A Comparison Of Phytoplankton Communities In Lake Prince And The Western Branch Reservoir, Suffolk, Virginia, Cara Marie Muscio
A Comparison Of Phytoplankton Communities In Lake Prince And The Western Branch Reservoir, Suffolk, Virginia, Cara Marie Muscio
Biological Sciences Theses & Dissertations
Lake Prince and the Western Branch Reservoir are two eutrophic bodies of water located in Suffolk, Virginia. Lake Prince and its two small tributaries join the Western branch via a constructed spillway. This lake system is a source of water for the surrounding municipalities, and a recreational area for community citizens. In the past, these bodies of water had repeated incidents of low oxygen and nuisance algal blooms, particularly cyanobacteria species. As a result aerators have been installed in the main body of both Lake Prince and the Western Branch Reservoir. In addition, a pipeline has been installed from North …

Egg Oil: An Avian Population Control Tool
Egg Oil: An Avian Population Control Tool
United States Department of Agriculture Wildlife Services: Staff Publications
The Animal and Plant Health Inspection Service's Wildlife Services (WS) program uses many methods to manage populations of gulls, waterfowl, and other birds in areas where they create problems. Methods include trapping and relocation, surgical sterilization, mechanical scare devices, repellents, and hunting. However, these methods, and others that reduce or prevent eggs from hatching-such as shaking, freezing, addling, nest destruction, and egg removal-are labor intensive and may not be effective in operational programs.
The application of various oils (of mineral and vegetable origin) to eggs during the nesting season to prevent hatching is less labor intensive. In addition, this method …

