Nutrient Balance On Nebraska Feedlots, Richard K. Koelsch, Gary Lesoing

Nebraska Beef Cattle Reports

A balance between the nutrient inputs and the managed nutrient outputs balance was constructed for 16 Nebraska feedlots to provide insight to potential environmental risks. Substantial nitrogen and phosphorus imbalances were observed for many participating feedlots. Size of the livestock operation and the degree of integration of livestock with a cropping operations provided only limited explanation concerning nutrient balance variations observed among the feedlots. Substantially improved nutrient balances were achieved by those feedlots marketing manure nutrients to off-farm customers. A “sustainable” nutrient balance appears possible for larger feedlots actively marketing manure nutrients.

In Situ Method For Estimating Forage Protein Degradability, Ryan Mass, Greg Lardy, Rick Grant, Terry J. Klopfenstein

Nebraska Beef Cattle Reports

Four experiments including vegetative and dormant forages tested modifications of the in situ neutral detergent fiber nitrogen (NDFN) method of estimating forage undegraded intake protein (UIP). Experiments 1, 2 and 3 tested bag size, closure, rinsing, density, and reflux conditions. None of the modifications affected in situ NDFN content. Experiment 4 compared rates of in situ NDFN digestion calculated with or without correction for undegradability. A close relationship exists between rates calculated by the two methods. Modifications make the improved in situ NDFN method a more desirable means of estimating forage UIP than the standard method.

Wood Frog (Rana Sylvatica) Use Of Wildlife Ponds In Northcentral Arkansas, Michael E. Cartwright, Stanley E. Trauth, J. D. Wilhide

Journal of the Arkansas Academy of Science

Forty-one wildlife ponds were monitored between 1988 and 1992 for breeding use by wood frogs (Rana sylvatica). Data were collected on egg deposition and pond characteristics. Breeding activity and characteristics were similar to that reported in other portions of the range of the wood frog. We also monitored 15 newly-constructed ponds to determine chronological breeding patterns. Data collected for each site indicated a significant increase (P< 0.05) in the number of egg masses deposited in ponds as they age from 1-3 years during our study period. Increased chronological use of newly-constructed ponds may be due to localized population increase resulting from greater availability of breeding habitat

In-Stream Monitoring Of Sediments And Water In The Lower Ouachita River For Site Impact To Aquatic Biota, Jerry L. Farris, J. T. Knight, C. D. Milam, F. Buzen, J. F. Nix

Journal of the Arkansas Academy of Science

Reported reduced sportfish densities in the main channel of the Ouachita River prompted an investigation, beginning in 1990, into potential causes of ongoing impairment to aquatic biota. In-stream monitoring that incorporated toxicity testing of sediments and water was conducted to discern potential sources of contaminants that might be related to the suboptimal fishery populations. Organisms selected to evaluate chronic impairment included larval fish, clams, midges and water fleas. The fathead minnow {Pimephales promelas) and cladoceran (Ceriodaphnia dubid) were used to estimate patterns of toxicity associated with water from seven designated reaches and selected tributaries of the Ouachita River. Larval survival …

Telemetric Observations Of Foraging Ozark Big-Eared Bats In Arkansas, J. D. Wilhide, V. Rick Mcdaniel, Michael J. Harvey, Daniel R. White

Journal of the Arkansas Academy of Science

Ozark big-eared bat (Corynorhinus townsendii ingens) foraging activities were studied during 1995 in Marion County, Arkansas. Adult bats were equipped with radiotransmitters and tracked during June and July. Foraging activities were generally within 1 kilometer (km) of the roost cave. Male bats ranged farther than females with the exception of one female that flew 2.5 km into a different watershed. Male big-eared bats and northern long-eared bats (Myotis septentrionalis) were also found within the maternity colony.

