Subject: Re: The Junk Science of George W. Bush

And let us not forget the 1.2 billion dollars George Bush has slated for
hydrogen fuel cell research that went to a few major oil companies in order 
o
conduct research on how best to extract hydrogen fuel from petroleum product
. Of
course, a few people would probably have thought the money better spent on
water & renewable energy related hydrogen fuel research, but with executives
from BP, Shell, and ChevronTexaco on the hydrogen fuel cell discussion panel
(which drives the research and awards the funds) it seems our over dependenc
 on
fossil fuels will be assured for years to come.

    [ Your display is set for the "US-ASCII" character set.  ]
    [ Some characters may be displayed incorrectly. ]

Severe Cuts Proposed for EPA STAR Research Grants and Fellowships

Extramural research grants and graduate fellowships administered by the
U.S. Environmental Protection Agency (EPA) would be severely cut under the
President's budget request for FY 2005.  EPA's Science to Achieve Results
(STAR) graduate fellowship program would be cut by 33.5 percent relative to
the FY 2004 enacted level.  EPA's larger STAR research grants program would
be cut by approximately 30 percent or $36 million.  Approximately 93 fewer
STAR research grants would be awarded, according to EPA's budget
justification to Congress.  Deep budget cuts in EPA's STAR programs have
been proposed less than one year after the National Academy of Sciences
(NAS) issued a laudatory report entitled The Measure of STAR.

STAR Graduate Fellowships.  Funding for STAR graduate fellowships would
decrease by $3.1 million, or 33.5 percent, relative to the FY 2004 enacted
level.  STAR is the only federal fellowship program designed exclusively
for students pursuing advanced degrees in environmental
sciences.  According to the National Academy of Sciences report, "The STAR
fellowship program is a valuable mechanism for enabling a continuing supply
of graduate students in environmental sciences and engineering to help
build a stronger scientific foundation for the nation's environmental
research and management efforts."

The President's budget request proposed even deeper cuts in the STAR
graduate fellowship program in the past two years.  The budget request
would have cut funding for the STAR graduate fellowship program by 50
percent in FY 2004 and by 100 percent in FY 2003.  Congress restored full
funding for the EPA STAR graduate fellowship program in both years.  NCSE
is working to restore full funding for the program again in FY 2005.

STAR Research Grants.  The proposed cuts to EPA's STAR research grants
program are somewhat surprising because the National Academy of Science
judged the program "excellent" in a recent report.  Harold Mooney,
Professor of Environmental Biology at Stanford and chair of the NAS
committee, said the STAR program "^Åhas provided EPA with independent
analysis and perspective that has improved the agency's scientific
foundation.  By attracting young researchers, this program has also
expanded the nation's environmental science infrastructure."  According to
the NAS report, "the STAR program should continue to be an important part
of EPA's research program."

Research programs that would be affected by the proposed cuts in EPA STAR
funding are listed below.  Funding cuts are expressed relative to the
Administration's FY 2004 budget request rather than the FY 2004 enacted
funding levels, which are not yet available.

* Ecosystems Protection (-$22.2 million):  Approximately 50 STAR grants for
research on ecosystem stressors and effects would be eliminated.  Research
that would be discontinued includes development of indicators for regional
estuarine systems, development of genomic water indicators, and research on
invasive species' potential to invade vulnerable ecosystems.  According to
the agency's budget documents, "As a result of this reduction, STAR efforts
designed to establish or improve the connection between ecosystem stressors
and effects, serving as input to decisions at the regional, state, and
local levels, will be discontinued."
* Pollution Prevention (-$5 million):  Over 20 research grants would not be
funded under the Technology for the Sustainable Environment (TSE) program,
which is a collaborative effort with the National Science Foundation.
* Endocrine Disruptors (-$4.9 million):  Approximately 18 STAR research
grants for research on endocrine disrupting chemicals would be
eliminated.  According to EPA, grants for research in computational
toxicology, and research on mitigating the effects of endocrine disrupting
chemicals from concentrated animal feeding operations will not be awarded.
* Mercury Research (-$2 million):  The approximately 5 STAR grants that
support mercury research would be eliminated.  The research supported by
those grants would support understanding of the fate of atmospheric mercury.
* Hazardous Substance Research Centers (-$2.3 million):  A five-year
program that awarded grants for hazardous substance research would not be
funded in FY 2005.  According to EPA, some multi-year grants would not be
funded in their final year due to this cut.

Other EPA Research Programs.  Other EPA research programs would be cut
under the FY 2005 budget request, including the following programs:

* Homeland Security Building Decontamination Research (-$8.3
million):  Research on building decontamination for homeland security would
be completely eliminated.
* Environmental Technology Verification (-$1.0 million):  One or two
centers for testing the effectiveness of commercial environmental
technologies would be closed.

