Insects Inhabiting The Burrows Of The Ozark Pocket Gopher In Arkansas, Peter W. Kovarik, Stephen W. Chordas Iii, H. Robison, P. Skelley, M. Connior, J. Fiene, G. Heidt

Journal of the Arkansas Academy of Science

Pocket gopher burrows provide a stable environment for a variety of inquilines; hence this mammal is regarded as a keystone species. Most of the arthropods inhabiting pocket gopher burrows are restricted to this microhabitat. As part of a planned state-wide biotic survey of insects inhabiting this unusual microhabitat, we have focused our initial sampling efforts on the Ozark pocket gopher (Geomys bursarius ozarkensis; Geomyidae). In 2004 and 2005, pitfall traps were established in pocket gopher burrows and in 2007 and 2008, nests and associated chambers were excavated. Retrieved samples contained scarab, histerid, and rove beetles, cave crickets and anthomyiid flies. …

Maternal Corticosterone Influences On Fear Responses In Offspring Of Quail Divergent Stress Response Lines, Kyndal A. Davis

LSU Master's Theses

Increased fearfulness has been associated with adrenocortical activation. Maternal corticosterone (B) treatment increases egg yolk B, and elevated B in ovo enhances chick avoidance of humans. Quail selected for exaggerated (high stress, HS) as opposed to reduced (low stress, LS) plasma B response to stress are more fearful, and more B is found in the egg yolks of HS than LS hens. Therefore, the underlying fearfulness (tonic immobility, TI) and timidity (hole-in-the-wall box, HWB, emergence) responses were assessed in chicks hatched from eggs of LS and HS hens implanted with silastic tubes containing no B (CON) or B (B-IMPLANT) during …

The Influence Of Calf Selenium Status On Gpx-1 And 3 Activity And Liver Gpx-1 Mrna, Genevieve Elizabeth Tanner

LSU Master's Theses

The purpose of this research was to determine the influence of dietary Se on glutathione peroxidase (GPx)-1 and 3 activities and relative liver GPx mRNA levels in growing Holstein bull calves. Calves (n = 14) were started 28 d after birth on either a Se adequate (0.15 ppm Se) or deficient (0.01 ppm Se) diet consisting of 3 growth phases and maintained on the diet until 180 d of age. Blood samples were taken from each calf for determination of GPx-1 and GPx-3 activity. Three calves were euthanized at d 21 of age for determination of baseline liver GPx-1 mRNA …

Forty-eight calves (heifers n=20, bulls n=28) were randomly assigned one of four dietary treatments which included no additive (C); the yeast culture Saccharomyces cerevisiae (YC); the probiotics Bacillus lichenformis and Bacillus subtilis (P); and both yeast culture and probiotics (YCP). Calves were administered treatments from day 2 to 56 in starter and from day 57 to 84 in grower diets. Body weights were measured at birth and weekly thereafter until day 112 of age. Wither and hip heights were measured weekly. Feed intake, water intake, and fecal scores were recorded twice daily until day 56. Rumen fluid was collected on …

Hatchability Of Post-Peak Egg Production Broiler Breeder Eggs As Influenced By Pre-Incubation Warming, Cameron Benjamin Wiggins Ii

LSU Master's Theses

This research was conducted to determine the effects of pre-incubation warming on the hatchability of post-peak egg production broiler breeder eggs. An experiment with six trials was conducted with 7,920 freshly laid eggs from Ross 308 and 708 broiler breeders from 61-67-wks of age. For each trial, 1,320 eggs were used to determine if pre-incubation warming treatments of 0, 2, 4, and 6, or 0, 3, 6, and 9, or 0, 9, 12 and 15 hrs (at 37.6°C) could improve the hatchability of eggs stored (at 15.5°C) for three days. After a storage period of three days, the eggs were …

The Effect Of Calosoma Sycophanta L. (Coleoptera: Carabidae) Feeding On The Pine Processionary Moth, Thaumetopoea Pityocampa (Denis & Schiffermüller) (Lepidoptera: Thaumetopoeidae), In The Laboratory, Mehmet Kanat, Torul Mol

Turkish Journal of Zoology

We determined the feeding capacity of Calosoma sycophanta L. (Coleoptera: Carabidae) by feeding them the pine processionary moth (PPM), Thaumetopoea pityocampa (Denis & Schiffermüller) (Lepidoptera: Thaumetopoeidae), under laboratory conditions. C. sycophanta is one of the most important predators of PPM larvae and pupae. Adult C. sycophanta can consume as much as 7-8 times their weight in food per day. On average, each C. sycophanta adult injured 10 PPM larvae while consuming 7 of these prey per day. The adults lived for 3-4 years. When young C. sycophanta larvae feed on 1 PPM larva, they can reach 1.4-1.6 cm in length …

