Estado actual de la taxonomía de bivalvos dulceacuícolas chilenos: progresos y conflictos

Revista Chilena de Historia Natural, 2002
Se presenta una revisión actualizada de la taxonomía de los bivalvos dulceacuícolas chilenos. Los bivalvos descritos a la fecha, están adscritos a dos familias: Hyriidae representada sólo por el género Diplodon con dos especies (D.

Description and potential sources of a shell deformity in North American freshwater mussels (Unionoida). [PDF]

J Aquat Anim Health
Abstract Objective Freshwater mussels of the order Unionoida are among the most imperiled taxa in North America, and many species are undergoing enigmatic decline without fully understood causation. Disease pathology and parasitology have been identified as areas with significant knowledge gaps in relation to these declines.

DIPLODON CF. COLHUAPIENSIS (BIVALVIA, HYRIIDAE) IN THE SANTA CRUZ FORMATION (EARLY–MIDDLE MIOCENE) AT THE RÍO SANTA CRUZ, PATAGONIA, ARGENTINA. STRATIGRAPHIC AND PALEOENVIRONMENTAL CONSIDERATIONS [PDF]

Publicación Electrónica de la Asociación Paleontológica Argentina, 2019
The Santa Cruz Formation (Early–Middle Miocene) is one of the most widespread sedimentary units of the Argentine Patagonia. This unit contains an abundant and taxonomically diverse fossil vertebrate fauna, especially in mammals. Thus, the paleoecological

Surviving global change: a review of the impacts of drought and dewatering on freshwater mussels. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT The increase in the frequency and intensity of droughts and heatwaves caused by climate change poses a major threat to biodiversity. In aquatic systems, sedentary species such as freshwater mussels are generally considered more vulnerable to changes in habitat conditions than mobile species such as fish.

A novel assembly pipeline and functional annotations for targeted sequencing: A case study on the globally threatened Margaritiferidae (Bivalvia: Unionida)

Molecular Ecology Resources, Volume 23, Issue 6, Page 1403-1422, August 2023., 2023
Abstract The proliferation of genomic sequencing approaches has significantly impacted the field of phylogenetics. Target capture approaches provide a cost‐effective, fast and easily applied strategy for phylogenetic inference of non‐model organisms.

Effect of suspended sediment concentration on the clearance and biodeposition rates of an Australian freshwater mussel (Hyriidae: Alathyria jacksoni)

Freshwater Biology, Volume 68, Issue 8, Page 1413-1427, August 2023., 2023
Abstract Freshwater mussels are an ancient group of molluscs that are considered ecosystem engineers because of the many important functions they perform, including biofiltration and biodeposition. Associations between mussel declines and increased sedimentation are well documented, but the direct effects of suspended sediment (SS) concentrations on ...

Development of a flow‐sensitive macroinvertebrate index for Australian rivers

River Research and Applications, Volume 38, Issue 5, Page 846-862, June 2022., 2022
Abstract Hydrologically sensitive macroinvertebrate indices have been developed in Europe, the Americas and New Zealand to serve many purposes such as monitoring ecological responses to drought, flow regulation, water extraction and the provision of environmental flows.

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

Freshwater 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

Curator: 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

ANTECEDENTES ARQUEOLÓGICOS DEL GENERO DIPLODON (SPIX, 1827) (BIVALVIA, HYRIIDAE) EN CHILE [PDF]

Gayana (Concepción), 2008
Se presenta una revision bibliografica de los registros del genero Diplodon (Spix, 1827) (Hyriidae), presentes en sitios arqueologicos de Chile. Las evidencias indican una efimera presencia de estos bivalvos en contextos arqueologicos de finales del Pleistoceno, mientras que durante gran parte del Holoceno su registro es mas significativo. No obstante,
