Influence of Diet on Growth and Health of Captive Hatchling Gopher Tortoises (Gopherus polyphemus)
… tortoises has traditionally been associated with potential health risks, however empirical evidence in the literature is lacking. In captivity, growth rates of tortoises are generally expected to exceed those of natural populations and the main cause is probably due to differences in diet. In the …
