Extirpation Risk of the Endangered Golden Langur (<i>Trachypithecus geei</i>) Inside and Outside Biological Corridors, Langthel Sub-district, Trongsa, Central District Bhutan
<p>I assessed extirpation risks of the golden langur (<em>Trachypithecus geei</em>) in two landscapes (inside and outside the biological corridor). Working with a team of trained scientists, I collected data on group size, feeding range, sleeping sites, and predation on golden langurs from Langthel …

"The ""Popol Vuh"" and the Dominican Friar Francisco Ximenez: The Maya -Quiche Narrative as a Product of Religious Extirpation in Colonial Highland Guatemala"
My dissertation provides an inter-disciplinary, revisionist approach to the Popol Vuh that encompasses the fields of literature and anthropology. I challenge traditional approaches to this manuscript by placing it within the historical, cultural, and religious context of colonial contact. My study …

A population dynamic model assessing options for managing eastern oysters (Crassostrea virginica) and triploid Suminoe oysters (Crassostrea ariakensis) in Chesapeake Bay
… and their likely effects on the probability of extirpation of local eastern oyster (Crassostrea virginica) populations in the Chesapeake Bay. Management strategies include varying the minimum shell length-at-harvest, harvest rate, and rate and frequency of stocking of oyster seed with respect to …

Geochemical and Taphonomic Signatures of Freshwater Mussel Shells as Evidence of Mercury-Related Extirpations in the North Fork Holston River, Virginia
… River, an aquatic habitat affected by extensive extirpations of mussel populations starting in the early 1970's. Mussel shells (n=366) collected from 5 sites, upstream and downstream of Saltville (where mercury was used from 1950-1972) were analyzed to test if: (1) geochemical signatures of …

Conservation Genetics and Distribution of the Yazoo Darter (Etheostoma Raneyi)
… range and that the species is at greater risk of extirpation due to anthropogenic disturbance in the Yocona River drainage. Most genetic variation is partitioned among populations and each tributary of the two major river drainages that we sampled constituted a genetically distinct population. …

Decline of the Savannah River Redeye Bass (Micropterus Coosae) Due to Introgressive Hybridization With Invasive Alabama Spotted Bass (Micropterus Punctulatus Henshalli)
… introductions of invasives can lead to the extirpation or extinction of native species through a myriad of different biological mechanisms. Introgressive hybridization is one mechanism that is often overlooked due to difficulty of examination without the use of molecular techniques. However, …

Platonic and Stoic Passions in Philo of Alexandria
… in condemning the passions and championing their extirpation, he is <br/>unique, even among the Stoics, in the extent and degree to which he emphasized their blameworthiness. Chapters three and four examine Philo's Stoicizing treatment of the tripartite and bipartite Platonic elements in his …

Examination of the Effects of Pinealectomy upon Adrenal Structure in the White Rat
The effects of pineal extirpation at three days and thirty days upon adrenal structure in male and female rats were examined. Animals were either reared in a diurnally lighted (12 : 12) environment or in total darkness; those pinealectomized at three days were sacrificed at either twenty or forty …

Seasonal dietary composition of the eastern coyote (Canis latrans) on the berry college campus in Northwestern Georgia
… colonized eastern North America following wolf extirpation and the clearing of forested landscapes. The coyote has expanded its geographic range into Georgia during the past 50 years, and its impact as the top predator is potentially influencing community dynamics via competition and/or …

Lessons to learn from all out invasion: life history of brown trout (Salmo trutta) in a Patagonian River
… their initial introduction, possibly after near extirpation of native galaxiid fish and reduction of invertebrate biomass. Sites supporting resident fish were narrower, and exhibited higher levels of specific conductance and soluble reactive phosphorous than those supporting both resident and …

Ecology of Mountain Lions (Puma concolor) in the North Dakota Badlands: Population Dynamics and Prey Use
… Dakota Badlands nearly a century after their extirpation; due to the relatively recent reappearance of mountain lions in the region, most population metrics are unknown. From 2011‒2013, we fitted 14 mountain lions with GPS collars and ear-tagged an additional 8 to study the characteristics of …
