The direct predatory effects of introduced rainbow trout Oncorhynchus mykiss on native longnose dace Rhinichthys cataractae were examined using a series of in-stream enclosures to determine if presence, density, or acclimation period of rainbow trout influenced survival of longnose dace. The number of longnose dace remaining in enclosures over the first 72 hours after rainbow trout introduction...

Mixed-species flocks result from co-evolved relationships between participants: interspecific gregariousness that varies in strength in different species pairs or groups. Such inter-specific associations of birds are a characteristic of most avian communities, observed in diverse habitats from forests to grasslands, estuaries to the open ocean, worldwide in both high latitudes and in the tropic...

The nutria is a large (over 6 kg), semi-aquatic rodent with a voracious appetite and high reproductive potential. Nutria became established in the Louisiana wetlands in the 1930’s.
