近日，比利时根特大学Pieter Sanczuk及其团队成员最新的研究揭示，欧洲森林植物意外的西移与氮沉积有关。该研究于2024年10月11日发表于国际一流学术期刊《科学》杂志上。

据了解，气候变化通常被认为是导致物种向两极转移的原因。然而，其他环境变化可能会以意想不到的方式影响物种的地理分布。

研究人员量化了欧洲森林植物分布的多年代际变化，并将这些变化与森林生物多样性变化的关键驱动因素联系起来——气候变化、大气沉积(氮和硫)和森林冠层动态。

令人惊讶的是，向西迁移的可能性是向北迁移的2.6倍。氮介导的殖民地化而不是气候变化，可能是由过去酸化沉积的恢复所促进，是解释向西移动最好的理由。

研究结果强调，生物多样性再分配模式似乎很复杂，更有可能是由几种环境变化之间的相互作用，而不是单独由气候变化的排他性影响所驱动的。

Abstract: Climate change is commonly assumed to induce species’ range shifts toward the poles. Yet, other environmental changes may affect the geographical distribution of species in unexpected ways. Here, we quantify multidecadal shifts in the distribution of European forest plants and link these shifts to key drivers of forest biodiversity change: climate change, atmospheric deposition (nitrogen and sulfur), and forest canopy dynamics. Surprisingly, westward distribution shifts were 2.6 times more likely than northward ones. Not climate change, but nitrogen-mediated colonization events, possibly facilitated by the recovery from past acidifying deposition, best explain westward movements. Biodiversity redistribution patterns appear complex and are more likely driven by the interplay among several environmental changes than due to the exclusive effects of climate change alone.
