Development Of Endothermy In Nestling Bank Swallows (Riparia Riparia), Richard L. Marsh
Development Of Endothermy In Nestling Bank Swallows (Riparia Riparia), Richard L. Marsh
Richard Marsh
Body temperature (Tb) measurements after exposure to air temperatures (Tₐ) of 20 C or 27 C for 2 h in conjunction with metabolism measurements were used to describe the timing of and basis for developing temperature regulation in nestling swallows. As growth proceeds from hatching to 10 g there is a gradual increase in the Tb after exposure to low Tₐ. As growth continues beyond this point, the ability of nestlings to maintain Tb above Tₐ improves rapidly, such that nestlings weighing over 14 g are completely homeothermic when exposed to 20 C. Conductance (C, in cal [g⋅h⋅°C]⁻¹) decreases throughout …
Effects On Nestling Age And Burrow Depth On Co₂ And O₂ Concentrations In The Burrows Of Bank Swallows (Riparia Riparia), Steven J. Wickler, Richard L. Marsh
Effects On Nestling Age And Burrow Depth On Co₂ And O₂ Concentrations In The Burrows Of Bank Swallows (Riparia Riparia), Steven J. Wickler, Richard L. Marsh
Richard Marsh
Gas samples were taken from the nest chambers of bank swallows (Riparia riparia) and analyzed for CO₂ and O₂ content. The mean CO₂ content was 2.62% with a maximum value of 5.58%, and the mean O₂ content was 17.83% with a minimum value of 14.61%. There was a positive and significant correlation of increasing CO₂ content with both increasing nestling age and increasing total metabolizing mass (adults plus young). With increasing metabolizing mass there is a linear increase in CO₂ content, which suggests no active regulation of gas concentrations. Burrow depth also affected CO₂, particularly in burrows with older nestlings. …
Winter Fattening In The American Goldfinch And The Possible Role Of Temperature In Its Regulation, William R. Dawson, Richard L. Marsh
Winter Fattening In The American Goldfinch And The Possible Role Of Temperature In Its Regulation, William R. Dawson, Richard L. Marsh
Richard Marsh
We investigated whether environmental temperature has any causal role in the winter fattening in certain finches of the subfamily Carduelinae. Correlational analyses between fat content of American goldfinches (Carduelis tristis) and various short- and long-term measures of temperature provide no evidence for a proximate role of this environmental variable in determining the degree of fattening of these birds in southeastern Michigan. Their fat content shows the best correlations (r = −.61 to −.63) with the long-term average minimum temperature or record low temperature for the date of capture. Furthermore, inclusion of long-term thermal measures in multivariate analyses excludes from significance …
Adaptations Of The Gray Catbird Dumetella Carolinensis To Long-Distance Migration: Flight Muscle Hypertrophy Associated With Elevated Body Mass, Richard L. Marsh
Adaptations Of The Gray Catbird Dumetella Carolinensis To Long-Distance Migration: Flight Muscle Hypertrophy Associated With Elevated Body Mass, Richard L. Marsh
Richard Marsh
The size and composition (lean-dry, water, and fat contents) of the flight muscles of the catbird were investigated as a function of the large seasonal changes in body mass which occur in this species. The mass of the pectoralis muscle is highly positively correlated with body mass, leading to an elevation in muscle mass of ∼35% during fall premigratory fattening. The changes in muscle mass are brought about by coordinated variations in all major components of the muscles which were measured. High-oxidative, fast-twitch fibers represent 88% of the total fibers in the pectoralis muscle. The cross-sectional area of the muscle …
The Enzymatic Basis Of High Metabolic Rates In Calling Frogs, Theodore L. Taigen, Kentwood D. Wells, Richard L. Marsh
The Enzymatic Basis Of High Metabolic Rates In Calling Frogs, Theodore L. Taigen, Kentwood D. Wells, Richard L. Marsh
Richard Marsh
Oxygen consumption by male spring peepers (Hyla crucifer) increased linearly with calling rate, reaching peak values of 1.5−1.7 ml O₂/(g⋅h) at the highest calling rates. The intercept of the regression line describing the relationship between metabolism and calling rate does not differ significantly from daytime resting metabolism (0.11 ml O₂/[g⋅h]). Metabolic rate during vigorous locomotor exercise at the same temperature (19 C) was only 1.1 ml O₂/(g⋅h). We measured activities of mitochondrial enzymes in the trunk muscles (internal and external obliques) involved in sound production and in mixed hind limb muscles of male and female frogs. Male trunk muscles were …
Measurement Of Maximum Oxygen Consumption In Guinea Fowl Numida Meleagris Indicates That Birds And Mammals Display A Similar Diversity Of Aerobic Scopes During Running, David J. Ellerby, Maryellen Cleary, Richard L. Marsh, Cindy I. Buchanan
Measurement Of Maximum Oxygen Consumption In Guinea Fowl Numida Meleagris Indicates That Birds And Mammals Display A Similar Diversity Of Aerobic Scopes During Running, David J. Ellerby, Maryellen Cleary, Richard L. Marsh, Cindy I. Buchanan
Richard Marsh
Judgement of exercise performance in birds has been hampered by a paucity of data on maximal aerobic capacity. We measured the maximal rate of oxygen consumption (V̇o₂,max) in running guinea fowl Numida meleagris, a bird that has been used in several previous studies of avian running. Mean V̇o₂,max during level treadmill running was 97.5±3.7 mL O&8322; kg⁻¹ min⁻¹ (mean ± SEM, N=5). V̇o₂,max was on average 6% higher when the birds ran uphill compared with the value during level running (paired t-test, P=0.041, N=5). The mean basal rate of oxygen consumption (V̇o₂,bmr) of the same individuals was 7.9±0.5 mL kg⁻¹ …