Disease Emergence In Birds: Challenges For The Twenty-First Century, Milton Friend, Robert G. Mclean, F. Joshua Dein
Disease Emergence In Birds: Challenges For The Twenty-First Century, Milton Friend, Robert G. Mclean, F. Joshua Dein
United States Department of Agriculture Wildlife Services: Staff Publications
Finch (Carpodacus mexicanus) conjunctivitis is an example of the rapid geographic spread that can result from disease emergence in naive populations. That event was neither novel nor transient relative to its occurrence or effects. Disease emergence and reemergence are hallmarks of the latter part of the twentieth century (Center for Disease Control 1994, Levins et al. 1994, DaSilva and Laccarino 1999, Gratz 1999). Current examples involving domestic animals include the problems in Europe with bovine spongiform encephalopathy (BSE, or ‘‘mad cow disease’’) (Brown 2001) and foot-and-mouth disease (FMD) (Kitching 1999). Human health has been affected by diseases caused …
Using Iophenoxic Acid Injections Of Prey To Identify Mammals That Feed On Them, Frederick F. Knowlton, Stanley R. Olmstead
Using Iophenoxic Acid Injections Of Prey To Identify Mammals That Feed On Them, Frederick F. Knowlton, Stanley R. Olmstead
United States Department of Agriculture Wildlife Services: Staff Publications
Identifying species or individuals that feed upon other species of animals is an important aspect of some predation studies. We evaluated the effectiveness with which the biomark associated with iophenoxic acid (IA) injections was transferred from domestic goats to coyotes (Canis latrans) that fed on them. We injected doses of 100, 300, or 1,000 mg of IA into goats to raise serum iodine levels, fed meat from the injected goats to coyotes, and monitored serum iodine levels in both species for about I20 days. Within 3 days, mean serum iodine levels in goats increased from 5.33 mcg/I 00 ml to …
Dogs Increase Recovery Of Passerine Carcasses In Dense Vegetation, H. Jeffrey Homan, George M. Linz, Brian D. Peer
Dogs Increase Recovery Of Passerine Carcasses In Dense Vegetation, H. Jeffrey Homan, George M. Linz, Brian D. Peer
United States Department of Agriculture Wildlife Services: Staff Publications
Wildlife managers use carcass searches to assess mortality resulting from biological (e.g., diseases) and physical (e.g., structure collisions) sources. Carcass searches may occur over large areas and need to be completed rapidly because of scavenging and decomposition. However, small carcasses are often missed when dense vegetation is searched. We placed carcasses of house sparrows (Passer domesticus) in dense cover of residual and newly grown vegetation and compared searching efficiency of humans and canines. Dogs received no special training in searching for passerine carcasses. In 36 trials conducted in 5 x 40-m plots, human searchers found 45% (SD=19) of the carcasses …
Comparison Of Active Ingredients And Delivery Systems In Deer Repellents, Kimberly K. Wagner, Dale L. Nolte
Comparison Of Active Ingredients And Delivery Systems In Deer Repellents, Kimberly K. Wagner, Dale L. Nolte
United States Department of Agriculture Wildlife Services: Staff Publications
In some situations chemical repellents are a socially appealing nonlethal alternative to reduce deer (Odocoileus spp.) damage to plants. New products are continually becoming available, but their ability to repel deer is very variable. We tested 20 repellents representing 4 modes of action (fear, pain, taste, and aversive conditioning) and 2 delivery systems (topical applications and area repellents [scent packets]) to evaluate current products and identify trends that could be used to predict efficacy of future products. During fall 1998, we placed treated western red cedar (Thuja plicata) seedlings in pastures with black-tai led deer (Odocoileus …
Pulp Cavity-Tooth Width Ratios From Known-Age And Wild-Caught Coyotes Determined By Radiography, Frederick F. Knowlton, Susan L. Whittemore
Pulp Cavity-Tooth Width Ratios From Known-Age And Wild-Caught Coyotes Determined By Radiography, Frederick F. Knowlton, Susan L. Whittemore
United States Department of Agriculture Wildlife Services: Staff Publications
Although the relative sizes of pulp cavities in teeth are used frequently to identify various age classes of carnivores, validation of the technique has received little attention. We measured the pulp cavities and tooth widths based on radiographs of canine and premolar teeth from a large sample of known-age, pen-reared coyotes (Canis latrans) and from samples of wild-caught coyotes of unknown age. The ratio of pulp cavity to tooth width decreased rapidly through the first year of life. Although canine tooth ratios of juvenile, yearling, and adult coyotes differed, variations within yearling and adult groups precluded accurate assignment …
Burning And Burying In Connecticut: Are Regional Solutions To Solid Waste Disposal Equitable?, Timothy Black, John A. Stewart
Burning And Burying In Connecticut: Are Regional Solutions To Solid Waste Disposal Equitable?, Timothy Black, John A. Stewart
New England Journal of Public Policy
To comply with federal legislation, states throughout the country are replacing old town dumps with a regional system for municipal solid waste disposal.This system includes trash-to-energy incinerators and ash landfills as well as recycling and reduction facilities. While these new types of facilities are expected to be environmentally safer, they have concentrated the disposal process of waste generated throughout the state in fewer locations. State leaders champion the use of newer, cleaner disposal methods, while local community groups complain that they have become the dumping grounds for the state. This is the first environmental equity study to examine whether these …

Black Bear Forest Damage In Washington State, Usa: Economic, Ecological, Social Aspects, Georg J. Ziegltrum, Dale L. Nolte
United States Department of Agriculture Wildlife Services: Staff Publications
Black bear (Ursus americanus) damage to coniferous forests can be detrimental to the forest products industry in Washington state. Value of timber damage, west of the Cascade Mountains is millions of dollars every year. The Washington Forest Protection Association’s (WFPA) Animal Damage Control Program (ADCP) manages bear damage in cooperation with the Washington Department of Fish and Wildlife (WDFW). Bears can significantly affect the viability of other wildlife, for example, elk (Cervus elaphus) calf predation on calving sites. Conversely, bear-damaged trees add to the snags and dead wood on the ground, which provide important habitat and …
Monitoring Of Terrestrial Carnivore Populations, Eric M. Gese
Monitoring Of Terrestrial Carnivore Populations, Eric M. Gese
United States Department of Agriculture Wildlife Services: Staff Publications
There is increasing concern about the status and distribution of terrestrial carnivore populations throughout the world (Schaller, 1996). Changes in land-use practices, habitat loss and fragmentation, sanctioned human persecution, declines in natural prey, disease, illegal poaching, and increased competition within carnivore guilds have brought about a general decline in several carnivore populations with some species now occupying a fragment of their former range. The continued loss of suitable habitat due to an ever expanding human population has placed the issue of conservation and protection of some carnivores as a top environmental priority and/or controversy for many agencies and organizations. Paramount …

