One of the major predators of the South Seas is at risk of extinction. The gray-headed albatrosses, seabirds of the Southern Ocean can not find alternatives to changes in the food chain caused by warming waters. The lack of food may order this species to extinction, warns a study of how the Sea Institute, University of Coimbra, held in conjunction with the British Centre for Antarctic Research.
“We found a top predator changes to your diet and try to find solutions to the problem, but without success,” explained José Xavier, a researcher who led the research in Antarctica in the last 15 years in Antarctica. Quoted by Lusa, marine biologist stressed that the birds “can not find enough food to feed the puppies and hence make its population remains.”
risk has worsened since, in 2000, the Southern Ocean reached the hottest temperature ever. “When the ocean is too warm, the effect of temperature will affect the amount of algae, fish and whole food chain, from the bottom to the top predators,” explained José Xavier, noting that “the Southern Ocean is not is homogeneous “and the effects on the food chain vary” depending on the different regions. “
“Albatrosses are an example of a top predator, such as whales, seals and penguins, which can lead us to understand how these animals can be adapted to the climatic conditions and the Southern Ocean that is malfunctioning “explained the researcher.
