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

Despite tremendous progress in recent years, our understanding of the evolution of ageing
is still incomplete. A dominant paradigm maintains that ageing evolves due to the competing …

Background Real-time temperature monitoring during cold chain logistics is critical because
refrigerated foods are sensitive to temperature fluctuations. Time-temperature indicators …

The trade-off between survival and reproduction is the bedrock of the evolutionary theory of
ageing. The reproductive system regulates ageing of the soma, and removal of germ cells …

Introduction Food availability is an important environmental cue for animals for deciding how
much to invest in reproduction, and it ultimately affects population size. The importance of …

Why and how we age are 2 intertwined questions that have fascinated scientists for many
decades. However, attempts to answer these questions remain compartmentalized …

Current thinking in life‐history theory and the biology of ageing suggests that ageing rates,
and consequently life spans, evolve largely as a function of trade‐offs with reproduction …

Ecological stoichiometry is a useful theoretical framework for understanding the sources and
controls on nutrient availability that structure the composition and diversity of biotic …

Costs of migration, in terms of time, energy, and mortality risk, have a strong theoretical and
empirical foundation in the study of birds. We expect these costs to be most severe for …

Food availability modulates survival in interaction with (for example) competition, disease
and predators, but to what extent food availability in natural populations affects survival …
