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

Recent, independent and anthropogenic origins of Trypanosoma cruzi hybrids. [PDF]
PLoS Neglected Tropical Diseases, 2011 The single celled eukaryote Trypanosoma cruzi, a parasite transmitted by numerous species of triatomine bug in the Americas, causes Chagas disease in humans. T.

Hybridization and gene flow in the mega-pest lineage of moth, Helicoverpa [PDF]
Proceedings of the National Academy of Sciences, 2018 Significance Helicoverpa armigera is a major agricultural and horticultural pest that recently spread from its historical distribution throughout much of the Old World to the Americas, where it is already causing hundreds of millions of dollars in damage every year.

, 2022 The vast diversity of species we encounter in nature has always fascinated scientists, thus the evolutionary processes responsible for the origin of new species (speciation) is a topic of constant interest among biologists. One special form of speciation

PLoS ONE, 2013 The complex process of allopolyploid speciation includes various mechanisms ranging from species crosses and hybrid genome doubling to genome alterations and the establishment of new allopolyploids as persisting natural entities.

Evidence of Natural Hybridization in Brazilian Wild Lineages ofSaccharomyces cerevisiae [PDF]
Genome Biology and Evolution, 2016 The natural biology of Saccharomyces cerevisiae, the best known unicellular model eukaryote, remains poorly documented and understood although recent progress has started to change this situation. Studies carried out recently in the Northern Hemisphere revealed the existence of wild populations associated with oak trees in North America, Asia, and in ...

Early stages of sympatric homoploid hybrid speciation in crater lake cichlid fishes. [PDF]
, 2022 Homoploid hybrid speciation (i.e., hybrid speciation without a change in ploidy) has traditionally been considered to be rare in animals. Only few accepted empirical examples of homoploid hybrid speciation in nature exist, and in only one previous case ...

BiologyDistant hybridization is key to trait innovation and speciation, with Cyprinidae hybrid phylogeny helping to clarify diversification mechanisms. Yet, a major gap persists in Cyprinidae studies: the stabilization mechanisms of interspecific distant hybrid

Hybrids of amphibian chytrid show high virulence in native hosts
Scientific 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 ...

Assessment of Prunus Rootstock Accessions Using Chloroplast and Nuclear Microsatellites
Journal of the American Society for Horticultural Science, 2022 A rootstock collection of Prunus species and hybrids is maintained at the U.S. Department of Agriculture stone fruit breeding program at Byron, GA. We genotyped 66 Prunus rootstock accessions and clones using chloroplast and nuclear microsatellites in ...
