Book Description
One egg from each of 440 clutches of eggs of 19 species of Alaskan seabirds collected in 1973-76 was analyzed for organochlorine residues. Both frequency of occurrence and concentration of residues in the eggs differed geographically and by species, apparently reflecting non-uniform distribution of organochlorines in the environment, dissimilar feeding habits and migration patterns of the species, or metabolic differences among the species.

Book Description
A sample of 365 stands of seeded nesting cover (mixtures of cool-season grasses and legumes) was studied in the glaciated prairie pothole region during 1977-79. Measurements of species composition, canopy cover, plant height, and visual obstruction values differed with stand age but only in a general way when results from over the entire region were pooled. Maximum values for plant height and visual obstruction occurred once per stand during the first 10 growing seasons. Although the year of maximum growth was variable and unpredictable, stands showed trends of degeneration in height and visual obstruction after the year of maximum growth.

Book Description
This bibliography, first compiled in 1970 and published in response to many requests for information on avian botulism, has been updated to include the literature published through 1980. In general only, articles dealing primarily with the avian disease are included, as opposed to those concerned with the various aspects of the biology of Clostridium botulinum, either type C or type E.A few exceptions, such as Bengtson's report of the first isolation and description of the type C organism, are included for their historical interest. Progress reports and other administrative documents not available for distribution on request are excluded, as are textbook accounts, which are generally summaries of work published elsewhere. This bibliography was a cooperative effort by the National Wildlife Laboratory, U.S. Fish and Wildlife Service, and the U.S. National Park Service, which provided partial funding for the work. Although there was an attempt to list every important reference, no claim to complete coverage of the published literature is made and the authors will be grateful to users of the bibliography who call attention to errors or omissions.
