Influence of Ecological Restoration on Mercury Mobility and Microbial Activities on Former Guyanese Mining Sites

Applied Sciences, 2021
As rehabilitation efforts in Guyana are recent, there is little information on the effect of different ecological rehabilitation protocols for Guyana’s mining sites on biogeochemical cycles and mercury mobility.

Biogas production from Opuntia stricta Haw.: microbial diversity and solid load influence on sludge recycle systems

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The search for alternative and sustainable energy sources becomes urgent as energy demand increases and fossil fuels become less available, especially in water‐scarce regions such as the Brazilian semi‐arid region, where current projections of global warming and the expansion of arid and semi‐arid zones point to a future of desertification ...

Biodegradation of MC252 oil in oil:sand aggregates in a coastal headland beach environment

Frontiers in Microbiology, 2014
Biodegradation potential of MC252 in oil:sand aggregates, termed surface residue balls (SRBs), was examined using multiple lines of evidence on a heavily-impacted coastal headland beach in Louisiana, USA.

Pathway-Centric Analysis of Microbial Metabolic Potential and Expression Along Nutrient and Energy Gradients in the Western Atlantic Ocean

Frontiers in Marine Science, 2022
Microbial communities play integral roles in driving nutrient and energy transformations in the ocean, collectively contributing to fundamental biogeochemical cycles. Although it is well known that these communities are stratified within the water column,

Modeling the impacts of grazing management on livestock behavior and performance: A case study in the Peruvian Andes

Grassland Research, EarlyView.
Our modeling study shows that livestock management strongly influences grazing behavior and animal performance in the Peruvian Andes. Furthermore, adjusting stocking rates and improving animal distribution can enhance forage intake and body condition while increasing forage biomass.

Yellowstone Wildfires Increased Stream Ion Concentrations and Export

Nitrogen
Wildfires in the western U.S. have increased in severity and duration in recent decades. Severe wildfires can enhance the rates of nutrient mineralization, causing large exports of inorganic nitrogen and other ions from forests to streams.

Multiple sulfur isotope signatures of sulfite and thiosulfate reduction by the model dissimilatory sulfate-reducer, Desulfovibrio alaskensis str. G20

Frontiers in Microbiology, 2014
Dissimilatory sulfate reduction serves as a key metabolic carbon remineralization process in anoxic marine environments. Sulfate reducing microorganisms can impart a wide range in mass-dependent sulfur isotopic fractionation.

Quantifying Effects of OM–Cation Interactions on Mid‐Infrared FTIR Absorption Spectra of Polygalacturonic Acid

Journal of Plant Nutrition and Soil Science, EarlyView.
The composition of organic matter (OM) was explained by effects of OM–cation interactions using polygalacturonic acid (PGA) as model substance. These effects were analyzed by COO− absorption bands in mid‐FTIR spectra. The change in intensity and wavenumber ranges of COO− bands in FTIR was quantified.
