植物的生长策略之间的权衡，使适应最佳的增长在一个条件下可能会排除在另一个最佳的增长。因此，我们预测，一个植物物种，积极响应一个全球变化的治疗将不太可能比平均积极响应另一个治疗，特别是对治疗，有利于不同的性状。我们研究了植物物种丰度在39个全球变化实验操纵两个或更多的以下：二氧化碳，氮，磷，水，温度，或干扰。总体而言，一个物种对一种治疗的定向反应比预期的可能性高13%，反对其对另一种单因素治疗的反应。这种趋势在整个全球数据集中均可检测到，但对单个治疗组合或单个实验的预测能力很小。虽然在应对不同全球变化处理方法的能力方面的权衡产生了明显的全球影响，但其他力量掩盖了它们在地方社区的影响。本文受版权保护。All rights reserved.

Plants are subject to tradeoffs among growth strategies such that adaptations for optimal growth in one condition can preclude optimal growth in another. Thus, we predicted that a plant species that responds positively to one global change treatment would be less likely than average to respond positively to another treatment, particularly for pairs of treatments that favor distinct traits. We examined plant species abundances in 39 global change experiments manipulating two or more of the following: CO2 , nitrogen, phosphorus, water, temperature, or disturbance. Overall, the directional response of a species to one treatment was 13% more likely than expected to oppose its response to a another single-factor treatment. This tendency was detectable across the global dataset but held little predictive power for individual treatment combinations or within individual experiments. While tradeoffs in the ability to respond to different global change treatments exert discernible global effects, other forces obscure their influence in local communities.
