Global change assessments have typically ignored synthetic chemical pollution, despite the rapid increase of pharmaceuticals, pesticides, and industrial chemicals in environment. The paucity research on ecological effects these micropollutants undermines our efforts to address freshwater biodiversity crisis. Understanding responses individual organisms pollution should help this knowledge gap b...

The freshwater shrimp genus, Neocaridina Kubo, 1938, comprises a group of land-locked organisms of the family Atyidae which is distributed throughout Russia, Korea, Japan, China, Taiwan, and Vietnam (Cai 1996, Liang 2004). Unlike the genera Caridina and Macrobrachium with both catadromous and land-locked species, all known species of Neocaridina are land-locked as evidenced by the abbreviated l...

In an experimental study, we compared reproductive and developmental traits of endemic sesarmid crabs from Jamaica living in landlocked limnic or terrestrial habitats. Laboratory rearing and behavioral observations showed that the larval development of Sesarma windsor, Sesarma dolphinum (both from freshwater brooks), and Metopaulias depressus (the bromeliad crab) invariably consists of two nonf...

The dynamic nature of habitat patches in rivers is driven primarily by flow regime. Altered hydrology, through river regulation, can limit the size and distribution of slackwater patches; important areas for the development of young fish and for shrimp in lowland rivers. Between late October 2002 and late January 2003, we investigated responses of fish, shrimp and their potential prey to the ex...
