Thanks Vivek, it happened. See you in Edinburgh?

Haha, thanks Benito - there is certainly plenty more colsci to come.

We conclude that whether animals evolve camouflage or warning colouration as their antipredator strategy depends on multiple mechanisms. This helps explain the evolution and global distribution of camouflaged and warningly coloured animals. 6/6

Several other variables were important too, including whether the predator community had lots of insectivore specialists, the colours of other butterflies and moths in the prey community, and how gloomy the forest was. Please take a look at the paper for details! 5/6

We found predator competition had the largest effect, and it was bad news for prey with warning colouration – they were more likely to be sampled but slow to be learnt when hungry predators were competing for resources. 4/6

In 21 different forests we exposed over 15,000 camouflaged and warning coloured artificial ‘moths’ to avian predation 🐦‍⬛.

How do differences in predator and prey communities and light environment between locations affect predation on each colour strategy? 3/6

Iliana Medina and I assembled a team of 50+ amazing collaborators inc.
@jmappes.bsky.social @hannahmrowland.bsky.social hmrowland.bsky.social @facasaro.bsky.social saro.bsky.social @jtroscianko.bsky.social + many not on Bsky to run a field predation experiment across six continents. 2/6

📢🦋 Our paper ‘Global selection on insect antipredator coloration’ is out and featured on the cover of @science.org

We ran a huge experiment to find out how ecological context favours camouflage and warning colouration as antipredator strategies. 1/6

Matt Sparks, my PhD student, and Roger Santer wrote a very interesting article for The Conversation on fly vision, and why understanding it better can help prevent human disease. theconversation.com/how-a-fly-se...

Confused writing is usually a symptom of confused thinking. As we struggle to clarify writing, we clarify our thoughts. AI writing aids rob us of that struggle, leaving clean-looking text and thoughts still confused for lack of inspection. Writing is not just a product; it is a diagnostic tool.

Depressing stich-up by the right-wing press. Rayner is an inspiration to everyone trying to get on in life after a difficult childhood, and for helping others to do the same. I hope she is back in Government soon.

New paper @biolinvasions.bsky.social led by Sarah-Sophie Weil.

Can macroevolution inform contemporary invasion potential?

We outline the assumptions of this approach, assess support, then test if dispersal ability can proxy for naturalisation success in several tetrapod groups.

@riadsala.bsky.social and I have been spending a long time thinking about modelling visual foraging. v2 model glow up: 1) it can account for individual diffs in lots of summary stats 2) it can deal with 'outliers' really nicely and 3) it should be easier to use! osf.io/preprints/ps...

Pick an idiom: "more than meets the eye", "beauty more than skin [feather] deep" etc.

In work led by Rosalyn Price-Waldman, we describe a hidden (and ignored!) black or white layer found below the visible surface of bird feathers which helps make bird colours so striking!

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...

Birds have an excellent ability to learn to discriminate harmless insects from those that they mimic on the basis of subtle differences in appearance.
