Geese, Ducks And Coots, John L. Cummings

Wildlife Damage Management Technical Series

Canada geese, snow geese, ducks, and American coots all have been implicated in agricultural crop and turf damage. Canada geese and snow geese that graze on winter wheat and rye crops can reduce subsequent grain and vegetative yields. Canada geese also cause serious damage to sprouting soybeans in spring and to standing cornfields in the autumn. The most common damage to agricultural resources associated with geese results from consumption of crops. Other impacts involve unacceptable accumulations of feces in pastures, trampling of emerging crops, and increased erosion and runoff from fields where the cover crop has been grazed. Canada geese …

Exploring The Relationship Between Behaviour And Neurochemistry In The Polyphenic Spider, Anelosimus Studiosus (Araneae: Theridiidae), Jennifer B. Price

Electronic Theses and Dissertations

The importance of social behaviour is evident in human society, but there are both costs and benefits associated with cooperation and sociality throughout the animal kingdom. At what point do the benefits outweigh the costs, and when do selective pressures favour sociality and colonization over solitude and independence? To investigate these questions, we have focused on an anomalous species of spider, Anelosimus studiosus, also known now as the northern social spider. Throughout its broad range, A. studiosus is solitary and aggressive, but recently, colonies of cooperative and social individuals have been observed at northern latitudes. This leads to two …

Maternity Colony Of Northern Long-Eared Myotis (Myotis Septentrionalis) In A Human-Made Structure In Nebraska, Rachel M. Stein, Jeremy A. White

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The Northern Long-eared Myotis (Myotis septentrionalis) occurs across eastern North America, and its range extends west into the Great Plains of the United States. Summer roosts of M. septentrionalis in the Great Plains are not well documented. Herein we describe a maternity colony of M. septentrionalis using small, elevated structures (i.e., cabins) in southeastern Nebraska. Cabins were in a small parcel of upland deciduous forest about 1.6 km from the Missouri River. The maternity colony was observed roosting in a space between the outer and inner walls of three different cabins from 21 June to 8 October 2014. …

Comparison Of Real-Time Pcr And Elisa-Based Methods For The Detection Of Beef And Pork In Processed Meat Products, Adam T. Perestam, Kayleigh K. Fujisaki, Omar Nava, Rosalee S. Hellberg

Food Science Faculty Articles and Research

Two commonly used methodologies for species detection within processed meat products are real-time polymerase chain reaction (PCR), a DNA-based method, and enzyme-linked immunosorbent assay (ELISA), a protein-based method. In this study, a real-time PCR assay was compared to a commercial ELISA kit based on sensitivity, specificity, agreement among duplicate samples, cost, time, and ease of use. Fifteen reference samples containing known percentages (0.1–99.9%, w/w) of pork and beef were analyzed in duplicate using both methods. Thirty commercial products, including sausages, pet treats, and canned meats, were also tested in duplicate with each method. Reference sample analysis showed real-time PCR was …

Automated Detection Of Deep-Sea Animals, Dallas J. Hollis, Duane Edgington, Danelle Cline

STAR Program Research Presentations

The Monterey Bay Aquarium Research Institute routinely deploys remotely operated underwater vehicles equipped with high definition cameras for use in scientific studies. Utilizing a video collection of over 22,000 hours and the Video Annotation and Reference System, we have set out to automate the detection and classification of deep-sea animals. This paper serves to explore the pitfalls of automation and suggest possible solutions to automated detection in diverse ecosystems with varying field conditions. Detection was tested using a saliency-based neuromorphic selective attention algorithm. The animals that were not detected were then used to tune saliency parameters. Once objects are detected, …

Vocal Individuality And Species Divergence In The Contact Calls Of Banded Penguins, Livio Favaro, Claudia Gili, Cristiano Da Rugna, Guido Gnone, Chiara Fissore, Daniel Sanchez, Alan G. Mcelligott, Marco Gamba, Daniela Pessani

Bioacoustics Collection

Penguins produce contact calls to maintain social relationships and group cohesion. Such vocalisations have recently been demonstrated to encode individual identity information in the African penguin. Using a source-filter theory approach, we investigated whether acoustic cues of individuality can also be found in other Spheniscus penguins and the acoustic features of contact calls have diverged within this genus. We recorded vocalisations from two ex-situ colonies of Humboldt penguin and Magellanic penguin (sympatric and potentially interbreeding in the wild) and one ex-situ group of African penguins (allopatric although capable of interbreeding with the other two species in captivity). We measured 14 …

Goats Display Audience-Dependent Human-Directed Gazing Behaviour In A Problem-Solving Task, Christian Nawroth, Jemma M. Brett, Alan G. Mcelligott

