How Do Sampling Methods Affect the Body Size–Abundance Relationships of Benthic Macroinvertebrates in Freshwater Ecosystems? A Comparative Analysis
نویسندگان
چکیده
Body size is a key trait of species, populations, and organisms; it relates to abundance, home range, metabolic rates, stressors. As reported by Damuth’s law, the relationship between body abundance negative with slope value −0.75. In aquatic ecosystems, particularly for benthic macroinvertebrates, deviates from expected This variation may depend on abiotic biotic factors as well methods that are used sample macroinvertebrates. “Leaf-bags” “Surber-net” most they provide different data about structures sampled Here, we size–abundance relationships compare macroinvertebrate assemblages two sampling (Leaf-bags Surber-net). We found Leaf-bags greater number smaller taxa than Surber-net, which collected individuals larger sizes. our study, differences in these were evident even if experiment was performed at limited spatio–temporal scale. Therefore, Surber-net should be complementary rather alternative techniques since integrated information communities.

Five lotic systems of Serra do Cipó, south-east Brazil, were investigated in order to assess the existing diversity of benthic macroinvertebrates, habitats-microhabitats, and the available trophic resources. For each river it was analysed the communities of benthic macroinvertebrates and the composition of some taxonomic groups (Plecoptera, Ephemeroptera, Trichoptera and Diptera Chironomidae): ...

In this study, we applied the SOM for ecological assessment using benthic macroinvertebrates in aquatic ecosystem. First, Chapter I, SOM was utilized to extract information from complex data of environmental variables and benthic macroinvertebrate communities residing in different micro-habitats. Although the sampling was carried out in a limited area, the patterns of environmental variables re...
