Effects of 17α‐Ethinylestradiol on Development and Gonadal Differentiation in the Estuarine Mummichog, Fundulus heteroclitus

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT In fish, sex determination and gonadal development are controlled by various genetic and environmental factors. In this study, experiments were conducted on the estuarine mummichog (Fundulus heteroclitus) to investigate gonadal differentiation following exposure to the synthetic estrogen, 17α‐ethinylestradiol (EE2).

Prevalence and Mechanisms of Sustained Force Production in the Musculature of the Southern Alligator Lizard (Elgaria multicarinata)

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The southern alligator lizard (Elgaria multicarinata) exhibits prolonged mate‐holding behavior. This behavior maybe be underpinned by a phenomenon known as sustained force, observed in the jaw muscles of this species, in which the muscle fails to relax between subsequent contractions.

Molecular Investigations on Angiogenesis and Oxidative Stress in Roe Deer (Capreolus capreolus) Bucks' Testes Throughout the Reproductive Cycle

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Animals with seasonal reproductive cycles, as the Roe deer (Capreolus capreolus), have developed mechanisms to synchronize reproduction with the environmental cycle in order to optimize reproductive success through melatonin. Angiogenesis and oxidative stress are key processes in spermatogenesis, contributing to testicular remodeling and ...
