Vitellogenin, juvenile hormone, insulin signaling, and queen honey bee longevity
In most animals, longevity is achieved at the expense of fertility, but queen honey bees do not show this tradeoff. Queens are both long-lived and fertile, whereas workers, derived from the sameExpand

Non-adaptive plasticity potentiates rapid adaptive evolution of gene expression in nature
Phenotypic plasticity is the capacity for an individual genotype to produce different phenotypes in response to environmental variation. Most traits are plastic, but the degree to which plasticity isExpand

A possible non-sexual origin of mate preference: are male guppies mimicking fruit?
In most animals, the origins of mating preferences are not clear. The ‘sensory–bias’ hypothesis proposes that biases in female sensory or neural systems are important in triggering sexual selectionExpand

Familiarity leads to female mate preference for novel males in the guppy, Poecilia reticulata
Guppies are a model vertebrate for studies of sexual selection and life history evolution. None the less, there have been few investigations of the factors responsible for maintaining extremeExpand

An experimental study of inbreeding depression in a natural habitat.
Inbreeding is known to lead to decreased survival and reproduction in captive populations of animals. It is also important to know whether inbreeding has deleterious effects in natural habitats. AnExpand

Age-specific inbreeding depression and components of genetic variance in relation to the evolution of senescence.
Two major theories of the evolution of senescence (mutation accumulation and antagonistic pleiotropy) make different predictions about the relationships between age, inbreeding effects, and theExpand

Quantitative genetics of sperm precedence in Drosophila melanogaster.
To assess the genetic basis of sperm competition under conditions in which it occurs, I estimated additive, dominance, homozygous and environmental variance components, the effects of inbreeding, andExpand

A genomewide assessment of inbreeding depression: gene number, function, and mode of action.
Although the genetic basis of inbreeding depression is still being debated, most fitness effects are thought to be the result of increased homozygosity for recessive or partially recessiveExpand

Gene expression patterns associated with queen honey bee longevity
The oxidative stress theory of aging proposes that accumulation of oxidative damage is the main proximate cause of aging and that lifespan is determined by the rate at which this damage occurs. TwoExpand

Evolutionary and mechanistic theories of aging.
Senescence (aging) is defined as a decline in performance and fitness with advancing age. Senescence is a nearly universal feature of multicellular organisms, and understanding why it occurs is aExpand
