This compilation catalogues the writings on the diverse vertebrate species within Colorado's boundaries beginning with the Escalante Expedition, which skirted the western slope a century before Colorado's statehood. Because of its geographical location-between East and West, North and Southwest, its altitudinal range of more than 11,000 feet, and its consequent variety of ecosystems from desert shrub to alpine tundra, Colorado ranks high among the fifty states for its variety of vertebrates. With such an abundance of these vertebrates, biologists and observant laypersons have had much to write about. This comprehensive bibliography is divided into major sections: General Natural History, Fishes, Amphibians, Reptiles, Birds and Mammals. Each taxonomic group has a general section, followed by listings at taxon levels down to alphabetically-arranged species. The bibliography is especially complete with respect to periodical literature through 1995. Colorado Vertebrate Zoology cites resources for studying both well-researched vertebrates and those needing more study.

Stands of aspen on the Gros Ventre elk winter range of northwestern Wyoming are suffering high mortality and are not regenerating satisfactorily. If the 1970 mortality rate (3.6 percent) continues, about a two-thirds reduction in the numbers of tree-sized aspen can be expected by year 2000. Collected evidence suggests that the mortality rate is unusually high because of a combination of pathogenic fungi, injurious insects, and physiological stress that follow bark wounding of tree trunks. Elk and possibly moose are suspected of causing most of these severe trunk injuries. Sooty bark canker, Cytospora canker, and stem-boring insects were the most common pests associated with tree mortality. The prospect for aspen on the elk winter range is especially critical because of the heavy impact of browsing and pests on aspen sprouts which prohibits natural replacement of the dying aspen overstory.

This is the authorized guide to the Maine Birding Trail, which opens in 2009. The book features more than 260 sites in Maine and includes bonus material on Campobello and Grand Manan islands. Unlike most guides, which emphasize species identification, this book highlights the sites themselves. Bird enthusiasts will count on it to lead them to the best birding locations in Maine and to list the species they will most likely find at each destination.

The Netherlands Antilles comprises three main islands off the coast ofnorthern Venezuela. These are Aruba, Curacao and Bonaire . They aremajor tourist destinations, especially popular with divers, and alsoattract many visitors from Holland and elsewhere. The colour plates are based on the bestselling Birds of Northern South America, but many new images have been painted specially for this book. The authoritative text highlights the key features needed to identify each species in the field, and the plates illustrate every distinct plumage and race. This will be the first evercomprehensive field guide dedicated to the birds of the region.

"Wildlife in a Changing World" presents an analysis of the 2008 IUCN Red List of Threatened Species. Beginning with an explanation of the IUCN Red List as a key conservation tool, it goes on to discuss the state of the world s species and provides the latest information on the patterns of species facing extinction in some of the most important ecosystems in the world, highlighting the reasons behind their declining status. Areas of focus in the report include: freshwater biodiversity, the status of the world s marine species, species susceptibility to climate change impacts, the Mediterranean biodiversity hot spot, and broadening the coverage of biodiversity assessments."
