Relative Habitat- And Browse-Use Of Native Desert Mule Deer And Exotic Oryx In The Greater San Andres Mountains, New Mexico, 2010 New Mexico State University
Relative Habitat- And Browse-Use Of Native Desert Mule Deer And Exotic Oryx In The Greater San Andres Mountains, New Mexico, Brock D. Hoenes, Louis C. Bender
Introduced oryx (Oryx gazella gazella) have expanded into the San Andres Mountains of south-central New Mexico, but little is known of concurrent habitat used by oryx and desert mule deer (Odocoileus hemionus crooki); the latter in New Mexico is a species of special concern that has declined significantly since the introduction of oryx. We used fecal-pellet and browse surveys in combination with presence modeling to identify differences in relative use of habitat types, distribution, and browsing of highly palatable, highly preferred (hereafter, key) plant species during 2004 to 2006 to assess the potential for direct competition in use of resources ...
European Starling Preferences For Bait Substrates Used In Drc-1339 Applications, 2010 USDA/APHIS/Wildlife Services’ National Wildlife Research Center
European Starling Preferences For Bait Substrates Used In Drc-1339 Applications, H. Jeffrey Homan, George M. Linz, Scott Beckerman, Anthony G. Duffiney, Thomas D. Halstead
Additional bait substrates for the avicide, DRC-1339 Concentrate (3-chloro-4- methylaniline hydrochloride), could provide USDA/Wildlife Services with more fl exibility when managing nuisance populations of European starlings (Sturnus vulgaris) at livestock facilities. From January 11 to 21, 2008, we conducted 11 2-choice preference tests with 6 bait types at a feedlot in central Kansas. The baits included cracked corn mixed with lard (2 concentrations), 2 forms of distiller’s grain (wet powder and pellets), 2 types of livestock feed (calf-starter pellet and sweet-feed mix), and a custom-produced poultry pellet (carrier pellet) made by USDA specifically for baiting starlings. We evaluated ...
Driver Knowledge, Beliefs, And Attitudes About Deer–Vehicle Collisions In Southern Michigan, 2010 Michigan State University
Driver Knowledge, Beliefs, And Attitudes About Deer–Vehicle Collisions In Southern Michigan, Alix Marcoux, Shawn J. Riley
Deer–vehicle collisions (DVCs) are one of the most frequent and costly human– wildlife conflict throughout the range of white-tailed deer (Odocoileus virginianus). We conducted a self-administered, mail-back survey of Michigan drivers to determine: (1) driver attitudes and knowledge about DVCs; (2) reporting rates of DVCs; and (3) effects of being in a DVC on attitudes toward desired deer population levels. From a sample of 3,600 randomly selected licensed drivers >18 years of age in southeast Michigan, we obtained 1,653 completed questionnaires (48% response rate). Although 18% of respondents reported experiencing >1 DVC within 5 years of the ...
Effectiveness Of Deer Repellents In Connecticut, 2010 Connecticut Agricultural Experiment Station
Effectiveness Of Deer Repellents In Connecticut, Jeffrey S. Ward, Scott C. Williams
Browsing by overabundant herds of white-tailed deer (Odocoileus virginianus) can cause significant economic damage to agricultural crops and landscape plantings. In many instances, for both commercial growers and homeowners, commercially available repellents may be an appealing alternative to physical exclusion and lethal control of animals. We tested 10 different commercially-available repellents (Chew-Not®, Deer Off®, Deer-Away® Big Game Repellent, Plantskydd®, Bobbex®, Liquid Fence®, Deer Solution®, Hinder®, Repellex® systemic tablets, and coyote urine) on yews (Taxus cuspidata Densiformis) at 2 different locations in Connecticut. The study included both positive (fence) and negative (no treatment) controls. We planted yews in 2 blocks at ...
Effects Of Aquaculture On Migration And Movement Patterns Of Double-Crested Cormorants, 2010 USDA/APHIS/Wildlife Services' National Wildlife Research Center
Effects Of Aquaculture On Migration And Movement Patterns Of Double-Crested Cormorants, D. Tommy King, Bradley F. Blackwell, Brian S. Dorr, Jerrold L. Belant
We analyzed 10,620 recovery records for double-crested cormorants (Phalacrocorax auritus) banded as nestlings from 1923 to 2006 to determine the population’s age structure, migration routes, dispersal patterns, and the possible influence of the expansion of the aquaculture industry in the southeastern United States on these population characteristics. Ninety-nine percent of the birds were banded during June to August, and 78% were banded as pre-fledged birds. Cormorants banded in the interior region of the United States comprised 91% of all birds banded from 1955 to 2006; these birds wintered primarily in the Lower Mississippi Valley and the northern Gulf ...
