Three‐Dimensional Numerical Simulations of Internal Tides in the Cape Verde and Senegalo‐Mauritanian Upwelling Regions

open access: yesJournal of Geophysical Research: Oceans, Volume 130, Issue 11, November 2025.
Abstract Tide‐topography interactions, key drivers of upwelling and mixing, remain poorly understood within the Cape Verde area (CVA) and the Senegalo‐Mauritanian upwelling regions. Therefore, a three‐dimensional numerical model, initialized with horizontally uniform stratification and driven by barotropic tidal forcing only, is employed to study the ...

Leaf anatomy of species of Calea sect. Lemmatium (Asteraceae) with a taxonomic emphasis

open access: yesNordic Journal of Botany, Volume 2025, Issue 10, October 2025.
Calea sect. Lemmatium is one of five sections of Calea (Neurolaeneae, Asteraceae), containing 12 species that are morphologically similar, which makes their identification difficult to non‐experts. The current study aimed to provide an anatomical characterization of species from Calea sect.