Environmental Education.  All funding for the EPA Office of Environmental
Education, which EPA established to implement the 1990 National
Environmental Education Act, would be eliminated according to the
President's FY 2005 budget request.  The office received approximately $10
million in FY 2004.

Overall EPA Budget.  EPA's STAR research grants and fellowship programs
would receive more drastic cuts than the total EPA budget, which would
decline by 6.9 percent relative to the FY 2004 enacted level.  EPA's
Science and Technology account would be cut by 11.8 percent, $92.5 million,
to $689.2 million in FY 2005.  The proposed budget includes increases for a
few research-related programs, including $2.0 million to implement
information quality guidelines.

From: Patrick Foley <patfoley@CSUS.EDU>
Subject: Return of R(t) versus lambda(t)

Ecologers!

During the Winter holiday, I sent out this message to which I received
_one_ response. I really would like to get some response this time. As a
pedagogical matter and to standardize the methodology for conservation
practice, it really is important.

Patrick Foley patfoley@csus.edu



I would like to see if a consensus can be obtained from this group about
two of the most important terms used in population ecology.

Over the past few years it has become usual in ecological papers and
texts (see Molles for example or the papers in the recent volume on
Wildlife population growth rates) to use the Greek letter lambda as the
symbol to denote a population multiplier. Thus

lambda(t) = N(t+1)/N(t)

This term does not yet have a satisfactory name. It is often called the
"finite population growth rate" or "net fundamental growth rate" or the
like. Perhaps a better term would be "realized population multiplier".
Similarly r(t)= log(lambda(t)) is very poorly named the "intrinsic
population growth rate" since there is very little intrinsic about it. A
better term might be "realized per capita growth rate".

My questions are these:
1) I have almost given up over lambda (t), but the notation is tricky
since it is easily confused with lambdasub1 the dominant eigenvalue of a
population projection matrix. I would prefer to use R(t)=N(t+1)/N(t), an
older, more British convention. Rsub0 is the population multiplier per
generation. R is the multiplier per time year (or other time unit). Is
this still worth fighting over? Has lambda(t) won?

2) Why not call lambda(t) the "realized population multiplier" when it
comes from data, and the "population multiplier" when it arises in
theory. Wat the heck does "finite population growth rate" mean anyway?

3) Why not call r(t) "per capita growth rate"? Please can't we stop
calling it "intrinsic"? Maybe rsubm, the Malthusian parameter is
intrinsic, but certainly not r(t) which is affected by density
dependence, environmental stochasticity, age structure, demographic
stochasticity and dozens more.

Now please note that I am already ruling out Peter Turchin's definition
r(t) = log(N(t)/N(t-1), as creating too much confusion with everybody
else. And I don't even want to get started about Royama's definitions or
  the almost random notations used by mathematicians who dabble in
ecological theory. This is day-to-day ecological vocabulary that needs
to be consistent for pedagogical, conservation and even legal reasons.

    [ Some characters may be displayed incorrectly. ]

Dear colleagues,

I am interested in understanding the relationship between hydroperiod (water
body duration) and primary productivity. Are there any general, consistent
patterns?

A common hypothesis is that periodic drying accelerates decomposition and
mineralization rates, which should increase nutrient availability for
primary producers. However, to my knowledge there is mixed support for this
hypothesis, as the relationship may depend on dissolved oxygen
concentrations in the water body. Periodic drying might increase
mineralization rates if ponds become anoxic, but not if have consistently
high DO levels (by the way, how low DO has to be for a water body to be
considered ^Ñanoxic^Ò for decomposing microorganisms?).

I am studying anuran larvae distributed across a hydroperiod gradient, and
thus I am more interested in smaller water bodies (lentic; ponds and
wetlands ranging from ephemeral to permanent), rather than big lakes. Also,
I am more interested in algal productivity, but macrophyte productivity is
also relevant for its contribution to detrital food webs.

Any input and suggestions of literature are greatly appreciated.

Uh, yeah, I did leave out that critical word "than".  Travel is the
number one drawback in consulting.  Consultants, particularly to start,
are often on the road Monday through Thursday, although in some kinds of
firms it's substantially less than that. In some cases, it may not
matter to the firm where you actually live.  For others, like strategy
consulting, being near the home base is important since a lot of the
work involves research and modeling, rather than work at the client
site.

Thanks for catching that!

You confused me on one point below, where you said that travel
requirements "are a lot less for consultants," relative to academicians.
Did you leave out the word "than"?  I think that consultants must travel
a lot more than do academicians.  Of course, a good many academicians
are also consultants. But generally, most of us in academia may travel
for field work or not, depending on our research, and usually attend
only a small number of meetings a year.

