Producer Nutritional Quality Controls Ecosystem Trophic Structure

We compiled an unparalleled data set from the literature and other sources that includes measures of aboveground producer biomass, herbivore biomass, and producer nutritional quality expressed as nitrogen and phosphorus content in aboveground producer biomass (i.e. % of producer dry weight) for a broad range of aquatic and terrestrial ecosystems. The data compiled correspond to mean values that integrate the whole ecosystem over at least one year of observations.

本研究从文献及其他渠道汇编得到一套前所未有的数据集，涵盖地上生产者生物量、植食动物生物量，以及以地上生产者生物量中的氮、磷含量（即占生产者干重百分比）表征的生产者营养品质相关指标，覆盖各类水生与陆地生态系统。所汇编的数据均为整合了至少一年观测周期的全生态系统平均值。
