Variation in reproductive systems facilitates species boundaries of sympatric Vriesea (Bromeliaceae)
(2017-06-01)
Divergence in reproductive systems among plant species often involves changes in floral traits. The distance separating stigmas and anthers (herkogamy) directly affects the relative importance of reproduction by outcrossing ...
Strong but permeable barriers to gene exchange between sister species of Epidendrum
(Botanical Soc Amer Inc, 2016-08-01)
PREMISE OF THE STUDY: The investigation of reproductive barriers between sister species can provide insights into how new lineages arise, and how species integrity is maintained in the face of interspecific gene flow. ...
Strong But Permeable Barriers To Gene Exchange Between Sister Species Of Epidendrum
(Botanical Soc Amer IncSt Louis, 2016)
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 ...
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 ...
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 ...
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 ...
Triatoma sordida (Hemiptera, Triatominae) from La Paz, Bolivia: an incipient species or an intraspecific chromosomal polymorphism?
(2021-12-01)
Background: Triatoma sordida is one of the main Chagas disease vectors in Brazil. In addition to Brazil, this species has already been reported in Bolivia, Argentina, Paraguay, and Uruguay. It is hypothesized that the ...
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. ...
