Morphs, Dispersal Behavior, Genetic Similarity, and the Evolution of Cooperation

Genetic similarity owing to kin relationship is often invoked to explain the evolution of social cooperation. In this study, male color morphs of side-blotched lizards settle nonrandomly with respect to genetic similarity. Blue morphs tend to settle in close proximity to other blue morphs with high genetic similarity. Blue neighbors have three times the average fitness of blue males lacking such neighbors. Conversely, genetically similar males depress fitness of the orange morph. Moreover…

Co-evolution of dispersal with social behaviour favours social polymorphism
- BiologybioRxiv
- 2017
This model of co-evolution of dispersal and social behaviour shows that it readily leads to the emergence and maintenance of two broadly-defined social morphs: a sessile, benevolent morph expressed by individuals who tend to increase the fecundity of others within their group relative to their own; and a dispersive, self-serving morph.
Space use and genetic structure do not maintain color polymorphism in a species with alternative behavioral strategies
- BiologyEcology and evolution
- 2019
The results indicate potential weak barriers to gene flow between some morphs, potentially due to nonrandom pre‐ or postcopulatory mate choice or postzygotic genetic incompatibilities, but space use, spatial structure, and nonrandom mating do not appear to be primary mechanisms maintaining color polymorphism in this system, highlighting the complexity and variation in alternative strategies associated withcolor polymorphism.
Color-Biased Dispersal Inferred by Fine-Scale Genetic Spatial Autocorrelation in a Color Polymorphic Salamander
- Biology, Environmental ScienceThe Journal of heredity

Results show that genetic methods typically used for sex-biased dispersal can be used to investigate differences in dispersal between morphs that vary discretely in polymorphic populations, such as color morphs.
Morph-dependent resource acquisition and fitness in a polymorphic bird
- Biology, Environmental ScienceEvolutionary Ecology

Investigation of red and black head-colour morphs of the Gouldian finch found competitive asymmetries are important to relative selection among coexisting morphs, and are likely to contribute to the maintenance of alternative sympatric colour-morphs in wild populations.
Cooperation‐mediated plasticity in dispersal and colonization
- BiologyEvolution; international journal of organic evolution
- 2016
The experimental results should help to resolve the evolutionary conflict between cooperation and dispersal: cooperative individuals are expected to avoid kin‐competition by dispersing long distances, but maintain the benefits of cooperation by dispersed in small groups.
Kin-dependent dispersal influences relatedness and genetic structuring in a lek system
- Environmental SciencebioRxiv
- 2019
The results indicate that kin-dependent dispersal decisions and costs are factors driving the evolution of cooperative courtship and have a genetic footprint in wild populations.
Environment, but not genetic divergence, influences geographic variation in colour morph frequencies in a lizard
- BiologyBMC Evolutionary Biology
- 2015
Spatial variation in selection appears to play an important role in shaping morph frequency patterns in C. decresii, and selection associated with differences in local environmental conditions, combined with relatively low levels of gene flow, is expected to favour population divergence in morph composition, but may be counteracted by negative frequency-dependent selection favouring rare morphs.
Density and genetic relatedness increase dispersal distance in a subsocial organism.
- Environmental ScienceEcology letters
- 2013
It is found that both density and relatedness in the release patch increase dispersal distance and is the first experimental demonstration that kin competition can shape the whole distribution of dispersal distances in a population, and thus affect the geographical spread of disperseal phenotypes.
Self-recognition, color signals, and cycles of greenbeard mutualism and altruism.
- BiologyProceedings of the National Academy of Sciences of the United States of America
- 2006
It is shown that payoffs of cooperation depend on asymmetric costs of orange neighbors, and recognition and cooperation arise from genome-wide factors based on the mapping study of the location of genes responsible for self-recognition behavior, recognition of blue color, and the color locus.
The social evolution of dispersal with public goods cooperation
- BiologyJournal of evolutionary biology
- 2013
It is found both mathematically and experimentally that dispersal is always favoured when averagePatch occupancy is low, but when average patch occupancy is high, the presence of public goods cheats greatly alters selection for dispersal.

Density-dependent competition and selection on immune function in genetic lizard morphs
- BiologyProceedings of the National Academy of Sciences of the United States of America

Data from a natural lizard population (Uta stansburiana) showed that breeding females surrounded by many territorial neighbors had suppressed immune function, and the throat color of a female was genetically correlated with her daughter's immune responsiveness.
Microsatellite markers reveal the potential for kin selection on black grouse leks
- BiologyProceedings of the Royal Society of London. Series B: Biological Sciences

It is shown, using microsatellite analysis, that males but not females of a lekking bird (the black grouse, Tetrao tetrix) are genetically structured at the lek level, and this structuring has the consequence that males on any specific lek should be more related than expected by chance as indicated by genetic data.

It is shown that environmental changes that cause increased mobility in those highly altruistic species can beget selection‐driven self‐extinction, which may contribute to the rarity of social species.

Kinship affects morphogenesis in cannibalistic salamanders
- BiologyNature
- 1993
When tiger salamander larvae are reared in mixed-brood groups they are significantly more likely to develop the cannibal morphology and at an earlier age than siblings rearing in pure-sibship groups, and morphogenesis may be responsive to kinship in any species that facultatively develops structures that can be used against conspecifics as weaponry.
