扩散在塑造生物和生态过程中发挥着关键作用，例如空间结构种群的分布或入侵的速度和规模。在这里，我们已经研究了远距离传播行为的害虫控制的金钱蜘蛛，Erigone atra，和分布的母体内获得的内共生体在更广泛的元人口之间的关系。这种蜘蛛在异质环境中持续存在，因为它能够通过使用丝作为帆的主动长距离空中传播来扩展区域，这一过程称为“气球”。我们发现，在更广泛的大肠杆菌内，两种母体获得性内共生体感染的患病率存在空间异质性。atra元人口，我们通过几种独立的方法证明了这些内共生体之一，立克次体的存在和长距离运动的趋势之间的联系。这一新的发现，特别是内共生体可以影响主机的扩散是非常广泛的重要性，因为在节肢动物群落中的类似细菌的发生。限制扩散的细菌表型不仅有可能减少基因流动，从而有助于物种内的生殖隔离程度，而且还影响物种分布，从而影响整个群落的组成。
Dispersal plays a key role in shaping biological and ecological processes such as the distribution of spatially-structured populations or the pace and scale of invasion. Here we have studied the relationship between long-distance dispersal behaviour of a pest-controlling money spider, Erigone atra, and the distribution of maternally acquired endosymbionts within the wider meta-population. This spider persists in heterogeneous environments because of its ability to recolonise areas through active long-distance airborne dispersal using silk as a sail, in a process termed 'ballooning'. We show that there is spatial heterogeneity in the prevalence of two maternally acquired endosymbiont infections within the wider E. atra meta-population and we demonstrate through several independent approaches a link between the presence of one of these endosymbionts, Rickettsia, and the tendency for long-distance movement. This novel finding that particular endosymbionts can influence host dispersal is of broad importance given the extremely widespread occurrence of similar bacteria within arthropod communities. A bacterial phenotype that limits dispersal has the potential not only to reduce gene flow and thus contribute to degrees of reproductive isolation within species, but also to influence species distribution and thus overall community composition.
