Testing Factors Influencing Identification Rates Of Similar Species During Abundance Surveys, Anne Louise Schaefer, Paul Lukacs, Michelle L. Kissling

Wildlife Biology Faculty Publications

Most abundance estimation methods assume that all sampled individuals are identified correctly. In practice, this assumption may be difficult to meet and can bias abundance estimates, especially when morphologically similar species overlap in range. Over the past 2 decades, Kittlitz's Murrelet (Brachyramphus brevirostris) populations appear to have declined across parts of their Alaskan range, where they co-occur with the Marbled Murrelet (B. marmoratus). Recently, the reliability of Kittlitz's Murrelet declines have been questioned due to variability and uncertainty in species identification between the 2 species. We conduced a field experiment to quantify misidentification and partial identification …

Suitability Of Great South Bay, New York To Blooms Of Pfiesteria Piscicida And P. Shumwayae Prior To Superstorm Sandy, October 29, 2012, Pawel Tomasz Zablocki

Theses and Dissertations

Pfiesteria piscicida and P. shumwayae are toxic dinoflagellates implicated in massive fish kills in North Carolina and Maryland during 1990s.

This study employs i nformation gathered from relevant literature on temperature, salinity, dissolved oxygen, pH, turbulent mixing, and dissolved nutrients, bacteria, algae, microzooplankton, mesozooplankton, bivalve m ollusks, finfish, and other toxic dinoflagellates, which influence Pfiesteria population dynamics. The research focused on whether conditions in the Great South Bay, Long Island, New York were suitable to blooms of Pfiesteria species prior to the passage of superstorm …

Effect Of Aging Time And Retail Displaying Period With A Short-Term Temperature Abuse On Color Stability Of Two Beef Muscles, Derico Setyabrata, Hyun-Wook Kim, Yuan H. Brad Kim

The Summer Undergraduate Research Fellowship (SURF) Symposium

Meat color and tenderness are two most important quality factors affecting consumers’ decision on meat purchasing. Post-mortem meat aging has been widely practiced to improve palatability attributes, but could be adversely related to meat color. In particular, temperature abuse during aging or retail display can negatively affect the color stability of aged meat. The objective of this study was to determine the effect of aging time and short-term temperature abuse during display on color stability of two beef muscles (M. longissimus dorsi, LD and semitendinosus, ST). LD and ST muscles were separated from three beef carcasses, vacuum-packaged …

A Transcriptomal Analysis Of Bovine Oviductal Epithelial Cells Collected During The Follicular Phase Versus The Luteal Phase Of The Estrous Cycle, K. L. Cerny, E. Garrett, A. J. Walton, L. H. Anderson, P. J. Bridges

Animal and Food Sciences Faculty Publications

BACKGROUND: Reproductive success depends on a functional oviduct for gamete storage, maturation, fertilization, and early embryonic development. The ovarian-derived steroids estrogen and progesterone are key regulators of oviductal function. The objective of this study was to investigate luteal and follicular phase-specific oviductal epithelial cell function by using microarray-based transcriptional profiling, to increase our understanding of mRNAs regulating epithelial cell processes, and to identify novel genes and biochemical pathways that may be found to affect fertility in the future.

METHODS: Six normally cycling Angus heifers were assigned to either luteal phase (LP, n = 3) or follicular phase (FP, …

Responses Of Primate Frontal Cortex Neurons During Natural Vocal Communication, Cory T. Miller, A. Wren Thomas, Samuel U. Nummela, Lisa A. De La Mothe

Psychological Sciences and Counseling Faculty Research

The role of primate frontal cortex in vocal communication and its significance in language evolution have a controversial history. While evidence indicates that vocalization processing occurs in ventrolateral prefrontal cortex neurons, vocal-motor activity has been conjectured to be primarily subcortical and suggestive of a distinctly different neural architecture from humans. Direct evidence of neural activity during natural vocal communication is limited, as previous studies were performed in chair-restrained animals. Here we recorded the activity of single neurons across multiple regions of prefrontal and premotor cortex while freely moving marmosets engaged in a natural vocal behavior known as antiphonal calling. Our …

A Dual Function Of White Coloration In A Nocturnal Spider Dolomedes Raptor (Araneae: Pisauridae), Tai-Shen Lin, Shichang Zhang, Chen-Pan Liao, Eileen A. Hebets, I-Min Tso

Eileen Hebets Publications

Nocturnal animals frequently possess seemingly conspicuous color patterns that can function in a variety of ways (e.g. prey attraction, camouflage, predator avoidance, etc.). The use of color patterns in intraspecific signaling, especially reproductive activities, in nocturnal animals has received relatively little attention. This study tested for a dual function of color in the nocturnal fishing spider, Dolomedes raptor (Araneae: Pisauridae), whose males develop dimorphic white stripes at sexual maturation. We tested for a role in foraging as well as mate assessment. First, quantifications of the natural variation of male stripes indicated a correlation between stripe area and male body size …

Beef Cattle Management Systems For Estrus Synchronization And Heifer Development, Hazy Rae Nielson

