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 ...
Ongoing speciation within the Anastrepha fraterculus cryptic species complex: the case of the Andean morphotype
(Wiley Blackwell Publishing, Inc, 2014-06)
The Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) cryptic species complex is currently composed of seven taxonomically recognized morphotypes. Both, pre- and post-zygotic isolation has been documented among ...
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 ...
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 ...
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 ...
Hybridization in Phlebotominae (Diptera: Psychodidae): A mini-review
(2020-12-01)
Taxonomy based only on morphology, although extremely important for the classification of sandflies, has been shown to be insufficient for the delimitation of some taxa. Thus, integrative taxonomy could play a fundamental ...
Ongoing speciation within the Anastrepha fraterculus cryptic species complex: the case of the Andean morphotype
(Wiley, 2014-09)
The Anastrepha fraterculus (Wiedemann) (Diptera: Tephritidae) cryptic species complex is currently composed of seven taxonomically recognized morphotypes. Both, pre‐ and post‐zygotic isolation has been documented among ...
Trends in evolution of the Rhodniini tribe (Hemiptera, Triatominae): experimental crosses between Psammolestes tertius Lent & Jurberg, 1965 and P. coreodes Bergroth, 1911 and analysis of the reproductive isolating mechanisms
(2021-12-01)
Background: The tribe Rhodniini is a monophyletic group composed of 24 species grouped into two genera: Rhodnius and Psammolestes. The genus Psammolestes includes only three species, namely P. coreodes, P. tertius and P. ...
Pollinators and crossability as reproductive isolation barriers in two sympatric oil rewarding Calceolaria (Calceolariaceae) species
(Springer, 2017)
Pollinator species are widely accepted as an important factor in plant reproductive
isolation. Although mostly investigated in plants visited by different groups of
pollinators (e.g., hummingbirds vs bees), few studies ...
