Abstract

Beyond the better-studied carbohydrates and the macronutrients nitrogen and phosphorus, a remaining 20 or so elements are essential for life and have distinct geographical distributions, making them of keen interest to ecologists. Here, I provide a framework for understanding how shortfalls in micronutrients like iodine, copper, and zinc can regulate individual fitness, abundance, and ecosystem function. With a special focus on sodium, I show how simple experiments manipulating biogeochemistry can reveal why many of the variables that ecologists study vary so dramatically from place to place. I conclude with a discussion of how the Anthropocene's changing temperature, precipitation, and atmospheric CO2 levels are contributing to nutrient dilution (decreases in the nutrient quality at the base of food webs). Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 52 is November 2021.

元素周期表的无形之手:微量元素如何塑造生态
除了研究得比较透彻的碳水化合物和大量营养元素氮和磷之外,还有大约20种元素是生命所必需的,它们具有不同的地理分布,使它们成为生态学家的浓厚兴趣。在这里,我提供了一个框架来理解像碘、铜和锌这样的微量营养素的缺乏是如何调节个体健康、丰度和生态系统功能的。通过对钠的特别关注,我展示了操纵生物地球化学的简单实验如何揭示了生态学家研究的许多变量在不同地方差异如此之大的原因。最后,我讨论了人类世不断变化的温度、降水和大气二氧化碳水平是如何导致营养物质稀释的(食物网底部营养物质质量的降低)。预计《生态、进化和分类学年度评论》第52卷的最终在线出版日期为2021年11月。修订后的估计数请参阅http://www.annualreviews.org/page/journal/pubdates。

期刊介绍: The Annual Review of Ecology, Evolution, and Systematics is a scholarly publication that has been in circulation since 1970. It focuses on important advancements in the areas of ecology, evolutionary biology, and systematics, with relevance to all forms of life on Earth. The journal features essay reviews that encompass various topics such as phylogeny, speciation, molecular evolution, behavior, evolutionary physiology, population dynamics, ecosystem processes, and applications in invasion biology, conservation, and environmental management. Recently, the current volume of the journal transitioned from a subscription-based model to open access through the Annual Reviews' Subscribe to Open program. Consequently, all articles published in the current volume are now available under a CC BY license.
