Distribution, scale, and drivers of mass mortality events in Europe's freshwater bivalves
Conservation Biology, EarlyView.Abstract Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa.

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.Our results suggest that pressures in marine ecosystems often arise from numerous seemingly minor activities that collectively contribute to substantial habitat degradation. They underscore the urgent need to develop more targeted, local management measures that address detrimental small‐scale activities.

The Journal of Wildlife Management, Volume 89, Issue 8, November 2025.We compared survivorship, in a hatchery (control) and silos in natural streams, of juvenile Carolina heelsplitter originating from two geographically isolated river basins (Pee Dee River basin, Catawba River basin) over 1 year (Oct 2021–Oct 2022) and survivorship of a second species (eastern creekshell) to evaluate its potential use as a surrogate for ...

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 10, October 2025.ABSTRACT Freshwater mussels are ecosystem engineers: They modify substrates through burrowing, mediate water quality through filtration, provide food and habitat for other organisms and play a substantial role in the biogeochemical cycling of nutrients; they are also seriously threatened globally.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 8, August 2025.ABSTRACT Freshwater mussels are globally threatened due to changes in the hydrological cycle and water quality. The Rio Grande basin in North America contains the endangered unionid Popenaias popeii (Texas hornshell). Secondary salinisation has likely contributed to the decline of this species, leaving only a handful of populations remaining ...

Size Matters: Effects of Propagule Size on Dispersal in Rivers
Water Resources Research, Volume 61, Issue 8, August 2025.Abstract Biological particles (e.g., bacteria, eggs, fruit/seeds and larvae) of a wide range of sizes (i.e., 10−6–10−1 m) are transported over various distances (i.e., 100–104 m) downstream in rivers. We examined the effects of propagule size on downstream dispersal by releasing biodegradable microbeads (density ∼ 1,200 kg m−3) of three size classes ...

Environmental DNA Detects Endangered Texas Hornshell and Its Hosts
Ecology and Evolution, Volume 15, Issue 7, July 2025.ABSTRACT Environmental DNA techniques are continuously demonstrating their efficiencies over traditional survey methods for detecting rare species. Unionids have a need for focused conservation efforts as they represent some of the most imperiled aquatic species in North America.

Mitochondrial DNA. Part B. Resources, 2019 We have sequenced the female type (F-type) mitochondrial genome of Nodularia douglasiae (Unioninae, Unionidae, Unionida, Bivalvia) from Lake Kasumigaura, Japan, and inferred the Unioninae phylogeny using complete mitochondrial genome sequences.

Unexpected Shifts in Bivalve Function From Filtration to Transmission Risk
Freshwater Biology, Volume 70, Issue 6, June 2025.ABSTRACT Understanding the complex interactions between filter‐feeding species and zoonotic disease transmission in aquatic environments is crucial for accurately quantifying the ecosystem services provided by these organisms. This study explores for the first time the roles of freshwater bivalves in the transmission dynamics of emerging zoonotic ...

The complete mitochondrial genome of a freshwater mussel Nodularia douglasiae (Bivalvia: Unionidae)
Mitochondrial DNA. Part B. Resources, 2018 The circular F-type mitochondrial genome (15,761 bp) was completely sequenced for a Korean freshwater mussel Nodularia douglasiae (synonym Unio douglasiae; Unionidae, Unionida, Bivalvia).
