Changes In Coyote Activity Patterns Due To Reduced Exposure To Human Persecution, Ann M. Kitchen, Eric M. Gese, Edward R. Schauster

United States Department of Agriculture Wildlife Services: Staff Publications

Activity patterns in animals are influenced by a number of factors, including the animal's physiological adaptations, prey availability and distribution, and disturbances caused by predators and humans. We compared coyote (Canis latrans) activity patterns estimated using radio-tracking locations between 1983 and 1988 with those documented between 1996 and 1997 on the Pinon Canyon Maneuver Site, in southeastern Colorado. We tested the hypothesis that changes in the type of disturbance experienced by coyotes would result in changes in their activity patterns. Disturbance experienced by the coyote population studied during 1983-1988, included >50 years of intense exploitation (shooting and trapping by ranchers) …

Wildlife Strikes: A Growing And Costly Problem For Civil Aviation In The Usa, Sandra Wright, Richard Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Wildlife strikes, defined as aircraft collisions with birds or other animals, are a serious safety and economic concern in the USA and elsewhere. Liability issues related to wildlife strikes are also growing for airports and aircraft operators. In this paper, we will give examples of some significant strikes, show trends in wildlife strikes, explain why the strike problem is an increasing concern and discuss what actions can be taken to reduce and prevent strikes.

Seasonal Variability In Brown Tree Snake (Boiga Irregularis) Response To Lures, John A. Shivik, William G. Wright, Larry Clark

United States Department of Agriculture Wildlife Services: Staff Publications

In continuing investigations of brown tree snake, Boiga irregularis, attraction to carrion odor, we hypothesized that the attractiveness of live or dead and visually apparent or concealed lures varies seasonally. We determined that lure condition (live or dead mouse lures) and sensory cues (visually apparent or concealed lure) interact among wet and dry seasons. Concealed carrion lures were more effective during the dry season than the wet season, but the effectiveness of live mouse lures showed less seasonal variability. We identified weather variables that covary with observed seasonal trends in capture rates and investigated the influence of recent feeding …

Immunocontraception Of White-Tailed Deer With Gnrh Vaccine, Lowell A. Miller, Brad E. Johns, Gary J. Killian

United States Department of Agriculture Wildlife Services: Staff Publications

One of the most successful immunocontraceptive vaccines used for wildlife is porcine zona pellucida (PZP). Several authors have published on the use of PZP immunocontraceptive vaccines to immunosterilize white-tailed deer. This is the first long term study of the use of GnRH contraception of deer. This GnRH immunocontraceptive study was part of a multi-year White- Tailed deer infertility study on the deer herd at Pennsylvania State University, (PSU) University Park, Pennsylvania in cooperation with National Wildlife Research Center, (NWRC) Fort Collins, CO.

Reporting Bias In Bird Strikes At John F Kennedy International Airport, New York, 1979-1998, Scott C. Barras, Richard A. Dolbeer

United States Department of Agriculture Wildlife Services: Staff Publications

Bird-aircraft strike databases have been used to identify, monitor, and manage bird strike problems in the USA nationally and at individual airports. Up to 75% of all bird strikes that occur in the USA may not be reported by pilots or airport control tower personnel. Recent studies have suggested that individual airports may improve their strike reporting rates by having personnel regularly search runways for the remains of birds struck by aircraft. We analyzed a 20-year dataset of runway searches from John F. Kennedy International Airport (JFKIA) in New York to determine the degree of bias in reports of strikes …

Roles Of Odor, Taste, And Toxicity In The Food Preferences Of Lambs: Implications For Mimicry In Plants, Frederick D. Provenza, Bruce A. Kimball, Juan J. Villalba

United States Department of Agriculture Wildlife Services: Staff Publications

In the traditional sense, food ingestion consists of prehending, masticating, swallowing, and digesting plant matter. It is also possible to ingest plants without eating them. Volatile compounds are inhaled directly into the lungs and transported from the lungs into the bloodstream. Volatiles in high concentrations could presumably produce toxicosis, without an herbivore ever ingesting a plant in the customary sense. Volatile compounds may be aposematic, serving to warn potential predators of toxins in plants. We conducted three experiments to explore the roles of odor, taste, and toxicity in the food preferences of lambs. The first experiment determined if brief exposure …

