Evolutionary quantitative genetics of nonlinear developmental systems.
TL;DR: A system for characterizing key quantitative parameters in nonlinear developmental systems, which yields expressions for quantities such as trait means and phenotypic and genetic covariance matrices is outlined and applied to generating a new hypothesis for why direct stabilizing selection is rarely observed.

Multilevel and sex-specific selection on competitive traits in North American red squirrels.

TL;DR: This work quantified multilevel natural selection on two traits, postnatal growth rate and birth date, in a population of North American red squirrels and demonstrated the importance of considering multileVEL and sex‐specific selection in wild species, including those that are territorial and sexually monomorphic.
Journal ArticleDOI
The effect of multiple inseminations on the evolution of social behaviors in diploid and haplo-diploid organisms.
TL;DR: Hamilton's rule is shown to specify the necessary and sufficient conditions for selection among kin groups to over-ride individual selection within kin groups, illustrating that individual selection always operates against the evolution of social behaviors.

The Inclusive Fitness Controversy: Finding a Way Forward
TL;DR: This paper argues that criticisms of the regression-based version of Hamilton's rule, although they undermine its use for predictive purposes, do not undermined its use as an organizing framework for social evolution research.

Hierarchical levels of spatial structure and their consequences for the evolution of sex allocation in mites and other arthropods.
TL;DR: Extended versions of the haystack model are used and it is shown that, although local density dependence in theHaystack population diminishes the sex ratio bias, strongly female-biased sex ratios are still possible if foundress numbers are low, and that substructure in the hay stack by subdivision into one-generation mating groups promotes the female bias.
