近日，Catherine H. Graham及其小组揭示了陆生脊椎动物持续的能量多样性关系。这一研究成果发表在2025年7月3日出版的国际学术期刊《科学》上。

课题组认为，这种不一致是由混淆的地理影响造成的，这些影响掩盖了物种丰富度和能源相关因素之间的真正关系。通过比较不同气候条件下的物种丰富度，研究人员将温度、降水和初级生产力的直接影响与各种气候的面积和隔离的混杂影响区分开来。通过对陆生脊椎动物的全球分析，课题组揭示了能量相关因子与物种丰富度之间清晰一致的关系。他们的发现澄清了现有的生态学理论，阐明了采用气候空间视角如何推进生物多样性研究，为生物多样性模式及其对环境变化的响应提供了重要见解。

据了解，生态学家早就提出，提供更多能量的环境可以支持更多的物种，然而经验证据经常与这一预期相矛盾。

Abstract: Ecologists have long proposed that environments providing more energy can support more species, yet empirical evidence frequently contradicts this expectation. We argue that such inconsistencies result from confounding geographical influences that mask the true relationship between species richness and energy-related factors. Here, by comparing species richness across different climate conditions, we disentangle the direct effects of temperature, precipitation, and primary productivity from the confounding impacts of the area and isolation of various climates. Using a global analysis of terrestrial vertebrates, we reveal clear and consistent relationships between energy-related factors and species richness. Our findings clarify existing ecological theory and illustrate how adopting a climate space perspective advances biodiversity research, providing critical insights into biodiversity patterns and their responses to environmental change.
