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.

Potential Food Inclination of Crab-Eating Macaques in Laboratory Environments: Enhancing Positive Reinforcement Training and Health Optimization

Animals, Год журнала: 2024, Номер 14(7), С. 1123 - 1123

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

Isolation and Biochemical Characterisation of Long-Tailed Macaque Aerobic Gut Bacteria from Tinjil Island, Indonesia

Indonesian Journal of Primatology, Год журнала: 2024, Номер 3(01), С. 1 - 17

Long-tailed macaque (Macaca fascicularis; LTM) is a common non-human primate used as an animal model in the medical field for its genetic similarity with humans. Maintaining gut microbiota balance of LTM crucial to avoid possibility disease caused by dysbiosis. Therefore, this study aims isolate bacteria from semi-wild Tinjil Island know diversity their microbiota. We serially diluted four fecal samples and spread them onto nutrient agar medium enumeration through Total Plate Count (TPC). Then, we follow Bergey's Manual Determinative Bacteriology. The isolates would be identified morphologically biochemically. average total viable obtained was 1.86 x 109 CFU/g. Aerobic isolation all resulted 19 gram-positive bacteria, which six putative species Staphylococcus sp., three Bacillus Micrococcus Corynebacterium sp. In general, isolating cultivable has provided overview composition based on limited analytical methods using cultured-dependent methods.
