CLIMATE CHANGE IMPACTS: AQUATIC BIOLOGY

Item #d93jun68

"Expected Changes in the Wadden Sea Benthos in a Warmer World: Lessons from Periods with Mild Winters," J.J. Beukema (Neth. Inst. Sea Res., POB 59, 1790 AB den Burg, Neth.), Neth. J. Sea Res., 30, 73-79, Dec. 1992.

Based on changes observed in recent years in the macrozoobenthos of Wadden Sea tidal flats, mild winters lead to higher species richness and abundance. However, negative effects of mild winters include greater weight loss in bivalves during the winter, and low reproductive success in the following summer.

Item #d93jun69

"Predicting the Impact of Climate Change on the Spatial Patterns of Freshwater Fish Yield Capability in Eastern Canadian Lakes," C.K. Minns (Dept. Fish. & Oceans, Bayfield Inst., POB 5050, Burlington ON L7R 4A6, Can.), J.E. Moore, Clim. Change, 22(4), 327-346, Dec. 1992.

A regional model based on geographic data and equations of fish yield predicts substantial redistribution of fisheries under a GISS GCM climate change scenario. Without efforts to prevent temperature increases or substantial artificial redistribution of preferred species, Canadian freshwater fisheries would suffer major disruptions.

Item #d93jun70

"The Effect of Temperature on Larval Fishes," J.H.S. Blaxter (Scottish Marine Biol. Assoc., POB 3, Oban Argyll PA34 4AD, Scotland), Neth. J. Zool., 42(2-3), 336-357, 1992.

Discusses the influence of temperature on fish eggs and larvae from an autoecological viewpoint. Any increase of temperature from global warming would change the timing of ecological events such as the spring plankton outburst, influencing the match or mismatch of larvae with their food supply and their predators.

Item #d93jun71

Comment and reply on aquatic invertebrates and climate change, Can. J. Fish. Aquat. Sci., 49(6), 1274-1280, June 1992.

Item #d93jun72

"Satellite Monitoring of Optically Active Components of Inland Waters--An Essential Input to Regional Climate Change Impact Studies," R.P. Bukata (Natl. Water Res. Inst., POB 5050, Burlington ON L7R 4A6, Can.), J.H. Jerome et al., J. Great Lakes Res., 17(4), 470-478, 1991.

Illustrates with data some of the difficulties involved in using satellite observations to determine freshwater biological productivity, and the requirements for successful determinations on the regional and global scales.
