Adoption of Minimum Tillage and Mid‐Season Drainage in Rice Production and Their Impacts on Farm and Economic Performance

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT This paper investigates the effects of two greenhouse gas (GHG) mitigation practices—minimum tillage and mid‐season drainage—on rice farmers' farm performance (e.g., crop yield and risk) and economic outcomes (e.g., income and vulnerability).

Atmospheric Evolution

, 2017
Earth's atmosphere has evolved as volatile species cycle between the atmosphere, ocean, biomass and the solid Earth. The geochemical, biological and astrophysical processes that control atmospheric evolution are reviewed from an "Earth Systems ...

A genomic view of methane oxidation by aerobic bacteria and anaerobic archaea.

Genome biology, 2005
Recent sequencing of the genome and proteomic analysis of a model aerobic methanotrophic bacterium, Methylococcus capsulatus (Bath) has revealed a highly versatile metabolic potential. In parallel, environmental genomics has provided glimpses into anaerobic methane oxidation by certain archaea, further supporting the hypothesis of reverse ...

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...

Waterfalls enhance regional methane emissions by enabling dissolved methane to bypass microbial oxidation

Communications Earth & Environment
River waters are significant sources of atmospheric methane whose local emissions increase with river slope and turbulence. However, when integrated regionally, the amount of dissolved methane released to the atmosphere is uninfluenced by local changes ...

Study on Oxidation Rate and Isotope Fractionation of Methane in Bohai Sea Sediments

Yankuang ceshi, 2018
BACKGROUND:The Bohai Sea contains a large amount of oil and gas, the main component of which is methane. The influence of natural or human factors will cause its leakage and migration and then have a negative impact on the environment.
