Abstract Obtaining accurate population measures of endangered species is critical for effective conservation and management actions to evaluate their success overtime. However, determining the size demographic composition most canopy forest-dwelling has proven be challenging. Here, we apply two non-invasive biomonitoring methods, arboreal camera trap genetic tagging faecal samples, estimate a critically primate, northern muriqui ( Brachyteles hypoxanthus ), in Caparaó National Park, Brazil. When comparing sizes between trapping tagging, survey estimated fewer individuals one groups studied but showed slightly higher estimates other group. In terms cost-efficiency both had high initial costs was more cost-effective long-term. Genetic on hand did not require expensive equipment data collection associated expenses laboratory consumables processing. We recommend use methods monitoring provide suggestions improving implementation these future routine monitoring. Our findings also highlight potential mammals tropical forests.

Diversity of the gut microbiota has proven to be related with host physiology, health and behavior, influencing ecology evolution. Gut microbial community relationships often recapitulate primate phylogeny, suggesting phylosymbiotic associations. Howler monkeys ( Alouatta ) have been a model for study host-gut relationships, showing influence different environmental factors. Differences in life-history traits feeding behavior other atelids, like spider monkeys, may reveal distinct patterns bacterial communities, yet few wild populations studied; likewise, studies hybrid are mostly lacking. We analyzed diversity abundance three Mexican primates Ateles geoffroyi, palliata A. pigra from regions across its distribution country, including sympatric localities zone. Interspecific differences were higher than intraspecific differences, concordant phylosymbiosis. harbored more differentiated major presence rare taxa, while less strong between species. Hybrids had in-between their parental species, also unique microbe taxa. Genetic distances individuals correlated positively dissimilarities. Results show that interspecific overall diversity, composition affected by environment, geographic genetics. Our provides first comprehensive populations.
