What is it about?
This study used a large mark-release-recapture dataset and investigated the effect that expanding a study area has on the maximum dispersal distance detected. We found that the original study (on the endangered southern damselfly, Coenagrion mercuriale) was at a scale sufficient to estimate the maximum distance that the insect is able to fly, around 2km.
Why is it important?
The southern damselfly has very specific habitat requirements (water meadows and shallow ditch systems) which mean that it has a long distance to move between these rare areas. This study showed that we can trust our estimates of how far the animal can move, which will help to plan its conservation.
