Loss of microsatellite diversity and low effective population size in an overexploited population of New Zealand snapper (Pagrus auratus)
TLDR
If such low Ne/N ratios are commonplace in marine species, many exploited marine fish stocks may be in danger of losing genetic variability, potentially resulting in reduced adaptability, population persistence, and productivity.
Evolution of habitat use by deep-sea mussels
TLDR
Bayesian phylogenetic analysis and maximum-likelihood estimates of ancestral character states revealed that vent species evolved multiple times, and that reversals in vent and seep habitat use occurred within the sampled taxa.
Allozyme and microsatellite DNA markers of toothfish population structure in the Southern Ocean
TLDR
The microsatellite DNA heterogeneity suggests that there is restricted gene flow through the Southern Ocean, and that the different fishing grounds may support independent stocks.
Genetic divergence of kingfish from Japan, Australia and New Zealand inferred by microsatellite DNA and mitochondrial DNA control region markers
TLDR
Significant genetic divergence was observed between the kingfish population from Japan and those from Australia–New Zealand and there was no significant differentiation among the Australian and New Zealand population samples.
A comparison of three genetic methods used for stock discrimination of orange roughy, Hop/ostethus at/anticus: allozymes, mitochondrial DNA, and random amplified polymorphic DNA
TLDR
There was no significant differ­ ence between the two northern spawn­ ing populations for any marker, but there were significant differences be­ tween all other pairwise population com­ parisons with allozymes and RAPD's.
BLOOD FLOW AND PRESSURE CHANGES IN EXERCISING OCTOPUSES (OCTOPUS VULGARIS)
TLDR
Problems of the maintenance of a circulation in an animal with a high metabolic rate and the basic body plan of a mollusc are discussed, and the situation in squid is compared with that in octopuses.
Genetic variation in marine molluscs
TLDR
An excess of homozygotes was observed at many loci in most species of molluscs and such a phenomenon has not been observed in marine teleosts.
