Bats Of Barbuda, Northern Lesser Antilles, Scott C. Pedersen, Peter A. Larsen, Hugh H. Genoways, Matthew Morton, Kevel C. Lindsay, Jerry Cindric Oct 2007

Bats Of Barbuda, Northern Lesser Antilles, Scott C. Pedersen, Peter A. Larsen, Hugh H. Genoways, Matthew Morton, Kevel C. Lindsay, Jerry Cindric

University of Nebraska State Museum: Mammalogy Papers

Five species of bats are known to occur on the Lesser Antillean island of Barbuda—Noctilio leporinus, Monophyllus plethodon, Brachyphylla cavernarum, Tadarida brasiliensis, and Molossus molossus. During the present study, two additional species of bats—Artibeus jamaicensis and Natalus stramineus—were added to the chiropteran fauna of the island. Although the ecological diversity of Barbuda is limited, this bat fauna matches those of islands in the region such as Antigua, Nevis, and St. Kitts. It is proposed that this biodiversity of bats is maintained because of the geology of Barbuda provides ample roosting sites and access to freshwater …

Thalamic Gating Of Auditory Responses In Telencephalic Song Control Nuclei, Melissa J. Coleman, Arani Roy, J. Martin Wild, Richard Mooney Sep 2007

Thalamic Gating Of Auditory Responses In Telencephalic Song Control Nuclei, Melissa J. Coleman, Arani Roy, J. Martin Wild, Richard Mooney

WM Keck Science Faculty Papers

In songbirds, nucleus Uvaeformis (Uva) is the sole thalamic input to the telencephalic nucleus HVC (used as a proper name), a sensorimotor structure essential to learned song production that also exhibits state dependent responses to auditory presentation of the bird’s own song (BOS). The role of Uva in influencing HVC auditory activity is unknown. Using in vivo extracellular and intracellular recordings in urethane-anesthetized zebra finches, we characterized the auditory properties of Uva and examined its influence on auditory activity in HVC and in the telencephalic nucleus interface (NIf), the main auditory afferent of HVC and a corecipient of Uva input. …

A Study Of The Mussels (Mollusca: Bivalvia: Unionidae) Of Symmes Creek And Tributaries In Jackson, Gallia And Lawrence Counties, Ohio, Michael A. Hoggarth, David A. Kimberly, Benjamin G. Van Allen Sep 2007

A Study Of The Mussels (Mollusca: Bivalvia: Unionidae) Of Symmes Creek And Tributaries In Jackson, Gallia And Lawrence Counties, Ohio, Michael A. Hoggarth, David A. Kimberly, Benjamin G. Van Allen

Biology and Earth Science Faculty Scholarship

Freshwater mussels (family Unionidae) are among the most threatened of Ohio's aquatic fauna. Interest in their biogeography has increased as their distribution and abundance has declined. This study was performed to assess the status of the mussels of Symmes Creek and it major tributaries in southern Ohio. Of the 24 species of mussels known to have inhabited this watershed, 16 were found alive in the system in 2004 and 2005 and two others were found as freshly dead shells. These species are thought to represent the extant mussel fauna in the system today. Of the remaining six species collected prior …

Animal Mind: Science, Philosophy, And Ethics, Bernard E. Rollin Sep 2007

Animal Mind: Science, Philosophy, And Ethics, Bernard E. Rollin

Sentience Collection

Although 20th-century empiricists were agnostic about animal mind and consciousness, this was not the case for their historical ancestors – John Locke, David Hume, Jeremy Bentham, John Stuart Mill, and, of course, Charles Darwin and George John Romanes. Given the dominance of the Darwinian paradigm of evolutionary continuity, one would not expect belief in animal mind to disappear. That it did demonstrates that standard accounts of how scientific hypotheses are overturned – i.e., by empirical disconfirmation or by exposure of logical flaws – is inadequate. In fact, it can be demonstrated that belief in animal mind disappeared as a result …

