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 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 …

Vital rates of large herbivores normally respond to increased resource limitation by following
a progressive sequence of effects on life‐history characteristics from survival of young, age …

Explaining variation in life expectancy between individuals of the same age is fundamental
to our understanding of population ecology and life history evolution. Variation in the length …

Growth is a fundamental biological process, driven by a multitude of intrinsic (within‐
individual) and extrinsic (environmental) factors, that underpins individual fitness and …

A major question in ecology is how age-specific variation in demographic parameters
influences population dynamics. Based on long-term studies of growing populations of birds …

Senescence—the decline in age‐specific contribution to fitness with increasing age—has
been widely investigated in evolutionary ecology. A tremendous amount of detailed …

The degree to which changes in lifespan are coupled to changes in senescence in different
physiological systems and phenotypic traits is a central question in biogerontology. It is …

Telomere length (TL) is considered an important biomarker of whole-organism health and
aging. Across humans and other vertebrates, short telomeres are associated with increased …

Mule deer and black‐tailed deer O docoileus hemionus have exhibited marked population
fluctuations throughout their range over the past century. The relative contributions of …
