Relative impacts of morphological alteration to shorelines and eutrophication on littoral macroinvertebrates in Mediterranean lakes [PDF]
Development of effective methods for assessing the ecological status of lakes based on littoral benthic fauna has been hampered by the lack of quantitative data on the relative impacts of key pressures on the benthic community.

Sampling effort to characterize estuarine macroinfaunal communities in patchy habitats
Abstract Estuarine benthic macroinfauna have aggregated, patchy distributions, making accurate community measurements dependent upon sampling scales. The purpose of this study is to determine the appropriate core sizes and sampling effort needed to characterize benthic infaunal communities in Corpus Christi Bay, Texas, USA.

ABSTRACT Low‐tech process‐based stream restoration (LTPBR) is increasingly implemented following wildfire, underscoring the need to evaluate restoration outcomes in burned catchments. To help address this need, we measured abiotic and biotic characteristics of a reach that received LTPBR, an untreated reach, and a reach with relict beaver activity that

ABSTRACT Ditches are essential elements of the agricultural landscape because of their role as habitat or refuge for aquatic species, especially in homogenized and intensively cultivated areas. However, data on the biodiversity associated with agricultural ditches, and its variation over time, are underrepresented in ecological research.

Macroinvertebrates and water quality: a teaching guide [PDF]
Streams support a diverse community of plants and animals on or in the stream bed. These organisms comprise the benthos. Among the benthos are worms, molluscs, crustaceans, and larval insects.
