Ex situ amphibian nutrition: recent findings and future directions

In 2013 a workshop was hosted to evaluate the current understanding of amphibian medicine and nutrition, in order to further our progress in establishment of successful breeding programs to promote amphibian conservation (Olea-Popelka et al., 2014). The Nutrition Working Group identified a number of challenges and opportunities for advancement in this field (Ferrie et al., 2014). First, an overarching theme...

Nutritional diseases of amphibians

Basic knowledge of amphibian nutrition lags far behind that of reptiles and even fish. Recent documentation of worldwide declines and extinctions of amphibian populations and subsequent development of a variety of ex-situ and in-situ captive propagation programs will almost certainly increase the demand for scientifically based programs for nutritional management of these animals. Because the class Amphibia has such rich...

Vitamin D and Primates: Recurring Problems on a Familiar Theme

Captive primates housed indoors with little access to ultraviolet light have historically been susceptible to metabolic bone disease. The trend in zoological parks toward building large, indoor exhibits has potentially exacerbated this problem. Most skylight materials are not transparent to the wavelengths of ultraviolet light (UV-B) necessary for endogenous production of vitamin D. It is possible that most primates, like...
