Genetic variation among populations of the Antarctic toothfish: evolutionary insights and implications for conservation
Mantel test. From a conservation perspective, low levels of genetic diversity may be indicative of ... relatively small populations that would not be able to withstand heavy commercial fishing pressures. Given ... that there is evidence for significant genetic structure, it will be important to manage these ...
