How do we know the extend of biological invasions? Is it a large invasions? A small one? How do we compare invasions of tiny organisms (e.g., ants) and of larger ones (e.g., rabbits)? How do we quantify objectives, or efficiency of management? See our new paper in BioScience! 👇 tinyurl.com/ynuk8cm7

When plants or animals move, or are moved, to a place they don't belong, there is a risk of damage to natural habitats and an economic cost too. @franckcourchamp.bsky.social talks to @talknormal.co.uk about how we estimate the size of this risk and what we can do about it cepr.org/multimedia/h...
