Accurate estimates of parameters and demographic rates of wildlife populations are crucial to management and conservation. One parameter of interest is age because it influences multiple demographic rates and behaviors including reproduction, dispersal, migration, and disease transmission. There are a number of methods used to estimate ages of wildlife. One of the most common methods used for mammals is evaluation of patterns in dental eruption and tooth wear. In the first chapter, we evaluate the accuracy associated with estimates of age from dental eruption and patterns of tooth wear for mule deer (Odocoileus hemionus). In the second chapter, we use age estimates validated within the first chapter to explore how age and other maternal factors may influence number of offspring born per litter in mule deer. We further test relative support for two common hypotheses--terminal investment and reproductive restraint--regarding the relationship between age and reproductive investment in this species. Our results will inform conservation, management, and research efforts associated with mule deer.
