Warming accelerates the decomposition of root-derived hydrolysable lipids in a temperate forest and is depth- and compound class-dependent Open
Global warming could potentially increase the decomposition rate of soil organic matter (SOM), not only in the topsoil (20 cm). Despite its low carbon content, subsoil holds on average nearly as much SOM as topsoil across various ecosystem…

Biochemical and biophysical drivers of the hydrogen isotopic composition of carbohydrates and acetogenic lipids Open
The hydrogen isotopic composition (δ 2 H) of plant compounds is increasingly used as a hydroclimatic proxy; however, the interpretation of δ 2 H values is hampered by potential coeffecting biochemical and biophysical processes. Here, we st…
