Bivalve genomics
Interest in bivalve genomics has emerged during the last decade, owing to the importance of these organisms in aquaculture and fisheries and to their role in marine environmental science. Knowledge of bivalve genome structure, function and evolution resulting from 20th century “single gene” approaches is limited, but genomic technologies are called to dramatically increase it. Research based on...
متن کاملA molecular phylogeny of the bivalve mollusks.
A phylogenetic reconstruction based on 506 nucleotides near the 5' end of the 18S subunit of ribosomal DNA (rDNA) in 2 gastropod, 3 chiton and 28 bivalve mollusks supported the monophyly and sister group relationship of the subclasses Heterodonta and Palaeoheterodonta but could not confidently establish either the monophyly or the phylogenetic relationships of the morphologically well defined s...
متن کاملViruses infecting bivalve molluscs
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...
متن کاملSpawning & Rearing Bivalve Mollusks:
In this lesson, students will acquire skills in using an ocular micrometer to measure the length of bivalve larvae, monitor the density of larvae in their culture system, and understand production protocols used in bivalve hatcheries. This activity will take a period from each class over approximately a two-week period – the time for larvae to develop from egg to metamorphosis (setting). One or...
متن کاملSpawning & Rearing Bivalve Mollusks:
In this lesson, students will learn methods for spawning bivalve mollusks (e.g. clams or oysters) using thermal induction. Students will acquire skills in using an ocular micrometer to measure the diameter of bivalve eggs and the length of bivalve larvae. The following lesson plan will have students monitoring the density of larvae in their culture system and understanding production protocols ...
