Carrion Seeking In Brown Tree Snakes: Importance Of Olfactory And Visual Cues, John A. Shivik, Larry Clark Apr 1997

Carrion Seeking In Brown Tree Snakes: Importance Of Olfactory And Visual Cues, John A. Shivik, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

We performed field experiments to examine brown tree snake (Boiga irregularis) attraction to carrion. These snakes were attracted to carrion and entered traps baited with dead mice as readily as traps baited with live mice. Using the cues arising from both live and dead prey, we examined the relative importance of visual and chemical cues to brown tree snakes. With carrion lures, chemical cues alone were sufficient for attracting and capturing snakes, but with live prey lures visual cues were required to attract and capture brown tree snakes. Our study presents the first experimental field evidence showing carrion …

Impacts Of Air Temperature Variations On The Boro Rice Phenology In Bangladesh: Implications For Irrigation Requirements, Rezaul Mahmood Apr 1997

Impacts Of Air Temperature Variations On The Boro Rice Phenology In Bangladesh: Implications For Irrigation Requirements, Rezaul Mahmood

School of Natural Resources: Faculty Publications

Air temperature significantly affects crop phenology. Numerous experiments have shown that prevailing air temperature determines the length of crop growth stages. Irrigation field requirements depend on the length of the crop growth stages. In the present study, a physically based parametric model, YIELD, has been applied to estimate the impacts of fluctuating air temperature (due to inter-annual climatic variability and global warming) on evapotranspiration water requirements and the length of growth stages of the irrigated boro rice in Bangladesh. The YIELD model is crop specific and crop-growth-stage specific which is a compromise between area-specific regression models and complex crop growth …


Microzooplankton Dynamics In Lower Chesapeake Bay And Its Major Tributaries, Gyung Soo Park Apr 1997

Microzooplankton Dynamics In Lower Chesapeake Bay And Its Major Tributaries, Gyung Soo Park

Biological Sciences Theses & Dissertations

This study identified the temporal and spatial variability of microzooplankton density and biomass at 14 stations located within Chesapeake Bay and four rivers. Microzooplankton are defined as those heterotrophic organisms which range from 20 to 200 $\mu$m in size, and in this study were mainly composed of copepod nauplii, rotifers, and ciliates. Ciliates were the most abundant microzooplankton, comprising more than 90% of the total density, with copepod nauplii representing approximately 50% of the total microzooplankton biomass (carbon content). Rotifers contributed less than 5% for both density and biomass of the total microzooplankton.

Maximum ciliate abundance occurred from spring to …

Assessing The Hazard To Granivorous Birds Feeding On Chemically Treated Seeds, Michael L. Avery, David L. Fischer, Thomas M. Primus Mar 1997

Assessing The Hazard To Granivorous Birds Feeding On Chemically Treated Seeds, Michael L. Avery, David L. Fischer, Thomas M. Primus

United States Department of Agriculture Wildlife Services: Staff Publications

Current methods for evaluating hazards to seed-eating birds are based on estimated exposure per unit area and assume that birds ingest all of the chemical on a treated seed. In an earlier study, however, it was determined that red-winged blackbirds removed only about 15% of an insecticidal treatment applied to individual rice seeds. Here, we extend those findings by examining the seed-handling behavior of four granivorous bird species exposed to millet, rice, sunflower and sorghum treated with imidacloprid. Mourning doves (Zenaida macroura L.) swallowed the seed whole. House finches (Carpodacus mexicanus Muller), red-winged blackbirds (Agelaius phoeniceus L.) …

Bulletin 4333 - Furrow Sowing On Water Repellent Soils, Paul Blackwell, Grant Morrow Mar 1997

Bulletin 4333 - Furrow Sowing On Water Repellent Soils, Paul Blackwell, Grant Morrow

Bulletins 4000 -

This Bulletin discusses the benefits that furrow sowing brings to crop growth and production on water repellent sand, based on research and farm observations in Western Australian. By understanding the benefits and risks of several key processes, producers can better evaluate the potential role of furrow sowing in combating water repellency. This is true whether one is using direct drilling, no-till (narrow points or discs) or zero till (single, double or triple disc openers) methods.


