Shape Evolution And Sexual Dimorphism In The Mandible Of The Dire Wolf, Canis Dirus, At Rancho La Brea, Alexandria L. Brannick
Shape Evolution And Sexual Dimorphism In The Mandible Of The Dire Wolf, Canis Dirus, At Rancho La Brea, Alexandria L. Brannick
Theses, Dissertations and Capstones
The Rancho La Brea tar pits are a classic fossil lagerstätten, famous for the deposition of episodic accumulations of large numbers of fossils over short intervals in the late Pleistocene. I analyzed 157 Canis dirus (dire wolf) hemi-mandibles from Rancho La Brea through a 2D landmark-based morphometric analysis to test for size and shape changes through time. I scored 16 landmarks on each mandible gathered from four pits of different ages: 61/67 (~13-14 thousand years ago [ka]), 13 (~17-18 ka), 2051 (~26 ka), and 91 (~28 ka). Analyses indicate size does change through time, and shares a broad correlation with …
Subthreshold Toxic Effects Of Atrazine And Three Degradates On Behavior In Procambarus Clarkii, Carol B. Starkey
Subthreshold Toxic Effects Of Atrazine And Three Degradates On Behavior In Procambarus Clarkii, Carol B. Starkey
Theses, Dissertations and Capstones
Atrazine is among the most heavily applied pesticides worldwide, and recent evidence suggests that it may be unsafe at environmental levels. It is a known endocrine disruptor and a suggested neurotoxin. The US EPA Maximum Contaminant Level (MCL) is 3 μg/L for human ingestion and 200 μg/L for limited human exposure. Several environmentally persistent degradates have been identified, including deethylatrazine (DEA), deisopropylatrazine (DIA) and hydroxyatrazine (HA). No MCLs have been established for these degradates, although some are suggested toxins. Thus, there remains concern for the risk associated with the presence of atrazine and its degradates in the environment. Currently little …
Examining The Effects Of Liming On Gyrinophilus Porphyriticus With A Comparison Of Multiple Sampling Methods, Elise Marie Edwards
Examining The Effects Of Liming On Gyrinophilus Porphyriticus With A Comparison Of Multiple Sampling Methods, Elise Marie Edwards
Theses, Dissertations and Capstones
Environmental acidification is affecting stream-associated species around the globe. As a result, different management strategies have been implemented to deal with acidification resulting from acid rain and acid mine drainage. Adding limestone to streams attempts to reverse the effects of acidification. While liming increases the pH of many acidic environments, studies involving the effects of liming on different animal species have shown mixed results. In this study, I examined the effects of liming on Gyrinophilus porphyriticus (the Spring Salamander) abundance and I also determined the best method of detection for G. porphyriticus. From June 10th to September 1st 2013, I …
Using Ailuropoda Melanoleuca As A Model Species For Studying The Ecomorphology Of Paranthropus, Ryan Andrew King
Using Ailuropoda Melanoleuca As A Model Species For Studying The Ecomorphology Of Paranthropus, Ryan Andrew King
Theses, Dissertations and Capstones
Giant pandas (Ailuropoda melanoleuca) have cranial morphology similar to the extinct hominin genus Paranthropus which makes them an excellent model species when studying Paranthropus diet. Both species have wide skulls with flared zygomatic arches adapted for chewing. To gain insight into possible food sources of Paranthropus, I investigated the giant panda’s specialized diet of bamboo. The toughness, hardness, and stiffness of various bamboo species was determined to assess mechanical challenges facing giant pandas during feeding. Bamboo is thought to be tough, but studies on such properties and how they apply to mastication of giant pandas are largely …
The Natural Life History Of Cambarus (Puncticambarus) Smilax, The Greenbrier Crayfish, Paul William Hughes
The Natural Life History Of Cambarus (Puncticambarus) Smilax, The Greenbrier Crayfish, Paul William Hughes
Theses, Dissertations and Capstones
The natural life history of Cambarus (Puncticambarus) smilax, the Greenbrier Crayfish, was studied in West Fork of the Greenbrier River and in Thorny Creek, a tributary of the main stem of the Greenbrier River. The Greenbrier Crayfish gets its name from the Greenbrier River watershed where it is thought to occur exclusively. Among described members of the subgenus Puncticambarus, C. smilax is a sister taxon most similar to Cambarus (Puncticambarus) robustus. Monthly collections were made within the two study sites, from August 2010 to July 2011. Collecting techniques included dip-netting, seine-netting, and hand collecting. Cambarus smilax and all other species …

Horses As Sources Of Proprietary Information: Commercialization, Conservation, And Compensation Pursuant To The Convention On Biological Diversity, Haley Mcclory, Stanley Kowalski
Horses As Sources Of Proprietary Information: Commercialization, Conservation, And Compensation Pursuant To The Convention On Biological Diversity, Haley Mcclory, Stanley Kowalski
Law Faculty Scholarship
Horses indigenous to East and Southeast (E/SE) Asia, including native, landrace, feral, and wild populations, embody valuable genetic diversity. Conservation efforts for animals have largely been driven by humane altruism, with little consideration for the information value of genomes. Yet, if horses are viewed as archives of information as well as objects of affection, their conservation shifts to a market-based paradigm. Horse genetic resources (GR) likely contain significant value to the lucrative global horse industry, including veterinary applications such as diagnostics, therapeutics, genetic markers, gene therapies, and cloning technologies. As biotechnology becomes increasingly sophisticated, mining of horse GR will accelerate, …

