The global soil community and its influence on biogeochemistry

open access: yesScience, 2019
Microbes' role in soil decomposition Soils harbor a rich diversity of invertebrate and microbial life, which drives biogeochemical processes from local to global scales.

Regionally disparate ecological responses to microplastic slowing of faecal pellets yields coherent carbon cycle response

open access: yesFrontiers in Marine Science, 2023
Microplastic is a ubiquitous marine pollutant whose small dimensions make it biologically available to phytoplankton and zooplankton. These organisms are crucial as the basis of the marine food web and for the export of organic material in the form of ...

Investigating controls on sea ice algal production using E3SMv1.1-BGC

open access: yesAnnals of Glaciology, 2020
We present the analysis of global sympagic primary production (PP) from 300 years of pre-industrial and historical simulations of the E3SMv1.1-BGC model.

Ocean acidification and warming modify stimulatory benthos effects on sediment functioning: An experimental study on two ecosystem engineers

open access: yesFrontiers in Marine Science, 2023
Many macrofauna have a stimulatory effect on sediment functioning through their burrowing, feeding and irrigation activities. Here, we investigated the single and combined effect of ocean acidification and warming on the stimulatory effect of two key ...

The consequences of climate change for dryland biogeochemistry.

open access: yesNew Phytologist, 2022
Drylands, which cover more than 40% of Earth's terrestrial surface, are dominant drivers of global biogeochemical cycling and home to more than one third of the human population.

Concentrations and Fractionation of Carbon, Iron, Sulfur, Nitrogen and Phosphorus in Mangrove Sediments Along an Intertidal Gradient (Semi-Arid Climate, New Caledonia)

open access: yesJournal of Marine Science and Engineering, 2015
In mangrove ecosystems, strong reciprocal interactions exist between plant and substrate. Under semi-arid climate, Rhizophora spp. are usually predominant, colonizing the seashore, and Avicennia marina develops at the edge of salt-flats, which is the ...

Physical and biogeochemical drivers of solute mobilization and flux through the critical zone after wildfire

open access: yesFrontiers in Water, 2023
A nine-year time series of nutrient cation and anion concentration and efflux from three forested catchments in the Jemez River Basin Critical Zone Observatory (JRB-CZO) in northern New Mexico was used to quantify the pulse of chemical denudation ...

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 229-246., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Influence of effluents from a Wastewater Treatment Plant on nutrient distribution in a coastal creek from southern Brazil

open access: yesBrazilian Archives of Biology and Technology, 2008
The hypothesis that effluents treated through activated sludge process cause changes in nutrient biogeochemistry of receiving water bodies was investigated in Vieira creek, southern Brazil.
