Brazilian Journal of Biology, 2011 Dams are a major threat to aquatic biological diversity. By altering the natural flow of rivers, dams modify fluvial habitats, making them unsuitable for the growth and reproduction of many aquatic species.

The macroinvertebrate seedbank promotes community persistence in temporary rivers across climate zones [PDF]
, 2013 1. Aquatic macroinvertebrates inhabiting temporary rivers are typically described as having low resistance to riverbed drying. However, little research has examined the ‘seedbank’ within dry riverbed sediments, which comprises aquatic life stages that ...

River Research and Applications, EarlyView.ABSTRACT In large, meandering rivers, much of the instream flow veers around islands through secondary channels (SCs), which often comprise a substantial proportion of a river's longitudinal path. Due to their dissimilar hydrological conditions, within and among themselves and to the main channel (MC), SCs augment habitat diversity and biogeochemical ...

Cladistics, EarlyView.Abstract Scherotheca is amongst the most diverse earthworm genera within Lumbricidae, exhibiting striking ecomorphological radiation—from small epigeic‐like forms to giant anecic species. Accurate systematics is critical for exploring such diversification.

Ecological Entomology, EarlyView.The height at which epiphytic bromeliads are found affects the invertebrate community composition within them. The size of epiphytic bromeliads is positively correlated with species richness of both aquatic and terrestrial invertebrates. Whether bromeliads were found in primary or secondary forest did not have a significant effect on the community of ...

Restoration Ecology, EarlyView.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 ...

Restoration Ecology, EarlyView.Abstract Introduction In the Upper Danube River, a key goal of river–floodplain restoration is to enhance hydrological connectivity and reduce aquatic habitat isolation and terrestrialization. To evaluate restoration effectiveness, it is crucial to understand the functional responses of freshwater biodiversity and the role of connectivity and ...
