CLIMATE CHANGE IMPACTS: ECOSYSTEMS
"Assessing the Sensitivity of Canada's Ecosystems to Climatic
Change," B. Rizzo (State of Environ. Reporting, Environ. Can., Ottawa, Ont.
K1A OH3, Can.), E. Wiken, Clim. Change, 21(1), 37-55, May 1992.
Outlines potential ecological effects of a doubled CO2 climate, which are
applied to a classification model derived from the current ecological setting.
Results show major shifts in ecological boundaries and changes in the character
of Canada's broadly distributed ecosystems.
"Climate Scenarios for Alpine Regions: A Collaborative Effort
between ICALPE and ProClim," M. Beniston (ProClim--Swiss Nat. Clim. Prog.,
Hirschengraben 11, POB 7613, 3001 Bern, Switz.), M.F. Price, Environ.
Conserv., 18(4), 360-363, Winter 1991-92.
Describes FUTURALP, a project coordinated by the International Center for
Alpine Environments (ICALPE) within a program of the Commission of the European
Communities, aimed at understanding the foreseeable impacts of climate change on
"CO2LT: An Automated, Null-Balance System for Studying the Effects
of Elevated CO2 and Global Climate Change on Unmanaged Ecosystems," W.C.
Oechel (Dept. Biol., San Diego State Univ., San Diego CA 92182), G. Riechers et
al., Functional Ecol., 6(1), 86-100, 1992.
Describes a greenhouse system developed for long-term, in situ
greenhouse manipulation of atmospheric CO2 concentration and temperature for
intact plots of tussock tundra, and for measuring the instantaneous
ecosystem-level CO2 exchange rates within each of the plots under the treatments
imposed. Gives preliminary results.
"Human Impacts on Genetic Diversity in Forest Ecosystems," F.T.
Ledig (U.S. For. Serv. Exp. Sta., POB 245, Berkeley CA 94701), Oikos,
63(1), 87-108, Feb. 1992. A review of general impacts, which includes
some discussion of atmospheric pollution and global warming.
"Using Biotic Interactions to Forecast the Consequences of Global
Climate Change," A.M. Sugden, Trends Ecol. & Evol., 7(2),
35-36, Feb. 1992.
"Differential Utilization of Summer Rains by Desert Plants,"
J.R. Ehleringer (Dept. Biol., Univ. Utah, Salt Lake City UT 84112), S.L.
Phillips et al., Oecologia, 88(3), 430-434, 1991.
Seasonal changes in the hydrogen isotope ratios of xylem waters were
measured to determine the seasonal dependence of water use by plants in southern
Utah. Although precipitation there is currently evenly divided between winter
and summer, increased summer precipitation is predicted from anticipated climate
change. The differential responses of components within the plant community to
this increase are examined.
"Global Warming and Prairie Wetlands: Potential Consequences for
Waterfowl Habitat," K.A. Poiani (USFWS Nat. Ecol. Res. Ctr., Fort Collins
CO 80525), W.C. Johnson, Biosci., 41(9), 611-618, Oct. 1991.
Reviews wetland dynamics to establish the strong relationships among
climate, wetland hydrology, vegetation patterns and waterfowl habitat. Discusses
the potential effects of greenhouse warming and illustrates them using a
simulation model, which predicts a significant decline in habitat quality on
"Insects and Climate Change: Fossil Evidence from the Rocky
Mountains," S.A. Elias (Inst. Arctic & Alpine Res., Univ. Colorado,
Boulder CO 80309), ibid., 41(8), 552-559, Sep. 1991.
Describes some significant late glacial and Holocene changes that occurred
in the Rocky Mountains, presenting fossil data that summarize what is known
about regional insect responses to climate change in terms of species stability
and distribution. Insect species can move great distances to satisfy their
