"An autonomous network of acoustic detectors to map tiger risk by eavesdropping on prey alarm calls"
🐅🐅🐅🐅🐅
We used AI to do real-time detection of deer alarm calls and warn villagers when there's a tiger in the area zslpublications.onlinelibrary.wiley.com/doi/10.1002/...
Illustration of a Tiger Lily from Edwards's Botanical Register (1829-1847), showing a large, vibrant orange flower with six broad, curved petals speckled with dark spots. The flower’s stamens and pistil are prominently displayed in the center, with long anthers. Below, the stem supports multiple elongated, lance-shaped green leaves arranged in whorls, each leaf featuring detailed parallel veins. The artwork is finely detailed, emphasizing the plant’s structure and coloration against a plain background.

So excited to share our new work out in @evolletters.bsky.social today!
doi.org/10.1093/evle...
Sexual signals and preferences for them often differ across groups, contributing to reproductive isolation. But how do new signals evolve if females already have preferences for existing ones? (1/4)
It turns out it's not so straightforward to define a vocalisation, when you whistle or tongue click you are not vocalizing (in my opinion).
A fascinating discussion indeed :)
Wrote more about it in my thesis:
Now out in Evolution @journal-evo.bsky.social
Tetrapod vocal evolution reveals faster rates and higher-pitched sounds for mammals 🐘🦉🐸.
Mammalian hearing likely allowed the rapid diversification of their vocalizations.

Happy to share our new paper is now published! 🎉
We developed a non-invasive method to model animal hearing using 3D photogrammetry and showed it on bats 🦇 and a pig. It even allowed us to capture the 3D mesh of an alive and awake bat and model its hearing! 🔉

Historical illustration from the 1912 "Handbook of Birds of Eastern North America," showing detailed black-and-white side profiles of 15 different duck heads, each labeled with its species name. The ducks include Baldpate, Green-winged Teal, Blue-winged Teal, Shoveller, Pintail, Wood Duck, Redhead, Canvasback, American Scaup Duck, American Golden-eye, Bufflehead, Old Squaw, Greenland Eider, White-winged Scoter, and Ruddy Duck. Each head is carefully drawn to highlight distinctive beak shapes, feather patterns, and plumage details, arranged in a grid labeled "Plate XII." The image reflects early 20th-century ornithological study and documentation but is unrelated to the keyword "apple."

Illustration of the fossilized bones of a Mastodon giganteus foot from the 1852 publication. The detailed black-and-white drawing shows large, rugged bones including the ankle and toe joints, labeled with letters for identification. The bones appear textured with visible surface irregularities, highlighting the massive structure of the extinct prehistoric mammal. The image is set against a plain background with the title "Mastodon Giganteus" below.

Our article was just published in Integrative & Comparative Biology! Here, we ponder how different interaction strategies lead to differences in call-timing mechanism functioning, and propose amendments to several prominent frameworks from the chorusing literature. academic.oup.com/icb/article-...

Illustration from "Brehms Tierleben" (1911-19) depicting a thick-tailed possum clinging to a large, cylindrical yellow flower with fine, hair-like petals. The possum has soft brown fur, large dark eyes, rounded ears with pink insides, and a long, thick tail wrapped partially around the flower. Green leaves and stems surround the flower at the base. The detailed, naturalistic style highlights the possum’s cuddly appearance and its close interaction with the flowering plant. The background is a muted blue, emphasizing the animal and flora in the foreground.

Buddy, I can see mountains reflected in the eyes of a trailside pika.
These are the most challenging times for early-career scientists and engineers.
My team is doing its bit to help by maintaining and even expanding our database of funding opportunities for early-career researchers.
We found 437 of them.

Acoustic monitoring is everywhere this days. But how far can we really detect a bird acoustic within a tropical forest? 🧐🎙️
To answer this questions we built sound attenuation models for two Neotropical birds and estimated they detection ranges.

Do birds tune their songs to their hearing?
Is there tight coevolution between avian vocal signals and hearing-or do signallers and perceivers evolve more loosely?
It turns out perfect tuning is not required...

Hello, can I be added?
We did these recordings during summer in our garden in Scotland, and will keep trying to record bees the next season! Setting up some passive acoustic recording of audio + video on some flower patches would be ideal for building a library...
I dont think there is anything like that because there is not very many focal recordings of wingbeats. So it would be hard to know what made the wingbeat in an PAM rec.
Some recent articles:
www.sciencedirect.com/science/arti...
royalsocietypublishing.org/doi/10.1098/...
Because different species produce different wing beats. 🔊
Compare the common carder bee above to the honey bee here! 🍯 🐝
