Ichthyofaunal And Habitat Associations Of Distinct Populations Of Southern Redbelly Dace, Phoxinus Erythrogaster (Teliostei: Cyprinidae) In Mississippi, Martin O'Connell

Earth and Environmental Sciences Faculty Publications

Twenty-two field sites in W-central Mississippi were surveyed for southern red- belly dace Phoxinus erythrogaster to characterize habitat and ichthyofaunal associations of these 'endangered' disjunct populations. Phoxinus erythrogaster occurred at only six sites. Data assessed similarity among all sites and described microhabitat associations of P erythro- gaster. Five species, including Semotilus atromaculatus, Campostoma anomalum, Etheostoma whipplei, P erythrogaster and Pimephales notatus, comprised 95% of the total number of in- dividuals collected at P erythrogaster sites. Standardized abundance (number per seine haul) for S. atromaculatus was consistently high among all P erythrogaster sites, whereas standard- ized abundance for C. anomalum, P …

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 …

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 …

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

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 …

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

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 …

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, …

Food Habits Of Mountain Lions In The Trans-Pecos Region Of Texas, Rosemary A. Heinen, S. Kemble Canon

Great Plains Wildlife Damage Control Workshop Proceedings

Information regarding mountain lion (Felis concolor) food habits is relatively scarce overall, and this is particularly true in the Trans-Pecos region of Texas. Most information currently available is from Big Bend National Park where livestock are excluded and game animals are not actively managed. This study involved the analysis of 32 mountain lion stomachs collected throughout the Trans-Pecos over a 14 month period. Deer (Odocoileus spp.) and javelina (Tayassu tajacu) were the predominate prey species, each occurring in 39% of the stomachs analyzed. Domestic livestock was found in 9% of the total stomachs and non-game …

Depredation On Artificial Ground Nests By Japanese Macaques: The Unspoken Exotic In Texas, Justin G. Feild, Scott E. Henke, Justin G. Mccoy

Great Plains Wildlife Damage Control Workshop Proceedings

Japanese macaques (Macaca fuscata) are old world monkeys that were introduced to Texas in 1972, and their population has since increased to over 800 individuals. Macaques are considered to be primarily vegetarian but will opportunistically forage on a variety of food items. Therefore, the objective of this study was to determine if macaques impact the nest success of bobwhite quail (Colinus virginianus). In June 1996, 20 artificial ground nests simulating those of bobwhite quail were placed randomly in areas with and without macaques. Nests were checked at 3-day intervals for 24 days and nest success was …

Livestock Protection Collar Use In California, Robert M. Timm, Gary D. Simmons, John R. Hays

Great Plains Wildlife Damage Control Workshop Proceedings

Use of the Livestock Protection Collar (LP Collar) containing sodium fluoroacetate began on a research basis in October 1995 at the UC Hopland Research and Extension Center. Registration for use in California only by certified ADC specialists was granted in early 1996, and operational use in three north coast counties began in early 1997. Preparation for beginning operational use dealt with concerns regarding user certification, hazardous waste disposal, and public relations. We report on the success to date of using LP Collars to remove sheep-killing coyotes. Incidents in which non-target predators including mountain lions have attacked LP-Collared sheep are also …

Sheep Predation By Coyotes: A Behavioral Analysis, Ray T. Sterner

Great Plains Wildlife Damage Control Workshop Proceedings

This paper presents (1) a brief overview of several concepts important to predator-prey behaviors of coyotes, (2) results of an enclosure study of sheep-attack, -immobilization, and -ingestion responses involving 12 male coyotes (Canis latrans) that were paired with sheep after observing various sheep- predation events by conspecifics, and (3) an analysis of sheep predation based upon operant learning principles. Contrasts between comparative psychological and ethological approaches to the study of animal behavior are described. Results of the enclosure study (0.127-ha) showed that following matched-length trials of observing predation, non-predation, and lone sheep, 3, 2, and 1 coyote(s), respectively, …

To be an effective educator, you need to properly identify your audience and a proper medium in which to deliver your message.

Experimental Rodent Control At The Beef Cattle Research Center, Kansas State University, Philip S. Gipson, Charles D. Lee, Matthew L. Burenheide, Jan F. Kamler, Justin E. Kretzer, Daniel J. Martin, Celine C. Perchellet, Chad M. Willemssen, Jennifer Weins

Great Plains Wildlife Damage Control Workshop Proceedings

Little research has been conducted on rodent control techniques in livestock feedlot situations. We tested efficacy of several treatments including two anticoagulant baits, an acute toxicant and snap trapping to reduce rodent populations at the Beef Cattle Research Center at Kansas State University. Among the four treatments utilized, Contrac®, Blox®, and Ditrac® Tracking Powder reduced the number of active burrows. ZP® Rodent Bait had no observed effect on the rodent population and no rodents were taken with snap traps. Burrow activity appears to be a better census method when compared to corn consumption when rodents have access to unlimited food.

