A água é imprescindível à biodiversidade sendo um recurso natural de grande relevância em regiões semiáridas como o Nordeste do Brasil. Com isso, suma importância conhecimento da fauna insetos aquáticos desses ambientes, pois eles podem ser importantes bioindicadores qualidade e ambiente ao seu entorno. Baseado nisso, objetivo desse trabalho foi realizar uma análise faunística a partir d...

Freshwater salinity varies in natural systems and plays a role species distribution. Anthropogenic alterations to freshwater regimes include sea level rise subsequent intrusion of saline waters inland habitats. While mayflies are generalized be sensitive increasing salinity, we still know remarkably little about the physiological processes (and their plasticity) that determine performance chang...

• Biomonitor selection includes feeding styles, which affect chemical bioavailability. Baseline tissue residues provide the benchmark to assess bioaccumulation. Ratios of baseline values are related sediment pollution. Integrative scores based on metal suitable for risk assessment. Development sound criteria and metalloid bioaccumulation assessment in river basins affected by mining activities ...

The male imago of Americabaetis longetron Lugo-Ortiz & McCafferty is described based on nymphs reared on field in the municipality Alfredo Chaves, Espírito Santo state, Brazil. The species can be distinguished from the others male imagos of the genus by the following combination of characters: 1) turbinate eyes uniformly separated from each other, upper surface ellipsoidal; 2) terga with a ligh...
