Impact of Seed Predation by Mice on Wild Lupine in and near Oak Savannas

摘要: Abstract Wild blue lupine (Lupinus perennis) in the Oak Openings Region of Northwest Ohio is an important nitrogen fixer and serves as essential food source for federally endangered Karner Blue butterfly (Lycaeides melissa samuelis). In order to examine potential factors that might be affecting mice predation on wild seeds oak savannas, we used seed trays placed open or forested edge estimate rate. We recorded management histories, performed vegetation surveys, GIS find spatial variables related prescribed burning assess how they affect predation. Our major findings were removal by summer averaged across sites was 22%, varied significantly time (P < 0.05), more likely areas with increased crypto-biotic crust 0.0001). Seed rates under burns over last 10 y  =  0.034) 19 years This leads us support cu...
