Caste load and the evolution of reproductive skew (2013)
Journal Article
Holman, L. (2014). Caste load and the evolution of reproductive skew. American Naturalist, 183(1), 84-95. https://doi.org/10.1086/674052

Reproductive skew theory seeks to explain how reproduction is divided among group members in animal societies. Existing theory is framed almost entirely in terms of selection, though nonadaptive processes must also play some role in the evolution of...

The evolution of genomic imprinting: costs, benefits and long-term consequences (2013)
Journal Article
Holman, L., & Kokko, . H. (2014). The evolution of genomic imprinting: costs, benefits and long-term consequences. Biological Reviews, 89(3), 568-587. https://doi.org/10.1111/brv.12069

Genomic imprinting refers to a pattern of gene expression in which a specific parent's allele is either under‐expressed or completely silenced. Imprinting is an evolutionary conundrum because it appears to incur the costs of diploidy (e.g. presenting...

Crozier’s paradox revisited: maintenance of genetic recognition systems by disassortative mating (2013)
Journal Article
Holman, L., van Zweden, J. S., Linksvayer, T. A., & d’Ettorre, P. (2013). Crozier’s paradox revisited: maintenance of genetic recognition systems by disassortative mating. BMC Evolutionary Biology, 13, 211. https://doi.org/10.1186/1471-2148-13-211

Background

Organisms are predicted to behave more favourably towards relatives, and kin-biased cooperation has been found in all domains of life from bacteria to vertebrates. Cooperation based on genetic recognition cues is paradoxical because it... Read More about Crozier’s paradox revisited: maintenance of genetic recognition systems by disassortative mating.

The evolution of queen pheromones in the ant genus Lasius (2013)
Journal Article
Holman, L., Lanfear, R., & d'Ettorre, P. (2013). The evolution of queen pheromones in the ant genus Lasius. Journal of Evolutionary Biology, 26(7), 1549-1558. https://doi.org/10.1111/jeb.12162

Queen pheromones are among the most important chemical messages regulating insect societies yet they remain largely undiscovered, hindering research into interesting proximate and ultimate questions. Identifying queen pheromones in multiple species w... Read More about The evolution of queen pheromones in the ant genus Lasius.

The consequences of polyandry for population viability, extinction risk and conservation (2013)
Journal Article
Holman, L., & Kokko, H. (2013). The consequences of polyandry for population viability, extinction risk and conservation. Philosophical Transactions B: Biological Sciences, 368(1613), https://doi.org/10.1098/rstb.2012.0053

Polyandry, by elevating sexual conflict and selecting for reduced male care relative to monandry, may exacerbate the cost of sex and thereby seriously impact population fitness. On the other hand, polyandry has a number of possible population-level b... Read More about The consequences of polyandry for population viability, extinction risk and conservation.

Genetic constraints on dishonesty and caste dimorphism in an ant (2013)
Journal Article
Holman, L., Linksvayer, T. A., & d’Ettorre, P. (2013). Genetic constraints on dishonesty and caste dimorphism in an ant. American Naturalist, 181(2), 161-170. https://doi.org/10.1086/668828

The ultimate causes of honest signaling remain a subject of debate, with questions remaining over the relative importance of costs and constraints. Signal costs may make dishonesty prohibitively expensive, while genetic constraints could make it impo... Read More about Genetic constraints on dishonesty and caste dimorphism in an ant.
