Reproductive differences between urban and forest birds across the years: importance of environmental and weather parameters
Urban environments pose many challenges to wildlife, not least for insectivorous passerines. Numerous studies have reported on the negative effects of urbanization on reproduction in these species. However, de...

Telomere dynamics in female Columbian ground squirrels: recovery after emergence and loss after reproduction
Telomeres are specialized non-coding DNA sequences located at the end of chromosomes and that protect genetic information. Telomere loss over lifespan is generally viewed as a phenomenon associated with aging ...

Contrasting associations between nestling telomere length and pre and postnatal helpers’ presence in a cooperatively breeding bird
Studies on cooperative breeders have addressed the effects of non-breeding ‘helpers’ on reproduction and parental care, but the consequences for offspring physiology and long-term survival are less understood....

Seasonal variation in telomere dynamics in African striped mice
Telomere shortening has been used as an indicator of aging and is believed to accelerate under harsh environmental conditions. This can be attributed to the fact that telomere shortening has often been regarde...

Starting with a handicap: effects of asynchronous hatching on growth rate, oxidative stress and telomere dynamics in free-living great tits
A trade-off between resource investment into growth rate and body self-maintenance is likely to occur, but the underlying molecular mediators of such a trade-off remain to be determined. In many altricial bird...

Elevation impacts the balance between growth and oxidative stress in coal tits
The short favorable period of time available for the growth in seasonal environments could constrain the resources allocation between growth and other life-history traits, and the short-term fitness benefits o...

Open AccessEffects of brood size manipulation and common origin on phenotype and telomere length in nestling collared flycatchers
Evidence is accumulating that telomere length is a good predictor of life expectancy, especially early in life, thus calling for determining the factors that affect telomere length at this stage. Here, we inve...
