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. 
Paredes, E., Costas, D. 2020. Non-lethal sex identification of sea urchins: Method and advantages. Lab Animal 49(1), 7–8.

A simple method for sex determination can reduce the number of sea urchins used in the lab and help to optimize experimental design. Our new methodology developed with Paracentrotus lividus is simple and inexpensive, requiring...

Elwood, R. W. 2020. Do arthropods respond to noxious stimuli purely by reflex? Animal Sentience 29(10).

Mikhalevich & Powell (2020) argue that it is wrong to dismiss the idea of sentience in invertebrates. Here, I expand on the evidence for crustaceans responding to noxious stimuli in ways that are not explained...

Mather, J. A. 2019. Ethics and care: For animals, not just mammals. Animals 9(12), 1018.

Animals come in a huge array of types, species and structures, but without realizing it, we have focused our care on those like us, mammals. They look something like us, so it's easy to empathize...

Robinson, P., Trim, S., Trim, C. 2019. Non-invasive extraction of Cnidarian venom through the use of autotomised tentacles. Animal Technology and Welfare 18(3), 167-173.

The animals contained within the phylum Cnidaria (Sea Anemones, Corals, Sea Pens, Jellyfish, Boxjellies and Hydra) have origins that can be dated back to around 750 million years ago (mya) and as such, they represent...

Mather, J. A., Carere, C. 2019. Consider the individual: Personality and welfare in invertebrates. In: The Welfare of Invertebrate Animals. Carere, C., Mather, J. (eds), 229-245. Springer, Cham.

Personality, defined as consistent between-individual variation in clusters of behavioral traits independent of factors such as age or sex, emerges in most animal species tested so far. The number of invertebrate species discovered to have...

Cooke, G. M., Tonkins, B. M., Mather, J. A. 2019. Care and enrichment for captive cephalopods. In: The Welfare of Invertebrate Animals. Carere, C., Mather, J. (eds), 179-208. Springer, Cham.

Cephalopods have become an archetype for invertebrate cognition, sentience and welfare studies. Their convergence with so-called ‘higher’ vertebrates (birds, mammals) in memory, learning, problem-solving, tool use and likely sentience has made biologists completely rethink the...

Elwood, R. W. 2019. Assessing the potential for pain in crustaceans and other invertebrates. In: The Welfare of Invertebrate Animals. Carere, C., Mather, J. (eds), 147-177. Springer, Cham.

All animals face hazards that cause tissue damage, and most have nociceptive reflex responses that protect them from such damage. However, some taxa have also evolved the capacity for pain experience, presumably to enhance long-term...

Kralj-Fišer, S., Gregorič, M. 2019. Spider welfare. In: The Welfare of Invertebrate Animals. Carere, C., Mather, J. (eds), 105-122. Springer, Cham.

Spiders with around 48,000 recorded species are major terrestrial predators and thus crucially important for ecosystem functioning. They are widely used as research models and for biodiversity displays and sometimes also kept as pets. Nevertheless...

Liedtke, J., Schneider, J. M. 2017. Social makes smart: Rearing conditions affect learning and social behaviour in jumping spiders. Animal Cognition 20(6), 1093–1106.

There is a long-standing debate as to whether social or physical environmental aspects drive the evolution and development of cognitive abilities. Surprisingly few studies make use of developmental plasticity to compare the effects of these...

Schlüns, H., Welling, H., Federici, J. R. et al. 2017. The glass is not yet half empty: Agitation but not Varroa treatment causes cognitive bias in honey bees. Animal Cognition 20(2), 233–241.

Honey bees (Apis mellifera) are prone to judge an ambiguous stimulus negatively if they had been agitated through shaking which simulates a predator attack. Such a cognitive bias has been suggested to reflect an internal...

Hawkins, P. 2014. Refining housing, husbandry and care for animals used in studies involving biotelemetry. Animals 4(2), 361-373.

Biotelemetry can contribute towards reducing animal numbers and suffering in disciplines including physiology, pharmacology and behavioural research. However, the technique can also cause harm to animals, making biotelemetry a ‘refinement that needs refining’. Current welfare...
