Avian Communities Of Large Reclaimed Mine Grasslands In Southwestern Indiana, Travis L. Devault

All-Inclusive List of Electronic Theses and Dissertations

Many bird species native to the tallgrnss prairie region oCthc central U.S. have declined drastically since European settlement due lo the destruction and alteration of grassland habitat. In this study, the breeding bird communities or 21 large reclaimed surface coal mine grasslands in a seven-county area or southwestern Indiana were examined with respect to species and guild composition, density, variation among sites, and grassland size. In addition, the vegetation characteristics of nine large mine grasslands were described and related to the presence and abundance or eight grasslund bird species common to the study areas. The immense size of mine grasslands …

Evidence Supporting The Recent Origin And Species Status Of The Timberline Sparrow, John Klicka, Robert M. Zink, Jon C. Barlow, W. Bruce Mcgillivray, Terry J. Doyle

Ornithology Program (HRC)

The Timberline Sparrow (Spizella taverneri), although originally described as a species, is currently classified as a subspecies of the more widespread Brewer's Sparrow (S. breweri). We investigated the taxonomic status and recent evolutionary history of these species by comparison of both morphological and molecular characters. Morphometric comparisons using 6 external and 18 skeletal measurements show that S. taverneri specimens from two widely separated populations (Yukon and southwestern Alberta, Canada) are indistinguishable with respect to size yet are significantly larger (by 3%) than representatives of several breweri populations. Analysis of 1,413 base pairs of mitochondrial DNA (mtDNA) for 10 breweri and …

The Translocation Of Barramundi. A Discussion Paper., Makaira Pty Ltd

Fisheries Management Papers

There is recognisable economic benefit to the translocation of barramundi, but there is also a need to ensure the translocation will not adversely impact upon the genetic diversity, introduce disease or impact on the natural environment and biodiversity. This discussion paper has been prepared to provide information to assist in the assessment of the possible impact of translocation of barramundi into and within Western Australia, for the purposed of recreational stock enhancement, aquaculture development and domestic stocking. In contemplating the translocation any aquatic species, signigicant economic and social benefits must be balanced with biological and environmental risks; that is, the …

Fisheries Research Report No. 111 - Sea Temperature Variability Off Western Australia 1990 To 1994, Alan Pearce, Mark Rossbach, Marion Tait, Rhys Brown

Fisheries Research Reports

Analysis of temperature data from coastal waters between Shark Bay and Cape Mentelle has shown the main features of temporal and spatial variability in temperature along the Western Australian coastline. Three distinct periods of variability emerge: the annual cycle (peak temperatures generally in January-February and troughs in July-August), a few-day (weatherrelated) cycle, and the diurnal pattern.

Summer temperatures range from 24° C (South Passage) to 19° C (Cape Mentelle), and winter temperatures from 21° C (South Passage) to 16° C (Marmion). Mean annual temperature ranges (winter minimum to summer maximum) are between 3° C (South Passage) and 7° C (Alkimos), …

Estructura Del Condrocráneo Y Esqueleto Visceral De Larvas De Pseudis Minuta (Anura, Pseudidae, E. O. Lavilla, Rafael O. De Sá

Biology Faculty Publications

The chondrocranium and visceral skeleton of Pseudis minuta tadpoles are described, based on a series of five larvae in stages 31 - 35 of Gosner (1960). Among their striking characters are the presence of peculiar articular surfaces between cornua trabeculae and suprarostral cartilage, the incomplete development of the orbital cartilage, the high fenestration of the floor of the cavum cranii, the fusion of posterior foramina, and the fusion of spicules 3 and 4 in the hyobranchial skeleton.

Overcoming Response Bias Using Symbolic Representations Of Number By Chimpanzees (Pan Troglodytes), Sarah T. Boysen, Kimberly L. Mukobi, Gary G. Berntson

Sentience Collection

We previously reported that chimpanzees were unable to optimally select the smaller of two candy arrays in order to receive a larger reward. When Arabic numerals were substituted for the candy arrays, animals who had had prior training with numerical symbols showed an immediate and significant improvement in performance and were able to select reliably the smaller numeric representation in order to obtain a larger reward. Poor performance with candy arrays was interpreted as reflecting a response bias toward the intrinsic incentive and/or perceptual features of the larger array. In contrast, the Arabic numerals represent numerosity symbolically and appear to …

