CSI: Ecology. Efficiency of eDNA sampling

Detecting a species from the DNA it left behind seems so much like CSI: Ecology. DNA deposited in the environment (eDNA for the cool kids), which can then be collected and identified, is increasingly advocated for ecological studies (Ficetola et … Continue reading

Detectability and traits of plants

If you’ve seen previous posts, you would realise that I am interested in the topic of imperfect detectability in field surveys. I’m interested in what influences detectability, how to account for it in analyses, and what it means when designing … Continue reading
