The collective-risk social dilemma and the prevention of simulated dangerous climate change
Will a group of people reach a collective target through individual contributions when everyone suffers individually if the target is missed? This “collective-risk social dilemma” exists in variousExpand

Female sticklebacks count alleles in a strategy of sexual selection explaining MHC polymorphism
The origin and maintenance of polymorphism in major histocompatibility complex (MHC) genes in natural populations is still unresolved. Sexual selection, frequency-dependent selection by parasites andExpand

The Major Histocompatibility Complex, Sexual Selection, and Mate Choice
AbstractTo maintain sexual reproduction, recombination of good genes through selective mate choice must achieve a twofold genetic benefit in each generation. “Fragrant” immune genes of the majorExpand

TIT FOR TAT in sticklebacks and the evolution of cooperation
The problems of achieving mutual cooperation can be formalized in a game called the Prisoner's Dilemma in which selfish defection is always more rewarding than cooperation1. If the two protagonistsExpand

Mate choice decisions of stickleback females predictably modified by MHC peptide ligands.
Sexual selection has been proposed as one mechanism to explain the maintenance of high allelic diversity in MHC genes that control the extent of resistance against pathogens and parasites in naturalExpand

Female sticklebacks use male coloration in mate choice and hence avoid parasitized males
AN important problem in evolutionary biology since the time of Darwin has been to understand why females preferentially mate with males handicapped by secondary sexual ornaments1–3. One hypothesis ofExpand

Human strategy updating in evolutionary games
We present a way to measure such strategy update rules in a behavioral experiment. Expand

Risk of Predation of Parasitized Sticklebacks (Gasterosteus Aculeatus L.) Under Competition for Food
Three-spined sticklebacks which were either unparasitized, heavily infested by plerocercoids of the cestode Schistocephalus solidus, or parasitized by the sporozoan Glugea anomala were singly offeredExpand

Optimal growth strategies of larval helminths in their intermediate hosts
We consider optimal growth of larval stages in complex parasite life cycles where there is no constraint because of host immune responses. Our model predicts an individual's asymptotic size in itsExpand

MHC‐based mate choice combines good genes and maintenance of MHC polymorphism
Polymorphic genes of the major histocompatibility complex (MHC) are regarded as essential genes for individual fitness under conditions of natural and sexual selection. To test this hypothesis, weExpand
