Can’t see the puffins for the auks? Estimating population size with imperfect species identification

In this post, Alison Johnston (@ali__johnston) talks about her paper published today “Modelling the abundance and distribution of marine birds accounting for uncertain species identification”. Ecological surveys balance the competing goals of data quality and data quantity. We can intensively survey a small area, or cover a larger area with less detail and precision, for example in large-scale citizen science surveys. Recently there has been … Continue reading Can’t see the puffins for the auks? Estimating population size with imperfect species identification

Consequently, large marine vertebrates such as seabirds, turtles, … Continue reading Eyes in the sky see the secrets of the sea
