Haplodiploidy and the evolution of eusociality : split sex ratios
(2012-02) - Journal article,
It is generally accepted that from a theoretical perspective, haplodiploidy should facilitate the evolution of eusociality. However, the "haplodiploidy hypothesis" rests on theoretical arguments that were made before recent ...
The evolution of hermaphroditism by an infectious male-derived cell lineage : an inclusive-fitness analysis
(2011-08) - Journal article,
There has been much recent interest in the role for genetic conflicts to drive the evolution of genetic systems. Here we consider the evolution of hermaphroditism in the scale insect tribe Iceryini and the suggestion that ...
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 ...
Haplodiploidy and the evolution of eusociality : split sex ratios (vol 179, pg 240, 2012)
(2012-04) - Journal article,
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 ...
Haplodiploidy and the evolution of eusociality : worker reproduction
(2013-10) - Journal article,
Hamilton’s haplodiploidy hypothesis suggests that the relatively higher relatedness of full sisters in haplodiploid populations promotes altruistic sib rearing and, consequently, the evolution of eusociality. This haplodiploidy ...
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 ...
Mating ecology explains patterns of genome elimination
(2014-12) - Journal article,
Genome elimination – whereby an individual discards chromosomes inherited from one parent, and transmits only those inherited from the other parent – is found across thousands of animal species. It is more common in ...
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 ...
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 ...
