分析气候变化对这些现象学转变的影响.

主要方法:

2001-2020年利用气候和规范差异植被指数 (NDVI) 数据.
分析了赛季开始 (SOS),赛季结束 (EOS) 和赛季长度 (LOS) 的趋势.
研究了温度变化 (Tmax,Tmin) 对现象时间的影响.

主要成果:

由于较早的SOS (-0.50天/年) 和延迟的EOS (+0.38天/年),植被生长季节显著延长 (0.88天/年).
温暖的冬季/春季温度推进了SOS;温暖的夏季/秋季推迟了EOS.
白天的最高温度 (Tmax) 对推进SOS的影响比最低温度 (Tmin) 更大.
八月Tmin显著延迟了EOS,而八月Tmax没有.

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.

Responses to Drought and Flooding

Responses to Drought and Flooding

Water plays a significant role in the life cycle of plants. However, insufficient or excess of water can be detrimental and pose a serious threat to plants.

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.

Biological Clocks and Seasonal Responses

Biological Clocks and Seasonal Responses

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Responses to Salt Stress

Responses to Salt Stress

Salt stress—which can be triggered by high salt concentrations in a plant’s environment—can significantly affect plant growth and crop production by influencing photosynthesis and the absorption of water and nutrients.

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.
