They find neat results. Fishers are more synchronised the longer they spend in the water, the closer they are, and the more cooperative they are (with each other). Yet, heart rate synchrony doesn't translate to fishing success (when dolphins cue)—probably because they have to cast asynchronously. 6/

They then conducted a cross-wavelet power analysis of heart rate variability, which reveals patterns of heart rate synchrony over time and across frequencies. This captures whether synchrony is in phase or anti-phase. 5/

In the second paper, @hanjabrrr.bsky.social and João Valle-Perreira fitted heart rate + GPS sensors to fishers while they fished together with dolphins. This provided simultaneous data on position and heart rate across the line of fishers.

Physiological synchrony among human fishers during collective hunting with wild dolphins | Biology Letters
Predator physiology is often overlooked in predator–prey interactions, despite its
potential to significantly influence hunting dynamics and social cooperation among
predators. We address this gap by ...
