Reproduction Costs in birds
It is a project that is expected to detect the influence of the physical wear of birds breeding in the rate of aging. We will analyze in zebra finches the rate of telomere attrition in relation to the number of times played. Telomeres are molecular structures found on chromosomes, and that are affected by oxidative stress. We take blood samples from the birds before and after the breeding season, and compare changes in telomeres between different experimental groups.
