Scientific research and analysis

We revise scientific publications and advise on the scientific strength of campaigns, as well as designing scientific projects and analyzing scientific data. We also do general journalistic research, and give expert testimonies.


Our experience in this subject comes from our scientific background in biology/zoology, including the publication of several peer reviewed scientific papers on animal behaviour, and the production of scientific reports and articles on investigations of zoos, pet shops, aquaria and bullfighting.
