Evolution of pre‐zygotic and post‐zygotic barriers to gene flow among three cryptic species within the Anastrepha fraterculus complex
(Wiley, 2013-09)
Tropical tephritids are ideally suited for studies on population divergence and speciation because they include species groups undergoing rapid radiation, in which morphologically cryptic species and sister species are ...
Evolution of pre-zygotic and post-zygotic barriers to gene flow among three cryptic species within the Anastrepha fraterculus complex
(Wiley, 2013-06)
Tropical tephritids are ideally suited for studies on population divergence and speciation because they include species groups undergoing rapid radiation, in which morphologically cryptic species and sister species are ...
Incipient speciation revealed in Anastrepha fraterculus (Diptera; Tephritidae) by studies on mating compatibility, sex pheromones, hybridization, and cytology
(Wiley Blackwell Publishing, Inc, 2009-05)
It has long been proposed that the nominal species Anastrepha fraterculus is a species complex and earlier studies showed high levels of pre-zygotic isolation between two laboratory strains from Argentina and Peru. Further ...
Chromosomal polymorphism and speciation: The case of the genus mazama (cetartiodactyla; cervidae)
(2021-02-01)
Chromosomal polymorphism plays a major role in speciation processes in mammals with high rates of karyotypic evolution, as observed in the family Cervidae. One remarkable example is the genus Mazama that comprises wide ...
Genetic differentiation among distinct karyomorphs of the wolf fish Hoplias malabaricus species complex (Characiformes, Erythrinidae) and report of unusual hybridization with natural triploidy
(Wiley-Blackwell, 2014-11-01)
In this study, genetic differentiation between karyomorphs A (2n=42) and D (2n=39/40) of the wolf fish Hoplias malabaricus, which is comprised of several cryptic species that present a wide variety of diploid chromosome ...
Self-compatible sympatric Chamaecrista (Leguminosae- Caesalpinioideae) species present different interspecific isolation mechanisms depending on their phylogenetic proximity
(Plant Systematics and Evolution, 2013)
The mating system of seven sympatric taxa of
Chamaecrista occurring in the Chapada Diamantina
Mountains, northeastern Brazil, was studied to determine
the occurrence of self-incompatibility and interspecific
genetic ...
Expression of internal reproductive barriers in a germplasm bank accession of the wild potato Solanum chacoense Bitter in three ex situ regeneration cycles
(Springer, 2021-03)
Wild potatoes (Solanum sp.) are important reservoirs of desirable genes for potato breeding. Most of them are diploid and obligate outcrossers, with both sexual and asexual reproduction. Samples of natural populations are ...
