Forecasting Forage Yield On Clayey Ecological Sites In Western South Dakota Using Weather Data, Alexander J. Smart, Barry H. Dunn, Lan Xu, Patricia S. Johnson, Roger N. Gates

South Dakota Beef Report, 2005

The ability to forecast annual forage yield from weather data would be useful for making appropriate adjustments to stocking rates in order to achieve or maintain desired plant communities. Our objective was to determine the relationship between weather variables and annual forage yield from three distinct plant communities on clayey ecological sites in western South Dakota. Forage yield and weather data were collected from 1945 through 1960 at the Cottonwood Range and Livestock Research Station, in western South Dakota. Pastures stocked at 0.25, 0.40, and 0.60 AUM/acre from 1942 to 1960 developed into western wheatgrass-dominated, western wheatgrass-shortgrass co-dominated, and shortgrass …

Home Range And Behavior Of The Timber Rattlesnake (Crotalus Horridus), Jennifer P. Adams

Theses, Dissertations and Capstones

Seventeen timber rattlesnakes were surgically implanted with radio transmitters and subsequently radio-tracked to determine the home range and behavior, as well as cause-specific mortality, of timber rattlesnakes on production forests in Randolph County, West Virginia. Mean home range sizes were 94.3 ha, males; 31.2 ha, nongravid females; 8.5 ha, gravid females; and 44.7 ha, among sex classes. Among sex classes, the mean daily movement rate was 20.2 mper day; the mean maximum known distances from den sites was 1110.2 m; the mean distance from den sites was 514.2 m; and the mean total distance moved was 2852.9 m. Mean active …

Habitat Analysis By Hierarchical Scheme And Stream Geomorphology, James B. Spence

Theses, Dissertations and Capstones

A study was undertaken to classify eight stream reaches in the North Branch of the Potomac River watershed and determine if geomorphologic differences influenced the availability of fish habitat structure and fish density. Stream reaches were classified using Rosgen Level II (1996) methods, and fish habitat was determined using Hydraulic Channel Unit (HCU) classification based on a method modified from Bisson et al. (1982). Other habitat variables were also studied such as stream shading and physical habitat based on the Rapid Bioassessment Protocol (Barbour et al. 1999). Despite the differences in HCU density between sites, HCU density did not influence …

Comparisons Of Morphology And Reproductive Status Of Plethodon Glutinosus At High, Middle, And Low Elevations In West Virginia, Cynthia F. Lucas

Theses, Dissertations and Capstones

Plethodon glutinosus populations in West Virginia were looked at in three different elevations. Objectives were to determine if there is enough difference in elevation to cause different populations to vary in morphology and reproduction. Nine morphological measurements were taken to represent both size and proportional shape. Sexual dimorphism was found in all measurements only in low elevations, males being larger (p<0.001-p=0.041). Mean measurements between the three elevations showed significant differences (p<0.005) in all measurements excluding head width, tail length, and 3rd digit length. Salamanders were dissected; testes and vasa deferentia were removed from males and ovaries with follicles were removed from females. Results showed males in lower and middle elevations deposit spermatophores May-July. Low sample sizes in higher elevations provided inconclusive results. Females of lower elevations lay eggs early-mid summer. Middle and higher elevations results revealed a likely spring oviposition, or possibly a fall oviposition.

Aging Affects Stretch-Induced P70s6k And 4e-Bp1 Phosphorylation In Fast- And Slow-Twitch Muscle, Sreevani Uddemarri

Theses, Dissertations and Capstones

In the present investigation we compare the expression, basal activation and the ability of muscle stretch to activate the p70^S6k pathway in the fast-twitch extensor digitorum longus (EDL) and slow-twitch soleus of adult (6 mo. old), aged (30 mo. old) and very aged (36 mo. old) Fischer 344 x Brown Norway rats. Immunoblotting demonstrated that the tissue content of mTOR, p70^S6k, 4E-BP1 and GSK-3β decreased in the EDL and soleus in aged rats, while SHP-2 increased in the EDL and decreased in the soleus when compared to adult rats. Basal phosphorylation of 4E-BP1 increased in both the …

The Reproductive Cycle Of The Thorny Skate (Amblyraid Radiata) In The Western Gulf Of Maine, James A. Sulikowski, Jeff Kneebone, Scott Elzey, Joe Jurek, Patrick D. Danley, William Huntting Howell, Paul C.W. Tsang

