Systematic Entomology, EarlyView.Genomic data refine the species boundary of Papilio machaon and confirm the species status of Papilio saharae, with clarification of subspecies delineation of Mediterranean machaon and saharae. A heterogeneous level of genome‐wide heterozygosity between island and continental lineages warrants further taxonomic implications, and there is also evidence ...

Terra Nova, EarlyView.ABSTRACT The long‐term evolution of orogenic drainage systems is closely related to the propagation of tectonic structures, which gives rise to the topography and hence anisotropies for river incision. This study focuses on the subalpine Vercors Massif (SW French Alps), reconstructing the geometry of an uplifted paleo‐canyon and applying calcite U–Pb ...

Hydrous Asthenosphere Underneath the Northern Pannonian Basin
Terra Nova, EarlyView.ABSTRACT This study reveals the structural hydroxyl content in clinopyroxenes of three cumulate xenoliths from the Nógrád‐Gömör/Novohrad‐Gemer Volcanic Field (northern Pannonian Basin), with values ranging from 275 to 384 ppm. Based on these data, the water content of the equilibrium parental alkali basaltic melt was estimated to be between 1.5 and 2.1

The Chamrousse Ophiolite (Western Alps, France): Relict of a Devono‐Carboniferous Ocean
Terra Nova, EarlyView.ABSTRACT The Chamrousse ophiolite (Western Alps, France) is one of the best‐preserved Variscan relicts of Cambro‐Ordovician oceanisation within the northern Gondwana margin. This study presents new in situ U–Pb isotope analyses on zircon grains from that ophiolite, revealing that the oceanic stage in Chamrousse has occurred 150 Ma later than estimated.

Schist Belts of the Benin‐Nigeria Shield Reveal a Neoproterozoic History
Terra Nova, EarlyView.ABSTRACT Belts of metasedimentary rocks (schist belts) in the Benin‐Nigeria Shield (BNS) are investigated for the first time using U–Pb dating and Lu‐Hf isotope analysis of detrital zircons. We report maximum depositional ages that place their deposition firmly in the Neoproterozoic and link them with strata in the Dahomey Belt, the central African ...
