摘要

营养稀释(ND)--植物组织中营养元素浓度的降低--源于碳水化合物质量的增加和/或 20 多种必需元素的减少。二氧化碳含量的增加及其对生物量的促进作用与营养稀释有关。我们认为,营养稀释是全球食草动物数量下降的主要驱动因素。食草动物必须从营养贫乏的植物组织中获取富含元素的动物组织,而它们的数量通常会随着宏量和微量营养元素的增加而增加。我们预测,养分稀释对全球的影响将在地球上一些生物多样性最丰富、生产力最高和/或养分最贫乏的生态系统中放大,并将有利于食草动物的特定特征,包括吸食汁液和反刍微生物群。

Nutrient dilution and the future of herbivore populations.

Nutrient dilution (ND) - the decrease in the concentration of nutritional elements in plant tissue - arises from an increase in the mass of carbohydrates and/or a decrease in the 20+ essential elements. Increasing CO2 levels and its promotion of biomass are linked to nutrient dilution. We build a case for nutrient dilution as a key driver in global declines in herbivore abundance. Herbivores must build element-rich animal tissue from nutrient-poor plant tissue, and their abundance commonly increases with fertilization of both macro- and micronutrients. We predict the global impacts of nutrient dilution will be magnified in some of Earth's most biodiverse, highly productive, and/or nutrient-poor ecosystems and should favor specific traits of herbivores, including sap-feeding and ruminant microbiomes.

期刊介绍: Trends in Ecology & Evolution (TREE) is a comprehensive journal featuring polished, concise, and readable reviews, opinions, and letters in all areas of ecology and evolutionary science. Catering to researchers, lecturers, teachers, field workers, and students, it serves as a valuable source of information. The journal keeps scientists informed about new developments and ideas across the spectrum of ecology and evolutionary biology, spanning from pure to applied and molecular to global perspectives. In the face of global environmental change, Trends in Ecology & Evolution plays a crucial role in covering all significant issues concerning organisms and their environments, making it a major forum for life scientists.
