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.

The effectiveness of pseudomagic traits in promoting premating isolation

The paper shows that pseudomagic trait complexes can promote stronger premating isolation than magic traits by increasing assortative mating preferences when polymorphism is maintained.

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.

Volatile social environments can favour investments in quality over quantity of social relationships

The paper models how volatile social environments can favor a focused strategy of forming few strong social bonds over a diversifying strategy, using antagonistic pleiotropy theory.

Admixture can readily lead to the formation of supergenes

The paper shows that admixture can lead to supergene formation through the evolution of chromosomal inversions with recessive fitness costs.

Costs of choosiness can promote reproductive isolation in parapatry

The paper shows that weak costs of female choosiness can promote reproductive isolation in parapatric speciation by reducing indirect selection against strong choosiness.

Transmissible cancers and the evolution of sex under the Red Queen hypothesis

This study evaluates whether transmissible cancers could drive the evolution of sex under the Red Queen hypothesis, finding that horizontal transmission reduces fluctuating selection, while vertical transmission promotes sex through similarity selection.

Coevolution of male and female mate choice can destabilize reproductive isolation

This study shows that coevolving male and female mate choice can lead to periodic hybridization and destabilize reproductive isolation through deterministic preference cycling driven by stochasticity.
