IMPACTS OF CLIMATE CHANGE: BIOLOGY
"Use of a Reservoir Water Quality Model to Simulate Global Climate
Change Effects on Fish Habitat," L.H. Chang (Environ. Sci. Div., Oak Ridge
Nat. Lab., POB 2008, Oak Ridge TN 37831), S.F. Railsback, R.T. Brown, Clim.
Change, 20(4), 277-296, Apr. 1992.
All six doubled-CO2 climate scenarios predicted by three GCMs indicate
overall declines in the available summer striped bass habitat in the
southeastern U.S., mainly because lake temperatures are expected to exceed
tolerance levels. Discusses the problems of predicting small-scale impacts from
large-scale grid models.
"Bacterial Growth in the Cold--Evidence for an Enhanced Substrate
Requirement," W.J. Wiebe (Dept. Microbiol., Univ. Georgia, Athens GA
30602), W.M. Sheldon, L.R. Pomeroy, Appl. Environ. Meteor., 58(1),
Growth responses and biovolume changes for four facultatively psychrophilic
bacterial isolates from Conception Bay, Newfoundland, and the Arctic Ocean were
examined at temperatures from -1.5° C to 35° C and various substrate
concentrations. Results have implications for food web structure and carbon flow
in cold waters, and for the effects of climate change.
"Potential Effects of Global Warming on Whitefish in Lake Constance,
Germany," E.A. Trippel (Biol. Sta., St. Andrews, N.B. E0G 2X0, Can.), R.
Eckmann, J. Hartmann, Ambio, 20(6), 226-231, Sep. 1991.
In the early stages of each climatic warming scenario examined, whitefish
abundance is predicted to increase. Results are sensitive to the timing of
temperature increases during April and May. Whitefish in shallow lakes may not
respond favorably to a warmer climate because of reduced oxygen enrichment of
"A 20-Year Record of Alpine Grasshopper Abundance, with
Interpretations for Climate Change," E.G. White (74 Toorak Ave.,
Christchurch 4, New Zealand), J.R. Sedcole, N.Z. J. Ecol., 15(2),
Potential effects of altered temperature, rainfall and rainday number are
considered in light of results from this New Zealand study. Concludes that flora
and fauna could eventually become depleted in alpine regions due to displacement
of grasshoppers to vegetation-scree margins.
"Chlorophyll a Distribution in Southern Benguela, Possible
Effects of Global Warming on Phytoplankton and Its Implications for Pelagic
Fish," P.C. Brown (Sea Fish. Res. Inst., Pvt. Bag X2, Rogge Bay, 8012 South
Africa), K.L. Cochrane, S. African J. Sci. (Suid-Afrikaanse Tydskrif
vir Wetenskap), 87(6), 233-242, June 1991.
Summarizes available chlorophyll data and statistical relationships between
chlorophyll and primary production off the south and west coast of South Africa.
Speculates on the implications of regional global warming, and proposes
monitoring of chlorophyll distributions.