Dealing With The Policy Makers, Herb Manig

Great Plains Wildlife Damage Control Workshop Proceedings

First, “Why would policy makers be interested in wildlife damage control in the first place?” In response, I would have to say that the problems with wildlife are increasing in number, diversity and complexity. Policy makers cannot afford to ignore controversies caused by them. We have problems in transportation with deer/automobiles collisions. We have airplane engines ingesting birds. We have health problems with respect to disease. Wildlife damage costs money. We also have problems with aesthetics. Some of the homeowners may not lose a lot of money when deer nibble their shrubs but they certainly don't like the looks of …

Use Of Netted-Cage Traps In Population Management And Research Of Urban White-Tailed Deer, Kurt C. Vercauteren, Jeff Beringer, Scott Hygnstrom

Great Plains Wildlife Damage Control Workshop Proceedings

Growing populations of white-tailed deer (Odocoileus virginianus) in urban areas often conflict with local human interests and present challenges to natural resource managers. Netted-cage traps can be an important tool for management of urban deer populations where traditional control methods may not be appropriate or acceptable. We discuss the design of netted-cage traps, trapping techniques, and the handling of trapped deer.

Mylar Flags As Gull Deterrents, Jerrold L. Belant, Sheri K. Ickes

Great Plains Wildlife Damage Control Workshop Proceedings

During 1996, we evaluated the effectiveness of mylar flags for deterring herring gulls (Larus argentatus) from 2 nesting colonies (roof and breakwall) and herring and ring-billed (L. deglawarensis) gulls from 2 loafing sites at a landfill. Mylar flags (15 cm x 1.0 m) attached to wire or lathe supports were positioned at 6-m intervals at nesting colonies and 3- to 12-m intervals at loafing areas. For both nesting colonies, time of nest initiation, nest density, and clutch size in 1996 when flags were present was similar to or greater than values obtained for these parameters at …

The Coyote As An Ecological Model, Thomas A. Eddy, Cindy M. Moore

A topical outline was developed as a guide for implementing the study.

Technical Publication Of Wildlife Damage Research, Michael W. Fall, William B. Jackson

Great Plains Wildlife Damage Control Workshop Proceedings

The growth of the subdiscipline of wildlife damage research is producing a wealth of scientific information about methods of resolving conflicts between animals and people. Scientists working on these problems have, for many years, found difficulty in publishing the results of their applied research investigations in traditional scientific journal outlets, leading to a diverse information base that encompasses a variety of technical journals and a large “gray” literature in non-refereed publications. Although a number of current scientific journals welcome papers reporting the results of wildlife damage research, the identification of suitable primary outlets for such work, particularly for studies conducted …

Gifford Point/Fontenelle Forest Urban Deer Survival And Case Study, Jason D. Ekstein, Scott E. Hygnstrom

Great Plains Wildlife Damage Control Workshop Proceedings

From 1995-1996, we radio collared and/or ear tagged 98 white-tailed deer (Odocoileus virginianus) in an urban area of Bellevue, Nebraska. We determined the density to be 44 deer/km² and observed the movements of 52 collared does. The managed hunt and harvest results are discussed.

Size-Frequency Distribution Of Palaemonetes Pugio In Two New Jersey Estuaries And Predator-Prey Interactions With Fundulus Heterocolitus, Celine Santiago

Theses

Predation by Fundulus heteroclitus is known to be an important factor regulating the abundance and size distribution of Palaemonetes pugio in the salt marsh habitat.

A preliminary study showed that P. pugio from a polluted estuary, Piles Creek, were relatively larger than those found in a more pristine estuary, Little Sheepshead Creek. Possible causes could be differences in competition, inherent environmental components, reproductive effort, or predation. To investigate the differences in size frequency, data on relative abundances of both species and size frequency distribution of P. pugio were collected for comparison from the two estuaries.

It was determined that P. …

Oxidative Response Of Immobilized Bovine Blood To The Model Pollutant Phenol, Michael George Nickey

Theses

The primary purpose of this work is to determine if bovine blood can be studied in an immobilized cell bioreactor to determine if a phenol induced oxygen releasing optimum exists. This method of study has the potential to be used to determine what effects xenobiotics have on the oxidative activities of blood.

Three blood fractions containing approximately 21, 44, and 70% red blood cells (RBCs) were immobilized and placed in a recirculating bioreactor. These fractions were exposed injections of 0 ml, 3 ml, or 10 ml amounts of 2000 ppm phenol. The most active fraction was the 21% red cell …
