Abstract Highly mobile species are considered to be the first to respond to climate change by transforming their ranges of distribution. There is evidence suggesting that Pipistrellus nathusii, a species capable of long-distance migration, is expanding both its reproduction and overwintering ranges to the North. We recorded the echolocation calls of bats at 16 sites in South-Western Finland on two consecutive winters, and detected calls of P. nathusii at one of the sites throughout the second winter. To our knowledge, this is the northernmost record of an overwintering P. nathusii, and contributes to evidence that the species is already responding to climate change.

Nathusius'pipistrelle (Pipistrellus nathusii) 在北纬 60°以上的纬度越冬的第一个记录

摘要 高度流动的物种被认为是第一个通过改变其分布范围来应对气候变化的物种。有证据表明，能够长距离迁徙的 Pipistrellus nathusii 正在向北方扩展其繁殖和越冬范围。我们连续两个冬天在芬兰西南部的 16 个地点记录了蝙蝠的回声定位呼叫，并在整个第二个冬天在其中一个地点检测到 P. nathusii 的呼叫。据我们所知，这是越冬 P. nathusii 的最北记录，并有助于证明该物种已经对气候变化做出反应。
