Tracking Canada Geese Near Airports: Using Spatial Data To Better Inform Management, Ryan J. Askren, Brett E. Dorak, Heath M. Hagy, Michael W. Eiccholz, Brian E. Washburn, Michael P. Ward

Human–Wildlife Interactions

The adaptation of birds to urban environments has created direct hazards to air transportation with the potential for catastrophic incidents. Bird–aircraft collisions involving Canada geese (Branta canadensis; goose) pose greater risks to aircraft than many bird species due to their size and flocking behavior. However, information on factors driving movements of geese near airports and within aircraft arrival/departure areas for application to management are limited. To address this need, we deployed 31 neck collar-mounted global positioning system transmitters on Canada geese near Midway International Airport in Chicago, Illinois, USA during November 2015 to February 2016. We used the …

Train–Elephant Collisions In A Biodiversity-Rich Landscape: A Case Study From Rajaji National Park, North India, Ritesh Joshi, Kanchan Puri Jan 2019

Train–Elephant Collisions In A Biodiversity-Rich Landscape: A Case Study From Rajaji National Park, North India, Ritesh Joshi, Kanchan Puri

Human–Wildlife Interactions

Linear developments like railways and highways have a negative impact on ecological processes of wildlife species at a landscape level. The impacts in terms of wildlife mortality and threat to surviving populations of species have been well-studied; however, less work has been done to understand the potential causes of train–wildlife collisions, particularly large mega-fauna such as Asian elephants (Elephas maximus; elephant). In this case study, we review train–elephant collisions (TECs) that occurred in Rajaji National Park (RNP) and discuss some potential causes of TECs along with mitigation measures. The RNP, located in the upper Gangetic plains of northern …


Temporal Variation Of Moose–Vehicle Collisions In Alaska, Lucian R. Mcdonald, Terry A. Messmer, Michael R. Guttery Jan 2019

Temporal Variation Of Moose–Vehicle Collisions In Alaska, Lucian R. Mcdonald, Terry A. Messmer, Michael R. Guttery

Human–Wildlife Interactions

Collisions between vehicles and wildlife have long been recognized to pose threats to motorists and wildlife populations. In addition to the risk of injury or mortality faced by the motorists involved in wildlife-vehicle collisions (WVCs), other drivers are also put at risk due to road obstructions and traffic congestions associated with WVCs. Most WVCs in Alaska involve moose (Alces alces), an animal that is sufficiently large to pose a threat to property and human life when involved in collisions. We analyzed the temporal variation in the number of moose–vehicle collisions (MVCs) reported in the 4 most populous boroughs …


Cost–Benefit Analysis Of Coyote Removal As A Management Option In Texas Cattle Ranching, R. Kyle Brewster, Scott E. Henke, Benjamin L. Turner, John M. Tomeček, Alfonso Ortega-S. Jan 2019

Cost–Benefit Analysis Of Coyote Removal As A Management Option In Texas Cattle Ranching, R. Kyle Brewster, Scott E. Henke, Benjamin L. Turner, John M. Tomeček, Alfonso Ortega-S.

Human–Wildlife Interactions

The monetary value of livestock losses attributed to coyote (Canis latrans) predation in North America has increased during the past 20 years. In Texas, USA alone in 2011, these loses were estimated at $6.9 million. To mitigate coyote-related livestock losses, several lethal and nonlethal control methods have been developed. However, there remains a need for better information to guide management decisions regarding cost-effective predator control strategies for livestock production systems. We acquired data, which was used in the model, from published literature from 1960 to present day, subject matter experts, and anecdotal information on coyote ecology. We developed …


Wildlife Damage To Crops Adjacent To A Protected Area In Southeastern Mexico: Farmers’ Perceptions Versus Actual Impact, Gabriel Can-Hernández, Claudia Villanueva-García, Elías José Gordillo-Chávez, Coral Jazvel Pacheco-Figueroa, Elizabeth Pérez-Netzahual, Rodrigo García-Morales Jan 2019

Wildlife Damage To Crops Adjacent To A Protected Area In Southeastern Mexico: Farmers’ Perceptions Versus Actual Impact, Gabriel Can-Hernández, Claudia Villanueva-García, Elías José Gordillo-Chávez, Coral Jazvel Pacheco-Figueroa, Elizabeth Pérez-Netzahual, Rodrigo García-Morales

