南北气候梯度导致树木休眠解除的适应性变化
[目的]全球变暖正在对全球植物物候和活力产生前所未有的影响,可能导致食物网、碳、水循环和生态系统功能发生重大变化。前期对温带树木中的广泛研究表明,主要是秋末和冬季的低温(chilling)、冬末和春季的高温(forcing)和光周期驱动植物的春季物候,但这些因素很少在亚热带森林中得到研究,因此它们的潜在影响相对未知,并且亚热带树种和温带树种的具体差异也尚不明确。同时,目前对于相关内容在地理和气候梯度上的种间变异了解甚少。[方法]本研究通过分析中国…查看全部>>
[Objective]Global warming is having unprecedented effects on plant phenology and vigor worldwide,potentially leading to major changes in food webs,carbon and water cycles,and ecosystem function.Extensive previous research in temperate trees has shown that cold temperatures(chilling)in late fall and winter,high temperatures(forcing)in late winter and spring,and photoperiod drive spring phenology in plants,but these factors have rarely been studied in subtropi…查看全部>>
