Apatite in Carbonatite Preserving Primary Magmatic, Post‐Magmatic Overgrowth, and Post India‐Asia Collision‐Related Hydrothermal Alteration: Evidenced From U–Pb Isotope and Trace Element Geochemistry

open access: yesGeological Journal, EarlyView.
U–Pb isotope and trace element geochemistry of apatite from carbonatites of Peshawar Plain Alkaline Igneous Province, western Himalaya shows Permo‐Carboniferous magmatism, an additional magmatic pulse during Cretaceous, and post‐magmatic hydrothermal/metasomatism during Oligocene. ABSTRACT U–Pb isotope and trace element geochemistry of apatite combined

Miocene to Quaternary Tectonostratigraphic Evolution of the Northern Section of the Burdur‐Fethiye Shear Zone, South‐Western Türkiye

open access: yesGeological Journal, EarlyView.
New zircon ages reveal that lacustrine sedimentation initiated in the Late Miocene (Messinian), revising earlier Pliocene age assignments. The study results support the interpretation of the northern BFSZ as a broad left‐lateral transtensional shear zone rather than a discrete sinistral fault or simple extensional graben array.

Spatial Patterns of Seed Plants and Their Conservation Priorities in Jiangxi Province, China 中国江西省种子植物的空间格局及其保护优先区

open access: yesIntegrative Conservation, EarlyView.
We comprehensively evaluated the seed plant diversity of Jiangxi province to address the regional biodiversity conservation of Asian subtropical evergreen broad‐leaved forests (EBLFs). Higher species diversity of seed plants was observed in eastern, southern, and western Jiangxi, with elevation and precipitation as mainly environmental factors.

Calappa praelata Lőrenthey in Lőrenthey & Beurlen, 1929 (Decapoda, Brachyura, Calappidae) from the Middle Miocene of Tresnuraghes (Oristano, Sardegna, Italy)

open access: yesNatural History Sciences, 2012
We report Calappa praelata Lőrenthey in Lőrenthey & Beurlen, 1929 (Calappidae De Haan, 1833), based upon one single carapace, three-dimensionally preserved, from the Middle Miocene of Tresnuraghes (Oristano, Sardegna, Italy).

Barbacenia pendula sp. nov.(Velloziaceae) from the northern Espinhaço Range of Minas Gerais, Brazil

open access: yesNordic Journal of Botany, EarlyView.
Although botanical exploration in the Espinhaço Range has increased in recent years, several areas remain poorly sampled, particularly in northern Minas Gerais. Recently, this area has been receiving scientific expeditions, leading to the description of several new plant species.

Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Seismic-based structural framework and sequence stratigraphy of the Bakr–Amer–Al Hamd fields, central Gulf of Suez, Egypt: implications for hydrocarbon exploration

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
The Miocene succession of the Bakr–Amer–Al Hamd fields, central Gulf of Suez, Egypt, is interpreted using seismic integration and well logs to delineate its structural and sequence stratigraphic framework.

Waves of range dynamics and gene flow characterize the biogeographic history of Litsea elongata, a dominant tree in East Asian evergreen broadleaved forests

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Evergreen broadleaved forests (EBLFs) represent an iconic vegetation type in subtropical montane East Asia, but they are experiencing intensifying anthropogenic pressure and increasing habitat fragmentation. Here, using a dominant and widespread tree species characteristic of East Asian EBLFs, we examine its phylogeographic history and evaluate what it

Conservation gap analysis for wild grapevines (Vitis L.) of the Americas

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Wild grapevines (Vitis L.) native to the Americas are ecologically and culturally important plants that are also critical to the global cultivated grape industry as sources of traits for crop innovation, but many of these species are poorly documented and insufficiently conserved.