Subject: Re: Return of R(t) versus lambda(t)

OK, since you want a response, here's one from a naive (mis)user of
these terms.
I use R as the dicrete-time analog of r, as in
N(t+1)=N(t)+rN(t) (continuous-time, exponential growth)
N(t+1)=N(t)+RN(t) (discrete-time, geometric growth)
which makes N(t+1)/N(t)=1+R=lambda.
I don't know if that makes matters better or worse. It would be nice if
R and Rsub0 were closer in meaning - that does create unending confusion
among my students. The matter of eigenvalues does not arise for me, as I
teach mainly undergraduates and a few grads w/ little or no math
background.
I agree completely that the nomenclature for these symbols is
inconsistent and confusing. But I don't know what we can do about it at
this point. The literature is already full of these terms. I try to wean
my students from the words (and symbols), in an attempt to get them to
understand the concepts, but I have to admit it's not a very effective
strategy.
I use Molles in my Intro Ecology course, and I find his treatment of
population growth difficult to teach. It seems backward to me. I prefer
to teach simple, non-age-structured models first, and show their
implications, applications, and limitations. Then I show how the age
(stage, size) structured models improve on them. For what it's worth, I
also prefer the dicrete-time models because then I can avoid the
calculus (which few of my students have had), and because I can get
chaos easily and naturally, which is kinda fun.
Another area of confusion, which you don't really address, is the
distinction between model parameters (assumed to be constants) versus
real-world values, which obviously vary. I try to deal with this by
using time subscripts for varying values, and leaving the subscripts off
of constants.

During the Winter holiday, I sent out this message to which I received
_one_ response. I really would like to get some response this time. As a
pedagogical matter and to standardize the methodology for conservation
practice, it really is important.

Patrick Foley patfoley@csus.edu



I would like to see if a consensus can be obtained from this group about
two of the most important terms used in population ecology.

Over the past few years it has become usual in ecological papers and
texts (see Molles for example or the papers in the recent volume on
Wildlife population growth rates) to use the Greek letter lambda as the
symbol to denote a population multiplier. Thus

lambda(t) = N(t+1)/N(t)

This term does not yet have a satisfactory name. It is often called the
"finite population growth rate" or "net fundamental growth rate" or the
like. Perhaps a better term would be "realized population multiplier".
Similarly r(t)= log(lambda(t)) is very poorly named the "intrinsic
population growth rate" since there is very little intrinsic about it. A
better term might be "realized per capita growth rate".

My questions are these:
1) I have almost given up over lambda (t), but the notation is tricky
since it is easily confused with lambdasub1 the dominant eigenvalue of a
population projection matrix. I would prefer to use R(t)=N(t+1)/N(t), an
older, more British convention. Rsub0 is the population multiplier per
generation. R is the multiplier per time year (or other time unit). Is
this still worth fighting over? Has lambda(t) won?

2) Why not call lambda(t) the "realized population multiplier" when it
comes from data, and the "population multiplier" when it arises in
theory. Wat the heck does "finite population growth rate" mean anyway?

3) Why not call r(t) "per capita growth rate"? Please can't we stop
calling it "intrinsic"? Maybe rsubm, the Malthusian parameter is
intrinsic, but certainly not r(t) which is affected by density
dependence, environmental stochasticity, age structure, demographic
stochasticity and dozens more.

Now please note that I am already ruling out Peter Turchin's definition
r(t) = log(N(t)/N(t-1), as creating too much confusion with everybody
else. And I don't even want to get started about Royama's definitions or
  the almost random notations used by mathematicians who dabble in
ecological theory. This is day-to-day ecological vocabulary that needs
to be consistent for pedagogical, conservation and even legal reasons.

Subject: Re: Return of R(t) versus lambda(t)

Charles and everyone,


I also use Molles, and I also prefer to start with discrete single
population- no age structyuire models. So I start with N(t+1) = R(t)
N(t) and treat R(t) as a variable that can be estimated from a time
series. I show them a real data time series. I also estimate r(t) =
log(R(t).

Then I point out that if r(t) is constant we get exponential growth N(t)
= N(0) exp(rt). Then we look at population doubling, examples from
frogs, humans etc.

After that I immediately plunge into Molles Chapter 10 on Age structure.
But I can now connect the r to the R0 using r=log(R0)/generation time.

And only after these linear models for population growth do I introduce
density dependence.

To be clear, I am willing to teach lambda(t) instead of R(t) since it is
so commonly done in conservation biology. But I wish the ecological
community would commit themselves to it (or to R(t) which I think more
advantageous). Sooner or later we will wish we had meaningful standard
terms and notations for the most obvious concepts.

Subject: Buffalo meat questions

I have a writer colleague who desperately (and quickly -- asap today)
needs some info on nutrition of buffalo meat, and also whether they ever
can transmit or carry diseases like mad cow (virus?). She thinks they
can't because they eat grain - is this correct? This is for an article
for "Low Carb Energy" magazine.

I know this may not be the best forum to ask but I figure maybe there's
a buffalo biologist on list or two. Feel free to forward!

Her name is Sharon Wren, and her email is swren1@msn.com  - you can
contact her directly.

Thanks!!

