Subject: Re: Rare or Threatened?
Hi,
I read this e-mail and I was thinking something.
A "rare" species could be : really rare, or very localized, or non collected
("uninteresting species" for many collectors), etc...
f.i. we know Aesalus neotropicalis (Coleoptera : Lucanidae) only from 1
trunk in Costa Rica, something like 30 specimens in collection. The species
have been searched in most of the national park. We can conclude that the
species is very localized.
A "endangered" species is something different. The main factor in this
concept is time. If the population is going down and can lead the species to
diseppear, than you have an "endangered" species. This population dynamic is
not available for most of insect species. And logically the species for
which the population dynamics are available are often economically important
species (mosquitoes, agricultural pests, etc...).
Can we concludes that Aesalus neotropicalis is "endangered" ? Perhaps during
the last centuries it has been so localized and has not disappear ? Than it
is not a desreasing population...
Sincerely,
JM

Dear Colleagues:
I wanted to bring your attention to a new international website and
corresponding Journal, "Ecological Indicators"
(http://www.ecologicalindicators.org. The website currently hosts
information about key works (texts) in the field of Ecological and
Environmental Indicators (click on each text graphic for more
information), as well as information on forthcoming symposia such as the
"3rd International Symposium on Environmental Indicators and Indices"
being held this October in Rome. Other links of interest (e.g., EPA's
EMAP program, Environment Canada's EMAN program) can also be found.
Hopefully, you will be interested in 1) reading more about the new
Journal, 2) taking my "poll" regarding your interest in indicators /
indices, 3) signing the guestbook so that we can learn more about YOUR
program(s) so that we can include this information in future website
updates, and 4) signing in to the EcoLinks FFA link which is one of the
only truly environmental FFAs I have seen (at least read the comments of
other programs readers have left there!).
My website is not supported financially (hence ".org") =E2=80=93 just put=

Subject: Effect of coliform bacteria on marine mammals
Dear Ecolog subscribers,
Does anyone have information, either anecdotally or in literature, about the
effect of coliform bacteria on marine mammals or higher level marine
carnivores? While it is widely noted that high levels of such
microorganisms can cause illness in humans-- and many beach closures across
the nation are a result of high fecal coliform counts-- few papers discuss
the impact on other marine organisms. Degraded water quality in general may
stress the immune systems of marine mammals and such, but what about
coliforms specifically?
Thanks so much for your comments,

Would an aqueous extract of rhubarb petiole ("stalk") be likely to contain

Subject: Re: Effect of coliform bacteria on marine mammals
Janna,
I can't specifically address the marine mammal issue, but coliforms
themselves are not necessarily all bad. They are used as indicator
organisms to test for fecal contamination of waters. Basically, if
coliform counts are high, there is a high probability that there may be
pathogenic bacteria in the water as well (such as Salmonella or Shigella
etc). That's why beaches are closed when the coliform count goes up
(sewage influx, too many poopy diapers, etc can cause this).
The term coliform encompasses a wide assortment of organisms that fit into
the general category of gram negative facultatively anaerobic rods, that
produce acid and gas from lactose within 24-48 hours. This includes E.
coli, most of which are harmless - only a handful of strains are dangerous.
Hope this helps.

that rhubarb, Rheum rhaponticum, may contain dangerous amounts of soluble

Subject: Postdoc positions
Please circulate:
******* 2 POSTDOC POSITIONS AVAILABLE ********
1) Postdoctoral research position in Orchard IPM
A postdoctoral position is available for a highly motivated individual to
explore the importance of landscape effects on the abundance and natural
control of orchard leafrollers, and the demography of sublethal effects of
pesticides on natural enemies. This study forms part of a regional research
program funded by USDA-IFAFS to extend the benefits of pheromone-based pest
management in western orchards.
The leafroller component, based on the obliquebanded leafroller in pear
orchards, will include field-based life table studies of leafroller
populations, and spatial analysis (GIS) of patterns of abundance of
leafrollers and natural enemies in relation to landscape characteristics.
The sublethal demography component will examine the influence of novel
pesticides on the demography of Chrysoperla carnea (Chrysopidae) and Mastrus
ridibundus (Ichneumonidae), as model natural enemies, through use of life
table response experiments and matrix models. The project provides an ideal
opportunity to conduct studies that will make important contributions to
insect ecology as well as facilitating the management of orchard pests
throughout the region.
The position is available from October 2001 ($30,888-33,696/year +
benefits), for 1 year initially with extension for up to 3 years. To
receive more information contact Nick Mills, Insect Biology and Center for
Biological Control, University of California, Berkeley
(nmills@nature.berkeley.edu; 510-642-1711). To apply, please submit a
curriculum vitae, a short description of research interests and experience,
relevant publications, and arrange to have three letters of recommendation
sent to Dr. Nick Mills, Insect Biology, Wellman Hall, University of
California, Berkeley, CA 94720-3112 by August 24, 2001. The position will
remain open until an appropriate candidate is found.
2) Postdoctoral research position in Insect Ecology and Biological Control
A postdoctoral position is available for a highly motivated individual to
explore the importance of size and host deprivation on the establishment of
introduced parasitoids in classical biological control. The study system is
Mastrus ridibundus (Hym.: Ichneumonidae), a gregarious ectoparasitoid that
has been imported from Central Asia and is currently being field released
for biological control of the codling moth in Californian fruit and nut
orchards.
The two-year project is funded by a USDA-NRI grant and will involve lab
studies of the influence of size and ovarian dynamics on the behavior and
performance of the parasitoid, and field studies of parasitoid fitness and
establishment success. This parasitoid is easily reared in the insectary
and is a promising candidate for biological control of codling moth in the
western region of the U.S. The project provides an ideal opportunity to
conduct studies that will make important contributions to insect ecology as

