This study is based on the behavioral responses of Leptodactylus albilabris tadpoles, a widely abundant frog native to Puerto Rico. We evaluated changes in habitat preference and activity levels in the presence of a predator (fish). Tadpoles were collected and allocated to one of three treatments: no fish predator, one fish (Astronotus ocellatus), and two fish. Results showed a significant decrease in activity levels of tadpoles and change in microhabitat use in the presence of a predator. However, there was no significant difference in tadpole activity when the second predator was added. The preferred habitat in the presence of a predator was leaf litter, even though L. albilabris tadpoles are benthic and usually favor hiding in the sediment. The larval stage of the anuran life cycle is the most vulnerable, and these changes in behavior increase the probability of escaping predators to reach metamorphosis and finally reproduce.

捕食者在场的安迪尔白色唇蛙（Leptodactylus albilabris）Ta的行为变化：生境使用偏好和活动水平

这项研究基于Leptodactylus albilabris ad的行为反应，Leptodactylus albilabris ad是波多黎各当地人的一种广泛丰富的青蛙。我们评估了存在捕食者（鱼）时栖息地偏好和活动水平的变化。收集并将其分配给以下三种处理方法之一：不捕食鱼类，不​​捕食一条鱼（Astronotus ocellatus），不捕食两条鱼。结果表明，在存在捕食者的情况下，activity的活动水平显着下降，微生境的使用也发生了变化。但是，添加第二种捕食者时，activity的活动没有显着差异。在天敌存在的情况下，首选的栖息地是落叶，即使L. albilabris t是底栖动物，通常也喜欢藏在沉积物中。阿努兰生命周期的幼虫阶段最脆弱，
