The breeding success of humpback whales in the Gulf of St Lawrence has fallen significantly, according to a new study led by the University of St Andrews.
Widespread, major changes have been documented in the world’s oceans over the last decades as a result of climate change. How these large-scale changes will affect populations of top marine predators, including whales for example, is largely unknown.
Researchers Dr Joanna Kershaw, Professor Patrick Miller and Professor Ailsa Hall of the Sea Mammal Research Unit (SMRU) at the University of St Andrews collaborated with colleagues at the Mingan Island Cetacean Study (MICS) and the Department of Fisheries and Oceans in Canada, to investigate if environmental shifts measured in the Gulf of St Lawrence, an important summer feeding ground for humpback whales, could be affecting their breeding.
