Hazard and Risk of Anticoagulant Rodenticides to Predatory and Scavenging Wildlife

Invasive mammalian predators are the most damaging group of animals affecting global biodiversity.  When introduced on remote islands, alien rodent species can devastate local biota and have been linked to approximately 30% of all extinctions. In addition, rodents can also consume and spoil crops, and serve as disease vectors that affect humans.  Starting in the 20th century,...

An Analysis of Trends in the Magnitude of Floods in Urbanized Watersheds on Long Island, New York

Summary: This study aims to do a thorough analysis of trends in peak streamflows on Long Island. Reliable information about the magnitude and frequency of floods is essential for flood insurance studies, flood-plain management, and the design of transportation and water-conveyance infrastructure, such as roads, bridges, culverts, dams, and levees. Federal, State, regional, and local officials...

Bird Habitat Needs in the Mississippi Alluvial Valley

Historically the Mississippi Alluvial Valley (MAV) was predominantly bottomland hardwood forest and most birds of conservation concern depend on bottomland hardwood forest.