Porcine Zona Pellucida Immunocontraception: Long-Term Health Effects On White-Tailed Deer, Lowell A. Miller, Ken Crane, Stan Gaddis, Gary J. Killian
United States Department of Agriculture Wildlife Services: Staff Publications
As part of a 9-year study on the contraceptive effects of Porcine Zona Pellucida (PZP) on white-tailed deer (Odocoileus virginianus), we analyzed serum chemistry panels during the first 4 years. This included the first 2 years when does were being actively immunized, and 2 years post-immunization. The chemistry panel was designed to detect pathologies that might result from the immunization of the deer. Blood chemistry results did not suggest any pathological changes resulting from the immunization. Seasonal differences in serum cholesterol were similar in both the control and PZP-treated groups. Seasonal changes in the mean body weights of …

Effect Of Primary And Secondary Repellents On European Starlings: An Initial Assessment, Roger W. Sayre, Larry Clark
United States Department of Agriculture Wildlife Services: Staff Publications
Wildlife managers need chemical repellents that are effective at deterring damage by birds, but these repellents must be environmentally and toxicologically safe. The number of commercially available bird repellents has been reduced because of concerns about environmental safety. Currently, there are 2 categories of avian repellents. Chemicals that are reflexively avoided by birds because they irritate the peripheral chemical senses are referred to as primary repellents. Chemicals that cause gastrointestinal illness and learned avoidance of ancillary sensory cues that are paired with the illness are known as secondary repellents. Secondary repellents most often identified as the most effective avian repellents …

Use Of Acetaminophen For Large-Scale Control Of Brown Treesnakes, Peter J. Savarie, John A. Shivik, Gary C. White, Jerome C. Hurley, Larry Clark
United States Department of Agriculture Wildlife Services: Staff Publications
Because the brown treesnake (Boiga irregularis) has virtually extirpated the avifauna on Guam and is a threat to other Pacific islands, the development of alternative and efficient control methods is required. Therefore, we performed a large-scale field experiment to determine whether the acetaminophen baits we developed could be used to reduce population levels of brown treesnakes on Guam. Toxic baits were made by inserting 80 mg of acetaminophen into dead neonatal mice, and these mouse baits were used to treat plots. Reference plots were baited with unadulterated baits. We used mark-recapture methods to estimate snake abundance on plots …

United States Department of Agriculture Wildlife Services: Staff Publications
Ring-billed Gull Larus delawarensis and California Gull L. californicus populations have increased throughout the western United States in close association with human settlement (Conover 1983; Ryder 1993). On Upper Nelson Island in the Columbia River, the number of Ring-billed and California Gull nests increased from 4 600 in 1978 to 21 000 in 1999 (Thompson and Tabor 1981; Pochop, this manuscript). Agriculture and landfills provided food sources, and construction of reservoirs increased island nest sites for gulls (Ryder 1993). Gulls gather below hydroelectric facilities in the spring to feed on migrating juvenile salmonids (Steuber et al. 1995). Also, increased gull …
Great Egret Preference For Catfish Size Classes, Scott J. Werner, Mark E. Tobin, Paul B. Fioranelli
Great Egret Preference For Catfish Size Classes, Scott J. Werner, Mark E. Tobin, Paul B. Fioranelli
United States Department of Agriculture Wildlife Services: Staff Publications
Several species of fish-eating birds are commonly observed near aquaculture facilities in the southern United States. An understanding of the relationships between these birds and specific commodities is needed to interpret and manage bird impacts to aquacultural production. We conducted two foraging experiments to evaluate the preference o f Great Egrets (Ardea alba) for three specific size classes of Channel Catfish (Zctalurus punctatus). During six no-choice feeding trials, egrets consumed significantly more small (7.5-10 cm) fingerlings than medium (13- 18 cm) or large (23-23 cm) catfish. Egrets captured 19 large catfish, and ingested only two, even …

Objectives And Integrated Approaches For The Control Of Brown Tree Snakes, Richard M. Engeman, Daniel S. Vice
United States Department of Agriculture Wildlife Services: Staff Publications
The inadvertent introduction of the brown tree snake (Boiga irregularis) to Guam has resulted in the extirpation of most of the island’s native terrestrial vertebrates, has presented a health hazard to small children, and also has produced an economic problem. Management of brown tree snakes is aimed at a number of objectives, the foremost of which has been to deter its dispersal through Guam’s cargo traffic to other locations. Another objective is to reclaim areas on Guam for reintroduction of native wildlife. A related objective is the protection of small sensitive sites on Guam from brown tree snake …