Social Cognition Collection

Domestication is an important factor driving changes in animal cognition and behaviour. In particular, the capacity of dogs to communicate in a referential and intentional way with humans is considered a key outcome of how domestication as a companion animal shaped the canid brain. However, the lack of comparison with other domestic animals makes general conclusions about how domestication has affected these important cognitive features difficult. We investigated human-directed behaviour in an ‘unsolvable problem’ task in a domestic, but non-companion species: goats. During the test, goats experienced a forward facing or an away facing person. They gazed towards the forward …

The Effect Of Home Range Estimation Techniques On Habitat Use Analysis, Brendon Quinton

USF Tampa Graduate Theses and Dissertations

The term “home range” refers to the area in which an animal spends most of its time during everyday activities. This study examined the effects of four different home range estimation techniques on the proportions of habitats located therein. The study utilized a point dataset collected for twenty individual Florida Black Bears (Ursus americanus floridanus), occurring in five different areas throughout the state of Florida. Each dataset was used to create home ranges using the following techniques: (1) Minimum Convex Polygon, (2) Kernel Density Estimation, (3) Characteristic Hull Polygon, and (4) Time-Geographic Density Estimation, a new home range …

Laterality Strength Is Linked To Stress Reactivity In Port Jackson Sharks (Heterodontus Portusjacksoni), Evan E. Byrnes, Catarina Vila Pouca, Culum Brown

Laterality Collection

Cerebral lateralization is an evolutionarily deep-rooted trait, ubiquitous among the vertebrates and present even in some invertebrates. Despite the advantages of cerebral lateralization in enhancing cognition and facilitating greater social cohesion, large within population laterality variation exists in many animal species. It is proposed that this variation is maintained due links with inter-individual personality trait differences. Here we explored for lateralization in Port Jackson sharks (Heterodontus portusjacksoni) using T-maze turn and rotational swimming tasks. Additionally, we explored for a link between personality traits, boldness and stress reactivity, and cerebral lateralization. Sharks demonstrated large individual and sex biased laterality …

Impacts From The Use Of Antibiotics In Livestock: Methods Of Transmission Of Antibiotic Resistance From Livestock To Humans, Kristin M. Walden

Biology: Student Scholarship & Creative Works

Antibiotic use in livestock production has been around since the 1950s. Antibiotic feed is used in livestock and other meat producing animals for three reasons: illness prevention, illness treatment, and growth promotion. Unfortunately, since the time that antibiotics were first invented, antibiotic resistant bacteria have become a threat to public health. There are many studies showing methods of transmission of antibiotic resistance from livestock to humans. Antibiotic resistance can spread from livestock to soil, water, insects, and food, which ultimately comes into contact with humans. A proposed study to measure antibiotic resistance when eliminating antibiotic feed will provide a hypothesis …

Sensory Modalities Underlying The Escape Response Of The Cricket, Acheta Domesticus, To Looming Stimuli, Ariel M. Childs

Senior Honors Projects, 2010-2019

In order to prevent injury or capture by a predator, animals have evolved escape behavior. Despite offering a more realistic, multimodal, approximation of an approaching predator, looming stimuli have rarely been used to evoke escape behavior in crickets. Wind stimuli, however, have been used on a variety of insects, including crickets where it has been found that direction of escape is directly correlated to the angle of incoming wind stimuli. Wind stimuli are detected by sensilla trichodea, small filiform hairs covering the cerci of crickets, locusts and cockroaches. Despite having other complex sensory systems, such as antennae and vision, …

Are Domestic Pigs (Sus Scrofa Domestica) Able To Use Complex Human-Given Cues To Find A Hidden Reward?, Christian Nawroth, Mirjam Ebersbach, Eberhard Von Borell

Social Cognition Collection

Understanding human-animal interactions in livestock production systems is crucial for improving animal welfare. It is therefore of general interest to investigate how livestock animals obtain information from humans. By using an object-choice paradigm, we investigated whether domestic pigs (n = 4) are able to use a variety of human-given cues, such as different pointing gestures, to find a hidden food reward. In Experiment 1, an experimenter pointed towards a baited location in front of the pig while the extent of the protrusion of his hand from the upper body was varied. Pigs had problems using pointing gestures that did not …

An Ethogram For Benthic Octopods (Cephalopoda: Octopodidae), Jennifer Mather, Jean S. Alupay

Physiology Collection

The present paper constructs a general ethogram for the actions of the flexible body as well as the skin displays of octopuses in the family Octopodidae. The actions of 6 sets of structures (mantle–funnel, arms, sucker–stalk, skin–web, head, and mouth) combine to produce behavioral units that involve positioning of parts leading to postures such as the flamboyant, movements of parts of the animal with relation to itself including head bob and grooming, and movements of the whole animal by both jetting in the water and crawling along the substrate. Muscular actions result in 4 key changes in skin display: (a) …

