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 …

The extent to which the age of parents at reproduction can affect offspring lifespan and other
fitness-related traits is important in our understanding of the selective forces sha** life …

Reproductive Biology of Teleost Fishes is the first integrated review of the reproductive
biology of the bony fishes, which are the most species-rich and diversified group of …

Highlights•We examined the development of two personality traits, boldness and docility, in
yellow-bellied marmots.•Boldness was not a personality trait in juveniles, but was in …

How does an animal age in natural conditions? Given the multifaceted nature of
senescence, identifying the effects of age on physiology and behavior remains challenging …

An animal's behaviour can influence many variables, such as its energy reserves, its risk of
injury or mortality, and its rate of reproduction. To identify the optimal action in a given …

In humans, gut microbiome (GM) differences are often correlated with, and sometimes
causally implicated in, ageing. However, it is unclear how these findings translate in wild …

Many organisms defend their fitness against attack from parasites and pathogens by
mounting an immune response. Most physiological immune responses are internal and …

A plant's reproductive allocation (RA) schedule describes the fraction of surplus energy
allocated to reproduction as it increases in size. While theorists use RA schedules as the …

Declines in survival and reproduction with age are prevalent in wild vertebrates, but we
know little about longitudinal changes in behavioral, morphological, or physiological …
