Geographic variations in shell growth rates of the mussel Diplodon chilensis from temperate lakes of Chile: Implications for biodiversity conservation

open access: yesLimnologica, 2007
AbstractThe Chilean lake district includes diverse lentic ecosystems along ca. 700km of the country (36°–43°S), including the “Nahuelbutan lakes”, “Araucanian lakes” and “Chiloe lakes”. This area is recognized as an important “hot spot” of benthic freshwater biodiversity in Southern South America. In Chilean temperate lakes, increased nutrient loads of

Biomarker responses to sewage pollution in freshwater mussels ( Diplodon chilensis ) transplanted to a Patagonian river [PDF]

open access: yesJournal of Environmental Science and Health, Part A, 2014
Field and laboratory experiments were combined to evaluate biomarker responses of Diplodon chilensis to sewage pollution. Mussels from an unpolluted area in Lacar lake (S0) were caged at a reference site (S1) and at two sites with increasing sewage pollution (S2, S3) in Pocahullo river (all in Argentina).

Does shell shape variation play a role in conservation of the long‐lived freshwater bivalve Diplodon chilensis (Bivalvia, Hyriidae)? [PDF]

open access: yesEcohydrology, 2017
AbstractFreshwater bivalves of the order Unionoida display an uncommon phenotypic plasticity with high interpopulation and intrapopulation morphological variability, which could be advantageous for coping with habitat modifications. However, unionoids have suffered a marked population decline in different parts of the world in the last decades.
