Five study sites located in or adjacent to the Otter Creek National Wilderness Area, Monongahela National Forest, Randolph County, West Virginia, were monitored to determine nesting habits and length of incubation and larval periods in Hemidactylium Time of breeding was determined by spermatogenic wave analysis and time of egg deposition was determined by examination of ovarian follicles and field observations of gravid females migrating to nest sites. Breeding occurred in autumn and again …

Ecological Life History Of Crangonyx Pseudogracilis Bousfield (Crustacea: Amphipoda) In The Green Bottom Wildlife Management Area, Cabell County, West Virginia, Andrea Leigh Henry

Theses, Dissertations and Capstones

Although the genus Crangonyx has been studied in the Appalachian area, most of this work has concentrated on subterranean species. A Crangonyx pseudogracilis population from the Green Bottom Wildlife Management Area (GBWMA), Cabell County, West Virginia was sampled weekly from March 1995 through July 1996 to investigate the ecological life history of the amphipod. A total of 1508 amphipods were collected. Amphipods were present in the study sites from November through July, at which time they migrated to deeper waters. Crangonyx pseudogracilis had a one year life cycle and bred from November to May. Adult amphipods began to die off …

Natural History Of The Red-Spotted Newt, Notophthalmus Viridescens Viridescens (Rafinesque), In West Virginia, Jennifer M. Piascik

Theses, Dissertations and Capstones

Many studies have been conducted on Notophthalmus viridescens viridescens but none have occurred in West Virginia. There are variations in the life history of newts depending on location. In this study, I studied a population of newts in Wayne County, West Virginia from February 1996 to June 1997. I examined population structure, seasonal activity, and reproductive biology.

The population structure can be divided into four classes: egg, larvae, eft, and adult. Eggs at Shoals were deposited in mid-May and larvae were present from mid-June to early September. Larvae began to transform at an approximate total length of 32.8 mm. Red …

Observations On Reproduction, Isozyme Patterns, And Meristics In Mosquitofish (Pisces: Poeciliidae) From West Virginia, Matt Mcreynolds

Theses, Dissertations and Capstones

Prior to 1988, two subspecies of the mosquitofish Gambusia affinis (G. a. affinis and G. a. holbrooki) were recognized along the Gulf and Atlantic Coasts of the United States. Based on electrophoretic analysis, subsequent investigators recognized G. holbrooki and G. affinis as separate species. Populations in drainages west of Mobile Bay were considered G. affinis, and those east of this divide being G. holbrooki. The only mosquitofish population in West Virginia is found in the Meadow River wetlands (1392 ha). This wetland complex is located at the western end of Greenbrier County in the Allegheny Mountain Province. …

Diet And Growth Of Larval And Juvenile Grass Pickerel, Esox Americanus Vermiculatus, And Central Mudminnow, Umbra Limi, In The Green Bottom Wildlife Management Area, Cabell County, West Virginia, Erica Midkiff

Theses, Dissertations and Capstones

The grass pickerel, Esox americanus vermiculatus, is listed as Undetermined on the Vertebrate Species List of Concern in West Virginia. The central mudminnow, Umbra limi, is a disjunct population in Green Bottom Swamp. The lentic, vegetated areas that are required for spawning for the grass pickerel and the central mudminnow have been reduced by residential, agricultural, and industrial developments. Green Bottom Swamp, a naturally occurring wetland of 58 ha, and a nearby mitigated wetland of 29 ha, provides spawning habitat for the grass pickerel and the mudminnow. Fishes were collected in beds of Potamogetan crispus and Ceratophyllum demursum …

An Immunomodulating Mycotoxin Interferes With The Development Of Autoimmune Diabetes In Diabetes-Prone Bb/Wor Rats, Honggang Liu

Theses, Dissertations and Capstones

Various fungal products have immunomodulating activity and some have been studied regarding prevention of transplantation rejection. Prior to this investigation, the mycotoxin, gliotoxin (GT), has never been investigated as an immunotherapeutic drug for autoimmune disease. GT is a fungal secondary metabolite and a member of the epipolythiodioxopiperazine (ETP) family which has been shown to inhibit phagocytosis, induction of cytolytic T cells and the proliferation of T cells following mitogen stimulation. GT also induces in vitro apoptosis in certain immune cell types. More importantly, GT exhibits selective activity towards cells of hemopoietic origin.

