Activities of Rana kukunoris in Summer and Autumn Around the Seasonal Pond in Zoige Alpine Peat Land
四川省若尔盖季节性水塘周边高原林蛙夏秋季活动特征

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.
