A minimally invasive procedure for blood extraction from Xenopus laevis allows follow up studies without euthanasia

Blood extraction is extremely important for the development of scientific research; however, the existing methods for amphibian´s blood sampling are invasive, mainly leading to the euthanasia of the animal. Therefore, less intrusive methods that allow the obtention of multiple samples...

Increasing the psychological wellbeing of zebrafish (Danio rerio) and African clawed frogs (Xenopus laevis) at the Cleveland Clinic

With the increased use of aquatic animals in research, especially zebrafish and African clawed frogs, there has been an increased interest in how to best address their psychological wellbeing. In this article, we have shown various ways to improve the...

Posture as a non-invasive indicator of arousal in American toads (Anaxyrus americanus)

Animal welfare has become a priority for modern zoos and aquariums. However, amphibians have not yet been the focus of much welfare research, perhaps in part because they do not tend to display many quantifiable active behaviors. This study focused...

Effects of background color on stress-linked behavior in the critically endangered Lake Oku clawed frog (Xenopus longipes)

Ex situ amphibian populations are a key component of global amphibian conservation strategy, and optimal husbandry is vital to ex situ conservation success. Animal behavior can be used to inform captive welfare and improve husbandry practices. However, it has been...

Chronic captivity stress in wild animals is highly species-specific

Wild animals are brought into captivity for many reasons—conservation, research, agriculture and the exotic pet trade. While the physical needs of animals are met in captivity, the conditions of confinement and exposure to humans can result in physiological stress. The...
