Cod Wars a collision with the British frigate "Apollo", they collided again, on 29 August 1973. Several explanations for the Cod Wars have been put forward. Recent studies have focused on the underlying economic, legal and strategic drivers for Iceland and the United Kingdom, as well as the domestic and international factors that contributed to the escalation of the dispute. Lessons drawn from the Cod Wars have been applied to international relations theory. Fishermen from Britain began to fish in the international waters near Iceland in the 15th century. From the early 16th century onward, English sailors and fishermen were a major
Blue cod change. Since a number of evidence indicated that blue cod are relatively sedentary, the fishing pressure may lead to potential local depletion. Recent studies showed that the genetic differences were significant between mainland List of islands of New Zealand population and Chatham Island population. On the other hand, the differences within mainlandList of islands of New Zealand populations were limited while the pattern of the isolation by distance was detected. Further research using microsatellite DNA markers suggested that some significant genetic differences between mainland population exist which indicate the potential long-distance dispersal, but the dispersal rate is too low to
