Abstract Hybridization allows adaptations to be shared among lineages and may trigger the evolution of new species 1,2 . However, convincing examples homoploid hybrid speciation remain rare because it is challenging demonstrate that hybridization was crucial in generating reproductive isolation 3 Here we combine population genomic analysis with quantitative trait locus mapping species-specific traits examine a case Heliconius butterflies. We show elevatus sympatric both parents has persisted...
Identifying the traits causing reproductive isolation and order in which they evolve is fundamental to understanding speciation. Here, we quantify prezygotic intrinsic postzygotic among allopatric, parapatric, sympatric populations of butterflies Heliconius elevatus pardalinus. Sympatric from Amazon (H. H. p. butleri) exhibit strong rarely mate captivity; however, hybrids are fertile. Allopatric Andes sergestus) freely when brought together captivity, but female F1 sterile. Parapatric both...
Predation is expected to promote uniformity in the warning coloration of defended prey, but also mimicry convergence between aposematic species. Despite selection constraining both colour-pattern and population divergence, many animals display numerous geographically structured populations with distinct signal. Here, we explore extent phenotypic variation sympatric species Ranitomeya poison frogs test for theoretical expectations on mimetic signals. We demonstrate that signal are highly...
Las interacciones depredador-presa son fundamentales para comprender la dinámica ecológica en los ecosistemas. El objetivo del presente artículo es reportar un evento de predación rana arborícola Boana lanciformis por parte serpiente loro, Leptophis ahaetulla. se documentó el 13 febrero 2022 río Callería, región Ucayali, Perú, donde observó y registró comportamiento L. ahaetulla depredando a B. durante 15 minutos. Se que engulló primero cabeza rana, mientras ésta intentaba liberarse moviendo...
La Amazonía peruana cuenta con una vasta diversidad de aves. Sólo en Loreto existen aproximadamente 1 040 especies, algunas ellas categoría amenaza. presente investigación se realizó entre mayo y junio 2023 el objetivo observar, registrar e identificar la especies aves presentes campus Universidad Nacional Autónoma Alto Amazonas sus alrededores. Se emplearon métodos observación directa, auditiva playback haciendo uso equipos como binoculares, cámara digital bocina para las identificaron un...
