Benthic Macroinvertebrate Diversity in the Middle Doce River Basin, Brazil

Abstract

This resource contains a checklist of the benthic macroinvertebrate community sampled biannually from 1999 to 2010 in eight natural lakes from the middle Rio Doce Valley lake system and eight river segments in the Piracicaba River basin (sub-basin of Doce river), Minas Gerais State, Brazil. Three of the lakes are located inside a protected state park and are surrounded by preserved vegetation (Atlantic Forest). The other five lakes are in private properties, surrounded by Eucalyptus plantations. The seven stretches of rivers have a distinct degree of anthropogenic impacts. Samples were collected with a kick net and fixed with formaldehyde solution. Four phyla were represented: Mollusca, Annelida, Arthropoda, and Platyhelminthes. For Insecta, 76 families were identified, one family was identified for Crustacea, and nine families were identified for Mollusca.

Four New Caddisfly Species of Marilia Müller, 1880 (Trichoptera: Odontoceridae) from a Tailings Dam Disaster Area, Rio Doce basin, Brazil

“…This is the first study to identify Odontoceridae at the species level in the Rio Doce basin. Studies on water quality using benthic macroinvertebrates were performed in the basin prior to the dam disaster but specimens were identified only at the family level, some of them reporting the occurrence of Odontoceridae [39][40][41][42][43].…”

Análise faunística de insetos aquáticos das nascentes da Chapada do Araripe no Nordeste do Brasil

“…Ordem Dentre os dípteros, a família Chironomidae foi a mais abundante em todas as fontes (2.497 indivíduos). Os quironomídeos são um dos insetos mais frequentes e abundantes em ambientes aquáticos, como visto nos trabalhos de Barbola et al (2011), Battistoni et al (2012), Zardo et al (2013), Aguila et al (2018), Chagas et al (2017. Esta família de mosquitos coloniza ambientes aquáticos continentais, sendo um dos macroinvertebrados bentônicos mais utilizados como bioindicadores da qualidade de água devido a sua elevada riqueza e abundância nos ambientes (BEM et al, 2015).…”