Testing Fladry As A Nonlethal Management Tool For Wolves And Coyotes In Michigan, 2010 Central Michigan University
Testing Fladry As A Nonlethal Management Tool For Wolves And Coyotes In Michigan, Sarah J. Davidson-Nelson, Thomas M. Gehring
Several forms of nonlethal management exist, but fi eld testing is problematic, and few such techniques have been tested on free-ranging wolves (Canis lupus) or other predators. We tested fladry in the eastern Upper Peninsula of Michigan during the summers of 2004 and 2005 on treatment farms and control farms. Wolf visitation inside pastures, compared to those outside pastures, was less on fladry-protected farms (U = 45, n = 7, P = 0.004); whereas, we found no difference in wolf visitation inside and outside of pastures on control farms (U = 30, n = 7, P = 0.24). We found no difference in coyote ...
Evaluation Of Damage By Vertebrate Pests In California Vineyards And Control Of Wild Turkeys By Bioacoustics, 2010 University of California, Davis
Evaluation Of Damage By Vertebrate Pests In California Vineyards And Control Of Wild Turkeys By Bioacoustics, Robert W. Coates, Michael J. Delwiche, W. Paul Gorenzel, Terrell P. Salmon
Complaints of agricultural damage by wild turkeys (Meleagris gallopavo), particularly from wine grape growers, have increased in California. We assessed damage by vertebrate pests in vineyards and tested a bioacoustic-aversion technique for turkeys as an alternative to other control techniques (e.g., reflective tape, trapping, bird netting). We selected 12 vineyards in the Napa Valley and Sierra Foothills American Viticultural Areas of California. We conducted damage surveys to assess percentages of missing or damaged grapes (i.e., grapes that had been stripped, pecked, and plucked) for every grape cluster on 20 randomly-selected vines before harvest in 2007 and on 40 ...

Metapopulation Dynamics Of Mid-Continent Lesser Snow Geese: Implications For Management, 2010 Utah State University
Metapopulation Dynamics Of Mid-Continent Lesser Snow Geese: Implications For Management, Lise M. Aubry, Robert F. Rockwell, David N. Koons
The rapid increase in abundance of lesser snow goose (LSG; Chen caerulescens caerulescens) numbers and their devastating effects on arctic and subarctic habitats has inspired much research on the use of population models for defining appropriate management policies. We use the not yet considered metapopulation approach to examine the elasticity of mid-continent LSG population dynamics to changes in underlying vital rates to determine whether management efforts aimed at decreasing burgeoning numbers should be reevaluated. After considering a variety of geographic scenarios in the metapopulation model, we found that changes in survival would still have a larger impact on population dynamics ...
Selection Of Pathways To Foraging Sites In Crop Fields By Flightless Canada Geese, 2010 South Dakota State University
Selection Of Pathways To Foraging Sites In Crop Fields By Flightless Canada Geese, Troy M. Radtke, Charles D. Dieter
Geese, especially when they are flightless, can cause significant crop damage. We determined the effects of shoreline characteristics on foraging site selection by flightless Canada geese (Branta canadensis) in South Dakota. Distance from edge of crop field to wetland and visual obstruction by vegetation were important determinants of pathway selection by geese. Geese used crop fields for foraging that were closer to water than unused fields. Geese accessed those fields along pathways with less visual obstruction by vegetation than unused pathways. Our data suggest that this distance of crops to wetlands is the most important shoreline characteristic determining where flightless ...
Nest-Site Selection And Nesting Ecology Of Giant Canada Geese In Central Tennessee, 2010 Tennessee Technological University
Nest-Site Selection And Nesting Ecology Of Giant Canada Geese In Central Tennessee, Jason S. Carbaugh, Daniel L. Combs, Eric M. Dunton
Little information is available on giant Canada goose (Branta canadensis maxima) nest-site selection on isolated nesting ponds. We monitored 46 island and 72 shoreline nests in the Upper Cumberland (UC) region of central Tennessee during 2002 and 2003. We measured 6 habitat variables at nesting ponds and randomly-selected non-nesting ponds. We used logistic regression to determine which habitat variables were important in nest-site selection. Presence of an island was the most important variable, but it was excluded from the final analysis because of quasi-separation (i.e., geese nested on all known islands in the study area). Geese that nested on ...
