From Points to Landscapes: Measuring and Scaling Up Methane Emissions From Mound-Building Termites.

内容摘要

Termites represent a critical but poorly constrained source in the global methane (CH4) budget. This commentary addresses the "scaling paradox" highlighted by Yatsko et al. (2026), demonstrating that the primary drivers of CH4 emissions shift dramatically between individual species, single mounds, and broader landscapes. We expand on this framework using field data from massive Macrotermes mounds in South Africa, which reveals complex intra-mound spatial heterogeneity. Furthermore, expansive subterranean foraging networks frequently flip surrounding matrix soils from net methane sinks into localized emission sources. To resolve this scaling paradox and account for such spatial variation, we propose integrating traditional emission factors with multi-scale technologies to accurately map and model termite CH4 dynamics.
