Novel Microsatellite Markers of Meretrix petechialis and Cross-species Amplification in Related Taxa (Bivalvia: Veneroida) [PDF]
International Journal of Molecular Sciences, 2012 The Asian hard clam, Meretrix petechialis, is an economically important bivalve, but its catch and population sizes are decreasing rapidly, owing to many factors, including large-scale reclamation of its natural habitat on the western coast of the Korean peninsula.

Spermatogenesis in the endosymbiont-bearing bivalveLoripes lucinalis (Veneroida: Lucinidae)
Molecular Reproduction and Development, 1996In the endosymbiont-bearing bivalve Loripes lucinalis, spermatogenesis is similar to that described for numerous bivalve species and leads to the formation of an aquasperm. The head and midpiece measure 10.5 +/- 1.5 microns in length. The head is made up of a cylindrical nucleus slightly tapered apically and capped by a short conical acrosome.

KARYOTYPE STUDY IN THE SURF CLAM MESODESMA DONACIUM LAMARCK, 1818 (BIVALVIA: VENEROIDA: MESODESMATIDAE) [PDF]
Gayana, 2008 Mesodesma donacium es un almeja distribuida desde Sechura Bay (5°S) en el Norte de Peru hasta la isla de Chiloe (43oS) en el sur de Chile. Debido a la importancia economica de esta especie, su poblacion ha sido reducida en los ultimos anos. En este trabajo se describe por primera vez la morfologia cariotipica de M.

Complete mitochondrial genome of the jackknife clamSolen grandis(Veneroida, Solenidae)
Mitochondrial DNA, 2012The complete mitochondrial genome sequence of Solen grandis that lives in sub-tidal waters and being buried in muddy to fine sand substrates, is described in this paper. The mitogenome (16,794 bp) consists of 12 protein-coding genes (loss of ATPase subunit 8), 22 tRNA genes, 2 rRNA genes and 1 putative control region.

Conservation Genetics Resources, 2012
The clam Lutraria sieboldii is a commercially important bivalve species, which has been suffering from severe population decline due to overexploitation. To evaluate its genetic diversity and structures of this clam, fourteen polymorphic microsatellites were firstly isolated and characterized. The number of alleles ranged from 2 to 16 per locus.

The xishishe clam Coelomactra antiquata is a commercially important bivalve species, but has been suffering from severe population decline due to over-exploitation and the deterioration of environmental conditions. To investigate the genetic variation and structures of this clam, nine polymorphic microsatellites were developed.

REGISTRO DE POLIPLOIDIA EN LA ALMEJA DULCEACUICOLA MUSCULIUM ARGENTINUM (D'ORBIGNY 1835) (SPHAERIIDAE, VENEROIDA) [PDF]
Gayana, 2005 La poliploidia es un caracter inusual en moluscos bivalvos. Sin embargo, datos citogeneticos documentados para especies de la subfamilia Sphaeriinae (familia Sphaeriidae) del hemisferio norte muestran numeros cromosomicos que varian desde 36 hasta ca. 247. La almeja dulceacuicola Musculium argentinum (D'Orbigny 1835) presenta un numero cromosomico 2n =
