“…This is in accordance with previous studies carried out under elevated CO 2 [47][48][49][50]. Plants lose the ability to take up soil nitrate (most common form of nitrogen) and convert it into organic compounds such as proteins at enriched CO 2 conditions.…”

Response of two important tropical tree species of Meliaceae (Azadirachta indica -neem and Melia dubiamelia) to elevated levels of CO2 (600 and 900 ppm) under simulated temperature and moisture regimes in Automated Open Top Chambers was studied. Growth, biochemical changes, antioxidant property and gas exchange parameters were estimated. The results indicate that A. indica is expected to acclimatize under elevated CO2 concentrations whereas M. dubia was observed to be a species sensitive to elevated CO2 concentrations, affecting the photosynthetic machinery, stomatal conductance and transpiration and a subsequent decrease in carbohydrates, proteins, sugars, amino acids and phenolics. The short-term and long-term responses with respect to stomatal conductance and transpiration rates were higher in neem than melia. Thus, a positive response of neem to increased CO2 concentrations is a good indication for its future establishment in potentially changed climatic conditions.

“…As global climate warms, increasingly warmer springs may combine with the random climatological occurrence of advective freezes, which result from cold air moving from one region to another, to dramatically increase the future risk of false springs, with profound ecological and economic consequences [e.g., Gu et al, 2008;Marino et al, 2011;Augspurger, 2013]. For example, in the false spring of 2012, an event embedded in long-term trends toward earlier spring [e.g., Schwartz et al, 2006], the frost damage to fruit trees totaled half a billion dollars in Michigan alone, prompting the federal government to declare the state a disaster area [Knudson, 2012].…”

Phenology—the study of recurring plant and animal life cycle stages, especially their timing and relationships with weather and climate—is becoming an essential tool for documenting, communicating, and anticipating the consequences of climate variability and change. For example, March 2012 broke numerous records for warm temperatures and early flowering in the United States [Karl et al., 2012; Elwood et al., 2013]. Many regions experienced a “false spring,” a period of weather in late winter or early spring sufficiently mild and long to bring vegetation out of dormancy prematurely, rendering it vulnerable to late frost and drought.

“…This 'paradox' has been documented for spring frost stress over forest (Auspurger, 2013;Rigby and Porporato, 2008;Rammig et al, 2010) and wheat crop (Gu et al, 2008;Zheng et al, 2015) but to our knowledge few results concern winter frost stress over forest (Hänninen, 2006) and crops. Spring frost impact is for wheat attributable to the more rapid advance in development of crops to sensitive stages than the advance in last frost date (Zheng et al, 2015).…”

-Pea (Pisum sativum L.) is an important crop in temperate regions for its high seed protein concentration that is particularly sensitive to abiotic stresses. The abrupt temperature increase known as the "1987/1988 temperature regime shift" that occurs over Europe is questioning how winter pea will perform in the changing climate. This study assessed the winter frost damage evolution along from 1961 to 2015 in Burgundy-Franche-Comté by using: (1) daily observed and gridded regional temperature data and (2) a validated crop winter frost stress model calibrated for pea. This study shows a global decrease of the frost stress nevertheless resulting from a subtle balance between the decrease in its intensity and the increase of the number of events. The frost stress evolution patterns with warming depend on both plant frost resistance level and acclimation rate and are still sensitive to winter climate fluctuations. This study provides relevant information for breeding performant winter crop ideotypes able to moderate detrimental effects of climate change and offering new cropping opportunities in temperate regions.
