概括

苏格兰松树 (Pinus sylvestris) 的气候敏感性发生了变化,特别是在最小密度,影响了树枝气候学. 这项研究探讨了树环密度参数,以更好地了解气候变化反应.

科学领域:

登德罗年代学和气候科学
生态学和进化生物学.
林业和环境科学林业和环境科学

背景情况:

松树 (Pinus sylvestris) L. 是欧亚大陆树状气候学重建的关键物种.
传统的方法依赖于树环宽度 (TRW) 和最大松木密度 (MXD).
早期木材/后期木材密度 (EWD/LWD) 和最小密度 (MND) 的气候信号尚未得到充分探索.

研究的目的:

调查多个P的气候变化反应. sylvestris 树环参数.树环参数是指树环的参数.树环参数是指树环的参数.
为了比较这些响应在苏格兰和瑞典的两个对比的地方.
评估EWD/LWD和MND在树枝气候学重建方面的技能.

主要方法:

分析了来自苏格兰和瑞典的树环密度数据.
树环参数 (LWD,MXD,MND) 与温度数据之间的相关性分析.
研究气候与生长关系的时间变化.

主要成果:

七月,八月和六月至八月季节的LWD和MXD与温度 (0.50.7) 的相关性最强.
在瑞典数据中发现了MND和7月气温之间的显著负相关性,自20世纪末以来一直在减少.
北苏格兰的地点显示没有可比的逆MND温度信号,表明特定地点的生理变化.

结论:

气候敏感度为P.P. sylvestris已经发生了变化,最小密度发生了变化.
MXD的稳定性与MND的变化形成鲜明对比,凸显了需要额外的密度参数的需要.
改变树木生长的敏感性可能会降低来自北欧地区的气候重建代理的有效性.

Responses to Heat and Cold Stress

Responses to Heat and Cold Stress

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

Adaptations that Reduce Water Loss

Adaptations that Reduce Water Loss

Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

Global Climate Change

Global Climate Change

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.
