Weighting of sensory cues reflect changing patterns of visual investment during ecological divergence in Heliconius butterflies.

The paper shows that Heliconius butterflies with greater visual neural investment preferentially use visual cues over olfactory cues in conflicting sensory environments.

Divergent warning patterns influence male and female mating behaviours in a tropical butterfly

The paper examines how divergent warning coloration patterns influence mating behaviors in male and female Heliconius butterflies, finding that both sexes prefer conspecific coloration but only male coloration affects mating success.

Adaptive introgression of a visual preference gene

The paper shows two Heliconius butterfly species evolved similar visual mating preferences through hybridization, linking a gene to behavior.

Parallel shifts in flight-height associated with altitude across incipient Heliconius species

The paper examines flight-height variation in Heliconius butterflies during speciation, finding parallel trait shifts linked to altitude and environmental selection.

Genomic evidence reveals three sequential W-autosome fusions in Heliconius butterflies

The paper identifies three sequential W-autosome fusions in Heliconius butterflies, revealing their role in adaptive radiation and sex chromosome evolution.

Does sexual conflict contribute to the evolution of novel warning patterns?

This study investigates whether sexual conflict contributes to the diversification of warning patterns in Heliconius butterflies, finding that sexual conflict can assist pattern diversification but genetic architecture and sex-specific costs also play roles.

Repeated genetic adaptation to high altitude in two tropical butterflies

This study identifies genetic regions under selection in two tropical butterflies adapted to high altitude, showing that standing variation and introgression from high-altitude specialists contribute to parallel adaptation.

Balancing selection at a wing pattern locus is associated with major shifts in genome-wide patterns of diversity and gene flow in a butterfly

The paper examines how balancing selection at a wing pattern locus in butterflies affects genome-wide diversity and gene flow, finding higher diversity and lower geographic structure in polymorphic populations.

Light environment influences mating behaviours during the early stages of divergence in tropical butterflies

This study shows that light conditions affect mating behaviors in Heliconius butterflies, with differences in visual attraction contributing to low-level assortative mating.

Multiple introductions, regional spread and local differentiation during the first week of COVID-19 epidemic in Montevideo, Uruguay

The paper uses genomic data to show multiple early introductions and regional spread of SARS-CoV-2 in Uruguay during the first week of the epidemic.

Mullerian mimicry of a quantitative trait despite contrasting levels of genomic divergence and selection

The paper examines parallel divergence in wing coloration between two butterfly species, showing similar geographic cline positions but differing cline widths, influenced by selection and dispersal factors.

Chemical signals act as the main reproductive barrier between sister and mimetic Heliconius butterflies

The paper identifies chemical signals as the primary reproductive barrier between two closely related, co-mimic Heliconius butterfly species.

Species specificity and intraspecific variation in the chemical profiles of Heliconius butterflies across a large geographic range

The paper examines chemical profile divergence in Heliconius butterflies, finding strong interspecific differences and some intraspecific variation, with implications for species recognition.

Classic and introgressed selective sweeps shape mimicry loci across a butterfly adaptive radiation

The paper analyzes genome sequences from Heliconius butterflies to show selection on color pattern loci, identifying both classic and introgressed selective sweeps.

Genomic architecture and introgression shape a butterfly radiation

The paper uses a low-cost genome assembly strategy to study Heliconius butterfly evolution, finding that introgression, not incomplete lineage sorting, explains most non-canonical genetic histories.

Recombination rate variation shapes barriers to introgression across butterfly genomes

The paper examines how recombination rate variation influences introgression barriers in butterfly genomes, finding that recombination rates predict introgression rates and that long chromosomes have stronger barriers.

Gene flow and Andean uplift shape the diversification of Gasteracantha cancriformis (Araneae: Araneidae) in Northern South America

This study examines how the Andean uplift and gene flow influenced the diversification of Gasteracantha cancriformis, finding two distinct clades with historical divergence despite gene flow.

Patterns of Z chromosome divergence among Heliconius species highlight the importance of historical demography

The paper examines Z chromosome divergence in Heliconius butterflies, showing demographic changes can explain increased divergence, but also identifies cases of reduced gene flow on the Z chromosome.

What shapes the continuum of reproductive isolation? Lessons from Heliconius butterflies.

This study examines reproductive isolation in Heliconius butterflies, finding that increased divergence leads to stronger barriers, with wing pattern being important early on but not essential for speciation.
