Breeding Patterns Of Eastern Phoebes In Kansas: Adaptive Strategies Or Physiological Constraint?, Michael T. Murphy

Biology Faculty Publications and Presentations

Data were collected on annual (1980-1983) and seasonal (spring vs. summer) variation in reproduction by the double-brooded Eastern Phoebe (Sayornis phoebe) to test the proposal that phoebes modify reproductive patterns on a seasonal basis and switch from being brood survivalists in spring to brood reductionists in summer. Clutch size did not differ between spring and summer broods nor among years, but spring nests fledged one more nestling than summer nests. In 1981 breeding began earlier, eggs were larger, and nestlings grew faster than in all other years. Clutch size and egg mass within spring clutches increased seasonally. Egg mass was …

Reproductive Biology Of Chesapeake Bay Black Drum, Pogonias Cromis, With An Assessment Of Fixatives And Stains For Histological Examination Of Teleost Ovaries, Brian K. Wells

Biological Sciences Theses & Dissertations

Based on three years of data collection on the periodicity of the spawning run, the gonadosomatic index (GSI), and gonad histology, the spawning season for Chesapeake Bay black drum was found to be significantly shorter and later compared to populations from Florida and the Gulf of Mexico. The GSI is maximal in early April when black drum first enter the Chesapeake Bay region in contrast to data from Florida where GSI peaks during February and March. I confirm that black drum from the Chesapeake Bay are batch spawners. These results match those found for populations of black drum in the …

Cerebral Microcirculatory Effects Of Maturation, Scott R. Elliott

Loma Linda University Electronic Theses, Dissertations & Projects

The present studies demonstrate that in the second (2B) and fourth (4B) branches of newborn and adult sheep middle cerebral arteries, 5-HT2 serotonergic receptors mediate contractile responses to serotonin and that alpha-1 adrenergic receptors mediate contractile responses to norepinephrine. In addition, tissue sensitivity to 5-HT and NE decreases significantly with maturation, but does not vary with branch order. These age-related changes were associated with a decrease in affinity and maximum response in 2B and 4B segments of 5-HT and NE contracted arteries, respectively. Norepinephrine and 5-HT occupancy at the pD₂ rose significantly in 2B segments, but did not change …

The General Adaptation Syndrome In Gerbillus, Bridget L. Moore

McCabe Thesis Collection

The General Adaptation Syndrome or the G.A.S. is the term applied to collective responses to physiological stress. It is initiated by any disturbance in the normal balance of the body functions. These responses affect humans, monkeys, and other animals. The three main physiological changes which occur as a result of stress are enlarged adrenals, shrunken lymphatic organs, and bleeding gastrointestinal ulcers. There are also concomitant changes in the hematocrit and the formed elements of blood. In particular, there is usually a decrease in lymphocytes and eosinophils accompanied by the increase in neutrophils and platelets.

Stress is defined as pressure, or …

How Amaranth Grain Affects Total Body Weight And Major Organ Weight In The Mongolian Gerbil, Rhoshonda Montgomery- Conway

McCabe Thesis Collection

Purpose and Objectives

The purpose of this research is to determine effects of amaranth grain of the body weight and organ weight of the Mongolian gerbil. The literature research indicates that amaranth results in physiological changes that appear to be species-specific rather than general. Since the gerbil is a granivorous animal, it is hypothesized that amaranth will be completely digested and that its nutritional quality will maintain normal to increased growth. While the results of this study cannot be applied to other animals, information has been gained with regard to the influence of amaranth grain on the Mongolian gerbil.

Factors Associated With The Highway Mortality Of Mule Deer At Jordanelle Reservoir, Utah, Laura A. Romin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Highway mortality of deer (Odocoileus sp.) is a nationwide concern. In 1991, 538,000 deer-vehicle collisions occurred nationwide. Property damage to vehicles, human injuries and fatalities, and potential impacts to local deer populations occur from deer-vehicle collisions. Techniques have been evaluated to reduce highway mortality of deer; however, an effective, cost-efficient solution does not exist for widespread use. If mitigative technologies are to be successful, we need to understand deer behavior and movement patterns associated with highway relationships. Most research about highway deer kills has focused on white-tailed deer (Odocoileus virginianus) in mixed hardwood habitat types. The …

