Tropicalisation is a marine phenomenon arising from contemporary climate change, and is characterised by the range expansion of tropical/subtropical species and the retraction of temperate species. Tropicalisation occurs globally and can be detected in both tropical/temperate transition zones and temperate regions. The ecological consequences of tropicalisation range from single-species impacts (e.g., altered behaviour) to whole ecosystem changes (e.g., phase shifts in intertidal and subtidal habitats). Our understanding of the evolutionary consequences of tropicalisation is limited, but emerging evidence suggests that tropicalisation could induce phenotypic change as well as shifts in the genotypic composition of both expanding and retracting species. Given the rapid rate of contemporary climate change, research on tropicalisation focusing on shifts in ecosystem functioning, biodiversity change, and socioeconomic impacts is urgently needed.

热带化是当代气候变化引起的一种海洋现象，其特点是热带/亚热带物种的范围扩大和温带物种的缩小。热带化发生在全球范围内，并且在热带/温带过渡区和温带地区都可以检测到。热带化的生态后果范围从单一物种影响（例如行为改变）到整个生态系统变化（例如潮间带和潮下生境的相变）。我们对热带化的进化后果的理解是有限的，但新出现的证据表明，热带化可能会引起表型变化以及扩张和收缩物种的基因型组成的变化。鉴于当代气候变化的速度之快，迫切需要对热带化进行研究，重点关注生态系统功能的变化、生物多样性的变化和社会经济影响。
