Understanding how microsatellites are distributed in eukaryotic genomes is important to clarify the differential abundance of these repeats under an evolutionary scenario. We have concatenated data from 3165 DNA sequences of 326 Bivalvia species to search for taxonomic patterns of microsatellite distribution in genomic regions of markedly different functionality. Some microsatellite motifs in b...

Bivalve molluscs are filter feeders and as a consequence they may bioaccumulate in their tissues viruses that infect humans and higher vertebrates. However, there have also been described mortalities of bivalve molluscs associated with viruses belonging to different families. Mass mortalities of adult Portuguese oysters, Crassostrea angulata, among French livestocks (between 1967 and 1973) were...

A long-term time series of plankton and benthic records in the North Sea indicates an increase in decapods and a decline in their prey species that include bivalves and flatfish recruits. Here, we show that in the southern North Sea the proportion of decapods to bivalves doubled following a temperature-driven, abrupt ecosystem shift during the 1980s. Analysis of decapod larvae in the plankton r...

Elak elak beach has a sea and coast with substrate texture that is very suitable as habitat for Mollusca including bivalves. Bivalves have many roles the environment, especially in providing food various other species chain can be used to determine water quality. This study aims community structure distribution pattern of bivalves Beach see student responses booklets. The method this research l...

Formation of nacre (mother-of-pearl) is a biomineralization process of fundamental scientific as well as industrial importance. However, the dynamics of the formation process is still not understood. Here, we use scanning electron microscopy and high spatial resolution ion microprobe depth-profiling to image the full three-dimensional distribution of organic materials around individual tablets ...
