The adaptive evolution of contrasting leaf phenology among Daphne species and its implications on species' current invasive-extinction risks

瑞香叶物候的多样性(从夏季落叶到冬季落叶再到常绿)使每个物种都能在各自的栖息地生存，但不同的叶物候的进化可以追溯到它们系统发育中存在的生态生理限制。由此产生的物候表现似乎是一些常绿物种(月桂花)入侵成功和其他冬季落叶物种(朝鲜月桂花)易受伤害的部分原因。

The diverse leaf phenology in Daphne (from summer deciduous to winter deciduous to evergreen) allows each species to survive in their respective habitats but the evolution of the contrasting leaf phonologies can be traced to ecophysiological constraints present in their phylogeny. The resulting phenological expression appears to be partly responsible for the invasive success of some evergreen species (D. laureola) and the vulnerability of other winter deciduous species (D. pseudomezereum var.koreana)