Animal Minds, Cognitive Ethology, And Ethics, Colin Allen, Marc Bekoff Sep 2007

Animal Minds, Cognitive Ethology, And Ethics, Colin Allen, Marc Bekoff

Sentience Collection

Our goal in this paper is to provide enough of an account of the origins of cognitive ethology and the controversy surrounding it to help ethicists to gauge for themselves how to balance skepticism and credulity about animal minds when communicating with scientists. We believe that ethicists’ arguments would benefit from better understanding of the historical roots of ongoing controversies. It is not appropriate to treat some widely reported results in animal cognition as if their interpretations are a matter of scientific consensus. It is especially important to understand why loose references to ‘‘cognitive ethology’’ by philosophers can signal ignorance …

Fisheries Research Report No. 163 - Spatial Scales Of Exploitation Among Populations Of Demersal Scalefish: Implications For Management. Part 1: Stock Status Of The Key Indicator Species For The Demersal Scalefish Fishery In The West Coast Bioregion., Department Of Fisheries, Western Australia Sep 2007

Fisheries Research Report No. 163 - Spatial Scales Of Exploitation Among Populations Of Demersal Scalefish: Implications For Management. Part 1: Stock Status Of The Key Indicator Species For The Demersal Scalefish Fishery In The West Coast Bioregion., Department Of Fisheries, Western Australia

Fisheries Research Reports

Final FRDC report - Project 2003/052

The levels of exploitation on dhufish and pink snapper across the West Coast Bioregion and for baldchin groper at the Abrolhos Islands are above international benchmark standards. This indicates that these stocks are currently being overfished and are therefore likely to be being depleted to levels below those necessary to ensure their long-term sustainability. The current reliance of the dhufish catch on a single recruitment pulse together with the extremely truncated age distribution of pink snapper indicates that both these stocks are particularly vulnerable.

The West Coast Demersal Scalefish Fishery is a multi-species fishery …

Managing The Recreational Catch Of Demersal Scalefish On The West Coast. Future Management Scenarios For Community Consideration, Jon Ford (Minister For Fisheries; The Kimberley, Pilbara And Gascoyne) Sep 2007

Managing The Recreational Catch Of Demersal Scalefish On The West Coast. Future Management Scenarios For Community Consideration, Jon Ford (Minister For Fisheries; The Kimberley, Pilbara And Gascoyne)

Fisheries Management Papers

This paper discusses the major issues around controlling the total recreational catch. It also considers some of the tools available to manage the catch to specific target levels. The sustainability of fish species must be a key driver. However, the impacts on the social amenity of recreational fishing must also be taken into account. Any particular tool, if used on its own and to its full extent, may be rather “blunt” in its application and its impacts unacceptable to large parts of the community. The most effective and acceptable management package will probably be a mix of tools, supported by …

Fruit Quality And Consumption By Songbirds During Autumn Migration, Susan B. Smith, Kathleen H. Mcpherson, Jeffrey M. Backer, Barbara J. Pierce, David W. Podlesak, Scott R. Mcwilliams Sep 2007

Fruit Quality And Consumption By Songbirds During Autumn Migration, Susan B. Smith, Kathleen H. Mcpherson, Jeffrey M. Backer, Barbara J. Pierce, David W. Podlesak, Scott R. Mcwilliams

Biology Faculty Publications

Seasonal fruits are an important food resource for small songbirds during autumn migration in southern New England. Therefore, conservation and management of important stopover sites used by migrating birds requires knowledge about nutritional requirements of songbirds and nutritional composition of commonly consumed fruits. We measured nutrient composition and energy density of nine common fruits on Block Island, Rhode Island, and conducted a field experiment to estimate consumption rates of three of these fruits by birds during autumn migration. Most common fruits on Block Island contained primarily carbohydrates (41.3–91.2% dry weight), and little protein (2.6–8.6%) and fat (0.9–3.7%), although three contained …

