The Mojave Poppy Bee (Perdita Meconis) And A Primary Plant Host, The Las Vegas Bear Poppy (Arctomecon Californica): Status And Interactions, Sarit Chanprame

All Graduate Theses and Dissertations, Fall 2023 to Present

The Mojave Desert is one of the most biodiverse places in North America. A harsh environment with many species results in complex relationships between animals and plants. This study focuses on one bee-plant relationship, the Mojave poppy bee, and the Las Vegas Bear Poppy.

The Mojave poppy bee is rare and has only been collected from Las Vegas Bear Poppy, Dwarf Bear Poppy, and a few species of prickly poppies. A 1995 report suggested the bee was a major contributor of pollination for the Las Vegas Bear Poppy in Clark County, Nevada. More recently (2019), their local extinction in southwestern …

Population Physiology, Demography, And Genetics Of Side-Blotched Lizards (Uta Stansburiana) Residing In Urban And Natural Environments, Spencer B. Hudson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wildlife populations across the globe are poised to lose their natural habitat to urbanization, yet there is limited information on how different species handle living in cities. Animals in urban environments are often susceptible to novel stressors, which can threaten their individual health and population viability. The physiological characteristics of animals, such as those related to metabolic hormones, oxidative stress, and immunity, are expected to be important for survival in this context. If so, animals persisting in urban areas may demonstrate physiological differences from their natural counterparts, perhaps due to evolutionary change. These potential outcomes have been documented in birds …