Repelling Sandhill Cranes From Corn: Whole-Kernel Experiments With Captive Birds, Bradley F. Blackwell, David A. Helon, Richard A. Dolbeer
United States Department of Agriculture Wildlife Services: Staff Publications
Sandhill cranes (Grus canadensis) are opportunistic omnivores that incorporate both waste and unharvested cereal grains (Gramineae) in their diets. Limited hunting of cranes to reduce crop damage has had questionable results, and lethal control of depredating species is increasingly contentious. Our objectives were to evaluate anthraquinone-based Flight ControlTM and methyl anthranilate-based ReJeX-iTTM AG-36 as nontoxic avian foraging repellents in separate 2-choice pen tests with captive greater sandhill cranes (G. c. tabida) fed with whole-kernel corn (Zea mays). In both tests, crane pairs consumed, respectively, 8.6 and 9.8 times more untreated than treated …

A Direct Comparison Of Trapping And Spotlight Searches For Capturing Brown Tree Snakes On Guam, Richard M. Engeman, D.S. Vice
United States Department of Agriculture Wildlife Services: Staff Publications
Brown Tree Snake populations on Guam are controlled in the vicinities of cargo staging and transport areas to prevent their dispersal from Guam, and their populations are controlled in areas where endangered species are to be reintroduced. Trapping and night-time spotlight searches of fences are the two primary Brown Tree Snake population reduction methods used on Guam. We conducted a three month study comparing Brown Tree Snake captures by spotlighting fences to captures by trapping. Traps were placed either on the edge of the forest paralleling the fences, or they were hung on the fences. Applications of each capture method …

Daily Activity Budgets And Population Size Of American White Pelicans Wintering In South Louisiana And The Delta Region Of Mississippi, D. Tommy King, Scott J. Werner
United States Department of Agriculture Wildlife Services: Staff Publications
Twenty-one American White Pelicans (Pelecanus erythrorhynchos) were captured and fitted with radio-transmitters in South Louisiana and the delta region o f Mississippi during the winter and early spring of 1994-1997. The pelicans were monitored to determine their daily activity budgets while using different habitats such as catfish ponds, crawfish ponds, rivers, lakes, and bayous. Pelicans foraging at catfish ponds spent about 4% of their day foraging and 96% loafing, while pelicans foraging in other habitats spent about 28% of their day foraging and 72% loafing. For an individual bird, the mean number of foraging sessions per day was …

Bear Behavior In The Vicinity Of Supplemental Feeding Stations In Western Washington, Dale L. Nolte, Timothy J. Veenendaal, Georg J. Ziegltrum, Philipp Fersterer
United States Department of Agriculture Wildlife Services: Staff Publications
Black bear can inflict severe negative Impacts on timber stands in the northwestern United States. A supplemental feeding program to provide bears an alternative food source during spring is practiced in the state of Washington, and to a lesser extent in other states. We initiated concurrent studies to assess characteristics of bear that forage at feeding stations, the interactions of bears around feeders, and impacts of the program on bear territories. Numerous bears fed at stations, including females with and without cubs, yearlings, and males. Bear feeding bouts at stations were generally short, less than 15 minutes. Bears generally fed …

Effect Of Feeding Stations On The Home Ranges Of American Black Bears In Western Washington, Philipp Fersterer, Dale L. Nolte, Georg J. Ziegltrum, Hartmut Gossow
United States Department of Agriculture Wildlife Services: Staff Publications
Forest managers establish feeding stations throughout coniferous forests in western Washington that are vulnerable to American black bear (Ursus americanus) damage in the spring. This study was conducted to determine whether the home ranges of bears in areas with supplemental feeding were smaller than the home ranges of bears in similar adjacent areas without supplemental feeding. Home range sizes varied among bears. However, the home range sizes of bears in feeding areas did not differ (P > 0.35) from home ranges of bears in non-feeding areas. Male bears had larger (P = 0.0002) home ranges than female …