Subject: Recycled Nest Cameras

Hello Ecofriends

I'm writing you because I'm trying to pull together a research plan for
my upcoming field season and I think someone (maybe even YOU!) could
really help me out. I'm currently studying the effects of fire on the
demography of the Cape Sable seaside sparrow (Ammodramus maritimus
mirabilis), in Everglades National Park. Currently I'm trying to
identify the nest predators within my study area. I've devised a
methodology that I'm confident will work, using a combination of fake
nests, finch eggs, and 24 hour time-lapse video. The literature is full
of similar studies and my hope is that some of you have also used a
similar methodology in your own work. In fact, I'm hoping that somewhere
in the corner of your lab, there lies a heap of cameras and vcr's that
are just begging to be used in another field experiment. Unfortunately
for us to reach our required sample size, purchasing new equipment would
be entirely cost-prohibitive. So, I'm asking you if I can borrow or
purchase your working-condition video equipment in order to complete my
research. Terms and conditions are definitely negotiable, so please
don't hesitate to contact me and discuss the matter.
Specifically, I'm looking for miniature black-and-white (or color)
electronic-board cameras in waterproof housing with infrared
light-emitting diodes around the lens to produce cryptic illumination
for night-viewing. For time-lapse recording, I'm looking for either
DC-powered time-lapse vcr's, or some other comparable product, also with
a waterproof case. An interface box and portable monitor to check camera
placement would be ideal. Of course, if you can provide any part of this
equipment, that would be fantastic. Again, feel free to contact me to
discuss further.


Sincerest Regards

David

Subject: Seriously!: Textbook suggestions for biochemical ecology course

Well, it's been more than a week, and I've got zero responses about the
topic (except for two folks who are interested in hearing what others
have to say).

Is this no longer a topic of interest to ecologists?  I find that hard
to believe, with the continued strong body of papers on induced
defenses, etc...published in the journals.

Do most ecologists let chemists and/or biochemists teach this topic for
us?

What gives?

Any feedback appreciated!

Subject: Forest Ecology Field Technician Position; early May - mid to late
    Aug.         2004

JOB DESCRIPTION - We seek one highly motivated individual interested in
ecological field experience to fill our research assistant position from
early May to middle or late August 2004. Our USDA-Forest Service funded
research project investigates the extent to which herbivory, competition,
and seed predation alter tree regeneration, and consequently, successional
trajectories in northern hardwood forests. Specifically, we are examining
the role that herbivory by white-tailed deer (Odocoileus virginianus), the
direct competitive impact by the native invasive hay-scented fern
(Dennstaedtia punctilobula), and small-mammal seed- and seedling predation
interact to alter juvenile tree species composition in the understory.

Subject: Re: Seriously!: Textbook suggestions for biochemical ecology course

I've taught these sorts of courses a few times, typically as
an upper-level special topics or graduate seminar class.  I
typically rely on the primary literature because there are
no recent comprehensive titles in this area.  There are some
edited volumes that focus on particular aspects of chemical
ecology, like Induced Responses to Herbivory, Karban and
Baldwin, Univ. of Chicago Press, 1997, or The Ecology and
Evolution of Inducible Defenses, Tollrian and Harvell,
Princeton Univ. Press, 1999.  You would have to supplement
these books with the primary literature to round out the
course.

Good luck,

Don

This is not my area of expertise, so I don't know what books are available.
But specialized topics, usually offered only at the graduate level, are
often taught without a textbook, of course, so none may be available.  I do
remember years ago (ah, just found it on my shelf!) a text by Harborne,
_Introduction to Ecological Biochemistry_.  Publication date is 1982 from
Academic Press.  I don't know if there has been a more recent edition.

GIS & REMOTE SENSING FOR WILDLIFE MANAGERS USING THE NEW ESRI SOFTWARE ARCGI

An Introduction to the use of Geographic Information Systems &
Remote Sensing in Conservation and Wildlife Management
April 12-16, 2004

Increasingly, Geographic Information Systems (GIS) and Remote Sensing - the 
apping of features using imagery acquired either from an aircraft or a satel
ite - have become important tools for decision-making and the applied manage
ent of natural resources.  Many federal agencies and NGO's rely on GIS and s
tellite data for their work and are starting to produce their own spatial da
abases.  However, there are few training opportunities for wildlife managers
to learn the application of GIS in everyday management situations.  We are o
fering a course for wildlife managers that will provide hands-on experience 
or the collection of data, GIS analysis of the data, and map-making using th
 latest ESRI and ERDAS software.

PROGRAM DESCRIPTION
This short course will provide wildlife managers with a working knowledge ab
ut the application of Geographic Information Systems (GIS) and Remote Sensin
 to the monitoring and management of wildlife and forest vegetation.  Exerci
es in establishing locations with a Global Positioning System (GPS), data in
ut into a GIS, and spatial analysis techniques for GIS will provide hands-on
and real world experience during the course.  Based on examples about habita
 selection in songbirds and white-tailed deer, course participants will lear
 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 phot
graphy, and State Agency databases.

