Species delimitations and understanding the processes that drive speciation are essential to nearly all aspects of human endeavor. Determining species boundaries traditionally used morphology. Phylogenetic analyses based on DNA sequence data provide a means to resolve species boundaries, as well as test hypotheses regarding the evolutionary processes. Numerous species radiations have occurred in Western North America. Among these are several plant groups such as Astragalus, Artemisia, and Lomatium. Recent phylogenetic analyses of Lomatium and related genera have demonstrated that many of the morphological characters used to delimit taxa have arisen multiple times and that most taxa are para- …

Anthropogenic noise has proven detrimental to organisms like bats, owls, and certain other species whose hunting or navigation success is affected by unnatural sound. However, few studies have quantified the effects of noise pollution across multiple trophic levels. Our study is quantifying the impacts of human noise on insect abundance and herbivory, and plant physiology, using experimental noise stations compared to quiet control sites in the sagebrush steppe southwest of Boise, Idaho. I am measuring variation in leaf chlorophyll fluorescence and Normalized Difference Vegetation Index (NDVI). Both of these measurements are indirect measurements of photosynthetic capacity. We hypothesized that shrubs …
