Manganese speciation inDiplodon chilensis patagonicusshells: a XANES study
Journal of Synchrotron Radiation, 2010 X-ray absorption near-edge spectroscopy (XANES) at the Mn K-edge was used to investigate the environment of Mn in situ within the growth increments of the long-lived freshwater bivalve species Diplodon chilensis patagonicus. Single XANES spectra and Mn Kalpha fluorescence distributions were acquired at submillimetre resolution (up to 100 microm x 50 ...

Seasonal periodicity of growth and composition in valves of Diplodon chilensis patagonicus (d'Orbigny, 1835) [PDF]
Journal of Molluscan Studies, 2008 Freshwater mussels of the genus Diplodon (Unionida) are common inhabitants of lakes and rivers in South America, and have slow growth and long life spans. We established the annual periodicity of incremental shell growth in Diplodon chilensis patagonicus (d'Orbigny, 1835) and calculated growth rates at different ages, using internal ring counting ...

Substrate selection by the freshwater mussel Diplodon chilensis (Gray, 1828): field and laboratory experiments [PDF]
Journal of Molluscan Studies, 2009 To evaluate the capacity for movement of freshwater mussels in sandy and sand-gravel substrates and to test their ability to differentiate among types and qualities of substrates, experiments were carried out in the laboratory and in the field, using Diplodon chilensis from Lake Panguipulli, Chile.

Journal 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).

Variabilidad genética local del bivalvo dulceacuícola Diplodon chilensis (Gray 1828) proveniente de tres lagos Nahuelbutanos [PDF]
Gayana (Concepción), 2010 Se describe la variabilidad genetica del bivalvo dulceacuicola Diplodon chilensis proveniente de tres lagos Nahuelbutanos, cada uno de los cuales presenta barreras geograficas y diferencias ambientales reconocibles como consecuencia de diversos eventos geomorfologicos y antropicos.

Ecotoxicology and Environmental Safety, 2020 An in-situ experiment was performed to study metabolic responses of the freshwater mussel Diplodon chilensis to water contaminated by leachates from an open dump and cattle activity, in order to analyze both the effects of those contaminants on aquatic environments and the potential use of a native bivalve to evaluate the effects of anthropic influence

Marine Pollution Bulletin, 2014 Lipid and fatty acid (FA) composition and selected oxidative stress parameters of freshwater clams (Dipolodon chilensis), from a sewage-polluted (SMA) and a clean site, were compared. Trophic markers FA were analyzed in clams and sediment. Saturated FA (SAFA), and bacteria and sewage markers were abundant in SMA sediments, while diatom markers were 50%

Does shell shape variation play a role in conservation of the long‐lived freshwater bivalve
Ecohydrology, 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.

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2011 The aim of this work was to study the oxidative stress effects and histological alterations caused by dietary copper on the filter-feeding freshwater mussel Diplodon chilensis. Bivalves were fed during 6 weeks with the green algae Scenedesmus vacuolatus previously exposed to copper.
