Abstract

ABSTRACT Compared to chewing lice, symbiotic and studies on their biology, ecology and survival strategies are still rare. To describe the ecology and morphology of the mite species Proctophyllodes megaphyllus, a symbiont of the alpine accentor Prunella collaris, 150 accentors were captured in the West Carpathian Mountains of Slovakia. The mites extracted from the birds were sexed and their specific body structures were measured. In total 2144 individuals of P. megaphyllus were collected from 100 accentors. Male mites collected in autumn, after the bird's postnuptial moult, reached the largest size. At the same time, mite prevalence reached maximum while the mean intensity of infestation was at its lowest. Our results suggest that mites preferred newly coated feathers after a moult and radiated horizontally, infesting birds at shared roosting sites where alpine accentors tend to reoccur. This study is one of the few evaluations of seasonal variation in ecology and morphology of feather mites in alpine conditions.

巨斑原叶螨在寄主寒藓上的生存策略及季节大小变化
摘要与咀嚼虱子相比,共生及其生物学、生态学和生存策略的研究仍然很少。为了描述大叶原叶螨的生态和形态,在斯洛伐克的西喀尔巴阡山脉捕获了150只大叶原毛螨。对从这些鸟身上提取的螨虫进行了性别鉴定,并测量了它们的特定身体结构。共从100个寄主植物中采集到2144个大叶藻个体。在秋季采集的雄螨,在鸟婚后蜕皮后,达到了最大的体型。同时,螨的发病率最高,而平均感染强度最低。我们的研究结果表明,螨虫在蜕皮后更喜欢新覆盖的羽毛,并水平辐射,在高山口音容易复发的共同栖息地侵扰鸟类。这项研究是为数不多的对高山条件下羽螨生态和形态季节变化的评估之一。
