An assessment of microplastic contamination in freshwater fish from the Upper Doce River basin (Minas Gerais, Brazil): a 2003 baseline study

Microplastics (MPs)—plastic particles smaller than 5 mm—have become a growing environmental concern due to their pervasive presence in aquatic ecosystems. This study investigates the presence of MPs in freshwater fish specimens collected in 2003 in a small urban pond (Upper Doce River basin, Brazil). From the 744 f...

The effect of sugarcane vinasse on the dormant forms of aquatic invertebrates

Abstract: Aim To evaluate the impacts of vinasse on the hatching of dormant forms of aquatic invertebrates, through ex-situ experimental units. Methods Sediment samples were collected from three ponds in Parque Estadual Morro do Diabo, located in Teodoro Sampaio (SP), Brazil. Each experimental unit consisted of 100 g o...

Severe environmental disturbances compromise ecological thresholds in aquatic environments

Large-scale disturbances can profoundly alter aquatic ecosystems by modifying water chemistry, sediment dynamics, and biodiversity across connected freshwater and marine environments. The 2015 Fundão Dam collapse in Brazil provides an unprecedented context to evaluate how multiple aquatic communities respond to intense...

The insecticide fipronil selectively reduces the net emergence of aquatic microinvertebrates from neotropical lake sediment egg banks.

Freshwater environments rely on the sediment dormant invertebrate stages for recolonization and the maintenance of biodiversity after environmental stressors. However, while these resting structures are resilient to natural physical extremes, the effects of anthropogenic contaminants on them remain poorly understood. S...
