“Researchers have conducted a genetic analysis of more than 6,000 Atlantic cod from different regions of the ocean, using DNA markers. They found that the cod clustered into five distinct groups, based on their geographic origin and migration patterns. These groups showed little or no evidence of interbreeding, suggesting they are reproductively isolated and may represent different species. This finding has implications for the conservation and management of Atlantic cod, as each group may have different ecological and evolutionary traits.“
“Researchers have found that superb fairy-wrens can learn to associate unfamiliar sounds with danger through social learning. The birds were played a computer-generated “buzz” as part of a chorus of alarm calls from other bird species. By the end of the training period, 80% of the birds flew away and hid if they heard the computer buzz on its own. The study is the first to show the specific mechanism of social learning through acoustic-acoustic association.“
