四川省若尔盖季节性水塘周边高原林蛙夏秋季活动特征

Activities ofRana kukunori in Summer and Autumn Around the Seasonal Pond in Zoige Alpine Peat Land

  • 摘要: 摘要:影响无尾两栖类空间活动特征的因素很多,水体是主要因素。本研究采用样线法, 于2006年7月4-26日和9月21-27日两个时期对若尔盖季节性水塘周边高原林蛙的空间活动特征进行了研究,结果表明:夏季高原林蛙主要围绕水塘活动,高原林蛙发现率与水塘距离呈显著负相关,90%的高原林蛙个体在距离水塘110m的范围内活动。秋季高原林蛙的活动与水塘距离没有显著相关性,且表现出散布和迁移的趋势,一次长距离 (>50m) 移动后,会在新的生境中停留2-3天,然后继续移动 (待发表)。通过与戴强等 (2005) 秋季的研究比较得出:不同的生境中,高原林蛙的空间活动特征不同。关键字:若尔盖,高原林蛙,季节性水塘,空间活动

     

    Abstract: Abstract: The water environment has important features that affect the activities of anurans. The activities of Rana kukunoris around the seasonal pond was investigated using transects, in late July and September, respectively. The transects were set in eight directions: north, south, west, east, northwest, northeast, southwest and southeast. The transects were two meters in width and 70-150 m in length. It was indicated that R. kukunoris moved around the pond in summer and there was significant negative correlation between the percentage of frog numbers and distance to the aquatic site (Pearson, adult:r = -0.479, P < 0.05; sub-adult: r = -0.480, P < 0.05). Ninety percent of the frogs recorded were distributed in an area around the pond in a radius of 110 m. In contrast to sub-adults, the adult frogs tended to dissipate away from the pond and preferred to choose the mouth of the spring as a habitat. However, there was no significant correlation between the percentage of frog numbers and the distance from the seasonal pond in autumn (Pearson, r = -0.016, P > 0.05), the percentage of frog numbers was very low and frogs preferred the mouth of the spring as a habitat.
