A new substrate for sampling deep river macroinvertebrates [PDF]
We compared macroinvertebrate communities colonising multiplate samplers constructed from perspex or tempered hardboard (wood) with an alternative artificial substrate constructed from folded coconut fibre matting (coir) enclosed in nylon netting ...

The construction of dams and reservoirs to meet increasing water and electricity demands has significantly altered many natural river flows, posing threats to the ecological integrity of freshwater ecosystems. Environmental flows (e‐flows) have been advocated to mitigate the negative impacts of hydroelectric power generation and to maintain healthy ...

Benthic and hyporheic invertebrate community responses to seasonal flow recession in a groundwater-dominated stream [PDF]
Natural hydrological variability in lotic ecosystems can include prolonged periods of flow recession. A reduction in discharge is accompanied by abiotic changes in benthic and hyporheic habitats, often including reductions in s habitat availability ...

Oligochaeta of the Danube River — a faunistical review [PDF]
The aim of this work is to discuss the distribution of Oligochaeta (Annelida) in the Danube River using the collections made by the Joint Danube Survey 2007 (JDS2) on more than 2800 km of the river. The basic faunistical features of the oligochaete assemblages were analysed with regard to three main sectors of the Danube (upper, middle and lower ...

Biodiversity in mountain soils above the treeline
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...
