The effect of nutritional stress and life history on the rate of telomere loss in black-legged kittiwake and red-legged kittiwake chicks

Slow-track species such as the red-legged kittiwake (Rissa brevirostris) and fast-track species such as the black-legged kittiwake (R. tridactyla) respond differently to environmental pressures. We examined how nutritional stress may affect the rate of telomere loss, a proxy for life expectancy, in...

We examined how nutritional stress may affect the rate of telomere loss, a proxy for life expectancy, in these two seabirds. We did not find a significant effect of nutrition on telomere dynamics.
