The endangered freshwater pearl mussel Margaritifera margaritifera shows adaptation to a local salmonid host in Finland

open access: yesFreshwater Biology, Volume 67, Issue 5, Page 801-811, May 2022., 2022
Abstract The freshwater pearl mussel Margaritifera margaritifera (FPM) is an endangered unionid which has a glochidium larva that attaches to the gills of Atlantic salmon Salmo salar or brown trout S. trutta, although some FPM populations have been shown to exclusively attach to only one of these species.

Out of Their Shells: Digitisation of Endangered Diversity in Orphaned Collections Spurs Access and Discovery

open access: yesCurator: The Museum Journal, Volume 65, Issue 2, Page 355-378, April 2022., 2022
Abstract Natural history collections assembled before modern‐day, anthropogenic declines in species occurrence and abundance can provide essential data for conservation and biogeographic research. Digitizing old, commonly ‘orphaned’ collections in small institutions without professional curators increases local community access to specimens, as well as

The Impact of Exploitation on Freshwater Mussels (Bivalvia: Hyriidae) in the Tocantins River, Brazil [PDF]

open access: yesStudies on Neotropical Fauna and Environment, 2001
Freshwater mussels in the Tocantins River are exploited for their shells to make buttons. Data were collected on mussel density, size frequency distribution, habitat and exploitation level at five sites. The most abundant species is Paxyodon syrmatophorus (Meuschen, 1781) and is preferred by fishermen.

Gloquídio de Diplodon martensi (lhering) (Mollusca, Bivalvia, Hyriidae) e seu ciclo parasitário [PDF]

open access: yesRevista Brasileira de Zoologia, 1999
Conchological and anatomical studies of the glochidium of Diplodon martensi (lhering, 1893) were performed on samples collected in a small river, tributary from the Cai River, that belong to the Jacui River sub-basin in south-eastern Brazil. The parasitic development of the glochidium was observed in laboratory on a small cichlid fish Gymnogeophagus ...

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

open access: yesAquatic 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.

Extreme Hydrological Drought Threatens the Endemic Freshwater Mussel, Alathyria jacksoni Iredale, 1934, Northern Murray–Darling Basin, Australia

open access: yesAquatic 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.
