Conservationists are predicting wildlife will be affected by climate change in the Channel Islands over the next 50 years.
A report by conservation group WWF has asked governments to do more to protect marine life from global warming.
But WWF said the geographical position of the islands made them particularly vulnerable to changes.
WWF Research Officer Emily Lewis-Browns said such changes would affect animals' breeding rates.
Ms Lewis-Browns, a marine research officer for WWF, said: "Certainly any storms may affect the Channel Islands more so than other areas, and also the warming of temperatures will be more noticeable because it's an area that is always going to be warmer than the north of Scotland, for example."
Ms Lewis-Browns added that varying sea temperatures which could be brought about by global warming would affect animals' reproduction.
She said: "What we find in warm seas is that the warming effect reduces productivity.
"Seas that are cooler have increased productivity. So, as seas warm, it reduces productivity."