Autoimmune diseases are disorders caused by immune responses …

Nesting Piping Plover And Least Tern On The Kansas River, William H. Busby, Daniel W. Mulhern, P. Gregory Kramos, David A. Rintoul, William C. Tuttle

United States Fish and Wildlife Service: Publications

A portion of the Kansas River in northeastern Kansas was surveyed by boat and air in 1996 and 1997 for nesting colonies of piping plover (Charadrius melodus) and least tern (Sterna antillarum). Both species were found breeding on sandbars at a total of five sites along a 30-km reach of the Kansas River. In 1996, at least two breeding pair of piping plovers and seven breeding pair of least terns were documented. In 1997, at least one pair of piping plovers and five pairs of least terns bred. These are the first known breeding records for …

1997 North American Conference On The Monarch Butterfly

United States Fish and Wildlife Service: Publications

The Monarch Butterfly has attracted much interest because it is unique not only among insects, but among all living things. The largest Monarch population emerges in the central and northeastern United States and Canada and flutters its way south several thousand kilometers to remote fir forests in the central mountains of Mexico. There they overwinter in about twenty compact colonies—sometimes numbering in the tens of millions—often within a stone’s throw of local subsistence farms sustaining Mexican campesinos (small-scale farmers) and indigenous peoples. In the spring, the northward trek begins, often with an additional generation being required to reach the northern …

Environmental Contaminants In The Aquatic Bird Food Chain Of An Oil Refinery Wastewater Pond, Pedro Ramirez Jr.

United States Fish and Wildlife Service: Publications

Bird mortalities have been documented in oilfield waste pits in Wyoming and various other oil-producing states in the western United States. In the semi-arid West, migratory birds mistake wastewater ponds or pits for wetlands. Most refineries use large ponds to contain their wastewater. One refinery in Casper, Wyoming actively discharged refinery wastewater into a closed basin, Soda Lake. This created a wetland that attracts numerous aquatic birds, in particular, nesting colonies of gulls (Larus spp.), terns (Sterna spp.), double-crested cormorants (Phalacrocorax auritus), eared grebes (Podiceps nigricollis), dabbler ducks (Anas spp.) and American avocets ( …

Skeletochronological Study Of Adult Spiny Softshell Turtles (Apalone Spinifera) From Northeastern Arkansas, Stanley E. Trauth, Hilary J. Worley

Journal of the Arkansas Academy of Science

Skeletochronological techniques were used to examine age and growth in adult spiny softshell turtles {Apalone spiniferd) from northeastern Arkansas. The diaphyseal region offemurs of 24 specimens (8 mars mars; 16 venus venus) was excised, decalcified in weak hydrochloric acid, and histologically prepared for light microscopy. Skeletal growth was determined from histosectioned bones by measuring femur diameters as well as by counting lines of arrested growth (LAGs) that appear between distinct periosteal layers (marks of skeletal growth =MSGs) laid down during a single growing season. Although significant positive correlations were found between carapace length (CL) and femur diameter in both males …

In Vivo Incorporation Of Tritium To Measure Lipogenesis In Red Skeletal Muscle: Significance Of A Nonlipogenic Diet In La/N-Fa(K)("Corpulent") And Zucker Fa Rat Strains, Karin Traci Mann

Theses, Dissertations and Capstones

Skeletal muscle lipogenesis in rodents may equal that of liver but its importance in the obese animals is not known. We evaluated the rate of fatty acid and triglyceride synthesis and storage content in red skeletal muscles, liver, inguinal fat, and retroperitoneal fat of the LA/N-fa^k (“corpulent”) and Zucker fa obese rat strains. Obese-lean pairs of both rat strains, weaned at 32 days, fed a nonlipogenic diet (54% starch for 21 days) were either dosed with 2 µCi 3H-H² O per gram of body weight and tested after 60 minutes for whole body 3H-incorporation into fatty acids and …

Fish Community Of Indian Bayou, A Coastal Plain Stream Of Remarkable Species Richness In The Lower White River Drainage Of Arkansas, Thomas M. Buchanan

Journal of the Arkansas Academy of Science

It is increasingly important to identify unique aquatic ecosystems in the coastal plain lowlands of Arkansas, because of the extensive human-induced alteration of aquatic habitats and loss of fish diversity in that region. Indian Bayou, part of a small (103 km2 ), chute-fed drainage system off the lower White River in Monroe County, Arkansas, has a fish community that is unique among Delta streams in darter (Percidae) species richness. Twenty-five fish samples collected by seine and rotenone from the Indian Bayou drainage system over an 18-year period produced 62 fish species, including 13 darter species. The fish community at one …

