Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins

Remote Sensing in Ecology and Conservation, EarlyView.
Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.

Extreme Weather Events and Agricultural Total Factor Productivity Growth

Southern Economic Journal, EarlyView.
ABSTRACT The productivity of the agricultural sector is crucial for food security in a changing climate. This study estimates the impacts of extreme weather events on agricultural total factor productivity (TFP) growth, contributing to a more comprehensive understanding of the effects of climate change on agriculture.

Robust Synthesis of Prebiotic Precursors in Drying Reactions of Amino Acids and Keto Acids

ChemSystemsChem, EarlyView.
Drying conditions drive reactions between amino acids and keto acids, generating a wide variety of small, reactive species, highlighting for the first time the potential significance of drying reactions in proto‐metabolism on early Earth. Condensation‐dehydration reactions are critical to both metabolism and polymerization in extant biology, and their ...

FaXToR: the hard X‐ray micro‐tomography beamline at the Spanish synchrotron ALBA

Journal of Synchrotron Radiation, EarlyView.
The Spanish synchrotron ALBA has recently inaugurated BL31‐FaXToR, a beamline for hard X‐ray micro‐tomography. The design, performance and scientific program of the beamline are described.FaXToR is the first hard X‐ray imaging beamline built and commissioned at the Spanish synchrotron light source ALBA, and therefore the start of user operation marks ...
