Ongoing alterations to Earth’s biogeochemical cycles (e.g., via fertilization, burning of fossil fuels, and pollution) are expected to impact plants, plant consumers and all subsequent trophic levels. While fertilization experiments often reveal arthropod nutrient limitation by nitrogen and phosphorus via effects on plant nutrient density and biomass, these macronutrients are only two of many nutrients important to arthropod fitness. Micronutrients are key to osmoregulation and enzyme function and can interact synergistically with macronutrients to shape the geography of arthropod abundance. We examine arthropod response to macro‐ and micronutrient fertilization as a function of nutrient type, application amount, duration, frequency, and plant responses to fertilization with the goal of addressing how ongoing alterations to biogeochemical cycles will shape future grassland food webs.

在草地节肢动物丰度的荟萃分析中，微量营养素增强了宏观营养素的作用

预计地球生物地球化学循环的持续变化（例如，通过施肥，燃烧化石燃料和污染）将影响植物，植物消费者和所有随后的营养水平。施肥实验通常通过影响植物养分密度和生物量揭示出氮和磷限制了节肢动物的养分，但这些大量养分只是对节肢动物适应性重要的许多养分中的两种。微量营养素是渗透调节和酶功能的关键，可以与大量营养素协同作用，从而塑造节肢动物的丰满地理。我们研究了节肢动物对大量和微量营养素施肥的反应，它与营养素类型，施用量，持续时间，频率，