Evaluation Of Seizure Threshold As An Early Behavioral Marker Of Disease Progression In The Mouse Model Of Mucopolysaccharidosis Iiia, Pamela Santiago

Dissertations, Masters Theses, Capstones, and Culminating Projects

Mucopolysaccharidosis IIIA (MPS IIIA) is a lysosomal storage disease caused by a mutation in the gene that codes for the enzyme heparan sulfamidase. The decreased enzyme activity of heparan sulfamidase results in the accumulation of heparan sulfate (HS). HS accumulation in the brain causes severe central nervous system (CNS) complications, including learning and memory deficits and seizure. MPS IIIA patients have short life expectancies and there currently is no cure for the disease. This thesis work was aimed at identifying an early neurological phenotype in the mouse model of MPS IIIA. The data will aid in the design of an …

Use Of Anti-Mullerian Hormone To Select For Fertility In Beef Heifers, Hannah Newberry

Animal Science Undergraduate Honors Theses

ABSTRACT

A study was conducted to determine whether concentration of serum Anti-Mullerian Hormone (AMH) at weaning and/or breeding could predict subsequent fertility in beef heifers. Frequency distribution was used to assign serum AMH concentration measured at weaning, breeding, and the change from weaning to breeding, into quartiles. Comparison of heifers based on serum AMH quartiles at weaning failed (P ³ 0.35) to detect any effect of AMH on subsequent heifer cyclicity at breeding, estrous response after synchronization, artificial insemination (AI) pregnancy rate, overall breeding season pregnancy rate, or estimated estrous cycle of the breeding season when conception occurred. Based on …

Permian Scorpions From The Petrified Forest Of Chemnitz, Germany, Jason A. Dunlop, David A. Legg, Paul L. Selden, Victor Fet, Joerg W. Schneider, Ronny Rößler

Background: Paleozoic scorpions (Arachnida: Scorpiones) have been widely documented from the Carboniferous Period; which hosts a remarkable assemblage of more than sixty species including both putative stem- and crown-group fossils. By contrast the succeeding Permian Period is almost completely devoid of records, which are currently restricted to a trace fossil from the early Permian of New Mexico, USA and some limb fragments from the late Permian of the Vologda Region, Russia.

Results: ?Opsieobuthus tungeri sp. nov. from the Petrified Forest of Chemnitz, Germany represents the first complete body fossils of scorpions from the Permian. Explosive volcanism preserved these remarkable …

Host-Parasite Associations Of Small Mammal Communities And Implications For The Spread Of Lyme Disease, Matthew J. Buchholz

Masters Theses & Specialist Projects

Many zoonotic pathogens of concern to human and veterinary health are maintained in the environment within small mammal reservoirs and vectored to new hosts by ectoparasitic arthropods. While the ecological relationships among small mammals, ectoparasites, and disease-causing symbiotic microorganisms are important to these dynamics, little is known about them across much of North America. The sylvatic cycle of Borrelia burgdorferi, the etiologic agent of Lyme disease, is of particular interest because Lyme disease is the most common vector-borne disease of humans in the United States. However, cases of Lyme disease are primarily confined to the northeastern and Midwestern United States, …

Mother--Offspring Recognition Via Contact Calls In Cattle, Bos Taurus, Mónica Padilla De La Torre, Elodie F. Briefer, Brad M. Ochocki, Alan G. Mcelligott, Tom Reader

Sentience Collection

Individual recognition in gregarious species is fundamental in order to avoid misdirected parental investment. In ungulates, two very different parental care strategies have been identified: ‘hider’ offspring usually lie concealed in vegetation whereas offspring of ‘follower’ species remain with their mothers while they forage. These two strategies have been suggested to impact on mother--offspring vocal recognition, with unidirectional recognition of the mother by offspring occurring in hiders and bidirectional recognition in followers. In domestic cattle, Bos taurus, a facultative hider species, vocal communication and recognition have not been studied in detail under free-ranging conditions, where cows and calves can graze …

How Microbial Communities Differ In Ruminants On A Glycerin Vs Common Diet, Makala Muller, Nirosh D. Aluthge, Allison L. Knoell, Morgan Kaiser, Samodha C. Fernando

UCARE: Research Products

Can we reduce methane by using dietary interventions to reduce carbon footprint and increase feed efficiency? Ruminant livestock account for a significant amount of the anthropogenic methane produced in the U.S. All ruminant livestock produce 28% of the earth’s methane emissions. The methane within ruminants is produced by a microbial fermentation, especially by a group of bacteria known as the methanogens. However, the different species of methanogens and their pathways of methane production within ruminants are not fully understood. Cattle are considered one of the main producers of methane. They produce 20% of the U.S. methane emissions. Methane absorbs more …

Examining Maternal Obesity Effects On Oogenesis, Follicular Development, And Embryonic Myogenesis, Chris Lindeman, Jennifer Wood

UCARE: Research Products

The CDC estimates that more than one-third of U.S. adults (approximately 78.6 million) are obese. Despite national efforts to combat this with diet and exercise, the number of obese adults and children continues to climb. It is critical to emphasize that obesity can lead to lifelong, chronic complications and health risks including hypertension, heart disease, and diabetes.

