Endocrine disruptors are substances that can interfere with the normal functioning of hormone regulation in an individual and thus potentially interfere with associated biological functions. But how exactly do contaminants... Learn more

Are whale protection and research work compatible?

Better understanding cetaceans to better protect them is the goal of many researchers working on these giants of the seas. However, some methods such as biopsies or tagging are intrusive and can disturb the individuals under study. Disturbing whales to better understand them, in order to subsequently disturb them less: how do we reconcile this... Learn more
