Evolutionary rescue via niche construction: Infrequent construction can prevent post-invasion extinction
Theor Popul Biol. 2023 Jun 14:S0040-5809(23)00036-9. doi: 10.1016/j.tpb.2023.06.002. Online ahead of print.ABSTRACTA population experiencing habitat loss can avoid extinction by undergoing genetic adaptation-a process known as evolutionary rescue. Here we analytically approximate the probability of evolutionary rescue via a niche-constructing mutation that allows carriers to convert a novel, unfavorable reproductive habitat to a favorable state at a cost to their fecundity. We analyze competition between mutants and non-niche-constructing wild types, who ultimately require the constructed habitats to reproduce. We find tha...

Cultural niche construction with application to fertility control: A model for education and social transmission of contraceptive use
This study investigates the evolution of a cultural trait, such as the acceptance of the idea of contraception, that is both vertically and horizontally transmitted within a homogeneous social network. Individuals may conform to the norm, and adopters of the trait have fewer progeny than others. In addition, adoption of this trait is affected by a vertically transmitted aspect of the cultural background, such as the preference for high or low levels of education. Our model shows that such cultural niche construction can facilitate the spread of traits with low Darwinian fitness while providing an environment that counterac...

Decomposition of disparities in life expectancy with applications to administrative health claims and registry data
In this study, we used Pollard's decomposition to evaluate the disease-related contributions to disparities in LE65 for two types of data with distinctly differing structures: population/registry and administrative claims. To do so, we analyzed Pollard's integral, which is exact by construction, and developed exact analytic solutions for both types of data without the need for numerical integration. The solutions are broadly applicable and easily implemented. Applying these solutions, we found that the largest relative contributions to geographic disparities in LE65 were chronic lower respiratory diseases, circulatory dise...

Adaptation of a quantitative trait to a changing environment: New analytical insights on the asexual and infinitesimal sexual models
Theor Popul Biol. 2023 May 11;152:1-22. doi: 10.1016/j.tpb.2023.04.002. Online ahead of print.ABSTRACTPredicting the adaptation of populations to a changing environment is crucial to assess the impact of human activities on biodiversity. Many theoretical studies have tackled this issue by modeling the evolution of quantitative traits subject to stabilizing selection around an optimal phenotype, whose value is shifted continuously through time. In this context, the population fate results from the equilibrium distribution of the trait, relative to the moving optimum. Such a distribution may vary with the shape of selection,...
