Glycerol dialkyl glycerol tetraethers (GDGTs) are membrane-spanning lipids from Bacteria
and Archaea that are ubiquitous in a range of natural archives and especially abundant in …

Molecular biomarkers are becoming increasingly important tools in paleoenvironmental
research, and over recent years have been shown to be useful indicators of human …

Triterpenoids and their derivatives are ubiquitous in sediment samples. Land plants are
major sources of nonhopanoid triterpenoids; these terpenoids comprise a vast number of …

Chinese grasslands hold a third of the national soil organic carbon (OC) stocks but remain
poorly investigated in terms of soil molecular components and their distribution patterns …

Digital soil mapping (DSM) is commonly conducted using input soil attributes derived from
laboratory analyses of geographically referenced samples. Field observations are often …

Paleoenvironmental studies previously performed on Lake Igaliku revealed two
agropastoral phases in south Greenland: the Norse settlement from AD 986 to ca. AD 1450 …

Abstract The Sanetti Plateau is Africa's largest Afro-alpine ecosystem. As part of an ongoing
effort to reconstruct the paleo-extent of Ericaceous vegetation in this ecosystem, we aim to …

Realizing the potential of terpenoid biomarkers as an unequivocal land ecosystem and floral
diversity indicator calls for work to establish a direct link between the terpenoids extracted …

As the primary producer in terrestrial ecosystems, plants are the ultimate source of organic
carbon supplied into soils and fueling microbial decomposition. Hence, plants play a key …

In order to fill the need for specific and stable tracers for monitoring the degradative state of
particulate organic matter (OM), betulin and its degradation products were selected to trace …
