Environmental Quality Management, Volume 35, Issue 4, Summer 2026.ABSTRACT Mining waste water characteristically contains high concentrations of suspended solids, total metals, and nutrients. These can be treated with flocculants within settling ponds to speed up the clarification of water by settling out the suspended solids.

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.Our findings show that beaver‐engineering significantly enhances local biodiversity across aquatic and terrestrial ecosystems, even at sites with high land‐use intensity. Hence, beavers can effectively restore stream biodiversity across a range of urban to agricultural to natural ecosystems.

Strong diel variation in the activity of insect taxa sampled by Malaise traps
Ecological Entomology, Volume 51, Issue 3, Page 533-546, June 2026.Malaise traps sampled different communities during mornings (06:00–12:00), afternoons (12:00–16:00), evenings (18:00–22:00), and nights (22:00–06:00), highlighting the difference in diel rhythm between taxa. The highest diversity and abundance of insects were found during afternoons, the lowest diversity during night, and the lowest abundance during ...

Freshwater Biology, Volume 71, Issue 6, June 2026.ABSTRACT Headwaters often contribute disproportionately to network‐scale benthic biodiversity as differences in community composition between separate headwater streams (β‐diversity) can be high although local (α) diversity may be low. Most research on stream β‐diversity has adopted a spatial perspective, whereas temporal β‐diversity remains largely ...

Spatial and temporal distribution of adult aquatic insects.
, 2002 PhDMost quantitative ecological research on aquatic insects has addressed their immature stages. To understand their population dynamics, however, information on the adult stage is essential.
