与气候变化有关的热状态改变正在对地球自然生态系统的物理、化学和生物特性产生重大影响，对水生生物的生物学产生重要影响。除了影响个别物种的生物学，不断变化的温度状况有能力调节物种之间的生态相互作用，气候变化影响水生生态系统中宿主-寄生虫相互作用的潜力现在已得到充分认识。预测寄生虫在其生命周期中与多个宿主感染的流行率和强度会发生什么特别具有挑战性，因为每增加一个额外的宿主都会大大增加潜在的反应排列。在这篇简短的评论中，我们提供了一个概述的不同途径，改变热制度可以影响水生生态系统中的多宿主寄生虫生命周期的动态。此外，我们将研究如何实验适用的主机-寄生虫系统被用来确定这些不同类型的机制的环境温度变化的后果。我们的首要目标是研究改变热机制的潜力，不仅改变宿主和寄生虫的生物学，而且改变宿主和寄生虫之间相互作用的生物学。我们还希望说明的复杂性，这是可能参与预测的动态感染的多宿主寄生虫在热挑战的水生生态系统。
Altered thermal regimes associated with climate change are impacting significantly on the physical, chemical, and biological characteristics of the Earth's natural ecosystems, with important implications for the biology of aquatic organisms. As well as impacting the biology of individual species, changing thermal regimes have the capacity to mediate ecological interactions between species, and the potential for climate change to impact host-parasite interactions in aquatic ecosystems is now well recognized. Predicting what will happen to the prevalence and intensity of infection of parasites with multiple hosts in their life cycles is especially challenging because the addition of each additional host dramatically increases the potential permutations of response. In this short review, we provide an overview of the diverse routes by which altered thermal regimes can impact the dynamics of multi-host parasite life cycles in aquatic ecosystems. In addition, we examine how experimentally amenable host-parasite systems are being used to determine the consequences of changing environmental temperatures for these different types of mechanism. Our overarching aim is to examine the potential of changing thermal regimes to alter not only the biology of hosts and parasites, but also the biology of interactions between hosts and parasites. We also hope to illustrate the complexity that is likely to be involved in making predictions about the dynamics of infection by multi-host parasites in thermally challenged aquatic ecosystems.