Subcutaneous Fsh Implants, Colette Floyd Aug 2007

Subcutaneous Fsh Implants, Colette Floyd

All Theses

Superovulation is an assisted reproductive technique used to hyperstimulate the ovaries in an attempt to proliferate desirable genetics by increasing the number of dominant follicles and oocytes available per estrous cycle. Unfortunately, the process is inefficient and costly due to FSH injection protocols, labor requirements, and animal stress. A sustained release implant as a novel FSH delivery mechanism could increase the efficiency and utility while reducing cost and animal stress. The objectives of these experiments were: to design and fabricate a sustained FSH release implant and evaluate the amount of FSH released in-vitro and in-vivo.
Polyethylene glycol diacrylate (PEGDA) was …

Examination Of The Allee Effect On Postlarval Recruitment And Post Settlement Survival In The Caribbean Spiny Lobster Panulirus Argus, Adrianna Zito Aug 2007

Examination Of The Allee Effect On Postlarval Recruitment And Post Settlement Survival In The Caribbean Spiny Lobster Panulirus Argus, Adrianna Zito

All Theses

Positive density dependence (the Allee effect) has been reported in a number of species that are attracted to conspecific cues. This effect has been shown to influence the settlement of many species of marine invertebrates. Caribbean spiny lobsters are gregarious den dwellers attracted to conspecific cues. Previous studies have suggested that the benefit of conspecific attraction is a reduced predation risk by decreasing the time to find crevice shelters (the guide effect) or by cooperative group defense once sharing shelters. I tested a third hypothesis that attraction to conspecific cues increases the settlement of lobster postlarvae into the highest quality …

Thrombocyte Response To Lipopolysaccharide In Stress Induced Broiler Chicks, Farzana Ferdous Aug 2007

Thrombocyte Response To Lipopolysaccharide In Stress Induced Broiler Chicks, Farzana Ferdous

All Theses

The role of thrombocytes, nucleated blood leukocytes, on immune responses in chickens fed diets supplemented with vitamin C has not been studied in the past. This study investigates the effects of three types of diets(control, control with corticosterone, and control with corticosterone and vitamin C) in 14-day old broiler chicks on the expression of pro-inflammatory cytokines IL-1beta, IL-6, and IL-12 in thrombocytes. In addition, the effect of LPS, a microbial component to which broiler chicks can be exposed, on the expression of these pro-inflammatory cytokines was investigated. After two weeks of feeding, blood samples from the chicks were collected and …

Feeding Performance In Hawaiian Stream Goby Fishes: Morphological And Functional Analysis, Takashi Maie Aug 2007

Feeding Performance In Hawaiian Stream Goby Fishes: Morphological And Functional Analysis, Takashi Maie

All Theses

Distributions of Hawaiian stream fishes are typically interrupted by waterfalls that divide streams into lower and upper segments. Larvae hatched upstream are flushed into the ocean, and must climb these waterfalls to reach adult habitats when returning back to freshwater as part of an amphidromous life cycle. Stream surveys and studies of climbing performance show that Lentipes concolor can reach fast-flowing upper stream segments, but that Awaous guamensis reaches only slower, lower stream segments. Gut content analyses for these two species indicate that diet differs between them only by 10% or less dry weight for most major components (mostly green …

The Influence Of Early Experience On, And Inheritance Of, Cerebral Lateralization, Culum Brown, Jac Western, Victoria A. Braithwaite Aug 2007

The Influence Of Early Experience On, And Inheritance Of, Cerebral Lateralization, Culum Brown, Jac Western, Victoria A. Braithwaite

Veterinary Science and Medicine Collection

Cerebral lateralization refers to the lateralized partitioning of cognitive function in either hemisphere of the brain. Using a standard detour test, we investigated lateralized behaviour in wild-caught, female poeciliid fish, Brachyraphis (=Brachyrhaphis) episcopi, from high- and low-predation areas. Wild fish were bred and their offspring reared under controlled laboratory conditions. These laboratory-reared fish were screened in the same laterality assays as their parents. We observed differences between wild-caught females and their laboratory-reared female offspring in the pattern of lateralization (tendency to use one hemisphere over the other to process information). Conversely, the strength of lateralization (consistency of hemispherical bias) was …

