Table 1 Results of linear mixed models for the effects of hatch stage (early, middle and late), age (3- and 6-day-old), nest temperature on body temperature, blood thyroid hormones (triiodothyronine, T3 and thyroxine, T4) and corticosterone concentration in wild Asian Short-toed Lark (Alaudala cheleensis) nestlings captured in Hulun Lake Nature Reserve, Inner Mongolia, China

From: Endocrine response of early-hatching Asian Short-toed Lark nestlings exposed to cold temperature in a high-latitude grassland habitat
