The South-American distribution and southernmost record of Biomphalaria peregrina—a potential intermediate host of schistosomiasis [PDF]

PeerJ, 2017
Schistosomiasis remains a major parasitic disease, endemic in large parts of South America. Five neotropical species of Biomphalaria have been found to act as intermediate hosts of Schistosoma mansoni in natural populations, while others have been shown ...

Evidences That Host Genetic Background More Than the Environment Shapes the Microbiota of the Snail Bulinus truncatus, an Intermediate Host of Schistosoma Species

Molecular Ecology, Volume 35, Issue 6, March 2026.
ABSTRACT Microbiota have emerged as fundamental regulators of host physiology, shaping both ecological interactions and evolutionary trajectories. Yet, the determinants of microbiota diversity and structure in wild populations—particularly the respective roles of host genetics and environmental context—are still poorly understood.

Effects of Lateral Hydrological Connectivity on Aquatic Invertebrate Assemblages in Floodplains, Oxbow Lakes and the Main River Channel of the Savannah River, Southeastern USA

Freshwater Biology, Volume 71, Issue 2, February 2026.
ABSTRACT Within river corridors, hydrological connectivity drives the local abiotic and biotic processes, shapes ecosystem functioning and promotes biodiversity. However, hydrological cycling is changing due to climate change, and drought is intensifying and becoming more frequent in many regions of the world, making it critical to understand the ...

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.

Influence of Fluvial Structure on Benthic Macroinvertebrates in a Restored Meandering River, Geul Basin, Netherlands

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT Benthic macroinvertebrates are indicators of water quality and riparian ecosystem health. Their abundance and distribution in streams are associated with river basin environmental factors, including stream biotic and abiotic fluvial processes. We examined benthic macroinvertebrate diversity and abundance in relation to large wood (LW) and pool‐

Invasive Eurasian Minnow Alters the Trophic Niche and Growth of Brown Trout in High‐Latitude Lakes

Ecology of Freshwater Fish, Volume 35, Issue 1, January 2026.
ABSTRACT Invasive species pose a major threat to aquatic ecosystems, particularly in high‐latitude lakes which are characterised by low biodiversity. In northern Europe, the Eurasian minnow (Phoxinus phoxinus) has colonised lakes historically dominated by salmonids, raising concerns about the impacts of invasive cyprinids on native fish populations and
