Ecology drives intragenomic conflict over menopause
(2014-02) - Journal item
Menopause is the transition from reproductive to non-reproductive life well before natural death. Rather than involving a smooth, rapid change, it is normally preceded by a long period of erratic hormonal fluctuation that ...
The strategic revolution

Intragroup and intragenomic conflict over chemical defense against predators
(2018-03) - Journal article
Insects are often chemically-defended against predators. There is considerable evidence for a group-beneficial element to their defences, and an associated potential for individuals to curtail their own investment in costly ...
Simultaneous failure of two sex-allocation invariants : implications for sex-ratio variation within and between populations
(2015-07) - Journal article
Local mate competition (LMC) occurs when male relatives compete for mating opportunities, and may favour the evolution of female-biased sex allocation. LMC theory is among the most well-developed and empirically-supported ...
Mother and offspring in conflict : why not?

Dynamics of sex ratio and female unmatedness under haplodiploidy
(2014-05) - Journal article
Haplodiploid sex determination allows unmated females to produce sons. Consequently, a scarcity of males may lead to a significant proportion of females remaining unmated, which may in turn give rise to a surfeit of males ...

The first American Naturalist appeared in March 1867. In a countdown to the 150th anniversary, the editors have solicited short commentaries on articles from the past that deserve a second look.
Haplodiploidy and the evolution of eusociality : worker revolution
(2014-09) - Journal article
Hamilton suggested that inflated relatedness between sisters promotes the evolution of eusociality in haplodiploid populations. Trivers and Hare observed that for this to occur, workers have to direct helping preferentially ...
Misconceptions on the application of biological market theory to the mycorrhizal symbiosis
(2016-05-04) - Journal item
Haplodiploidy, Sex-Ratio Adjustment, and Eusociality
(2013-03) - Journal article
Hamilton's "haplodiploidy hypothesis" holds that inflated sororal relatedness has promoted altruistic sib rearing in haplodiploids, potentially explaining their apparent predisposition to eusociality. Here, we suggest that ...
