Energetic Tradeoffs, Infection, And Immunity In Wild Chimpanzees Of Uganda And Tanzania, Sarah Renee Phillips
Anthropology ETDs
Infectious disease is a primary source of mortality for most mammal species, but scientists have little understanding of factors driving variation in infection and immunity between individuals, populations, and species in the wild. Life history theory provides an evolutionary framework for delineating distribution of available energy to competing physiological demands, including growth, reproduction, and maintenance. Early life reproduction should be favored over late life survival, but, in long-lived species, reproductive success is strongly tied to survival to old age. Slower pace of reproduction could allow investment in immunity, reducing risk of morbidity and mortality to infectious disease. Additionally, several host …

Effects Of Environmental Change On Ancestral Pueblo Fishing In The Middle Rio Grande, Jonathan W. Dombrosky Dr.

It has long been assumed that fishes were unimportant in the diet of past Pueblo people in the U.S. Southwest. Yet, small numbers of fish remains are consistently recovered from Late pre-Hispanic/Early Historic archaeological sites in the Middle Rio Grande of New Mexico. The end of drought conditions may have impacted food choice and fishing decisions during this time. I use behavioral ecology to understand how fishing could have been an optimal food-getting strategy for Ancestral Pueblo farmers. Stable isotope analysis offers a way to account for environmental change. I provide a refined 13C Suess correction model to support …
