The goal of this project was to develop a landscape dynamics model to project future trends in forest area, age class distribution, and forest type (cottonwood vs. non-cottonwood) for four remnant floodplain segments on the Missouri River and, for two river segments, project effects of forest changes on abundances of forest bird species. These four river segments have not been channelized or inundated by reservoirs and thus still retain some of the natural abiotic and biotic processes of the Missouri River as it existed before human alteration. Fluvial geomorphic processes on all four, however, were significantly altered by the construction of six dams on the main stem of the river in the mid twentieth century....

Wind power is a promising clean energy technology that has grown rapidly in recent years (EIA 2013). In spite of its environmentally friendly reputation, industrial wind energy generation can have serious impacts on wildlife. Bat and bird collision fatality rates have been alarmingly high at some wind farms. Proper siting of wind facilities may help minimize collision impacts as the wind energy industry continues to grow. Bat and bird fatality rates vary greatly among sites; however, there is no reliable method for assessing collision risk prior to development. My goal was to develop a method for predicting fatality rates based on nocturnal activity patterns measured by ground-level recording of bat and bird calls....

Wetland hydroperiod, the length of time water is available in wetlands, is sensitive to changes in precipitation, temperature and timing due to climate variation. Truncated hydroperiod has major implications for wetland-dependent species (e.g., waterfowl, amphibians) and human water allocation (PPP LCC Need 1). To characterize wetland hydroperiod in the Plains and Prairie Pothole Region, we first identify location and hydroperiod of wetlands using field-based and remotely sensed training data (RapidEye, Landsat). We define hydroperiod as wetland ephemerality, where ephemerality represents the persistence of a wetland across the growing season. We then link hydroperiod to climatic variation by relating climate time-series...
