Estimating impacts of poison operations using mark-recapture analysis and population viability analysis: an example with New Zealand robins (Petroica australis)
... Being able to estimate detection rates offers many additional benefits. For any project, it is useful for researchers to be able to confirm that detection rates are as high as they believe them to be. More importantly, ...
