## TL;DR

This study reveals how eco-evolutionary feedbacks between spatial mixing and predator perceptual ranges influence prey-predator coexistence, with implications for community stability and species extinction risk.

## Contribution

It demonstrates the interaction between spatial structure and predator perceptual evolution, a novel insight into eco-evolutionary dynamics in prey-predator systems.

## Key findings

- Spatial mixing influences predator perceptual range evolution.
- Eco-evolutionary feedback affects prey and predator spatial distributions.
- Community stability and extinction probabilities are controlled by these feedbacks.

## Abstract

Eco-evolutionary frameworks can explain certain features of communities in which ecological and evolutionary processes occur over comparable timescales. Here, we investigate whether an evolutionary dynamics may interact with the spatial structure of a prey-predator community in which both species show limited mobility and predator perceptual ranges are subject to natural selection. In these conditions, our results unveil an eco-evolutionary feedback between species spatial mixing and predators perceptual range: different levels of mixing select for different perceptual ranges, which in turn reshape the spatial distribution of prey and its interaction with predators. This emergent pattern of interspecific interactions feeds back to the efficiency of the various perceptual ranges, thus selecting for new ones. Finally, since prey-predator mixing is the key factor that regulates the intensity of predation, we explore the community-level implications of such feedback and show that it controls both coexistence times and species extinction probabilities.
