Seasonal records of benthic macroinvertebrates in a stream on the eastern edge of the Iguaçu National Park, Brazil

A study on the eastern edge of Iguaçu National Park, Brazil, reveals that seasonal climatic conditions significantly influence the abundance and composition of benthic macroinvertebrates. Researchers identified 88 taxa, with Diptera being the most abundant and diverse order. The findings indicate higher occurrences and diversity during intermediate and lower precipitation/temperature periods, suggesting a varied response to environmental factors. This research enhances our understanding of stream ecosystems in biodiversity hotspots like the Atlantic Forest, providing critical data for biomonitoring efforts amid ongoing anthropogenic threats.
