Survival cost sharing among altruistic full siblings in Mendelian population [PDF]
BMC Ecology and EvolutionBackground We focus on Haldane’s familial selection in monogamous families in a diploid population, where the survival probability of each sibling is determined by altruistic food sharing with its siblings during starvation.

Hamilton's rule and the causes of social evolution. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2014 Hamilton's rule is a central theorem of inclusive fitness (kin selection) theory and predicts that social behaviour evolves under specific combinations of relatedness, benefit and cost. This review provides evidence for Hamilton's rule by presenting novel syntheses of results from two kinds of study in diverse taxa, including cooperatively breeding ...

Hamilton's rule confronts ideal free habitat selection. [PDF]
Proc Biol Sci, 2001 If individuals occupy habitats in a way that maximizes their fitness, if they are free to occupy the habitats they choose and if fitness declines with population density, then their abundance across habitats should follow an ideal free distribution.

Kin Competition Drives the Evolution of Earlier Metamorphosis [PDF]
Ecology and EvolutionMetamorphosis, the discrete morphological change between postembryonic life stages, is widespread across the animal kingdom. The suggested advantages of metamorphosis have usually been framed in terms of population benefits, i.e., ecological explanations.

Altruism can proliferate through population viscosity despite high random gene flow. [PDF]
PLoS ONE, 2013 The ways in which natural selection can allow the proliferation of cooperative behavior have long been seen as a central problem in evolutionary biology. Most of the literature has focused on interactions between pairs of individuals and on linear public

Genetic polymorphisms between altruism and selfishness close to the Hamilton threshold rb = c [PDF]
Royal Society Open Science, 2017 Genes that in certain conditions make their carriers altruistic are being identified, and altruism and selfishness have shown to be heritable in man. This raises the possibility that genetic polymorphisms for altruism/selfishness exist in man and other ...

The Midpoint Rule as a Variational--Symplectic Integrator. I. Hamiltonian Systems [PDF]
, 2002 Numerical algorithms based on variational and symplectic integrators exhibit special features that make them promising candidates for application to general relativity and other constrained Hamiltonian systems.
