我国科学家 成功繁育濒危物种横斑玉斑蛇后代
2017-08-25 04:46:51 中国青年网
这是8月24日在中国科学院成都分院一个实验室内拍摄的横斑玉斑蛇。
记者24日从中国科学院成都分院了解到,历经3年,我国科学家人工饲养并繁育出濒危物种横斑玉斑蛇后代,结束了我国珍稀蛇类均由国外率先人工繁育成功的历史。
2014年,“芦山地震后小种群动物调查与恢复保护项目”启动后,中科院成都生物研究所副研究员丁利在天全县喇叭河自然保护区寻觅了一个多月,抓到了一公一母两条横斑玉斑蛇。虽然千辛万苦抓到了这两条活体蛇,但它们连续3年却不生育。研究人员决定调控实验室温度,并给予适当光照,以诱导其发情繁育,终于获得成功。