From: Jose Valdes <jvaldes@SFWMD.GOV>
Subject: Palynological Inquiry

Dear colleagues:

I am a geologist working on the sedimentology/geomorphology component of
the Kissimmee River Restoration Evaluation Project in south-central
Florida.  As part
of this work, a potential application of palynological techniques has
been suggested about which I would like to solicit input from those
among you with expertise in
this field.

To put the matter in context, here is as brief overview of the
restoration project.  Between 1962 and 1971, the  meandering Kissimmee
River was channelized for
flood control and bisected by a 56-mile-long canal.  For about 40 years,
little or no flow occurred in remnant river channels, resulting in
vegetation encroachment
and deposition of organic matter on the river bed.  The restoration, the
first phase of which was completed in 1999, consists of backfilling the
canal, reconnecting the
remnant river channels, and reestablishing historic flows in the latter.
One of the restoration expectations is that accumulated organic deposits
will be flushed out of
remnant river channels, or covered with sand, and that the substrate of
the riverbed will return to (what is assumed to have been) predominantly
sand.

The dating of the layers cored from the river bottom is an issue of
ongoing debate.  It has been suggested that relative pollen counts could
offer a relatively
inexpensive way (vs. radiometric dating) of distinguishing among layers
deposited during the pre-channelization, post-channelization, and
post-restoration periods.
Although the historic (pre-channelization) floodplain flora, dominated
by broadleaf marsh/wet prairie species, transitioned into upland
pastures during the ~40-year
post-channelization period, there has not been a substantial change in
the suite of species present although the relative abundance of those
species changed (i.e.,
overall the same species are present but in different abundances).  In
the post-restoration phase (the last 3 years), a succession back to the
historic plant
communities is occurring.

So here are my questions:

(1) Is is feasible that relative pollen counts or some other
palynological technique could be applied to distinguishing at least
pre-channelization vs. post-chanelization
deposition?  Could one distinguish between pollen deposition due to
"pollen rain" vs. pollen from vegetation that decayed in situ?

(2) If we limited sampling to lithologically distinct layers, how much
of a subsample (i..e, interval thickness) would be needed from core
layers for palynological
analysis and would it be best to obtain such subsamples from just below
and above inter-layer contacts or randomly within layers?

(2) What would the cost per sample of such analysis? Can anyone refer me
to researchers who have done work of this kind or might be interested in
bidding on a
contract to do such work?  What commercial palynology labs in Florida or
elsewhere are available to do this type of analysis?

Thank you very much in advance for any feedback that you can provide.

From: Stephen Ellner <spe2@CORNELL.EDU>
Subject: R references etc.

As long as there's a flurry of interest here in R, let me add a couple of
things:

1. I teach my Theoretical Ecology course using R, and the lab notes can be
downloaded from my web page:
www.eeb.cornell.edu/Ellner/TheoreticalEcology/RIntro.pdf
The notes teach R from scratch with an emphasis on simulation and
programming, and complement documents like SimpleR that emphasize
statistics.

1. A recent post mentioned my old review of R in the ESA bulletin. A lot
has changed since then. Notably, there is now a generalized additive models
function (written by ecologist Simon Wood) that is much better than the one
in Splus, and the speed difference between R and Matlab has been overcome.
For some tasks where you would expect Matlab to shine (e.g. iterating a
large matrix model) R is actually faster, sometimes by a lot.

"Barnes, B.V., D.R. Zak, S.R. Denton, and S.H. Spurr 1998.  4th ed.  John
Wiley & Sons.  NY.
It emphasizes the ecosystem concept and an ecosystem approach to forest
ecology.  The chapter 21 on landscape ecology has sections about the PNW as
well as various other examples in the book.   It has lots of references! "

"Possibly dave perrys book, forest ecosystems.  somewhat less clinical than
Barnes it draws examples from tropical to boreal latitudes, emphasizing
forest structure and other forest organism groups in addition to trees.
There is also relevant material in franklin and dyrness's natural vegetation
of oregon and washington.  little's the dying of the trees might also
interest students as it documents how soil acidification, ozone, fungi, and
other factors have altered u.s. forest structure.

while your emphasis is pacific northwest forests another book I like very
much for its approach to forest analysis is 'tropical forest ecology' by
leigh of the smithsonian.  this book does a good job, for example, of
explaining leaf organization and divergence angle.

I cannot recommend either of kimmins earlier books.  while kimmins claims to
be balanced his pro forestry philosophy underlies the books structure and
some sections are logically questionable.  for example, his treatment of
plant alleochemicals, and his conclusion in earlier books that short
rotations increase or maintain carbon sequestration relative to old forests
is simply inaccurate (except in special cases).  ive not seen his new book
so possibly these sections have been corrected."

