Power Analysis in Survey Design?

10 October 2018 1 7K Report

This is less of a question and more of a discussion point. I pose these questions in the context of designing biodiversity surveys for terrestrial vertebrate fauna (including volant fauna).

Is power analysis of value in fauna ecology survey designs?

Is it a priori determination of the "power" values really possible with dynamics systems that are never truly stochastic or deterministic?

Is the calculation of sample size relevant in biodiversity surveys were there are multitude of species and a multitude of life cycles?

Should survey design be more art than science?

Is it not just a case of more and varied effort = better returns?

Is not power analysis and attempt to fit the data into the analytical framework we currently have, rather than the date determining if we can apply our framework? (i.e., are we losing/ignoring information)

Please join in with thoughts and pose your own questions on this topic.
