Ecology of Terrestrial Arthropods in Freshwater Wetlands.

The terrestrial arthropod fauna of wetlands has been largely ignored by scientists compared to other ecological elements, yet these organisms are among the most important influences on the ecology of these systems, with the vast majority of the biodiversity in wetlands found among the terrestrial arthropods. Wetlands present a range of habitat for terrestrial arthropods, with unique faunas being associated with soils and ground litter, living-plant substrates, and peatlands. Myriapoda, Araneae, Collembola, Carabidae, Formicidae, and assorted herbivorous Coleoptera and Lepidoptera are the terrestrial arthropod groups that most influence the ecology of wetlands. Despite their success, most terrestrial arthropods possess fairly rudimentary adaptations for life in wetlands, with most simply moving to higher ground or up vegetation during floods, although some species can tolerate immersion. Many terrestrial arthropods are environmentally sensitive and show considerable promise as bioindicators of wetland ecological conditions.
