Science and art! Sketching an antlion larvae!

Our new article appears in today's issue of Ethology:
"In the Danger Zone: Wrens Respond More Strongly to Experimentally Simulated Predators Near Their Nest"
onlinelibrary.wiley.com/doi/10.1111/...
We presented 3D-printed owls near versus far from nests of tropical wrens. How did wrens respond?

Pop songs in science papers! 🎶💃🎙️🐦

Birds are vanishing from tropical forests. Is another ‘silent spring’ coming? As mysterious bird declines crop up in the Amazon and beyond, scientists suspect climate change may be to blame

We thank the many people who supported this research.

Overall, predation risk appears to shape the evolution of vocal communication by influencing how animals signal and adjust their behavior in the presence of threats.

🧵6

Calling time (calls produced by males and females) was higher when the predator were presented near the nest.

🧵5

We found that birds responded more quickly shorter when predators were presented near the nest, both for males and females.

🧵4

The study area was a tropical dry forest of Costa Rica in Sector Santa Rosa where wrens inhabit old-growth forests and old secondary forests. Simulated owls were presented 5 m and 20m from their nest.

🧵3

We designed a multi-modal experiment to test whether the perception of a potential predador modifies the vocal behaviour of Rufous-and-white wrens (Thryophilus rufalbus) near their reproductive nest.

How do tropical wrens respond to simulated predators near their nest?

Thank you, Dan! 🦉

Our latest study is officially accepted! Dan @dmennill.bsky.social and I used 3D-printed pygmy owls to explore predator responses in Rufous-and-white Wrens. Check it out soon in Ethology. 🦉🔊🪺🇨🇷🇨🇦

AI Is Inventing Academic Papers That Don't Exist -- And They're Being Cited in Real Journals Academic articles from authors using large language model are creating an ecosystem of fake research that threatens human knowledge itself.

Academics and technologists are sounding the alarm about a growing crisis in scholarship as we know it: AI-generated citations of nonexistent papers that have infested real journals. Despite being fake, the sources are widely assumed to be authentic the more they appear in published literature.

Scientific productivity gap based on English-language peer-reviewed papers. Shown are the maximum % differences in the number of peer-reviewed papers published by female native English speakers from a high-income country (-45%), female non-native English speakers from a high-income country (-60%), and female non-native English speakers from a lower-middle income country (-70%), compared to male native English speakers from a high-income country (red flag).

Women, non-native English speakers & those form low-income countries are disadvantaged in science but by how much? We found that women with non-English first languages from low-income countries publish up to 70% fewer in English than their counterparts. 1/5

Ever wonder how birds are able to identify their nest? Jennings et al. show that nests can become scented like the birds that occupy them, which may enable birds to use olfaction to accomplish this critical task.

MSc student Connor Acorn uses a field-portable sound level meter, mounted on a tripod, to quantify the amplitude of the songs of Ovenbirds.

3 great words on a Monday morning: Accepted for publication! Our paper "Hushed disputes between noisy neighbours: Ovenbirds vary song amplitude during conflicts with territorial rivals" is coming to Animal Behaviour. 🤫🎶🐦 By Connor Acorn, Jenn Foote, and me.

Thank you, Nature Guelph, for the invitation to speak about our research on acoustic monitoring of bird migration. It was great to join such an engaged and excited group of birders for the evening.

CALENDAR ERROR: My talk to Nature Guelph is TOMORROW night, Thursday December 4. (I think that I have end-of-semester brain.) Anyone interested is welcome to join Thursday December 4 at 7:30pm: natureguelph.ca/events/eaves...

This year marks the 100th birthday of #bioacoustics, established by Ivan Regen in 1925, which studies how animals hear, produce and propagate sound.

Let’s discover this discipline with @nicolasmathevon.bsky.social, Professor of Saint Etienne University, in the first episode of Acoustic World.

Sarah Dobney presented her doctoral studies at the International Bioacoustics Congress #ibac2025 in Kerteminde, Denmark. Way to go @sdobney.bsky.social!
