Individual And Population Responses To Hydrologic Variability In A Headwater Stream Salamander, Madaline Cochrane
Individual And Population Responses To Hydrologic Variability In A Headwater Stream Salamander, Madaline Cochrane
Graduate Student Theses, Dissertations, & Professional Papers
Understanding how organisms respond to environmental variability is a central goal in ecology – a goal made even more pressing by the herculean challenge global climate change presents to all organisms. Climate change is increasing the frequency and intensity of floods and droughts, which will likely have disproportionate effects on freshwater organisms. Many stream-associated species have multi-stage life histories. However, we lack an empirical understanding of life history and movement responses of these organisms to hydrologic disturbances, and how these responses may influence demographic rates. In my dissertation, I used a combination of growth, developmental, movement, and demographic data to …
Survival, Movements, And Resource Selection Of Female White-Tailed Deer In Missouri, Chloe A. Wright
Survival, Movements, And Resource Selection Of Female White-Tailed Deer In Missouri, Chloe A. Wright
Graduate Student Theses, Dissertations, & Professional Papers
White-tailed deer (Odocoileus virginianus) in Missouri are a socially and economically important game species generating annual revenue in excess of $1 billion. The last comprehensive deer study in Missouri was conducted in the 1980s – 1990s when deer populations were rapidly expanding. Since this time there has been a reduction in deer population size, declining growth rates, changes in harvest strategies, and the emergence and spread of chronic wasting disease (CWD). These changes have rendered prior survival estimates outdated, and the presence of CWD requires a deeper understanding of movement patterns and space use. We were interested in …
