1. Species richness is a state variable of some interest in monitoring programmes but raw species counts are often biased due to imperfect species detectability. Therefore, monitoring programmes ...

In animal surveys, detectability can vary widely across species. We hypothesized that detectability of animals should be a function of species traits such as mass, color, and mean herd size. We also ...

Risk management involves a three-step procedure: hazard identification, risk assessment, and risk mitigation in case of unacceptable risk levels. In fact, the hazard identification process should ...