Fall Field Report, August–November 2010, W. Ross Silcock
Nebraska Bird Review
This was a pretty routine fall for the most part, although there were scattered early and late dates and high counts as in most seasons. Decidedly non-routine, though, was the appearance of two rarities, Ross's Gull and Brown-headed Nuthatch, both enjoyed by many. A surprising 15 gull species were reported, this without much help from L McConaughy! Also notable were the sea-ducks, scoters, and Long-tailed Duck, which were in good numbers.
Tom Labedz, collections manager at the University of Nebraska State Museum, is an excellent source; he contributed greatly to discussions herein on Greater Prairie-Chicken and Fox Sparrow.

Flank Gland-Secreted Putative Chemosignals Pertaining To Photoperiod, Endocrine States, And Sociosexual Behavior In Golden Hamsters, Ying-Juan Liu, Da-Wei Wang, Lixing Sun, Jin-Hua Zhang, Jian-Xu Zhang
All Faculty Scholarship for the College of the Sciences
Behavioral studies have shown that flank glands are involved in chemical communication in golden hamsters Mesocricetus auratus but little chemical analysis has been conducted on volatiles arising from these glands. Using gas chromatography- mass spectrometry, we detected compounds from the flank glands of males, only eight of which were also produced in females. Based on these chemical data we performed a number of further experiments. By manipulating light we found that males exposed to short-photoperiods developed smaller flank glands than those exposed to long-photoperiods. Six flank gland volatiles reduced in relative abundance, which possibly coded for reproductive status of males …

Nebraska Bird Review
The year 2009 marked the 25th year of existence of the Nebraska Ornithologists' Union Records Committee (NOURC). Its beginning can be traced to one person—Wayne Mollhoff. Wayne raised the need for a records committee in the spring of 1985 at the NOU Annual Meeting in Gretna, Nebraska. At the general membership meeting, then-president Gary Lingle appointed Wayne to form a committee to establish a Nebraska Ornithologists' Union Records Committee. Using procedures from several other states' records committees, Wayne developed a set of operating guidelines or by-laws specific to Nebraska. Further discussion of a records committee continued at the 1985 NOU …

Impacts Of Predation Risk And Development On Susceptibility Of North American Anurans To Ranaviruses, Nathan Alden Haislip
Impacts Of Predation Risk And Development On Susceptibility Of North American Anurans To Ranaviruses, Nathan Alden Haislip
Masters Theses
For over three decades, amphibian populations have been declining across the globe. Emerging infectious diseases are responsible for some of these declines. Ranaviruses have caused die-offs in wild amphibian populations on 4 continents, in 5 Canadian provinces, and in over 25 U.S. states. In order to understand host-pathogen dynamics, it is critical to establish baseline information on species susceptibility and the effects of natural stressors. The goal of my thesis research was to quantify the effects of anuran development and exposure to invertebrate predators on species-specific susceptibility to ranavirus. My experiments were designed in factorial arrangements, and consisted of exposure …

Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone
Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone
Department of Environmental Studies: Undergraduate Student Theses
The choice of a specific microhabitat represents a compromise among a number of different factors organisms use to monitor habitat suitability. Grassland vegetation structure can vary widely along environmental gradients over a relatively small area. This vegetation structure can have a large influence on habitat selection by grasshoppers (Orthoptera). However, it is not clear which vegetation characteristics are most important in determining grasshopper abundance. We found that plant biomass, plant species richness, and plant quality all have an effect on grasshopper abundance and distribution. We observe that these affects vary both within and among the two years of data collection. …

Biology Faculty Publications
The tadpole of Proceratophrys renalis is described based on specimens from Maceió, State of Alagoas, northeastern Brazil. At stage 35 the body is slightly dorso-ventrally depressed, ovoid in lateral, dorsal, and ventral views. Oral disc is ventral with lateral emarginations, surrounded by a single row of marginal papillae with a large gap on the upper labium. Labial tooth row formula is 2(2)/3(1 ). The analysis of internal oral anatomy revealed two possible characters that readily distinguish P. renalis from P. boiei, supporting the recent resurrection of P. renal is. Comparisons with available descriptions of the larvae for other species in …
Design Standards Within Constructed Wetlands For The Reduction Of Mosquito Populations In Clark County, Nevada, Phillip C. Bondurant
Design Standards Within Constructed Wetlands For The Reduction Of Mosquito Populations In Clark County, Nevada, Phillip C. Bondurant
UNLV Theses, Dissertations, Professional Papers, and Capstones
Wetlands are considered one of the most productive ecosystems in the world and provide many benefits to the environment. However, the slow moving and sometimes stagnant water created by the vegetation in the wetland creates an ideal environment for the proliferation of mosquitoes. Mosquitoes are the most important insect disease vector worldwide. The presence of mosquitoes within wetlands increases the risk of disease transmission among workers and visitors creating a public health concern. Effective design standards aimed at reducing mosquito breeding habitat should be implemented during the construction and planning phase of wetland development to effectively reduce the mosquito populations. …

Reconstructing Species Responses To Past Climatic Changes Using Niche Modeling And Genetic Data, Tereza Jezkova
UNLV Theses, Dissertations, Professional Papers, and Capstones
Glacial – interglacial cycles have a pronounced impact on species distributions and genetic structure. Many species shift their distributions to lower latitudes and altitudes during the colder glacial periods and expand northwards and up the elevation during warmer interglacial periods. Some species however are capable of adapting to changing environment which allows them to persist in place despite climatic changes. I explored how climatic changes after the last glacial maximum (LGM) effected two species inhabiting the deserts of western North America: one mammal (Chisel-toothed Kangaroo Rat, Dipodomys microps) and one reptile (Desert Horned Lizard, Phrynosoma platyrhinos). I used …
The Status Of Dwarfed Populations Of Short-Horned Lizards (Phrynosoma Hernandesi) And Great Plains Toads (Anaxyrus Cognatus) In The San Luis Valley, Colorado, Megan E. Lahti
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The San Luis Valley is a large valley formation in Colorado surrounded on either side by mountain ranges exceeding 4,267 m. Within the Valley, two of the 14 amphibian and reptile species are dwarfed: the short-horned lizard (Phrynosoma hernandesi) and the Great Plains toad (Anaxyrus cognatus). Since its initial reporting in 1968 and confirmation in 1981, no research further investigating this dwarfism has been conducted. I collected morphological measurements to determine the extent and patterns of dwarfism of both species. I then investigated the genetics of both species using mitochondrial DNA to determine whether they are …
Multi-Scale Perspectives On Paddlefish Populations: Implications For Species Conservation And Management, Brenda M. Pracheil
Multi-Scale Perspectives On Paddlefish Populations: Implications For Species Conservation And Management, Brenda M. Pracheil
School of Natural Resources: Dissertations, Theses, and Student Research
The Order of fishes containing paddlefish and sturgeon has been named the most endangered group of organisms on the planet by the International Union of Conservation of Nature (IUCN). Population trajectories of paddlefish, whose native range is entirely encompassed within the United States of America, are currently unknown, although the IUCN has considered them to have a high extinction risk in the wild. The declaration of the vulnerability of paddlefish to extinction, coupled with the global plight of other sturgeon species create urgency to establish population and species-level population trajectories. Moreover, this declaration creates a great need for swift management …

