The Periaqueductal Grey In Opioid Tolerance And Chronic Pain, Akila Ram Aug 2021

The Periaqueductal Grey In Opioid Tolerance And Chronic Pain, Akila Ram

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Pain is the body’s natural warning system to indicate one is in an environment highly detrimental to survival. The body’s response to the sensation of pain is to immediately withdraw from this environment, ensuring continued survival. However, when pain lasts beyond the window in which it is useful, it no longer serves as a helpful warning system but instead degrades the quality of life. Chronic pain leads to patients seeking opioids to alleviate their condition and regain control of their lives. A severe negative side effect of the use of opioids to treat chronic pain is the development of tolerance …


The Velvet Ants (Hymenoptera: Mutillidae): Systematics, Biology, And Biogeography Of A Little-Known Family, George Charles Waldren May 2021

The Velvet Ants (Hymenoptera: Mutillidae): Systematics, Biology, And Biogeography Of A Little-Known Family, George Charles Waldren

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Insects are a ubiquitous and species-rich component of the biologically-diverse planet we inhabit. The majority of insects are understudied, with many species awaiting formal description and their natural history yet to be discovered. Members of the family Mutillidae, commonly known as velvet ants, are one of these little-known insect groups. Velvet ants are technically wasps, and the wingless females superficially resemble true ants of the family Formicidae. Further, they frequently have a ‘velvety’ appearance and are often brightly colored to serve as a warning to would-be predators that they have the ability to inflict a painful sting. These insects are …


Greater Sage-Grouse And Community Responses To Strategies To Mitigate Environmental Resistance In An Anthropogenic Altered Sagebrush Landscape, Justin R. Small May 2021

Greater Sage-Grouse And Community Responses To Strategies To Mitigate Environmental Resistance In An Anthropogenic Altered Sagebrush Landscape, Justin R. Small

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sagebrush (Artemisia spp.) ecosystems are diverse habitats found throughout western North America. Anthropogenic disturbances has resulted in the loss of over half of the sagebrush ecosystems impacting sagebrush obligate species such as sage-grouse (Centrocercus spp.). Federal, state, and private land managers have implemented landscape scale mechanical pinyon (Pinus spp.) and juniper (Juniperus spp.; conifer) removal projects in an effort to restore functioning sagebrush communities to benefit sage-grouse. However, few studies have investigated the potential for using large-scale conifer treatments to mitigate factors impeding sage-grouse seasonal movements and space-use in anthropogenic altered landscapes.

To address this management need, I …
