摘要: Abstract Extensive anthropogenic activities including land conversion have been taking place in the Guayas river basin (Ecuador) due to increasing population growth. Land use changes are considered one of key sources affecting ecological water quality basin. Therefore, we investigated effect on both within direct vicinity and a distance 200 m from sampling sites. We which three assessment methods (i.e. data retrieved field protocols, aerial pictures (Google maps) GIS data) is most suitable quantify impact local environmental variables influence quality. To do so, collected macroinvertebrates 120 sites throughout during an integrated campaign. The Biological Monitoring Working Party adapted for Colombia (BMWP-Col) was calculated used assess status basin, based macroinvertebrates. relation between BMWP-Col, other using generalized linear models (GLMs) sensitivity analyses.