Biological Sciences

The thorny skate (Amblyraja radiata) is a large species of skate that is endemic to the waters of the western north Atlantic in the Gulf of Maine. Because the biomass of thorny skates has recently declined below threshold levels mandated by the Sustainable Fisheries Act, commercial harvests from this region are prohibited. We have undertaken a comprehensive study to gain insight into the life history of this skate. The present study describes and characterizes the reproductive cycle of female and male thorny skates, based on monthly samples taken off the coast of New Hampshire, from May 2001 to May 2003. …

Age And Growth Estimates Of The Thorny Skate (Amblyraja Radiata) In The Western Gulf Of Maine, James A. Sulikowski, Jeff Kneebone, Scott Elzey, Joe Jurek, Patrick D. Danley, William Huntting Howell, Paul C.W. Tsang

Biological Sciences

The northwest Atlantic population of thorny skates (Amblyraja radiata) inhabits an area that ranges from Greenland and Hudson Bay, Canada, to South Carolina. Despite such a wide range, very little is known about most aspects of the biology of this species. Recent stock assessment studies in the northeast United States indicate that the biomass of the thorny skate is below the threshold levels mandated by the Sustainable Fisheries Act. In order to gain insight into the life history of this skate, we estimated age and growth for thorny skates, using vertebral band counts from 224 individuals ranging in size from …

Endangered And Threatened Wildlife And Plants; Determination Of Endangered Status For The Salt Creek Tiger Beetle (Cicindela Nevadica Lincolniana)

United States Fish and Wildlife Service: Publications

We, the U.S. Fish and Wildlife Service (Service), determine endangered status for the Salt Creek tiger beetle (Cicindela nevadica lincolniana), pursuant to the Endangered Species Act (Act) of 1973, as amended (Act). This species is endemic to the saline wetlands of eastern Nebraska (NE) and associated streams in the northern third of Lancaster County and southern margin of Saunders County. Only three small populations of this subspecies remain, and the known adult population size in 2005 was only 153 individuals. This final rule extends Federal protection and recovery provisions of the Act to the Salt Creek tiger beetle.

Contaminant Exposure And Reproductive Health Of Sandhill Cranes In The Central Platte River Valley, Nebraska., Matthew S. Schwarz, Christina D. Lydick, Karen J. Nelson, Timothy S. Gross

United States Fish and Wildlife Service: Publications

The central Platte River Valley provides crucial staging habitat for the endangered whooping crane (Grus americana) and the mid-continent population of sandhill cranes (Grus canadensis). Platte River flow depletions and the conversion of native wet meadows for agriculture and other purposes has decreased the cranes natural habitat in the central Platte River Valley, and waste corn now makes up most of the cranes diet while they are in the Valley.

The purpose of this research was to measure organochlorine, elemental contaminant, and pesticide exposure to sandhill cranes from the central Platte River Valley, and to evaluate their reproductive condition. Pesticides …

Secondary Lead Poisoning In Golden Eagle And Ferruginous Hawk Chicks Consuming Shot Black-Tailed Prairie Dogs, Thunder Basin National Grassland, Wyoming, Robert M. Stephens, Aran S. Johnson, Regan Plumb, Kimberly K. Dickerson, Mark C. Mckinstry, Stanley H. Anderson

United States Fish and Wildlife Service: Publications

Recreational shooting of black-tailed prairie dogs (Cynomys ludovicianus) is a common activity at Thunder Basin National Grassland (TBNG), Wyoming. The prairie dog carcasses left in the area are scavenged by coyotes (Canis latrans), raptors, and other animals. These scavengers are susceptible to lead (Pb) poisoning if they consume Pb bullet fragments or Pb shot when scavenging the shooter-killed prairie dogs. In 2000, a local rehabilitator noted an increase of Pb poisoning cases in raptors (L.Layton, pers. comm. 3/30/01) from the area. We collected several shooter-killed prairie dog carcasses from TBNG for determining if Pb fragments remained …

All HMC Faculty Publications and Research

In the North American southwest, leopard lizards (genus Gambelia) are characteristically ground dwelling (Stebbins 2003. A Field Guide to Western Reptiles and Amphibians, 3rd ed., Houghton-Mifflin, New York. 533 pp.; Smith 1946. Handbook of Lizards, Comstock Publishing Co., Ithaca, New York. 557 pp.). In G. wislizenii, climbing is not mentioned in several substantive ecological studies of this species (Parker and Pianka 1976. Herpetologica 32:95-114; Tanner and Krogh 1974. Herpetologica 30:63-72), and to our knowledge, only a few seconds exist of climbing in this species. Clark (1974. Trans. Kansas Acad. Sci. 77:68) observed a G. wislizenii perched 30 cm …

Fishes Of The Pine Bluff Arsenal, Jefferson County, Arkansas, Henry W. Robison

Journal of the Arkansas Academy of Science

A survey of the fishes of the Pine Bluff Arsenal (PBA) located in Jefferson County, Arkansas was initiated in February 1999 and continued until October 1999 with several supplemental collections made in 2000. A total of 3,396 fishes was taken in 81 collections on the PBA and revealed 59 species distributed in 17 families and 36 genera. The most abundant fishes collected were Dorosoma petenense, Gambusia affinis, Labidesthes sicculus, Notemigonus crysoleucas, and Lepomis marginatus.

