Fish and macroinvertebrate assemblages reveal extensive degradation of the worl...
Feio, Maria João; Hughes, Robert M.; Serra, Sónia R. Q.; Nichols, Susan J.; Kefford, Ben J.; Lintermans, Mark; Robinson, Wayne; Odume, Oghenekaro N.Rivers suffer from multiple stressors acting simultaneously on their biota, but the consequences are poorly quantified at the global scale. We evaluated the biological condition of rivers globally, including the largest proportion of countries from the Global South published to date. We gathered macroinvertebrate- and fish-based assessments from 72,275 and 37,676 sites, respectively, from 64 study regions acros...
The Biological Assessment and Rehabilitation of the World’s Rivers: An Overview
Feio, Maria João; Hughes, Robert M.; Callisto, Marcos; Nichols, Susan J.; Odume, Oghenekaro N.; Quintella, Bernardo R.; Kuemmerlen, MathiasThe biological assessment of rivers i.e., their assessment through use of aquatic assemblages, integrates the effects of multiple-stressors on these systems over time and is essential to evaluate ecosystem condition and establish recovery measures. It has been undertaken in many countries since the 1990s, but not globally. And where national or multi-national monitoring networks have gathered large amounts of d...
