Benthic macrofauna and the limnological parameters of a first-order stream in Atlantic Forest of Brazilian Northeast

Abstract: Aim:The present study aimed to elucidate if the water physical and chemical parameters from a first order stream of Biological Reserve of Saltinho from south Pernambuco induces in the distribution and abundance of benthic macroinvertebrates. Methods: Both limnological parameters (pH-value, electrical conductivity, water temperature, turbidity, salinity and dissolved oxygen) and structural variables of aquatic habitat (substrate, food availability and flow velocity) influence the macroinvertebrates community st… Show more

“…The seven species analyzed mainly consumed aquatic macroinvertebrates represented basically by immature forms of insects, which is associated to the high abundance and richness of these organisms in the studied streams and observed in others studies (Allan, 1995;Buckup et al, 2007;Rezende et al, 2011;Cunha et al, 2014). Although all species have consumed insects, interspecific differences in diet were recorded for most of them, evidencing the trophic segregation and the differential use of the available resources in the environment.…”

“…O riacho nasce fora da área da REBIO Saltinho e apresenta seu fluxo principal de noroeste para sudoeste, atravessando a REBIO Saltinho e desaguando no Rio Mamucabas, próximo à foz, no Oceano Atlântico (Cunha et al, 2014). Na área da REBIO Saltinho, a bacia abrange área de 475 ha, constituindo a totalidade da REBIO Saltinho.…”

“…Devido a essas questões, relativas à importância dos macroinvertebrados no processo de decomposição, é que esse estudo procura elucidar a importância dos fragmentadores no processo de decomposição de detritos foliares em riachos de 1ª ordem, em uma área protegida de Mata Atlântica inserida em uma unidade de conservação de proteção integral, que fornece serviços ecossistêmicos e ambientais relevantes para a Mata Sul do Estado de Pernambuco. No Estado de Pernambuco não há estudos sobre macroinvertebrados bentônicos em riachos voltados para análise da estrutura e distribuição desses (Cunha et al, 2014). Na Mata Atlântica de Pernambuco, historicamente, grandes áreas foram convertidas em monoculturas de cana-de-açúcar, sendo esses pequenos fragmentos de mata importantes para a manutenção dos cursos d'água.…”
