The evolution of environmentally mediated social interactions and posthumous spite under isolation by distance

This paper analyzes the evolution of environmentally mediated social interactions and posthumous spite in a spatially structured population under isolation by distance.

Evolution of semi-Kantian preferences in two-player assortative interactions with complete and incomplete information and plasticity

This study models the evolution of semi-Kantian preferences in two-player interactions under different information and plasticity conditions, finding varying stable values for the Kantian coefficient.

Prior flavivirus immunity skews the yellow fever vaccine response to expand cross-reactive antibodies with increased risk of antibody dependent enhancement of Zika and dengue virus infection

This study shows that prior TBEV immunity alters the YF17D vaccine response, leading to cross-reactive antibodies that increase the risk of ADE for dengue and Zika.

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.

Hamilton's rule, the evolution of behavior rules and the wizardry of control theory

The paper derives a first-order condition for evolutionary stability of behavior rules using Hamilton's rule and control theory, applicable to multidimensional traits and neural/gene network evolution.

On the interpretation of the operation of natural selection in class-structured populations

The paper decomposes allele-frequency change in class-structured populations to isolate the effects of natural selection from class transmission.

Life history and deleterious mutation rate coevolution

This study develops a mathematical model to analyze how life history traits and deleterious mutation rates coevolve, finding that higher environmental mutagen exposure leads to increased germline maintenance and faster life histories.

Evolution of warfare by resource raiding favors polymorphism in belligerence and bravery

The paper models co-evolution of traits related to resource raiding and shows disruptive selection favors social polymorphism in belligerence and bravery.

Structure and dynamics of the chromatin remodeler ALC1 bound to a PARylated nucleosome

This study determines the structure of ALC1 bound to a PARylated nucleosome using cryo-EM, revealing intermediate states and functional roles in nucleosome remodeling.

Metacommunities, fitness and gradual evolution

The paper analyzes the evolution of a quantitative trait in a structured species within a metacommunity, showing that weak selection reduces complex dynamics to a single differential equation determining allele frequency change.

Hamilton's rule, gradual evolution, and the optimal (feedback) control of phenotypically plastic traits

The paper derives a marginal version of Hamilton's rule for function-valued traits and uses optimal control theory to analyze their evolution under different feedback mechanisms.

Invasion implies substitution in ecological communities with class-structured populations

The paper demonstrates that the 'invasion implies substitution' principle generalizes to structured ecological communities using geometric singular perturbation methods.

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.

Mechanism of DNA surface exploration and operator bypassing during target search

This study uses SMCT-FCS to show LacI slides on DNA, bypassing target sequences by hopping out of the DNA groove, revealing a speed-accuracy trade-off in target search.

When do individuals maximize their inclusive fitness?

The paper examines conditions under which individuals maximize inclusive fitness in class-structured populations and relates this to gene-centered adaptation.

Evolution of preferences in structured populations: genes, guns, and culture

The paper analyzes how preferences evolve in structured populations, showing how group size, migration, conflict risk, and cultural loyalty influence self-interest, Kantian motives, and other-regarding preferences.

An evolutionary quantitative genetics model for phenotypic (co)variance under limited dispersal, with an application to socially synergistic traits

The paper develops a quantitative genetics model to study phenotypic (co)variance under limited dispersal, showing how kin selection affects trait correlations in socially synergistic traits.

Sex allocation conflict and sexual selection throughout the lifespan of eusocial colonies

This study develops a model showing how dynamic resource allocation strategies in eusocial insect colonies are influenced by queen-worker conflict and sexual selection over time.

Linking micro and macroevolution in the presence of migration

This paper introduces an OU model that incorporates migration during speciation to study trait evolution and phenotypic disparity across phylogenies, showing migration reduces disparity and affects inference.

Eco-evolutionary dynamics in metacommunities: ecological inheritance, helping within- and harming between-species

The paper develops an approximation to study eco-evolutionary dynamics in dispersal-limited communities, showing how ecological inheritance influences the evolution of helping within-species and harming between-species.

Invasion fitness for gene-culture co-evolution in family-structured populations and an application to cumulative culture under vertical transmission

This paper analyzes gene-culture co-evolution in family-structured populations, showing vertical transmission increases adaptive information through kin selection but is limited by learning-reproduction trade-offs.
