21 Mar 2013 | Conference Proceedings | Contributor(s): Eric D. Salo, Kenneth F. Higgins, Bob D. Patton, Kristel K. Bakker, William T. Barker

We conducted studies in native prairie mixed-grass pastures in south~central North Dakota (U.S.A.) during 1989- 2003 to determine how different grazing intensities affected structural characteristics of vegetation, livestock production and the occurrence and density of grassland birds. Generally, …

Impacts of supplemental feeding on the nutritional ecology of black bears

21 Mar 2013 | Journal Articles | Contributor(s): Steven T. Partridge, Dale L. Nolte, Georg J. Ziegltrum, Charles T. Robbins

Black bear (Ursus americanus) damage to managed conifer stands during the spring in the U.S. Pacific Northwest is a continuing management concern. Because bear damage to managed conifers may reflect the limited availability of nutritious foods, supplemental feeding has been used to decrease damage. …

Use of injectable eugenol for euthanasia and anesthesia of American lobsters (homarus americanus) and similar species

21 Mar 2013 | Theses | Contributor(s): Carlton Huntsberger

Crustaceans are economically and ecologically significant, but current treatment and diagnostic protocols for crustacean health are limited. According to standards given by the American Veterinary Medical Association there are no current methods of euthanizing lobsters, nor are there effective …

Alligator nuisance control program in Texas: problem and process

20 Mar 2013 | Conference Proceedings | Contributor(s): Lee Ann Johnson, David S. Lobpries, Bruce G. Thompson

Following protection of the American alligator (Alligator mississippiensis) in Texas beginning in 1969, alligator numbers have increased rapidly (Patter 1981). Such population increases led to the federal reclassification of the species from Endangered to Threatened--Similarity of Appearance in …

Plastic visual barriers were ineffective at reducing recolonization rates of prarie dogs

20 Mar 2013 | Conference Proceedings | Contributor(s): Scott E. Hygnstrom

Two plastic visual barriers were ineffective in controlling expansion of 7 active black-tailed prairie dog (Cynomys ludovicianus) colonies and recolonization of 7 toxicant-treated sections of colonies. Barriers constructed with Sno-Strap, a 15.2- cm wide band of high-tensile polyethylene plastic, …

An ecosystem-based approach to slowing the synergistic effects of invasive species and climate change

20 Mar 2013 | Journal Articles | Contributor(s): David A. Strifling

Spring is springing earlier these days, an average of ten days earlier than it did just twenty years ago. This scientific phenomenon, called "spring creep," is often ascribed to climate change. Perhaps unsurprisingly, spring creep affects individual species differently. It is a boon to some and a …
