Reaction to Novel Objects and Fecal Glucocorticoid Metabolite Levels in Two Species of Nocturnal Geckos
Many reptiles are maintained in captivity and heavily traded, although welfare measures for many species are not well established and are under-researched compared to other animals. In this study, we focused on two of these species: crested geckos (Correlophus ciliatus) and leopard geckos (Eublepharis macularius). To better interpret their behavior in captivity, the individual reaction […]
Environmental enrichment for reptiles in European zoos: Current status and perspectives
Zoos and aquaria are paying increasing attention to environmental enrichment, which has proven an effective tool for the improvement of animal welfare. However, several ongoing issues have hampered progress in environmental enrichment research. Foremost among these is the taxonomic bias, which hinders our understanding of the value of enrichment for neglected groups, such as reptiles. […]
The Effect of environmental enrichment on Salvator merianae (Squamata: Teiidae) under captivity conditions
Environmental enrichment seeks to improve the quality of care for animals in captivity through the constant generation of new sources of stimuli to simulate a complexand changing environment. Salvator merianae is a species of large lizard whose native distribution covers the subtropical and humid zones of southeastern South America. The study was carried out in […]
The importance of enrichment for advancing amphibian welfare and conservation goals
Enrichment, broadly the provision of stimuli to improve the welfare of captive animals, is known to be important in husbandry practice and in the success of ex situ conservation and reintroduction programs. Practical evidence of the importance of enrichment exists for a number of taxa, yet amphibians are poorly represented. There is no reason to […]
Stress, anxiety, fear and frustration in different reptile species: how to reduce these negative emotional states during veterinary procedures
Behavioural responses vary significantly within the Reptile Class when stressed, fearful or frustrated, making it very difficult to observe or measure their emotional state. Reptiles are not commonly seen in general veterinary practice which can mean that suitable accommodation is not always available, and as there is a huge variation in a reptile’s ability, or […]
The effect of cage size on stress levels in captive green anole (Anolis carolinensis)
Reptiles are often used as model species in scientific research and are popular in the pet trade, yet how they cope with captive conditions has not been well studied. Stress caused by captivity could affect the endocrinology, physiology and behaviour of animals, resulting in a general decrease in welfare and could confound the results of […]
A Review of Welfare Assessment Methods in Reptiles, and Preliminary Application of the Welfare Quality registered trademark Protocol to the Pygmy Blue-Tongue Skink, Tiliqua adelaidensis, Using Animal-Based Measures
Reptiles are held at wildlife parks and zoos for display and conservation breeding programs and are increasingly being kept as pets. Reliable indicators of welfare for reptiles need to be identified. Current guidelines for the captive management of reptiles utilize resource-based, rather than animal-based indicators; the latter being a more direct reflection of affective state. […]
Evaluation of Enrichment for Reptiles in Zoos
Studies on environmental enrichment for reptiles are lacking in the scientific literature. Although the literature reflects a limited take on reptile enrichment in the zoological community, it may not be the case in reality as enrichment is generally considered an important aspect of the care of nonhuman animals in captivity. This project investigated the current […]
Comparative neuroendocrinology: A call for more study of reptiles!
Body temperature and thermoregulation of Komodo dragons in the field
Komodo dragons from hatchlings (≈0.1 kg) to adults (≤80 kg) express the full magnitude of varanid species size distributions. We found that all size groups of dragons regulated a similar preferred body temperature by exploiting a heterogeneous thermal environment within savanna, forest and mangrove habitats. All dragons studied, regardless of size, were able to regulate […]
