> Using a comprehensive dataset spanning nearly 20 years and encompassing more than 400 ex situ vertebrate populations, we applied Bayesian hierarchical modeling to quantify changes in seven population metrics over time. Instead of the general declines expected for small and often closed populations like those in zoos and aquariums, we found no change in the demographic and genetic characteristics of the majority of these populations.
