Araba Bioscan 8-15 January 2021

Data for the period 8-15 January 2021

See the Araba Bioscan Project page for background information on the project and methods.


I’ve been trying to include images of interesting species that recur on multiple weeks in the hope that this makes it easier for me to understand phenology and seasonal change in community composition. I expect increasingly to use portmanteau images that show several of these species at once. For the time being, I’ve added some functionality so I can quickly crop smaller images from the views of the entire sample and use these to highlight these records.
