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/

How do we know our research results are REAL? We replicate them! Most folks agree but lament on how hard it is to publish these replications. My dearest gentle reader, lament no more! Delighted to unveil: Replication Studies, a new section of Behavioral Ecology 1/ academic.oup.com/beheco/artic...

Replication studies: a win-win for early-career training and behavioral ecology

Replicating previous research builds confidence that results are real and meaningful. But close replications are rare due to limitations in resources and d

Pace of ecology drives the tempo of visual perception across the animal kingdom www.nature.com/articles/s41... - new paper with Clinton Haarlem, Cliodhna Hynes and colleagues Different species see the world as fast as they need to...

Pace of ecology drives the tempo of visual perception across the animal kingdom - Nature Ecology & Evolution

Using phylogenetic comparative methods across 237 species from disparate phyla, the authors show that species with fast-paced ecologies have higher temporal resolution of perception.

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...

Have you ever wondered what you would find if you could keep your eyes on a bee for more than a few meters? Us, too! preprint (with videos!) + thread 🧵 Precise, individualized foraging flights in honey #bees 🐝 revealed by multicopter drone-based tracking www.biorxiv.org/content/10.6... 1/9

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. @jki-research.bsky.social @nabu.de doi.org/10.1111/icad...

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 .....

Lab member and hacker extraordinaire Victor Titov has entered the Component Abuse Challenge @hackadayofficial.bsky.social with the LEDs on our bee tracking drone. hackaday.io/project/2043.... Check out the video! Thanks @volkswagenstiftung.de @dfg.de @biologyunifreiburg.bsky.social @uni-freiburg.de

overdriving LEDs, for the bees

This project is about maxing out the LEDs. Can we drive them harder than the datasheet allows? We need this to overpower daylight, to see bees that wear retroreflective markers, as if was at night.

Look - it's a new preprint! Predatory attacks change bee visual perception and decision-making, making bees better prepared to detect threats. Excellent work by the brilliant Olga Procenko for her (prize-winning) PhD with us! #bees #vision #predation www.biorxiv.org/content/10.1...

Acute stress modulates early visual perception and decision-making speed in bees without compromising accuracy

Acute stress is known to influence decision-making, but it can also directly affect earlier stages of sensory processing. In humans, stress alters the perception of basic visual features, fine-tuning ...

Reports of insect decline are not new but they are worsening. International data has estimated annual losses between 1%-2.5% each year. But this is a newer phenomenon: catastrophic collapse of insect populations in supposedly protected regions that are free of destructive insecticides & pesticides:

‘Half the tree of life’: ecologists’ horror as nature reserves are emptied of insects

A new point in history has been reached, entomologists say, as climate-led species’ collapse moves up the food chain even in supposedly protected regions free of pesticides
