dc.description.abstractBenthic macroinvertebrates are considered important bioindicators of water quality, and their distribution is influenced by several factors, including food availability. This feeding is an essential factor for all living beings and determines aspects of temporal and spatial population dynamics and relations between individuals and their respective habitats. The present work aimed to analyze the diet of nymphs of the order Plecoptera associated with quartzite caves located in southern Minas Gerais state, Brazil. The stomach contents of 79 specimens were analyzed, and many were empty (40.5 %). Among the nymphs with stomach contents, the most frequent content was fine particulate organic matter. The high amount of individuals with empty content may indicate a low tolerance of these organisms to subterranean environments.pt_BR
dc.description.abstractMacroinvertebrados bentônicos são considerados importantes indicadores de qualidade de água, sendo sua distribuição influenciada por fatores como alimentação. Essa preferência é um fator essencial para seres vivos e determina aspectos da dinâmica populacional temporal e espacial. O trabalho teve como objetivo analisar a dieta de ninfas de Plecopteras associa-das a cavernas quartzíticas no sul do estado de Minas Gerais. Foi analisado o conteúdo estomacal de 79 espécimes e muitos estavam vazios (40,5 %). Entre as ninfas que possuem conteúdo estomacal, o mais presente foi a matéria orgânica particulada fina. A grande quantidade de indivíduos com o estômago vazio pode indicar baixa tolerância desses organismos a ambientes subterrâneos.pt_BR
