Abstract

Predators affect prey directly by predation and indirectly by triggering behavioral responses that aim at reducing predation risk. In this paper, I present a method for training an avian predator which can allow separating between its direct and indirect effects on prey in various experimental setups. Barn owls are found to be a valuable tool for empirically testing different hypotheses related to predator-prey interactions, population dynamics, and inter-specific competition, all performed in the field using authentic rodent prey and their natural predators. Barn owls are raised and trained to participate in field experiments using classical conditioning, and are trained either to catch rodents or only to fly above a certain area without making any attempt to attack the prey, simulating solely predation risk. Body mass is a crucial factor in the training procedure, and I thus define five body mass ranges that characterize different behavioral stages in the training of owls. A logistic model is used to ca...

训练仓鸮:生态实验的有力工具
捕食者通过捕食直接影响猎物,并通过触发旨在降低捕食风险的行为反应间接影响猎物。在本文中,我提出了一种训练鸟类捕食者的方法,该方法可以在各种实验设置中分离其对猎物的直接和间接影响。谷仓猫头鹰被发现是一个有价值的工具,用于经验检验与捕食者-猎物相互作用,种群动态和种间竞争有关的不同假设,所有这些都是在实地使用真实的啮齿动物猎物和它们的天然捕食者进行的。仓鸮的饲养和训练是为了参加经典条件反射法的野外实验,它们要么被训练捕捉啮齿动物,要么只在特定区域上空飞行,不试图攻击猎物,只模拟被捕食的风险。体重是训练过程中的一个关键因素,因此我定义了五个体重范围,以表征猫头鹰训练中不同的行为阶段。使用逻辑模型来计算……
