摘要了解调节碳循环的生物地球化学过程是减少大气二氧化碳排放的核心。活的有机体的作用已经被考虑,但传统上的重点一直是植物和微生物的贡献。我们认为,要使碳循环完全“活跃起来”,需要更广泛地考虑动物在调节生物地球化学过程中的功能作用,并量化它们对陆地和水生水库与大气之间的碳储存和交换的影响。为了鼓励更多的假设驱动的实验研究,量化动物的影响,我们讨论了动物可能影响生态系统和大气内部和之间的碳交换和储存的机制。我们说明了这些机制如何导致乘数效应,其幅度可能与目前碳预算中使用的更传统的碳储存和汇率估计相媲美。许多动物物种已经被直接管理。因此,提高对其对碳预算影响的量化了解可能会为管理层和政策提供机会,以确定和实施新的备选方案,在区域范围内减轻二氧化碳排放。
AbstractUnderstanding the biogeochemical processes regulating carbon cycling is central to mitigating atmospheric CO2emissions. The role of living organisms has been accounted for, but the focus has traditionally been on contributions of plants and microbes. We develop the case that fully “animating” the carbon cycle requires broader consideration of the functional role of animals in mediating biogeochemical processes and quantification of their effects on carbon storage and exchange among terrestrial and aquatic reservoirs and the atmosphere. To encourage more hypothesis-driven experimental research that quantifies animal effects we discuss the mechanisms by which animals may affect carbon exchanges and storage within and among ecosystems and the atmosphere. We illustrate how those mechanisms lead to multiplier effects whose magnitudes may rival those of more traditional carbon storage and exchange rate estimates currently used in the carbon budget. Many animal species are already directly managed. Thus improved quantitative understanding of their influence on carbon budgets may create opportunity for management and policy to identify and implement new options for mitigating CO2release at regional scales.
