Trans Fatty Acids Provide Evidence Of Anthropogenic Feeding By Black Bears, Gregory W. Thiemann, Randal S. Stahl, Sharon Baruch-Mordo, Stewart W. Breck Jan 2008

Trans Fatty Acids Provide Evidence Of Anthropogenic Feeding By Black Bears, Gregory W. Thiemann, Randal S. Stahl, Sharon Baruch-Mordo, Stewart W. Breck

Human–Wildlife Interactions

Bears (Ursus spp.) that become conditioned to anthropogenic food sources pose a risk to human safety and generally need to be relocated, rehabilitated, or destroyed. Identifying food-conditioned bears may be difficult if the animal is not captured or killed while immediately engaged in the nuisance behavior. Fatty acid signature analysis has been used to examine the dietary habits of bears and other carnivores and is based on the predictable incorporation of ingested fatty acids into the consumer’s fat stores. Unusual fatty acids that are available in only a few food types may be particularly useful dietary markers. In this …


Population Viability Analysis Of Monk Parakeets In The United States And Examination Of Alternative Management Strategies, Stephen Pruett-Jones, James R. Newman, Christian M. Newman, Michael L. Avery, James R. Lindsay Jan 2007

Population Viability Analysis Of Monk Parakeets In The United States And Examination Of Alternative Management Strategies, Stephen Pruett-Jones, James R. Newman, Christian M. Newman, Michael L. Avery, James R. Lindsay

Human–Wildlife Interactions

In the United States, monk parakeets (Myiopsitta monachus) are expanding their geographical distribution, and their overall population size is growing exponentially. Monk parakeets are causing widespread economic damage in the United States by nesting on utility structures, which leads to electrical fi res and power outages. Although few life history data are available for the species from North America, extensive data are available from the species’ native range in South America. Incorporating data from South America into the population viability analysis program VORTEX, we simulated population growth in United States monk parakeets to determine whether it is likely …


Best Management Practices For Aquatic Vegetation Management In Lakes, Joseph E. Morris, Richard D. Clayton Oct 2006

Best Management Practices For Aquatic Vegetation Management In Lakes, Joseph E. Morris, Richard D. Clayton

11th Triennial National Wildlife and Fisheries Extension Specialists Conference (2006)

Aquatic plants are an important component of well functioning lake ecosystems. Plant abundance is influenced by sediments, nutrients and water clarity. Given the dominance of agriculture in Iowa, nutrients and soil lost from “leaky” watersheds combine to create ideal habitat for growth of aquatic plants in lakes and ponds and hasten eutrophication. Under these conditions, plant growth can become a nuisance and reduce recreation, especially shoreline angling and boating. These nuisance growths present special problems to lake managers and those interested in lake-based recreation. Given the complexity of the aquatic vegetation often found in lakes, there is no one long-term …


Breaking Through The Food Plot Mentality, Christopher E. Moorman, Craig A. Harper, Christopher Deperno Oct 2006

Breaking Through The Food Plot Mentality, Christopher E. Moorman, Craig A. Harper, Christopher Deperno

11th Triennial National Wildlife and Fisheries Extension Specialists Conference (2006)

Landowners and other wildlife enthusiasts often desire instant gratification when attempting to attract wildlife to their properties. Advertisements distributed by television programs, outdoor publications, and conservation organizations have played a large part in creating the desire for a quick and easy fix. Landowners are erroneously led to believe food plots or plantings of nonnative shrubs and trees will raise the carrying capacity for target wildlife species, even though the typical privately-held property contains overstocked, high-graded timber, intensively maintained croplands, mowed roadsides and drainage ditches, fire-suppressed woodlands, and pastures vegetated with non-native grasses that provide no cover and poor-quality forage. In …


Managing Kentucky Fee Fishing Operations, Forrest Wynne Oct 2006

Managing Kentucky Fee Fishing Operations, Forrest Wynne

11th Triennial National Wildlife and Fisheries Extension Specialists Conference (2006)

Management strategies for operating fee fishing operations in Kentucky are described. Recommendations are given for stocking rates of catfish, hybrid bream, and trout; aeration, pond depth and shape, supplemental feeding, and other management considerations. Marketing considerations discussed include pricing, and amenities such as restrooms, fish-cleaning services, and concessions including rental or sale of tackle and supplies.


The Costs Of Birdstrikes To Commercial Aviation, John R. Allan, Alex P. Orosz Aug 2001

The Costs Of Birdstrikes To Commercial Aviation, John R. Allan, Alex P. Orosz

2001 Bird Strike Committee-USA/Canada, Third Joint Annual Meeting, Calgary, AB

Collisions between birds (and other wildlife) and aircraft are known to cause substantial losses to the aviation industry in terms of damage and delays every year. Techniques exist to control bird numbers on airfields and hence to reduce the numbers of wildlife strikes but they are applied at widely different levels from airport to airport. Some of this variation may be due to differing levels of strike risk at the different sites, but much of it is due to the unwillingness or inability of the airports concerned to invest in birdstrike prevention. Part of the reason for this reluctance to …


The Press And Citizen Participation: A Content Analysis, Lisa Pelstring, James Shanahan, Ben Perry Oct 1997

The Press And Citizen Participation: A Content Analysis, Lisa Pelstring, James Shanahan, Ben Perry

Eighth Eastern Wildlife Damage Management Conference (1997)

We conducted a content analysis of regional New York State newspapers to assess media coverage of the Department of Environmental Conservation’s (DEC) deer management program. The goal of this analysis was to ascertain media depiction of DEC’s deer management program during the 1985-97 time period. Specifically, this research examines how deer management issues were portrayed both prior to and after implementation of a DEC public participation program (the Citizen Task Force [CTF] process) to determine if deer management issues received more favorable coverage after CTFs were implemented.
