Policy uncertainty shocks and farm investments in Europe: Evidence from a newspaper‐based index

open access: yesAmerican Journal of Agricultural Economics, EarlyView.
Abstract In order to quantify the impact of agricultural policy uncertainty on European farmers' investment behavior, we construct a newspaper‐based monthly index of European agricultural policy uncertainty from 2013 to 2023. We use 327,224 newspaper articles to assess and compare the trends in policy uncertainty across five top agricultural producers ...

Success of coastal sage scrub restoration is influenced by local adaptations of shrub species

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Restoring plant communities is increasingly challenging with climate change. While practitioners have traditionally used local seed sources, many are recommending assisted migration, possibly from more extreme environments such as inland rather than coastal environments, for restoration.

CO‐Adsorption on MgO Revisited: Polarization‐Resolved Identification of Step Edges as the Dominant Defects on MgO(100) and MgO(110)

open access: yesAngewandte Chemie International Edition, EarlyView.
By combining polarization‐resolved IRRAS with hybrid HSE06 DFT calculations, we establish site‐specific vibrational fingerprints, adsorption geometries, and binding energies for CO on wide‐band‐gap MgO surfaces. Low‐coordinated Mg4c2+ step‐edge sites, rather than terrace Schottky defects, are identified as the dominant binding and reactive sites, with ...

Spin Transport in Thin Copper Channels Fabricated via Thermal Scanning Probe Lithography

open access: yesAdvanced Physics Research, EarlyView.
Thermal scanning probe lithography (t‐SPL) is demonstrated as an alternative to electron‐beam lithography for fabricating all‐metallic non‐local spin valves with ∼100 nm features. Devices exhibit strong spin signals and clean magnetic switching, demonstrating the viability of t‐SPL for nanoscale spintronics.

Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation

open access: yesThe Anatomical Record, EarlyView.
Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.

Bioerosion traces in bones reveal an increase in ethological diversity in the insect exploitation of carcasses in the late Triassic

open access: yesThe Anatomical Record, EarlyView.
Abstract This study presents the first detailed description of bioerosion traces produced by insects in bones from the Santa Cruz Sequence (early Carnian, Santa Maria Supersequence, Brazil). An array of traces is reported, consisting of notches, a tube, trails of grooves attributed to the ichnotaxon Osteocallis mandibulus and ornamented depressions ...
