Seasonal periodicity of growth and composition in valves of Diplodon chilensis patagonicus (d'Orbigny, 1835) [PDF]
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 ...

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%

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).

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.

Estudo de Diplodon (Diplodon) multistriatus (Lea, 1831) encontrado no Estado do Rio de Janeiro, Brasil (Molluscca, Bivalvia, Hyriidae) [PDF]
Diplodon (Diplodon) multistriatus (Lea, 1831) from the State of Rio de Janeiro, Brazil, was investigated. The studies undertaken were related to aspects of the taxonomy, morphology of the shell, and structures of the soft parts when relevant.

Detailed sedimentologic, petrographic and geochemical analyses of the lacustrine deposits registered on the Ñirihuau Formation middle section in the northern sector of the Ñirihuau Basin are presented. The lacustrine carbonates found within these deposits were analysed to characterise the palaeolake system as well as the carbonate factory of the basin,

Hysterothylacium larvae (Nematoda, Anisakidae) in the freshwater mussel Diplodon suavidicus (Lea, 1856) (Mollusca, Unioniformes, Hyriidae) in Aripuanã River, Amazon, Brazil [PDF]
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 ...

Microestructura y polimorfismo en valvas recientes de Diplodon chilensis patagonicus (dOrbigny 1835) [PDF]
Gracias a su potencial como registro ambiental, las valvas del molusco Diplodon han despertado recientemente el interes de la comunidad cientifca. En este trabajo, por medio de microscopia electronica de barrido (SEM) y espectroscopia Raman se investigo la microestructura y el polimorfsmo en valvas recientes de Diplodon chilensis patagonicus.
