Refinement Database

Database on Refinement of Housing, Husbandry, Care, and Use of Animals in Research

This database, created in 2000, is updated every four months with newly published scientific articles, books, and other publications related to improving or safeguarding the welfare of animals used in research.

Tips for using the database:

  • This landing page displays all of the publications in the database.
  • Use the drop-down menus to filter these publications by Animal Type, Setting, and/or Topic.
  • Clicking on a parent category (e.g., Rodent) will include publications relating to all the items in that category (e.g., Chinchilla, Gerbil, Guinea Pig, etc.).
  • You may also add a keyword to further narrow your search.
  • Please note that at this time, only publications dated 2010 or later (with some exceptions) can be filtered by Animal Type and Topic, and only publications dated 2020 or later (with some exceptions) can be filtered by Setting. Most publications older than 2010 can only be searched by keyword.

Although the private keeping of reptiles has boomed in most western countries since the millennium, studies dealing with the recognition and promotion of welfare in these reptiles seem to represent a blind spot of scientific...

Lambert, H., Elwin, A., D’Cruze, N. 2022. Frog in the well: A review of the scientific literature for evidence of amphibian sentience. Applied Animal Behaviour Science 247, 105559.

Millions of amphibians are traded annually around the world for the exotic pet industry. Their experience during both trade, and in captivity as pets, leads to numerous animal welfare issues. The poor welfare of many...

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...

Jewell, D., Muensch, A., Kupronis, R. et al. 2021. Husbandry techniques for a research colony of veiled chameleons (Chamaeleo calyptratus). Laboratory Animal Science Professional 9(4) (July/August), 52-55.

Although most chameleon species can be challenging captives, C. calyptratus have been successfully kept and bred in captivity for over thirty years. Despite their relative familiarity, our challenge is to replicate their preferred habitats in...

Borgmans, G., Palme, R., Sannen, A. et al. 2021. Routine handling does not lead to chronic stress in captive green anole (Anolis carolinensis). Animal Welfare 30(2), 145-154.

Routine handling has been shown to affect stress levels in a variety of animal species. This could result in a general decrease in welfare and may confound the results of scientific experiments or observations on...

Petrović, T. G., Vučić, T. Z., Nikolić, S. Z. et al. 2020. The effect of shelter on oxidative stress and aggressive behavior in crested newt larvae (Triturus spp.). Animals 10(4), 603.

Shelters are important for animal survival. Provision of adequate hiding places allow animals to express their natural sheltering behavior and it can have different positive effects on cortisol levels, physiological processes and mental performance. Although...

Rasys, A. M., Divers, S. J., Lauderdale, J. D. et al. 2020. A systematic study of injectable anesthetic agents in the brown anole lizard (Anolis sagrei). Laboratory Animals 54(3), 281–292.

Anolis lizards have served as important research models in fields ranging from evolution and ecology to physiology and biomechanics. However, anoles are also emerging as important models for studies of embryo development and tissue regeneration...

Hosking, A., Martinic, G. 2020. The care of Central and Pygmy bearded dragons. Animal Technology and Welfare 19(2), 125-130.

This article describes the care of central bearded dragons (Pogona vitticeps) as well as Pygmy bearded dragons (Pogona henrylawsoni). It includes information on housing, feeding, handling and sexing technique, as well as the general health...
