The response to climate warming in animal populations has penetrated to the level of the gene. It affects development, reproduction and dormancy, and this response is occurring in diverse groups of animals from insects to birds and mammals. A chromosomal map has been developed that will allow researchers to narrow their focus to identify specific genes that control the seasonal development of animals. The map shows regions of chromosomes that activate and are apparently evolving in animals in response to climate change.Such information will help predict which animals may survive in changing climate and identify which disease carrying vectors may move northward, allowing for the production of appropriate vaccines. The newly created map contains 900 million DNA base pairs.
