Managed relocation is defined as the movement of species, populations, or genotypes to places outside the areas of their historical distributions to maintain biological diversity or ecosystem functioning with changing climate. It has been claimed that a major extinction event is under way and that climate change is increasing its severity. Projections indicating that climate change may drive substantial losses of biodiversity have compelled some scientists to suggest that traditional management strategies are insufficient. The managed relocation of species is a controversial management response to climate change. The published literature has emphasized biological concerns over difficult ethical, legal, and policy …

Conservation Implications When The Nest Predators Are Known, Frank Thompson, C.A. Ribic

USGS Northern Prairie Wildlife Research Center

Conservation and management of passerines has largely focused on habitat manipulation or restoration because the natural communities on which these birds depend have been destroyed and fragmented. However, productivity is another important aspect of avian conservation, and nest predation can be a large source of nesting mortality for passerines. Recent studies using video surveillance to identify nest predators allow researchers to start evaluating what methods could be used to mitigate nest predation to help passerines of conservation concern. From recent studies, we identified latitudinal and habitat-related patterns in the importance of predator groups that depredate passerine nests. We then reviewed …

Feral Swine Disturbance At Important Archaeological Sites, Richard M. Engeman, Kathy J. Couturier, Rodney K. Felix Jr., Michael L. Avery

USDA Wildlife Services: Staff Publications

Feral swine are well known as environmentally destructive invasive animals in many areas around the world, where they degrade native habitats, harm rare plant and animal species, damage agricultural interests, and spread disease. We provide the first quantification of their potential as agents of disturbance at archaeological sites. Our study was conducted in south-central Florida at Avon Park Air Force Range, a base comprising over 40,000 ha and containing many archaeological sites. To determine the identifiable prevalence of feral swine disturbance, we examined 36 sites registered with the Florida State Historic Preservation Office and also eligible for inclusion in the …

Genetic Population Substructure In Bison At Yellowstone National Park, Natalie D. Halbert, Peter J. P. Gogan, Philip W. Hedrick, Jacquelyn M. Wahl, James N. Derr

United States Geological Survey: Staff Publications

The Yellowstone National Park bison herd is 1 of only 2 populations known to have continually persisted on their current landscape since pre-Columbian times. Over the last century, the census size of this herd has fluctuated from around 100 individuals to over 3000 animals. Previous studies involving radiotelemetry, tooth wear, and parturition timing provide evidence of at least 2 distinct groups of bison within Yellowstone National Park. To better understand the biology of Yellowstone bison, we investigated the potential for limited gene flow across this population using multilocus Bayesian clustering analysis. Two genetically distinct and clearly defined subpopulations were identified …

Strategic Discussions For Nebraska: Opportunities For Nebraska -- Food Scarcity, Mary Garbacz

Department of Agricultural Leadership, Education, and Communication: Faculty Publications

Strategic Discussions for Nebraska is a program in the University of Nebraska-Lincoln Institute of Agriculture and Natural Resources that produces an annual publication called Opportunities for Nebraska, focusing on a different topic each year. The publication is produced in hard copy and also is available online at www.sdn.unl.edu.

The content for each publication is produced by UNL students enrolled in a Magazine Writing course each spring semester, taught by the SDN coordinator. Students conduct interviews with UNL researchers and write stories for inclusion in the publication. The interviews are captured on video and are edited into video montages, …
