Turtle Population Survey of the J. H. Barrow Field Station Nature Observatory Pond

We initiated a population survey of the pond turtle population in the Nature Observatory Pond at the J. H. Barrow Field Station, Hiram Township, Portage County, Ohio. We used PIT tags (AVID) to permanently mark turtles. We trap turtles using a combination of hoop-net traps (baited with sardines in oil) and basking traps. All turtles were measured (carapace and plastron length) and many were weighed. The vast majority of turtles were midland painted turtles, with several snapping turtles trapped. This is a long-term study.

我们于美国俄亥俄州波蒂奇县海勒姆镇J·H·巴罗野外站的自然观测池塘内开展了池塘龟类种群调查。本次研究使用被动集成应答器标签（PIT tags，AVID）对龟类实施永久性标记。采用围网陷阱（以油浸沙丁鱼为诱饵）与晒背陷阱相结合的方式捕获龟类个体。对所有捕获个体均测量其背甲与腹甲长度，并对多数个体完成体重称量。本次调查捕获的龟类绝大多数为中部锦龟（midland painted turtles），仅捕获到少量鳄龟（snapping turtles）。本项研究属于长期观测研究。
