Subject: 7th World Wilderness Congress
Greetings from the Leopold Institute! You are invited to take part in the
7th World Wilderness Congress, which will convene on the Eastern Cape of
South Africa in early November 2001. Attached are three different
formatted versions of our Call for Participation (hopefully, at least one
of these formats will work for you.) This year's Congress will offer an
excellent educational program, as well as "an extensive cultural program of
contemporary and traditional music and art, an international environmental
film competition, outdoor events under the African skies, and ample
opportunities (during pre- and post- Congress trips) to visit African
wildlands, communities, national parks, wilderness areas, and private
reserves." We are excited to once again be a part of this globally
important event and hope that you will be able to join us! Please feel
free to pass this on to any friends or colleagues, who might be interested
in attending. For more general WWC7 information check out their website at
www.worldwilderness.org. We look forward to hearing from you! Janet

It seems my comments about the semantics of preference vs. selection has met
with some criticism. As I mentioned in one of my previous e-mails, I
appreciate the fact that the difference was pointed out. I do, and have for
while understood this point, even if we can't all agree on the proper term.
have thoroughly enjoyed the debate that has ensued, yet I do wish that my
question had received such enthusiastic responses. I would like to once agai
thank everyone who did offer advice. I had originally intended to defend
myself and express my point of view on the matter, however I feel that many
compelling points have already been made. My opinion would simply be that, m
opinion. I hate to see a debate end, especially without resolve, but this
seems to be a topic with no real end in site. I do look forward to any
continuing debate on this topic, or any other that may arise.

Subject: Re: Global appetite for farmed fish devouring world's wild fish
supplies
NOTE: This is a serious question, not a prank. It is couched in stark
terms for clarity of contrast and brevity. It is what is called a zag-zig
question. This method of thinking is ancient, and has been used widely in
science, but is perhaps out of favor in ecology at the current time. I
offer this example in the hopes that it will find some (certainly not
universal) favor among ecologists. Of course it is intended only as one
example of the general direction that could be taken to be considered for
thoughtful consideration and study. Any levity is purely
coincidental. Please--no personal emails.
Honorable Forum and Karen:
What would happen if we fed them "mad cows" instead? (I'm tempted to add
"mad scientists" but I shall forego such levity (?) in the interest of
minimizing further threats to my person.) What was that about who's on the
top of the food chain again? But are cow bodies and human bodies fit food
for fish and fish welfare? What's more repugnant, the collapse of ocean
ecosystems or the preservation of the land-burial industry?
Respectfully submitted,
Wayne (zag-zig) Tyson

Subject: Re: Habitat selection/preference
Note: Some individuals may not want to read this post. See note at end of
message.
Honorable Forum:
DiBari's response is a welcome one, clear and specific. I do not intend to
imply anything about DiBari's response in the following. It seems sensible
to me as far as it goes, and I suspect that DiBari's ideas may go much
farther, but he is wisely choosing to keep his remarks simple and limited
to a minimal number of points.
Forgive me, but I do not think much in terms of individuals but of species
and populations. Perhaps that is the source of my confusion. I try hard
to think in terms of organisms, and to search for principles that may be
more reasonable than unreasonable, across individual, even species
lines. This does not mean that I wish to ignore subsets or to find
inferences and evidence in the case of individuals.
In Antarctica, there are, I understand, algae that live inside
rocks. Pretty rough habitat. Pretty limiting. A little too close to the
surface, no suitable habitat. A little too deep in the rock, no suitable
habitat. These organisms certainly "prefer" that very thin layer, and
certainly they "select" that habitat. As DiBari points out with admirable
simplicity, to do otherwise is not an option. (Perhaps there is an expert
in this organism (or group of organisms) out there that can illuminate this
better than I.)
Then there are organisms that have broader tolerance limits for habitat,
but still are "confined" to their genetically-determined
limitations. Yes. Individuals do screw up and die. But populations
define habitats and habitats define populations as part of a dynamic
process of resolution and interaction--Yes? No?

