biogeochemistry is a useful tool for assessing geochemical dispersion patterns. sari gunay epithermal gold deposit was selected in order to assess the application of biogeochemical exploration for gold in northwestern iran. in this study, four sites were sampled in a profile perpendicular to mineralized vein with a control site two km far-off mineralized vein. a sample from each dominant plant ...

biogeochemical investigation on s. orientalis, a flora growing on the soils derived from serpentinized dunite in the forumad area, sabzevar ophiolite has been conducted in order to examine the plant-soil relationship in chromite prospecting. due to engagement of cr in the chromite crystal structure and its non-essential role in the plant’s life cycle, ni was used as pathfinder element in biogeo...

Biogeochemistry is at the dawn of an era in which molecular advances enable the discovery of novel microorganisms having unforeseen metabolic capabilities, revealing new insight into the underlying processes regulating elemental cycles at local to global scales. Traditionally, biogeochemical inquiry began by studying a process of interest, and then focusing downward to uncover the microorganism...

Microorganisms are the most abundant lifeform on Earth, mediating global fluxes of matter and energy. Over the past decade, high-throughput molecular techniques generating multiomic sequence information (DNA, mRNA, and protein) have transformed our perception of this microcosmos, conceptually linking microorganisms at the individual, population, and community levels to a wide range of ecosystem...

SHIMMER (Soil biogeocHemIcal Model for Microbial Ecosystem Response) is a new numerical modelling framework designed to simulate microbial dynamics and biogeochemical cycling during initial ecosystem development in glacier forefield soils. However, it is also transferable to other extreme ecosystem types (such as desert soils or the surface of glaciers). The rationale for model development aris...

Accurate identification of nitrate (NO3−) sources is critical to addressing groundwater pollution, especially in highly vulnerable karst aquifers. The hydrochemistry and δ15NNO3 δ18ONO3 isotopes were analyzed samples taken from the Jinan Spring Catchment, which has been affected by urbanization agricultural activities. study highlighted use hydrochemistry, environmental isotopes, a multisource ...

Much research has focused on improving ecosystem models by incorporating microbial regulation of biogeochemistry. However, models still struggle to predict biogeochemical function in future scenarios linked to accelerating global environmental change. Ecological mechanisms may influence the relationship between microbial communities and biogeochemistry, and here, we show that stochastic dispers...
