Potential causes for the stranding of Macrohectopus branickii (Dybowsky, 1874) specimens along the Angara River: strong currents, artificial lighting, or ice melting

open access: yesActa Biologica Sibirica
Macrohectopus branickii (Dybowsky, 1874) is the world's only freshwater pelagic amphipod native to Lake Baikal. The habitat of this amphipod is limited to the pelagic zone of Lake Baikal (with periodic nocturnal migrations to the littoral part of the ...

Patterns of Evolutionary Diversification in a World‐Significant Hotspot of Salmonid Diversity: A Study of Landlocked Salvelinus Fish of the Kronotskoe‐Uzon Area, Kamchatka

open access: yesEcology and Evolution, Volume 16, Issue 9, September 2026.
We have examined the phylogenetic relationships, genomic structure, admixture, and historical gene flow among the endemic charrs from the Kronotskoe‐Uzon water system in Kamchatka, in order to reconstruct their evolutionary history. We found that this unique diversity formed in the post‐LGM—Holocene time as a result of several waves of Salvelinus malma

Climatic niche divergence and high‐elevation adaptation promoted rapid diversification of Pimoa spiders in Pan‐Himalaya

open access: yesEcography, Volume 2026, Issue 9, September 2026.
The Pan‐Himalayan region harbors exceptional biodiversity, yet the origins and underlying mechanisms driving this remarkable diversity remain poorly understood, especially among species‐rich invertebrates. Pimoa spiders exhibit an intercontinental disjunct distribution across three major mountain regions: the Rockies, the Alps, and the Pan‐Himalaya ...

Terrestrial Amphipods or "Lawn Shrimp," (Crustacea: Amphipoda)

open access: yes, 2004
Amphipods comprise an order of crustacea, shrimp-like in form, which contains mostly marine and freshwater forms. While some species are terrestrial, they still require moist habitats.

Oyster reef habitat characteristics and nekton communities vary with restoration method in a large‐scale project

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Restoration in coastal ecosystems is revitalizing populations of foundation species that provide valuable habitat to support biodiversity and ecosystem services. The goals of oyster reef restoration include increasing oyster populations and oyster reef ecosystem services such as provision of habitat for commercially and ecologically valuable ...

Seasonal Variation and Feeding Habits of Amphipods Inhabiting Zostera marina Beds in Gwangyang Bay, Korea

open access: yes, 2004
On the basis of monthly samples, we investigated the seasonal variation and feeding habits of amphipods inhabiting Zostera marina beds in Gwangyang Bay. Dominant species (>1% of the total number of amphipods) consist of 5 gammarids (Gammaropsis japonicus,

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. Graphical abstract image created in BioRender. Watanabe, K. (2026) https://BioRender.com/khqac0n.

Diet and Prey Selection of Migratory Shorebirds on Virginia Mudflats Revealed by Fecal DNA Metabarcoding

open access: yesEnvironmental DNA, Volume 8, Issue 5, September‐October 2026.
Fecal DNA metabarcoding revealed species‐specific diets of migratory shorebirds on Virginia mudflats, highlighting mudflats as diverse foraging habitats and uncovering a previously undocumented biofilm pathway in mid‐Atlantic shorebird food webs.

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.