Human–Wildlife Interactions

Human–wildlife conflicts occur when wildlife has an adverse effect on human activities (e.g., predation of livestock, crop raiding). These conflicts are increasing, particularly in areas surrounding natural protected areas, where villagers engage in subsistence agriculture. Crop damage may cause farmers to retaliate and harm wildlife species considered responsible for the damage. Among the factors that determine the intensity of the conflict are the frequency of the damage and the amount of biomass consumed relative to the perceptions, values, and cultural history of the farmers affected. To better understand the conflicts between farmers and wildlife, we compared farmer perceptions of wildlife …

On Neglected Taxa: Protostomes And The Evolution Of Myelination, Michaella P. Andrade, Charles Morphy D. Santos Jan 2019

On Neglected Taxa: Protostomes And The Evolution Of Myelination, Michaella P. Andrade, Charles Morphy D. Santos

Animal Sentience

Understanding the evolution of nervous and sensory systems in animals is key to understanding the distribution of animal sentience. However, the use of model organisms – mostly vertebrates, and especially mammals – often biases comparative analyses. Sneddon et al. (2018a,b) point out that using nonhuman animals as models helps us better understand the multifaceted aspects of animal pain and sentience. Several concerns need to be considered in dealing with model organisms. Here we discuss how models that are unrepresentative phylogenetically influence hypotheses about the evolution of the myelination in animals. Greater effort is needed to escape “vertebrate-centrism” in evolutionary research.


A Bioinfomatic Analysis Of Luminal And Mucosal Ileal Bacteria Colonizing Nursery Pigs Fed Different Protein Sources, Jamie L. Ortman Jan 2019

A Bioinfomatic Analysis Of Luminal And Mucosal Ileal Bacteria Colonizing Nursery Pigs Fed Different Protein Sources, Jamie L. Ortman

Electronic Theses and Dissertations

Weaning is a critical time in a young pig’s life that will greatly impact its adult growth and development. The objective of this research was to evaluate the effects of various protein sources on the bacterial composition within luminal and mucosal populations in simple and complex diets to gain a better understanding of factors influencing gut health. Weaned pigs were fed 1 of 3 simple experimental diets: 1) basic diet containing corn and soybean meal (Negative Control - NEG), 2) basic diet + fishmeal (FM; Positive Control - POS), and 3) basic diet + microbially-enhanced soybean meal (MSBM). Phase I …


Evaluating Spatial Distributions Of Scent-Marks In Semi-Free-Ranging Groups Of Lemur Catta At The Duke Lemur Center, Shallu Prasher Jan 2019

Evaluating Spatial Distributions Of Scent-Marks In Semi-Free-Ranging Groups Of Lemur Catta At The Duke Lemur Center, Shallu Prasher

Graduate Research Theses & Dissertations

Scent-marking is a widespread form of olfactory signaling exhibited in mammals and for a select group of primates. Although research exists on the process of scent-marking, surface preferences, and for the function of scent-marking in lemurs, analyses of how lemur group scent-marking distributions map onto their home range are lacking. The endangered ring-tailed lemur (Lemur catta) deposits scent-marks using its ano-genital, chest, and wrist glands. This project was designed to collect data on two groups of semi-free-ranging captive ring-tailed lemurs at the Duke Lemur Center to first assess how scent-marks are distributed within their home ranges; and second, to evaluate …

Identification And Expression Of Dmrt1 And Sox9 During The Gonadal Differentiation Of Rana Chensinensis, Xin-Yi Li, Wen-Jie Jin, Lei Lei, Yuhui Zhang Jan 2019

Identification And Expression Of Dmrt1 And Sox9 During The Gonadal Differentiation Of Rana Chensinensis, Xin-Yi Li, Wen-Jie Jin, Lei Lei, Yuhui Zhang

Turkish Journal of Zoology

Gonadal sex differentiation proceeds by the interplay of various genes including the transcription factors and secretory factors in a complex network. Dmrt1 and Sox9 were considered to be the essential genes involved in the testicular differentiation in mammals, birds, reptiles, and fishes. Here, we have successfully isolated and characterized cDNAs encoding the Rana chensinensis orthologs of Dmrt1 and Sox9, and we have determined patterns of expression during gonadal differentiation and adult tissues. At the molecular level, a clear sexual dimorphism of rcDmrt1 and rcSox9 was observed in the gonad-mesonephros complex or gonads of tadpoles during stages 26-46. The rcDmrt1 transcript …


Spatiotemporal Distribution And Population Structure Of Clibanarius Symmetricus (Randall, 1840) (Crustacea, Diogenidae) In An Amazon Estuary, Ana Carolina Melo Rodrigues, Jussara Moretto Martinelli-Lemos Jan 2019

