored although they have dramatic impacts on the environment through
household consumption of resources (e.g., land, energy) and the
environmental effects of declining fertility may be offset by higher per
capita consumption in smaller households.
We are looking for highly self-motivated applicants with backgrounds in
various fields, such as ecology, human demography, sociology, economics,
geography, wildlife biology, biodiversity conservation, land use and land
cover changes, and/or human-environment interactions. Strong quantitative
skills (e.g., remote sensing, geographic information systems, computer
modeling, mathematics, and/or statistics) are required. Experience with
analysis of human population survey and census data is
desirable. Stipends/salaries and benefits are competitive. Start date is
negotiable.
Reviews of applications will be conducted periodically and will continue
until the position is filled. Interested individuals are encouraged to
provide the following materials as soon as possible: (1) cover letter
indicating general and specific research interests/experiences,
(2) statement of professional goals (e.g., plans after finishing the
postdoctoral or doctoral training), (3) resume, (4) transcripts, (5) list
of three references (names, email addresses, phone numbers, and postal
addresses), and (6) GRE scores and TOEFL scores (TOEFL scores are required
for applicants whose native language is not English). (Photocopies of
transcripts and GRE/TOEFL scores are okay initially.)

Subject: Postdoc Position
Integrating Ecology and Economics for Forested Landscapes
A postdoctoral associate is sought to join an interdisciplinary team that
integrates ecology and economics for forested landscapes. The current team
members include Jianguo (Jack) Liu (systems modeler), Frank Lupi (resource
economist), Mike Walters (forest ecologist), three Ph.D. students, a
postdoctoral fellow (wildlife ecologist), and a number of collaborators
from several resource management agencies.
This integrated project takes a systems approach to examine ecological and
economic effects of forest management on both public and private lands in
a large region (approximately 1 million ha) of Michigan's Upper
Peninsula. The region is currently managed for timber harvest, deer
hunting, bird watching, and tourism. The project objectives are
to: (1) quantify the effects of forest harvesting practices and deer
populations on vegetation structure and composition; (2) evaluate the
effects of vegetation composition and structure, in a landscape context,
on deer and forest bird populations; (3) assess economic values of wood
products, deer hunting, aesthetics, forest bird diversity and plant
diversity; and (4) predict the ecological and economic effects of new
management scenarios across the landscapes. The completion of this project
will provide critical multi-scale information on ecological and economic
responses across managed landscapes, economic trade-offs among various
forest products and ecosystem services, and ways to optimize the choice
and spatial arrangement of management options on the landscapes to improve
and sustain natural resources.
We are looking for a highly self-motivated individual to help coordinate
this project and develop modeling and simulation tools for integrating
various components of this project. Applicants should have solid
backgrounds in landscape/forest/wildlife ecology, resource economics,
environmental economics, and/or natural resource management. Strong
quantitative skills (e.g., computer modeling, mathematics, geographic
information systems, and/or statistics) and programming experiences (e.g.,
C, C++, or Java) are required. Salaries and benefits are competitive. The
starting date is negotiable.
Reviews of applications will continue until the position is
filled. Interested individuals should provide the following materials as
soon as possible: (1) cover letter indicating general and specific
research interests/experiences, (2) statement of professional goals (e.g.,

Laura,
One of the best on-line sources of information about ordination in
particular and CCA in particular is Michael Palmer's ordination web
site <http://www.okstate.edu/artsci/botany/ordinate/>. I've used it
many times myself to figure out what's going on.
A good hard-copy reference is the chapter by ter Braak on ordination.
The full reference is: ter Braak, CJF. 1995. Ordination. In
Jongman, RHG, CJF ter Braak, OFR van Tongeren (eds.). Data analysis
in community and landscape ecology. Cambridge University Press,
Cambridge. pp. 91-173.
Eigenvalues are conceptually difficult to understand. That's part of
the reason that I've turned to fuzzy set ordination. Here's a
shameless plug for my web site on fuzzy set ordination
<http://www.nku.edu/~boycer/fso/>. Like CCA, FSO is a direct
gradient analysis or constrained ordination method, which means you
are testing whether a particular gradient is responsible for the
patterns seen in your data. If you want to use indirect gradient
analysis, Bray-Curtis or polar ordination is the unconstrained
version of FSO (in this case, you are using data exploration to get
some idea of what the major gradients in your data might be; after
finding gradients, you can do some post-hoc tests to see what they
are correlated with). I find FSO easier to understand. However, CCA
has software packages written for it, such as CANOCO and PC-ORD,
which make it easy to apply. With FSO, you will have to engage in
some SAS coding. Also, the strengths & weaknesses of CCA are
well-known by now, and Michael Palmer has a good summary of them.
FSO is much well-less understood (but I'm working on it!). Good luck!

