Apple snail remains after being preyed upon by a raccoon
August 1, 2017

The maculata apple snail (Pomacea maculata) has invaded many coastal and some inland areas in south Louisiana. Reports have indicated that the freshwater snails have significantly reduced the amount of submerged aquatic vegetation (SAV) and floating leaved vegetation (FLV) available for waterfowl and other wildlife.

Assessing welfare of individual sirenians in the wild and in captivity

The understanding of sirenian welfare requirements, and a...

The role of parasites in trophic ecology is poorly understood in marine ecosystems.
