As a direct response to many threats facing seriously threatened amphibian species, including habitat loss, pollution and, more recently, emerging infectious disease, ex situ captive-breeding programmes have proven valuable tools in species preservat

The world's amphibians are disappearing. More than 100 species may have already gone Extinct and thousands more are threatened with extinction. Many of the threatened species cannot be safeguarded in the wild and require ex situ management if they ar

Appropriate water quality is essential for maintaining and breeding amphibians in captivity. Aquatic systems that maintain water quality have been employed for many years in the aquaculture and aquarium industries. These techniques are now more commo

Resting and maximal heart rates (HR) in ectothermic vertebrates are generally lower than those in endotherms and vary by more than an order of magnitude interspecifically. Variation of HR transcends phylogeny and is influenced by numerous factors inc

We examined caudal anatomy in two species of prehensile-tailed lizards, Furcifer pardalis and Corucia zebrata. Although both species use their tails to grasp, each relies on a strikingly different anatomy to do so. The underlying anatomies appear to

Blood supplying the brain in vertebrates is carried primarily by the carotid vasculature. In most mammals, cerebral blood flow is supplemented by the vertebral arteries, which anastomose with the carotids at the base of the brain. In other tetrapods,

Using corrosion casting, we demonstrate and describe a new vascular system—the vertebral venous plexus—in eight snake species representing three families. The plexus consists of a network of spinal veins coursing within and around the vertebral c
