The roles of hybridization and habitat fragmentation in the evolution of Brazil’s enigmatic longwing butterflies, Heliconius nattereri and H. hermathena

BMC Biology, 2020
Background Heliconius butterflies are widely distributed across the Neotropics and have evolved a stunning array of wing color patterns that mediate Müllerian mimicry and mating behavior.

Transmisssion Dynamics of Enterococcus spp. Throughout the Heliconius erato phyllis (Lepidoptera; Nymphalidae) Life Cycle [PDF]

Environ Microbiol Rep
Enterococcus spp. dominate the gut microbiota of Heliconius erato phyllis, transmitted horizontally via host plants (Passiflora suberosa) and persisting through development. Multidrug‐resistant strains were found in larvae and plants, suggesting environmental reservoirs of antimicrobial resistance. This study reveals key microbial transmission dynamics

Multi-allelic major effect genes interact with minor effect QTLs to control adaptive color pattern variation in Heliconius erato. [PDF]

PLoS ONE, 2013
Recent studies indicate that relatively few genomic regions are repeatedly involved in the evolution of Heliconius butterfly wing patterns. Although this work demonstrates a number of cases where homologous loci underlie both convergent and divergent ...

Gene flow and the genealogical history of Heliconius heurippa [PDF]

BMC Evolutionary Biology, 2008
La mariposa neotropical Heliconius heurippa tiene un patrón de color híbrido, que también contribuye al aislamiento reproductivo, lo que la convierte en un ejemplo probable de especiación híbrida. Aquí utilizamos análisis filogenéticos y basados en coalescencia de datos de secuencias multilocus para investigar el origen de H. heurippa. Secuenciamos una

A conserved supergene locus controls colour pattern diversity in Heliconius butterflies [PDF]

, 2006
We studied whether similar developmental genetic mechanisms are involved in both convergent and divergent evolution. Mimetic insects are known for their diversity of patterns as well as their remarkable evolutionary convergence, and they have played an ...

EST analysis of male accessory glands from Heliconius butterflies with divergent mating systems

BMC Genomics, 2008
Background Heliconius butterflies possess a remarkable diversity of phenotypes, physiologies, and behaviors that has long distinguished this genus as a focal taxon in ecological and evolutionary research.

Male sex pheromone components in Heliconius butterflies released by the androconia affect female choice [PDF]

PeerJ, 2017
Sex-specific pheromones are known to play an important role in butterfly courtship, and may influence both individual reproductive success and reproductive isolation between species.

Environmental Drivers of Diversification and Hybridization in Neotropical Butterflies

Frontiers in Ecology and Evolution, 2021
Studying how the environment shapes current biodiversity patterns in species rich regions is a fundamental issue in biogeography, ecology, and conservation. However, in the Neotropics, the study of the forces driving species distribution and richness, is

Comparative population genetics of mimetic Heliconius butterflies in an endangered habitat; Brazil's Atlantic Forest

BMC Genetics, 2011
Background Brazil's Atlantic Forest is a biodiversity hotspot endangered by severe habitat degradation and fragmentation. Habitat fragmentation is expected to reduce dispersal among habitat patches resulting in increased genetic differentiation among ...

Genetic evidence for hybrid trait speciation in heliconius butterflies. [PDF]

PLoS Genetics, 2010
Homoploid hybrid speciation is the formation of a new hybrid species without change in chromosome number. So far, there has been a lack of direct molecular evidence for hybridization generating novel traits directly involved in animal speciation ...
