Study predicts dolphin extinctions from climate change
Some species of dolphins and other marine cetaceans could face extinction as climate change causes changes in local water temperatures.
A study by Dr Colin MacLeod of Aberdeen University predicts that water temperatures will be effected in 88% of waters in which dolphins and other cetaceans are found with the number of suitable habitats shrinking meaning fewer animals.
Dr MacLeod, said: “In the past, the main concern was for the small number of polar species likely to be affected by a decline in sea ice. However, this new study shows that there are many more species to be worried about.
“Some species found in temperate waters may be at risk not just because of the water temperatures they live in, but also because they only live in shallow waters. These species cannot simply respond to increases in sea temperature by moving into cooler neighbouring areas if the waters there are too deep.”
Dr MacLeod is now planning research aimed at identifying how different species are likely to react to changing water temperatures to provide data for dolphin conservation plans.