Ovarian Follicular Development In Prepubertal Heifers Is Influenced By Level Of Dietary Energy Intake, E. G. M. Bergfeld, F. N. Kojima, Andrea S. Cupp, M. E. Wehrman, K. E. Peters, M. Garcia-Winder, J. E. Kinder

Department of Animal Science: Faculty Publications

Objectives were twofold: 1 ) to determine the chronology of development of dominant ovarian follicles during the peripubertal period in heifers and 2) to determine whether feeding a diet with low energy content that delays onset of puberty alters chronology of dominant ovarian follicular development in peripubertal heifers. Ten heifers of composite breeding ( 1/4 Angus, 1/4 Hereford, 1/4 Red Poll, 1/4 Pinzgauer) were randomly assigned, at 8 mo of age, to receive a diet designed to produce 0.9 (n = 5) or 0.3 (n = 5) kg body weight gain per day for the duration of the experiment. To …

Differential Regulation Of Gonadotropin Synthesis And Release In Ovariectomized Ewes After Treatment With A Luteinizing Hormone-Releasing Hormone Antagonist, T. Sanchez, M. E. Wehrman, G. E. Moss, F. N. Kojima, Andrea S. Cupp, E. G. M. Bergfeld, K. E. Peters, V. Mariscal, H. E. Grotjan Jr., J. E. Kinder, D. L. Hamernik

Department of Animal Science: Faculty Publications

Our working hypothesis was that synthesis and release of LH, but not FSH, were solely dependent on LHRH. Twenty ovariectomized (OVX) ewes were randomly assigned to one of five treatments (n = 4 per group). Ewes were administered a low (10 μg/kg) or high (100 μg/kg) dose of LHRH antagonist (LHRH-Ant) at 24-h intervals for 3 or 6 days. Control ewes received vehicle (5% mannitol) at 24-h intervals for 6 days. Blood samples were collected every 15 min for 4 h before LHRH-Ant or vehicle and every 2 h during the period of treatment to determine concentrations of LH and …

Vocal Learning In Grey Parrots (Psittacus Erithacus): Effects Of Social Interaction, Reference, And Context, Irene M. Pepperberg

Sentience Collection

For many passerines, the extent,timing, and even presence of allospecific vocal learning can be influenced by the form of input that is received. Little data exist, however, on vocal learning in parrots (Psittacidae). I have previously proposed that such vocal learning proceeds most readily when input is (1) referential, (2) contextually applicable, and (3) interactive. The referential aspect demonstrates the meaning of the code to be taught, the contextual aspect demonstrates the use that can be made of the information contained in the code, and the interactive aspect provides explicit training that is constantly adjusted to the level of the …

Luteinizing Hormone Has A Role In Development Of Fully Functional Corpora Lutea (Cl) But Is Not Required To Maintain Cl Function In Heifers, K. E. Peters, E. G.M. Bergfeld, Andrea S. Cupp, F. N. Kojima, V. Mariscal, T. Sanchez, M. E. Wehrman, H. E. Grotjan, D. L. Hamernik, Roger J. Kittok, J. E. Kinder

Department of Animal Science: Faculty Publications

We tested the hypothesis that endogenous pulses of LH have a role in development and maintenance of CL during the estrous cycle of the bovine female. Twenty heifers were synchronized to estrus by treating two times with prostaglandin F_2α 11 days apart (Day 0 = behavioral estrus). Heifers were then randomly assigned to one of four treatments (n = 5/group). Heifers were treated with an antagonist to LHRH (LHRH-Ant; N-Ac-D-Nal[2]¹,4C1-D-Phe² ,D-Pa[3] ³,D-Cit ⁶,D-Ala¹⁰-LHRH; 10 μg/kg body weight) or vehicle (5% mannitol) once every 24 h: 1) LHRH-Ant Days 2-7, 2) LHRH-Ant Days …

Numerical Competence In An African Gray Parrot (Psittacus Erithacus), Irene M. Pepperberg

Sentience Collection

An African gray parrot (Psittacus erithacus), Alex, trained to label vocally collections of 1-6 simultaneously presented homogeneous objects, correctly identified, without further training, quantities of targeted subsets in heterogeneous collections. For each test trial Alex was shown different collections of 4 groups of items that varied in 2 colors and 2 object categories (e.g., blue and red keys and trucks) and was asked to label the number of items uniquely defined by the conjunction of 1 color and 1 object category (e.g., "How many blue key?"). The collections were designed to provide maximal confounds (or distractions) and thus replicate the …

