Abstract Defaunation is an increasingly pervasive process, reaching ever larger spatial scales worldwide. We integrated data on thousands of putative local mammal assemblages across the Neotropics into 518 metacommunities to predict phylogenetic trait‐based effects regional defaunation—here defined as meta‐extirpation (i.e. extinction at metacommunity level)—on dozens ecosystem services (ESs). Further, based 1029 real‐world coalesced 236 metacommunities, we assessed extent meta‐extirpations Neotropics, while empirically quantifying losses in ESs comparison with scenarios. Using observed data, also sought understand changes mean body size for different dietary guilds. examined patterns diversity, evaluated erosion ecological networks and measured relationships between diversity metrics via dissimilarity arrangements generalized linear models. Meta‐extirpation regimes lead a loss 49.6% provided by Neotropical mammals within whereas derived 47.2% ES loss. show that simulated penalizing large‐bodied species, induced most severe ESs. Regional‐scale metabolic allometry trophic structure consumers, inducing significant downsizing. conclude once‐thriving mammal‐mediated roles natural ecosystems are fading, consequences human livelihoods. Many populations have succumbed several ecoregions; so it critical protect representative fractions landscapes species pools. Finally, reinforce appeal effective conservation action, given already global reality.