"I am using Barnes et al. (1998) book in my
undergraduate forest ecology course and I am very
satisfied with it. Contrary to Kimmins' book, it
concentrates on forest ecology and it covers many
aspects of forest ecosystems. I believe this is the
best book for biology students. If I were teaching to
forest engeneer students, I would reconsider very
seriously Kimmins' book. Please note that Kimmins
publishes a new book for the 2004 spring term."

"Kimmins J. P. 2004. Forest ecology: a foundation for sustainable
management. 3rd edition. Prentice Hall, Upper Saddle River, NJ."

"I'd recommend both of these texts:

Kimmins, J.P.  1997.  Forest ecology.  2nd ed.  Prentice Hall, Upper
Saddle River, NJ.
Barnes, B.V., Zak, D.R., Denton, S.R., and Spurr, S.H.  1998.  Forest
ecology.  4th ed.  John Wiley & Sons, New York.

For labs, the following general ecology field methods book is pretty good:

Brower, Zar & von Ende.  1998.  Field & laboratory methods for
general ecology.  4th ed.  WCB/McGraw-Hill, Boston.

Also check out ESA resources <http://www.esa.org/education/>,
especially Teaching Issues & Experiments in Ecology (TIEE) at
<http://www.ecoed.net/tiee/>."

""Forest Ecology" by Barnes, Zak, Denton, and Spurr is an excellent textbook
that
was revised in 1999 or 2000.  Burt Barnes was my Forest Ecology professor at
Michigan and Don Zak was my Soils professor; both excellent ecologist with a
substantial research and publication record.  Both are from the Great Lakes
Basin, so the methodology and examples in the book may be more suited to mid
western deciduous forests than northwest pine/fir ecosystems, but the
general principles should still hold true.  Anyway, that is my
recommendation.  It would be worth while for you to get ahold of a copy and
check it out for yourself."

"Readings were drawn from a number of scattered sources rather than a
textbook. For text-requiring issues (like forest soils), we readexerpts from
Forest Ecosystems, by David A. Perry (of Oregon State) (about $55 from Johns
Hopkins Press, 2001?). I like this book, and it is very relevant to your
region and to the sorts of issues (e..g., nutrient cycling) that are
important at the Canopy project. Alternative potential texts worth looking
into: Barnes, B.V. Forest Ecology 4th ed. (1998, John Wiley); Kimmins, J.P.

"We have a web-based resource that may be of use in your course. It is
called the Pacific Northwest Assessment and is available at:

<http://www.consbio.org/cbi/pacnw_assess/assess-main.htm>

It is organized by ecoregion with detailed reports for each of the 41
ecoregions in the area from Alaska down to northern California."

"One of the books is also used in the junior level ecology class - I covered
~half the book, and the ecology class covered the other half.  This book is
"Forest Ecology, 4th Edition" by BV Barnes, DR Zak, SR Denton, and SH Spurr.
I think it is a really good book to tie everything together from plant
physiology to landscape ecology.
But, my students found it to be "hard to understand".  Still, as a
reference, I like it, and I didn't think it was too hard to understand.  The
book I used this past fall is "Terrestrial Ecosystems, 2nd Edition" by JD
Aber and JM Melillo.  This book is easier to understand, but covers material
in less depth.  It didn't work well for my class as I focus on tree
physiology, but it has lots of ecology with examples from around the world.
I think both of them could be good references for your class."

"Depending on how far north you want to go, a great and very comprehensive
resource is the "Katchemak Bay Ecological Characterization" at:

<http://www.habitat.adfg.state.ak.us/geninfo/kbrr/coolkbayinfo/kbec_cd/ht
l/
welcome.htm>

The site goes well beyond forest ecology, and really gives a detailed and
integrated account of the from a very detailed perspective.  Lots of great
learning resources here.  Check it out."

"I found the following book quite useful when I took a Forest Ecology course
at Western Washington University, taught by David Wallin
(http://www.ac.wwu.edu/~wallin/).  The link for his Forest Ecolgy /
Terrestrial Ecology syllabus appears to be down, but it would be worthwhile
to contact him for a copy of the syllabus or textbook recommendations.  He
has taught this class for several years and would also have good insights as
to what are successful and appropriate field labs within PNW forests.