An Analysis Of The Variation Within Cratoxylum Arborescens (Clusiaceae) In Malesia, A.C. Church, P.F. Stevens

Biology Department Faculty Works

The variation within the widespread West Malesian species Cratoxylum arborescens (Vahl) Blume was analyzed and three distinctive variants were found. These are recognized formally as varieties, var. arborescens, var. miquelii King, and var. borneense A.C. Church & P.F. Stevens. A key and full descriptions are given. The characters employed to delimit the three taxa are discussed and the selection of varietal rank is justified.

An Investigation Of Irrigation-Related Contaminants In Water, Bottom Sediment, And Biota From Goshen County, Wyoming., Kimberly Dickerson, Pedro Ramirez Jr.

United States Fish and Wildlife Service: Publications

We conducted a comprehensive evaluation of trace element concentrations in water, sediment, aquatic vegetation, aquatic invertebrates, waterbird eggs, and fish resulting from irrigation drainwater during 1995 in Goshen County, Wyoming. We also analyzed waterbird eggs and fish from this area for organochlorine residues and attempted to determine the nesting success of various waterbirds.

Boron concentrations were elevated (>300 ug/g dry weight) in aquatic vegetation above concentrations shown to adversely affect sensitive waterfowl; however, these concentrations are similar to those found in aquatic vegetation sampled in other areas throughout Wyoming. Mercury concentrations in aquatic vegetation, aquatic invertebrates, and fish were …

Preference For Flavoured Foods By Lambs Conditioned With Intraruminal Administration Of Nitrogen, Juan J. Villalba, Frederick D. Provenza

Behavioral Education for Human, Animal, Vegetation, and Ecosystem Management (BEHAVE)

We suggested that food preference depends on the interplay between flavour and post-ingestive effects, and we predicted that protein-restricted lambs would acquire preferences for foods paired with supplemental sources of N, including urea (Expts 1 and 2), casein (Expt 3), and gluten (Expt 4). In each experiment, twenty lambs, in two groups of ten, were conditioned as follows: on odd-numbered days, lambs in group 1 received wheat straw (Expts 1, 3, and 4) or ground barley (Expt 2) flavoured with a distinctive flavour, and lambs in group 2 received the same food but with a different flavour. On even-numbered days, …

Preference For Wheat Straw By Lambs Conditioned With Intraruminal Infusions Of Starch, Juan J. Villalba, Frederick D. Provenza

Behavioral Education for Human, Animal, Vegetation, and Ecosystem Management (BEHAVE)

We hypothesized that feed preference depends on the interplay between flavour and postingestive effects, and we tested two predictions based on this hypothesis: (1) lambs acquire preferences for poorly nutritious feeds paired with starch; and (2) preferences persist when starch is no longer administered. Twenty lambs were randomly allocated to two groups and conditioned as follows: on odd-numbered days, lambs in group 1 received onion-flavoured wheat straw and lambs in group 2 received oregano-flavoured wheat straw. On even-numbered days, the flavours were switched and starch (2.5-9.4% of the digestible energy received/d) was infused into the rumen of all animals during …

All HMC Faculty Publications and Research

Here, we report evidence of predation on Xantusia vigilis by Sceloporus magister. We collected a yearling female S. magister (71 mm SVL, mass = 13.6 g) on 24 July 1996, 5 km SE of Llano, Los Angeles County, California, USA (34°29'N, 117°46'W, elevation 1120 m). In the laboratory, on 29 July, the S. magister deposited a fecal pellet that contained part of a Xantusia vigilis body, including sections of dorsal and ventral integument and both hind limbs.

Western Australian Fisheries - At A Glance (1997), Fisheries Department Of Western Australia

Fisheries Published Reports

Western Australia's fisheries are the envy of the world. The calibre of our research and management, and the skills of our fishermen, are recognised as second to none. We have pristine oceans and waterways from which we draw fish and fish products of the very best quality.

