Genetic drift decouples Fisherian trait-preference coevolution from genetic correlations in finite populations

This study shows that genetic drift in finite populations can decouple trait-preference genetic correlations from coevolution in Fisherian sexual selection, explaining weak empirical correlations.

The probability of evolutionary rescue with competition: scaling-up from a single species to a community

This study examines how competition affects evolutionary rescue in ecological communities, showing that survival interference reduces rescued species but weakens with diversity.

Eco-evolutionary feedbacks generate bistability in population persistence under gradual environmental change

The paper shows that population persistence under gradual environmental change can exhibit bistability, depending on initial population size and genetic variance, beyond just the critical extinction rate.

When does sexual selection through mate choice deplete versus exaggerate genetic variation: is there a lek paradox?

This paper uses mathematical models to show sexual selection through mate choice can increase or minimally reduce genetic variation in display traits and preferences, resolving the lek paradox.

Direct selection under resource allocation trade-offs enables the evolution of obligate and facultative sexuality

This study shows that resource allocation trade-offs between sexual and asexual reproduction can enable direct selection for obligate or facultative sexuality, depending on fertility returns and initial allocations.

When does the probability of evolutionary rescue increase with the strength of selection?

The paper examines how stronger selection affects evolutionary rescue across different population genetic models and finds that it can only facilitate rescue if it increases the absolute fitness of the rescue homozygote.

When sexual selection meets genetic drift: the coevolution of male traits and female preferences in finite populations

This study examines how sexual selection and genetic drift interact in finite populations, showing their impact on trait-preference correlations and allele fixation.

Analysis of the effects of mating systems on lineage diversification across multiple genera

The paper analyzes how mating systems affect lineage diversification across 27 genera, finding outcrossing lineages diversify faster than selfing ones, with mixed results across genera.
