The complex interaction between mammalian herbivores, climate, soil and fire has shaped the evolution and distribution of plant spinescence across biogeographical realms

New Phytologist, EarlyView.
Evolution of spinescence in mimosoid legumes. Summary The evolutionary arms race between plants and herbivores led to numerous plant adaptations, including spinescence. However, the balance between herbivory and abiotic conditions in the evolution of spinescence remains unclear. We integrated phylogenetic, geographic, and trait data for 2686 species of

Periodontology 2000, EarlyView.
Abstract Uneven gingival margins may cause visible asymmetries during smiling and may reflect alterations in the tooth shape and morphology, particularly in cases requiring restorative procedures. Despite being perceived as a minor health condition, presence of uneven gingival margins usually impacts the smile aesthetics and could affect the individual'

Little Fish in Big Ponds: The Pathways to Inclusion for Micro‐Minorities in Power‐Sharing Societies

Swiss Political Science Review, EarlyView.
Abstract Emergent critique of consociations has focused on how micro‐minority ‘others’ are frequently excluded from the opportunities presented by power‐sharing systems, with dominant elites shutting them out. Therefore, a key question is: how do the political elites of micro‐minorities gain more meaningful inclusion by adopting or navigating the ...
