The role of natural history collections in documenting species declines
H.B. Shaffer, Robert N. Fisher, C. Davidson
1998, Trends in Ecology and Evolution (13) 27-30
Efforts to document the decline of extant populations require a historical record of previous occurrences. Natural history museums contain such information for most regions of the world, at least at a coarse spatial scale. Museum collections have been successfully used to analyse declines in a wide range of plants and...

Twenty species of helminths (9 trematodes, 9 nematodes, and 2 acanthocephalans), including 9 new host records, were collected from 40 bald eagles (Haliaeetus leucocephalus) from Florida. Intensities of infection were low and no lesions were attributed to the parasites. No species were considered specialists in bald eagles; 5 species were...

Timing and synchrony of parturition in Alaska caribou
Layne G. Adams, Bruce W. Dale
1998, Journal of Mammalogy (79) 287-294
Timing of parturition of caribou (Rangifer tarandus) varies within populations, but the relative influences of nutritional condition of females during the autumn breeding season and during gestation on that variation is not known. We determined timing of parturition of caribou in Denali National Park, Alaska, during 1984–1995, which had wide...
