宿主物种的行为生态学可能会影响其微生物群落，因为宿主的性别、饮食、生理和运动行为都可能影响其微生物群。我们研究了仓鸮（Tyto alba）的野生种群，并收集了有关其微生物群，运动，饮食，大小，颜色和繁殖的数据。不同性别的宿主和雌性猫头鹰的细菌种类的组成不同，有更多的细菌群落比他们的男性同行。放线菌科和乳杆菌科这两个细菌家族的丰度也因性别而异，这可能是由于激素和免疫功能的性别差异，正如先前在小鼠微生物群中发现的乳杆菌科。雄性和雌性猫头鹰在它们带到巢穴的猎物方面没有差异，这表明饮食差异不太可能是它们微生物群差异的基础。猫头鹰的运动行为与雄性和雌性的宿主微生物群有关，因为每天远离巢穴的猫头鹰比离巢穴更近的猫头鹰拥有更多样化的细菌群落。这一新的结果表明，宿主的运动生态学可能会影响它们的微生物群，这可能是基于它们在宿主移动和在景观中觅食时与新细菌物种的不同遭遇。总的来说，我们发现微生物群落的许多方面与宿主的行为生态学相关，并且微生物群的数据可以帮助产生关于宿主行为的新假设。
The behavioural ecology of host species is likely to affect their microbial communities, because host sex, diet, physiology, and movement behaviour could all potentially influence their microbiota. We studied a wild population of barn owls (Tyto alba) and collected data on their microbiota, movement, diet, size, coloration, and reproduction. The composition of bacterial species differed by the sex of the host and female owls had more diverse bacterial communities than their male counterparts. The abundance of two families of bacteria, Actinomycetaceae and Lactobacillaceae, also varied between the sexes, potentially as a result of sex differences in hormones and immunological function, as has previously been found with Lactobacillaceae in the microbiota of mice. Male and female owls did not differ in the prey they brought to the nest, which suggests that dietary differences are unlikely to underlie the differences in their microbiota. The movement behaviour of the owls was associated with the host microbiota in both males and females because owls that moved further from their nest each day had more diverse bacterial communities than owls that stayed closer to their nests. This novel result suggests that the movement ecology of hosts can impact their microbiota, potentially on the basis of their differential encounters with new bacterial species as the hosts move and forage across the landscape. Overall, we found that many aspects of the microbial community are correlated with the behavioural ecology of the host and that data on the microbiota can aid in generating new hypotheses about host behaviour.
