Telomere dynamics in free-living edible dormice (Glis glis): the impact of hibernation and food supply
Franz Hoelzl, Jessica S. Cornils, Steve Smith, Yoshan Moodley, Thomas Ruf
Highlighted Article: Telomeres in edible dormice shorten over the hibernation season, but these long-lived rodents are able to fully restore telomeres during summer if food supply is sufficient.
Variation in early-life telomere dynamics in a long-lived bird: links to environmental conditions and survival
Hannah Watson, Mark Bolton, Pat Monaghan
Summary: The environment strongly influences early-life telomere attrition, suggesting that telomere dynamics may underlie cohort effects often observed in natural populations and may mechanistically link early-life stress and later-life performance.

Summary: Both leptin and IGF-I are involved in the control of mink ovarian steroid hormone release. Reproductive aging can be due to (a) reduction in basal progesterone release and (b) alterations in the response of estradiol but not of progesterone to leptin and IGF-I.