The Biology, Nymphal Stages, And Life Habits Of The Endemic Sand Dune Cricket Schizodactylus Inexpectatus (Werner, 1901) (Orthoptera: Schizodactylidae), Gökhan Aydin, Andrey Khomutov

Turkish Journal of Zoology

The biology, nymphal stages, and life habits of the endemic dune cricket Schizodactylus inexpectatus (Werner, 1901) (Orthoptera: Schizodactylidae) were investigated in this study carried out between 2000 and 2007 in the Çukurova delta (Adana province) and in Alata (Mersin province), Turkey. The study showed that S. inexpectatus, which is a nocturnal insect, passes through 9 nymphal stages, each characterised by its own body size. The present study showed that certain properties of burrows, such as their depths, do not depend on either adult or immature stages of the insect. Food preferences of cannibalistic species of S. inexpectatus were also investigated …

Out Of South America: Multiple Origins Of Non-Native Apple Snails In Asia, Kenneth Hayes

Department of Biology Faculty Publications

Apple snails (Ampullariidae: Pomacea) native to the New World have become agricultural and environmental pests widely in southern and eastern Asia since their introduction in about 1980. Although their impacts have been extensively documented, considerable confusion persists regarding their identities and geographical origins. Efforts to resolve the confusion have suffered from inadequate taxonomic and geographical sampling from both native and introduced ranges. Using phylogenetic and genealogical methods, we analysed 610–655 bp of cytochrome c oxidase subunit I DNA sequences from 783 apple snails from 164 Asian locations and 57 native South American locations. In Asia, we found four species of …

Chemical And Sensory Properties Of Beef Of Known Source And Finished On Wet Distillers Grains Diets Containing Varying Types And Levels Of Roughage, B. E. Jenschke, Joshua R. Benton, Chris R. Calkins, Timothy P. Carr, Kent M. Eskridge, Terry Klopfenstein, Galen E. Erickson

Department of Animal Science: Faculty Publications

Beef knuckles (n = 160) were obtained from source-verified cattle finished on 30% wet distillers grains plus solubles enriched with varying levels of alfalfa hay (4 or 8%), corn silage (6 or 12%), or corn stalks (3 or 6%) based on NDF. Proximate analysis, pH, oxidation-reduction potential, fatty acid composition, and sensory analysis were conducted on the rectus femoris muscle to determine if roughage inclusion, in conjunction with wet distillers grains plus solubles and cattle source, affects beef flavor with particular interest in liver-like off-flavor. Proximate analysis, fat content, and oxidation-reduction potential were unaffected (P ≥ 0.129) by diet or …

Distributions And Associations Of Single Nucleotide Polymorphisms In The Leptin Gene Of Bos Taurus And Bos Indicus Cattle, Douglas Henry Fischer, Jr

LSU Master's Theses

In recent years, the use of genetic markers has become more and more prevalent in beef breeding programs. This research focused on four previously identified single nucleotide polymorphisms in a leptin gene on chromosome 4 of beef cows. The SNP were E2FB, T945M, UA1, and UA2. Beef cows used in this research were maintained at the Louisiana State University AgCenter Central Research Station. Cows consisted of purebred Bos tauras and Bos indicus cattle as well as crossbreds. The objectives were to estimate genotypic and allelic frequencies for each SNP and to determine the influence of cow breed type, cow age, …

Influences Of Maternal Corticosterone On Incubation Length And Hatchability Of Eggs Laid By Quail Hens Selected For Divergent Adrenocortical Stress Responsiveness, Jason Berante' Schmidt

LSU Master's Theses

Unstressed and stressed quail hens selected for exaggerated (HS, high stress) rather than reduced (LS, low stress) plasma corticosterone (B) response to brief restraint deposit more B into their eggs than do their LS hen counterparts. HS hens implanted with B also show reduced egg lay when compared to LS- and HS-control and LS-B-implanted hens. Herein, the effects of stress line on length of egg incubation (LEI) and chick body weight at emergence (BWTE) (Exp. 1) and the interactive influences of line with maternal B-treatment (sub-Q control, CON-, or B-implants) on LEI (Exp. 2) and on egg fertility (FERT), total …

Ecological Factors Determining Nesting Habitat For American Avocets, Landon R. Jones

Student Works

The American Avocet (Recurvirostra americana) is a large shorebird that breeds and congregates in open, shallow, saline wetlands (Robinson et al. 1997). Its long, curved bill is well adapted for stirring up and feeding on invertebrates from the benthos. Because they fill such a narrow habitat niche, the majority of avocets concentrate in the thousands to breed in a few hot spots such as Mono Lake in California, and the Great Salt Lake in Utah (Robinson et al. 1997). Avocets arrive at the Great Salt Lake in late March and nest from mid-April to mid-July (Sordahl 1981). They require 15-20 …

The Impact Of Biofuel Production On The Western Australian Livestock Industry, Wim Burggraaf, Anne Wilkins