While I am sure that you have a good set of ideas concerning the concepts to
incorporate into your labs, here are a few ideas that I have from my
experience (a few years ago) as an upper-level science nerd of an
undergraduate in the PNW:
1.  Introduction to some of the tools used to measure various attributes of
forest ecology in the PNW.  This could involve students learning how to use
things like DBH tapes and stem corers - then collecting and analyzing the
data with respect to larger issues or datasets (for one lab we compared stem
radial growth to measures of local climate for mountain hemlocks on Mt.
Baker).
2.  Exploration of how historical land use and landscape processes interact
with site-level forest ecological dynamics (I am a landscape ecologist with
a penchant for interactions with land use dynamics at present, hence  the
bias).  Off the top of my head, I remember doing a 3-lab comparison of
forest structure and carbon storage between an old growth and a young
even-aged stand (2 labs in field, 1 in computer lab doing quantitative
analyses) - this could be appropriate for your class, as I seem to remember
an old growth stand not too far from your area, and even-aged stands are
easy to find.  A few labs that draw together issues surrounding PNW forests
as carbon storage areas - compared to the carbon output of a typical
automobile during 1 year of typical use - would be especially pertinent
considering the intensity of research and debate within this topic at
present.  There are some very interesting interactions with other landscape
processes besides harvest that you could certainly explore in that area,
including things like successional dynamics with respect to fire or debris
flow.
3.  Cross-ecosystem interactions, such as the interaction between forest
structure and salminoid habitat.  For example, it would be interesting to
explore relationships between forest structure & stream
temperature/nutrient-loading/CWD-loading.
4.  Forest structural dynamics and interations with plant/animal population
and metapopulation dynamics.

Here's the book reference:
Waring, R.H. and S.W. Running.  1998.  Forest Ecosystems: Analysis at
Multiple Scales.  San Diego, CA: Academic Press."

"as I'm sure you'll hear, Kimmins "Forest Ecology" has been the
standard in the field.  I've liked it for its emphasis on the ecosystem
approach.  I have loved using Jon Luoma's THe Hidden Forest", about the
research at H.J. Andrews, as a supplementary reading.  My students enjoy it
for the insight it gives them into what drives researchers in ecology, and
how ecosystem ecologists think.  It is out of print, but my bookstore was
able to find used copies.  If you want to expand your approach a little,
Chapin et al's Principles of Terrestrial Ecosystem Ecology is good and
current.

Labs are hard - folks usually end up designing things that work in their own
area.  I use a decomposition study - have the students set out litterbags in
the forest during their first lab, and collect them near the end of the
semester.  I have leaves collected beforehand ( senessed (can't spell)
leaves) and I have the bags already made.  They set them out in a pine and a
hardwood system and compare the amount of decomp at the end of the semester.
You could also use two different species - maybe a maple and a conifer and
compare their rates of decomp.

If you know anything about microarthropods, you could extract the
litterbags for microarths or take soil cores from those sites, and compare
the mites, collembola, etc from the two sites and encourage the students to
learn  about the roles of microarthropods in decomposition.

If you have a forest where you can set up dendrometer bands, you could do
that as a lab exercise and have future classes take readings and compare the
data to earlier classes.  ETc  Also collect litterfall and weigh  it -
giving data on productivity.

There are two important processes: decomposition and productivity.  If you
have access to a chemistry lab, you might try nutrient cycling - collect
stream flow and compare nutrients to those in local precipitation.  Or in
the soil samples from your different forest communities.  etc."

"Kimmins' Forest Ecology is absolutely the best basic reference for the PNW.
I used it primarily, but supplemented it with Perry's Forest Ecosystems and
Waring and Schlessinger Forest Ecosystems - Concepts and Management. Because
Kimmins is a tough read for undergrads, you may want to provide a reading
guide for the chapters.  Another less challenging textbook is Terrestrial
Plant Ecology by Barbour, Burk, and Pitts.  I often used this book as a
supplement (especially graphics) for lecture material - sometimes I needed
aids to simplification.  This textbook however lacks the PNW anchoring the
other books provide.

Of course there are many good papers to supplement an ecology class reading
list, but I always found such a challenge in covering ecology in a ten week
term, that I frequently relied on chapters in the book for much of the
reading, and supplemented lectures with info from journal articles.

A fascinating paper for many students was Distinctive Features of the
Northwestern Coniferous Forest: Development, Structure, and Function by
Franklin and Waring 1979.   In Forests: Fresh perspectives from ecosystem
analysis, R.H. Waring, ed. pp. 59-86.  I think students learned more from
that one paper than many of their other assignments."

"I am a big fan of "Forest Ecology" by JP Kimmins.  The Rainforests of Home
(edited by Schoonmaker) is also excellent and more focused on the forests
west of the Cascade Crest in Canada and the US.  You can supplement with
Franklin and Dyrness (Natural Vegetation of Oregon and Washington), Plant
Association Guides from National Forests, Atlas of the Pacific Northwest
(author is Loy?), Silvics of Forest Trees (Forest Service publications
available on-line), Creating Forests for the 21st Century (edited by
Franklin and Kohm), Forest Stand Dynamics by Oliver and Larson.
As for field-oriented labs, a transect across the Cascade crest is fairly
standard.  Successional sequences in different vegetation communities -
after fire, after logging, after volcanic disturbance, after windthrow,
after insect/disease and the differences and similarities among those
disturbances and their effects.  Measurement of common forest indicators -
relative density of trees, canopy closure, light transmission into the
understory, leaf area index, snags, downed wood, tree size distribution,
etc. in different forests.    "
"Personally, I'm fond of J.P. Kimmins text, "Forest Ecology" (ISBN
0130662585).  His examples are more often related to the PNW than others
I've come across.  He's bright and I believe very objective about his
science, but he's not shy of the idea of using forests to meet human needs."

