Iron/Manganese Oxide‐Bound Nitrogen Suppresses Microbial Mediated Nitrate Reduction in Soil

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Nitrogen cycling plays a pivotal role in sustaining ecosystem productivity and stability, while the chemical forms of nitrogen in soils critically influence both its efficiency and pathways. In this study, farmland soils from the Anning River Basin—an important watershed in Southwest China—were investigated to examine the regulatory effects of

Integrating and assessing metacommunity drivers of ecosystem function and resilience in benthic algal systems

open access: yesOikos, EarlyView.
Understanding the scales and mechanisms by which species composition interacts with ecosystem functions is critical for forecasting the effects of environmental perturbations on ecosystem services. However, the linkages between what regulates the ecosystem functions of dispersal‐capable networks of communities (metacommunities) and what regulates a ...

Is Bitcoin’s Carbon Footprint Persistent? Multifractal Evidence and Policy Implications

open access: yesEntropy, 2022
The Bitcoin mining process is energy intensive, which can hamper the much-desired ecological balance. Given that the persistence of high levels of energy consumption of Bitcoin could have permanent policy implications, we examine the presence of long ...