Spring Field Report, March To May 1999, W. Ross Silcock, Joel G. Jorgensen

Nebraska Bird Review

This spring proved an exciting season for several reasons. For warbler fans, it described a dream with lots of birds to look at and a rather incredible species count (for anywhere) of no fewer than 381 Many "eastern" warblers were found westward, especially at "islands" of habitat such as the Geneva Cemetery and similar spots just beyond the western edge of the original eastern woodland region, as well as the Panhandle. For rarity counters, spring included no fewer than 4 first state records: Glossy Ibis, Gray Flycatcher, Black-throated Gray Warbler, and Brambling. We make here a special note that the …

The Timing And Pattern Of Myogenesis In Hymenochirus Boettgeri, Matthew T. Smetanick, Rafael O. De Sá, Gary P. Radice

Biology Faculty Publications

Differences in the relative timing of homologous developmental events among closely related species, known as heterochronies, may provide valuable clues in understanding evolutionary relationships (McKinney, 1988; McNamara, 1995). Examining the timing of myogenic events is a relatively easy and effective method for finding heterochronic events. For example, whether muscle proteins and myofibrils appear before or after multinucleation can be determined through histological techniciques (Kielbowna, 1981). Simple observations of live specimens can pinpoint functional landmarks such as first twitch (spontaneous or due to external stimuli) and first heartbeat.

Expression And Action Of Transforming Growth Factor Beta (Tgfβ1, Tgfβ2, And Tgfβ3) During Embryonic Rat Testis Development, Andrea S. Cupp, Grace Kim, Michael K. Skinner

Department of Animal Science: Faculty Publications

The objective of the current study was to determine the role of transforming growth factor beta (TGFβ) during seminiferous cord formation and embryonic testis development. The expression pattern of mRNA for TGFβ isoforms was evaluated during testis development through a quantitative reverse transcription polymerase chain reaction (QRT-PCR) procedure. Expression of mRNA for TGFβ1 was highest at postnatal day 0 (P0) and P10. In contrast, TGFβ2 was high at embryonic day 15 (E15), declined at E16, and showed a transient increase at P0 through P3 of testis development. Interestingly, expression of mRNA for TGFβ3 was high during embryonic development and then …

Ecology Of The Malay Civet (Viverra Tangalunga) In A Logged And An Unlogged Forest In Sabah, East Malaysia, Christina P. Colon

Publications and Research

Malay civets in a dipterocarp rain forest were studied from December, 1995, through June, 1997, in the Ulu Segama Forest Reserve in Sabah, East Malaysia. To investigate the basic ecology of this species and explore the potential impact of selective logging, data on home range, activity and diet were collected on study animals in an unlogged and a selectively logged forest, and comparisons made.

Density in the unlogged forest was 1/0.46 km² , and 1/1.07 km² in the logged forest. Mean home range size based on a 95% minimum convex polygon was 110 ha. and did not differ …

Analysis Of Intraguild Predation With A Consideration Of Adaptive Foraging, Toshinori Okuyama

School of Biological Sciences: Dissertations, Theses, and Student Research

Identification of interactive units in food webs is particularly important in population and community ecology. Intraguild predation has gained much attention recently with the recognition of its prevalence in the field, although its significance has not been fully studied. Nature contains much more complex interactions than a simple food chain. Yet, much theory still focuses on the trophic levels connected in a single linear chain. In this thesis, I study intraguild predation including the consideration of animal behavior whose importance is also often neglected in population and community ecology.

First, the concepts of intraguild predation and animal behavior are introduced. …

The Ecology And Life History Of The Mexican Tetra, Astyanax Mexicanus, (Teleostei: Characidae) In The Lower Rio Grande Valley, Texas, Mario Estrada

Theses and Dissertations - UTB/UTPA

The Mexican tetra has been found to migrate from shallow waters in the spring and summer months into deeper waters during the winter months when temperatures are too cold for their survival. This fish is omnivorous with insect material being the major source of food. Its food types include green algae, nematoceran larvae, hemipterans, coleopterans, hymenopterans, dipterans, ostracods, fish eggs and amphipods. Furthermore, size classes showed that the Mexican tetras reached their largest size at the River site and smaller sizes at the Bridge and Gate sites and apparently breed year round. They are capable of producing from 300 to …

