Our goal was to understand how a gradient of deforestation may affect abundance and richness of specialist and generalist macroinvertebrates associated with submerged woody debris in Neotropical streams. We conducted an observational study sampling mixed-species woody debris from 16 streams along a deforestation gradient. We also conducted an incubation study with known woody debris species (Cecropia pachystachya Trécul) in six streams. We collected 781 specimens and identified 50 taxa in the observational study, and we found 99 individuals belonging to 17 taxa in incubation study. Results from the two complementary studies indicate that the effect of riparian deforestation was more pronounced for wood specialists than generalists. Deforestation decreased the abundance and richness of wood specialists, and some taxa were locally extinct. The incubation study showed that sedimentation, which leads to the burying of woody debris, is an important process impeding macroinvertebrate colonization. Our study highlights the importance of woody debris as habitat for aquatic communities and as a structural component of streams, with important implications for conservation and biomonitoring. We suggest that wood specialists could be a potential group for use in biomonitoring programs aimed at assessing the impact of deforestation.
