Molecular and classical cytogenetic analyses demonstrate an apomorphic reciprocal chromosomal translocation in Gorilla gorilla [PDF]

open access: yes, 1992
The existence of an apomorphic reciprocal chromosomal translocation in the gorilla lineage has been asserted or denied by various cytogeneticists. We employed a new molecular cytogenetic strategy (chromosomal in situ suppression hybridization) combined ...

Parsimonious Inference of Hybridization in the Presence of Incomplete Lineage Sorting [PDF]

open access: yesSystematic Biology, 2013
Hybridization plays an important evolutionary role in several groups of organisms. A phylogenetic approach to detect hybridization entails sequencing multiple loci across the genomes of a group of species of interest, reconstructing their gene trees, and taking their differences as indicators of hybridization. However, methods that follow this approach

Hybrids of amphibian chytrid show high virulence in native hosts

open access: yesScientific Reports, 2018
Hybridization of parasites can generate new genotypes with high virulence. The fungal amphibian parasite Batrachochytrium dendrobatidis (Bd) hybridizes in Brazil’s Atlantic Forest, a biodiversity hotspot where amphibian declines have been linked to Bd ...

Genetic identification, morphology and distribution of Natrix helvetica subspecies in southern and western Switzerland (Reptilia, Squamata, Serpentes) [PDF]

open access: yesZooKeys
Most of Switzerland is inhabited by the nominotypical subspecies of the barred grass snake (Natrix helvetica helvetica), which is characterized by mitochondrial DNA lineage E. Only in the northeast of the country, the common grass snake (N.

Hominin evolution was caused by introgression from Gorilla

open access: yes, 2018
The discovery of Paranthropus deyiremeda in 3.3-3.5 million year old fossil sites in Afar, together with 30% of the gorilla genome showing lineage sorting between humans and chimpanzees, and a NUMT ("nuclear mitochondrial DNA segment") on chromosome 5 ...

Hybrid cells differentiate to hepatic lineage cells and repair oxidative damage [PDF]

open access: yesCellular and Molecular Biology Letters, 2010
AbstractHybrid cells derived from stem cells play an important role in organogenesis, tissue regeneration and cancer formation. However, the fate of hybrid cells and their range of function are poorly understood. Fusing stem cells and somatic cells induces somatic cell reprogramming, and the resulting hybrid cells are embryonic stem cell-like cells ...

Establishment of a hybrid lineage via Megalobrama amblycephala (♀) × Culter alburnus (♂) and Genetic Analysis

open access: yesAquaculture Reports
Distant hybridization is a significant method for creating new hybrid lineages and potentially hybrid species. In the past ten years, we have established a hybrid lineage population, BTF1-BTF6 (six generations), via crosses between Megalobrama ...

Sequence-Based Analysis of Thermal Adaptation and Protein Energy Landscapes in an Invasive Blue Mussel (Mytilus galloprovincialis). [PDF]

open access: yes, 2017
Adaptive responses to thermal stress in poikilotherms plays an important role in determining competitive ability and species distributions. Amino acid substitutions that affect protein stability and modify the thermal optima of orthologous proteins may ...

HYBRID SPECIATION AND INDEPENDENT EVOLUTION IN LINEAGES OF ALPINE BUTTERFLIES [PDF]

open access: yesEvolution, 2013
The power of hybridization between species to generate variation and fuel adaptation is poorly understood despite long-standing interest. There is, however, increasing evidence that hybridization often generates biodiversity, including via hybrid speciation.

Unveiling current Guanaco distribution in chile based upon niche structure of phylogeographic lineages: Andean puna to subpolar forests. [PDF]

open access: yesPLoS ONE, 2013
Niche description and differentiation at broad geographic scales have been recent major topics in ecology and evolution. Describing the environmental niche structure of sister taxa with known evolutionary trajectories stands out as a useful exercise in ...
