Natural hybridization in heliconiine butterflies: the species boundary as a continuum
Background To understand speciation and the maintenance of taxa as separate entities, we need information about natural hybridization and gene flow among species. Results Interspecific hybrids occur regularly in Heliconius ...
Phylogenetic Discordance at the Specie Boundary: Comparative Gene Genealogies Among Rapidly Radiating Heliconius Butterlies
Recent adaptive radiations provide excellent model systems for understanding speciation, but rapid diversification can cause problems for phylogenetic inference. Here we use gene genealogies to investigate the phylogeny ...
Coevolución entre Heliconius y Passiflora: una búsqueda de evidencia desde su distribución geográfica y riqueza de especies
The adaptive diversification of plants and their herbivorous insects could be influenced by coevolutionary processes. The biotic relationship between Heliconius butterflies and their host plants Passiflora has been studied ...
Patterns of genetic and morphological diversity in the highly polymorphic Neotropical banner damselflies, Polythore (Polythoridae:Odonata)
(Universidad del RosarioBiologíaFacultad de Ciencias Naturales y Matemáticas, 2018)
Genetic divergence across populations can be favored by geographical and/or phenotypic processes. However, phenotype polymorphisms caused by natural and/or sexual selection can obscure patterns of genetic divergence due ...
