BACKGROUND:Experimental manipulations of floral nectar in food deceptive species can reveal insights into the evolutionary consequences of the deceptive strategy. When coupled to pollen tracking, the effects of the deceptive pollination syndrome on b

Phytophthora sojae is a major pathogen in cultivated soybeans world-wide. Although incorporating resistance genes has been an effective management tool for soybean breeders, surveys of soybean fields in the Midwest US indicate that some P. sojae stra

Lupinus is known to form endophytic associations with both nodulating and non-nodulating bacteria. In this study, multilocus sequence analysis (MLSA) was used to analyze phylogenetic relationships among root nodule bacteria associated with Lupinus an

Although hydroperiod and water chemistry are thought to control temporary wetland macroinvertebrate diversity, their effects are often only detected at the ends of hydrological and water quality gradients. However, canopy cover and other biotic facto

Ecological disturbances structure plant communities. In areas where reintroducing natural disturbances is unfeasible, land managers use artificial disturbances, such as fire and mowing, to simulate natural disturbances. However, prescribed fire and m

Wild Lupine (Lupinus perennis) is an indicator of Midwestern U.S.A. oak savannas and the main larval food for endangered Karner Blue butterflies. In the past 100 y, this perennial has declined in distribution and abundance. To determine if this decli

Premise of the study: Understanding floral resources is vital for restoring pollinators in habitats affected by anthropogenic development and climate change. As the primary adult food, nectar can limit butterfly longevity and reproduction. For pollin

Both the number and the density of flowering plants in a population can be important determinants of pollinator abundance and behavior. We report the joint effects of population size and density on pollinator visitation and pollination success for Lu

We examined the effects of self-pollination and resource addition to maternal plants of Wild Lupine on seed production in the field, and on offspring performance in the greenhouse. Although 24% of flowers set fruits when open-pollinated, only 11% of
