Understanding partial migration: linking genetic, developmental, and environmental drivers
Partial migration, where some individuals in a population migrate while others remain resident, arises from the dynamic interplay of multiple non-exclusive eco-evolutionary mechanisms. These mechanism...

Ever wondered why individuals within the same species migrate differently? Or what drives some animals to become partial migrants? Then, this paper is for you!
Our new paper synthesizes the ecological and evolutionary mechanisms that shape partial migration.

We have a preprint about modelling three-dimensional movement tracks, led by @njklappstein.bsky.social.
The model takes the form of a step selection function and, just like in 2D, it can include directional persistence, attraction to targets, and habitat selection.

Have you ever wondered if we can detect disease in wildlife just by looking at their movement?
We show how hidden Markov models can link animal trajectories to infection states — tested on reintroduced scimitar-horned oryx and simulated data.
