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...

GREAT PhD opportunity at La Trobe University in Melbourne: domestic Australian student only. Deep-red vision and infrared sensing in jewel beetles. Field and lab studies, inc. electorphys, microscopy, behavioural assays. Team led by Dr Amanda Franklin. PM me for more info!

New paper out in @cp-neuron.bsky.social 🎉 What determines contextual modulation in V1? Why does the visual surround sometimes facilitate and sometimes suppress a neuron's response to its preferred stimulus?

Surprise! The Jeff Bezos-owned Washington Post is against my 5% billionaire wealth tax. I wonder why? If enacted, Bezos would owe $12 billion in taxes, and an average family of 4 would receive a $12,000 direct payment. Poor Jeff would be left with just $224 billion to survive.

New paper out on the decision strategies of bumblebees. When using visual cues to make flower choices, they switch strategy with sensory context, learning as much as necessary, but as little as possible. Based on their training time, we propose a mechanism for this switch. tinyurl.com/2r9d4jrs 🌸🐝🧠

Another stick in the wall: we removed part of male great bowerbird bower walls to test effect on courtship displays. Males didn’t just focus on rebuilding the wall, they stepped up effort across all aspects of their display, showing they flexibly invest in multiple signals tinyurl.com/4ujmkw95

I made a map of 3.4 million Bluesky users - see if you can find yourself! bluesky-map.theo.io I've seen some similar projects, but IMO this seems to better capture some of the fine-grained detail

New bowerbird paper out, we asked whether male great bowerbirds care about the light environment around the bower where they display to females. Short answer: not really. What they do care about is having a display arena with strong visual contrast on the ground. 🐦 tinyurl.com/2v7rycdz

Multiple anthropogenic stressors can negatively impact species but can a single stressor also have multiple, concurrent impacts? Here we show that light pollution creates several simultaneous impacts to the nocturnal movement ecology of a moth and a spider: tinyurl.com/5eku5bff (1/5)

Creative and important study for understanding visual processing.

Join us for your PhD! Apply by 15th Dec ⏰ to come to @bristolbiosci.bsky.social and study spider eyes, development and visual ecology under light pollution! Open to all nationalities, funded incl. stipend, set in a beautiful city, and with amazing collaborators ✨ www.findaphd.com/phds/project...

A new PhD opportunity in Melbourne!

Thrilled to announce a Postdoc opportunity in our group on the evolutionary genetics and ecology of colour. Wonderful system, great collaborators, and room to shape your own ideas. Apply by 7 Jan: jobs.helsinki.fi/job/13477181...

Larger frogs are better mimics but are more risk-averse in a nontoxic poison frog #Aposematism #WarningSignals #Ampibian doi.org/10.1093/behe...

Make sure you don’t miss our key dates for abstract submission and registration!

I forgot to share that our paper came out a few months ago! We synthesise decades of research showing that conspicuous traits consistently predict attractiveness, condition, and fitness across animals. Check it out if you’re into sexual selection and signalling! doi.org/10.1111/ele....

Very happy to see our opinion article out in @cp-trendsecolevo.bsky.social today. 🥳 We ask whether sexual signals can influence the evolutionary trajectory of naturally selected adaptations, such as protective colouration, for better or for worse 🧐 1/n doi.org/10.1016/j.tr...

New paper out in @behavecol.bsky.social! Multiple studies show that sexually selected traits such as colours can reflect the presence of pathogens/parasites, but, can defensive coloration do the same? L. Schlippe Justicia, @carodittrich.bsky.social, O. Nokelainen & I tackled that question (1/3)

I've been pretty agnostic about mantis colour vision given the evidence so far. This new paper makes a convincing case they have the processing to do so. Mantises (probably) see in colour folks!

Do you work (/want to work) with caterpillars? Or sensory systems? Or BOTH?! Well good golly do we have the paper for you! We explain the senses that caterpillars have, what they use them for, and how anthropogenic sensory pollution might be messing it all up 🐛 doi.org/10.1007/s003...

🚨Our new paper is out NOW in @jexpbiol.bsky.social 👀 Here we show that cuttlefish use visual contrast cues to inform their 3D camouflage, but these contrast cues can derive from true background features as well as exposure to dynamic lighting patterns. 🦑🔆 🔗 doi.org/10.1242/jeb....

Why do imperfect mimics (such as many hoverflies) exist? We created 3D printed replicas of flies, wasps and our own custom intermediates and then "asked" various predators what they thought of our 3D stimuli. Read all about it here: www.nature.com/articles/s41...
