Assessment of Hyporheic Macroinvertebrate Biodiversity Within Gravel Bars Before and After Flooding: Comparison of Morphology, Bulk‐Sample, and eDNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 5, September‐October 2026.
eDNA metabarcoding is generally consistent with morphology and bulk‐sample metabarcoding in revealing changes in hyporheic macroinvertebrate biodiversity influenced by flood and lateral locations of hyporheic zones.

Complementary but Not Interchangeable: A Comparison of eDNA and Bulk Sample Metabarcoding for the Assessment of Groundwater Invertebrate Communities

open access: yesEnvironmental DNA, Volume 8, Issue 5, September‐October 2026.
Bulk‐ and eDNA‐metabarcoding were compared across 50 groundwater sites (monitoring wells, springs, hydrants) to assess invertebrate communities. Both recovered different community structures with limited overlap (13.8% OTUs); eDNA was dominated by non‐stygobionts, and bulk samples by stygobionts.

Effects of a Catastrophic Debris‐Flow on a Coastal Salt Marsh

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Debris‐flows are extreme events that can occur when wildfire is followed by heavy precipitation. Although debris‐flow effects are primarily assessed in montane systems, here, we document the downstream physical and biological impacts of a debris‐flow in a coastal salt marsh.

Climate Warming Promotes Carbon Sequestration and Weathering in Tundra Landscapes and Alters Carbon Chemistry of Subarctic Lakes in Scandinavia

open access: yesGlobal Change Biology Communications, Volume 1, Issue 3, September 2026.
Climate‐induced vegetation greening (NDVImax) stimulated C‐sequestration in subarctic catchments by 10%–85% during the last decades. Increases in weathering and declines in non‐marine SO4 atmospheric deposits were identified as the main drivers of decadal increases in inorganic C (ICalk) run‐off to subarctic lakes.

Macroinvertebrates in the bed sediment of the Yellow River

open access: yes, 2011
Extensive agricultural, industrial and urban development in the Yellow River, China, have modified the sediment-water balance, flow and inundation regimes, longitudinal connectivity, integrity of riparian vegetation, and water quality.

Threats and Shifts in Microbial Communities of Salars Associated With Direct Lithium Extraction and Brine Reinjection

open access: yesGlobal Challenges, Volume 10, Issue 9, September 2026.
Lithium for rechargeable batteries is increasingly extracted from brines in high‐Andean salars. Direct Lithium Extraction (DLE) technologies are promoted as sustainable alternatives to conventional evaporation ponds. This work explores how brine modification and reinjection may affect microbial communities and ecosystem functioning, highlighting the ...

Changes in the benthic macroinvertebrates in Xiangxi Bay following dam closure to form the Three Gorges Reservoir

open access: yes, 2006
Benthic macroinvertebrates were assessed monthly in Xiangxi Bay of the Three Gorges Reservoir for two years after the initial closure of the dam. Mean total density of macroinvertebrates varied from 275 ind./m(2) during the first year to 5,094 ind./m(2 ...

Macroinvertebrates as indicators of pollution.

open access: yesJournal of environmental biology, 2005
Various pollution indicators of stream Ban-Ganga have been identified on the basis of presence/absence/numerical abundance at various stations. They have been categorized as pollution tolerant, facultative and pollution intolerant groups in relation with the water quality at different stations of stream.
