Infanticide as an evolutionarily stable strategy

Animal Behaviour, 1985
Abstract An evolutionarily stable strategies analysis of infanticide, expressed as two pure strategies, shows that the equilibrial frequency of infanticide depends on only two parameters: the relative advantage of infanticide when others are also infanticidal and the relative advantage of a non-infanticidal strategy if others are non-infanticidal ...

On the definition of an evolutionarily stable strategy

Journal of Theoretical Biology, 1987
An ESS must be able to withstand invasion by a small group. It is shown that there are (at least) two possible mathematical interpretations of this statement. In some important applications the two definitions of an ESS are equivalent, but this is not generally the case and a simple example is given to illustrate this.

Evolutionarily Stable Strategies for Consuming a Structured Resource

The American Naturalist, 2000
A general consumer-resource model assuming discrete consumers and a continuously structured resource is examined. We study two foraging behaviors, which lead to fixed and flexible patch residence times, in conjunction with a simple consumer energetics model linking resource consumption, foraging behavior, and metabolic costs. Results indicate a single,

A Discussion of Evolutionarily Stable Strategies

1990
Consideration of the question “What behaviours can be expected in stable biological populations?” leads first to a description of the classical ESS population model and determination of the two ESS conditions, formulated explicitly for the constant payoff matrix case, with examples. After discussing an instructive method of summarizing populations (the

Effect of Time Delay and Evolutionarily Stable Strategy

Journal of Theoretical Biology, 1997
In this paper, a simple two-phenotype model with time delay is investigated. The main results are that: (i) the stability of the interior equilibrium point of the pure strategy model not only depends on the property of the payoff matrix but also the effect of time delay; (ii) the conditions of the evolutionarily stable strategy in the two-phenotype ...

Conditions for evolutionarily stable strategies

Journal of Applied Probability, 1980
It is pointed out that the conditions given by Haigh (1975) for finding evolutionarily stable strategies corresponding to a given matrix are sufficient, but not always necessary. An example is given, and an amended version of the necessary and sufficient conditions is stated.

Evolutionarily stable strategies of migration in heterogeneous environments

Evolutionary Ecology, 1999
By means of a simulation model we are showing that the rates of migration can be related to avoidance of competition between relatives, especially in clonal organisms. This could result in a strong selective pressure for migration, even at a high cost. In addition, if the habitat is fragmented, migration can strongly affect local dynamics and result in

Good Strategy or Evolutionarily Stable Strategy?

2019
A strategy is an unconscious behavior program, a candidate for natural selection in competition with alternative strategies. The ‘evolutionarily stable strategy’ (ESS) is the result of Maynard Smith’s tailoring of the mathematics of game theory to fit the theory of evolution.

The distribution of evolutionarily stable strategies

Journal of Applied Probability, 1988
Suppose the n × n matrix A gives the payoffs for some evolutionary game, and its entries are the values of independent, identically distributed, continuous random variables. The distribution of the pattern of evolutionarily stable strategies for A will depend, if n ≧ 3, on this underlying distribution.

An evolutionarily stable strategy approach to indiscriminate spite

Nature, 1979
AN individual behaves spitefully when it harms itself in order to harm another individual more(1). Hamilton(1,2) predicted that spite may evolve if it is expressed only in those encounters that occur between individuals of less than average relatedness.
