Foraging for locally and spatially varying resources: Where exploitation competition, local adaptation and kin selection meet

The paper uses mathematical modeling to show that locally and spatially disruptive selection often act together to promote polymorphism in consumer populations, but kin competition can inhibit this under limited dispersal.

Consequences of life-cycle complexity to the potential for evolutionary branching

This study investigates how complex life-cycles affect evolutionary branching potential in a consumer with two life-stages, finding that complexity can promote diversification and character displacement.

Invasion and maintenance of meiotic drivers in populations of ascomycete fungi

The paper develops a population genetic model to study the invasion and coexistence of meiotic drivers in ascomycete fungi, focusing on spore killing and its dependence on ploidy, selfing rate, and spore killing efficiency.

The components of directional and disruptive selection in heterogeneous group-structured populations

This paper derives expressions for directional and disruptive selection coefficients in group-structured populations using perturbation expansions and introduces individual k-fitness to simplify calculations.

The efficacy of sexual selection under environmental change

The paper shows that sexual selection becomes less effective under environmental stress, reducing its ability to aid adaptation.