Behaviour Of Gilbert's Potoroo (Potorous Gilbertii Gould) In Captivity, Kylie Dijon Burke

Theses : Honours

In late 1994, Gilbert's Potoroo was rediscovered almost 120 years after it was believed to have become extinct. It was found at Two Peoples Bay Nature Reserve, near Albany, Western Australia. Since then, it has become urgent that detailed studies of the potoroo's behaviour and ecology be undertaken, so as to increase the understanding of the needs of 'this critically endangered marsupial. Due to its critical status, increasing the number of animals is of paramount importance to the continued survival of this species. An understanding of the behavioural repertoire of the species will aid in its recovery and provide the …

The Birds And Habitat Of Kings Park, Bradley W. Cox

Theses : Honours

Kings Park is a large urban park in the centre of Perth with extensive areas of semi-natural bushland. The park is an important refuge for birds in the metropolitan area but is losing species through habitat disturbance. Understanding the way in which birds are related to their habitat helps to understand the effect of habitat disturbance on the bird community. The aim of this project was to generate guidelines which will aid in the management and conservation of birds in the park, through an understanding of the relationship of the birds to their habitat. The avifauna and various habitat factors …

A New Subspecies Of Meriones Tristrami Thomas, 1892 (Rodentia:Gerbillinae) From Kilis (Southeastern Turkey):Meriones Tristrami Kilisensis Subsp. N., Nuri Yi̇ği̇t, Ercüment Çolak

Turkish Journal of Zoology

In this study, seventeen specimens of Meriones tristrami from Kilis were compared with the specimens of Meriones tristrami bodenheimeri along with topotypes of Meriones tristrami lycaon close to those from Kilis. It was determined that the specimens from Kilis were distinguishable from M.t. lycaon by characters such as dorsal coloration, Tx100 / HB (ratio of tail length to head and body), zygomatic breadth, occipitonasal length, basal length, diastema length, occipital width, weight, baculum shape and fundamental number of chromosomes. Thus, the specimens of M. tristrami from Kilis were determined to be a new subspecies, Meriones tristrami kilisensis subps. n.

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The parasite fauna in cetaceans from Puerto Rico, the Virgin Islands, and the larger Caribbean region is poorly known. We provide the first records for parasite biodiversity among a diverse assemblage of cetaceans from the Caribbean Sea. Internal and external parasites and commensals were collected from stranded whales and dolphins salvaged in Puerto Rico, the United States and British Virgin Islands, Jamaica, and Venezuela between 1989 and 1997. A total of 47 individuals of 16 species of whales and dolphins (15 odontocetes and one mysticete) were examined. Overall, parasites and commensals were found in 34 (72.3%) animals, representing 13 species …

Locational Factors Determining The Distribution Of Nesting Sites For A Colony Of Wedge-Tailed Shearwaters, Puffinus Pacificus, On West Wallabi Island, Houtman Abrolhos, Western Australia, Julie Davis

Theses : Honours

West Wallabi Island in the Houtman Abrolhos, Western Australia, provides significant breeding habitat for the largest colony of Wedge-tailed Shearwaters, Puffinus pacificus, in the Eastern Indian Ocean. The Department of Conservation and Land Management (CALM) surveyed the Island in 1992 and estimated the population to be in excess of 1,117,000 pairs of breeding birds. Recent proposals to open the Abrolhos area to a larger number of visitors has identified the need for more detailed investigations into the relationship of birds and habitat. An understanding of this relationship provides a means of determining the ways in which populations will respond to …

Supernumerary Teeth In Pleistocene, Recent, And Hybrid Individuals Of The Spermophilus Richardsonii Complex (Sciuridae), H. Thomas Goodwin

Faculty Publications

A supernumerary distal upper molar, always expressed bilaterally, occurred in Pleistocene (one of 204) and Recent (five of 1,667) specimens of the Spermophilus richardsonii complex. Among Recent specimens with the abnormality, three of four with known provenance came from adjacent colonies with hybrids of S. richardsonii (Richardson's ground squirrel) and S. elegans (Wyoming ground squirrel). Elsewhere, the trait was rare in S. richardsonii (one of 947) and absent in S. elegans (out of 668). Affected individuals exhibited normal P3-M2, but two aberrant teeth distal to M2. Aberrant teeth exhibited a mosaic of features typical of M2, M3, and atypical of …

