Evolution of spite versus evolution of altruism through a disbandment mechanism
In this study, we focus on the mechanism by which individuals choose to keep or stop the interaction according to the opponent's behavior. Using the evolutionary game theory, we investigate the evolution of altruism and spite under this mechanism. Our model revealed that the evolution of spite is less likely than the evolution of altruism.PMID:38387802 | DOI:10.1016/j.tpb.2024.02.008 (Source: Theoretical Population Biology)

Clade size distribution under neutral evolutionary models
Theor Popul Biol. 2024 Feb 15:S0040-5809(24)00013-3. doi: 10.1016/j.tpb.2024.02.004. Online ahead of print.ABSTRACTGiven a labeled tree topology t, consider a population P of k leaves chosen among those of t. The clade of P is the minimal subtree of t containing P and its size is given by the number of leaves in the clade. When t is selected under the Yule or uniform distribution among the labeled topologies of size n, we study the "clade size" random variable determining closed formulas for its probability mass function, its mean, and its variance. Our calculations show that for large n the clade size tends to be smaller ...

On multi-type Cannings models and multi-type exchangeable coalescents
Theor Popul Biol. 2024 Feb 15;156:103-116. doi: 10.1016/j.tpb.2024.02.005. Online ahead of print.ABSTRACTA multi-type neutral Cannings population model with migration and fixed subpopulation sizes is analyzed. Under appropriate conditions, as all subpopulation sizes tend to infinity, the ancestral process, properly time-scaled, converges to a multi-type coalescent sharing the exchangeability and consistency property. The proof gains from coalescent theory for single-type Cannings models and from decompositions of transition probabilities into parts concerning reproduction and migration respectively. The following section d...
