Animal response to stressors such as harsh environmental conditions and demanding
biological processes requires energy generated through increased mitochondrial activity …

Following the discoveries of telomeres and of their implications in terms of health and
ageing, there has been a growing interest into the study of telomere dynamics in wild …

Human activity is changing climatic conditions at an unprecedented rate. The impact of
these changes may be especially acute on ectotherms since they have limited capacities to …

Why and how we age are 2 intertwined questions that have fascinated scientists for many
decades. However, attempts to answer these questions remain compartmentalized …

The prediction that telomere length (TL) shortens with increasing age is a major element in
considering the role of telomeres as a key player in evolution. While telomere attrition is …

Torpor and hibernation are powerful strategies enabling animals to survive periods of low
resource availability. The state of torpor results from an active and drastic reduction of an …

Stress exposure can leave long-term footprints within the organism, like in telomeres (TLs),
protective chromosome caps that shorten during cell replication and following exposure to …

Hibernation is linked with various hypotheses to explain the extended lifespan of hibernating
mammals compared with their non-hibernating counterparts. Studies on telomeres, markers …

Increased winter survival by reducing energy expenditure in adult animals is often viewed as
the primary function of torpor. However, torpor has many other functions that ultimately …

Various biological attributes associated with individual fitness in animals change predictably
over the lifespan of an organism. Therefore, the study of animal ecology and the work of …
