Proc Biol Sci
. 2017 May;
284(1854).
PMID: 28469015
Kin selection theory predicts that animals should direct costly care where inclusive fitness gains are highest. Individuals may achieve this by directing care at closer relatives, yet evidence for such...

Proc Natl Acad Sci U S A
. 2017 Apr;
114(20):5207-5212.
PMID: 28439031
Kin selection theory predicts that, where kin discrimination is possible, animals should typically act more favorably toward closer genetic relatives and direct aggression toward less closely related individuals. Contrary to...

Ecol Evol
. 2017 Mar;
7(6):1712-1724.
PMID: 28331582
Early-life ecological conditions have major effects on survival and reproduction. Numerous studies in wild systems show fitness benefits of good quality early-life ecological conditions ("silver-spoon" effects). Recently, however, some studies...

Cooney F, Vitikainen E, Marshall H, van Rooyen W, Smith R, Cant M, et al.
R Soc Open Sci
. 2016 Dec;
3(11):160682.
PMID: 28018658
In eusocial insects, the ability to discriminate nest-mates from non-nest-mates is widespread and ensures that altruistic actions are directed towards kin and agonistic actions are directed towards non-relatives. Most tests...

Behav Ecol
. 2016 Jul;
27(4):978-987.
PMID: 27418750
Ecological conditions are expected to have an important influence on individuals' investment in cooperative care. However, the nature of their effects is unclear: both favorable and unfavorable conditions have been...

. 2016 Mar;
283(1826):20152607.
PMID: 26936245
In many vertebrate societies, forced eviction of group members is an important determinant of population structure, but little is known about what triggers eviction. Three main explanations are: (i) the...

Sci Rep
. 2016 Jan;
6:20013.
PMID: 26817515
Female intrasexual competition is intense in cooperatively breeding species where offspring compete locally for resources and helpers. In mammals, females have been proposed to adjust prenatal investment according to the...

. 2015 Dec;
186(6):716-27.
PMID: 26655979
Sex-biased dispersal and multiple mating may prevent or alleviate inbreeding and its outcome, inbreeding depression, but studies demonstrating this in the wild are scarce. Perennial ant colonies offer a unique...

Sanderson J, Wang J, Vitikainen E, Cant M, Nichols H
Mol Ecol
. 2015 Jun;
24(14):3738-51.
PMID: 26095171
Inbreeding and inbreeding avoidance are key factors in the evolution of animal societies, influencing dispersal and reproductive strategies which can affect relatedness structure and helping behaviours. In cooperative breeding systems,...

Biol Rev Camb Philos Soc
. 2015 Mar;
91(2):483-97.
PMID: 25765468
Life-history theory assumes that reproduction and lifespan are constrained by trade-offs which prevent their simultaneous increase. Recently, there has been considerable interest in the possibility that this cost of reproduction...
