Cattle grazing and small mammals on the Sheldon National Wildlife Refuge, Nevada

We studied effects of cattle grazing on small mammal microhabitat and abundance in northwestern Nevada. Abundance, diversity, and microhabitat were compared between a 375-ha cattle exclosure and a deferred-rotation grazing allotment which had a three-year history of light to moderate use. No consistent differences were found in abundance, diversity, or microhabitat between the two areas.

[Book review] Birds of Malheur National Wildlife Refuge, Oregon

Although John Warham has worked for at least 40 years on procellariids, this book is much more than just a summary of a distinguished research career. It is a useful synthesis of the vast and often obscure literature on the more than 100 species of shearwaters, petrels, albatrosses, and fulmars that comprise the avian order with the widest range of body mass (19.5 g to 8.7 kg) and widest distribution, throughout the world's oceans, from the tropics to open leads in polar ice packs. The order's literary credentials are also impressive, with contributions from Dionysus (200 AD), St. Augustine, and Cole- ridge (not cited). Warham has also unearthed useful references from journals not examined by many ornithologists, such as Bocagiana , Il-Merill , and the Journal of the Manx Museum . He also appears to have done a good job of covering the Japanese-language literature.
