COMPARING COMMUNITY REESTABLISHMENT IN INTERMITTENT ECOSYSTEMS: SIMILARITIES BETWEEN STREAMS AND WETLANDS IN INITIAL DEVELOPMENT
The study of intermittent streams and wetlands role within landscape has increased as their protection has diminished. Macroinvertebrates that exist within these habitats must be able to survive desiccation or recolonize when rewetting occurs. Comparing the communities following rewetting between these two intermittent ecosystems could provide insight into what factors control their restructuring. We examined macroinvertebrate reestablishment in an intermittent stream and a geographically isolated wetland in southwest Georgia with. In 2015 samples at three sites within the intermittent stream were taken monthly from dominant habitat types as well as drift samples to examine colonization sources following rewetting. In 2018, we examined macroinvertebrates within a cypress swamp using litter bags following inundation. Similarities between these two ecosystems were seen with early colonizers consisting of crustacean taxa as well as Chironomidae. Within two months, differences could be seen as more rheophilic taxa began to colonize the intermittent stream while wetland samples continued to be dominated by crustaceans and Chironomidae taxa as well as some predators. Similarities in initial development between these ecosystems points to the important role early colonizers such as crustaceans and Chironomidae play in early development of these communities.
