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 mortality, onset of senescence and rate of senescence) between both sexes of free-ranging and zoo populations of more than 50 mammal species. We found that mammals from zoo populations generally lived longer than their wild counterparts (84% of species). The effect was most notable in species with a faster pace of life (i… 
The diversity of maternal-age effects upon pre-adult survival across animal species
TLDR
It is found that maternal age affects pre-adult survival in 252 of 272 populations (93%) representing 97 animal species, confirming the presence of senescence and observing that some differences appear to be consistent with predictions from evolutionary theory.
Senescence and costs of reproduction in the life history of a small precocial species
Abstract Species following a fast life history are expected to express fitness costs mainly as increased mortality, while slow‐lived species should suffer fertility costs. Because observational
Integrating Mortality Risk and the Adaptiveness of Hibernation
TLDR
It is found that longevity increased significantly with hibernation season duration, an effect that was particularly strong in small hibernators (<1.5 kg) especially for bats, and suggested that activity time budgets may be selected to reduce mortality risks according to life history pace.
The case for extended lifespan in cooperatively breeding mammals: a re-appraisal
TLDR
Data supports a causal role of subterranean living on lifespan extension in mammals and does not find any consistent, strong evidence that cooperative breeders have longer lifespans than other mammals after having controlled for variation in body mass, mode of life and data quality.
Reproductive senescence in a short-lived fish.
TLDR
A clear case of reproductive senescence is reported in a fish with a long post-maturation growth period, unusually rapid development and short lifespan, using longitudinal data on laboratory and wild-type populations.
An explanation for negligible senescence in animals
TLDR
This work provides an explanation for the appearance of negligible senescence in many wild animals and demonstrates that the underestimated aging rate for wild animals with low recovery probability can be generalizable to any aging models.
Reproductive Senescence in Two Lemur Lineages
TLDR
Investigating age-related female reproductive performance in two wild sympatric populations of Malagasy primates contributes valuable comparative information on reproductive senescence in a basal group of primates, and offers insights into the modulating effects of environmental, social and phylogenetic factors on patterns and dynamics of age-specific female reproduction.
Senescence as a trade-off between successful land colonisation and longevity: critical review and analysis of a hypothesis
TLDR
Senescence may have emerged as a side effect of the evolution of adaptive features that allowed the colonisation of land, and may be a compromise between land colonisation and longevity in mammals.
An integrative view of senescence in nature
TLDR
This special feature highlights several axes of research that would benefit from more integrative and multidisciplinary approaches, and argues that while these different research axes constitute key avenues of investigations for the coming years, they are only the tip of the iceberg.
Thermal conditions predict intraspecific variation in senescence rate in frogs and toads
TLDR
It is shown that warmer temperatures are associated with increased senescence rates and decreased lifespans in four amphibian species that are widely distributed across two continents (North America and Europe) and highlights the role of changing climatic conditions in the aging of ectotherms in the context of global warming.

Living fast and dying young: A comparative analysis of life‐history variation among mammals
TLDR
This paper compares patterns of mortality from natural populations of mammals with a variety of life histories and finds that, after removing the effects of body weight, mortality is the best predictor of variation in life-history traits.
Senescence rates are determined by ranking on the fast-slow life-history continuum.
TLDR
Without using life tables, senescence rates in annual individual fitness is examined using 20 individual-based data sets of terrestrial vertebrates with contrasting life histories and body size to assess the robustness of the prevalent life-table approach.
AGE‐SPECIFIC SURVIVAL IN FIVE POPULATIONS OF UNGULATES: EVIDENCE OF SENESCENCE
TLDR
Age- and sex-specific survival in five populations of three species of ungulates using recent statistical developments of capture-mark-recapture models and long-term data on marked individuals suggests species differences in social behavior may be more important than simply the level of polygyny in explaining sexual differences in survival.
Do age‐specific survival patterns of wild boar fit current evolutionary theories of senescence?
TLDR
The study indicates that the timing of senescence, not the rate, is associated with the magnitude of fertility in ungulates, demonstrating the importance of including the timing in addition to its rate to understand variation in senescences patterns in wild populations.
Age at the onset of senescence in birds and mammals is predicted by early-life performance
TLDR
From a comparative analysis based on 81 free-ranging populations of 72 species of birds and mammals, it is found that a nonlinear combination of fecundity, age at first reproduction and survival over the immature stage can account for ca two-thirds of the variance in the age at the onset of actuarial senescence.
A comparative assessment of univariate longevity measures using zoological animal records
TLDR
Mean adult lifespan and quantile‐based measures, and in particular the 90th quantile of longevity, performed particularly well, demonstrating far less sensitivity to small sample size effects than MRLS while preserving much of the information contained in the maximum lifespan measure.
Assessing senescence patterns in populations of large mammals
TLDR
A first analysis of the suitability of the Gompertz and the two-parameter Weibull models for describing aging–related mortality in free–ranging populations of ungulates and a comparative analysis of senescence patterns in both sexes of two ungulate species highly contrasted according to the intensity of sexual selection are proposed.
Longevity in Bovids Is Promoted by Sociality, But Reduced by Sexual Selection
TLDR
The results show that longevity increases with sociality in both sexes and decreases with male-biased sexual size-dimorphism, but in males only, and suggest that sociality, a key ungulate strategy to reduce predation-related mortality, selects for inherently longer-lived organisms.
Mating system, feeding type and ex situ conservation effort determine life expectancy in captive ruminants
TLDR
The method facilitates the identification of biological characteristics of species that are relevant for their husbandry success, and they also support ecological theory, which can help to improve animal husbandry.