Composting Landscape Waste From The University Of Nevada, Las Vegas, K. Jill Hammond Mar 1997

Composting Landscape Waste From The University Of Nevada, Las Vegas, K. Jill Hammond

UNLV Theses, Dissertations, Professional Papers, and Capstones

The University of Nevada, Las Vegas is a major producer of organic waste in the Las Vegas Valley. Composting landscape wastes is one way to reduce both landfill dumping and fertilizer costs for the university. It is also an environmentally friendly means of curbing a nationwide problem: unnecessary use of landfill space. Three sites within Clark County were analyzed for the feasibility of composting: Frenchman Mountain, UNLV Campus, and Boulder City Landfill. Using cost analysis, water availability, and other factors to analyze each site, Boulder City Landfill appears to be the best place to house UNLV's composting operation. Composting in …

Evaluating Cable Resistance To Pocket Gopher Damage - A Review, Craig A. Ramey, Geraldine R. Mccann Feb 1997

Evaluating Cable Resistance To Pocket Gopher Damage - A Review, Craig A. Ramey, Geraldine R. Mccann

Great Plains Wildlife Damage Control Workshop Proceedings

The National Wildlife Research Center, formerly known as the Denver Wildlife Research Center (DWRC), collaborated with telecommunications and energy industries to evaluate cable resistance to pocket gopher damage for 29 years (1966 to 1995). Recently, DWRC's evaluation process was transferred to private contract laboratories. This review summarizes the chronology of key investigations and procedures that were used and first published on cable resistance to rodent damage. The longstanding cooperative goal of both DWRC scientists and industry engineers was the development of rodent-proof, buried cables and ducts. Even though most data collected were proprietary, extensive laboratory testing at DWRC provided data …


Control Of Nuisance Birds By Fogging With Rejex-It® Tp-40, Peter F. Vogt Feb 1997

Control Of Nuisance Birds By Fogging With Rejex-It® Tp-40, Peter F. Vogt

Great Plains Wildlife Damage Control Workshop Proceedings

Many bird problems are caused by birds congregating, roosting, loafing, and nesting rather than by the birds’ feeding activities. No matter what their activity, eventually birds will need to be driven off, preferably in a so-called “friendly” way without harming the birds or other animals. Unlike other avian aversion methods, fogging of ReJeX-iT® TP-40 relies on the exposure of the target birds to the aerosol rather than relying on birds eating treated food. Best results are achieved when birds congregate in the early morning or early evening when they settle down. After several exposures the birds generally leave the area …


Impact Of Preventive Aerial Coyote Hunting On Sheep Losses To Coyote Predation, Kimberly K. Wagner, Michael R. Conover Feb 1997

Impact Of Preventive Aerial Coyote Hunting On Sheep Losses To Coyote Predation, Kimberly K. Wagner, Michael R. Conover

Great Plains Wildlife Damage Control Workshop Proceedings

Coyote (Canis latrans) predation is a serious problem for livestock producers in the Western U.S. In Utah, Idaho, and Wyoming, 34% of all producer-reported sheep and lamb losses were to coyote predation, amounting to $4.8 million in losses during 1995. Although preventive aerial hunting is commonly used by agriculture agencies in the Intermountain West to reduce coyote (Canis latrans) predation on sheep (Ovis aries), only limited data are available on the efficacy of the technique. We assessed the impact of winter (January - March) aerial coyote hunting on sheep losses to coyotes and the …


Development And Registration Of A Pracical Tranquilizer Trap Device (Ttd) For Foot-Hold Traps, Doris E. Zemlicka, D. Pete Sahr, Peter J. Savarie, Frederick F. Knowlton, F. Sherman Blom, Jerrold L. Belant Feb 1997

Development And Registration Of A Pracical Tranquilizer Trap Device (Ttd) For Foot-Hold Traps, Doris E. Zemlicka, D. Pete Sahr, Peter J. Savarie, Frederick F. Knowlton, F. Sherman Blom, Jerrold L. Belant

Great Plains Wildlife Damage Control Workshop Proceedings

Foot-hold traps can be used to selectively capture coyotes (Canis latrans) and wolves (C. lupus). However, injuries to captured animals sometimes occur when they struggle to escape. Tranquilizer trap devices (TTDs) reduce struggling and injuries but prototype TTDs were too expensive for widespread use by animal damage control (ADC) operational personnel. For this reason, the Pocatello Supply Depot (PSD) and the National Wildlife Research Center (NWRC) are investigating alternative TTD designs. A molded-rubber TTD will be available from the PSD for coyotes, and the NWRC continues to explore other cheaper TTD designs. A practical TTD …


