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...
Effect of Seasonal Changes on Predictive Model Assessments of Streams Water Qua...
Feio, Maria João; Reynoldson, Trefor B.; Graça, Manuel A.In this study we investigate how seasonal variability in aquatic macroinvertebrate communities affects the performance of a predictive model developed to assess environmental quality. Macroinvertebrates were sampled from nine not visibly disturbed sites located in different streams of the Mondego catchment across a full year. Organisms were identified to the lowest practicable taxonomic level and their abundanc...
