The evolution of dependence and cohesion in incipient endosymbioses

This paper models the evolution of mutual dependence and reproductive cohesion in endosymbioses, showing how population dynamics and asymmetries affect the transition to collective survival.

A stochastic analysis of the interplay between antibiotic dose, mode of action, and bacterial competition in the evolution of antibiotic resistance

This paper develops a stochastic model to analyze how antibiotic dose, mode of action, and bacterial competition influence resistance evolution, finding that resistance survival depends on density regulation and drug type.

Blochmannia endosymbionts reduce brood rearing success in a carpenter ant (Camponotus sp.)

This study shows antibiotic treatment reducing Blochmannia endosymbionts in carpenter ants leads to lower brood development success but higher brood rearing success in treated subcolonies.

Revisiting the number of self-incompatibility alleles in finite populations: from old models to new results

The paper revisits models of self-incompatibility allele dynamics in plant populations, resolves a long-standing debate, and provides new methods for estimating population size from S-allele frequencies.

The effect of habitat choice on evolutionary rescue in subdivided populations

This study models how habitat choice affects evolutionary rescue in subdivided populations, finding that dispersal rates and immigration biases influence rescue probability in three distinct phases.

The search for sexually antagonistic genes: Practical insights from studies of local adaptation and statistical genomics

This paper evaluates methods for identifying sexually antagonistic genes by integrating concepts from local adaptation and statistical genomics, applying them to genome data and experimental approaches.

Evolution of mating types in finite populations: the precarious advantage of being rare

The paper analyzes the evolution of mating types in finite populations, showing that rare types have both deterministic advantages and stochastic risks, leading to a maximum of approximately N1/3 mating types for intermediate population sizes.

Invasion and extinction dynamics of mating types under facultative sexual reproduction

The paper develops a population genetic model to study mating type dynamics under facultative sexual reproduction, finding that the average rate of sexual reproduction correlates with the number of mating types.

Disentangling eco-evolutionary effects on trait fixation

The paper analyzes trait fixation in a stochastic Lotka-Volterra model with demographic fluctuations and frequency-dependent selection, showing that ecological and evolutionary effects are intertwined and cannot be separated.
