Serologic Survey For Diseases In Free-Ranging Coyotes (Canis Latrans) From Two Ecologically Distinct Areas Of Utah, Wendy M. Arjo, Eric M. Gese, Cassity Bromley, Adam Kozlowski, Elizabeth S. Williams Apr 2003

Serologic Survey For Diseases In Free-Ranging Coyotes (Canis Latrans) From Two Ecologically Distinct Areas Of Utah, Wendy M. Arjo, Eric M. Gese, Cassity Bromley, Adam Kozlowski, Elizabeth S. Williams

United States Department of Agriculture Wildlife Services: Staff Publications

The influence of habitat and associated prey assemblages on the prevalence of canine diseases in coyotes (Canis latrans) has received scant attention. From December 1997 through December 1999, we captured 67 coyotes in two ecologically distinct areas of Utah (USA): Deseret Land and Livestock Ranch and US Army Dugway Proving Ground. These areas differ in habitat and prey base. We collected blood samples and tested for evidence of various canine diseases. Prevalence of antibodies against canine parvovirus (CPV) was 100% in the Deseret population and 93% in the Dugway population. All juveniles in both populations had been exposed. …


An Examination Of Modulation Of Feeding Behavior In The Nurse Shark Ginglymostoma Cirratum (Bonaterre 1788), Michael Matott Apr 2003

An Examination Of Modulation Of Feeding Behavior In The Nurse Shark Ginglymostoma Cirratum (Bonaterre 1788), Michael Matott

USF Tampa Graduate Theses and Dissertations

The ability of an organism to modulate its feeding behavior is an important focus of feeding ecology studies. Modulation is the ability to distinctly and consistently alter a behavior to accommodate different stimuli. The goal of this study was to examine the ability of the nurse shark Ginglymostoma cirratum to modulate its food capture behavior with different sizes and types of food items. This was carried out through kinematic and electromyographic analysis.

Eight sub-adult specimens of G. cirratum were filmed feeding on two different food types (squid and fish) and sizes (gape size and larger than gape size). Filming consisted …

In an open letter published last year in the New York Times, 21 distinguished scientists (including three Nobel laureates) criticized Japan's program of scientific research whaling, noting its poor design and unjustified reliance upon lethal sampling. In a recent Forum article in BioScience, Aron, Burke, and Freeman (2002) castigate the letter's signers and accuse them of meddling in political issues without sufficient knowledge of the science involved in those issues.


Biology And Ecologyof Epigean Crayfish That Inhabit Everglades Environments Procambarus Alleni (Faxon) And Procambarus Fallax (Hagen), Peggy G. Vanarman Mar 2003

Biology And Ecologyof Epigean Crayfish That Inhabit Everglades Environments Procambarus Alleni (Faxon) And Procambarus Fallax (Hagen), Peggy G. Vanarman

HCNSO Student Theses and Dissertations

Two species of epigean crayfish, Procambarus alleni (the Everglades crayfish) and Procambarus fallax (slough crayfish), may be keystone species that inhabit wetlands in south Florida and the Everglades. Recent field studies showed that although these two species occur in sympatric and syntopic distribution, Everglades crayfish prefer shallow water and short hydroperiod conditions, whereas slough crayfish prefer areas that are more permanently flooded (Hendrix 2000). Slough crayfish have invaded some areas within the range occupied by Everglades crayfish, and may be the more successful competitor. Because of their critical role throughout the trophic structure of Everglades wetlands, shifts in relative abundance …

Scavenging By Vertebrates: Behavioral, Ecological, And Evolutionary Perspectives On An Important Energy Transfer Pathway In Terrestrial Ecosystems, Travis L. Devault, Olin E. Rhodes Jr., John A. Shivik Feb 2003

Scavenging By Vertebrates: Behavioral, Ecological, And Evolutionary Perspectives On An Important Energy Transfer Pathway In Terrestrial Ecosystems, Travis L. Devault, Olin E. Rhodes Jr., John A. Shivik

United States Department of Agriculture Wildlife Services: Staff Publications

Carrion use by terrestrial vertebrates is much more prevalent than conventional theory implies, and, rather than a curiosity of animal behavior, is a key ecological process that must be accounted for. Human aversion to rotted substances and difficulties associated with identifying scavenged material in studies of food habits have contributed to the relative lack of information concerning scavenging behavior in vertebrates. Several lines of evidence, however, suggest that carrion resources are more extensively used by vertebrates than has been widely assumed: 1) a substantial number of animals die from causes other than predation and become available to scavengers, 2) a …


Characteristics Of Current And Historical Kit Fox (Vulpes Macrotis) Dens In The Great Basin Desert, Wendy M. Arjo, Tim J. Bennett, Adam J. Kozlowski Feb 2003

Characteristics Of Current And Historical Kit Fox (Vulpes Macrotis) Dens In The Great Basin Desert, Wendy M. Arjo, Tim J. Bennett, Adam J. Kozlowski

