Concordance between macroinvertebrate communities and the typological classification of white and clear-water streams in Western Brazilian Amazonia

Abstract: In this study we have attempted to answer whether there is correspondence between aquatic macroinvertebrate communities and the typological classification of white and clean-water streams in western Amazonia lowlands. We worked within two distinct hydrographic basins: Moa River catchment (clear-water streams) and Azul River catchment (white-water streams) in Serra do Divisor National Park, Acre State, Brazil, sampling 10 streams in each basin. A total of 2,952 individuals were collected, distributed among 134 … Show more

“…Environmental factors have been suggested as the main factor responsible for structuring freshwater communities (Landeiro et al, 2012;Roque et al, 2012). The biological processes that influence taxa establishment and their persistence in these environments are, often, manifested most strongly at the regional scale, for instance because hydrology of the catchments and inherent geomorphology are pointed out to be the main controlling factor of environmental disturbance at local scale.…”

“…The orders Ephemeroptera, Plecoptera Trichoptera and Odonata also deserve attention regarding the insect conservation in Brazil, due to the increasing number of studies that discuss the relation of the taxa with the environmental quality of the waters [31,32]. Apparently, these issues have been influencing the increasing focus of the authorities regarding the applications in official programs of management and monitoring of watersheds [33] and reinforce the protection for the species in threat of extinction [27].…”

“…Os insetos aquáticos podem ser encontrados em diferentes tipos de corpos d'água como lagos, açudes, rios, riachos, poças d'água, bromélias, entre outros (6)(7)(8)(9)(10). O seu ciclo de vida pode ser integralmente aquático, como ocorre com alguns coleópteros, ou parte na água (fase imatura) e a outra fase no ambiente terrestre (fase adulta), como nas libélulas e efemerópteros (11)(12)(13).…”

“…O seu ciclo de vida pode ser integralmente aquático, como ocorre com alguns coleópteros, ou parte na água (fase imatura) e a outra fase no ambiente terrestre (fase adulta), como nas libélulas e efemerópteros (11)(12)(13). Esses organismos possuem forte relação com o meio aquático e são influenciados por variáveis físicoquímicas, ambientais e hidrológicas (6,(8)(9)(10). Por causa disso, as alterações na mata ciliar ou mesmo em seu entorno produzem mudanças na estrutura dos habitats aquáticos e, consequentemente, pode modificar a composição e riqueza desses insetos, provocando inclusive a extinção deles.…”