I have a student conducting field behavioral studies on scale insects

dead of winter there is nothing happening. Does anyone have a
suggestion of a good lab system that we could use. Any ant-tended
homopteran that meets the following caveats would do:
1. the secretions of the homopteran must be visible and countable
2. the homopteran is available (either commercially, through a govt.
organization or through someone's generosity!)
3. the hostplant needs to be something that we can grow up in a
relatively short time period (e.g. one month).
I have several ant colonies in culture that we can use (Tapinoma
sessile, Paratrechina, and Solenopsis richteri).
If anyone has any suggestions of systems for use and where I might
get a starter colony of homopterans, please let me know.

http://ens-news.com/ens/jan2003/2003-01-10-09.asp
Beach Water Pollution Can Be Tracked to Its Source
IRVINE, California, January 10, 2003 (ENS) - A California study may help
beachside communities identify the sources of water pollution affecting
beach water.
The study has proved instrumental for improving the quality of beach water
in Avalon, Catalina Island, a popular California tourist destination. The
research shows that it is possible to identify and track the specific
sources of water pollution by combining bacteria sampling with genetic
testing.
By combining these methods, the researchers found that decaying sewage
pipes in the downtown area adjacent to Avalon Bay had been leaking human
waste into the shoreline water. As a result of the research, Avalon
officials sliplined the city's sewer lines to seal the leaks and are
investigating connecting pipes from private businesses and homes for
further leakage.
Their work has already decreased bacteria levels along the shoreline by
more than 50 percent, and beach closures declined from 31 in 2001 to 15 in
2002.
The approach provides a new method for coastal agencies to comply with
tougher beach water quality laws. Beaches are now tested for fecal
indicator bacteria using methods that only provide general information on
potential sources for pollution. High bacteria content can lead to beach
closures.
"Right now, beach communities are faced with bacterial pollution without
knowing their sources," said lead author Stanley Grant, an environmental
engineer at the University of California at Irvine (UCI).
"The combination of indicator sampling and genetic testing has the
potential to make a real difference in efforts to clean up polluted
beaches," Grant added.
The study, coauthored by University of Southern California microbiologist
Jed Fuhrman, Alexandria Boehm of Stanford University, and Robert MrЙe of
UCI, was posted Thursday on the Research ASAP site of "Environmental
Science & Technology." <>

Subject: Question on matrix averages
Dear Ecologgers,
I study the population dynamics of Geonoma
brevispatha,a clonal understory palm that occurs on
swampy forests of soth-central Brazil.
At the moment I am analysing the dynamics of
ramets inside each independent genet in my local
population using matrix models. Could someone give me
a light in a little problem?
We have circa 160 genets, each of which is
comprised by ramets spanning four ontogenetic stages,
from Juveniles to Reproductives (circa 2000 ramets in
the whole population). We are building a transition
matrix reflecting ramet dynamics for each genet. Our
intention is to obtain a ramet population growth rate
for each genet and then test the presence of any
correlations with environmental variables such as
light availability and soil water status, as well as
using this rate as a measure of each genet health,
since it is very difficult to obtain mortality rates
for genets, which are very long-lived.
The problem is that the majority of genets do
not have full rank matrices, but lack specific
transitions instead. If lacking, these transitions
will cause distortions in the calculation of lambda.
So I will fill these matrix cells with average
transitions obtained from the population as a whole,
as you did in Horvitz and Schemske (1995). Here cames
my doubt. As long as I have understood, there are two
ways of doing this:
1 - to pool all individual ramets in the population
as if they belonged to a single genet, obtain the
transition matrix of this global genet, representing
all possible transitions and its values, and use them
wherever one specific transition is lacking in any
genet in particular
2 - average the values of each cell of the 160
matrices of all particular genets and use these
average values wherever one specific transition is
lacking in any genet in particular
Are these two alternatives really valid? Which do
you consider the best one and why?
Thank you in advance for your
attention.
All the best for you in 2003!
Sincerely,
=====

