Movements of coastal brook trout after dam removals
Brook trout (Salvelinus fontinalis; Figure 1) are a species of char native to the eastern half of North America. Though commonly associated with headwater streams in the mountains, populations of […]
Habitat preferences and movements of non-native rainbow trout
In many coldwater rivers and streams around the world, nonnative trout have altered the aquatic ecosystem. In the late 1800s, widespread trout stocking became commonplace and various trout species were […]
Spawning sea lampreys influence macroinvertebrate communities in streams

Effects of dam removals on riverine fish assemblages
In many rivers throughout the world, dams have greatly altered the aquatic ecosystem. These structures block migratory routes for anadromous species that live in saltwater and migrate into freshwater to […]
Dam removals improve American eel abundance
American eels (Anguilla rostrata) are slimy fish with long, snakelike bodies found along the Atlantic coast from Greenland to Brazil. Like many species of diadromous fish (species that migrate between […]
