Climate and hybridization shape stomatal trait evolution in Populus
New Phytologist, Volume 249, Issue 2, Page 792-809, January 2026.Summary Stomata play a critical role in regulating plant responses to climate. Where sister species differ in stomatal traits, interspecific gene flow can influence the evolutionary trajectory of trait variation, with consequences for adaptation. Leveraging six latitudinally distributed contact zones spanning the natural hybrid zone between Populus ...

Reduced Offspring Viability Is Associated With Long‐Term Stability of a Narrow Avian Hybrid Zone
Ecology and Evolution, Volume 15, Issue 9, September 2025.We investigated hybrid viability in a tropical, avian hybrid zone governed by strong selection on male secondary sexual traits between the white‐collared manakin (Manacus candei) and golden‐collared manakin (M. vitellinus). We assessed putative hybrid fitness by investigating adult survival and hatching success along with a prospective selective ...

The voyage of the Serliana motif, a journey to understand the transmission of architectural values through space and time [PDF]
, 2019 Following the idea of a drastic reduction of linguistic tools in the early Renaissance we have to assume a recovery of the Serliana motif only in the 16th century, after its practical disappearance for several centuries.

Understanding Chiral Proton Catalysis Using Cinchonium Derivatives in aza‐Michael Additions
Advanced Synthesis &Catalysis, Volume 367, Issue 11, June 3, 2025.Abstract This work presents a detailed mechanistic study of a quininium‐catalyzed aza‐Michael reaction, providing essential information for advancing chiral proton catalysis (CPC). The use of cinchona derivatives as chiral proton catalysts demonstrates their potential beyond their conventional roles as base‐promoted and phase‐transfer catalysts ...
