Use Of De‐Oiled Dried Distillers Grains As A Source Of Crude Protein In Finishing Cattle Diets, R.H. Pritchard

South Dakota Beef Report, 2010

A de‐oiled distillers grains (dDGS) product was evaluated as a primary supplemental CP source in finishing diets. The 3 dietary treatments used were: SBM/Urea) as a control, typical of feedlot diets; dDGS) where dDGS replaced all of the SBM and some urea; and dDGS/SBM) where a 90% dDGS/10% SBM (N basis) blend was fed iso‐nitrogenous to the other diets. Eighteen pens of 8 steers each were fed these finishing diets for 132 d. There were no differences in steer performance or carcass traits attributable to diet. The dDGS product can be used effectively to replace oilseed meals and some of …

Wintering Area Dde Source To Migratory White-Faced Ibis Revealed By Satellite Telemetry And Prey Sampling, Michael A. Yates, Mark R. Fuller, Charles J. Henny, William S. Seegar, Jaqueline Garcia

Raptor Research Center Publications and Presentations

Locations of contaminant exposure for nesting migratory species are difficult to fully understand because of possible additional sources encountered during migration or on the wintering grounds. A portion of the migratory white-faced ibis (Plegadis chihi) nesting at Carson Lake, Nevada continues to be exposed to dichloro-diphenyl-dichloroethylene (DDE) with no change, which is unusual, observed in egg concentrations between 1985 and 2000. About 45 to 63% of the earliest nesting segment shows reduced reproductive success correlated with elevated egg concentrations of > 4 µg/g wet weight (ww). Local prey (primarily earthworms) near nests contained little DDE so we tracked the migration and …

Turkish Journal of Zoology

Species of the Ceranisus thrips-attacking genus are difficult to distinguish morphologically. The phylogenetic relationships within the Ceranisus species were explored using nucleotide sequences of the 28S D2 expansion region of the rDNA gene. Bayesian, maximum likelihood, and parsimony inference methods were employed to construct the phylogenetic relationships. Principal component analysis on the Turkish species of Ceranisus, namely antalyacus, menes, bozovaensis, hirsutus, planitianus (a new record for Turkey), pacuvius, and a new species, provided supporting evidence. All known data concerning hosts and geographical distribution are presented. A new species, C. onuri O. Doganlar, sp.n., was described from Turkey.

Management Of Tribolium Castaneum (Herbst) Based On Hue Response, Paul Raj Beautlin Sheribha, Alfred Premjith Jinham, Sathiadas Sam Manohar Das, Kesary Reeba Jasmine

Turkish Journal of Zoology

Possibilities for the management of Tribolium castaneum (Herbst) on stored products using coloured lighting systems was assessed in this study. Adult beetles were exposed in a choice chamber to red, blue, green, and clear tungsten light. T. castaneum adults preferred tungsten, blue, and green lights, and avoided red light. For each colour, beetles were separately reared for 3 generations. Beetles preferred the colour in which they were reared, except for red, which was avoided even by the beetles reared in a red-coloured environment for 3 generations under duress. These beetles moved towards clear tungsten light in a choice chamber. It …

The Effect Of Caloric Restriction On The Population Density Of Freshwater Rotifers (Brachionus Calyciflorus), Ni̇lgün Özdemi̇r, Abdulkadi̇r Çi̇ltaş

Turkish Journal of Zoology

The effects of caloric restriction (CR) on the population density of freshwater rotifers (Brachionus calyciflorus) were investigated in the present study. During experiments with different CRs, groups of rotifers were fed with Chlorella sp. at the same concentrations of 1.5 × 10^6 cells/mL at 12, 24, 36, 48, 60, and 72 h intervals for 20 days. Significant changes were observed both in the population density and the peak days in groups subjected to different CRs (P < 0.01). The highest peak in population density was obtained on the fifth day for rotifers fed in 12 h intervals (269 ± 40.12 individuals/mL, mean ± SD). The rate of population increase (r) varied from 0.608 ± 0.073 to 0.288 ± 0.053, depending on the feeding intervals. The results show that CR affected the population density of B. calyciflorus.

Movement Patterns And Artificial Arboreal Cover Use Of Green Salamanders (Aneides Aeneus) In Kanawha County, West Virginia, Sarah Elizabeth Miloski

Theses, Dissertations and Capstones

Global amphibian declines have spawned a need for amphibian monitoring studies using standardized sampling techniques for early detection of population declines. The Green Salamander (Aneides aeneus) is a declining plethodontid salamander (Family: Plethodontidae) associated with rock outcrops and arboreal habitat. The unique habitat requirements of this species make A. aeneus populations particularly susceptible to habitat perturbations. Although primarily associated with rock outcrops, A. aeneus morphology and ecology suggest that A. aeneus may be highly mobile. High mobility has important implications for habitat management, particularly pertaining to land surrounding rock outcrops. However, few studies have addressed plethodontid movement patterns, which are …

The Natural History & Distribution Of Riverine Turtles In West Virginia, Linh Diem Phu

Theses, Dissertations and Capstones

Turtles are unique evolutionary marvels that evolved from amphibians and developed their protective shelled form more than 200 million years ago. In West Virginia, there are 10 native species of turtles, 9 of which are aquatic. Most of these aquatic turtles feed on carrion and dead plant matter, in the water and essentially "clean" our water systems. Turtles are long-lived animals with sensitive life stages that can serve as both long-term and short-term bioindicators of environmental health. With the increase in commercial trade, habitat fragmentation, degradation, destruction, there has been a marked decline in turtle species. The need for well …

Effect Of Snake Populations On Salamanders As A Result Of Forest Fragmentation, Casey Renee Bradshaw

Theses, Dissertations and Capstones

Forest fragmentation is one of the main causes for the loss of native biodiversity. One consequence is increased proportion of edge habitat that introduces new “edge” species, and makes habitat for interior forest-living species less-suitable. This study was conducted at three sites in Tucker County, West Virginia and included one downhill ski slope, one cross country ski slope, and one gravel road. The main objectives of this study were to determine relative abundance of snake communities, how far species move from edge habitat into the forest and to determine whether snakes are a predatory threat to salamanders, specifically the federally …

Testing The Behavioral Responses Of West Virginia Turtles To Roads And Vehicles, Aaron Clinton Gooley

Theses, Dissertations and Capstones

Road mortality has been identified as a major threat to many turtle species; however, response to passing vehicles, crossing speed, and general behavior while crossing roads has never been investigated in turtles. To investigate these factors, Midland Painted Turtles (Chrysemys picta marginata), Eastern Box Turtles (Terrapene c. carolina), and Stinkpots (Sternotherus odoratus) were collected and placed in a release box on the side of a closed road with an active road running parallel to it 26 m away. Turtles were released via a pulley-operated door facing the road, and their actions videotaped by an …

Long-Term Growth And Monitoring Of The Eastern Hellbender (Cryptobranchus A. Alleganiensis) In Eastern West Virginia, Douglas Charles Horchler

Theses, Dissertations and Capstones

Amphibian declines have been well documented, specifically in the last few decades. The Hellbender, Cryptobranchus alleganiensis, one of North America’s largest salamander species, has suffered dramatic declines throughout much of its range, with estimated declines of up to 77 percent recently documented in some populations. With diurnal and nocturnal searches and mark-recapture techniques, I collected data on the status of Eastern Hellbender populations in Eastern West Virginia. We re-sampled a study site on the West Fork of the Greenbrier River that was first examined in 1998 by Jeff Humphries. Long-term growth and survivorship data were collected and compared to 1998 …
