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

When a range-shifting species colonizes an ecosystem it has not previously inhabited, it may experience suboptimal conditions that challenge its continued persistence and expansion. Some impacts may be partially mitigated by artificial habitat analog

Plant wax lipids and lignin phenols are the two most common classes of molecular markers that are used to trace vascular plant-derived OM in the marine environment. However, their 13C and 14C compositions have not been directly compared, which can be

Materials collected by sediment traps over a 3-y period and sedimentary horizons from a gravity core covering the last 6000 y were used to investigate the effects of climate-related processes such as wind-driven upwelling and regional rainfall on the

Seven strains of marine aerobic anoxygenic phototrophs belonging to the genus Erythrobacter were isolated. The strains were characterized regarding their physiological and biochemical properties, 16S rDNA and pufM gene sequences, morphological featur

The distributions of n-alkanes of four species of Micromeria have the conventional higher plant pattern of high carbon preference index (CPI) and odd-numbered carbon dominance (maxima at n-C31 or n-C33), rather than the even-numbered predominance pre

Hydrous pyrolysis experiments were conducted at 125 to 375°C and 350 bars to constrain factors that regulate the generation and relative abundance of hydrocarbon and nonhydrocarbon gases during thermal maturation of Monterey, Eutaw, and Smackover sh

Organic carbon (OC) from multiple sources can be delivered contemporaneously to aquatic sediments. The influence of different OC inputs on carbon-14–based sediment chronologies is illustrated in the carbon-14 ages of purified, source-specific (biom