Effects Of Competition And Predation On Prothonotary Warblers And House Wrens Nesting In Eastern Iowa, Timothy Brush

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

In a fragmented midwestern floodplain forest, a small Prothonotary Warbler (Protonotaria citrea) population experienced high competition with House Wrens (Troglodytes aedon) and mammalian nest predation in 1988-89. Despite the provision of 3 types of nest boxes and higher water levels, Prothonotary Warblers did not nest successfully and decreased in the fragmented forest in 1990-91. House Wrens used >90% of the nest boxes in both years. Wren territories doubled within the nestbox area, while remaining constant on an unmanipulated area. In contrast, a larger warbler population had high nesting success during 1990-91 in a relatively unfragmented, wetter forest tract. Such forests, …

Utilization Of Wood Duck Nest Boxes With Respect To Plant Community Type, Orientation And Juxtaposition At The Green Bottom Wildlife Management Area, West Virginia, Anthony Benjamin Borda Jr.

Theses, Dissertations and Capstones

Utilization of wood duck (Aix sponsa, L.) nest boxes was evaluated at the Green Bottom Wildlife Management Area, a 1,110-acre mid-Ohio Valley floodplain. Primary focus was directed upon nest box utilization by the wood duck but use by other wildlife was observed and recorded. Utilization of the nest boxes by the wood duck was analyzed with respect to plant community type, orientation and juxtaposition to other wood duck nest boxes. Forty-three wood duck next boxes were observed and inspected in 1993. Wood ducks nested in 24 of the nest boxes, and 361 eggs were found. Clutch size ranged …

Factors Influencing The Spatial Distribution And Natural History Of Desmognathus Ochrophaeus In West Virginia, Linda D. Ordiway

Theses, Dissertations and Capstones

Desmognathus ochrophaeus, the mountain dusky salamander, is a medium-sized Desmognathine, which inhabits moist woodlands. It is a slender species with a well rounded, slim and tapering tail (Bishop 1967), and 14 costal grooves (Green and Pauley 1987). The average total length is between 70 mm and 100 mm with the tail accounting for approximately half this length (Conant and Collins, 1991). The visual appearance of this salamander is highly variable (figure 1). Most individuals have a distinct light middorsal band with straight edges and darker sides. The colors of the band may vary from yellow, orange, or red to dark …

Out-Of-Season Births Of Elk Calves In Wyoming, Bruce L. Smith

United States Fish and Wildlife Service: Publications

ive out-of-season births of Rocky Mountain elk were documented over a 24-month period at the National Elk Refuge, Wyoming. One of four November neonates was radio-instrumented and subsequently died seven days later due to hypothermia. An April-born calf was killed by a coyote. Supplemental winter feeding of elk at the Refuge may increase the frequency of asynchronous reproduction.

A Contaminants Evaluation Of The Big Blue River In Southeastern Nebraska, Brent J. Esmoil, Kirk D. Schroeder, Timothy E. Fannin

United States Fish and Wildlife Service: Publications

We collected three composite fish and three composite sediment samples from the Big Blue River in southeastern Nebraska to determine the presence of agricultural chemicals or other contaminants. Inorganic analyses consisted of individual analyses for arsenic, selenium, and mercury, as well as an ICP scan for other elements. Organic analyses included organochlorines, polynuclear aromatic hydrocarbons, organophosphate and carbamate pesticides, and chlorphenoxy acid herbicides.

Arsenic was detected in the sediment samples, but not in the fish samples.

Selenium was detected in one of three sediment samples and in all fish samples.

Mercury was not detected in sediment samples, but was detected …

Fisheries Research Report No 101 - The Big Bank Region Of The Limited Entry Fishery For The Western Rock Lobster, Panulirus Cygnus, C F. Chubb, E H. Barker, C J. Dibden

Fisheries Research Reports

The Big Bank region lies to the north of the Abrolhos Islands zone of the limited entry western rock lobster fishery (Zone A) close to the edge of the continental shelf. Since 1986/87 the catches from this previously lightly exploited region have become important to a number of rock lobster fishermen operating in the northern (A and B) zones.

Fishing at Big Bank occurred predominantly in January and February of each season, however, recently introduced regulations have closed the region to fishing until February 10 each year. A maximum of 83 boats have operated in the region catching up to …
