Subject: Croasdale Post-doc at Dartmouth
The Department of Biological Sciences at Dartmouth College seeks qualified
applicants for a Hannah T. Croasdale Postdoctoral Fellowship to begin in
January of 2004. The Croasdale Fellowships are two year, non-tenure track
positions with competitive salaries and research stipends. The successful
Fellow will teach undergraduate courses during two of the four terms in an
academic year (two courses per year total) and conduct postdoctoral
research, preferably in affiliation with an established laboratory in the
department. Candidates should be able to teach courses in Animal Behavior,
Vertebrate Biology, and Introduction to Ecology and Evolution.
Candidates must have a Ph.D. before 1 January 2004. Applicants should send
statements of research interests, teaching interests (including a
description of a potential course), curriculum vitae, representative
reprints, and the names and contact information for three references to
Croasdale Ecology Search, Department of Biological Sciences, Dartmouth
College, Hanover, New Hampshire 03755. Consideration of applications will
begin on 31August 2003. Dartmouth College is an Equal
Opportunity/Affirmative Action Employer.

Subject: Highly regarded book on aquatic optics, water clarity
"Colour and Clarity of Natural Waters: Science and Management of Optical
Water Quality" by R. J. Davies-Colley, W. N. Vant and D. G. Smith introduces
the basic concepts of aquatic optics and explains the relationships of the
different optical properties to the composition of the water and color and
clarity phenomena.
First published in 1993, the book became a word-of-mouth classic in the
field. It has just been brought back into print by The Blackburn Press,
making it again available to scholars, students, libraries and researchers
who would like to own or replace a copy of this invaluable book. It will be
of specific interest to water resource engineers, government agencies,
aquatic biologists, ecologists and students in environmental management and
water and wastewater courses.

The Blackburn Press is a relatively new publishing company, founded with the
mission of keeping in print and available for purchase at reasonable prices
book titles that larger publishers have lost interest in and have declared
to be "out of print." It specializes in scientific and technical books that
are classics in their field. (See www.blackburnpress.com).

Subject: Official definition of biomass allocation
Dear colleagues,
I am presently writing a paper on tall tree seedlings
(30 to 300 cm high) and I am struggling with the
meaning of two terms: biomass allocation and biomass
distribution. For me, biomass allocation is the annual
growth directed to each organ (foliage, stem, branches
and root) whereas biomass distribution is for example
the proportion of foliage mass (foliage mass/total
tree mass) at a given time. I took a look at the
literature to compare my definitions. It didn't help
at all because people use biomass allocation for both
meaning. Is there an official definition for biomass
allocation? If yes, which organisation wrote it and
how widely is it accepted among research journal?
Thank you in advance for your input,
Yves Claveau
P.S. I will summarize the results of this question if
people show interest.

Subject: Remote Still & Video Surveillance Systems
Good morning,
I am seeking information and advice for the purchase of remote camera
systems. We would like to document bear behavior, particularly sows with
cubs, in non-invasive barbed wire hair snag stations measuring 20'x20' and
with either dense or zero canopy cover.
My inquiry specifically regards:
1) Used remote camera systems currently available for rent or sale
2) Reviews of the various remote still camera systems and comparisons of
Buckshot, GameVu, Trailmaster, and DeerCam
3) Philosophies on the advantages and disadvantages of using a digital
camera for field operations (up to 2 weeks between visits)
4) Experiences with video surveillance
a) What we may lose in quality and dependability by choosing the less
expensive Trophyview over the Highlander or Trailmaster
b) Successful operations in the dark or areas with no canopy
c) The use of security surveillance cameras for wildlife applications
when a power source is available
5) Ideas for bearproof containers (in addition to ammo cans)
6) Success with infared illumination at night
To date, I have collected information from the manufacturers and comparison
charts from the following web sites:
http://texnat.tamu.edu/symposia/survey_of_cameras.pdf
http://www.jesseshuntingpage.com/cam-print.html
Any assistance would be greatly appreciated. Thank you...
Sincerely,

Subject: replies - literature on succession in natural forest gaps
hi all,
thanks to the people who replied to my request for literature on succession
n
forest tree-fall gaps - many requested that i post the replies to the list (

---------------------
there have been a lot of simulation models on this subject. In them, I am su
e
you will find references about natural systems, if you are more interested i
that than in the models themselves. Here is a quick list of some :
Botkin. 1993. Forest Dynamics: an Ecological Model. Oxford University Press.
Shugart. 1984. A theory of forest dynamics: the ecological implications of
forest succession models. Springer.
This is about conceptual models, not simulations:

and their role in community stability and organization. American Naturalist

plenty of literature on the topic in this Special Feature.
