The large difference in the fractionation of stable carbon isotopes between C3 and C4 plants is widely used in vegetation reconstructions, where the predominance of C3 plants suggests wetter and that of C4 plants drier conditions. The stable carbon i

Abstract Background The economic value of ginseng in the global medicinal plant trade is estimated to be in excess of US$2.1 billion. At the same time, the evolutionary placement of ginseng (Panax ginseng) and the complex evolutionary history of the

The leaf photosynthesis models developed by Farquhar et al. (1980) (FvCB) and Goudriaan et al. (1985) (G85) are both used in Earth system and weather models to quantify ecosystem carbon assimilation. Despite their common role, a systematic comparison

We present a reconstruction of the change in climatic humidity around the Mediterranean between 3000–1000 yr BP. Using a range of proxy archives and model simulations we demonstrate that climate during this period was typified by a millennial-scale

Terrestrial vegetation influences climate by modifying the radiative-, momentum-, and hydrologic-balance. This paper contributes to the ongoing debate on the question whether positive biogeophysical feedbacks between vegetation and climate may lead t

The corms of different Hypoxis species (Hypoxidaceae) are used for the treatment and management of a variety of human ailments and disorders in African traditional medicine. However, the used corms are morphologically similar and it is not known whet

In Tanzania, about 10% of the reported 12,000 species of higher plants are estimated to be used as medicine for treating different human health problems. Most of the medicinal plants are collected from wild populations, but their trade and quantities

The proton chemical shifts and coupling constants in the isomeric dihydrofurans and dihydrothiophenes have been determined using the proton-proton decoupling technique, where necessary. The coupling constants in both 2,5-dihydro-compounds were found

Methyl malonate (A), methyl succinate (B), methyl glutarate (C) and methyl 3-oxocyclobutanecarboxylate (D) are formed from diazomethane and carbon suboxide in the presence of methanol. A mechanism is proposed for this reaction.