Subject: Fishers Alpha, statistical question
Hi,
I am revising a manuscript, and plan to use the below passage to justify my
lack of statistical analysis. I have Fisher's Alpha (for species diversity)
from 4 sites. Within each site, I have replication and subreplication (that
I will simplify for this discussion): 10 trees each site, and from each
tree, 3 subsamples. The software package calculates the index by running
through the subsamples. After three samples are run, the estimate is still
wildly off target. It takes a larger number of samples to narrow down to a
precise value for the index. Thus, it is not possible to get an estimate of
Fisher's Alpha for each of the ten trees based on their three subsamples. I
can get a good estimation for the site, but only if I pool all the
subsamples and draw from the same pool (thus, for each site, there are 30
replicates that are run through the iteration). Since the index for that
site is not based on the replication of the ten trees, I cannot run a
simple t-test or ANOVA based on a replication of ten. There really is no
replication to base a statistical test on. Right?
"Fisher's alpha was calculated using the EstimateS software package
(Colwell, 1997b). These values are obtained through an iterative process
that cannot produce independent, discrete values and reasonable variance
estimates on a per-tree basis with our levels of replication (3-6 trays per
tree). Site indices and error terms can be generated and compared
graphically, but this estimate is based on the pool of all subsamples from
that site. Diversity calculated in this manner cannot be compared
statistically within or among sites because there are no estimates of the
index for the replicates. "
Does anyone see problems with this statement? If so, how do I analyze these
data for differences among sites?
I am sorry if this is confusing, I am confused myself.

The easy bit is the publisher is Springer and the ISBN is 0-387-94322-6.
The difficulty I have with categories and lists is that- as a device for
informing managers- they emphasise what is known over what we are ignorant
about (and this list is usually bigger and more significant). I think we
need to be developing management tools that emphasise- not discount- what
is 'unknown'. This problem is especially acute for invertebrates but by no
means unique to them.
My rough rules of invertebrate conservation are that invertebrates are more
resilient to patch shrinkage than vertebrates- but more vulnerable to
patch-separation. Reserve designs that assume that vertebrate 'umbrella'
species will cover invertebrates are highly questionable. The peculiar
advantage of invertebrates is their ability to respond very quickly to
favourable management practices.
In NZ, few large invertebrates have survived the onslaught of predation
associated with rats. However, new species of _small_ invertebrates can
readily be found in incredibly tiny patches. If you've visited my
web-page, the falsescorpion depicted was found by a couple of native trees-
in a park- in the process of crawling up my leg. (Btw the photo dates back
to my MSc...before the current wonderful 3-D montage processes were

