New Zealand Recent Hyriidae (Mollusca: Bivalvia: Unionida)
Molluscan Research, 2014The New Zealand freshwater mussels are taxonomically revised and compared with key Australian and South American taxa using DNA sequence data. Three living species are recognised: Echyridella menziesii, Echyridella aucklandica and Echyridella onekaka. Cucumerunio websteri websteri and Cucumerunio websteri delli, are treated as junior synonyms of Unio ...

Hysterothylacium larvae (Nematoda, Anisakidae) in the freshwater mussel Diplodon suavidicus (Lea, 1856) (Mollusca, Unioniformes, Hyriidae) in Aripuanã River, Amazon, Brazil [PDF]
Journal of Invertebrate Pathology, 2011 Larvae of Hysterothylacium use various invertebrates as intermediate hosts. Definite hosts include fish, birds, reptiles or marine mammals. This study describes the occurrence of Hysterothylacium (Nematoda, Anisakidae) larvae parasitizing the pericardic ...

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

Aquatic Conservation: Marine and Freshwater Ecosystems, 2017
Abstract Freshwater mussels provide important benefits to aquatic ecosystems by filtering water, bioturbating sediments, and cycling and transforming nutrients. The global decline in mussel diversity, distribution and abundance has led to concerns that ecological functioning in freshwater systems will be diminished.

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

International Review of Hydrobiology, 2021
AbstractBivalves can consume detritus, bacteria, phytoplankton, and zooplankton by filtering the water column. Ecological attributes like filtration rate (FR) and excretion rate (ER) are particularly important to better understand the role of bivalves in ecosystem.

Caracterización metabólica de Diplodon chilensis (Gray, 1828) (Bivalvia: Hyriidae) expuesto a anoxia experimental [PDF]
Revista De Biologia Marina Y Oceanografia, 2008 Diplodon chilensis es un bivalvo dulceacuicola que habita desde el norte de Chile hasta Tierra del Fuego, posee una alta capacidad de filtracion y gran tolerancia a ambientes hipoxicos. Por esta razon, el objetivo de este estudio fue caracterizar por primera vez el metabolismo anaerobico de D.

Malacologia, 2006 Freshwater mussels are an important component of the aquatic biodiversity of Chile, especially in the southern part of the country, and other geographical areas of the northern and southern hemispheres. The most common species in Chile is Diplodon chilensis (Gray, 1828), which is a unique species of Hyriidae with a distribution extending from 34°58’S ...

ABSTRACTGonadal cycles are described for Alathyria jacksoni and Velesunio ambiguus from the River Murray at Overland Corner (near Lock 3) and for V. ambiguus at Point Sturt, Lake Alexandrina. The study included periods of low flow (1982), minor flooding (1983) and intermediate flow (1986). In males, gametogenesis continued year-round with fertilisation

Shape variation in the Australian freshwater mussel Alathyria jacksoni Iredale (Bivalvia, Hyriidae)
Hydrobiologia, 1991Different forms of the hydriid mussel Alathyria jacksoni occur in riverine habitats of the Murray-Darling river system, south-eastern Australia. Electrophoretic data for three enzymes (glucose phosphate isomerase, malate dehydrogenase and malic enzyme) support the assumption that these are morphological variants of one species.
