Current Status: The Socorro isopod is listed as a federal endangered species (Federal Register 1994). In August 1988, T. thermophilum was extirpated in the wild when diminished discharge of the… Expand
Why do we age?
The evolutionary theory of ageing explains why ageing occurs and helps to clarify how the genome shapes the ageing process, thereby aiding the study of the genetic factors that influence longevity and age-associated diseases. Expand

It is argued that - with the fallacy that wild animals do not senesce finally dead and buried - collaborations between bio-gerontologists and field biologists can begin to test the ecological generality of purportedly 'public' mechanisms regulating aging in laboratory models. Expand
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. Expand
Genetic analysis of ageing: role of oxidative damage and environmental stresses
The goal here is to seek evidence for common mechanisms among diverse organisms amenable to genetic analysis and oxidative damage is a candidate for such a public mechanism of ageing. Expand
When Should Animals Tolerate Inbreeding?
The model suggests that for most mating systems, the sole factor determining whether inbreeding tolerance spreads is the cost of inbreeding avoidance, and that most forms of polygyny do not increase the payoff to inbreeding. Expand
Comparative biology of mammalian telomeres: hypotheses on ancestral states and the roles of telomeres in longevity determination
Observations support a role for human‐like telomeres in allowing longer lifespans to evolve, demonstrate the need to include telomere length in the analysis of comparative studies of oxidative protection in the biology of aging, and identify which mammals can be used as appropriate model organisms for the study of the role of telomees in human cancer and aging. Expand
Comparative biology of aging in birds: an update
Recent research in the lab and others supports the hypothesis that birds have special adaptations for preventing age-related tissue damage caused by reactive oxygen species and advanced glycosylation endproducts, or AGEs, as well as an unusual capacity for neurogeneration in brain. Expand