The Fish Lake Biological Program in Michigan is offering a new,
one-week course called Herpetology for Teachers, which is designed for
in-service science teachers and science-education students. Students
will explore the world of reptiles and amphibians -- in the places
where they live. Field sessions predominate this course, so students
will spend considerable time outdoors exploring the hundreds of acres
of lakes, wetlands, forests and meadows of the Fish Lake grounds and
adjacent state game area, and conducting team field projects. At the
Fish Lake site, students will spend some time in lectures (which are
punctuated with videos of field herpetologists in action and current
research findings) and doing labwork to enhance their understanding of
the animals we will see in the field. The course also features several
field trips to sites of special interest where students can find some
of Michigan's less common amphibians and reptiles.=20

A dormitory and cafeteria are available for students who wish those
services. The Fish Lake biological station is located in Lapeer, Mich.,
about 60 miles north of Detroit.

For information about the course, which is offered through Wayne State
University, see http://bio.wayne.edu/fishlake/ or contact the

Hi all,

I will be teaching an introductory course in Ecology in the fall and I am
contemplating which text to use.  Ecology is offered at the sophmore level
and is required for all biology majors.  For a variety of reasons I prefer
the texts by Townsend et al (Essentials of Ecology) and Smith and Smith
(Ecology & Field Biology) but I am having a tougher time deciding which of
these two would be better.  I would appreciate hearing any comments that
fellow ecologgers may have on these two texts.

Subject: Position:  Forest Landscape Model Programmer

We are seeking a highly motivated programmer to assist with new development
and application of LANDIS, a forest landscape simulation model.  The
programmer will join the Forest Landscape Ecology Laboratory
(http://landscape.forest.wisc.edu/) at the University of
Wisconsin-Madison.  The start date is May 2004 and the project is funded
for a minimum of 1.5 years.

Complete information and application procedures are available at
http://www.ohr.wisc.edu/pvl/pv_046999.html

Requirements:
Degree in computer science or a degree in ecology with strong computer
programming experience.
Good written and verbal communication skills.
Ability to work with a team of scientists to develop a high quality product.
An interest in simulation modeling and forest ecology.
Familiarity with Unified Process Model or similar software development tools

Microsoft .NET and dll experience preferred.

Description:
The model, LANDIS-II, will be used to examine the effects of forest fires,
logging, and climate change on large forested landscapes throughout the
U.S. and world wide.  The programmer will work with scientists and staff at
the University of Wisconsin-Madison and the U.S. Forest Service.  The
programmer will assist scientists with model design, model testing, and
programming, using a standardized protocol for establishing program
requirements.  The programmer must be able to operate within a dynamic and
rigorous academic environment; good written and verbal communication skills
are a must.  An interest in scientific computing is highly
recommended.  Presentations at scientific meetings will be frequent.

Planned features of LANDIS-II will include:  a fully implemented object
oriented design and programming; designed to use dynamic linkable libraries
(dlls) from the ground up;  programmed in the Microsoft .NET framework,
allowing a variety of languages and platforms to be used and the ability to
utilize parallel processors, when available.  An intuitive model interface
will allow for rapid implementation by new users.  Publication of dlls and
dll interfaces on the web will allow other developers and users to
substitute alternative implementations of every model component.

    [ The following text is in the "iso-8859-1" character set. ]
    [ Your display is set for the "US-ASCII" character set.  ]
    [ Some characters may be displayed incorrectly. ]

Hello -- I'm studying birds along an urban to forest gradient, and have seve
al sample sites near noisy roads.  I am interested in determining whether th
 diversity and composition of birds I'm getting in my point counts reflect t
e actual diversity of birds, or rather the detectability of songs and calls 
elated to the level of ambient noise during the count.  I am aware that coun
s are often not conducted in noisy wind, for example, but this is not an opt
on near roads that always have traffic.  I have two main questions:

1) Is anyone aware of research efforts to determine the effects of ambient n
ise on bird detectability (by humans, not the ability of birds to hear each 
thers' vocalizations), or papers that tangentially address this in some way?
(That is, apart from "birds are hard to hear when it's noisy"); and

2) Potentially, I would be interested in purchasing a sound meter to enable 
easuring the decibel level at point counts and seeing whether repeated count
 at the same sites with different noise levels yield different estimates of 
iversity/composition.  Does anyone out there have experience using (inexpens
ve, say below $100) sound meters?  Ideally, I could find one that would repo
t average sound levels over a 10-min count period, as I'd prefer not to have
to take multiple readings during a survey.

Thanks for any advice.