Chondrocranial Anatomy And Skeletogenesis In Dendrobates Auratus, Rafael O. De Sá, Shannon Hill

Biology Faculty Publications

The larval chondrocranium and visceral skeleton of Dendrobates auratus ls described and compared with those of other dendrobatids. Four characters, i.e. lack of fusion between orbital cartilages and otic capsules, wide processus muscularis palatoquadrati, lack of processus pseudopterygoideus, and lack of processus anterolateralis hyalis, represent derived conditions for Dendrobates within Dendrobatidae. Cranial and postcranial ossification sequences are reported for D. auratus and Epipedobates tricolor. Skeletogenesis is earlier in E. tricolor, but the overall pattern of ossification is similar in the two species.

Habitat Selection, Reproductive Success, And Impaling Patterns Of A Migratory Population Of Loggerhead Shrikes, Jeffrey D. Esely Jr.

Masters Theses

I studied habitat selection and reproductive success of a migratory population of Loggerhead Shrikes (Lanius ludovicianus migrans) as well as the temporal and spatial patterns of impaling exhibited by this population during the nesting season. The selection of breeding habitat was investigated at different spatial scales. Thirty-eight (67%) of 57 nests were located in osage orange (Maclura pomifera) trees. Shrike territories (area ≤ 200 m from nest site) contained significantly more pasture, fenceline, and perch sites, but less com, alfalfa, and forest than random sites. At larger spatial scales, more grassland was detected within 300 m …

Turkish Journal of Zoology

In this study, ecology and biology of Microtus guentheriwere investigated based on both field and laboratory observations along with its effects on agricultural crops. It was determined that this vole has a shallow burrow with numerous entrances and does not store food in its burrow. In captivity, M. guentherigave litters from September to June and a female produced 42 pups, being seven litters during a reproduction season. The duration of pregnancy varied 20 to 21 days. The average litter size was 5.5 and young were born in an average weight of 3.3 g. The fur developed at an age of …

Comparative Toxicological Studies Of Rb-A (Neem Extract) And Coopex(Permethrin+Bioallethrin) Against Sitophilus Oryzae With Reference Totheir Effects On Oxygen Consumption And Got, Gpt Activity, Mohammad Arshad Azmi, Syed Naimul Hasan Naqvi, Muhammed Farhanullah Khan, Kahkashan Akhtar, Farah Younus Khan

Turkish Journal of Zoology

The toxicity of a neem extract RB-a in comparison with a pyrethroid, Coopex, was studied along with their effects on GPT and GOT activities and oxygen consumption in S. oryzae. The LD 50 value of Coopex was found to be 6.128 \mug/cm 2 whereas RB-a was found not to be an acute contact poison. Even at a dose of 1257 \mug/cm 2 it could cause 34% mortality of S. oryzae. The oxygen consumption under the effects of Coopex was found to decline less i.e. at 6.12 \mug/cm 2 from 0.0005191 to 0.0006589, as compared to RB-a where the rate of …

A Comparison Of Predation Rates On Real And Artificial Nests Of Grassland Birds, William B. Davison

Masters Theses

I compared rates of predation between real and artificial nests of grassland birds in order to test the impact of nest type, nest position, and egg size on predation rates. I distributed wicker avicultural baskets and realistic grass nests baited with a clay egg and either northern bobwhite (Colinus virginianus) or house sparrow (Passer domesticus) eggs in four Conservation Reserve Program (CRP) grasslands in east-central Illinois. Nest success averaged 86.5% for 12 days of exposure for artificial nests. For real nests, nest success was markedly lower; averaging 39% over the entire nesting cycle and 59% during approximately 12 days of …

Heartworm And Lungworms In Illinois' Canids And Their Possible Effect On Coyote Condition And Reproduction, David G. Gregory

