Wet Season Carbon (δ13C) and Nitrogen (δ15N) Composition of Modern Plants as Isotopic Framework for Agropastoral and Palaeoecological Studies in Northern Greece

open access: yesArchaeometry, EarlyView.
ABSTRACT Mediterranean wetlands are one of Europe's most vital and endangered biodiversity hotspots. This study determined the carbon (δ13C) and nitrogen (δ15N) isotope values of modern plants to construct an isotopic framework by which to contextualize agropastoral management in and around past wetland ecosystems.

Single‐dose Pasteurella multocida and Histophilus somni autogenous vaccines administered at induction significantly improved feedlot cattle performance and profitability in Australia

open access: yesAustralian Veterinary Journal, EarlyView.
Background Bovine respiratory disease (BRD) is the most economically important disease affecting feedlot cattle. While viral pathogens are initiating agents, bacterial coinfections exacerbate disease severity. Vaccines for Pasteurella multocida and Histophilus somni are not commercially available in Australia.

From rhetoric to measurement: The economics of wetland conservation

open access: yesCanadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract Wetland conservation continues to be a pressing issue as wetlands continue to be lost due to urban, industrial, and agricultural expansion. This paper synthesizes the current knowledge about wetland conservation economics in Canada, with a focus on prairie landscapes. We review the methods economists use to empirically measure the costs (i.e.,
