IMPACTS ON THE HYDROLOGICAL CYCLE, FRESHWATER ECOSYSTEMS
These topics are the respective themes of the July and September issues of
GeoJournal (Kluwer Academic Publishers).
In GeoJournal, 27(3), July 1992:
"The Nature of Short-Periodic Climate Variation and Its Relation with
Water Exchange," V.I. Ferronsky (Russian Acad. Sci., Water Problems Inst.,
13/3 Sadovaya-Chernogriazskaya St., 103064 Moscow, Russia), 237-242. Examines
the effects of solar energy flux variation in the annual cycle.
"Marine Terraces as Indicators of Global Geoidal and Hydrological
Changes," Yu.A. Tarakanov (Russian Acad. Sci., Earth Phys. Inst., 10
Bolshaya Gruzinskaya, Moscow, Russia), R.K. Klige, A.O. Selivanov, 243-246.
Spatial analysis of marine terrace elevations from 40-30 thousand years BP was
used to indicate past water regimes.
"Incorporation of Hydrologic Cycle Elements into the Dynamic-Stochastic
Climate Model," S.G. Dobrovolsky (Russian Acad. Sci., Water Problems Inst.,
13/3 Sadovaya-Chernogryazskaya St., 103064 Moscow, Russia), O.O. Rybak, 247-254.
"Continental Cloudiness Changes This Century," A.
Henderson-Sellers (Clim. Impacts Ctr., Macquarie Univ., N. Ryde, NSW 2109,
Australia), 255-262. Based on data from 1900 to 1985, total cloud amount in two
of four continents examined shows a statistically significant increase.
"The Global Hydrologic Cycle and Its Continental Links," K.K.
Edelstein (Moscow State Univ., Faculty of Geog., Lengory, 119899 Moscow,
Russia), 263-268. Examines how the global cycle is reflected in river flow and
the chemical composition of surface waters.
"Trends in the Long-Term Variability of Groundwater Discharge,"
V.S. Kovalevsky (Russian Acad. Sci., Water Problems Inst., 13/3
Sadovaya-Chernogryazskaya St., 103064 Moscow, Russia), 269-274. Predicts that
global warming could increase groundwater recharge in the USSR 10%-40% in the
beginning of the next century, resulting in improved water supply but also
negative ecological impacts of waterlogging and flooding, especially in cities
"Fluctuation of Atmospheric Precipitation in Europe," R. Brázdil
(Dept. Geog., Masaryk Univ., Kotlárská 2, Brno 611 37, Czech.),
275-291. Analyzes temporal and spatial characteristics of annual precipitation
fluctuations, and presents expected changes in global and European precipitation
for a doubling of CO2, based on the GISS and GFDL models.
"The Significance of Global Snow and Ice Cover for Global Change
Studies," R.G. Barry (CIRES, Univ. Colorado, Boulder CO 80309), 293-297.
The state of global monitoring of snow and ice conditions is adequate for some
variables but not for others. Describes recent trends and projected changes from
increased greenhouse gases.
"Changes in the Water Regime of the Caspian Sea," R.K. Klige
(Dept. Geog., Moscow State Univ., 119889 Moscow, Russia), 299-307. Attempts to
forecast the level of the Caspian Sea at the end of the twentieth century that
would result from possible climate changes, by examining historical,
paleogeomorphical and other data.
"Yearly Variations in Runoff as a Function of Precipitation Variations
for the East-European Plain," V.I. Shvejkina (Russian Acad. Sci., Water
Problems Inst., 13/3 Sadovaya-Chernogryazskaya St., 103064 Moscow, Russia),
GeoJournal, 28(1), Sep. 1992, contains papers from a
symposium on global warming and freshwater ecosystems, held during the XVII
Pacific Science Symposium of the Pacific Science Association (Honolulu,
Hawaii, May 1991):
"Tools for Assessing the Impact of Climate Change on Freshwater Fish
Populations," B.J. Shuter (Ontario Min. Environ., Box 5000, Maple, Ont. L6A
1S9, Can.), J.D. Meisner, 7-20. Examines methods such as bioenergetic models for
the growth of individual fish, thermal habitat models to assess impacts on
population abundance, and life cycle models to assess impacts on zoogeographic
distribution of species. Identifies required research on them.
"Assessing Potential Effects of Global Climate Change on Tropical
Freshwater Fishes," J.D. Meisner (ESSA Ltd., 9555 Yonge St., S. 308,
Richmond Hill, Ont. L4C 9M5, Can.), B.J. Shuter, 21-27. Initial assessments
should focus on changes to water quality variables in riverine environments at a
coarse resolution. A useful starting point would be comparative analysis of the
sensitivity of blackfishes and whitefishes to changes in habitat availability,
oxygen levels and dessication stress.
"Global Climate Change and Fish and Fisheries: What Might Happen in a
Temperate Oceanic Archipelago like New Zealand," R.M. McDowall (Min. Agric.
& Fish., POB 8324, Christchurch, N.Z.), 29-37. While expected changes will
be much more rapid than those from New Zealand's geological past, they are
unlikely to be perceived by the human population, and less extreme than present
problems such as deforestation, river impoundment and eutrophication.
"Prediction and Assessment of Potential Effects of Global Environmental
Change on Freshwater Sports Fish Habitat in British Columbia," T.G.
Northcote (Westwater Res. Ctr., Univ. British Columbia, Vancouver, B.C., V6T
1W5, Can.), 39-49. The high topographic relief and physiographic diversity of
British Columbia make impact predictions difficult. Both positive and negative
impacts are projected, and management policies discussed.
"Probable Consequences of Climate Change on Freshwater Production of
Adams River Sockeye Salmon (Oncorynchus nerka)," M.A. Henderson
(Dept. Fish. & Oceans, 555 W. Hastings St., Vancouver, B.C. V6B 5G3, Can.),
D.A. Levy, J.S. Stocker, 51-59. Information on the influence of temperature on
the thermal physiology, growth and survival of salmon, combined with projections
of temperature change for doubled CO2, show that the net effect over all
freshwater life history stages will be a reduction in the freshwater production.
"Predicted Effects of Climate Warming on the Commercial Culture of the
Channel Catfish, Ictalurus punctatus," R. McCauley (Dept. Biol.,
Laurier Univ., Waterloo, Ont. N2K 3C5, Can.), T. Beitinger, 61-66. Reviews
thermal requirements for growth and the role of air temperature and
precipitation in limiting the distribution of profitable fish farms, and
constructs a model for changes in this distribution in the U.S.
"Large Lakes of the World: A Global Science Opportunity," D.F.
Reid (NOAA Great Lakes Environ. Res. Lab., 2205 Commonwealth Blvd., Ann Arbor MI
48105), A.M. Beeton, 67-72. The large lakes of the world contain over 68% of the
fresh liquid surface water and are increasingly threatened by anthropogenic
influences including climate change. Proposes an organized, multinational
framework for the study of large lakes on a global scale, similar to programs
underway for the atmospheric and oceanic sciences.
"Ecological Studies on the Kerkini Reservoir (N-Greece)--I.
Morphometric, Hydrological, Physical and Chemical Features," A. Kamarianos
(Sch. Vet. Med., Aristotelian Univ. Thessaloniki, Univ. Box 404, 54006
Thessaloniki, Greece), X. Karamanlis et al., 73-80.