Landscape Ecology Of Crayfish (Decapoda: Cambaridae) In West-Central Indiana, Jacob L. Burskey Aug 2007

Landscape Ecology Of Crayfish (Decapoda: Cambaridae) In West-Central Indiana, Jacob L. Burskey

All-Inclusive List of Electronic Theses and Dissertations

I investigated the distribution, zoogeography, and habitat associations of crayfish (Decapoda: Cambaridae) in an area of west central Indiana containing glaciated and unglaciated regions. I first sampled 180 streams within Vigo, Clay, Owen, Sullivan, Greene, and Knox counties to establish spatial distributions of crayfish species and gather information on natural history and site specific habitat conditions. Ten species were found; Cambarus (Tubericambarus) polychromatus, Cambarus (Lacunicambarus) sp.A, Cambarus (Erebicambarus) laevis, Fallicambarus (Creaserinus)fodiens, Procambarus (Girardiella) gracilis, Procambarus (Ortmannicus) acutus, Orconectes (Triscellescens) immunis, Orconectes ( Gremicambarus) virilis, Orconectes ( Crockerinus) propinquus, - Orconectes (Faxinous) indianensis. The two rarest species were 0. indianensis (collected …

Pratt, P. T. Nelson, M. R. Stevens, Eric N. Jellen, Craig E. Coleman, Daniel J. Fairbanks, A. Bonifacio, Michael J. Maughan

Faculty Publications

Quinoa (Chenopodium quinoa Willd.) is a staple food crop for millions of impoverished rural inhabitants of Andean South America where it has been cultivated for millennia. Interest in quinoa, due largely to its superior nutritional characteristics, is fuelling a growing export market and has led to an increased focus on genetic research and the development of quinoa breeding programmes throughout South America. The success of these breeding programmes will rely heavily on the development of core germplasm collections and germplasm conservation. We report the development of a set of fluorescence-tagged microsatellite molecular markers that can be used to characterize genetic …

Effects Of Calcium Availability On The Reproductive Output Of Insectivorous Bats, Christina M. Booher Aug 2007

Effects Of Calcium Availability On The Reproductive Output Of Insectivorous Bats, Christina M. Booher

All-Inclusive List of Electronic Theses and Dissertations

Reproduction is a period of high calcium demand in vertebrates, and calcium deficiency can limit reproductive output in mammals. Insects are a poor calcium source, suggesting that insectivorous species are more likely to be calcium deficient. Pregnant big brown bats (Eptesicus fuscus) consume 10 times less calcium than they are estimated to require. To accommodate calcium demand during pregnancy, many mammals mobilize more calcium from the skeleton, and extensive bone loss has been observed in some bats during pregnancy. A conflict may arise between the female and developing embryo over allocation of limited calcium supplies, which could limit reproductive output …

Cloning And Characterization Of The Salt Overly Sensitive 1 (Sos1) Gene In Chenopodium Quinoa Willd., Taylor Brian Turner Jul 2007

Cloning And Characterization Of The Salt Overly Sensitive 1 (Sos1) Gene In Chenopodium Quinoa Willd., Taylor Brian Turner

Theses and Dissertations

Salt tolerance is a commercially important trait that affects plant species around the globe. Cellular response to saline environments is a well studied but complex system that is far from being completely understood. The SALT OVERLY SENSITIVE 1 (SOS1) gene is a critical component of salt tolerance in many species, encoding a plasma membrane Na+/H+ antiporter that plays an important role in germination and growth in saline environments. Here we report a preliminary investigation of salt tolerance in quinoa (Chenopodium quinoa Willd.). Quinoa is a halophytic grain crop of the Chenopodiaceae family with impressive nutritional content and an increasing world-wide …