Captive Great Blue Heron Predation On Farmed Channel Catfish Fingerlings, James F. Glahn, Brian Dorr, Mark E. Tobin

United States Department of Agriculture Wildlife Services: Staff Publications

In a series of experiments, we examined feeding behavior of captive great blue herons Ardea herodius and estimated their ability to affect commercial production of fingerling channel catfish Ictalurus punctatus. Specifically, we determined the following: (1) the biomass of channel catfish fingerlings necessary to maintain the body mass of wild-caught captive great blue herons, (2) capture rates of captive great blue herons foraging on channel catfish fingerlings, (3) evaluation of the losses of catfish fingerlings to heron predation, and (4) the effects of selected catfish pond conditions on heron capture rates and body mass changes. Consistent with previous studies, …

NEWSLETTER M Transcendentalist by L. Mikel Vause, Weber State University he term "transcendentalist" evokes an interesting image. Generally when one thinks of a transcendentalist, the image of a little brown-skinned mystic, sitting in lotus position chanting "ommm" comes to ihind. Although American transcendentalism certainly does have Far Eastern roots, one ascribing to that title is Br more likely to be found tramping around the back country rather than curled up on a mat contemplating the ilssence of existence. The founder of American transcendentalism is Ralph Waldo Emerson, "The Sage of Concord." It was Emerson who, with the publication of Nature …

The True Truth About Kgi And The Field Station, Paul Faulstich

Pitzer Faculty Publications and Research

There are multiple truths. One is the true truth. This truth remains the same no matter what anyone thinks or says about it. For example, it is true truth that we need oxygen. and that trees provide it. No matter what we think or say about it, this is the way it is. And, the Bernard Biological Field Station is habitat to threatened and endangered plants and animals. This, too, we know to be true.

The Massachusetts Environmental Industry: Facing The Challenges Of Maturity, Betty J. Diener, David Terkla, Erick Cooke

Management and Marketing Faculty Publication Series

For most of the past 20 years, the environmental industry has been a very significant one, both in Massachusetts and across the country. Some have placed it alongside the electronics, computer hardware, software, biotechnology, fiber optics, and composite materials industries as part of the high-technology sector that has diversified and strengthened the state’s economy. Nationally, environmental industry employment exceeded that of several major manufacturing industries, including chemicals, paper, and aerospace.

In the late 1990s, however, the momentum of the environmental movement began to wane. A decline in both employment and sales suggests that many of the most pressing environmental concerns …

Examination Of The Bureau Of Land Management's Implementation Of The Wild, Free-Roaming Horse And Burro Act At Red Rock National Conservation Area, Christine E. Brehm

UNLV Theses, Dissertations, Professional Papers, and Capstones

For unknown reasons horses went extinct on the North American continent approximately ten thousand years ago and were subsequently reintroduced by Spanish settlers in the 1400's. As European settlers moved westward, horses were perceived as competition for grasslands and their numbers were curtailed. Wild horses were granted Federal protection in 1959 with the passage of the 'Wild Horse Annie' law and further protected with the passage of the Wild, Free-Roaming Horse and Burro Act of 1971. Through the Department of the Interior, the Bureau of Land Management was charged with management of wild horses on public lands. Physical searches of …

Green Sea Turtle (Chelonia Mydas) Hatchlings Success: The Effects Of Artificial Lights And Other Human Impacts, Hui-Yu Tracy Liang

UNLV Theses, Dissertations, Professional Papers, and Capstones

Sea turtles appeared more than 200 million years ago in the late Triassic period. They grow very slowly, taking an average of 25 years to reach sexual maturity, with a life span averaging 40-50 years. From May to October green sea turtles (Chelonia mydas) emerge during the night and follow light cues toward the sea. Recently, beachfront development has increased hatchling mortality rate. When hatchlings emerge from nest, high densities of artificial lights lead them toward the land where they either desiccate and die, or are preyed upon. Short-wavelength high intensity light and the distance of artificial light are the …

Deposition And Uptake Availability Of Lead Shot For Waterfowl At Honeybee Pond Within The Overton Wildlife Management Area, Nevada, Usa, Jason Eckberg

UNLV Theses, Dissertations, Professional Papers, and Capstones

Lead shot has been banned for hunting waterfowl since 1974, but lead poisoning continues to be a major problem in many waterfowl habitats. In December of 1999, soil samples were collected from the Honeybee pond at the Overton Wildlife Management area to determine the lead pellet concentration and the availability of lead shot to waterfowl. There were no shot pellets recovered from the thirty-one samples taken from the pond. Based on this information waterfowl do not appear to be exposed to lead in the pond areas at OWMA.

