Reduced Offspring Viability Is Associated With Long-Term Stability of a Narrow Avian Hybrid Zone. [PDF]
Ecol EvolWe 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 ...

Climate and hybridization shape stomatal trait evolution in Populus. [PDF]
New PhytolSummary 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 ...

Synthesis and characterization of the polyaniline dopant Schiff base
Orbital: The Electronic Journal of Chemistry, 2012 The Schiff base, N-salicilidenoanilina was used as dopant to induce polymerization of aniline and thus preparing polyaniline (PAni). The different conditions of preparation, including Schiff base structure, and the dosage of acidity reaction medium, were
