ABSTRACT Synanthropes are known for their remarkable adaptability to coexist with humans, yet increased visibility exposes them significant threats, such as hunting or conflict over resources. Moore et al. 's review ‘The rise of hyperabundant native generalists threatens both humans and nature’ ( https://doi.org/10.1111/brv.12985 ) explores distribution patterns impacts macaques pigs in anthropogenic environments. Our critical evaluation this study revealed several substantial issues: the pooling data from species that ecologically behaviourally distinct, an error acquisition, potential biases statistical analyses, misrepresentations threats wildlife human‐impacted habitats. Additionally, we highlight lack evidence supporting authors' core assertion hyperabundance species. While compare densities abundance across various habitat types, analyses did not demonstrate population increases time. On contrary, our re‐analysis sets showed a decreasing trend Macaca nemestrina absence M. fascicularis 44% surveyed habitats characterized by medium high forest integrity. Further, findings emphasize importance intact forests predicting relative pigs. Overall, recommend more careful interpretation data, can result negative sensational discourses about overabundance, which may threaten conservation often thrive landscapes.

Positive reinforcement and training for health optimization are pivotal successful studies with monkeys. Potential food inclination is important on crab-eating macaques in laboratory environments, but evaluations remain scarce. We explored macaques’ potential to establish a reward system future behavioral assessments. Twelve male three female monkeys underwent assessment which they were offered four categories—fruits, vegetables, proteins, nuts. The exhibited higher plant-based foods, particularly fruits over animal-based proteins like chicken tuna (p < 0.0001), notable nuts (eaten/provided = 100%). Additionally, the consistency of after repeated offerings was investigated, revealing time-dependent increase protein items. Food consumption ratios correlated positively caloric intake (r 0.59, p 0.02), implying that individuals regular high increased body weight more likely accept during positive training. Our findings suggest fruits, protein-rich can help optimization. However, foods initially had low preference, may time. study provide guidelines
