Freshwater Macroinvertebrate Community Responses to Drying Reflect Abiotic Stress, Frequency of Prior Drying and Proximity to a Perennial Reach

Freshwater Biology, Volume 70, Issue 4, April 2025.
ABSTRACT Intermittent streams dominate global river networks and are becoming increasingly common due to global change. Understanding the mechanisms by which freshwater biota respond to flow recession, drying, and intermittence is therefore important to our ability to support biodiversity as ecosystems adapt to ongoing stressors.

Hurricane‐induced changes in mayfly assemblage structure, production and emergence in a tropical island stream Cambios inducidos por los huracanes en la estructura, producción, y emergencia del ensamblaje de Ephemeroptera de una quebrada de isla tropical

Ecological Entomology, Volume 50, Issue 1, Page 201-213, February 2025.
Hurricanes create major disturbances to stream ecosystems by producing large floods and removing riparian vegetation. Understanding their impacts is a priority, as hurricane intensity will increase with global climate change. Hurricane disturbance shifts mayfly assemblages from dominance by Leptophlebiidae before to Baetidae after.

First report of Epibiont ciliates (Ciliophora: Peritrichia) living on larvae of Leptophlebiidae (Ephemeroptera) from Brazil

Brazilian Archives of Biology and Technology, 2017
Epibiosis was understood as a commensalism relation between two or more organisms. However, some studies have shown that epibionts can cause deleterious effects to their host.

Impact of Sugarcane Cultivation on Benthic Macroinvertebrate Communities in Tropical Streams

Limnological Review
Tropical streams host diverse benthic macroinvertebrates, essential for ecological processes and bioindicators of ecosystem health. However, land use changes, such as sugarcane cultivation, negatively impact stream structure and function.
