蝙蝠是许多人畜共患病病毒的储备宿主。但是关于个体蝙蝠内病毒的多样性和丰度的了解还较少,因此它们之间病毒共感染和溢出的频率也不清楚。我们用无偏的元转录组学方法,对中国云南省采样的149只个体蝙蝠中携带的哺乳动物相关病毒进行了表征。结果显示研究的动物中病毒的高频共感染(即蝙蝠个体同时感染多种病毒物种)和溢出,这可能进一步促进病毒的重组和再组合。

在全球变化背景下,管控入侵物种是一项具有挑战性的工作。这主要由于从入侵物种的入侵性推断它们的生态危害存在很大的不确定性。更确切地说,入侵性和生态危害的关系可能依赖于所研究的生态系统,同时这种关系还没有在像青藏高原这样独特的高寒生态系统中被研究过。在这项研究中,我们在青藏高原东南部的一个样带上调查了32种入侵植物。我们将这些入侵物种的生态危害分解为分布范围(R)、局部丰度(A)和个体对本地植物群落的影响(E)3个组分,并研究了植物性状对这些组分的相对贡献。研究结果表明,入侵植物的入侵性(R×A)和其所产生的危害(R×A×E)没有相关性。这表明这些入侵植物的入侵性不能反映它们对本地群落生态危害的严重性。在青藏高原,R和A共同驱动了入侵性,而R单独驱动了生态危害。植物性状并没有通过这3个组分驱动入侵性和生态危害,只有果实类型(主要是浆果)影响了E。我们的结果表明,驱动入侵性和生态危害的组分的不匹配导致了入侵植物的入侵性不能反映它们的生态危害。因此,关于入侵物种的管控应该优先考虑那些分布广泛的物种或者已经被证实会对本地物种产生负面影响的物种。

plant-insect interactions are key model systems to assess how some species affect the distribution, the abundance, and the evolution of others. Tree reproductive structures represent a critical resource for many insect species, which can be likely drivers of demography, spatial distribution, and trait diversification of plants. In this review, we present the ecological implications of predispersal herbivory on tree reproductive structures by insects (PIHR) in forest ecosystems. Both insect's and tree's perspectives are addressed with an emphasis on how spatiotemporal variation and unpredictability in seed availability can shape such particular plant-animal interactions. reproductive structure insects show strong trophic specialization and guild diversification. Insects evolved host selection and spatiotemporal dispersal strategies in response to variable and unpredictable abundance of reproductive structures in both space and time. If PIHR patterns have been well documented in numerous systems, evidences of the subsequent demographic and evolutionary impacts on tree populations are still constrained by time-scale challenges of experimenting on such long-lived organisms, and modeling approaches of tree dynamics rarely consider PIHR when including biotic interactions in their processes. We suggest that spatially explicit and mechanistic approaches of the interactions between individual tree fecundity and in sect dynamics will clarify predictions of the demogenetic implications of PIHR in tree populations. In a global change context, further experimental and theoretical contributions to the likelihood of life-cycle disruptions between plants and their specialized herbivores, and to how these changes may gen erate novel dynamic patterns in each partner of the interaction are increasingly critical.
