"WHYAGE hypothesised that species with different types of aging would show different population dynamics. We show this to be true in animals, but not plants. Animal species with extreme senescence or extreme negative senescence can bounce back quickly from environmental disturbances (such as fire, hurricanes or disease epidemics), so avoiding population decline. Animal species with negligible senescence cannot do this. This result helps foresee how a species may respond to a disturbance, which is helpful for conservation, and lends credibility to our hypothesis that diverse aging has evolved to mitigate repeated exposures to certain environmental disturbances.
Our ability to determine these results was only possible by developing our own mathematical measures of aging, and of the resilience of species to environmental disturbances. These methods have already been recognised by other academics, leading to further collaborations using the methods to explore the evolution of aging across plant and animal species. The methods are published (see below); other results are being prepared for publication.
The work has also been disseminated through organised conference sessions, and invited talks at institutes worldwide. Completion of the work was facilitated through training courses attended by the fellow, a secondment, and research visits (see below).
