The evolutionary age-range size relationship is modulated by insularity and dispersal in plants and animals

The paper examines the relationship between evolutionary age and range size in species, finding that age correlates with larger ranges but this effect is modulated by insularity and dispersal ability.

From Fossils to Living Canids: Two Contrasting Perspectives on Biogeographic Diversification

The paper extends a speciation model to include extinct species in Canidae phylogeny, finding contrasting diversification patterns between extant and complete trees.

Resource sharing leads to the emergence of division of labour

This study shows that resource sharing among initially identical individuals leads to the spontaneous emergence of division of labour through task specialisation and nutritional differences.

Modelling the spatial dynamics of oncolytic virotherapy in the presence of virus-resistant tumor cells

This study models the spatial dynamics of oncolytic virotherapy with virus-resistant tumor cells, identifying factors that influence therapeutic outcomes and failure mechanisms.

Detecting phylodiversity-dependent diviersification with a general phylogenetic inference framework

The paper introduces a new statistical method to analyze phylodiversity-dependent diversification using Monte Carlo Expectation-Maximization and applies it to 14 phylogenies, finding that phylogenetic divergence can spur speciation despite reduced species richness.

Estimating the time since admixture from phased and unphased molecular data

This paper extends admixture dating methods to unphased data and shows improved accuracy for smaller populations and ancient admixture times using simulated and empirical datasets.

Nucleotide substitutions during speciation may explain substitution rate variation

The paper shows that elevated mutation rates during speciation can explain variation in substitution rates across evolutionary lineages.

Alternative phage-host interaction in Lactococcus lactis: the carrier state drives rapid evolution of phages

The paper shows that a bacteriophage in Lactococcus lactis can transition from a carrier state to an active lytic cycle upon infection by a second phage, leading to rapid genomic evolution and host range diversification.

Recombining your way out of trouble: The genetic architecture of hybrid fitness under environmental stress

This study investigates hybrid fitness in yeast under environmental stress, finding selection against heterozygosity and positive epistasis between divergent species.

A simple spatially explicit neutral model explains range size distribution of reef fishes

The paper uses a spatially explicit neutral model to show dispersal ability explains range size variation in reef fishes.
