So, these extreme alternatives could only be differentiated of at least one by-catch taxon was reported for the sampling event. However, this feels somewhat dis-satisfying to me, because it's still not possible to tell the difference between "none of the target taxa were detected and just a single organism of any taxon was detected", and "lots of different non-target taxa were detected, but we only bothered to report one of them".</div><div> Reports of by-catch (which I'd generically call "presence-only data") is just massively limited in its interpretability.</div><div><br></div><div><br></div><div> So, anyway, those are my answers to your questions.
