Abstract Estimates suggest that about 16% of bird species hybridize in the wild. This number is based on two main sources: Handbook Avian Hybrids World by Eugene McCarthy and online Serge Dumont Bird Database. Although both sources provide supporting references for documented hybrids, reliability these has not been systematically assessed. In this paper, I introduce a scoring scheme three crite...

Distinguishing between hybrid introgression and incomplete lineage sorting causing incongruence among gene trees in that they exhibit topological differences requires application of statistical approaches that are based on biologically relevant models. Such study is especially challenging in hybrid systems, where usual vectors mediating interspecific gene transfers--hybrids with Mendelian hered...

Abstract Plants respond to drought stress through different physiological mechanisms. To highlight a specific adaptation strategy related stem photosynthetic activity, woody tissue pigmentation was studied. In this work, 25 Vitis hybrids were studied in two experimental vineyards: one of them with sufficient water availability and the other showing stress. 1500 reflectance spectra tissues colle...

To investigate the response of poplar hybrids to drought, leaves were collected from plants to which water was suspended for 8 and 13 days. After measuring the respective relative water content, RNAs were isolated from leaves of moderately and severely droughted plants and from control plants, and Illumina RNA sequencing was performed to analyze RNA synthesis in these tissues. Our data provide ...