Fate Of Captive-Reared And Released Mallards On Eastern Long Island, New York, 2010 State University of New York
Fate Of Captive-Reared And Released Mallards On Eastern Long Island, New York, Carrie E. Osborne, Bryan L. Swift, Guy A. Baldassarre
We studied captive-reared mallards (Anas platyrhynchos; CRMs) released on eastern Long Island, New York, in 2006 to 2007 and 2007 to 2008 to determine: (1) survival rates of CRMs; (2) contribution to hunter harvest; (3) local movements; and (4) pair status, reproductive behavior, and production of CRMs. We banded and released 100 CRMs in November 2006 of which 20 were radio-marked. In November 2007, we banded and released 299 CRMs of which 60 were radio-marked. We used Program MARK to determine weekly survival estimates (0.53 to 1.00) up to 24 weeks after release; cumulative survival from November to ...
Estimating Annual Vertebrate Mortality On Roads At Saguaro National Park, Arizona, 2010 University of Wyoming
Estimating Annual Vertebrate Mortality On Roads At Saguaro National Park, Arizona, Kenneth Gerow, Natasha C. Kline, Don E. Swann, Marin Pokorny
Road-killed vertebrates are a conspicuous effect of roads on animals, particularly in natural preserves where wildlife is protected. Knowledge of the number of vertebrates killed by vehicles in a national park or other natural area is important for managers, but these numbers are difficult to estimate because such mortality patterns vary greatly in space and time and by taxonomic group. Additionally, animals killed by vehicles may be difficult to observe, particularly during driving surveys, and carcasses may not persist between surveys due to scavenging and other factors. We modified an estimator previously developed for determining bird mortality at wind turbines ...
Refinement Of Biomarker Pentosidine Methodology For Use On Aging Birds, 2010 West Virginia University
Refinement Of Biomarker Pentosidine Methodology For Use On Aging Birds, Crissa K. Cooey, Jesse A. Fallon, Michael L. Avery, James T. Anderson, Elizabeth A. Falkenstein, Hillar Klandorf
There is no reliable method for determining age for most species of long-lived birds. Recent success using the skin chemical pentosidine as a biomarker has shown promise as an aging tool for birds. Pentosidine levels have been determined only from the breast tissue of carcasses, and we sought to refine the procedure with respect to biopsy size and location for safe and effective use on living birds. We compared pentosidine concentrations in 4 skin-size samples (4, 6, 8, and 20-mm diameter biopsies) from the breast of black vulture (Coragyps atratus) carcasses. We also compared pentosidine levels from breast and patagial ...
Bulldozers And Blueberries: Managing Fence Damage By Bare-Nosed Wombats At The Agricultural–Riparian Interface, Philip Borchard, Ian A. Wright
Fence damage by bare-nosed wombats (Vombatus ursinus) can be a serious problem for farmers wishing to reduce herbivory by other herbivores on valuable crops. We investigated the effectiveness of exclusion fencing to prevent the incursion of unwanted native and feral herbivores and the use of swinging gates designed to allow wombats to pass through the fence without having to damage it. We also examined the temporal response of animals toward exclusion fencing and wombat gates. The 10-month study took place on the interface between natural riparian vegetation and a 22-ha blueberry (Vaccinium corymbosum) orchard in southeastern Australia. Following the testing ...
Late Summer Movements By Giant Canada Geese In Relation To A September Hunting Season, 2010 South Dakota State University
Late Summer Movements By Giant Canada Geese In Relation To A September Hunting Season, Charles D. Dieter, Bobby J. Anderson, Jeffrey S. Gleason, Paul W. Mammenga, Spencer Vaa
The population of giant Canada geese (Branta canadensis maxima) breeding in eastern South Dakota has increased dramatically since reintroduction efforts began in the 1960s. May breeding population levels of giant Canada geese exceeded population management goals set by the South Dakota Department of Game, Fish and Parks (SDGFP) by the mid-1990s, and the population has continued to increase into the 2000s. This population increase was accompanied by an increase in goose-related conflicts such as crop depredation. In 1996, a September hunting season was implemented in select counties in eastern South Dakota in an effort to reduce the giant Canada goose ...
An Effective Chemical Deterrent For Invasive Cuban Treefrogs, 2010 University of Florida
An Effective Chemical Deterrent For Invasive Cuban Treefrogs, Steve A. Johnson, Monica E. Mcgarrity, Christina L. Staudhammer
Introduced vertebrates have a variety of impacts on ecosystems and economies, and many cause problems for humans. One such problem is the loss of electrical power when invasive animals cause short circuits in power-transmission equipment. Cuban treefrogs (Osteopilus septentrionalis) are known to cause power outages and are a nuisance to humans when they invade homes and defecate on doors and windows. These large, slightly toxic treefrogs were introduced into Florida from the Caribbean. They now occur throughout the peninsula of Florida and are spreading to other states in the Southeast. We used refuge choice experiments to test the effectiveness of ...
