铁路运输正在扩大,预计到2050年,全球基础设施将增加三分之一。预计更多地依赖铁路将通过减少与运输有关的碳排放,在全球范围内造福环境。然而,对野生动物更小规模、更直接的影响尚不清楚,因为与公路不同,铁路对动物生态的影响很少被研究。作为一个群体,蝙蝠经常与交通网络互动,因为它们的广泛分布和大规模的运动。此外,它们的非对称性和回声定位的使用意味着蝙蝠可能会受到火车发出的光线和噪音的影响。为了调查经过的火车是否会影响蝙蝠的活动水平,我们在英格兰南部的12个树木繁茂的铁路边站点使用超声波探测器监测了英国最丰富的两种蝙蝠。每次火车经过时,活动都会下降≥ 30-50%,至少持续两分钟。因此,在中等铁路交通量的地点,活动减少了不少于五分之一的时间,在最繁忙的地点,活动减少了三分之二或更多的时间。这种活动的变化意味着一再采取逃避行动和/或被排除在其他有利环境之外,并可能造成相应的机会或精力成本。因此,经过的火车的干扰可能会使大多数铁路旁栖息地的蝙蝠处于不利地位。
Rail transport is expanding, with a global increase in infrastructure of up to one-third predicted by 2050. Greater reliance on rail is expected to benefit the environment at a planetary level, by mitigating transport-related carbon emissions. However, smaller-scale, more direct consequences for wildlife are unclear, as unlike roads, railway impacts on animal ecology are rarely studied. As a group, bats frequently interact with transport networks due to their broad distribution and landscape-scale movements. Additionally, their nocturnality, and use of echolocation mean bats are likely to be affected by light and noise emitted by trains. To investigate whether passing trains affect bat activity levels, we monitored the two most abundant UK species using ultrasonic detectors at 12 wooded rail-side sites in southern England. Activity fell by ≥ 30–50% each time a train passed, for at least two minutes. Consequently, activity was reduced for no less than one-fifth of the time at sites with median rail traffic, and two-thirds or more of the time at the busiest site. Such activity changes imply repeated evasive action and/or exclusion from otherwise favourable environments, with potential for corresponding opportunity or energetic costs. Hence, disturbance by passing trains may disadvantage bats in most rail-side habitats.
