Globally increasing levels of artificial light at night (ALAN) are associated with shifting rhythms of behaviour in many wild species. However, it is unclear whether changes in behavioural timing are paralleled by consistent shifts in the molecular clock and its associated physiological pathways. Inconsistent shifts between behavioural and molecula...
Evidence that telomere length (TL) and dynamics can be interpreted as proxy for ‘life stress’ experienced by individuals stems largely from correlational studies. We tested for effects of an experimental increase of workload on telomere dynamics by equipping male great tits (Parus major) with a 0.9 gram backpack for a full year. In addition, we ana...

Globally increasing levels of artificial light at night (ALAN) are associated with shifts in circadian rhythms of behaviour in many wild species. However, it is still unclear whether changes in behavioural timing are underlined by parallel shifts in the molecular clock, and whether such internal shifts may differ between different tissues and physi...
Brachytherapy-based radiotherapy has been applied for decades in the curative treatment for solitary, ≤ 5 cm bladder tumors. This review provides a historical perspective of this organ sparing approach.
A systematic search of the published literature between 1900 and 2019 was performed on the subject of bladder brachytherapy using PubMed, with dig...
Circadian rhythms are ubiquitous among taxa and are essential for coping with recurrent daily events, leading to selection on the properties of the clock underlying these rhythms. To quantify this selection in the wild, we need, however, to phenotype wild individuals, which is difficult using the standard laboratory approach for which individuals n...
Telomere length (TL) is increasingly used as a biomarker of senescence, but measuring telomeres remains a challenge. Within tissue samples, TL varies between cells and chromosomes. Class I telomeres are (presumably static) interstitial telomeric sequences, and terminal telomeres have been divided in shorter (Class II) telomeres and ultra‐long (Clas...
Telomeres are highly conserved regions of DNA that protect the ends of linear chromosomes. The loss of telomeres can signal an irreversible change to a cell's state, including cellular senescence. Senescent cells no longer divide and can damage nearby healthy cells, thus potentially placing them at the crossroads of cancer and ageing. While the epi...
A new measurement to quantify variation in quality and rate of ageing between individuals is telomere length. Telomeres are a piece of DNA at the end of chromosomes, and they protect the other DNA. In many species shortening of telomere length with increasing age was demonstrated. This shortening is accelerated by processes that also decrease life...
Iteroparous organisms face a trade-off between reproduction and survival but knowledge of whether, how and when costs of long-term increases in workload are paid is scant. We increased locomotion costs for a whole year by equipping male great tits with a backpack during breeding, removing the backpacks one year later. We applied three different tre...
Telomere length predicts survival in birds, and many stressors that presumably reduce fitness have also been linked to telomere length. The response to selection of telomere length will be largely determined by the heritability of this trait; however, little is known about the genetic component of telomere length variation in animals other than hum...
Estimating the number of genome copies in a tissue sample can serve various purposes. For example, such an estimate serves as a scaling variable when measuring telomeres with quantitative PCR. We describe the primer development and evaluation for the glyceraldehyde- 3-phosphate dehydrogenase (GAPDH) gene in the Great Tit Parus major, as a control g...
In cooperative breeders, the tension between the opposing forces of kin selection and kin competition is at its most severe. Although philopatry facilitates kin selection, it also increases the risk of inbreeding. When dispersal is limited, extra-pair paternity might be an important mechanism to avoid inbreeding, but evidence for this is equivocal....