WILDLIFE MANAGEMENT FIELD COURSES
EcoLife Expeditions, South Africa
International Universities Program
SESSIONS OFFERED:
16 May - 14 June 2003
20 June - 19 July 2003
25 July - 23 August 2003
ACADEMIC CREDITS: 8 credits from the University of Pretoria.
COST: $2600 (US dollars)
Join us for our wildlife management course where the African bush is our
classroom. Learn about managing African wildlife as we travel through
the African savannah studying real life parks and participating in
hands-on projects.
Our 30 day Wildlife Management Courses are for students and
professionals interested in African conservation. The course includes
lectures, classes and hands-on projects taught by instructors from the
University of Pretoria's Centre for Wildlife Management.
Course participants interact with the research scientists and wildlife
professionals in the field, and our participants get involved in
on-going research. Lectures, classes and projects take place throughout
the trip from our mobile classroom.
COURSE TOPICS:
* Wildlife Management Techniques
* Sustainable Resource Utilization
* Ecosystem and Biodiversity Conservation
* Reserve and Resort Management
* African Local Community Cultures and Conservation Perspectives
* Africa Tourism Principles and Historical Sites
Our program is open to students of all ages as well as professionals in
wildlife biology, wildlife management, conservation, ecotourism and
rural peoples sociology.
The course is divided into two parts, as follows:
ECOSYSTEMS MANAGEMENT
Taking biotic and abiotic factors of each region into account, we
participate in formulating management strategies for game animals in the
different ecosystems that we will examine. As a part of the experience,
we learn about the adaptation of game to specific areas and the dynamics
of game populations under these conditions. Topics that we will cover
include animal behaviour, water utilisation, game condition, diseases,
parasites, nutrition, feed selection, game capture and relocation.
PEOPLE IN CONSERVATION
In this section, welearn about grazing and browse capacity and general
concepts of carrying capacity in a multi-species park. This includes
tourist carrying capacity and how to manage a game lodge in a way that
maximizes the experience of the tourist yet minimizes the impact on the
environment. We learn about road layout and fire as a management tool.
You will also learn about the importance of historical and cultural
sites and see first hand how many of these places are maintained by
local communities for a livelihood as a part of ecotourism.
WHO WE ARE
EcoLife is endorsed by the Centre for Wildlife Management at the
University of Pretoria. The Centre for Wildlife Management has been
producing graduates in Wildlife Management since 1965, and many leaders
in the field have qualified from this school. By drawing on the
outstanding expertise and experience of the staff and graduate students
from the Centre, EcoLife offers a unique experience to those with a
special interest in wildlife.
OUR MISSION
The mission of EcoLife Expeditions is to provide an exclusive, in-depth,
educational experience to people with a special interest in wildlife,
equipping them to make contributions to the sustainable management of
natural resources.

Subject: Post-doctoral positions and graduate student assistantships
Post-doctoral positions and graduate student assistantships
Two (2) post-doctoral research positions and two (2) graduate research
assistantships are available immediately in the following areas:
1. Coupling of biogeochemical cycles: To study dynamics of carbon,
nutrients, and water in forest/grassland ecosystems using either
experimental or modeling or both approaches and to link ecosystem-scale
studies with regional and global modeling. We particularly encourage
innovative approaches to study coupling among carbon, nutrient, and
hydrological cycles.
2. Inverse analysis in ecology. To develop and apply inversion approaches
to data assimilation from field CO2 and warming experiments.
The goal is to extrapolate results from manipulative experiments, where
ecological responses to a rather abrupt perturbation are measured, in order
to ultimately understand and predict long-term ecosystem responses to a
very gradual climatic change in the real world. Inverse analysis usually
requires mathematic and statistical skills together with basic ecology
training.
3. Soil respiration: To conduct mechanistic studies to examine how
substrate, temperature, and moisture individually and/or interactively
regulate soil respiration. We are particularly interested in manipulative
experiments using micro- and meso-cosms for the mechanistic studies.
We currently conduct collaborative research primarily at four sites:
warming experiments in Oklahoma, the Duke Forest Free Air CO2 Enrichment
(FACE) experiment in North Carolina, the Niwot Ridge AmeriFlux measurements
in Colorado, and mesocosm experiments in Nevada.
Descriptions of the four experimental sites are available at the website
http://bomi.ou.edu/luo. The successful post-docs and graduate students can
use any of the four sites for their research.
To apply, send letter of application indicating areas of research interest
and qualifications, current curriculum vitae, research publications, and
names, email and postal addresses, and telephone numbers of at least three
professional references to: Dr.Yiqi Luo, Department of Botany and
Microbiology, University of Oklahoma, Norman, OK 73019, email: yluo@ou.edu.
Applications will be received until the positions are filled.
