Nordic Journal of Botany, EarlyView.The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Aster tongrenensis (Asteraceae), a remarkable new species from Guizhou, China
Nordic Journal of Botany, EarlyView.Aster tongrenensis (Asteraceae), a remarkable new species from Guizhou, China, is here described, illustrated and compared with related taxa based on integrated evidence from morphology, micromorphology and molecular phylogeny. Morphological and micromorphological observations indicate that A. tongrenensis is most similar to A.

International Journal of Osteoarchaeology, EarlyView.ABSTRACT Lions (Panthera leo) are apex predators with a well‐documented influence on ecological dynamics, yet their potential role as bone‐accumulating agents remains poorly understood and often debated. Previous taphonomic studies have largely attributed bone accumulations in African savannah ecosystems to other carnivores, such as spotted hyenas ...

Impact of Al3+ Concentration on Montmorillonite Sedimentation: Insights Into Particle Size Behavior
ChemistryOpen, EarlyView.The current research essentially focuses on the coagulation and sedimentation characteristics of particles with two distinct particle‐size compositions. The DLVO theory confirms that under the influence of aluminum ions, the coarse and fine particle sampleS of montmorillonite essentially possess the effect of eliminating or weakening the “barrier ...

Rare Metals, EarlyView.ABSTRACT Introducing solid‐state phase transformations into the design of heterogeneous structures is considered an effective strategy for simultaneously optimizing both microstructure and mechanical properties. This study investigates the thermodynamic and kinetic mechanisms of the γ → α transformation in Ti48Al5Nb2Cr0.6Re0.1C alloy under different ...
