Does richness of Oligochaeta (Annelida) follows a linear distribution with habitat structural heterogeneity in aquatic sediments?

open access: yesJournal of Limnology, 2014
Sediment of aquatic environments supports several local communities, among them aquatic invertebrates. Habitat structural heterogeneity in sediments of aquatic ecosystems is related to a number of factors, including variability in the particle size of ...

Using oligochaeta assemblages as an indicator of environmental changes

open access: yesBrazilian Journal of Biology
We designed a field survey (the entire river length; not dammed: First and Second plateaus; dammed: Third Plateau) to test the hypothesis that the cascade of reservoirs promoted a reduction in species richness and changed the composition of Oligochaeta ...

Biofilms, Bugs, and the Built Environment: Exploring Local and Landscape Drivers of Diatom and Macroinvertebrate Assemblages in Urban Stormwater Ponds. [PDF]

open access: yesWater Environ Res
Urban stormwater ponds support pollution‐tolerant diatom and macroinvertebrate assemblages that are shaped more by local water quality, contaminants, and habitat features than by surrounding land use. Integrating biological monitoring can better inform stormwater management and urban biodiversity planning.
