Patterns in the species composition and richness of fish assemblages in northern Wisconsin lakes
Download1982
Fish assemblage structure, and factors and mechanisms appearing important in the ecological maintenance of these structures, were examined for 18 small lakes in northern Wisconsin during summer and winter. The study was focused around the following questions. Are there discrete, repeatable groups...

Unusual predation attempts of polar bears on ringed seals in the southern beaufort sea: Possible significance of changing spring ice conditions
Download2008
Richardson, E., Stirling, I., Thiemann, G.W., Derocher, A.E.
In April and May 2003 through 2006, unusually rough and rafted sea ice extended for several tens of kilometres offshore in the southeastern Beaufort Sea from about Atkinson Point to the Alaska border. Hunting success of polar bears (Ursus maritimus) seeking seals was low despite extensive...
