Selection and population genetic structure of the barnacle Semibalanus balanoides in the northwest Atlantic and Gulf of St. Lawrence*
It has been proposed that population genetic structure at the mannose-6-phosphate isomerase (Mpi) locus in the barnacle Semibalanus balanoides (L.) could be due to selection by ice scour acting through variation in larval settlement behavior. Homogeneity of Mpi allele frequencies for barnacles within the Gulf of St. Lawrence could be maintained by a combination of selection and limited gene flo...
متن کاملImpact of ultraviolet radiation on marine crustacean zooplankton and ichthyoplankton: a synthesis of results from the estuary and Gulf of St. Lawrence, Canada
The objectives of the research program reported upon here were (1) to measure ambient levels of UV radiation and determine whichvariables most strongly affected its attenuation in the waters of the estuary and Gulf of St. Lawrence, Canada; and (2) to investigate the potential direct impacts of W radiation on species of crustacean zooplankton and fish whose early life stages are planktonic. In t...
متن کاملEvolution of growth in Gulf of St Lawrence cod?
Fishing is often size selective such that the likelihood of capture increases with body size. It has therefore been postulated that fishing could favour evolution of slower growth because smaller size would reduce exposure to fishing gear (e.g. Ricker 1981). A recent study by Swain et al. (2007; hereafter referred to as SSH) makes a valuable attempt to demonstrate such an effect on length-at-ag...
متن کاملCommunity composition and diversity of zooplankton in the northwest Persian Gulf
Survey on zooplankton composition was studied during June 2015 to March 2016, by selecting six stations along the coastal waters of Bushehr (the Northwest Persian Gulf). Twenty four zooplankton taxa were identified, and the different zooplankton groups represented twenty-one families. Copepoda was recorded with the most abundance (53.30 %) followed by Malacostraca (32.87 %), which in turn was f...
