The Vascular Flora Of Boone County, Iowa (2005-2008), Jimmie D. Thompson Jan 2010

The Vascular Flora Of Boone County, Iowa (2005-2008), Jimmie D. Thompson

Journal of the Iowa Academy of Science: JIAS

A vascular plant survey of Boone County, Iowa was conducted from 2005 to 2008 during which 1016 taxa (of which 761, or 75%, are native to central Iowa) were encountered (vouchered and/or observed). A search of literature and the vouchers of Iowa State University's Ada Hayden Herbarium (ISC) revealed 82 additional taxa (of which 57, or 70%, are native to Iowa), unvouchered or unobserved during the current study, as having occurred in the county. This total of 1098 taxa (979 species, 57 varieties, 39 subspecies, 23 hybrids) places Boone County first in vascular plant richness among 18 published county inventories …

Human–Wildlife Interactions

Introduced vertebrates have a variety of impacts on ecosystems and economies, and many cause problems for humans. One such problem is the loss of electrical power when invasive animals cause short circuits in power-transmission equipment. Cuban treefrogs (Osteopilus septentrionalis) are known to cause power outages and are a nuisance to humans when they invade homes and defecate on doors and windows. These large, slightly toxic treefrogs were introduced into Florida from the Caribbean. They now occur throughout the peninsula of Florida and are spreading to other states in the Southeast. We used refuge choice experiments to test the …
