Hi,

So far, I have derived the confidence intervals for abundance from the CI's for the density, which I get with the derived function.

However, if a specific number of animals, let's say n_obs have been captured in an area, then I believe the lower limit of the confidence interval should be at least as large as n_obs, since this is the number which definetely exists in the study area (?)

However, if I derive this from the density lower CI limit, then the lower limit of the CI for abundance is lower then n_obs.

Does anyone have an opionion how to deal with this?

Thanks and best regards, Ulrike
