摘要

非洲水牛（Syncerus caffer）和啄木鸟（Buphagus spp.）之间的共生相互作用受到宿主特征和体外寄生虫负荷的影响。这项研究调查了个体特征，如体型、年龄和蜱负荷，如何影响啄木鸟的觅食决定。为了研究牛椋鸟是否选择在水牛身上觅食的影响，我们使用了候选广义线性模型。我们的研究结果表明，牛椋鸟优先选择体积较大、蜱虫负荷高于预期的水牛，特别是在肛周区域。这些发现强调了宿主大小和寄生虫丰度在大草原生态系统中塑造啄木鸟觅食行为的作用。

Impact of Individual Host Characteristics on Host Selection in Oxpeckers

Symbiotic interactions between oxpeckers (Buphagus spp.) and African buffalo (Syncerus caffer) are influenced by both host characteristics and ectoparasite load. This study investigates how individual traits, such as body size, age and tick load, impact oxpecker foraging decisions. To investigate what impacts whether or not oxpeckers choose to forage on a buffalo, we used candidate generalised linear models. Our results show that oxpeckers preferentially select larger buffalo with higher-than-expected tick loads, particularly in the perianal region. These findings highlight the role of host size and parasite abundance in shaping oxpecker foraging behaviour within the savannah ecosystem.

期刊介绍： African Journal of Ecology (formerly East African Wildlife Journal) publishes original scientific research into the ecology and conservation of the animals and plants of Africa. It has a wide circulation both within and outside Africa and is the foremost research journal on the ecology of the continent. In addition to original articles, the Journal publishes comprehensive reviews on topical subjects and brief communications of preliminary results.