Masters Theses

This study focuses on the prevalence of heartworm and lungworms in Illinois' canid species, and the effect that they may have on condition (body weight, kidney fat, marrow fat) and reproduction (placental scars) on coyote populations. A total of 1,150 coyotes (Canis latrans), 2,269 domestic dogs, 47 red foxes (Vulpes vulpes), and 2 gray foxes (Urocyon cinereoargenteus) were examined. Prevalence of heartworms (Dirofilaria immitis) averaged 17.8% in coyotes, 3.0% in domestic dogs, 2.0% in red foxes, and 0% in gray foxes. Domestic dogs not receiving any type of prophylactic treatment had a higher prevalence (12.5%) of heartworms than dogs on …

Selecting Linear-Score Distributions For Modeling Milk-Culture Results, H. G. Allore, David J. Wilson, H. N. Erb, P. A. Oltenacu

Animal, Dairy, and Veterinary Science Faculty Publications

The data for this cross-sectional retrospective study are from surveys of 65 dairy-cattle herds in central New York, USA sampled between February, 1993 and March, 1995. The objective was to identify probability distributions of logarithmically transformed somatic-cell counts (linear score) for use in a simulation model of mastitis and milk quality. Probability density functions were estimated using maximum-likelihood estimators for the linear score of individual-cow composite milk samples culture negative and culture positive for the pathogens Streptococcus agalactiae, Streptococcus non-agalactiae, Staphylococcus aureus, and coagulase-negative staphylococci for the complete dataset and by bulk-tank somatic-cell count group (< 500 000, ≥ 500 000 SCC/ml). Based on the rankings of three goodness-of-fit tests (Anderson-Darling, Kolmogorov-Smirnov and x^{2 …}

Dispersal Patterns Of Subadult And Adult Colorado Squawfish In The Upper Colorado River, D. B. Osmundson, Ronald J. Ryel, M. E. Tucker, D. B. Burdick, W. R. Elmblad, T. E. Chart

Wildland Resources Faculty Publications

Abstract.—We investigated distribution and dispersal patterns of subadult and adult Colorado squawfish Ptychocheilus lucius (recently renamed the Colorado pikeminnow) throughout their range in the upper Colorado River. Annual, river-wide, capture–recapture data were used to document movements during a 5-year period (1991–1995). Average total length of Colorado squawfish progressively increased upstream: juveniles and subadults occurred almost exclusively in the lowermost 105 km of the 298-km study area, whereas most adults were concentrated in the uppermost 98 km. This was most pronounced early in the study and less so later due to the effect of two or three strong year-classes that dispersed …

Ecology Of The Eastern Cottonmouth (Agkistrodon P. Piscivorus) At Back Bay National Wildlife Refuge: A Comparative Study Of Natural And Anthropogenic Marsh Habitats, Chad Lee Cross

Biological Sciences Theses & Dissertations

Mark-recapture sampling and radiotelemetry were used to investigate populations of the eastern cottonmouth, Agkistrodon p. piscivorus, in both natural and anthropogenic marsh habitats at Back Bay National Wildlife Refuge (BBNWR), Virginia Beach, Virginia from autumn 1995 to late spring 1998. Mark-recapture subjects were captured, marked by ventral scale-clipping, and released back into the population. A modified Schnabel Census estimator was used to estimate population sizes and corresponding densities in both marsh systems based on a total of 244 captures of 222 individuals. Most snakes were found >0.05 in from water, but it was apparent that proximity to water played …

Beef Quality Assurance–Past, Present, Future, Gary C. Smith, J. D. Tatum, K. E. Belk

Range Beef Cow Symposium

The Beef Quality Assurance Task Force (BQATF) was formed in early 1986 when three NCBA (then, the National Cattlemen's Association) Policy Committees independently directed NCBA to address "the growing issue of consumer concern about the safety and wholesomeness of beef." It was believed that the cattle industry's efforts aimed at improving beefs image as a healthful food with regard to its nutrient profile could not stand alone, and that lingering consumer concerns about drug and chemical residues in beef could negate any progress made in the diet/health area. Consequently, the BQATF (then, the Beef Safety Assurance Task Force) was formed …
