Gametophytes of E. radiata (C.Ag.)J.Ag. grew in culture at 15 degree C under daily quantum doses ranging from 0.86 to 360 cE m super(-2). Growth rates increased with quantum doses up to 40 cE m super(-2) d super(-1), then reproduction began and the relative growth constant declined while ovum releas...

Interviews with government staff responsible for fisheries management in Maluku, Indonesia in 1997-98 revealed problems in capacity, and an emphasis on economic development rather than management. The traditional institutions which persisted in some villages to regulate the access and withdrawal rig...

Since the first sublittoral survey off Lawrencetown, Nova Scotia in 1965--66 there has been a cycle of dominance by herbivorous sea urchins followed by mortality of these animals because of disease in 1981 and regrowth of algae. A survey of the same site in 1984 revealed that the algal communities p...

Growing and cast leaves of Zostera marina were sampled from May through December and in February in two embayments of the southern Gulf of St. Lawrence to determine the species composition and temporal pattern of macroalgal epiphytes. Thirty-eight species were identified. Some occurred sporadically ...

Domoic acid is a neurotoxic amino acid responsible for an outbreak of human food poisoning in late 1987 following consumption of contaminated blue mussels (Mytilus edulis L.) from eastern Prince Edward Island, Canada. In vitro techniques were used to examine the uptake of domoic acid by digestive gl...

Glutamic acid (GA) and kainic acid (KA) are structurally related to domoic acid (DOM), a neurotoxic amino acid that caused human food poisoning in 1987, following consumption of toxic mussels (Mytilus edulis ) from Prince Edward Island, Canada. To study the difference in response of mussels to a phy...

The morphogenetic responses to temperature and photoperiod of plants from Nova Scotia, Canada belonging to the Scytosiphon lomentaria complex were evaluated. Formation of erect thalli by clonal isolates of S. lomentaria var. complanatus was controlled by temperature, and independent of daylength.
