15.One butterfly species has come back from near extinction (灭绝)and is beginning to quickly adapt to warmer weather,a new research has found.
The research,presented at the Butterfly Conservation's international conference,found that the quino checkerspot butterfly has both moved to higher,cooler altitudes and has chosen an entirely new plant on which to lay its eggs.The butterfly,once thickly settled in Mexico and California,has witnessed a sharp drop in its numbers as climate change sees temperatures in their natural habitats(栖息地)become too hot and dry for the food plant its babies eat.
Camille Parmesan,professor at Plymouth University said that while the butterfly's movement is encouraging,it also points to the need for habitat protection.If the butterflies-and potentially other species-adapt quickly enough to move to higher altitudes,it's required that healthy environments exist in those altitudes in which the butterflies can settle.It's also required that these species have corridors(走廊)by which to move to higher altitudes,so that they can avoid getting killed by roads or long stretches of developed land.
Scientists believe the quino checkerspot is the first butterfly species to change habitat and diet so quickly,but it's not the only species to be forced to adapt to climate change.A 2013 study found that,while trees aren't moving northward as quickly as scientists expected,they're instead speeding up their lifecycles,causing younger trees to replace older trees at a higher rate.Certain desert plants,on the other hand,have migrated(迁徙)surprisingly far upslope,with some moving more than 800 feet from their 1963 lowermost boundaries.
Other species aren't adapting so quickly,however.The migration patterns of many butterfly species are being changed by earlier and warmer springs-something that's happening to some bird species as well.This changed migration timing could lead to mismatches in food and weather conditions for the migrating species,with food sources that were traditionally obtainable at a migration destination hatching or blooming(开花) too early for the birds or butterflies to consume.