Field Trials Of Alpha-Chloralose And Drc-1339 For Reducing Numbers Of Herring Gulls, Paul P. Woronecki, Richard A. Dolbeer, Thomas W. Seamans Feb 1997

Field Trials Of Alpha-Chloralose And Drc-1339 For Reducing Numbers Of Herring Gulls, Paul P. Woronecki, Richard A. Dolbeer, Thomas W. Seamans

Great Plains Wildlife Damage Control Workshop Proceedings

We compared the potential of Alpha-chloralose (A-C) and DRC-1339 to reduce a nesting population of herring gulls at an industrial site in Ohio in 1988. Almost all treated baits were consumed by gulls but only about one affected gull was noted for every 10 baits consumed of either chemical. A test indicated our DRC-1339 baits. containing 3.7 - 7.4 times the published LD value, were not lethal to most captive herring gulls living in fresh water. LD values of A-C and DRC-1339 need to be more precisely estimated for gull species in fresh and salt water environments.


Cooperative Wolf Depredation Management In Wisconsin, Robert C. Willging, Adrian P. Wydeven Feb 1997

Cooperative Wolf Depredation Management In Wisconsin, Robert C. Willging, Adrian P. Wydeven

Great Plains Wildlife Damage Control Workshop Proceedings

A depredation management plan was an important component of Federal and State recovery plans for the endangered gray wolf (Canis lupus) in Wisconsin. The Wisconsin Department of Natural Resources (WDNR) entered into a cooperative agreement with USDA-APHIS-ADC to cooperatively manage wolf depredations. Response to complaints involving wolf-dog hybrids was also part of the cooperative agreement. From 1990-1996 ADC investigated 60 wolf complaints and confirmed 10 depredations. In the same time period, WDNR paid a total of $21,376 in compensation payments for 21 incidents of wolf depredations. Wolves may be downlisted from endangered to threatened within the next five …


Wildlife-Caused Losses Of Agricultural Commodities In 1994 With Emphasis On The Great Plains, A.P. Wywialowski Feb 1997

Wildlife-Caused Losses Of Agricultural Commodities In 1994 With Emphasis On The Great Plains, A.P. Wywialowski

Great Plains Wildlife Damage Control Workshop Proceedings


The USDA, National Agricultural Statistics Service (NASS) surveyed 16,000 agricultural producers in January 1995. Of 10,144 respondents nationwide, 58% reported wildlife-caused losses of their commodities, an increase from 55% in 1989. Based on the median value of all producers' estimates of their losses, wildlife-caused losses cost producers approximately $591 million in 1994, $130 million more than in 1989. Losses presented are based on median producer estimates which have been shown to be consistent with field-measured estimates of damage. Because the dollar value of losses are based on median estimates, extremes of reported losses do not affect these results. If all …


Relative Effectiveness Of Various Breeds Of Livestock Guarding Dogs For Reducing Predation On Domestic Sheep In Colorado, William F. Andelt, Stuart N. Hopper Feb 1997

Relative Effectiveness Of Various Breeds Of Livestock Guarding Dogs For Reducing Predation On Domestic Sheep In Colorado, William F. Andelt, Stuart N. Hopper

Great Plains Wildlife Damage Control Workshop Proceedings

We surveyed 59 livestock producers that used multiple breeds of livestock guarding dogs to determine their ratings of the relative effectiveness of guarding dogs for deterring predation on domestic sheep in Colorado during 1995. Significantly (P < 0.05) more producers rated Akbash dogs as more effective than Great Pyrenees for deterring predation by coyotes (Canis latrans), black bears (Ursus americanus), mountain lions (Felis concolor), domestic dogs, and all predators combined. Significantly more producers also rated Akbash dogs as more effective than Komondors for deterring predation by coyotes and all predators combined. Great Pyrenees and Komondors were rated as similar in effectiveness for deterring predation. Significantly more producers rated Akbash dogs as more aggressive, …