Spatiotemporal Distribution And Population Structure Of Clibanarius Symmetricus (Randall, 1840) (Crustacea, Diogenidae) In An Amazon Estuary, Ana Carolina Melo Rodrigues, Jussara Moretto Martinelli-Lemos

Turkish Journal of Zoology

Rocky outcrops in the intertidal zones of estuaries often contain a highly diverse microbenthic community which includes the hermit crab, Clibanarius symmetricus, an abundant species on the equatorial Amazon coast. However, the ecology of this anomuran is poorly understood. Given this, the present study investigated the spatiotemporal distribution and structure of the C. symmetricus populations that inhabit the rocky outcrops of the Marapanim estuary in northern Brazil. Samples were collected monthly over a yearly cycle covering both the dry and rainy seasons in the upper and lower midlittoral zones during low tide. The distribution and abundance of C. symmetricus were …


Application Of Multifactorial Discriminant Analysis In The Morphostructural Differentiation Of Wild And Cultured Populations Of Vieja Azul (Andinoacara Rivulatus), Johanna Caez, Ana Gonzalez, Martin A. Gonzalez, Elena Angon, Jorge M. Rodriguez, Francisco Peña, Cecilio Barba, Antón García Jan 2019

Application Of Multifactorial Discriminant Analysis In The Morphostructural Differentiation Of Wild And Cultured Populations Of Vieja Azul (Andinoacara Rivulatus), Johanna Caez, Ana Gonzalez, Martin A. Gonzalez, Elena Angon, Jorge M. Rodriguez, Francisco Peña, Cecilio Barba, Antón García

Turkish Journal of Zoology

To better determine the ecological variation (body shape and structure) of the Vieja Azul (Andinoacara rivulatus; syn.: Aequidens rivulatus) in northwest Ecuador (Los Ríos Province), 300 specimens of both sexes (150 male and 150 female) were collected from 3 different locations, one from a wild production system and two from fish farm populations in the Quevedo River. Twelve meristic, 26 traditional morphometric, and 32 truss measurements, among 25 anatomical landmarks, were determined. The body weight (BW), total length (TL), eye diameter (ED), dorsal fin ray length (DFRL), and body perimeter 3 (P3) showed significant differences (P < 0.05) between production systems, and sex had significant influence on preanal length (Pre-AL), P3, and body width 2 (LC2). Females showed higher mean values than males in all measurements, except for BW. The Fulton factor differed for both factors considered. The canonical discriminant analysis revealed a percentage of correct assignment of 64.42% for the dataset, 85% and 60.9% for cultured and wild females, and 62.1% and 56.3% for wild and cultured males, respectively, as well as morphometric variation between groups. Results could be attributed to environmental conditions (habitat, temperature, and food). The Mahalanobis test showed greater distances among females than among males. In conclusion, this study provides valuable morphological information on the shape and structure of Andinoacara rivulatus that can be used to characterize and quantify the changes that occur as a consequence of adaptation to a different habitat. The authors hope that the information obtained from the present study will be helpful for fisheries, biologists, and taxonomists.


Induction Of Abnormal Sperm Heads In Small Mammals Under Chronic Ionizing Radiation, Lyudmila Bashlykova, Oksana Raskosha, Natalia Starobor Jan 2019

Induction Of Abnormal Sperm Heads In Small Mammals Under Chronic Ionizing Radiation, Lyudmila Bashlykova, Oksana Raskosha, Natalia Starobor

Turkish Journal of Zoology

The results of this study show a mutagenic effect of low-dose ionizing radiation in male germ cells. The damage of male germ cells was assessed by the frequency of abnormal sperm heads in tundra voles (Microtus oeconomus Pall.), bank voles (Myodes glareolus Schreb.), and field mice (Apodemus agrarius Pall.) from the 30 km exclusion zone around the Chernobyl nuclear power station and for laboratory animals (mice and rats) under chronic γ-irradiation. The abnormal sperm head detection method used appeared to be sensitive to conditions of low-dose irradiation and can consequently be recommended as a bioindicator to monitor environmental radiation pollution.