Subject: Ecolog-l: Re: Effect of coliform bacteria on marine mammals
I hope that someone will speak authoritatively (and cite the best
references) regarding whether or not "fecal coliform" is an adequate,
inferior, and/or misleading indicator of "safe levels" of the wide range of
contaminants that may be introduced into waters following sewage
discharges, storm events, etc. Please also address the issue of the various
processes involved in the reduction of "hazardous levels" of various
contaminants to points below some (arbitrarily or testable and verifiable)
point that is "safe" for people and other animals. In particular, please
mention the time fecal coliform levels (particularly E. coli) can remain at
"hazardous levels" compared to other bacteria, other harmful organisms, and
more or less common hazardous compounds. Please discuss also the
persistence (and reproduction) of such organisms and compounds (and their
alteration into "breakdown products" that are either "harmless" or even
more hazardous than the original).
In short, please discuss whether or not and to what extent fecal coliform
counts are irrelevant or even a misleading (if administratively convenient)
"scientific" means of sweeping the real problems under the rug. And just
what other indicators and forms of analysis are better and adequate for
assessing contamination. I would like to hear the opinions of
knowledgeable practitioners and researchers, references for specific
procedures, and examples of where they are
used. Bio-indicators? Bioassays? Cheap or expensive? Usable by folks
with minimal training or only by scientists or highly-trained technicians?
WT
The issue of marine mammals may be an excellent example of how much more
severe problems can go begging (heavy metals, complex compounds?) while a
well-intentioned public (and scientific community?) can be distracted with
straw-man publicity stunts, thus dissipating their energy, money and other
scarce resources. Is romantic attachment to "the charismatic species" a
dangerous delusion or an effective means of getting the public's attention
on broader issues and organisms that are not so charismatic? What percent
of the ecologist population falls into this category? Is the luxury of
obsessive romanticism one that "we" can afford, or is it, ironically, part
of the problem of mis-allocation of scarce resources and the energy of the
body politic?

Subject: Volunteer Positions in Alpine Chamois Project
VOLUNTEER POSITIONS IN A RESEARCH PROJECT WITH ALPINE CHAMOIS
A research project of the University of Bern in the Berner Oberland
(Switzerland) studies the behaviour of Alpine Chamois (Rupicapra rupicapra)
in its winter habitat on the Maennlichen Mt. above the town of Wengen (right
in the heart of the famous Jungfrau region of the Swiss Alps). Habitat use
and activity under different environmental conditions will be investigated
with radio-collared and marked individuals.
The main duty of the volunteers is the tracking of the radio-collard chamois
from permanent towers in Wengen. This will be carried out more or less
continuously during the field season. Volunteers will also take part in
other data sampling events, like behaviour observations, or recording of
environmental conditions.
Applicants are expected to have a general interest in biological and
conservation topics, but scientific knowledge is not necessary. The
willingness to work outdoor under harsh conditions (in winter and at night)
and in unregular intervals is required. Experience in high mountains is not
necessary. Volunteers have the opportunity to take part and actively work in
a current and conservation relevant research project. Lodging is provided in
our field station in Wengen, as well as project related travel expenses in
Switzerland.
Currently we accept volunteers for the following periods:
1) November 17th to December 8th, 2001
2) January 8th to February 5th, 2002
3) March 5th to March 26th, 2002
Applications are accepted until all the positions are filled.

The 98th Association of the American Geographers 2002 Annual Meeting
Los Angeles, California
March 19 - 23, 2002
Sponsored Session:
"Landscape Fragmentation and the Analysis of Land Use/Land Cover Change:
>From Pattern to Process."
Sponsored by the Spatial Analysis and Modeling, and the Remote Sensing
Specialty Groups
Session Description:
The relationship between human behavior and land cover change represents a
key research challenge for development projects, policy makers and
environmental organizations that aim to improve land management. For
identifying and mapping changes in land cover, remotely sensed data can
allow for the production of maps at greater spatial extents or over frequent
time steps than in situ field studies. Too often, however, the distinction
between land use and land cover is not well understood. Examining the
spatial patterns of such data can be a powerful means for linking pattern to
process, and linking land cover to land use.
Identifying and quantifying landscape fragmentation is a major focus in the
field of landscape ecology. Satellite imagery analysis is also an excellent
tool for the measurement of landscape patterns, because the spatially
explicit and extensive overview lends itself easily to studying the spatial
arrangement of land cover. Although much of the research analyzing
spatial patterns in the landscape has emphasized the impact of fragmentation
on biophysical factors (such as natural vegetation and a general decline in
the spatial extent and connectivity of wetlands, and wildlife habitat),
socioeconomic activity is also impacted by fragmentation. Increasing
landscape diversity has more potentially conflicting edges and opportunities
for externalities to positively or negatively affect neighboring land uses.
An overarching analysis of the causes, impact, and extent of land cover
change can make good use of these tools, to link pattern to process, and
thus to understand better the human dimensions of land cover change.
Papers will focus on using landscape metrics; integrating GIS,
socioeconomic, and remote sensing theory and methods to study landscape
pattern; and linking spatial pattern to land use process. Studies may focus
on issues in either Northern or Southern countries, tropical or temperate
forests, or other subjects of land cover change.
Please note: Starting this year, the AAG has changed its abstract submission
