“Life at
the Limits” Claremont Colleges Lecture Series Continues
Sept. 28
|
 |
Imagine living at an altitude of 6,000 meters where the
partial pressure of oxygen is less than half of that at sea
level, or, in the Great Salt Lake where the salt
concentration is hundreds of times that in tributaries of
the Amazon River. Some organisms not only tolerate such
conditions, they actually thrive under them.
“Life at the Limits: The Physiology of Extremophiles” is a
series of lectures by world-renowned experts on extreme
environments and the physiology and ecology of organisms
that inhabit them. The lectures are:
September 28—“Life in a Changing and Changeable
Environment: The Antarctic Peninsula” will be discussed
by Dr. Richard E. Lee, Jr., distinguished professor of
zoology at Miami University. Many animals go to
extraordinary lengths to avoid exposure to extreme cold. A
few however, “simply” freeze solid. Lee’s research focuses
on physiological and ecological mechanisms of freeze
tolerance and avoidance in temperate and polar insects,
dormancy and winter ecology of insects, frogs, and turtles,
and the use of freeze-tolerant organisms for biological
control. Reservations will be accepted beginning Sept. 18 at
2 p.m. and will be available until Sept. 24.
October 5—“Emperor Penguins: Residents of the 10th
Planet” is the subject of Dr. Gerald Kooyman’s lecture.
Kooyman is professor emeritus of biology at the Scripps
Institution of Oceanography at UC San Diego, has focused his
recent research on the effects of global climate change on
emperor penguins. His 40 years of studying emperor penguins
and Weddell seals in the Antarctic have dramatically changed
the way physiologists and behavioral ecologists think about
diving—an issue Kooyman will explore. Reservations will be
accepted beginning Sept. 25 at 2 p.m. and will be available
until Oct.1.
October 10—“Mono Lake: A Geological and Biological
Wonder” will be explored by Dr. Timothy Bradley,
professor of ecology and evolutionary biology at UC Irvine.
Bradley will discuss how Mono Lake, which is 2-3 times as
salty as sea water, supports an unusual and very restricted
suite of organisms that can tolerate the high salt levels.
One of his major areas of study is the characterization and
elucidation of the mechanisms of salt and water regulation
in saline-water insects. Reservations will be accepted
beginning Sept. 29 at 2 p.m. and will be available until
Oct. 6.
These lectures are co-sponsored by Pomona, Claremont
McKenna, Pitzer, Scripps and Harvey Mudd colleges and will
be held at the Marian Miner Cook Athenaeum (385 E. Eighth
Street, Claremont). Each evening starts with a reception at
5:30 p.m., dinner begins at 6 p.m., and the talks start at
6:45 p.m. For reservations, contact: Dr. Marion Preest (909)
607-8014 or
mpreest@jsd.claremont.edu or Jonathan Wright at (909)
621-8603 or
jonathan_wright@pomona.edu.
