Thyroid hormone manipulation influences development of endothermy and hatching in white leghorn chickens (Gallus gallus)

Data collected on metabolic rates, body temperatures, morphology, plasma T3, and hatching of developing chicken embryos and hatchlings. To understand the role thyroid hormones play in hatch timing and development of thermogenic capacity and metabolic rate plasma thyroid hormone levels were manipulated in chicken embryos beginning at 80% development (day 17 of a 21-day incubation) with either a single dose of triiodo-L-thyronine (T3) or the thyroperoxidase inhibitor methimazole (MMI).

Development of Facultative Air Breathing in Bristlenose Plecos (Ancistrus cirrhosus)

Data collected on air breathing development in the bristlenose pleco. Bristlenose plecos breath air with a highly vascularized stomach when exposed to aquatic hypoxic conditions. This study looked at the development of this behavior and when the fish fist began to breathe air.
