Transitions between self-compatibility and self-incompatibility and the evolution of reproductive isolation in the large and diverse tropical genus Dendrobium (Orchidaceae)
(Oxford Univ Press, 2015-09-01)
Methods The role of SC and SI changes in reproductive compatibility among species was examined using fruit set and seed viability data available in the literature from 86 species and 2500 hand pollinations. The evolution ...
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 ...
Multiple sources of reproductive isolation in a bimodal butterfly hybrid zone
An important evolutionary question concerns whether one or many barriers are involved in the early stages of speciation. We examine pre? and post?zygotic reproductive barriers between two species of butterflies (Heliconius ...
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 ...
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 ...
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 ...
Conditions for neutral speciation via isolation by distance
(Academic Press Ltd- Elsevier Science LtdLondonInglaterra, 2013)
Divergence and evolution of reproductive barriers among three allopatric populations of Rhagoletis cingulata across eastern North America and México
(Wiley, 2015-09)
Geography is often a key factor facilitating population divergence and speciation. In this regard, the geographic distributions of flies in the genus Rhagoletis (Diptera: Tephritidae) in temperate North America have been ...
Independent fusions and recent origins of sex chromosomes in the evolution and diversification of glass knife fishes (Eigenmannia)
(NATURE PUBLISHING GROUP, 2011)
The genus Eigenmannia comprises several species groups that display a surprising variety of diploid chromosome numbers and sex-determining systems. In this study, hypotheses regarding phylogenetic relationships and karyotype ...
