摘要
报道人为设置 6种不同生境对黑眶蟾蜍 (BufomelanostictusSchneider)幼蛙存活时间的影响研究。结果表明 :水深超过体长或干燥环境都对幼蛙不利 ,存活时间短。水深低于幼蛙体长并设有陆地或保持环境泥沙湿润为适宜的生境。在适宜生境条件下 ,幼蛙平均存活674 86h ,最长达 35d。
This paper deals with the effect on the life_span of Bufo melanostictus Schneider larva in the six different artificial environments.As a result, when the depth of water exceeds the length or the surroundings is dry, it is harmful to the larva, which will shorten the life. If the water is lower than its length or the surroundings silt keeps damp, it is suitable for the 4 larva to live. underthis advantageous condition, the larva can live 674.86 h, and its length will be 35 days at most.