Department of Animal Science: Dissertations, Theses, and Student Research

Four experiments were conducted to evaluate estrus synchronization and heifer development systems. In the first experiment delaying AI 19 h following GnRH administration in a hybrid estrus detection and time AI protocol was evaluated. Final pregnancy rate was not different among heifers detected in estrus, AI at the time GnRH administration, or delayed AI. The second study compared the effect of melengestrol acetate (MGA) -PG and 14-d controlled internal drug release (CIDR) -PG estrus synchronization protocols on estrus response and pregnancy rates of 311 d old heifers. Final pregnancy rate was similar between CIDR and MGA treatment groups. The objective …

Dietary Strategies For Mitigation Of Methane Production By Growing And Finishing Cattle, Anna C. Pesta

Department of Animal Science: Dissertations, Theses, and Student Research

Interest in reducing methane (CH₄) emissions by cattle has increased recently. Loss of feed energy as CH₄ represents both an environmental concern and an energetic loss to the animal. Manipulation of dietary composition has proven to be an effective mitigation strategy. Experiments were conducted to evaluate the effect of several dietary characteristics on CH₄ production in growing and finishing cattle, and to develop a novel, non-invasive method for quantifying emissions from animals in a production setting. Short-term gaseous emissions of CH₄ and carbon dioxide (CO₂) were measured and the CH₄:CO_{2 …}

Evaluation Of Reduced Subsets Of Single Nucleotide Polymorphisms For The Prediction Of Age At Puberty In Sows, Katherine L. Lucot, Matthew L. Spangler, Melanie D. Trenhaile, Stephen D. Kachman, Daniel C. Ciobanu

Department of Animal Science: Faculty Publications

Genomic information could be used efficiently to improve traits that are expensive to measure, sex limited or expressed late in life. This study analyzed the phenotypic variation explained by major SNPs and windows for age at puberty in gilts, an indicator of reproductive longevity. A genome-wide association study using 56,424 SNPs explained 25.2% of the phenotypic variation in age at puberty in a training set (n = 820). All SNPs from the top 10% of 1-Mb windows explained 33.5% of the phenotypic variance compared to 47.1% explained by the most informative markers (n = 261). In an evaluation population, consisting …

Habitat Use By Spruce Grouse In A Fragmented System, Laurel A. Hill

All NMU Master's Theses

The spruce grouse is a boreal obligate species that has been protected in Michigan since 1915 (Ammann 1963). Despite protection, the status of spruce grouse is uncertain in Michigan and other parts of the Midwest, and there have been few attempts at large-scale surveys or monitoring (Williamson et al. 2008). I studied a population of spruce grouse near the southern edge of their range on the Yellow Dog Plains in Marquette County, Michigan.

I investigated fecal pellet counts as a possible method to assess spruce grouse presence and habitat use. My results validated the use of fecal pellet occurrence as …

This study focuses on the Saco estuary, the tidal portion of the Saco River, which drains the largest watershed in southern Maine. With headwaters in the White Mountains of New Hampshire, the watershed encompasses more than 4,400 km², and provides clean healthy drinking water to over 100,000 people living and working in communities in southern Maine.

When the study began in 2009, very little was known about the ecology of the Saco estuary. Researchers at the University of New England and the Wells National Estuarine Research Reserve employed the process of collaborative learning to bring together people who …

An Analysis Of The Interaction Of Methylphenidate And Nicotine In Adolescent Rats: Effects On Bdnf, Elizabeth D. Freeman

Electronic Theses and Dissertations

This investigation was an analysis of the interaction of adolescent exposure to methylphenidate (MPH; trade name: Ritalin) on nicotine sensitization and conditioned place preference (CPP) in a rodent model and underlying mechanisms of this effect. Animals were treated IP with 1 mg/kg MPH or saline using a ―school day‖ regimen of five days on, two days off, from postnatal day (P) 28-50. During the final two weeks of MPH treatment, animals were either behaviorally sensitized to nicotine (0.5 mg/kg free base) or saline for 10 days, or conditioned to nicotine or saline using the CPP behavioral paradigm. In addition, three …

Analysis Of Variables Related To Corridor Use By Ocelots And Bobcats In South Texas, Sarah E. Nordlof

Theses and Dissertations - UTB/UTPA

Biologists estimate that less than 50 endangered ocelots (Leopardus pardalis) remain in the United States, restricted to two small populations in Cameron and Willacy Counties located in deep south Texas. Conversely, bobcats (Lynx rufus) are abundant in south Texas; however, two of the biggest threats to both species are vehicle collisions and habitat fragmentation. To mitigate these threats, the installation of wildlife crossings has been proposed to decrease the number of road mortalities, and wildlife corridors have been suggested as a useful tool for providing increased habitat connectivity. However, research on ocelot use of corridors and wildlife crossings in Texas …