Two Different Soil Sampling Techniques For Assessing Soil Lead Concentrations At The Overton Wildlife Management Area, Nevada, Kristen E. Falc

UNLV Theses, Dissertations, Professional Papers, and Capstones

During the summer of 1999, soil samples were taken from the Overton Wildlife Management Area (OWMA), located in the Moapa Valley of Clark County, Nevada. Although lead shot has been banned for the hunting of waterfowl since 1986, it is still legal for upland game hunting. The field sampled serves primarily as a dove hunting area and is cultivated. A large sample size was taken to indicate the short-term effects of the deposition of lead shot in the area and a small sample size, the long-term. Lead shot was recovered from 64% of the small samples and the estimated concentration …

The current recycling program on the University of Nevada Las Vegas (UNLV) campus does not have a special event recycling aspect. The purpose of this study was to develop a special event recycling program and make recommendations of how to effectively implement it on the UNLV campus. In order to develop this special event recycling program data was collected through surveys and a pilot study. The data collected was then used to formulate recommendations. Recycling two different kinds of events, a walk and a concert tested those recommendations. Waste stream analyses were done on each event. The waste stream diversion …

Multiple Source Pools And Dispersal Barriers For Galápagos Plant Species Distribution, J. Alan Yeakley, John F. Weishampel

Environmental Science and Management Faculty Publications and Presentations

We reexamined geographic factors explaining the number of plant species on islands in the Galápagos Archipelago. We hypothesized that plant species richness (S) was related to the number of source pools and that plant species dispersal preferentially followed direct, oceanic pathways. To test different dispersal pathways from multiple source pools, the total number of islands within a given dispersal radius (i) was posed as the sum of the number of line-of-sight islands (C_i) and of the number of islands without line-of sight connection (B_i). In partial regression analyses, controlling for nearest island area (A₂) …

Water Supply Sustainability Through Water Banking, Linda I. Gordan

Water Resources Professional Project Reports

Until relatively recently, the preferred approach to satisfying the water needs of growing communities has been to develop untapped supplies. As new water-supply sources have become less accessible, and as developing then has become more expensive and less acceptable environmentally, managing demand and enabling voluntary water reallocation have taken on increasing importance. Demand management and water marketing could be very important in coping with increasing demand and limited supplies, both because they promote efficiency and because they enable a considerable amount of flexibility in water resource management.

Repellents To Reduce Cable Gnawing By Wild Norway Rats, Stephen A. Shumake, Ray T. Sterner, Stanley E. Gaddis

United States Department of Agriculture Wildlife Services: Staff Publications

Rodents gnaw communications and power cables, resulting in service interruptions, fires, and other safety concerns. Commensal rodents such as the Norway rat (Rattus norvegicus) have been implicated in many of these situations. Two chemical repellents (capsicum oleoresin+apsaicin and denatonium benzoate) at 2.0% mass/mass concentrations in a polybutene carrier (Indopol-controlw) ere evaluated for repellent efficacy compared to a plastic mesh physical barrier material (Vexa*) and the polybutene carrier (placebo) alone using groups of individually caged wild Norway rats. The materials were applied to short lengths of communications cable (RG-8U) with the repellents enclosed in electrical shrink tubing around the …

Long-Term Spatial Stability Of Coyote (Canis Latrans) Home Ranges In Southeastern Colorado, Ann M. Kitchen, Eric M. Gese, Edward R. Schauster

United States Department of Agriculture Wildlife Services: Staff Publications

Long-term stability of territorial boundaries has not been well documented in canids. To evaluate the prevalence of long-term spatial stability of coyote (Canis latrans) home ranges, we compared the overlap of territorial boundaries and the spatial distribution of telemetry locations of packs in southeastern Colorado. From August 1983 to July 1988 (period l), 16 coyotes from six packs were radio-tracked. From April 1996 to August 1997 (period 2), 12 coyotes from six packs were captured and tracked in the same area. Mean percentage of overlap of pack ranges was 89.8 ± 8.3% (+SD) for period 1 ranges over …
