Not all species suffering from global warming, will be maintained, while moving to new habitats. To such conclusion experts from the UK, representing the University of Exeter.
There is a theory that for many living beings to global warming is less dangerous than it might seem at first glance. If their usual territory is becoming too hot to the North (or South in southern hemisphere) temperature from becoming excessively cold comfort for these animals. Thus truly “nowhere to run” is a polar inhabitants such as polar bears. In the past, the specialists from Harvard University have suggested that the canadian and Siberian taiga seven decades will be the new home for birds, deer and bobcats, to date dwelling to the South.
However, at the time when the study was published, one could conclude that such migration will protect from global warming is not all — shortly before it from the face of the earth vanished reef mosaic rats, and the main reason experts call it climate change. By the way, it was the first in modern history where the victims of global warming became a mammal, and many experts expressed concern that it may not be the last.
Researchers from Exeter University asked a question, what are the chances of each individual species to survive in a changing climate, and what those chances are depend. It is not surprising that the greatest security was the species able to feel comfortable in a large temperature range and are not picky in food. However, many animals, especially “complex” from a biological point of view, can survive and reproduce only in strictly certain conditions, although their “migration” could become the salvation, they can simply not manage to move to new places before a familiar habitat will become unsuitable for them.
Of course, an important factor was the ability to travel long distance to have time to find a new place to live, but in some cases will not provide salvation because the potential new house will be far and the path is not obvious.
Finally, animals need to “gain a foothold” in a new place, and it will be, mostly, types, beginners to reproduce at an early age and leaves a large number of offspring.
Experts have studied the 62 different species that are increasingly threatened by climate change, and concluded that 30 of these species is unlikely anything to oppose this.
The study was published in the journal Diversity and Distributions.
