Extension of the known distribution range and habitat use of the Tiger Crab Aegla concepcionensis Schmitt, 1942 (Decapoda, Aeglidae)
Extension of the known distribution range and habitat use of the Tiger Crab Aegla concepcionensis Schmitt, 1942 (Decapoda, Aeglidae) The tiger crab Aegla concepcionensis Schmitt, 1942 (Decapoda, Aeglidae) is a threatened freshwater decapod, endemic of Chile, with significant gaps in knowledge about its biology and ecology. The aim of this work was to contribute to the knowledge of the ecology of A. concepcionensis, through the extension of its known distribution range, recorded in a new type of ecosystem, and the description of the physicochemistry, vegetation and benthic macroinvertebrate and microalgal communities of those sites, which provides information about habitat use of the species. Our results show the presence of A. concepcionensis until 270 km south of the previously described range and reveal that the species inhabits streams and lakes.

期刊介绍:
Limnetica publishes original research articles on the ecology of inland waters. The scope of Limnetica includes the ecology of rivers, lakes, reservoirs, coastal lagoons and wetlands, as well as biogeochemistry, paleolimnology, development of new methodologies, taxonomy, biogeography and any aspect of theoretical and applied continental aquatic ecology such as management and conservation, impact assessment, ecotoxicology and pollution. Limnetica will accept for its publication scientific articles presenting advances in knowledge or technological development, as well as as papers derived from new practical approaches on the topics covered by the journal.
