Kin selection in density regulated populations.
TL;DR: A simple genetic model is employed to examine the conditions under which the interaction of localdensity regulation and kin selection can maintain a stable polymorphism, and the results are applied to two biological cases in which local density regulation may be influencing the direction of phenotypic plasticity in group advantageous characters.

Evolutionary stability under the replicator and the gradient dynamics
Peter D. Taylor,Troy Day +1 more
TL;DR: Under the assumption of normality, it is found that the mean and variance dynamics are essentially identical under the two models and these are related to the ESS and convergence stability conditions.

Analyzing the effects of species gain and loss on ecosystem function using the extended Price equation partition
Jeremy W. Fox,Benjamin Kerr +1 more
TL;DR: A novel extension of the Price equation is used to separate effects of species loss from those of species gain; species gain is analogous to migration in evolution, and provides a highly-general partitioning of the factors affecting ecosystem function.

Parsimony pressure made easy
TL;DR: This paper first reconsider the size evolution equation for genetic programming developed in [26] and rewrite it in a form that shows its direct relationship to Price's theorem, and derives theoretical results that show how to practically and optimally set the parsimony coefficient dynamically during a run so as to achieve complete control over the growth of the programs in a population.

Natural Selection: I: Variable Environments and Uncertain Returns on Investment
TL;DR: In this article, the authors present a concise introduction to the two key aspects of the theory of relative success and the hierarchical structure of variability in populations, and place particular problems in their proper relation to the general theory.