Unraveling Host-Vector-Arbovirus Interactions By Two-Gene High Resolution Melting Mosquito Bloodmeal Analysis In A Kenyan Wildlife-Livestock Interface, David Omondi, Daniel K. Masiga, Yvonne Ukamaka Ajamma, Burtram C. Fielding, Laban Njoroge, Jandouwe Villinger

All Peer-Reviewed Publications

The blood-feeding patterns of mosquitoes are directly linked to the spread of pathogens that they transmit. Efficient identification of arthropod vector bloodmeal hosts can identify the diversity of vertebrate species potentially involved in disease transmission cycles. While molecular bloodmeal analyses rely on sequencing of cytochrome b (cyt b) or cytochrome oxidase 1 gene PCR products, recently developed bloodmeal host identification based on high resolution melting (HRM) analyses of cyt b PCR products is more cost-effective. To resolve the diverse vertebrate hosts that mosquitoes may potentially feed on in sub-Saharan Africa, we utilized HRM profiles of both cyt b and 16S …

Mammalian Records From Southwestern Kansas And Northwestern Oklahoma, Including The First Record Of Crawford’S Desert Shrew (Notiosorex Crawfordi) From Kansas, Cody A. Dreier, Keith Geluso, Jennifer D. Frisch, Brittney N. Adams, Alyx R. Lingenfelter, Anthony E. Bridger, Patricia Freeman, Cliff Lemen, Jeremy A. White, Brett R. Andersen, Hans W. Otto, Curtis J. Schmidt

School of Natural Resources: Faculty Publications

Mammalian distributions are constantly changing. Some distributional shifts reflect habitat change, climate change, and human transplantations; thus, such shifts are due to actual expansions or contractions of populations. However, other species ranges that appear to shift as the result of new records being added to known distributional limits actually might reflect populations that previously were undetected due to a lack of past surveys or species that are difficult to detect. In 2013, multiple techniques were employed to document mammalian distributional records in southwestern Kansas and northwestern Oklahoma. We discovered three new county records in Morton County, Kansas (Crawford’s Desert Shrew, …

In 2006, a marked increase in harbor porpoise Phocoena phocoena strandings were reported in the Pacific Northwest of the USA, resulting in the declaration of an unusual mortality event (UME) for Washington and Oregon to facilitate investigation into potential causes. The UME was in place during all of 2006 and 2007, and a total of 114 porpoises stranded during this period. Responders examined 95 porpoises; of these, detailed necropsies were conducted on 75 animals. Here we review the findings related to this event and how these compared to the years immediately before and after the UME. Relatively equal numbers among …

Epidemiological Associations Between Brachycephaly And Upper Respiratory Tract Disorders In Dogs Attending Veterinary Practices In England, Dan G. O'Neill, Caitlin Jackson, Jonathan H. Guy, David B. Church, Paul D. Mcgreevy, Peter Thomson, Dave C. Brodbelt

Epidemiology Collection

Background: Brachycephalic dog breeds are increasingly common. Canine brachycephaly has been associated with upper respiratory tract (URT) disorders but reliable prevalence data remain lacking. Using primary-care veterinary clinical data, this study aimed to report the prevalence and breed-type risk factors for URT disorders in dogs. Results: The sampling frame included 170,812 dogs attending 96 primary-care veterinary clinics participating within the VetCompass Programme. Two hundred dogs were randomly selected from each of three extreme brachycephalic breed types (Bulldog, French Bulldog and Pug) and three common small-to medium sized breed types (moderate brachycephalic: Yorkshire Terrier and non-brachycephalic: Border Terrier and West Highland …

Selective Impact Of Disease On Coral Communities: Outbreak Of White Syndrome Causes Significant Total Mortality Of Acropora Plate Corals, Jean-Paul A. Hobbs, Ashley J. Frisch, Stephen J. Newman, Corey B. Wakefield

Fisheries Research Articles

Coral diseases represent a significant and increasing threat to coral reefs. Among the most destructive diseases is White Syndrome (WS), which is increasing in distribution and prevalence throughout the Indo-Pacific. The aim of this study was to determine taxonomic and spatial patterns in mortality rates of corals following the 2008 outbreak of WS at Christmas Island in the eastern Indian Ocean. WS mainly affected Acropora plate corals and caused total mortality of 36% of colonies across all surveyed sites and depths. Total mortality varied between sites but was generally much greater in the shallows (0–96% of colonies at 5 m …

Parent-Offspring Resemblance In Colony-Specific Adult Survival Of Cliff Swallows, Charles R. Brown, Erin A. Roche, Mary Bomberger Brown

School of Natural Resources: Faculty Publications

Survival is a key component of fitness. Species that occupy discrete breeding colonies with different characteristics are often exposed to varying costs and benefits associated with group size or environmental conditions, and survival is an integrative net measure of these effects. We investigated the extent to which survival probability of adult (≥ 1-year old) cliff swallows (Petrochelidon pyrrhonota) occupying different colonies resembled that of their parental cohort and thus whether the natal colony had long-term effects on individuals. Individuals were cross-fostered between colonies soon after hatching and their presence as breeders monitored at colonies in the western Nebraska …
