Reproductive data from the upper Midwest are meager for the striped skunk (Mephitis mephitis), a common North American carnivore. We provide data on some age-related reproductive attributes of 178 female striped skunks collected at 19 sites in eastcentral North Dakota and westcentral Minnesota in 1979–1981 and 1987–1991. Seventy-four percent of the females were 1 year old; 95% were...

The purpose of this extension bulletin is to assist public and private managers in locating, constructing, and managing islands to enhance nest success of waterfowl. The information is from studies by the Northern Prairie Wildlife Research Center, Jamestown, North Dakota, and information collected by biologists working at sites throughout the northern hemisphere.

Biotic response to the buildup of greenhouse gases in Earth's atmosphere is considerably more complex than an adjustment to changing temperature and precipitation. The fertilization effect carbon dioxide has on some plants, the impact UVB radiation has on health and productivity of organisms, and the resulting changes in competitive balance and trophic structure must also be considered...

This glossary provides standard definitions for many of the terms used in avian conservation biology. We compiled these definitions to assist communication among researchers, managers, and others involved in the Neotropical Migratory Bird Conservation Program, also known as Partners in Flight. We used existing glossaries and recent literature to prepare this glossary. The cited sources...

The purpose of this extension bulletin is to guide the management of nesting ducks on peninsulas on public and private lands. Managing peninsulas for ducks is a relatively new strategy that was developed in the grassland region of western North America. Information contained in this bulletin is primarily from studies conducted by biologists working at the Northern Prairie Wildlife...

During the past few decades numbers of some species of upland-nesting birds in North America have declined. Duck species such as mallard (Anas platyrhynchos), northern pintail (A. acuta) and blue-winged teal (A. discors) have declined since the early 1970s and have remained low since 1985 (Caithamer et al. 1993). Some grassland-dependent nonwaterfowl species also have declined since 1966...

Botulism is a food poisoning caused by the ingestion of the toxin produced by the bacterium Clostridium botulinum of any of six strains, designated A through F. The disease, as it occurs in epidemic proportion in wild birds, is most commonly of the C type, although outbreaks caused by type E botulism have been observed on the Great Lakes. C. botulinum is a widely distributed anaerobic...
