Subheadings within the Preface include: What is meant by the ecotoxicology of wild mammals? Rationale for the book, aim of the book, and structure of the book. Aspirations and chanllenges.

Fourteen captive and five free-ranging Minnesota gray wolves (Canis lupus) were tested for the presence of rabies virus neutralizing antibodies (RVNA) after vaccination with an inactivated canine rabies vaccine. Blood was collected from all wolves prior to vaccination and at 1 mo postvaccination (PV) and from all captive and three wild wolves at 3 mo PV. In addition, one free-ranging...

Collecting capture-recapture data under Pollock?s robust design provides an additional source of information on capture probability that can be used to provide less biased and more efficient estimates of population dynamics parameters. In addition, it can be used to estimate the probability of being available for capture, which in some cases (e.g., breeding proportion) has ecological...

This paper reviews recreation impacts, impact monitoring methods, and impact management strategies and actions for managing visitation in mountain environments.

Peterson (2001) used Genetic Algorithm for Rule-set Prediction (GARP) models to predict distribution patterns from Breeding Bird Survey (BBS) data. Evaluations of these models should consider inherent limitations of BBS data: (1) BBS methods may not sample species and habitats equally; (2) using BBS data for both model development and testing may overlook poor fit of some models; and (3)...

This paper rather informally tells of miscellaneous events that occurred during field work in Mexico, the Pacific Islands, and Virginia over the course of about 35 years.

Concentrations of particulate and total organic matter were measured in upper soil profiles at 26 sites as a potential means to identify toxic damage to soil ecosystems. Because soil organic matter plays a role in cycling nutrients, aerating soil, retaining water, and maintaining tilth, a significant reduction in organic matter content in a soil profile is not just evidence of a change...

Helicopter-mounted Forward Looking Infrared has mainly been used for large animal censuses. I examined the use of this instrument in locating bird carcasses in agricultural fields to improve current carcass searching techniques. Mallard (Arias platyrhynchos) and northern bobwhite quail (Colinus virginianus) carcasses were measured with an infrared thermometer immediately following death...

The ability of species to migrate and disperse is a trait that has interested ecologists for many years. Now that so many species and ecosystems face major environmental threats from habitat fragmentation and global climate change, the ability of species to adapt to these changes by dispersing, migrating, or moving between patches of habitat can be crucial to ensuring their survival...

The effect of ozonation of spent reactive dyebaths on both subsequent biological wastewater treatment systems and ultimate aquatic toxicity of effluents from the wastewater treatment plant was determined. Actual spent dyebaths from a textile plant were ozonated to remove color. The ozonated and untreated control dyebaths were diluted to produce wastewaters similar in dissolved solids...
