Cadences of the collective: conspecific stimulation patterns interact with endogenous rhythms to cue socially mediated response shifts Summary: Automated playback experiments reveal that túngara frogs alter each calling response based on conspecific stimulation patterns experienced prior to each call.

Our latest article is out @jexpbiol.bsky.social !

We show that tungara frogs adjust interaction modes to current collective chorusing dynamics based on how patterns of conspecific stimulation experienced between calls interact with their internal call rhythms

Tetrapod vocal evolution reveals faster rates and higher-pitched sounds for mammals Abstract. Using the voice to produce sound is a widespread form of communication and plays an important role across diverse species and contexts. Variation

Tetrapod vocal evolution reveals faster rates and higher-pitched sounds for mammals 🐘🦉🐸.

Mammalian hearing likely allowed the rapid diversification of their vocalizations.

Noise pollution and artificial light at night alter selection pressures on sexual signals in an urban adapter Abstract. Human-induced environmental changes can have major impacts on how individuals communicate. Species using sexual signals may experience especially

How do light and noise pollution impact selection on sexual signals? We tested mate attraction and bat predation on túngara frogs. Light and noise interact in complex ways, and light pollution shifts selection on male calling:

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...

"In our study, we find that urbanization speeds up tadpole development and increased behavioral plasticity. However, exposure to urban conditions also decreased tadpole size, which may cause adult frogs to become smaller and less attractive for mates"

Three different moments in the life of a treehopper (Campylenchia hastata). They look totally different after each of their five molts!

My NSF PRFB on the genetics of female polymorphism in hummingbirds was terminated yesterday.

I don't have much to say, I'm just sad. We've discovered so much, and could have gone so much further.

If anyone else is in the same boat, esp postdocs, please reach out, it would be good to connect.

Join us (in person or online) on Tuesday, April 8th, at 4PM (Panama time) for the STRI Tupper Seminar. I will discuss my research on how animals communicate in changing environments 🐸🌃🎤!

Found this treehopper (Calloconophora pinguis) guarding her eggs! She will later defend her hatched offspring against predators. So cool to see maternal care in insects!

New paper out today!

We studied the environmental conditions at two sponge (🧽) grounds on the northern Labrador Shelf (NE Canada).

We find that sponges and associated fauna benefit from strong tidal currents and favorable regional ocean currents.
