Abstract Plant's life history can evolve in response to variation climate spatio‐temporally, but numerous multiple‐species studies overlook species‐specific (especially a foundation species) ecological effects and genetic underpinnings. For species successfully invade region, likely become species, life‐history of invasive plants exerts considerable evolutionary impacts on invaded ecosystems. We examined how an plant, Spartina alterniflora , varied its along latitudinal gradient using common gardens experiment. Two were located at range boundary tropical zone main distribution area S. temperate China. Within each population/garden, we measured the onset time three successive phenological stages constituting reproductive phase fitness trait. In low‐latitude garden with higher temperature, found that was advanced length prolonged compared high‐latitude garden. This could possibly due lower plasticity maturity time. Additionally, positively related Marginal population from tropic had lowest fitness, poor capacity cope changing environment may result reduction this population. These results reflected divergence Our study provided novel view test center–periphery hypothesis by integration across plant's highlighted significance considering evolution. Such insights help us understand long‐term consequences variation, implications for plant interaction, ecosystem functions under change.

Invasive alien species can cause significant economic and social-environmental damage after their invasive success. The red-eared slider (Trachemys scripta elegans) is among the first worst introduced to China has been recorded in numerous regions worldwide, not limited China. In this study, we used distribution models predict potential suitable habitat areas for T. s. elegans compare realized niche between its invaded native ranges. Additionally, forecasted changes under different future scenarios. We found that range of projected continue expanding future, imposing greater pressure on biological control efforts. constructed hypervolume eight environmental variables ranges elegans. Our study demonstrates that: 1) shifted following invasion, albeit retaining some aspects niche; 2) South, Central, East become a region rich habitats elegans; 3) influence human activities may be main reason deviation occurrence records from shifting allows subspecies better adapt new environment.
