Hi, yes there is a difference between creating new frameworks, and just adopting frameworks to different species in parallel. You probably have in mind the establishment of welfare biology as a new field. What happens in that case is that the study of the circumstances affecting the welfare of wild animals requires learning many things about their environment, due to which cross-disciplinary work intersecting animal welfare science and ecology is needed, which is not the case with domesticated animals.
You’re probably right with regards to sources of funding for cognitive ethology, and that’s also the case for animal welfare science.What you say about little attention being paid to invertebrates is also true.
Thanks for your comment!