Hardly Habitual: Chimpanzees And Gorillas Show Flexibility In Their Motor Responses When Presented With A Causally-Clear Task, Sarah L. Jacobson, Lydia M. Hopper Jan 2019

Hardly Habitual: Chimpanzees And Gorillas Show Flexibility In Their Motor Responses When Presented With A Causally-Clear Task, Sarah L. Jacobson, Lydia M. Hopper

Publications and Research

In contrast to reports of wild primates, studies of captive primates' flexibility often reveal conservatism: individuals are unable to switch to new and more efficient strategies when task demands change. We propose that such conservatism might be a result of task design and hypothesize that conservatism might be linked to primates' lack of causal understanding in relation to experimental apparatuses. We investigated if chimpanzees (Pan troglodytes) and western lowland gorillas (Gorilla gorilla gorilla) would show greater flexibility when presented with a causally-clear task. We presented six chimpanzees and seven gorillas with a clear tube from which …

An Assessment Of Night Time And Seasonal Electrofishing In The Lower Wabash River, Eric Christopher Hine Jan 2019

An Assessment Of Night Time And Seasonal Electrofishing In The Lower Wabash River, Eric Christopher Hine

Masters Theses

Large rivers are highly important systems; being exploited both commercially and recreationally. Because of this usage by humans, close monitoring of the ecology of theses rivers is of the utmost importance. The Long-Term Electrofishing project (LTEF) monitors the fish communities of the Illinois, Mississippi, Wabash, and Ohio rivers using day time, pulsed-DC electrofishing during the late Spring through the early Fall each year. Given that previous studies have noted diel and seasonal changes in catch and composition of fish communities, the addition of night time electrofishing may be beneficial to the overarching goals of the LTEF. This study sought to …


Evaluating Methods Of Obtaining Male Pheromone From Hymenochirus Sp. Using Analytical Chemistry, Vincent Wing-Kun Leung Jan 2019

Evaluating Methods Of Obtaining Male Pheromone From Hymenochirus Sp. Using Analytical Chemistry, Vincent Wing-Kun Leung

University of the Pacific Theses and Dissertations

Male Hymenochirus sp. frogs are known to release pheromone that attracts females of the same species. Four methods for collecting secretions containing pheromone in Hymenochirus sp. were tested: norepinephrine injection, gonadotropin-releasing hormone injection, homogenization of gland tissue, and electrostimulation of the skin over the breeding gland area. The samples collected were analyzed using high-performance liquid chromatography (HPLC) and mass spectrometry. The HPLC chromatograph for the male norepinephrine sample contained a peak at 6.4 min that was not in the female norepinephrine sample HPLC chromatograph. The male norepinephrine sample mass spectrum had a peak of m/z 292.0 not in the female …


Why Are Sheep Sheepish? How Perception Affects Animal Stereotyping, Robert G. Franklin Jr. Jan 2019

Why Are Sheep Sheepish? How Perception Affects Animal Stereotyping, Robert G. Franklin Jr.

Animal Sentience

Marino & Merskin present compelling evidence that many stereotypes of sheep are incorrect. One factor that may play an important role in animal stereotyping is the physical appearance of animals, which can directly lead to stereotyping through automatic mental processes. Sheep have a round and babyish appearance that directly evokes judgments of warmth and docility. Depictions of sheep in art, and especially cartoons, reinforce this stereotype.


Attainment And Maintenance Of Pubertal Cyclicity May Predict High A4 Cows With Reduced Fertility, Sarah Nafziger Jan 2019

Attainment And Maintenance Of Pubertal Cyclicity May Predict High A4 Cows With Reduced Fertility, Sarah Nafziger

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

Puberty attainment was investigated in heifers. Blood samples were collected from weaning until breeding during 6 years from heifers born in 2012-2017. Plasma progesterone concentrations ≥ 1 ng/ml were used to indicate cyclicity, and heifers were categorized into one of four puberty groups using SAS: 1) Early heifers reached puberty before March 12 and cycled continuously during the sampling period, 2) Typical heifers reached puberty on or after March 12 and cycled continuously, 3) Start-Stop heifers had at least one occurrence of progesterone ≥ 1 ng/ml but discontinued cycling during the sampling period, and 4) Non-Cycling heifers had no occurrence …

Turkish Journal of Veterinary & Animal Sciences

The reproductive biology of the domestic dog is unique among mammalian species; because of this, in vitro maturation (IVM) rate is still very low compared with other domestic animals in spite of attempts at improvement. The aim of this study was to consider the use of recombinant human gonadotropins as a replacement for pituitary gonadotropins for IVM of dog oocytes. A total of 845 cumulus-oocyte complexes were used in this study. To determine the effects of human recombinant gonadotropins, maturation medium was supplemented with two different concentrations (0.05 or 0.1 IU/mL) of pituitary (pFSH, pLH) and human recombinant (rhFSH and …
