Aim Macroinvertebrates comprise a highly diverse set of taxa with great potential as indicators soil quality. Communities were sampled at 3,694 sites distributed world-wide. We aimed to analyse the patterns abundance, composition and network characteristics their relationships latitude, mean annual temperature rainfall, land cover, texture agricultural practices. Location Sites are in 41 countr...

Pesticides are constantly being applied to agricultural catchments, but little is known about their impact on aquatic biota during natural exposure. In the present study, the impact of the pyrethroid lambda-cyhalothrin was studied in an in-stream mesocosm setup. Twice during the summer of 2002, the natural macroinvertebrate community was exposed in situ to a 30-min pulse of lambda-cyhalothrin. ...

The quality of stream ecosystems in many areas of the world is significantly degraded as a result of conversion of natural landscapes to urban and agricultural uses. Impacts of these activities can be observed in the organization of the benthic macroinvertebrate communities, which have distinct responses to physical, chemical, and biological disturbances. However, the information relating anthr...
