A note on discretising Keyfitz entropy

This paper introduces a new discretisation of Keyfitz entropy to accurately reflect mortality rate patterns in discrete-time demographic data, addressing biases in the original method.

Positive fitness effects help explain the broad range of Wolbachia prevalences in natural populations

This study shows that direct fitness benefits from Wolbachia can explain stable low-frequency infections in natural populations, challenging classical models that predict near-fixation or extinction.

Extrinsic mortality and senescence: a guide for the perplexed

The paper provides heuristics and models to clarify when George Williams' prediction about extrinsic mortality and senescence holds, and why conflicting results may arise.

The demographic costs of sexually antagonistic selection in partially selfing populations

This study examines the demographic impacts of sexually antagonistic selection in partially selfing populations and finds that inbreeding depression and population growth rates significantly affect the maintenance of SA polymorphism.