Subject: Re: habitat selection--more terms for?
Hi Dave.
I guess there do seem to be some issues here worth discussing. I am along f
r
the ride until the very last gasp.
Thanks first to an "off-list" commentator for pointing out that preference f
r
one habitat or diet item is always relative, and can only be measured in
relationship to something else (he didn't much like these terms either).
I suppose all terminology goes through a process of natural selection just a
anything else does. For what it is worth, I have no problem with the word
"affinity" as long as it is defined. What will ultimately matter will be th
way "affinity" or "preference" hypotheses are tested and quantified.
A few things seem worth discussing along those lines. It seems to me (and t
is
is what provoked my original comment) that field observations can show the r
nge
of potential habitats or diets used by an organism (selection, or choice).
However, field data will always have difficulties PREDICTING the way
physiological cues and the environment will interact to produce a behavior.
This will require an experimental setting of some type where the effect of
differing varibles can be isolted and treatments and controls are possible.
Obviously this becomes more difficult with larger terrestrial animals like
raptors, but most of the animals I study are relatively small and can be
confined in enclosures at natural densities. This demonstrates the obvious
eed
for all of us to study small animals, especially in aquatic systems (no, wai
,
first let me get a hard-money position, THEN you can all become aquatic
ecologists). ;)
The point is well taken that differing needs will require trade-offs and wil
be
stage-structured...varying through the development of the animal. Predation
threats balance against energetic profitability against access to mates agai
st
physiological tolerances. All of the caveats that apply to optimality theor
es
also apply here. There is no best of all possible worlds (to borrow again f
om
Voltaire's Panglossian Paradigm).
What does seem to exist, however, are heritable
preferences/affinities/whatever-you-call-thems that derive from the genes of
the
organism. As long as those can be repeatedly demonstrated, they seem to pro
ide
a handle for making predictions (as all applied ecologists eventually must)
about the outcomes of events in communities. Certainly the process is compl
x,
and requires humility, but I don't think we can responsibly give up on tryin
to
understand how communities work.
Best of luck with your paper,

Subject: Habitat preference/selection: lichen example
Wayne and others,
I'm also tired of this preference vs selection thread but I just want
to briefly add my comment: the theoretical point (dating back at
least to Fretwell as has been discussed) is it's all relative, and
the relativity changes fluidly depending on the ecological
circumstances.
Your endolithic lichen is an excellent example. Even a "organism"
(including this mutualism) with a very narrow, ultimately genetic,
habitat recognition and tolerance range may have, within this range,
more "preferred" (e.g., the center of the narrow zone) and less
"preferred" subranges (further outward or inward). ALL ELSE BEING
EQUAL (and this would most easily be documented experimentally), the
lichen prefers the center. If this is already occupied by
competitors (and let's ignore the semantic complications of any
clonal self-competition), however, available space in the center of
the tolerable range and therefore the habitat utility may decline
until a "selection" of the less "preferred" areas would be just as
good.
Although it's easier to understand this conceptual approach with the
lichen because of the relative simplicity of its habitat dimensions,
the same concepts apply to other organisms. The idea and measurement
of "preference" gets harder and harder in principle and practice
though because of the potential for interactions among habitat
factors as one increases the number under consideration. Still, it's
been a useful, generalizable, conceptual distinction within ecology.

Subject: Re: humpty dumpty and restoration
The comparison is cute but quite irrelevant. Ecological communities fall
(are pushed, etc.) apart all the time by disturbance, climate change,
invasions, local extirpations, etc. Not coincidentally they also possess
myriad pathways for reassembling themselves (the attribute that Humpty
Dumpty so tragically lacked), even with the local absence of a species that
was formerly present. Do they reassemble themselves into exactly their
pre-disturbance configuration? Of course not -- but then, that would also
be a naive view of restoration ecology, which also stresses structural and
functional attributes. This is why the field of disturbance ecology is so
profoundly relevant to restoration ecology. On even longer time frames one
might also look to vegetation responses to (and disequilibrium with)
climate change, as well as evolution for real models of restoration.

