Plague Risk In The Western United States Over Seven Decades Of Environmental Change, Colin J. Carlson, Sarah N. Bevins, Boris V. Schmid

United States Department of Agriculture Wildlife Services: Staff Publications

After several pandemics over the last two millennia, the wildlife reservoirs of plague (Yersinia pestis) now persist around the world, including in the western United States. Routine surveillance in this region has generated comprehensive records of human cases and animal seroprevalence, creating a unique opportunity to test how plague reservoirs are responding to environmental change. Here, we test whether animal and human data suggest that plague reservoirs and spillover risk have shifted since 1950. To do so, we develop a new method for detecting the impact of climate change on infectious disease distributions, capable of disentangling long-term trends (signal) and …

A Model For Leveraging Animal Movement To Understand Spatio-Temporal Disease Dynamics, Mark Q. Wilber, Anni Yang, Raoul Boughton, Kezia R. Manlove, Ryan S. Miller, Kim M. Pepin, George Wittemyer

United States Department of Agriculture Wildlife Services: Staff Publications

The ongoing explosion of fine-resolution movement data in animal systems provides a unique opportunity to empirically quantify spatial, temporal and individual variation in transmission risk and improve our ability to forecast disease outbreaks. However, we lack a generalizable model that can leverage movement data to quantify transmission risk and how it affects pathogen invasion and persistence on heterogeneous landscapes. We developed a flexible model ‘Movement-driven modelling of spatio-temporal infection risk’ (MoveSTIR) that leverages diverse data on animal movement to derive metrics of direct and indirect contact by decomposing transmission into constituent processes of contact formation and duration and pathogen deposition …

Human–Wildlife Interactions

The management of free-roaming horses (Equus ferus) and burros (E. asinus) in the United States has been referred to as a “wicked problem” because, although there are population control options, societal values will ultimately determine what is acceptable and what is not. In the United States, free-roaming equids are managed by different types of organizations and agencies, and the landscapes that these animals inhabit vary widely in terms of access, size, topography, climate, natural resources, flora, and fauna. This landscape diversity, coupled with contemporary socioeconomic and political environments, means that adaptive management practices are needed to …

The Effect Of High Dose Ascorbic Acid And High Dcad Administration On Oxidative Stress And Mammary Gland Function Of Dairy Goat Fed Under Tropical Condition, Sapon Semsirmboon Jan 2022

The Effect Of High Dose Ascorbic Acid And High Dcad Administration On Oxidative Stress And Mammary Gland Function Of Dairy Goat Fed Under Tropical Condition, Sapon Semsirmboon

Chulalongkorn University Theses and Dissertations (Chula ETD)

High ambient temperature (HTa) increased the respiration rate (RR) and rectal temperature (Tr) of dairy goats. The excess response resulted in acid-base imbalance, electrolyte imbalance, and systemic oxidative which could indirectly affect the mammary gland. Besides, HTa did directly alter cell function, and this has been proposed to be mediated by oxidative stress. We previously showed that high dietary cation and anion differences (DCAD) could decrease the HTa effect. In dairy cows, a high dose ascorbic acid (Asc) has been used to decrease oxidative stress. Then, It was hypothesized whether mammary gland function could be altered when the HTa was …
