Female preferences for timing in a fiddler crab with synchronous courtship waving displays (2014)
Journal Article
Kahn, A. T., Holman, A., & Backwell, P. R. (2014). Female preferences for timing in a fiddler crab with synchronous courtship waving displays. Animal Behaviour, 98, 35-39. https://doi.org/10.1016/j.anbehav.2014.09.028

Studies of sexual communication typically focus on the design and information content of a signal of interest, but the timing of signal production relative to nearby competitors can be crucial. Male fiddler crabs, Uca mjoebergi, court females with a... Read More about Female preferences for timing in a fiddler crab with synchronous courtship waving displays.

Even more functions of sperm RNA: a response to Hosken and Hodgson (2014)
Journal Article
Holman, L., & Price, T. A. (2014). Even more functions of sperm RNA: a response to Hosken and Hodgson. Trends in Ecology and Evolution, 29(12), 648-649. https://doi.org/10.1016/j.tree.2014.09.014

As recently outlined in TREE [1], many animals and plants are thought to load their male gametes with multiple types of RNA, some of which enters the oocyte upon fertilization. Four classes of ultimate hypotheses for sperm RNA were proposed [1], addi... Read More about Even more functions of sperm RNA: a response to Hosken and Hodgson.

Bumblebee size polymorphism and worker response to queen pheromone (2014)
Journal Article
Holman, L. (2014). Bumblebee size polymorphism and worker response to queen pheromone. PeerJ, 2, Article e604. https://doi.org/10.7717/peerj.604

Queen pheromones are chemical signals produced by reproductive individuals in social insect colonies. In many species they are key to the maintenance of reproductive division of labor, with workers beginning to reproduce individually once the queen p...

Local Adaptation and the Evolution of Female Choice (2014)
Book Chapter
Holman, L., & Kokko, H. (2014). Local Adaptation and the Evolution of Female Choice. In J. Hunt, & D. J. Hosken (Eds.), Genotype‐by‐Environment Interactions and Sexual Selection. Chichester: Wiley. https://doi.org/10.1002/9781118912591.ch3

The evolution of mate choice remains controversial, particularly when the choosy sex receives nothing but genes from their mates. Indirect benefits are predicted to be meagre because persistent female choice depletes genetic variation in the male tra... Read More about Local Adaptation and the Evolution of Female Choice.

Cuticular lipids correlate with age and insemination status in queen honeybees (2014)
Journal Article
Babis, M., Holman, L., Fenske, R., Thomas, M., & Baer, B. (2014). Cuticular lipids correlate with age and insemination status in queen honeybees. Insectes Sociaux, 61, 337-345. https://doi.org/10.1007/s00040-014-0358-2

Eusocial insects exhibit reproductive division of labour, in which one or a few queens perform almost all of the reproduction, while the workers are largely sterile and assist in rearing their siblings. Consequently, many of the colony’s tasks (e.g.... Read More about Cuticular lipids correlate with age and insemination status in queen honeybees.

Polyandrous females found fitter populations (2014)
Journal Article
Power, D. J., & Holman, L. (2014). Polyandrous females found fitter populations. Journal of Evolutionary Biology, 27(9), 1948-1955. https://doi.org/10.1111/jeb.12448

Multiple mating by females (polyandry) requires an evolutionary explanation, because it carries fitness costs in many species. When mated females disperse alone to a new habitat, their offspring may have no option but to mate with their siblings and... Read More about Polyandrous females found fitter populations.

Conditional helping and evolutionary transitions to eusociality and cooperative breeding (2014)
Journal Article
Holman, L. (2014). Conditional helping and evolutionary transitions to eusociality and cooperative breeding. Behavioral Ecology, 25(5), 1173-1182. https://doi.org/10.1093/beheco/aru100

The nonreproductive helpers of many arthropod, bird and mammal species are a perennial puzzle for evolutionary biologists. Theory and evidence suggests that helping is favored by high relatedness between social partners and by certain ecological fact...

Conserved class of queen pheromones stops social insect workers from reproducing (2014)
Journal Article
Van Oystaeyen, A., Caliari Oliveira, R., Holman, L., van Zweden, J. S., Romero, C., Oi, C. A., …Wenseleers, T. (2014). Conserved class of queen pheromones stops social insect workers from reproducing. Science, 343(6168), 287-290. https://doi.org/10.1126

A major evolutionary transition to eusociality with reproductive division of labor between queens and workers has arisen independently at least 10 times in the ants, bees, and wasps. Pheromones produced by queens are thought to play a key role in reg... Read More about Conserved class of queen pheromones stops social insect workers from reproducing.

Fiddlers on the roof: elevation muddles mate choice in fiddler crabs (2014)
Journal Article
Holman, L., Kahn, A. T., & Backwell, P. R. (2014). Fiddlers on the roof: elevation muddles mate choice in fiddler crabs. Behavioral Ecology, 25(2), 271-275. https://doi.org/10.1093/beheco/art125

Biological signaling usually occurs in complex environments, yet signals are most often studied in controlled experiments that strip away this complexity. Male fiddler crabs possess one enlarged claw that is waved during courtship displays, and femal... Read More about Fiddlers on the roof: elevation muddles mate choice in fiddler crabs.
