Growth of Omnichannel Grocery Retailing and Food Prices

Agribusiness, EarlyView.
ABSTRACT This paper examines the effects of the growth of omnichannel grocery retailing on food prices. We first develop a conceptual model of consumer choice and retailer pricing that allows us to evaluate changes in equilibrium prices, quantities, and profits with online channel growth and alternative pricing strategies.

The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry

Agribusiness, EarlyView.
ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

American Journal of Botany, EarlyView.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Ocular and Systemic Findings in COL2A1 and COL11A1 Stickler Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Stickler syndrome is most commonly caused by variants in COL2A1 and COL11A1 genes. The purpose of this study was to describe genetic variants and phenotypes in COL2A1 and COL11A1 Stickler syndrome. We performed a retrospective genotype–phenotype evaluation of COL2A1 and COL11A1 Stickler syndrome subjects. Thirty‐two subjects with COL2A1 and 13