Diet and obesity also have important impacts on the reproductive health of female including the ability to become pregnant (fertility) and risk for complications during pregnancy. Furthermore, for women who do become pregnant, obesity can affect the development of the embryo and fetus, …

The Effects Of Androgens On Bovine And Human Granulosa Cells, Katelyn C. Griger, Sarah Romereim, Renata Spuri-Gomes, Mohamed A. Abedal-Majed, Mariah Hart, Scott G. Kurz, Robert A. Cushman, John S. Davis, Jennifer R. Wood, Andrea S. Cupp

UCARE: Research Products

A subpopulation of cows in the Physiology herd has been identified as subfertile due to sporadic or chronic anovulation. This decrease in fertility could be lost profits for farmers and raises questions about ovulation disorders in women. Granulosa cells, a type of cell that is essential to ovarian follicle development, was investigated to determine if high concentrations of a hormone, androstenedione, could impact the follicular environment enough to cause anovulation disorders. Previous studies suggested that excess androgen may decrease the number of functioning granulosa cells by preventing them from proliferating within the follicle. Fewer granulosa cells mean fewer cells that …

Diversity-Dependent Cladogenesis Throughout Western Mexico: Evolutionary Biogeography Of Rattlesnakes (Viperidae: Crotalinae: Crotalus And Sistrurus), Christopher Blair, Santiago Sánchez-Ramírez

Publications and Research

Rattlesnakes (Crotalus and Sistrurus) represent a radiation of approximately 42 species distributed throughout the New World from southern Canada to Argentina. Interest in this enigmatic group of snakes continues to accrue due, in part, to their ecomorphological diversity, contributions to global envenomations, and potential medicinal importance. Although the group has garnered substantial attention from systematists and evolutionary biologists for decades, little is still known regarding patterns of lineage diversification. In addition, few studies have statistically quantified broad-scale biogeographic patterns in rattlesnakes to ascertain how dispersal occurred throughout the New World, particularly among the different major biomes of the …

Acropora Habitat Evaluation And Restoration Site Selection Using A Species Distribution Modeling Approach, Katherine Wirt Ames

USF Tampa Graduate Theses and Dissertations

While populations of nearly all stony coral species along the Florida reef tract have exhibited decline, the most notable decline has occurred in the once-dominant acroporid species (Acropora cervicornis, A. palmata). Both species were listed in 2006 as threatened under the Endangered Species Act. This listing, combined with their continued decline, has resulted in large-scale restoration efforts throughout Florida and the Western Caribbean. Currently, there is little to no information regarding spatial prioritization of sites for these restoration efforts. The primary objective of this dissertation was to utilize species distribution modeling, informed by existing data from the …

Use Of The Mitochondrial Control Region As A Potential Dna Mini-Barcoding Target For The Identification Of Canned Tuna Species, Jacquelyn K. Mitchell, Rosalee S. Hellberg

Food Science Faculty Articles and Research

In this study, a DNA mini-barcoding methodology was developed for the differentiation of species commonly found in canned tuna. Primers were designed to target a 236-base pair (bp) fragment of the mitochondrial control region (CR) and a 179-bp fragment of the first internal transcribed spacer region (ITS1). Phylogenetic analysis revealed the ability to differentiate 13 tuna species on the basis of the CR mini-barcode, except in a few cases of species introgression. Supplementary use of ITS1 allowed for differentiation of introgressed Atlantic bluefin tuna (Thunnus thynnus) and albacore tuna (Thunnus alalunga), while differentiation of introgressed Atlantic …

Circulating Amino Acids In Blood Plasma During The Peripartal Period In Dairy Cows With Different Liver Functionality Index, Z. Zhou, J. J. Loor, F. Piccioli-Cappelli, F. Librandi, G. E. Lobley, E. Trevisi

Physiology Collection

The liver functionality index (LFI) measures the changes of albumin, cholesterol, and bilirubin concentrations between 3 and 28 d postpartum. This composite index, based on variables with direct relevance to liver-specific plasma protein synthesis (albumin), hepatic/intestinal lipoprotein synthesis (cholesterol), and clearance of breakdown products of heme catabolism (bilirubin), provides a tool for evaluating manifestations of hepatic disease. Both energy and protein metabolism are likely to be affected by various physiological challenges in this period but have not been tested systematically. The present study was conducted to profile AA in cows with high or low LFI during the peripartal period …