Sampling A Littoral Fish Assemblage: Comparison Of Small-Mesh Fyke Netting And Boat Electrofishing, Carl R. Ruetz Iii, Donald G. Uzarski, Damon M. Krueger, Edward S. Rutherford Jul 2007

Sampling A Littoral Fish Assemblage: Comparison Of Small-Mesh Fyke Netting And Boat Electrofishing, Carl R. Ruetz Iii, Donald G. Uzarski, Damon M. Krueger, Edward S. Rutherford

Peer-reviewed scientific publications

We compared small-mesh (4-mm) fyke netting and boat electrofishing for sampling a littoral fish assemblage in Muskegon Lake, Michigan. We hypothesized that fyke netting selects for small-bodied fishes and electrofishing selects for large-bodied fishes. Three sites were sampled during May (2004 and 2005), July (2005 only), and September (2004 and 2005). We found that the species composition of captured fish differed considerably between fyke netting and electrofishing based on nonmetric multidimensional scaling (NMDS). Species strongly associated with fyke netting (based on NMDS and relative abundance) included the brook silverside Labidesthes sicculus, banded killifish Fundulus diaphanus, round goby Neogobius melanostomus, mimic …

Development And Characterization Of Microsatellite Markers For The Grain Amaranths (Amaranthus Spp. L.), Melanie Ann Mallory Jul 2007

Development And Characterization Of Microsatellite Markers For The Grain Amaranths (Amaranthus Spp. L.), Melanie Ann Mallory

Theses and Dissertations

The grain amaranths (Amaranthus hypochondriacus L., A. cruentus L., and A. caudatus L.) are important pseudocereals native to the Americas that have received increased attention for their nutritional content, specifically their balance of amino acids. The objective of this project was to produce and characterize a set of highly informative, reproducible microsatellite markers for the grain amaranths. A total of 1457 clones were sequenced from three genomic libraries enriched for the microsatellite motifs AAC, AAT and AC. Of these, 353 (24%) contained unique microsatellites. An additional 29 microsatellite loci were identified among 728 BAC-end sequences of a newly developed amaranth …

The Prolamins Of Pearl Millet, Christian B. Ricks Jul 2007

The Prolamins Of Pearl Millet, Christian B. Ricks

Theses and Dissertations

Although work on the prolamins of pearl millet (Pennisetum glaucum) has revealed partial amino acid sequences for several alcohol-soluble storage proteins (Marcellino et al. 2002) the genes encoding them have not yet been isolated. We constructed a cDNA library from developing P. glaucum seed tissue and screened it using maize zein gene probes to isolate several α-prolamin-like gene sequences. The proteins encoded by these genes generally fall into two size classes: 20.6kD and 27.1kD, which we call the 21kD and 27kD pennisetins. Both proteins are similar in composition and sequence to α-prolamins from maize, sorghum and Coix. Protein bodies that …

Bovine Respiratory Disease In Feedlot Cattle: Phenotypic, Environmental, And Genetic Correlations With Growth, Carcass, And Longissimus Muscle Palatability Traits, G. D. Snowder, L. Dale Van Vleck, L. V. Cundiff, G. L. Bennett, M. Koohmaraie, M. E. Dikeman

Department of Animal Science: Faculty Publications

Bovine respiratory disease (BRD) is the most costly feedlot disease in the United States. Selection for disease resistance is one of several possible interventions to prevent or reduce the economic loss associated with animal disease and to improve animal welfare. Undesirable genetic relationships, however, may exist between production and disease resistance traits. The objectives of this study were to estimate the phenotypic, environmental, and genetic correlations of BRD with growth, carcass, and LM palatability traits. Health records on 18,112 feedlot cattle over a 15-yr period and slaughter data on 1,627 steers over a 4-yr period were analyzed with bivariate animal …
