Visual ecologist at Exeter University. I study how visual information affects the ecology, behaviour, survival and conservation of many different animals. Areas of interest include camouflage, signalling, visual modelling and artificial light at night

#ASABWinter2025

The final schedule for Winter ASAB is finalised, and we've got an absolutely fantastic line-up. We had 176 talk abstract submissions and just 24 slots - can't wait to see them. asabwinter.github.io/2025/schedule/ @asab-meetings.bsky.social

Our BehaveAI paper has just come out! Easy & effective tracking & behavioural classification, even with tiny (2px), fast moving, camouflaged objects. Paper: doi.org/10.1371/jour... Download: github.com/troscianko/B... @uniexecec.bsky.social @kevinjgaston.bsky.social @jimamclgalloway.bsky.social

Many thanks to all authors, namely to @scienceanna.bsky.social, @lisandrinamari.bsky.social, @jtroscianko.bsky.social, V. Jelínek and T. Albrecht, to all participants that played the egg game, to our research institute @ivb-cas.bsky.social of @czechacademy.bsky.social. And of course, to all BIRDS!

Moths move significantly less when exposed to artificial nighttime light, new research from the Centre for Ecology and Conservation at the University of Exeter, Cornwall shows. Read More: news.exeter.ac.uk/faculty-of-e... @uniexecec.bsky.social #ExeterEcology

Well this is a big one the largest paper from my PhD is finally out! We show how direct lighting influences optimal camouflage! With shadows promoting the evolution of darker, striped patterns and countershading!! journals.plos.org/plosone/arti...

Despite advances, quantifying complex motion info remains challenging. @jtroscianko.bsky.social @kevinjgaston.bsky.social &co present BehaveAI, a #video analysis tool that sees motion as color, tracking animals & classifying #behavior in complex natural scenes @plosbiology.org 🧪 plos.io/4kTF1wX

This grass moth is often invisible in still frames, but easy to see in motion. BehaveAI can use this motion to track tiny & camouflaged moving objects in complex scenes. Its semi-automated annotation workflow also means this moth-tracker took only an hour to make. Preprint: tinyurl.com/BehaveAI

Eye-opening findings on how light suppresses moth activity. Light attracts moths, but what if we've been missing a much more pervasive effect where even sky-glow light levels make them freeze? Paper: doi.org/10.1098/rspb... @uniexecec.bsky.social @esbriolat.bsky.social @kevinjgaston.bsky.social