Ecologers,
As many of you know, there are indications that the new Administration =

National Science Foundation and the U.S. Geological Survey. A recent Wall =

intervening period, the numbers for various programs will be fleshed =
out--they appear to be a long way from being firmed up. However, it =

potentially weak numbers for the above agencies. =20
ESA members interested in playing an active role during the budget season =
(which runs from the unveiling of the President's budget to the start of =

editorials for local newspapers (please see tips below) and working with =
their congressional representatives both in writing and in personal =
meetings. To find out how, please visit ESA's online Policy Page =

Possibly the reason behind this discussion/debate is a perception that
preservation is somehow nobler than restoration; that once we create a
preserve we've met our goal and do not need to get involved in the
grunge-work of restoration. This perception may come from those of us
involved primarily in restoration as our unfair view of those involved
primarily in preservation. Perhaps it even harkens back to the bad old days

Subject: Field Assistant needed for cutthroat trout project
2 Field Assistants needed to help with field sampling for a genetics study
of Lahontan cutthroat trout. Field site is in the Jarbidge mountains, NE
Nevada. July through mid-August. Work is strenuous, requiring a good deal
of hiking and backpacking carrying heavy equipment (electrofishers).
Sampling entails setting up block nets on streams, performing 3-pass
electrofishing of sites, and taking various measurements and small fin
clips from fish. Ten streams will be sampled at multiple sites in upper
and lower reaches. Higher elevation field sites are in a Wilderness Area,
lower sites are on BLM land and impacted by cattle. Climate is dry, HOT
during the day, and cold at night. We will be camping (access by truck)
most of the time, with one or two back-pack trips to upper sites.
Experience with fish not required but preferred. Vehicles and field
equipment supplied, but need own camping equipment. Pay: $900-1100/month,
depending on experience. If interested, please send cover letter and
resume with 3 references by March 30th. Sending electronic letters/resumes
is fine as long as they don't come with viruses!

Subject: Re: habitat selection
> Habitat preference...habitat selection...
This distinction is similar to the distinction between fundamental and
realized niches, is it not?
Habitat preference is analogous to defining an organism's fundamental
niche, i.e. the sites and environmental conditions where it would maximize
it's reproductive success in the absence of any intra- or interspecific
competition. There is some ambiguity here, since the range
of physiological tolerance is rather larger than the optimum environment.
This is largely a theoretical concept, since there is almost always
competition in the real world. Habitat preference is typically defined by
raising organisms in controlled conditions over a range of environmental
conditions and then extrapolating to the real world by geographic analysis
of species occurrences.
Habitat selection is analogous to defining an organism's realized niche,
i.e. where it actually ends up trying to eke out an existence after
finding stiff competition from members of its own and maybe a host of
other species for all the really choice spots. These sites will be
somewhere within the physiological tolerance range of the species (by
definition), but often not right at the optimum. Habitat selection can be
directly observed in the field.
My (less than exhaustive) literature reviews suggest that people working
on animals have done more with these ideas, but they apply equally well to
studies of plants although the methods of selection are quite different.
The distinction is important with regards to restoration because
restorationists want to put things back in something approaching optimal
sites, not marginal ones, but all we usually have to go on when deciding
what the optimal might be (the preferred habitats) are observations of
where the things actually are found (the selected habitats).
The restorationist's job is further complicated by the prospect of climate
change because now we've not only got to figure out where many species
would prefer to be now, but to predict where those conditions will occur
in the future and somehow make it possible for the species to follow their
preferred niches across a fragmented landscape as rapid climate change
plays out.

Subject: Fwd: Re: student inquiry
Colleagues,
I received an email from a university student here in California who is
pursuing a senior project in association with CalTrans, the California
Department of Transportation. CalTrans is interested in knowing of any
effects of solid concrete medians vs. three-beam steel medians on animal
movement. In a nutshell, the concrete medians are easier to install and
therefore cheaper, but they are willing to listen to arguments -- if they
exist -- on the relative influence of these two styles. I am not aware of
any literature on this, so thought I would toss this out to the general
audience. Any citations to standard or gray literature would be most
greatly appreciated.
If needed I can post a summary to the server.

Hi Robert and Forum,
I think this is an excellent statement. Maybe one to
conclude this thread. However, we must be careful to
keep habitat and niche from becoming synomonous. At
least in my humble opinion. Maybe we could explore "
selected niche" as opposed to "prefered niche"
Best wishes to all,

Subject: calculating transition probabilities
I'm looking for a program to calculate transition probabilities. This is for
a long-term data set that follows individual plants in the population over a
15+ year period and I would like to calculate the transition probabilities
(seedling - juvenile - etc...). I think this could be done in Excel, but I'm
open to other suggestions. Sincerely, Danny
