DOI: 10.1002/2017gl076253
Abstract: Variations in terrestrial oxygen-isotope reconstructions from ice cores and speleothems have been primarily attributed to climatic changes of surface air temperature, precipitation amount, or atmospheric circulation. Here we demonstrate with the fully coupled isotope-enabled Community… read more here.

DOI: 10.1002/ajb2.1183
Abstract: PREMISE OF THE STUDY The Hymenochaetales are dominated by lignicolous saprotrophic fungi involved in wood decay. However, the group also includes bryophilous and terricolous taxa, but their modes of nutrition are not clear. Here, we… read more here.

DOI: 10.1002/cbic.202300056
Abstract: Plants of the genus Allium such as chives, onions or garlic produce S‐alk(en)yl cysteine sulfoxides as flavor precursors. Two major representatives are S‐propenyl cysteine sulfoxide (isoalliin) and S‐propyl cysteine sulfoxide (propiin), which only differ by… read more here.
