Abstract We study the spatial adaptive dynamics of a continuous trait that measures individual investment in altruism. Our study is based on an ecological model of a spatially heterogeneous population from which we derive an appropriate measure of fitness. The analysis of this fitness measure uncovers three different selective processes controlling the evolution of altruism: the direct physiological cost, the indirect genetic benefits of cooperative interactions, and the indirect genetic costs… 

Eco-evolutionary dynamics under limited dispersal: ecological inheritance, altruism within and spite between species

This work approximates the selection gradient on a quantitative trait that influences local community dynamics, assuming that such dynamics are deterministic with a stable fixed point, but incorporating the kin selection effects arising from demographic stochasticity.

Eco-Evolutionary Dynamics in Metacommunities: Ecological Inheritance, Helping within Species, and Harming between Species

The approximation of the selection gradient on a quantitative trait that influences local community dynamics is used to investigate the evolution of helping within species and harming between species when these behaviors influence demography and finds that altruistic helping evolves more readily when intraspecific competition is for material resources rather than for space.

Habitat saturation and the spatial evolutionary ecology of altruism

This work derives an expression for relatedness that takes into account both habitat saturation and the spatial structure of genetic variation, and provides a theoretical framework taking into account the interplay between demography and kin selection.

Eco-evolutionary dynamics in metacommunities : ecological inheritance , helping within-and harming between-species

Understanding selection on intraand inter-specific interactions that take place in dispersal-limited communities is a challenge for ecology and evolutionary biology. The problem is that local

For a given level of habitat saturation and with density‐dependent reproduction, it is found that the conditions for the evolution of helping should be more favorable in the survival altruism life cycle with a cost on fecundity, and more stringent in the FECundity altruismLife cycle withA cost on survival.

Adaptive Evolution of Social Traits: Origin, Trajectories, and Correlations of Altruism and Mobility

This study integrates previously separate lines of research by analyzing the joint evolution of altruism and mobility to unfold the network of selective pressures and derive how these depend on physiological costs, eco‐evolutionary feedbacks, and a complex interaction between the evolving traits.

Population viscosity can promote the evolution of altruistic sterile helpers and eusociality

It is shown that a sterile worker caste can be selected for even under the simplest life-cycle assumptions, which has relevant consequences for the understanding of the evolution of altruism in social organisms, as many social insects are characterized by limited dispersal and significant genetic population structure.


It is shown that, paradoxically, ecological constraints on altruism may ultimately be its strongest driver, and a two‐trait, coevolutionary adaptive dynamics model of social evolution in a genetically structured population with local resource competition is constructed.

The evolution of altruism and the serial rediscovery of the role of relatedness

An analysis of 43 evolutionary models in which altruism evolves and where the authors attribute the evolution of altruism to a pathway other than kin selection and/or deny the role of relatedness reveals that in every case the life cycle assumptions entail local reproduction and local interactions, thereby leading to interacting individuals being genetically related.



Invasion fitness and adaptive dynamics in spatial population models

This chapter's deterministic predictions of dispersal and altruism evolution based on spatial invasion fitness are in good agreement with stochastic individual-based simulations of the mutation-selection process acting on these traits.

The Unit of Selection in Viscous Populations and the Evolution of Altruism.

The Pair Approximation technique is used to derive explicit invasion conditions for rare mutants in populations with limited dispersal and the consequences for the evolution of dispersal are discussed and the method may be extended to study evolution in interacting populations.

The spatial spread of altruism versus the evolutionary response of egoists

An individual–based model of a viscous population shows that the ease with which altruism spreads in viscous populations is maintained despite countermeasures evolved by egoists.

Can altruism evolve in purely viscous populations?

A computer simulation model of ‘pure’ population viscosity is analysed, in which offspring are always deposited close to parents and no global mixing stage exists, which generates a high coefficient of relatedness among interacting individuals.

Population viscosity and the evolution of altruism.

A class of models is presented in which population density is permitted to fluctuate, so that patches of altruists are supported at a higher density than patches of non-altruists, and under these conditions, population viscosity can support the selection of both weak and strong altruism.

It is argued that a necessary first step for the evolution of cooperative breeding is a substructuring of the population into small, stable, social units; in most known cases these are extended-family units.

It is shown that with an inclusive fitness model, that the same result holds in a patchstructured population, thus opposing the evolution of local altruistic behaviour.

The Evolution of Cooperation in Spatially Heterogeneous Populations

A dynamical IPD model where temporal and spatial variations in the population are explicitly considered and accounts for the stochastic motion of individuals and the inherent nonrandomness of local interactions is developed.

A model is presented to account for the natural selection of what is termed reciprocally altruistic behavior. The model shows how selection can operate against the cheater (non-reciprocator) in the
