Species‐specific habitat preferences do not shape the structure of a crested newt hybrid zone (Triturus cristatus x T. carnifex)

open access: yesEcology and Evolution, 2019
Reproductive isolation barriers maintain the integrity of species by preventing interspecific gene flow. They involve temporal, habitat or behavioral isolation acting before fertilization, and postzygotic isolation manifested as hybrid mortality or ...

Potential allopolyploid origin of Ericales revealed with gene-tree reconciliation

open access: yesFrontiers in Plant Science, 2022
Few incidents of ancient allopolyploidization (polyploidization by hybridization or merging diverged genomes) were previously revealed, although there is significant evidence for the accumulation of whole genome duplications (WGD) in plants.

The origin of human chromosome 2 analyzed by comparative chromosome mapping with a DNA microlibrary [PDF]

open access: yes, 1994
Fluorescencein situ hybridization (FISH) of microlibraries established from distinct chromosome subregions can test the evolutionary conservation of chromosome bands as well as chromosomal rearrangements that occurred during primate evolution and will ...

Hybridations et effacement du chanteur : l’emploi des codes de la lyric video dans le clip de « Where are we now? »

open access: yesMiranda: Revue Pluridisciplinaire du Monde Anglophone, 2018
“Where are we now?” was the question David Bowie asked in a music video directed by American plastician Tony Oursler, and released in 2013. Over the years, Bowie created many avatars, notably thanks to music videos, and in 2016, he would even ...

Genotype‐by‐environment interactions drive the maintenance of genetic variation in a Salmo trutta L. hybrid zone

open access: yesEvolutionary Applications, 2021
Allopatric gene pools can evolve in different directions through adaptive and nonadaptive processes and are therefore a source of intraspecific diversity.

In vitro identification and in silico utilization of interspecies sequence similarities using GeneChip(® )technology [PDF]

open access: yes, 2005
BACKGROUND: Genomic approaches in large animal models (canine, ovine etc) are challenging due to insufficient genomic information for these species and the lack of availability of corresponding microarray platforms. To address this problem, we speculated

Morphological variability of Helleborines. I. Diagnostic significance of morphological features in Epipactis helleborine (L.) Crantz, Epipactis atrorubens (Hoffm.) Besser and their hybrid, Epipactis ×schmalhausenii Richt. (Orchidaceae, Neottieae)

open access: yesActa Societatis Botanicorum Poloniae, 2011
The comparative analysis of leaf morphology was performed in E. helleborine (L.) Crantz, E.atrorubens (Hoffm.) Besser, and their interspecific hybrid, Epipactis ×schmalhausenii Richt. The aim of this research was to find out features that would be useful
