Increased evolutionary rate in the Z-chromosome of Morpho butterflies and implications for speciation.

This study examines the Z-chromosome evolution in Morpho butterflies, finding increased genomic rearrangements and positive selection, suggesting a role in speciation through pre- and post-zygotic isolation.

Bending the course of evolution: how mutualistic interactions affect macroevolutionary dynamics of diversification in mimetic butterflies.

This study examines how mutualistic Mullerian mimicry influences macroevolutionary diversification patterns in Ithomiini butterflies, finding that color pattern age drives species richness but not phylogenetic diversity.

Convergence in sympatric swallowtail butterflies reveals ecological interactions as a key driver of worldwide trait diversification.

This study shows sympatry promotes convergence in swallowtail butterfly wing color patterns, with stronger effects on females, highlighting ecological interactions' role in trait diversification.

Which cues are sexy? The evolution of mate preference in sympatric species reveals the contrasted effect of adaptation and reproductive interference.

This paper models how mate preferences evolve in sympatric species, showing that preferences may target adaptive traits or neutral traits depending on heterospecific interactions and sensory trade-offs.

Influence of mimicry on extinction risk in Aculeata: a theoretical approach.

This study uses a population dynamics model to show Mullerian mimicry reduces extinction risk in Aculeata but depends on sex ratios and can be destabilized by dual sex-limited mimicry.

Evidence of attack deflection suggests adaptive evolution of wing tails in butterflies

The paper investigates the adaptive evolution of hindwing tails in butterflies by showing they are more frequently attacked and damaged, supporting their role in deflection.

Origin and persistence of polymorphism in loci targeted by disassortative preference: a general model

The paper develops a theoretical model to show how disassortative mating can generate and maintain polymorphism at targeted loci, depending on the relationship between allelic divergence and reproductive advantage.

Uncovering the effects of Müllerian mimicry on the evolution of conspicuousness in colour patterns

This study models how Müllerian mimicry influences the evolution of conspicuousness in defended prey species, showing that less conspicuous patterns are generally favored unless they impair mimicry.

Evolutionary origins of sexual dimorphism : Lessons from female-limited mimicry in butterflies.

The paper uses a mathematical model to compare evolutionary hypotheses for female-limited mimicry in butterflies, showing divergence in female traits is not solely due to natural selection.

Gliding in the Amazonian canopy: adaptive evolution of flight in Morpho butterflies

This study compares flight adaptations in canopy and understory Morpho butterflies, showing canopy species have more efficient gliding flight through distinct combinations of wing shape and behavior.

The limits of evolutionary convergence in sympatry: reproductive interference and historical constraints leading to local diversity in warning traits

The paper develops a mathematical model to show that reproductive interference and historical constraints limit the convergence of warning traits in sympatric species, leading to imperfect mimicry or divergence.

Sex, Competition and Mimicry : an eco-evolutionary model reveals how ecological interactions shape the evolution of phenotypes in sympatry.

This study uses an eco-evolutionary model to show how ecological interactions influence phenotypic divergence and convergence in sympatric species, particularly through reproductive interference and mimicry.

Convergent morphology and divergent phenology: unravelling the coexistence of mimetic Morpho butterfly species

This study shows that temporal segregation in patrolling activity allows co-mimetic Morpho butterfly species to coexist despite phenotypic similarity and interspecific interactions.

Evolution and genetic architecture of disassortative mating at a locus under heterozygote advantage

This study models the evolution of disassortative mating under heterozygote advantage at a locus under balancing selection, showing that genetic architecture and selection regimes influence its emergence.

When do opposites attract? A model uncovering the evolution of disassortative mating

The paper models the evolution of disassortative mating and finds that heterozygote advantage and negative frequency-dependent viability selection promote its fixation, but also create a negative feedback loop limiting its prevalence.

Convergence in sympatry: evolution of blue-banded wing pattern in Morpho butterflies

The paper tests if species interactions drive convergence in wing patterns among sympatric Morpho butterflies by comparing phenotypic distances in sympatric and allopatric populations.

Mutation accumulation in chromosomal inversions maintains wing pattern polymorphism in a butterfly

The paper shows chromosomal inversions maintain wing pattern polymorphism in butterflies by accumulating recessive mutations that prevent fixation despite ecological advantages.

Artificial selection on male size depletes genetic variance but not covariance of life history traits in the yellow dung fly

Balancing selection via life-history trade-offs maintains an inversion polymorphism in a seaweed fly

The paper shows that a chromosomal inversion in seaweed flies is maintained by life-history trade-offs and antagonistic pleiotropy, revealing balancing selection mechanisms.

Generalisation behaviour of predators toward warning signals displayed by harmful prey: answers from a videogame played by humans.

This study uses a video game to investigate human generalisation behaviour toward warning signals of harmful prey, finding that learning is more efficient in simpler communities and that visual similarity affects prey vulnerability.
