Thanks, Jorge. Yeah, branching itself is compelling, especially for a naturally continuous trait like preferences.
Also related is this from Alex et al with branching in a belief/preferences leading to fragmentation.

Still, relatively few studies like these.
Very interesting, Jorge. I hadn’t seen adaptive dynamics applied to preference traits like this.
Is the branching and long-term polymorphism you find unique to adaptive dynamics, ie the stable polymorphism would not occur in discrete-trait models?
🧵 New paper w/ Guillaume Cheikbossian: "Evolutionary branching of social preferences in a public good provision game" (ideas.repec.org/p/tse/wpaper...). Can behavioural heterogeneity in cooperation be an adaptive outcome? We think the answer is yes.
Tempo comparison across scales, taxa, modalities, and media. Top left: Spectrogram of cricket(s) chirping for 1 min. Top right: Spectrogram of nearby fireflies flashing for 1 min (N = 21). The colorbars in both heatmaps correspond to Power/frequency (dB/Hz). Bottom: Typical tempos at which different animals signal vs. their respective mean body weights on a logarithmic scale (N = 24). The plot consists of six main groups: insects, amphibians, birds, fish, crustaceans (these last four in an overlapping region due to similar weights—note that the labels here don’t necessarily correspond to specific points as the species are mixed), and mammals. The icons (light bulb, speaker, and a moving human) represent the form of the signal (light, sound, or gesture). Note that the signals are mostly transmitted through air, with two examples through water (both fish, written in blue).
Do animals have a favored tempo for communicating with each other? This study reveals a hotspot of 0.5-4 Hz for #communication across distinct species & modalities, hypothesizing that this may driven by biophysical commonalities of the receivers' #neurons @plosbiology.org 🧪 plos.io/4ccWuhh
Pinchy!
We are recruiting 1-2 postdoctoral fellows to investigate the specificity of human anti-influenza virus antibodies, and to determine how these antibodies impact global antigenic drift of influenza viruses.