United States Geological Survey: Staff Publications

While conducting field work in Morton County, southwestern Kansas and Baca County, southeastern Colorado, during the period 27 May to 2 July 1997, we found 36 nests of seven bird species. Nests were not searched for systematically, but were found coincidentally as data were collected along transects during research investigating the breeding bird and plant communities of black-tailed prairie dog (Cynomys ludovicianus) colonies and noncolonized shortgrass prairie (Winter 1999).

Allometry, Sexual Size Dimorphism, And Niche Partitioning In The Mediterranean Gecko (Hemidactylus Turcicus), James B. Johnson, Lance D. Mcbrayer, Daniel Saenz

Faculty Publications

Hemidactylus tucrius is a small gekkonid lizard native to the Middle East and Asia that is known to exhibit sexual dimorphism in head size. Several potential explanations exist for the evolution and maintenance of sexual dimorphism in lizards. We tested 2 of these competing hypotheses concerning diet partitioning and differential growth. We found no differences in Average meal size (volume) or in any single dimension of prey size for similarly sized males and females. allometric patterns of increases in head size also were measured in males and females. We found that males exhibited a mixture of isometric and positively allometric …

Utah Wolf Management Plan, Utah Division Of Wildlife Resources Publication #: 05-17, The Utah Division Of Wildlife Resources, The Utah Wolf Working Group

All U.S. Government Documents (Utah Regional Depository)

This plan will guide management of wolves in Utah during an interim period from delisting until 2015, or until it is determined that wolves have established1 in Utah, or assumptions of the plan (political, social, biological, or legal) change. During this interim period, arriving wolves will be studied to determine where they are most likely to settle without conflict.

The goal of this plan is to manage, study, and conserve wolves moving into Utah while avoiding conflicts with the wildlife management objectives of the Ute Indian Tribe; preventing livestock depredation; and protecting the investment made in wildlife in Utah.

Analysis Of Genotypic And Phenotypic Differences In Desmognathus Quadramaculatus Across The Southern Appalachians, Deborah Susan Merritt

Theses, Dissertations and Capstones

Populations of Desmognathus quadramaculatus were compared for genotypic and phenotypic differences across 5 states in the Southern Appalachians. Series consisting of 10 salamanders each were collected from West Virginia, Virginia, Tennessee, North Carolina and Georgia. Salamanders were assessed for genotypic differences by using allozyme (proteins with polymorphic loci) electrophoresis staining for 13 loci of the muscle, liver and stomach tissue. Nei’s genetic distance was used to score genetic variation between populations. Phenotypic differences were assessed by comparing 10 external morphological measurements between populations. Mahalanobis’ distance was used to score morphological differences between populations. Both genetic and morphological differences were correlated …

Under the auspices of the Dakota Water Resources Act (DWRA) of 2000, the Secretary of the Interior has been directed to conduct a comprehensive study of the water quality and quantity needs of the Red River Valley and the options for meeting those needs. As such, the Bureau of Reclamation (Reclamation) requested technical support from the U.S. Geological Survey (USGS) Columbia Environmental Research Center (CERC) for an evaluation of the risks and economic consequences of biota transfers potentially associated with interbasin water transfers that might occur between the Upper Missouri River and the Red River of the North (Red River) …

Access And Allocation Arrangements For The Commercial 'Wetline' Fisheries. Proposals For Discussion., Commercial Access Panel

Fisheries Management Papers

The Minister for Fisheries established this review of open access (wetline) commercial fishery arrangements to provide a more effective management framework for wetline fishing and to complement the recreational initiatives. This must involve the removal of excess fishing capacity, including latent effort, from the fishery and the establishment of a dedicated commercial fishery with clear entry criteria and an appropriate limit on catch in each bioregion. However it must be made clear that the ‘wetline review’ is not a sectoral resource sharing exercise. Following the implementation of new management arrangements for the ‘wetline’ fisheries, the appropriateness of the existing levels …
