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 🌸🐝🧠

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.

A grey/brown male great bowerbird is looking towards the camera and in the background is a U shaped structure made of sticks, called a bower. Part of one of the walls is missing. In front of the bower is a pile of white, green and red objects called decorations that the male uses as part of his display.

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'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)

Synthesis of Nature's Extravaganza: An Augmented Meta‐Meta‐Analysis on (Putative) Sexual Signals Conspicuous traits like bright colours and elaborate displays are widely thought to evolve through sexual selection, but evidence has been scattered.

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. πŸ₯³ 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

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!
