We conducted a detailed investigation of U isotopes in conjunction with a broad geochemical investigation during field-scale biostimulation and desorption experiments. This investigation was carried out in the uranium-contaminated alluvial aquifer of the Rifle field research site. In this well-characterized setting, a more comprehensive understanding of U isotope geochemistry is...
Grasslands account for a large proportion of global terrestrial productivity and play a critical role in carbon and water
cycling. Within grasslands, photosynthetic pathway is an important functional trait yielding different rates of productivity
along environmental gradients. Recently, C₃-C₄ sorting along spatial environmental gradients has been reassessed by
controlling for...

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 used to constrain the flux and attenuation of terrestrial...
AIM: C₄ photosynthesis is an adaptation that maintains efficient carbon assimilation in warm and low-CO₂ conditions. Due to the importance of C₄ grasses for carbon and surface energy fluxes numerous models have been proposed to describe their spatial distribution and forecast responses to climate change. These models often rely on...
A previous study showed that ammonia oxidation by the Thaumarchaeota Nitrosopumilus maritimus (group 1.1a) was resistant
to concentrations of the C₈ 1-alkyne, octyne, which completely inhibits activity by ammonia-oxidizing bacteria. In this study, the
inhibitory effects of octyne and other C₂ to C₁₀ 1-alkynes were evaluated on the nitrite production...

The placement of ‘Pseudomonas butanovora’ in the genus Thauera was proposed previously, based on 16S rRNA gene sequence analysis, upon further studies of taxonomical characteristics. In this study, physiological characteristics and DNA–DNA reassociation data are presented and the transfer of ‘P. butanovora’ to the genus Thauera is proposed. The original...
