Marine pollution detection through biomarkers in marine bivalves
Indian coastal waters are subjected to considerable pressure from sewage and industrial wastes, which are responsible for the contamination of the waters with consequent loss in biodiversity. Monitoring methods adopted so far have helped in documenting the level of contaminants in water, sediments and biota, but not the interaction of these pollutants with living organisms. Exposure of animals ...
متن کاملPhylogenetic conservatism of extinctions in marine bivalves.
Evolutionary histories of species and lineages can influence their vulnerabilities to extinction, but the importance of this effect remains poorly explored for extinctions in the geologic past. When analyzed using a standardized taxonomy within a phylogenetic framework, extinction rates of marine bivalves estimated from the fossil record for the last approximately 200 million years show conserv...
متن کاملThe miRNA biogenesis in marine bivalves
Small non-coding RNAs include powerful regulators of gene expression, transposon mobility and virus activity. Among the various categories, mature microRNAs (miRNAs) guide the translational repression and decay of several targeted mRNAs. The biogenesis of miRNAs depends on few gene products, essentially conserved from basal to higher metazoans, whose protein domains allow specific interactions ...
متن کاملIndependent phylogenetic origins of methanotrophic and chemoautotrophic bacterial endosymbioses in marine bivalves.
The discovery of bacterium-bivalve symbioses capable of utilizing methane as a carbon and energy source indicates that the endosymbionts of hydrothermal vent and cold seep bivalves are not restricted to sulfur-oxidizing chemoautotrophic bacteria but also include methanotrophic bacteria. The phylogenetic origin of methanotrophic endosymbionts and their relationship to known symbiotic and free-li...
متن کاملImmune responses to infectious diseases in bivalves.
Many species of bivalve mollusks (phylum Mollusca, class Bivalvia) are important in fisheries and aquaculture, whilst others are critical to ecosystem structure and function. These crucial roles mean that considerable attention has been paid to the immune responses of bivalves such as oysters, clams and mussels against infectious diseases that can threaten the viability of entire populations. A...
