  Abstract

Pomacea paludosa (native Florida apple snail) is found in wetlands in the southeastern United States. Pomacea insularum is an exotic apple snail which has invaded wetlands in Florida and co-occurs with P. paludosa. The effect of changes in density on growth in native juvenile snails was studied by manipulating native juvenile density, native adult density and exotic adult density in a set of laboratory experiments. Growth decreased when native juvenile densities (without adults) increased from four to eight snails per 38-l aquarium. The presence of adults of either species decreased juvenile growth and also decreased juvenile survival. One exotic adult had the equivalent effect of three to four native adults. Based on the response of native juveniles to exotic adults, populations of the native apple snail P. paludosa could be negatively impacted by expansion of the exotic snail P. insularum.
