Spider Monkeys Mapped by Sound
A jungle-scale sensing system that turned hard-to-see movement patterns into something map-like and operational.
Hundreds of forest audio recorders and detection models revealed where endangered spider monkeys disappear near roads.
This is a particularly good field-systems story because the deployment does not stay abstract. Recorders are spread through the forest, models sift the sound, and the result is not a vague claim about biodiversity but a concrete map of where the monkeys stop appearing.
The finding matters. Roads are not just infrastructure on a map; they change movement patterns in ways that become visible once the sensing layer is good enough.
It is a Dispatch fit because the system is both beautiful and severe: remote hardware, messy signal, ecological stakes, and a result that changes what people can act on.
