Using Natural History Collections to Determine the Relative Changes in Diversity and Distribution of Freshwater Molluscs in KwaZulu‐Natal, South Africa

African Journal of Ecology, Volume 64, Issue 2, March 2026.
ABSTRACT Research using natural history collections to track anthropogenic activities has recently been on the rise. Natural history collections have been utilised beyond their traditional taxonomic and systematic roles, generating data that shape present and future research.

Habitat Structure Shapes Mollusc Assemblages in an Urban Semiarid River: Implications for Conservation and Public Health

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
ABSTRACT Fine‐scale environmental drivers shape freshwater mollusc assemblages in urban semiarid rivers. We examined how substrate composition and water chemistry influence mollusc richness and abundance along a polluted stretch of a river in the Brazilian semiarid region. Surveys at five sites recorded 2479 individuals.

Macroinvertebrate communities associated with littoral zone habitats and the influence of environmental factors in Malilangwe Reservoir, Zimbabwe

Knowledge and Management of Aquatic Ecosystems, 2012
The aim of our study was to investigate macroinvertebrate communities so as to understand factors and processes structuring macroinvertebrate communities in a small reservoir, Malilangwe reservoir over seven months (April to October).

A Contribution Toward Understanding Trematode Diversity in Freshwater Snails of the Southwestern Kathmandu Valley, Nepal

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Background Freshwater snails serve as intermediate hosts for trematode parasites and play a key role in transmitting various parasitic diseases. Snail‐borne trematodiases pose important public and veterinary health risks in South Asia, where freshwater snails sustain transmission in agricultural and periurban waters.

Assessing the Relationship Between Macroinvertebrate Metrics and Fine Sediment Index for Ecological Biomonitoring in the Little Akaki River, Addis Ababa, Ethiopia

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Habitat quality had a positive correlation with percentage of Ephemeroptera, percentage of EOT, and Shannon diversity index (r = 0.833, r = 0.880, and r = 0.939, respectively). PSI had positive correlation with number of taxa, and ASPT‐ETHbios (r = 0.819, and r = 0.798, respectively). Most sites were heavily sedimented.

Removing invasive stream macrofauna shifts nontarget invertebrate mesofauna through facilitation

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Positive interactions among non‐native species can drive invasional meltdowns to the detriment of native biota. Here, we assessed whether targeted control of aquatic invasive species (AIS) can benefit native species by eliminating synergies among invaders.

The most cosmopolitan freshwater gastropod invades the Lower São Francisco River: first record of Physella acuta in Sergipe

Biota Colombiana
Biological invasion and habitat modification are major drivers of biodiversity loss. River damming, in particular, leads to hydrological, limnological, and habitat disruptions, and facilitates the introduction, establishment and spread of alien species.

Discharge and nutrients interact to determine trophic structure in a wetland: Evidence from a landscape‐scale manipulation

Limnology and Oceanography, Volume 70, Issue 11, Page 3355-3369, November 2025.
Abstract Identifying drivers of consumer biomass patterns and community structure is complex for managed freshwater ecosystems that are sensitive to nutrients and drought. In the Florida Everglades, flow restoration is expected to reintroduce discharge across an expansive wetland, yet most research on consumers has focused on water depth and dry ...
