Traffic noise is known to negatively affect many wildlife species by interfering with foraging behavior. Frogs often lay their eggs in roadside ditches because they are predator-free, but it is possible that traffic noise could reduce the survival and fitness of tadpoles, creating an ecological trap. In a series of lab experiments, we tested whether traffic noise has a negative impact on tadpole feeding behavior, whether this is mediated by changes in tadpole activity, and whether there is any impact on tadpole growth rate or metamorphosis. Traffic noise exposure significantly reduced the amount of food consumed by Cuban Treefrog (Osteopilus septentrionalis) tadpoles. Traffic noise exposure also increased the activity level of both Southern Toad (Anaxyrus terrestris) and Cuban Treefrog tadpoles, which could possibly make them more noticeable to predators in the wild. However, these behavioral changes were not associated with changes in growth rate or timing of metamorphosis. We caution, however, that this study aimed to isolate the specific impact of traffic noise, and did not investigate other road effects that may be damaging to tadpoles.

交通噪声对t行为和发育的影响

众所周知，交通噪声会通过干扰觅食行为而对许多野生动植物造成负面影响。青蛙通常会在路边的沟渠中产卵，因为它们没有捕食者，但是交通噪音可能会降低reduce的生存和适应性，从而形成生态陷阱。在一系列的实验室实验中，我们测试了交通噪音是否对feeding的摄食行为产生了负面影响，是否由by活动的变化介导，以及对on的生长速度或变态没有任何影响。交通噪音的暴露显着减少了古巴树蛙（Oseopilus septentrionalis）consumed消耗的食物量。交通噪音的暴露也增加了南蟾蜍（Anaxyrus terrestris）的活动水平。）和古巴树蛙t，这可能会使它们在野外的捕食者中更引人注意。但是，这些行为变化与生长速度或变态时间的变化无关。但是，我们提醒您，这项研究旨在隔离交通噪音的特定影响，并且未调查可能对t造成损害的其他道路影响。