Bulletins 4000 -

The Western Australian biofuels industry is in its infancy. There is currently only one small commercial biodiesel manufacturer in the State but there have been several announcements of new biofuel projects in 2006 that will be commercialised by 2010. The projected growth of a new biofuels industry in Western Australia (WA), will create greater competition with other industries that rely on grain as an input in their enterprises. Intensive livestock industries such as beef cattle lot feeding, pig rearing, fattening lambs, growing poultry for meat and eggs and feeding dairy cows depend on a consistent supply of high quality whole …

Carnivores, Urban Landscapes, And Longitudinal Studies: A Case History Of Black Bears, Jon P. Beckmann, Carl W. Lackey

Human–Wildlife Interactions

As urban landscapes expand across the globe, it becomes imperative to understand how these landscapes affect large carnivore populations. We examined the effects of humanaltered landscapes on age-specific fecundity and life history parameters for female black bears (Ursus americanus) in urban and wildland regions in the northern Sierra Nevada Mountains of Nevada, including the Lake Tahoe Basin. We followed 12 marked female bears in an urban environment and 10 females in wildland habitats from 1997–2006. Our results show that female bears in urban areas have higher age-specific fecundity rates than did wildland female bears. Despite this difference, female …

Modeling Wildlife Damage To Crops In Northern Indiana, Mónica I. Retamosa, Lee A. Humberg, James C. Beasley, Olin E. Rhodes Jr.

Human–Wildlife Interactions

Comprehensive information on crop damage by wildlife species is critical if effective strategies for controlling wildlife damage are to be formulated. Discriminating how landscape composition and configuration attributes influence crop damage is important for implementing landscape management techniques to resolve human–wildlife conflicts. We analyzed crop damage data from 100 corn fields and 60 soybean fields located in the Upper Wabash River Basin of northern Indiana during 2003 and 2004. We used negative binomial regression to model the rate of damage to corn and soybean crops in response to local and landscape variables. Rate of crop damage was best predicted by …

Evaluation Of An Oral Vaccination Program To Control Raccoon Rabies In A Suburbanized Landscape, Jason R. Boulanger, Laura L. Bigler, Paul D. Curtis, Donald H. Lein, Arthur J. Lembo Jr.

Human–Wildlife Interactions

We evaluated the efficacy of an oral rabies vaccination (ORV) program conducted in Erie County, New York, from July through September, 2002–2005. Ingress of the raccoon (Procyon lotor) rabies variant first occurred along the southern border of Erie County, New York, during 1992 and began to spread northward at a velocity of 31 km/year. Fixed-wing aircraft dropped ORV baits in rural landscapes; helicopters, hand baiting, and bait stations distributed baits in suburban landscapes (x̄ bait densities ranged 59–118 baits/km²). Our study objectives were to quantify rabies case densities, evaluate efficacy of intervention efforts, and determine biological, …

Simultaneous Incubation By Two Females And Nestling Provisioning By Four Adults At A Savannah Sparrow Nest, Nathan J. Zalik, Noah G. Perlut

Environmental Studies Faculty Publications

We present the first observations of misdirected parental care by Savannah Sparrows (Passerculus sandwichensis) including a rare occurrence of simultaneous incubation. Two females simultaneously incubated eggs, brooded, and fed nestlings, and two males fed nestlings in one nest. These behaviors may have been prompted by strong parental instincts in combination with a stressful breeding environment mediated by hayfield management, as any genetic benefits were unlikely.

Trans Fatty Acids Provide Evidence Of Anthropogenic Feeding By Black Bears, Gregory W. Thiemann, Randal S. Stahl, Sharon Baruch-Mordo, Stewart W. Breck

Human–Wildlife Interactions

Bears (Ursus spp.) that become conditioned to anthropogenic food sources pose a risk to human safety and generally need to be relocated, rehabilitated, or destroyed. Identifying food-conditioned bears may be difficult if the animal is not captured or killed while immediately engaged in the nuisance behavior. Fatty acid signature analysis has been used to examine the dietary habits of bears and other carnivores and is based on the predictable incorporation of ingested fatty acids into the consumer’s fat stores. Unusual fatty acids that are available in only a few food types may be particularly useful dietary markers. In this …

Demographic Effects Of Canine Parvovirus On A Free-Ranging Wolf Population Over 30 Years, L. David Mech, Sagar M. Goyal, William J. Paul, Wesley E. Newton

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

We followed the course of canine parvovirus (CPV) antibody prevalence in a subpopulation of wolves (Canis lupus) in northeastern Minnesota from 1973, when antibodies were first detected, through 2004. Annual early pup survival was reduced by 70%, and wolf population change was related to CPV antibody prevalence. In the greater Minnesota population of 3,000 wolves, pup survival was reduced by 40–60%. This reduction limited the Minnesota wolf population rate of increase to about 4% per year compared with increases of 16–58% in other populations. Because it is young wolves that disperse, reduced pup survival may have caused reduced …
