I'm a Professor in the Faculty of Biology at the University of Freiburg, Germany. I'm fascinated by visual navigation in insects. We study this and also develop tools to help us with that. https://strawlab.org/

Team der #UniFreiburg um Prof. Dr. @andrewstraw.bsky.social hat untersucht, wie #Honigbienen navigieren. Die Forschenden fanden heraus, dass jedes Tier eine eigene bevorzugte Route hat und diese sehr prΓ€zise abfliegt – visuelle Orientierungspunkte wie BΓ€ume helfen dabei. ➑️ ufr.link/bienennavigation

Using our bee-tracking drone, we discovered that honey bees 🐝 have highly precise and individual routes. Now published at @currentbiology.bsky.social : doi.org/10.1016/j.cu...

With some trepidation, I'm putting this out into the world:
gershmanlab.com/textbook.html
It's a textbook called Computational Foundations of Cognitive Neuroscience, which I wrote for my class.

My hope is that this will be a living document, continuously improved as I get feedback.

Locating nests of endangered bumble bees: Lessons from field trials in northern Germany Tracking bumble bees to find their nests using coloured strips of paper stuck to their thorax proved to be the most suitable method, while radio transponders were too heavy. Tracking times of up to .....

We discuss various strategies for locating nests of the rare and endangered above-ground nesting bumblebee species Bombus muscorum. Although we did not find any nests, we were able to track bees marked with paper strips for up to 800 m.

The tracks are 3D. We have stereo cameras on one drone. But indeed more drones would be better and help with occlusion.

This work is a technical demonstration that multicopter drones can track honey bees in 3D across landscapes with trees and other structure.

Huge thanks to the @volkswagenstiftung.de who believed in our original "high-risk" idea. Also to @dfg.de for later funding to improve tracking precision.

Heat map showing the proportion of flight aligned to the target "Inbound - Gap", at different angular thresholds when the trajectories are divided into 20 segments.

Relating to the waggle dance, @freelyflyingbees.bsky.social, @schuemaa.bsky.social, and others have shown this dance is somewhat imprecise. Our results suggest this dance imprecision is not constrained by limits in bees' spatial representation. (Maybe, like me, they are just bad dancers.)

Scatter plots of bee trajectories crossing planes at select locations along their route.

Scatter plots of bee trajectories crossing planes at select locations along their route.

The precision with which the bees repeatedly fly the same route surprised us. At one location near a prominent tree, we measured for each bee a spread of just 50 centimeters around the median. Elsewhere, over a cornfield, the trajectories were more variable.

Outbound and inbound trajectories from two bees.

Outbound and inbound trajectories from two bees.

We discovered individual honey bees typically have their own preferred route and, in the vicinity of nearby landmarks, fly repeatedly very nearly the same trajectory.

@mnjeschke.bsky.social @martinegelhaaf.bsky.social recently found similar in bumble bees in lab-based tunnel experiments.

Bee with reflective marker.

Bee with reflective marker.

We selected bees that had learned to forage from our sugar-water feeder. Such bees were flying repeatedly back-and-forth every few minutes and, after catching them, we would glue a reflector to them and release them again. (And we were often able to remove the reflector again when done.)
