Greenhouse Gas Emission Factor Module: Land Use in Rural New Zealand—Climate Version 1 [PDF]

Several different New Zealand economic models produce measures of rural economic activity that have greenhouse gas implications. For climate change analysis, models need to translate economic activity into greenhouse gas emissions.

Estimating the Marginal Costs of Greenhouse Gas Emissions Abatement using Irish Farm-Level Data [PDF]

Agriculture in Ireland accounts for a higher proportion of greenhouse gas (GHG) emissions than in any other EU member state. Furthermore as part of the EU’s commitment to reduce emissions by 20 percent by 2020, Ireland is one of the few countries who ...

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

Low Greenhouse Gas Agriculture: Mitigation and Adaptation Potential of Sustainable Farming Systems [PDF]

, 2009
Is low greenhouse gas emission (GHG) agriculture possible? Is it, in fact, desirable? In seeking answers to these two basic but extremely relevant questions, this study examines current farming practices, and incorporates scientific databases from ...

Resistome flow in global landfill systems

iMetaOmics, EarlyView.
Global landfill systems represent key hubs of resistome, serving as dynamic reservoirs and amplifiers through plasmid‐driven gene mobility. Waste flows and environmental pathways sustain the transboundary resistome networks, accelerating resistance dissemination across ecosystems.

The role of the gut microbiome in the regulation of high‐altitude adaptation

iMeta, EarlyView.
This study is the first to elucidate mechanisms of high‐altitude adaptation from the perspective of the rumen ecosystem by using indigenous yaks and Holstein cows that have lived at high altitude since birth as comparative models. Through a systematic comparison of their rumen ecology using multi‐omics approaches—including rumen metagenomics ...

Probing Metal Tip‐Induced Bond Weakening of a Reactive Alkyne Center Aligned via a Rigid Triphenylmethane‐Based Tripod on Au(111) by TERS and DFT

Journal of Raman Spectroscopy, EarlyView.
We investigate tip‐induced bond weakening of a single alkyne center immobilized and aligned upright on Au(111) using a rigid triphenylmethane‐based tripod. By varying the tip–molecule distance, we observe shifts in the ≡C–H and –C≡C– vibrational bands via ultrahigh vacuum low‐temperature tip‐enhanced Raman scattering (TERS).

A Review of Producer Adoption in the U.S. Beef Industry with Application to Enteric Methane Emission Mitigation Strategies

Animals
Cattle are ruminant animals that produce enteric methane (CH4) emissions as a byproduct of their natural digestive process. U.S. beef producers have been receiving pressure to reduce production emissions.
