Between entanglements in fishing gear, ship strikes and climate change, the past few decades have been rough for the North Atlantic right whale. Scientists at St Andrews University in the UK recently studied the cumulative effects of these stressors on the health and survival of this endangered whale. They concluded that its survival was mainly influenced by entanglements and collisions, as well as variations in the abundance of prey in its environment.<\/p>\n
To reach these conclusions, the researchers analyzed data collected from 729 North Atlantic right whales between 1970 and 2020. Using a model that evaluates the cumulative effects of various stressors (anthropogenic and non-anthropogenic), the research team was able to establish that the fitness level of right whales was trending upward until 1990, before declining and stabilizing around the 2000s. For the past decade, however, the health of right whales has entered a steady decline.<\/p>\n","protected":false},"excerpt":{"rendered":"
