The hydrocarbon fractions of three species of Achillea L. have been analysed by capillary gas chromatography (GC) and GC-mass spectrometry(GC-MS) and were shown to consist of the conventional, odd-carbon number dominant distributions of n-alkane homo

In 1936 a German chemist identified certain organic molecules that he had extracted from ancient rocks and oils as the fossil remains of chlorophyll--presumably from plants that had lived and died millions of years in the past. It was another twenty-
Vegetation reconstructions based on pollen and plant macrofossils show that there was a global reduction in forest at the last glacial maximum compared with preindustrial times. Open vegetation types including tundra, steppe and grassland expanded. T

Atmospheric CO2 concentration is hypothesized to influence vegetation distribution via tree–grass competition, with higher CO2 concentrations favouring trees. The stable carbon isotope (δ13C) signature of vegetation is influenced by the relative i

We summarize the applications of molecular proxies in paleoclimatology. Marine molecular records especially are proving to be of value but certain environmentally persistent compounds can also be measured in lake sediments, loess deposits and ice cor

Grasses (Poaceae) are distributed across the world in broad latitudinal belts and are an important source of C4 biomass in the geological record of soils as well as lake and marine sediments. We examined long-chain leaf wax components of thirty-five

High resolution records for long chain n-alkane and n-alkanol biomarkers have been obtained by extraction of sediments from the profiles of Luochan (0–36 ka) and Xunyi (0–170 ka) on the Chinese Loess Plateau (CLP). The two records are similar whe