United States Department of Agriculture Wildlife Services: Staff Publications

We examined the ecological and physical characteristics of den sites for 13 adult kit fox (Vulpes macmtis) in western Utah from December 1998 to February 2001. We also compared current and historical den distribution among habitat types. The number of den sites used was not influenced by home-range size (P = 0.11) or season (P = 0.40), but was influenced by geographical area. Home-range size was smallest (P = 0.007) and the number of dens used was greatest (P = 0.009) in mountainous areas. Ecological and physical characteristics of single-use dens (n = …

Habitat Utilization By Bottlenose Dolphins (Tursiops Truncatus) In Biscayne Bay, Florida, Christine A. Hudak Feb 2003

Habitat Utilization By Bottlenose Dolphins (Tursiops Truncatus) In Biscayne Bay, Florida, Christine A. Hudak

HCNSO Student Theses and Dissertations

Bottlenose dolphins (Tursiops truncatus) exhibit variable distribution patterns, depending upon their geographic location. Habitat utilization patterns in Biscayne Bay, Florida, were examined using the Biscayne Bay Bottlenose Dolphin Photo-ID database obtained from the National Oceanic and Atmospheric Administration (NOAA) Southeast Fisheries Science Center (SEFSC) Miami Laboratory. Habitat coverages in Biscayne Bay were obtained from the Atlas of Marine Resources Version 1.3B CD and the Biscayne Bay National Park CD. Dolphin sightings were overlaid on the habitat coverages using GIS Arcview software.

The effects of habitat, season, behavior, zone (sectioned area of Biscayne Bay), and depth on patterns …

Nesting Phenology And Productivity Of Birds In The White And Inyo Mountains, California, As Assessed With Nest-Boxes, Linnea S. Hall, Michael L. Morrison Jan 2003

Nesting Phenology And Productivity Of Birds In The White And Inyo Mountains, California, As Assessed With Nest-Boxes, Linnea S. Hall, Michael L. Morrison

Western North American Naturalist

Nest-boxes were monitored from 1988 to 1992 on 5 grids in the pinyon-juniper (Pinus-Juniperus) woodlands of the White and Inyo Mountains, California, to determine breeding phenology and productivity of cavity-nesting birds, and characteristics of used and non-used nest-boxes. We found a total of 112 nests of 6 species. Bewicks Wrens (Thryomanes bewickii; 64 nests), Mountain Chickadees (Poecile gambeli; 18), Ash-throated Flycatchers (Myiarchus cinerascens; 12), and Juniper Titmice (Baeolophus ridgwayi; 11) were the most common species utilizing the boxes. Nest phenology and numbers of young were similar to values reported elsewhere …

The Hanford 300 Area Cleanup Plan – Insufficient, Dangerous, And Against Best-Known Findings, Columbia Riverkeeper, Greg Debruler Jan 2003

The Hanford 300 Area Cleanup Plan – Insufficient, Dangerous, And Against Best-Known Findings, Columbia Riverkeeper, Greg Debruler

Columbia Riverkeeper

This report analyzes the decision to limit the cleanup of the Hanford 300 Area to “Industrial Use” only. This decision raises legitimate concerns that providing such a minimal cleanup may be insufficient for protecting the Columbia River ecosystem and natural environment surrounding the Hanford site throughout the extraordinarily long life span of the hazardous waste. This report also provides a background on how the cleanup decision was made, the legal drivers, and an analysis of the risk assessment processes used in reaching the decision.

Given the multiple regulations, complex issues, and extensive technical data, it may be very difficult for …

Wild Horses And Burros In The United States, Allen T. Rutberg Jan 2003

Wild Horses And Burros In The United States, Allen T. Rutberg

State of the Animals 2003

Treatment of wild horses and burros has improved remarkably over the last fifty years. In the mid-twentieth century, free-ranging horses and burros suffered horribly at the hands of “mustangers” who captured them at will and whim, sometimes using the most brutal of techniques, including aerial pursuit and shooting or crippling key herd members. The horses were packed into livestock trucks hurt, bleeding, and exhausted, and shipped to slaughter without stopping for rest or watering (Ryden 1999). Unprotected by law, only the good will of a few ranchers protected these abused animals. Public awareness of the plight of the wild horses …

Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick Jan 2003

Spatial Heterogeneity Of Soil Nutrients, Nitrogen Dynamics, And Vegetation In A 3rd Order Stream Floodplain In Southwestern West Virginia, David Allen Dick

Theses, Dissertations and Capstones

Soil processes often exhibit spatial heterogeneity within ecosystems and this heterogeneity may influence community structure. This study was conducted to determine spatial patterns and variability of soil nutrients and plant communities within different vegetation types in a stream floodplain in southwestern West Virginia. One 5-m × 5-m site was established in each of three vegetation/drainage types: pasture (PA), old field (OF), and wetland scar (SC). Pasture and SC sites were located ~25 m apart on flat bottomland; the OF site was located on a moderate slope 6.3 m above bottomland, ~200 m from PA and SC. A 10-m × 1-m …
