Life 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 کاملPatterns 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 کاملTerpenoids from the Marine-Derived Fungus Aspergillus fumigatus YK-7.
Two new β-bergamotane sesquiterpenoids, E-β-trans-5,8,11-trihydroxybergamot-9-ene (1) and β-trans-2β,5,15-trihydroxybergamot-10-ene (2), were isolated from the marine-derived fungus Aspergillus fumigatus YK-7, along with three known terpenoids 3-5. Their structures were determined by spectroscopic methods (1D and 2D NMR, HR-ESI-MS). Antiproliferative effects on human leukemic monocyte lymphoma ...
متن کاملNew Naphthoquinone Terpenoids from Marine Actinobacterium, Streptomyces sp. CNQ-509
A member of the marine streptomycete clade MAR4, Streptomyces sp. CNQ-509, has genetic potential for the biosynthesis of hybrid isoprenoids and produces several meroterpenoids such as naphterpin, nitropyrrolin and marinophenazine. Our research on the strain CNQ-509 led to the isolation of two new naphterpin derivatives (1 and 2) comprised of naphthoquinone and geranyl moieties along with the kn...
