Ageing Studies on Bats: A Review

  title={Ageing Studies on Bats: A Review},
  author={Anja K. Brunet-Rossinni and Steven N. Austad},
Bat biologists have long known about the exceptional longevity of bats (Order: Chiroptera), which is unusual for mammals of such a small size and a high metabolic rate. Yet relatively few mechanistic studies have focused on this longevity. On average, species of Chiroptera live three times longer than predicted by their body size. In addition, bats have other life history traits that are characteristic of large, long-lived mammals such as few and large offspring and slow growth rates. Bats fit… 

Bats and birds: Exceptional longevity despite high metabolic rates

Methods for Age Estimation and the Study of Senescence in Bats

This chapter describes techniques for age determination and discusses senes-cence and longevity in bats, and presents methods currently available for the determination of age in juvenile and adult bats, highlight the advantages and disadvantages of each, and provide guidelines to use when selecting a method.

Rare catastrophic events drive population dynamics in a bat species with negligible senescence

Using a large set of individual-based data collected over 19 years in four free-ranging colonies of Bechstein’s bats (Myotis bechsteinii), there is no increase in the rate of mortality and no decrease in fertility demonstrating no senescence until high ages.

Striking longevity in a hibernating lemur

D dwarf lemurs live significantly longer, reproduce longer and show later incidences of both morphologic and reproductive senescence than the other species analyzed, indicating that intrinsic biologic effects must play some role in captive populations with no predation.

Taking flight: An ecological, evolutionary and genomic perspective on bat telomeres

The current knowledge on bat telomeres, telomerase expression, and how these relate to ecology, longevity and life‐history strategies are detailed, including how new high quality, chromosome‐level genome assemblies can enable us to uncover the molecular mechanisms governing telomere dynamics.

Sex-Biased Senescence in a Polygynous Bat Species

The results are consistent with the theories for polygynous mammals, which view the trade-off between male investment in physical traits for intense male–male competition against survival as a major source of the decline of male survival with age.

Mechanisms of aging in the naked mole-rat: The case for programmed aging

This premise that maximum species lifespan is indeed encoded in the genome is explored by reevaluating the various theories of aging in the light of what is known from the biology of the longest-living rodent, the naked mole-rat.



Life history, ecology and longevity in bats

It is speculated that hibernation may provide a natural example of caloric restriction, which is known to increase longevity in other mammals, and the strong association between life span and both reproductive rate and hibernation suggests that bat longevity is strongly influenced by seasonal allocation of non‐renewable resources to reproduction.

Mammalian aging, metabolism, and ecology: evidence from the bats and marsupials.

Bats have maximum life spans a minimum of 3 times those of nonflying eutherians--a trend resulting from neither low basal metabolic rate, the ability to enter torpor, nor large relative brain size, consistent with an evolutionary theory that posits exceptionally long life spans among mammals with reduced environmental vulnerability.

Constraints on Reproduction by Flying Vertebrates: Energy and Calcium

It is shown that bats invest more per young than do other mammals and hypothesize that this results from a fundamental, proximate constraint acting on flying vertebrates in general that restricts the number of offspring they can raise at one time.

Living fast and dying young: A comparative analysis of life‐history variation among mammals

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.

Life history differences among the eutherian radiations

It is suggested that eutherian life histories are better thought of as adaptive strategies, and that mortality patterns offer considerably more promise in the understanding of e Lutherian life history diversity than loosely defined ideas about scaling principles and the allometric consequences of body size.

Bat life histories:: Testing models of mammalian life-history evolution

It is proposed that bats decouple the age at which sexual maturity is reached from theAge at which adult size is reached, because of the constraints of flight, which violates one of the assumptions not only of Charnov's model, but also of the more general model of Kozlowski and Weiner.

Earlier Breeding Shortens Life in Female Greater Horseshoe Bats

During rapid population recovery after a climate-induced crash, earlier breeding was enhanced and may be advantageous until the population stabilizes, and studies testing life history theory should take account of population trends and climate.
