Putting the evidence into evidence-based husbandry: A scoping review of empirical approaches to improving captive reptile welfare

Non-avian reptiles are commonly kept in captivity, including zoos, aquariums, farms, laboratories, classrooms, rehabilitation centres, and homes. With this wide range of captive conditions and potential diversity of species housed, it is crucial to ensure that these animals are housed...

Effect of different infrared basking lamps on the heating effectiveness and desiccation of gelatine models: Implications for zoo animal husbandry

Artificial heating via lamp technology is a key feature of the husbandry of many captive animals, especially ectotherms. Short wave infrared (IRA) is theoretically more efficient in raising animal core temperature than medium (IRB) and long wave infrared (IRC) as...

Behavioral Biology of Laboratory Animals

This 30-chapter volume informs students and professionals about the behavioral biology of animals commonly housed in laboratory and other captive settings. Each species evolved under specific environmental conditions, resulting in unique behavioral patterns, many of which are maintained in captivity...

Analgesic efficacy of hydromorphone in American alligators (Alligator mississippiensis) (2025)

Background American alligators (Alligator mississippiensis) are maintained in zoos, aquaria, and farms for educational, research, and production purposes. The standard of veterinary medical care and welfare for captive reptiles requires managing pain and discomfort under conditions deemed painful in mammals....

Sedation and general anaesthesia of crocodilians: A systematic review

Sedation and general anaesthesia of crocodilians pose unique challenges due to their aggressive nature, poikilothermic physiology, and specific anatomical and physiological characteristics, all factors that complicate crocodilian anaesthesia. This review aimed to systematically review the literature regarding sedation and general...

Social structure and habitat design affect the impact of a novel feeding enrichment for alligators

Providing enrichment that expands the range of behavioral opportunities associated with food acquisition and environmental exploration is an important contributing factor to the well-being of zoo animals. These behaviors can be difficult to promote in carnivores, given their foraging strategies...

Social behavior deficiencies in captive American alligators (Alligator mississippiensis)

Understanding how the behavior of captive American alligator (Alligator mississippiensis) congregations compares to wild congregations is essential to assessing the welfare of alligators in captivity. Wild alligator congregations perform complex social behaviors, but it is unknown if such behaviors occur...

Play behavior in crocodilians

Play behavior in crocodilians is not uncommon, but it remains virtually undescribed in scientific literature. I present the first overview of play behavior of three types (locomotor play, object play and social play) in crocodilians based on original observations, published...

Welfare of farmed crocodilians: Identification of potential animal-based measures using elicitation of expert opinion

Animal-based measures are the measure of choice in animal welfare assessment protocols as they can often be applied completely independently to the housing or production system employed. Although there has been a small body of work on potential animal-based measures...
