The Western Section of The Wildlife Society
2003 Annual Conference
February 27-March 1, 2003
Irvine, California
Featuring John Wiens, Kent Smith, and others
In the plenary session, preeminent wildlife professionals from several
different settings will describe their own career opportunities and
successes, as well as their challenges; limitations; and, possibly,
failures. In so doing, they will also provide guidance on the proper
boundaries of professional conduct in their particular field. The goal of
the plenary session is to bring together biologists working within the full
spectrum of wildlife biology to identify critical recurring issues of
professional conduct and ethics and foster among them greater understanding
and respect.

Hi Ecolog-L collegues
In my task (about of the convenience of the corridors into
natural and urban areas in a peripherical neighwood from
Barcelona), I'm doubts. The natural areas in the hinterland of
Barcelona has secondary communities, mainly of Pinus halepensis
(the potencial or primitive vegetation is, really, the tree of
Quercus ilex "Quercetum ilicis galloprovinciale"). In my study
related of the convenience of corridors I think sometimes about
with a particular case. In the coastal mediterranian area we
have one problem with an algae (Caulerpa taxifolia). It's an
invasive specie, original from caribean area (lost accidentally
from an aquarium of Monaco), what is very competent with
Posidonia oceanica (a marine fanerogame plant autocton in
Mediterranian area). We have an international programme to
monitor this algae because is invading and replace the original
habitat of Posidonia oceanica. The praderies of Posidonia are
very important environmentaly and commercially because the
migratorian fishes uses this habitat for less their eggs.
I'm "afraid" because my futures counseils in my work study
(about the corridors into urban and natural areas) can really
produce an ecological disaster for the potencial effect of an
invasive (generalist-exotic populations). What do you think
about? The "natural areas" can really support the exotic-
generalist species? What do you think about? Thanks avanced.
Sorry for my english.
Merry Christmas

Subject: federal science reports searchable online
The federal government has just launched a new website
(http://www.science.gov), allowing you to search for scientific reports
from 10 federal agencies online. See description below. It doesn't provide
abstracts, but it does let you know what's available and perhaps you can
track anything important through a local university library, if you have
that kind of access. Please pass this information on to other staff who
might be interested. I did a quick search for "wildlife corridors" and
"vernal pool ecology" and found 69 and 25 references, respectively. See
the references I found for each in the attachments. Hopefully this can be
another tool for you to keep up with current science.
**************
Science.gov contains reliable information resources selected by the
respective agencies as their best science information. Two major types
of information are included-selected authoritative science Web sites and
databases of technical reports, journal articles, conference
proceedings, and other published materials. (The specific content varies
by database.) The selected Web sites can be explored from the
science.gov homepage. The Web pages and the databases can be searched
individually or simultaneously from the search page.
Science.gov was developed by an interagency working group of 14
scientific and technical information organizations from 10 major science
agencies. Together these agencies make up the science.gov Alliance. A
number of these agencies are members of CENDI, which provides
administrative support and coordination for science.gov. These agencies
are committed to serving the information needs of the science-attentive
citizen, including science professionals, students and educators,
business people and entrepreneurs, and members of the public with an
interest in science. The Alliance and science.gov were formed to improve
and enhance access to information at science agency programs in response
to the April 2001 workshop on "Strengthening the Public Information
Infrastructure for Science."

Subject: News: Industrial Farming Impacts Pollinating Bees
http://ens-news.com/ens/dec2002/2002-12-20-09.asp
Industrial Farming Causes Trouble for Bees
PRINCETON, New Jersey, December 20, 2002 (ENS) - Intensive, industrial
scale farming may be damaging one of the very natural resources that
successful crops require: pollinating bees.
A study by scientists at Princeton University found that native bee
populations plummet as agricultural intensity goes up. In farms studied in
and around the Sacramento Valley in California, concentrated farming
appeared to reduce bee populations by eliminating natural habitats and
poisoning them with pesticides, the researchers reported.
U.S. farmers may not have noticed this effect because they achieve much of
their harvests with the help of imported bees rented from beekeepers.
These rented bees, however, are in decline because of disease and heavy
pesticide use.
The study, to be published this week in an online edition of the
"Proceedings of the National Academy of Sciences," found that native bees
are capable of doing a lot more pollinating than previously believed. But
it would take careful land use to take advantage of that capacity, the
researchers concluded, because current high density, pesticide dependent
agriculture cannot support native bees.
"This is a valuable service that we may actually be destroying through our
own land management practices," said Princeton ecologist Claire Kremen,
who co-wrote the study with Neal Williams, a postdoctoral researcher, and
Robbin Thorp of the University of California-Davis.
Suppressing the many species of native bees and relying on just a few
species of imported ones may be risky, said Kremen. Farmers who use
managed bee populations - that is, most commercial farmers - depend on
fewer than 11 species out of the 20,000 to 30,000 bee species worldwide.
Other researchers have estimated that $5 billion to $14 billion worth of
U.S. crops are pollinated by a single species of bee, the European honey
bee.
"Right now we are really very dependent on that species," said Kremen. "If
something happened to that species and we haven't developed other avenues,
we could really be in great difficulty."
The researchers spent two years examining watermelon farms located at
varying distances from oak woodlands and chaparral habitats that are
native to the Sacramento Valley. They also looked at land that was farmed
with pesticides and without pesticides. They focused on watermelon because
it requires a lot of pollen and multiple bee visits to produce marketable
fruit.
They found that native bee visits dropped off in the farms that were
distant from natural habitats and that used pesticides.
"We could then multiply the number of visits by the number of [pollen]
grains deposited per visit and sum that up for all the species and figure
out how much pollen the watermelon plants were receiving," said Kremen.
"We found that, where it still flourished, the native bee community could
be sufficient to provide the pollination service for the watermelon."
One interesting finding, said Kremen, was that the mix of native bees
providing the pollination was very different in the two years of the
study. In one year, a few strong pollinators accounted for most of it,
while in the other, many species contributed.
"That says something about the need for long term studies and also argues
for the need to maintain diversity," said Kremen.