Nest Success Of Dabbling Ducks In A Human-Modified Prairie: Effects Of Predation And Habitat Variables At Different Spatial Scales, Jaime E. Jimenez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nest success of dabbling ducks in the Prairie Pothole region of North America has been declining for the past 40 years in parallel with declines in duck populations. Low nest success seems to result from the combination of an extremely fragmented breeding ground in a human-dominated landscape with an abundant and expanding community of generalist nest predators. Studies that examined variables associated with nest vulnerability to predation have produced contradictory results, likely because of simplistic approaches, lack of spatio-temporal replication, use of artificial nests, and the effect of confounding variables. I attempted to clarify the equivocal findings of previous studies …

A Social Analysis Of Grazing Management On National Forest Lands: A Case Study In Catron County, New Mexico, Alexis S. Watts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The rural west in this country faces increased national pressure concerning the management of natural resources on public lands. Issues regarding natural resource management are becoming more important as they continue to affect rural communities and capture the attention of a variety of interest groups. Natural resource managers are increasingly required to consider social dimensions of resource use and management. Lack of consideration in these areas can lead to dissatisfied, and even hostile, local residents and interest groups. Often land managers face criticism from many groups at once as a result of management decisions.

This study analyzed a particular resource …

Influence Of Type Of Supplemental Carbohydrate On Ruminal Responses And Methane Output From Ruminants Consuming Low-Quality Forage, Raul J. Lira

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In a completely randomized design with a factorial arrangement, three energy supplements and two species (cows and ewes) were evaluated in two identical experimental periods: gestation and lactation. The three supplement treatments were a control, barley, and sugar beet pulp (SBP). The basal diet was tall wheatgrass straw (5.52% CP).

Forage and total dry matter intake (FDMI and TDMI, respectively) interacted (P=.04) with species, supplements, and physiological stages.

An interaction of physiological stage and sampling time occurred for pH. Supplement and sampling time interacted for butyric acid proportion and total VFA concentration.

Diet digestibility displayed an interaction between …

This Cat's Meow: Individual Variation Among Domestic Cats In Maternal Response To An Unrelated Kitten, Theressa Joanne Silver

Dissertations and Theses

Non-offspring nursing and adoption are puzzling behaviors seen in a number of mammalian species (Riedman, 1982; Packer et al., 1992). Although domestic cats show a proclivity for adopting strange kittens, there is a great deal of individual variation in the behavior. The goal of this project was to determine the feasibility of using behavioral observations and other measures of a mother cat's personality to predict her reaction to a strange kitten. Twelve female domestic cats with litters of kittens were tested. Three behavioral tests were done with each cat: New Person Test (NPT), Familiar Person Test (FPT), and Novel Box …

Action Of Retinoids On Embryonic And Early Postnatal Testis Development, Andrea S. Cupp, Jannette M. Dufour, Grace Kim, Michael K. Skinner, Kwan Hee Kim

Department of Animal Science: Faculty Publications

The current study investigates the hypothesis that retinoids have a role in embryonic testis development. The action of retinoids on testis development and the expression of retinoic acid receptors (RARα, RARβ, RARγ) were examined. In embryonic day 13 (E13; plug date 5 E0) testis organ cultures an RAR-selective agonist and alltrans retinoic acid completely inhibited seminiferous cord formation. In contrast, an RARα-selective antagonist had no effect. RT-PCR demonstrated that RARα messenger RNA (mRNA) was expressed at all developmental time points evaluated, which included embryonic day 14 (E14) through postnatal day 30 (P30). Expression of RARβ mRNA was present at E15 …

Observations And Possible Function Of The Striking Anterior Coloration Pattern Of Galathea Intermedia (Crustacea: Decapoda: Anomura), J. M. Hall-Spencer, P. G. Moore, L. U. Sneddon

Veterinary Science and Medicine Collection

Galathea intermedia is common, but cryptic, on Clyde maerl deposits where it lives in small groups of mixed sex and age, sharing shelters (typically dead Dosinia shells) to avoid predation. Its appearance is marked by six iridescent blue spots which may play an important role in intra- or interspecific interactions.

Implications Of Cloning For Breed Improvement Strategies: Are Traditional Methods Of Animal Improvement Obsolete?, L. Dale Van Vleck

Department of Animal Science: Faculty Publications

Can the optimum animal be defined? Will that definition change over time, by location, by market demand? First, assume what may be impossible, that the perfect animal can be defined or that only a limited number of definitions of “perfect” are needed. Then, can the “perfect” animal to match a definition be found? Suppose such an animal is found. Then the question to be answered before trying to clone as a method of genetic improvement becomes “Is the animal perfect because of phenotype or genotype?” In other words, the P = G + E problem exists, which requires traditional methods …
