The paper quantifies internal tree decay using tomography in a temperate forest, finding species and site differences in decay prevalence and severity.

This study compares methane emissions from upland and wetland trees, finding wetland trees emit 40 times more methane due to hydrological and species-specific factors, while upland emissions show little environmental control.

The paper measures methane fluxes and microbial communities in upland forest trees and soils, finding widespread methanogenesis in wood and its role in net methane emissions.

The paper explores the microbiome within living trees, revealing distinct microbial communities in heartwood and sapwood, and highlights their ecological significance.

This paper develops an optimized method for sampling and analyzing the wood microbiome, demonstrating its effectiveness for detecting methane-cycling microbes in various tree species.
