Making vertebrate fossil radiocarbon dates more useful for global scientific research
ABSTRACT Radiocarbon dating of bones is essential for reconstructing timelines of species' occurrences, domestication, extinction, migrations, and interactions with Quaternary environments. Many studies compile these chronologies at continental to global scales by aggregating radiocarbon dates from various sources, often balancing data quantity and ...

Abstract BACKGROUND Livestock production contributes largely to climate change and methane (CH4) from enteric fermentation is the primary greenhouse gas emitted from ruminants. Thus, developing effective strategies to reduce the impact of ruminant production on the environment is crucial, and the combination of CH4 mitigating agents may be a viable ...

Abstract BACKGROUND Global food insecurity and the fact that food production contributes around 30% of greenhouse gas (GHG) emissions is a major planetary challenge. Ruminant products are widely consumed since they are macro‐ and micronutrient dense; however, ruminants produce enteric methane (CH4), a potent GHG.

We incorporated landscape suitability into a trumpeter swan range expansion model. We estimated a 4.4% (95% CI: 2.0–6.9%) annual range expansion rate from 2023 to 2033, with expansion occurring in the Prairie Pothole Region of the Dakotas and the Boreal Shield and James Bay Lowlands of Canada. Abstract The Interior Population of trumpeter swans (Cygnus
