The pace-of-life syndrome (POLS) hypothesis specifies that closely related species or
populations experiencing different ecological conditions should differ in a suite of metabolic …

That senescence is rarely, if ever, observed in natural populations is an oft-quoted fallacy
within bio-gerontology. We identify the roots of this fallacy in the otherwise seminal works of …

Evolution drives, and is driven by, demography. A genotype moulds its phenotype's age
patterns of mortality and fertility in an environment; these two patterns in turn determine the …

Empirical evidence for declines in fitness components (survival and reproductive
performance) with age has recently accumulated in wild populations, highlighting that the …

Many important questions in ecology and evolutionary biology can only be answered with
data that extend over several decades and answering a substantial proportion of questions …

Research programmes on oxidative stress and hormesis are wide ranging. Biomedical and
toxicological sciences have traditionally centralised such research, but in the last years we …

Is senescence inevitable and universal for all living organisms, as evolutionary theories
predict? Although evidence generally supports this hypothesis, it has been proposed that …

Is it possible to slow the rate of ageing, or do biological constraints limit its plasticity? We test
the 'invariant rate of ageing'hypothesis, which posits that the rate of ageing is relatively fixed …

The idea that resources are limited and animals can maximise fitness by trading costly
activities off against one another forms the basis of life-history theory. Although investment in …

While it is commonly believed that animals live longer in zoos than in the wild, this
assumption has rarely been tested. We compared four survival metrics (longevity, baseline …
