Threshold Responses Of Forest Birds To Landscape Changes Around Exurban Development, Todd R. Lookingbill, Marcela Suarez-Rubio, Scott Wilson, Peter Leimgruber
Geography and the Environment Faculty Publications
Low-density residential development (i.e., exurban development) is often embedded within a matrix of protected areas and natural amenities, raising concern about its ecological consequences. Forest-dependent species are particularly susceptible to human settlement even at low housing densities typical of exurban areas. However, few studies have examined the response of forest birds to this increasingly common form of land conversion. The aim of this study was to assess whether, how, and at what scale forest birds respond to changes in habitat due to exurban growth. We evaluated changes in habitat composition (amount) and configuration (arrangement) for forest and forest-edge species around …

A Predictive Model For Soil Seed Bank Outcomes In The Pyrenophora Semeniperda-Bromus Tectorum Pathosystem, Phil Stewart Allen, Susan E. Meyer, Julie Beckstead
Biology Faculty Scholarship
Pyrenophora semeniperda is abundant in soil seed banks of Bromus tectorum, where it kills a fraction of seeds throughout the year. The pathogen engages in a race with host seeds for endosperm resources; the pathogen success is negatively correlated with seed germination speed. We developed a deterministic model to predict pathosystem outcomes (seed death versus seed escape), using seed bank data from 80 sites collected over a 13-year period. The response variable (killed seeds in the spring seed bank) was regressed on multiple predictor variables (pathogen and host densities at seed dispersal, amount and timing of precipitation). Increased mortality …