Reduction Of The Pectoral Spine And Girdle In Domesticated Channel Catfish Is Likely Caused By Changes In Selection Pressure, Michael L. Fine
Reduction Of The Pectoral Spine And Girdle In Domesticated Channel Catfish Is Likely Caused By Changes In Selection Pressure, Michael L. Fine
Biology Publications
Locked pectoral spines of the Channel Catfish Ictalurus punctatus more than double the fish's width and complicate ingestion by gape-limited predators. The spine mates with the pectoral girdle, a robust structure that anchors the spine. This study demonstrates that both spine and girdle exhibit negative allometric growth and that pectoral spines and girdles are lighter in domesticated than in wild Channel Catfish. This finding could be explained by changes in selection pressure for spine growth during domestication or by an epigenetic effect in which exposure to predators in wild fish stimulates pectoral growth. We tested the epigenetic hypothesis by exposing …
As The Egg Turns: Monitoring Egg Attendance Behavior In Wild Birds Using Novel Data Logging Technology, Scott A. Shaffer, Corey Clatterbuck, Emma Kelsey, Alex Naiman, Lindsay Young, Eric Vanderwerf, Pete Warzybok, Russell Bradley, Jaime Jahncke, Geoff Bower
As The Egg Turns: Monitoring Egg Attendance Behavior In Wild Birds Using Novel Data Logging Technology, Scott A. Shaffer, Corey Clatterbuck, Emma Kelsey, Alex Naiman, Lindsay Young, Eric Vanderwerf, Pete Warzybok, Russell Bradley, Jaime Jahncke, Geoff Bower
Faculty Publications, Biological Sciences
Egg turning is unique to birds and critical for embryonic development in most avian species. Technology that can measure changes in egg orientation and temperature at fine temporal scales (1 Hz) was neither readily available nor small enough to fit into artificial eggs until recently. Here we show the utility of novel miniature data loggers equipped with 3-axis (i.e., triaxial) accelerometers, magnetometers, and a temperature thermistor to study egg turning behavior in free-ranging birds. Artificial eggs containing egg loggers were deployed in the nests of three seabird species for 1–7 days of continuous monitoring. These species (1) turned their eggs …
Natural History Of A Population Of Wood Turtles (Glyptemys Insculpta) In West Virginia, Jessica Curtis
Natural History Of A Population Of Wood Turtles (Glyptemys Insculpta) In West Virginia, Jessica Curtis
Theses, Dissertations and Capstones
The Wood Turtle (Glyptemys insculpta) is listed as vulnerable in West Virginia and only occurs in the Eastern Panhandle. The study population is unique in West Virginia because it occurs at a much higher mean elevation than other Wood Turtle populations in the state. The primary objective of this study was to determine if, and to what extent, altitude affected this population’s ecology. Turtles were located with opportunistic surveys and captured by hand. I located 31 turtles: 18 males, and 13 females. Turtles were captured a total of 68 times. Ratio of males to females did not differ significantly from …
Empathy In Other Apes, Kristin Andrews, Lori Gruen
Empathy In Other Apes, Kristin Andrews, Lori Gruen
Sentience Collection
A number of scholars have offered behavioral and physiological arguments in favor of the existence of empathy in other species (see Bekoff & Pierce 2009, Flack & de Waal 2000, Plutchik 1987). While the evidence is compelling, claims about empathy in nonhuman apes face two different challenges. The first challenge comes from a set of empirical findings that suggest great apes are not able to think about other’s beliefs. The argument here is based on a view that empathy is associated with folk psychological understanding of others’ mental states, or mindreading, and the existence of mindreading among the other apes …

What Do Zebrafish Want? Impact Of Social Grouping, Dominance And Gender On Preference For Enrichment, Paul Schroeder, Soffia Jones, Iain S. Young, Lynne U. Sneddon
Sentience Collection
Although environmental enrichment is known to improve laboratory rodent wellbeing and enhance scientific data collection, relatively little is known with regards to the type of enrichment that might be useful for zebrafish (Danio rerio). Therefore, this study explored if zebrafish displayed preferences for a range of enrichments, including substrates, artificial plants, combinations thereof and airstones. Tanks divided into two compartments containing different enrichment cues were used to determine the preferences of zebrafish housed in pairs and groups of eight. When comparing time spent in enriched versus barren compartments, dominant individuals in a pair displayed a preference for substrate and behaviourally …
Effect Of Confinement On Water-Borne And Whole Body Cortisol In Wild And Captive-Eared Rainbowfish (Melanoteania Duboulayi), Amina Zuberi, Culum Brown, Sinan Ali
Effect Of Confinement On Water-Borne And Whole Body Cortisol In Wild And Captive-Eared Rainbowfish (Melanoteania Duboulayi), Amina Zuberi, Culum Brown, Sinan Ali
Physiology Collection
Whole body and water-borne cortisol levels were measured in captive reared and wild Rainbowfish (Melanoteania duboulayi Castelnau 1878) subjected to social isolation by confining them in a beaker for 30 min to induce an acute stress response. Wild fish had higher levels of cortisol before and after exposure to a mild stressor and also showed the greatest stress response. The differences in stress responses are likely the result of artificial selection in the captive environment. Importantly, there was a strong linear relationship between whole body and water-borne cortisol in wild and captive reared populations (r2 =0. 95 and 0.84, …
