Patterns of DNA Barcode Variation in Canadian Marine Molluscs
BACKGROUND Molluscs are the most diverse marine phylum and this high diversity has resulted in considerable taxonomic problems. Because the number of species in Canadian oceans remains uncertain, there is a need to incorporate molecular methods into species identifications. A 648 base pair segment of the cytochrome c oxidase subunit I gene has proven useful for the identification and discovery ...
متن کاملLife History Traits and Population Processes in Marine Bivalve Molluscs
In this thesis, I investigated the how the life history characteristics of the clam Mya arenaria determine the population response to chronic contaminant exposure. To predict the potential responses of a broadcast-spawning life history such as that of M. arenaria, I surveyed the literature on a variety of bivalve species. By incorporating information on growth, survival, and reproduction into m...
متن کاملCalcification in marine molluscs: how costly is it?
Although crucial to our understanding of skeletal evolution in marine invertebrates, the cost of calcification has remained elusive for a simple reason: CaCO3 is an inorganic material. Its cost thus derives solely from the metabolic expenses of accumulating, transporting, and precipitating CaCO3 and cannot normally be separated from other metabolic costs. Traditionally, calcification cost has b...
متن کاملAntiproliferative Activity of Glycosaminoglycan-Like Polysaccharides Derived from Marine Molluscs
Despite the increasing availability of new classes of cancer treatment, such as immune- and targeted therapies, there remains a need for the development of new antiproliferative/cytotoxic drugs with improved pharmacological profiles that can also overcome drug resistant forms of cancer. In this study, we have identified, and characterised, a novel marine polysaccharide with the potential to be ...
متن کاملMolluscs
Figure 1. The ‘Kraken’ myth. Ancient tales repeatedly reported octopod-like sea-monsters attacking sea vessels. Indeed, octopuses may reach a maximum of 3 m body size, but the foundation of these ancient tales is based on giant squids (with ten rather than eight arms as depicted here) defending itself against its main predator, a sperm whale, rather than octopuses. Squids are known to leave suc...
