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 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 کاملSaxitoxin analysis in bivalve molluscs
Paralytic shellfish poisoning (PSP) is caused by consumption of a wide variety of shellfish which accumulated saxitoxins (STXs) from marine dinoflagellates (Alexandrium minutum, A. tamarense, Gymnodinium catenatum, Pyrodinium bahamense) and affect a wide variety of shellfish. There are about 20 saxitoxin analogs with closely related structures. A regulatory level of 0.8 mg/kg shellfish meat as ...
متن کاملDomoic acid analysis in bivalve molluscs
Domoic acid (DA) was identified as the toxin responsible for an outbreak of illness in Canada in 1987, caused by eating blue mussels that had accumulated DA as a result of the presence of Pseudo-nitzschia pungens. It is named amnesic shellfish poisoning (ASP). Since a regulatory level of 20 mg DA/kg of shellfish meat was established. The methods of determination of domoic acid are reviewed: bio...
متن کاملSpecies composition, richness, and distribution of marine bivalve molluscs in Bahía de Mazatlán, México
We describe the composition and distribution of bivalve molluscs from the sandy and rocky intertidal and the shallow subtidal environments of Bahía de Mazatlán, México. The bivalve fauna of the bay is represented by 89 living species in 28 families, including 37 new records and four range extensions: Lithophaga hastasia, Adula soleniformis, Mactrellona subalata, and Strigilla ervilia. The numbe...
