互惠移植实验证明了寄生贻贝幼虫与苦味鱼之间的动态共同进化关系

宿主与寄生虫之间的共同进化动态从严格的局部适应到扩散的行会共同进化各不相同。先天和后天免疫反应如何调节宿主对寄生虫的抵抗力，宿主的特异性和地理尺度如何影响宿主反应的效力，这些都会对范围动态和生物入侵产生影响。通过相互移植实验，我们测试了在欧洲和东亚的苦丁鱼与淡水贻贝幼体（球藻）之间的寄主-寄生虫关系中，局部或扩散的共同进化是否会影响寄主对寄生虫的反应。我们发现，钩毛蚴最初会不加区分地附着在所有研究宿主物种上，但在感染后24小时内，宿主的免疫反应会出现显著差异，这种差异在钩毛蚴发育过程中会加剧。欧洲苦木对欧洲钩毛虫的抗性较强，亚洲苦木对亚洲钩毛虫的抗性较强，其中亚洲苦木寄主的抗性地域偏差最大。这一发现表明当地适应性的影响很大，但也表明共同进化热点的作用不容忽视。因此，苦丁属物种上的低自然钩毛虫负载量总体上是由合格的免疫反应而非钩毛虫回避行为引起的。苦树的免疫反应主要是先天性的，而不是后天获得的。总之，我们的数据证明了寄生虫压力对宿主抗性进化的复杂影响，以及地理结构上的共同进化在形成宿主反应中的重要作用。

期刊介绍： Freshwater Biology publishes papers on all aspects of the ecology of inland waters, including rivers and lakes, ground waters, flood plains and other freshwater wetlands. We include studies of micro-organisms, algae, macrophytes, invertebrates, fish and other vertebrates, as well as those concerning whole systems and related physical and chemical aspects of the environment, provided that they have clear biological relevance. Studies may focus at any level in the ecological hierarchy from physiological ecology and animal behaviour, through population dynamics and evolutionary genetics, to community interactions, biogeography and ecosystem functioning. They may also be at any scale: from microhabitat to landscape, and continental to global. Preference is given to research, whether meta-analytical, experimental, theoretical or descriptive, highlighting causal (ecological) mechanisms from which clearly stated hypotheses are derived. Manuscripts with an experimental or conceptual flavour are particularly welcome, as are those or which integrate laboratory and field work, and studies from less well researched areas of the world. Priority is given to submissions that are likely to interest a wide range of readers. We encourage submission of papers well grounded in ecological theory that deal with issues related to the conservation and management of inland waters. Papers interpreting fundamental research in a way that makes clear its applied, strategic or socio-economic relevance are also welcome. Review articles (FRESHWATER BIOLOGY REVIEWS) and discussion papers (OPINION) are also invited: these enable authors to publish high-quality material outside the constraints of standard research papers.
