Puberty and Oestral Cycle Length in Captive Female Jaguars Panthera onca. [PDF]
Conservation Physiology, 2020 Abstract Habitat loss and fragmentation have been leading jaguars to constant conflicts with humans, and as a result, jaguar populations have been declining over the last decades. Captive breeding is often a tool for species conservation, and it is not different for jaguars.

Steroids, 2010 Both peripheral innervation and nitric oxide (NO) participate in ovarian steroidogenesis. The aims of the work were (1) to investigate whether ganglionic noradrenergic (NE) and cholinergic (Ach) stimulus modify the ovarian steroids and NO release and (2) to examine the effect of those stimuli on the mRNA expression of 3beta-HSD and P450 aromatase in ...
