1. Cook, Leah. Effects of road salt on photosynthetic and enzyme activity of stream biofilms.

Degree: MS, Biology, 2012, Eastern Michigan University

Road salt application and salt-laden run-off are common, yet little information exists about its influence on periphyton. I measured extracelluar enzyme activity and photosynthetic activity of natural winter stream periphyton communities under various short-term laboratory salt exposures. The results of this study suggest that short-term exposure to increased concentrations of salt did not affect extracelluar enzyme activity but could temporarily reduce the photosynthetic activity of the periphyton. Further work will be necessary to understand the longterm effects of increased salt concentrations on periphyton and extracellular enzyme activity. Advisors/Committee Members: Steven N. Francoeur, PhD, Chair, Peggy Liggit, PhD, Gary Hannan, PhD.

2. McMahon, Susan D. Preference and performance of the wild indigo duskywing (<i>erynnis baptisiae</i>) on its native host yellow wild indigo (<i>baptisia tinctoria</i>) and on the introduced plant crown vetch (<i>securigera varia</i>).

Degree: MS, Biology, 2007, Eastern Michigan University

The Wild Indigo Duskywing butterfly (Erynnis baptisiae) shifted from its native host plant Yellow Wild Indigo (Baptisia tinctoria) to the introduced plant Crown Vetch (Securigera varia). This study examined the effects of this host shift by comparing butterfly preference (larval feeding and female oviposition) and performance (pupal weight and pupation success) of two distinct butterfly populations, on both native and introduced plants. Caterpillars reared on the native plant had significantly greater pupal weight regardless of the population origin. Larval feeding preference was significantly affected by the plant fed upon; larvae from both populations strongly preferred to feed on the native plant. Neither population origin nor host plant significantly affected pupation success or oviposition preference. Greater performance on and feeding preference for the native plant emphasizes that increasing the B. tinctoria population will likely increase the butterfly population.

3. Chartier, Neil Allen. The influence of woodlot size and location in suburban and rural matrices on bird species richness and individual abundance.

Degree: MS, Biology, 2006, Eastern Michigan University

This study assessed the influence of woodlot area and matrix composition on bird species richness and individual abundance. Bird surveys were conducted in winter 2004 and 2005 and spring 2005. Woodlot area and landscape composition were analyzed using GIS software. In winter, resident species richness and abundance increased as landscape diversity increased, whereas in spring, resident species richness decreased with increased landscape openness and abundance increased as woodlot area increased. Spring migrant species richness increased with increased landscape openness, and abundance decreased as woodlot area increased. In winter, Tufted Titmice were more likely to be present in smaller woodlots, whereas in spring, they were somewhat more common in larger woodlots. Tufted Titmouse may exploit the habitat structure of smaller woodlots in fragmented landscapes to increase access to foraging habitat. Conservation strategies that reduce fragmentation and promote greater habitat diversity may lead to greater bird species diversity and abundance. Advisors/Committee Members: Peter Bednekoff, PhD, Chair, Gary Hannan, PhD, Cara Shillington, PhD.