Estimates of survival for the young of a species are critical for population models. These models can often be improved by determining the effects of management actions and population abundance on this demographic parameter. We used multiple sources of data collected during 1982–2008 and a live-recapture dead-recovery modeling framework to estimate and model survival of Florida panther (Puma concolor coryi) kittens (age 0–1 year). Overall, annual survival of Florida panther kittens was 0.323 ± 0.071 (SE), which was lower than estimates used in previous population models. In 1995, female pumas from Texas (P. c. stanleyana) were …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research
The euryhaline, amphibious mangrove killifish Kryptolebias marmoratus is known to survive weeks out of water in moist environments. We tested the hypothesis that the skin is a site of osmo- and ionoregulation in K. marmoratus. We predicted that under terrestrial conditions, gill and skin remodeling would result in an enhanced role for skin and a diminished role for the gills in osmo- and ionoregulation. Fish were exposed to water—either freshwater (FW, 1‰) or hypersaline water (saltwater [SW], 45‰)—or air over a moist surface of FW or SW for 9 d and then recovered in water. When fish were emersed …

The Leptodactylus melanonotus group consists of 15 species, but references to skeletal characters are available for only three species: L. leptodactyloides, L. melanonotus, and L. diedrus. Leptodactylus nesiotus is a member of the melanonotus group known only from the type locality, Bonasse swamp, on the Southwestern peninsula of Trinidad, Trinidad and Tobago. This species has been categorized as vulnerable given its restricted distribution. Herein, we report the adult osteology of L. nesiotus, the skeletal characters are compared with the available data from other Leptodactylus species. A phylogenetic analysis recovers a paraphyletic L. melanonotus group relative to the L. …

Immunocontraception In Wild Horses (Equus Caballus) Extends Reproductive Cycling Beyond The Normal Breeding Season, Cassandra M.V. Nuñez, James S. Adelman, Daniel I. Rubenstein
Cassandra M.V. Nuñez
Although the physiological effects of immunocontraceptive treatment with porcine zona pellucida (PZP) have been well studied, little is known about PZP's effects on the scheduling of reproductive cycling. Recent behavioral research has suggested that recipients of PZP extend the receptive breeding period into what is normally the non-breeding season. To determine if this is the case, we compiled foaling data from wild horses (Equus caballus) living on Shackleford Banks, North Carolina for 4 years pre- and 8 years post-contraception management with PZP (pre-contraception, n = 65 births from 45 mares; post-contraception, n = 97 births from 46 mares). Gestation lasts …

Factors Influencing Long-Term Population Dynamics Of Pronghorn (Antilocapra Americana): Evidence Of An Allee Effect, Justin D. Hoffman, Hugh H. Genoways, Rachel R. Jones
University of Nebraska State Museum: Mammalogy Papers
Populations of pronghorn (Antilocapra americana) are subjected to multiple forms of density-dependent and density-independent regulation. Little is known about the combined effects of these variables across multiple populations throughout the landscape. The objectives of this study were to examine long-term trends in density and recruitment in pronghorn and to assess how different forms of regulation influence these trends. We used multiple density-dependent and density-independent explanatory variables in a model selection process to explain variation in pronghorn density and July fawn : doe ratios from 1955 to 1993 in 4 pronghorn management units in Nebraska. We also investigated levels …

Extinction is a natural process. Today, however, plant and animal species are disappearing world-wide at an accelerated pace. Based on current trends, half of the species on earth will be extinct within the next 100 years. The major cause of this phenomenon is human caused changes to the environment, which continue to increase - in Oregon and throughout the world.
Once lost, a species can never be recovered, and there is no way of knowing how useful it may have been. We do know that human beings and many of their industries depend on plant and animal products. About 50% …

Independent Study Project (ISP) Collection
Zebra are highly social ungulates that live in harems with a dominance hierarchy. This study attempted to determine if dominance rank within a herd of Burchell’s zebra (Equus burchelli) correlated to frequencies of other behaviors. It was predicted that adult zebra would display the most vigilance, with vigilance decreasing with dominance rank. This study took place at Ndarakwai Ranch in the west Kilimanjaro basin of northern Tanzania from 11/7/10 until 11/22/10. Scans (n=199), follows, and all-group observations were used to collect data on opportunistic sightings of Burchell’s zebra. Zebra were categorized into five age classes: stallion, adult females, sub-adults, juveniles, …

Review of the literature and recently available field notes from the collector of the type allows a reconsideration of the identity of the Linnaean name Rana typhonia. We provide evidence to demonstrate that the Linnaean species is neither a bufonid nor an Asiatic ranid, but a Neotropical hylid. Subsequently, we consider Rana typhonia as an older synonym of Rana venulosa Laurenti, 1768, redescribing its holotype under the new combination, Trachycephalus typhonius (Linnaeus, 1758).
