Modelling three?dimensional space to design prey refuges using video game software

© 2021 The Authors. Refuges can be ecologically important, allowing access only to some species or individuals and providing prey protection from predators. Creation of refuges used protect threatened introduced predators, which have large negative impacts that are difficult attenuate via other means. To design for conservation purposes, refuge accessibility different must understood. Traditional techniques not adequate measure describe complex three-dimensional spaces often important refuges. We designed a novel predictive method modeling space using video game software simulates real-world physics (Unity, PhysX). use the study system endemic New Zealand skinks (Oligosoma spp.), their house mice (Mus musculus), habitat interstitial within rock piles demonstrate how this technique inform enhancement conservation. model realistic spaces, found we predicted matched those measured in real computed tomography (CT) scanning. information about sizes gaps accessible results our determine optimal size rocks create would mice. determined ideal with graded diameters 20–40 mm. approach developed could habitats as they naturally occur, it applied benefit particular species.
