Size, not phylogeny, explains the morphology of the endosseous labyrinth in the crown clade Crocodylia

Journal of Anatomy, Volume 246, Issue 4, Page 558-574, April 2025.
Here, we present the most complete dataset to date on the endosseous labyrinths of extant crocodylians. Using 3D geometric morphometrics, we show that allometry constitutes a major contributor of the shape variation of the crocodylian endosseous labyrinths and that the development of this structure is likely linked to the braincase conformation, in all

When Infrastructure Pushes Residents Out: High‐Speed Rail and Tourism Outflows

Journal of Regional Science, EarlyView.
ABSTRACT This paper examines the impact of high‐speed rail (HSR) connectivity on both inbound and outbound tourism inflows. Leveraging the opening of a new HSR line connecting a northern Spanish region with mainland Spain, we employ a triple difference‐in‐differences design combined with inverse probability weighting (IPW) to evaluate the causal effect
