Detectability, threatened species and environmental impact assessments

This blog post is about an upcoming paper in Conservation Biology. It is now widely accepted that many species are not perfectly detectable during an ecological survey. This means that, sometimes, a species that is present at a site will not be detected by an observer (or observers) during a survey of that site. The… Continue reading Detectability, threatened species and environmental impact assessments

Data, data, everywhere!

Ecologists are reluctant to make use of existing data and information when conducting analyses because of concerns regarding inconsistencies in data collection, analysis and sample sizes.  This means that ecologists often feel that they must collect all the data required for a study or, conversely, that there is insufficient data to conduct the study.  But… Continue reading Data, data, everywhere!



I'm a post-doctoral researcher at the University of Melbourne.  My current projects and research interests include: - The role and influence of informative Bayesian priors in ecology; - Imperfect detectability and minimum survey effort requirements; - Using science to inform robust environmental policy, impact assessment and decision-making; - Adaptive management for native grassland restoration; -… Continue reading Welcome!
