Young parents produce offspring with short telomeres: A study in a long-lived bird, the Black-browed Albatross (Thalassarche melanophrys)
In wild vertebrates, young parents are less likely to successfully rear offspring relative to older ones because of lower parental skills ('the constraint hypothesis'), lower parental investment ('the restraint hypothesis') or because of a progressive disappearance of lower-quality individuals at young ages ('the selection hypothesis'). Because it is practically difficult to follow an offspring...
متن کاملOffspring telomere length in the long lived Alpine swift is negatively related to the age of their biological father and foster mother.
A growing body of studies is showing that offspring telomere length (TL) can be influenced by the age of their parents. Such a relationship might be explained by variation in TL at conception (gamete effect) and/or by alteration of early growth conditions in species providing parental care. In a long-lived bird with bi-parental care, the Alpine swift (Apus melba), we exchanged an uneven number ...
متن کاملTelomere dynamics may link stress exposure and ageing across generations.
Although exposure to stressors is known to increase disease susceptibility and accelerate ageing, evidence is accumulating that these effects can span more than one generation. Stressors experienced by parents have been reported to negatively influence the longevity of their offspring and even grand offspring. The mechanisms underlying these long-term, cross-generational effects are still poorl...
متن کاملMaternal and genetic factors determine early life telomere length.
In a broad range of species--including humans--it has been demonstrated that telomere length declines throughout life and that it may be involved in cell and organismal senescence. This potential link to ageing and thus to fitness has triggered recent interest in understanding how variation in telomere length is inherited and maintained. However, previous studies suffer from two main drawbacks ...
متن کاملEmbryonic and postnatal telomere length decrease with ovulation order within clutches
Telomere length (TL) in early life has been found to be predictive of subsequent lifespan. Factors such as parental TL, parental age and environmental conditions during development have been shown to contribute to the observed variation in TL among individuals. One factor that has not hitherto been considered is ovulation order, although it is well established that the last hatched/born offspri...
