论文摘要
鱼类捕食会影响两栖动物的种群。大多数例子报告了侵入性鱼类及其对特定两栖动物的负面影响。在这里，我们提供了热带鱼类Tractosteus Tropicus在甘蔗toad bufo Marinus上发生的天然鱼类捕食。我们观察到了由曲皮杆菌攻击Marinus造成的身体损害。当成年B. Marinus被从人口亚to中移除时，将成年人的利基市场补充，以补充人口。鱼类对两栖动物捕食的局部观察对于区分自然人口的波动与两栖动物人口的下降很重要。
Fish predation can affect amphibian populations. Most examples report invasive fish species and their negative effect on specific amphibians. Here we provide an occurrence of natural fish predation by the tropical gar Atractosteus tropicus on the cane toad Bufo marinus. We observed physical damage caused by A. tropicus attacking B. marinus. When adult B. marinus were removed from the population subadult toads refilled the adults niche, resupplementing the population. Local observations of predation by fish on amphibians are important to differentiate natural population fluctuations from amphibian population declines.
