The Osage orange (Maclura pomifera) is considered anachronistic because it has no known seed disperser. However, anecdotal observations suggest squirrels (Sciurus spp.) may act as dispersers as they move fruits away from parent plants and through the

While arthropod herbivory on invasive plant species is generally low, herbivory by generalist mammals is often high. We tested whether exclusion of white-tailed deer, Odocoileus virginianus, increased the cover and growth of Lonicera maackii, an inva

Polyploidy is common in nature, particularly among plants, and is often associated with significant morphological, ecological, and evolutionary change. These changes may contribute to prezygotic and postzygotic isolation between cytotypes; therefore,

Habitat loss from agricultural expansion is one of the leading causes of endangerment for terrestrial vertebrates. Restoration programs such as the Conservation Reserve Program (CRP) and State Acres for Wildlife Enhancement (SAFE) were initiated in p

Early successional habitats are declining in eastern North America while at the same time remaining habitats are being invaded by a suite of nonnative shrub species. While the significance of these transitional habitats to breeding birds is well know

This study examines the role mycorrhizae may play in protecting host plants from a soil fungal pathogen. Asexual propagules of three Allium vineale genotypes were grown in the presence and absence of mycorrhizae and the pathogen, Sclerotium cepivorum

Studies of pollination biology are largely diurnally biased, especially in plant species whose flowers conform to diurnal pollination syndromes. Though these syndromes can be useful in generating hypotheses regarding a species’ primary pollinators,

Numerous authors have studied the diet of the Eastern Red-backed Salamander (Plethodon cinereus) and have described this species as a generalist predator of invertebrates. In most studies, prey taxa are identified to the family or order level. Additi

Seed dispersal by animals is an important plant-animal mutualism, but saurochory, the dispersal of seeds by reptiles, is an understudied phenomenon despite its prevalence in many taxa. The effects of seed ingestion by the gopher tortoise (Gopherus po

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
