Effective spatial scales for evaluating environmental determinants of population density in Yakushima macaques

Research identifies the optimal spatial scale for assessing environmental factors influencing Yakushima macaque population density, finding that a 400-meter radius best correlates with group range size. The study highlights broad-leaved forests as positively impacting macaque density, while mixed forests and forestry areas negatively affect it. Conducted across 30 sites using data from 403 automatic cameras, the research evaluates natural vegetation types, altered habitats, hunting pressure, and feral dog densities. By employing generalized linear mixed models, the study emphasizes the need for simultaneous evaluation of all potential factors at appropriate spatial scales to inform effective conservation strategies.
