Assessing metabolic rate and post‐tagging recovery in juvenile fish Juvenile fish play a crucial role in the health of aquatic ecosystems, serving both as the foundation for future adult populations and as a valuable food source. Studying the juvenile life stage of f...

At work, we often anaesthetise, perform surgery on, and tag juvenile fish. We wanted to find out if these procedures impact their oxygen consumption in the following days. Good news, we didn't find cause for concern! πŸ™‚

Something that I think doesn’t get examined enough is the tendency for technological creep to lead to a reductionist view of ecology where emergent forms and patterns are increasingly reduced to physics and de-contextualized, generalizable theories

Why don't we use behavioural ecotoxicological studies in environmental management? Michael Bertram & colleagues assess whether behavioral measures are relevant at the population level. They conclude that, yes, they are and they are underutilised. doi.org/10.1021/acs....