But while WA ranks as Australia's leading producer and exporter of fish and aquaculture products, we are not resting on our laurels. A major review of fisheries administration has cemented environmental and economic sustainability as the key management objectives, and industry now has greater scope for improving its competitiveness by pursuing new marketing …

Habitat Use By Migrant Whooping Cranes In Saskatchewan, Brian W. Johns, Eric J. Woodsworth, Ed A. Driver

Proceedings of the North American Crane Workshop

We investigated habitat use by migrating whooping cranes (Grus americana) in Saskatchewan between 1986 and 1990. At foraging and roosting sites and a sample of randomly selected sites we measured various habitat parameters. Palustrine and lacustrine wetlands were the most frequently used wetlands. Temporary and seasonal wetlands were the primary roost habitat during spring migration, and semi-permanent and permanent wetlands were frequently used during the fall. Cranes were attracted to areas of higher than average wetland density. Land use within 2 km of roost sites was intensively modified by man. Cereal crops were the most used feeding areas. …

Availability Of Stopover Habitat For Migrant Whooping Cranes In Nebraska, Dale W. Stahlecker

Proceedings of the North American Crane Workshop

Four stratified random samples of 512 National Wetland Inventory (NWI) maps within the central Nebraska portion of the Wood Buffalo-Aransas whooping crane (Grus americana) migration corridor were used to evaluate the availability of wetland roost sites. Wetlands were eliminated as potential roosts if visibility was obscured by vegetation or slope, if certain human activities occurred within 100-800 ro, or if water < 30 em deep was not available. Seasonal emergent wetlands, available as roosts primarily in spring, dominated all samples, particularly in the nortb. Sixty-five percent of all wetlands >0.04 ha passed map review and 52 % passed when ground-truthed. NWI map review was a good predictor of both suitability (63 % correct) and unsuitability (73 % correct). More than one-half of all open and emergent …

Woody Vegetation Expansion And Continuing Declines In Open Channel Habitat On The Platte River In Nebraska, Paul J. Currier

Proceedings of the North American Crane Workshop

Aerial videography in 1988 and 1994 of the same selected segments of the Big Bend reach of the Platte River in central Nebraska was compared. During this 6-year period, channel area declined 4 to 41 % (median 26%). In river segments where the channel had already narrowed significantly and at sites where channel habitat is actively managed declines were less (17-18%). These substantial changes occurred during a time that included a relatively low flow period (1990-92). Flows during the summer gertttination and establishment period (mid-May through August) for cottonwood (Populus deltoides) and willow (Salix spp.), the …

Home Range And Habitat Use By Isolation-Reared Sandhill Cranes, Wenrui Duan, Theodore A. Bookhouts, Richard P. Urbanek

Proceedings of the North American Crane Workshop

We isolation-reared, placed radio transmitters on, and released 38 greater sandhill cranes (Grus canadensis tabida) on Seney National Wildlife Refuge (Seney) in 1988-90 to develop procedures for initiating new populations of cranes. Here we report on habitat selection by breeding birds with functional radio transmitters. Home ranges established by 6 cranes in 1992, when they were 2 to 4 years old, averaged 199±50.8 (SE) ha (harmonic mean method, 75 % utilization) and were of 2 types: feeding grounds separated from nesting habitat and feeding grounds adjacent to nesting habitat. Home ranges consisted of 36% emergent palustrine wetlands, 28% …

Recent Advances In Scheduling Strategies And Practical Techniques In Crane Artificial Insemination, Scott R. Swengel, Monica L. Tuite

Proceedings of the North American Crane Workshop

We analyzed fertility patterns of 339 eggs laid 1985-93 at the International Crane Foundation by cranes whose sole means of fertility was artificial insemination (AI). Ten of 15 crane species were studied. Fertility rates increased significantly (P < 0.05) with (I) higher sperm density, (2) greater sperm motility, and (3) 2 vs. 1 vs. 0 inseminations 4-7 days before oviposition. Semen sample size was inversely related to sperm density and had no strong relationship with egg fertility. Inseminations less than 2.5-3.0 days before an egg is laid are probably too late to contribute to fertilizing the egg but may contribute substantially to fertilizing the next egg. We also describe practical knowledge gained during the past 10 years that apply to certain species or situations. Wattled cranes (Bugeranus carunculatus) have a long fertile period post-AI (up to 16 days), but may require more careful methods and special AI scheduling strategies. We also describe techniques for AI just after oviposition that are especially beneficial for Siberian cranes (Grus leucogeranus), and methods for maximizing sample delivery to the female.
