Towards more compassionate wildlife research through the 3Rs principles: moving from invasive to non-invasive methods
Research in ecology and wildlife biology remains crucial for increasing our knowledge and improving species management and conservation in the midst of the current biodiversity crisis. However, obtaining information on population status often involves invasive sampling of a certain number of individual animals. Marking and sampling practices include taking blood and tissue samples, toe-clipping of […]
The interplay between replacement, reduction and refinement: considerations where the Three Rs interact
Russell and Burch’s Three Rs principle of replacement, reduction and refinement offers a useful concept for the scientific and ethical evaluation of the use of animals in scientific procedures. Replacement, reduction and refinement are often considered separately, but when applied, one of the Three Rs may have a positive or negative effect on one or […]
An illustration that statistical design mitigates environmental variation and ensures unambiguous study conclusions
This paper highlights the essential need for appropriate statistical design and randomisation in laboratory animal studies. Using an example of a 21 day weight gain study in mice, we show that without the use of an appropriate statistical design and randomisation, incorrect conclusions may have been drawn. We used an experimental design that allowed comparisons […]
ANIMAL WELFARE FROM MOUSE TO MOOSE-IMPLEMENTING THE PRINCIPLES OF THE 3RS IN WILDLIFE RESEARCH
The concept of the 3Rs (replacement, reduction, and refinement) was originally developed for improving laboratory animal welfare and is well known in biomedical and toxicologic research. The 3Rs have so far gained little attention in wildlife research, and there could be several reasons for this. First, researchers may prioritize the welfare of populations and ecosystems […]
