Survival plants in climate change learn to "walk"

Recently, the reporter learned from Xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences that in order to understand whether plants can keep up with the pace of climate change and survive under the climate change, Richard Corlett, a researcher of the garden, and David of the federal scientific and industrial research organization of Australia In collaboration with Professor Westcott, we found that most of the plants on the earth may not be able to keep pace with the speed of climate change, but the situation in Yunnan may be slightly better The study is published in ecology and evolutionary trends It is reported that every plant has an adaptation or tolerance range for climate change, which is called "climate adaptation range" Within this range, plants can survive, or they are likely to die As a result of climate change, the adaptive range of plants is constantly moving on the earth's surface In order to stay in the adaptive range, plants must also move with it By comparing the migration rates of various plants and their adaptation to climate change in the next century, the researchers found that, unlike animals, plants can only migrate once in each generation through seed dispersal The researchers assessed that most plants move less than one kilometer a year, while many others move less At the same time, the study also found that because of the significant climate gradient in Yunnan, the plants are likely to reach the adaptation area through a shorter migration distance, and even the plants with a slower migration can find the appropriate area and survive.
