Increasing interface zones between long-tailed macaques (Macaca fascicularis) and humans can increase macaques' risk-related behaviors to human safety because of their aggressiveness. In addition, risk to human properties and the environment can occur when they play or search for food and other stuff on vehicles and take trash out from trash bins to find edible items.
Objective
This study aims to develop a YOLOv8-based detection system for identifying long-tailed macaques and their risk-related behaviors in a university campus, with enhanced robustness through data augmentation and Genetic Algorithm–based hyperparameter tuning to support early warning and deterrent system.
Methods
We developed a You Only Look Once version 8 (YOLOv8)-based object detection system to identify macaques and recognize risk-related behaviors within a multi-purpose university campus environment. A dataset of annotated images and video frames compiled from on-site observations was supplemented by using data-augmentation techniques such as Mosaic, MixUp, and geometric transformation to improve robustness under varying environmental conditions. Model performance was further improved through Genetic Algorithm (GA)-based hyperparameter tuning.
Results
The experimental results show that the system could detect macaques and contextual objects in real-time with strong performance across diverse scenes, even when they were camouflaged or partially occluded.
Conclusions
The findings indicate that this approach could be used to provide an automated early warning and deterrent system to help reduce human–macaque negative interaction.
背景：长尾猕猴（Macaca fascicularis）与人类之间界面区域的增加会增加其对人类安全的风险相关行为，因为它们具有攻击性。此外，当它们在车上玩耍或寻找食物和其他东西，从垃圾桶里拿出垃圾寻找可食用的东西时，可能会对人类财产和环境造成风险。目的：开发基于yolov8的大学校园长尾猕猴及其风险相关行为识别系统，并通过数据增强和基于遗传算法的超参数调优增强系统的鲁棒性，为预警威慑系统提供支持。方法：我们开发了一个基于You Only Look Once version 8 （YOLOv8）的目标检测系统，用于识别多用途大学校园环境中的猕猴并识别与风险相关的行为。通过使用马赛克、MixUp和几何变换等数据增强技术来补充现场观测的注释图像和视频帧数据集，以提高在不同环境条件下的鲁棒性。通过基于遗传算法的超参数整定进一步提高了模型性能。结果：实验结果表明，该系统可以实时检测猕猴和上下文对象，并且在不同场景下具有较强的性能，即使它们被伪装或部分遮挡。结论：研究结果表明，该方法可用于提供一个自动预警和威慑系统，以帮助减少人类与猕猴的负面互动。

Background
The ability to study in vivo microvascular flow within the placenta is limited. We sought to compare two techniques for evaluation of placental perfusion in a translational nonhuman primate model.
Methods
We measured placental microvascular perfusion in six pregnant African green monkeys (Chlorocebus aethiops sabaeus) using both Laser Doppler Flowmetry (LDF) and contrast-enhanced ultrasound (CEUS) in 2–4 discrete placental locations per animal at early- (EG), mid- (MG), and/or late-gestation (LG). We assessed correlation between matched LDF and CEUS, with the hypothesis that we would observe concordance between these two measures of relative perfusion.
Results
Using 35 total paired measurements (13 EG, n = 4; 12 MG, n = 4; 10 LG, n = 5), we found no correlation between LDF microvascular perfusion and CEUS microvascular flux rate (Pearson r = −0.2026, R2 = 0.0411, p = 0.2431).
Conclusion
LDF and CEUS produce discordant results with respect to placental perfusion. LDF is ill-suited to a heterogeneous organ such as the placenta.
背景：研究胎盘体内微血管流动的能力是有限的。我们试图比较两种技术评估胎盘灌注在翻译非人灵长类动物模型。方法：我们使用激光多普勒血流仪（LDF）和对比增强超声（CEUS）在妊娠早期（EG）、中期（MG）和/或妊娠后期（LG）测量了6只怀孕的非洲绿猴（Chlorocebus aethiops sabaeus）的2-4个离散胎盘位置的胎盘微血管灌注。我们评估了匹配LDF和CEUS之间的相关性，假设我们将观察到这两种相对灌注测量之间的一致性。结果：共35个成对测量（EG 13个，n = 4； MG 12个，n = 4； LG 10个，n = 5），我们发现LDF微血管灌注与CEUS微血管通量率无相关性（Pearson r = -0.2026, R2 = 0.0411, p = 0.2431）。结论：LDF与超声造影对胎盘灌注结果不一致。LDF不适合异质器官，如胎盘。

Diabetes mellitus (DM) is a common condition affecting non-human primates (NHPs). The use of serum fructosamine in NHPs is a useful monitoring tool. Data does not exist to show whether there is any correlation between glycosuria and serum fructosamine. The purpose of this case series was to evaluate if there is a correlation between these two measurements to inform future monitoring of diabetic NHPs.
Methods
Two De Brazza's monkeys (Cercopithecus neglectus) and one tufted capuchin (Sapajus apella) previously diagnosed with DM underwent daily urinalysis monitoring. The average of each individual's morning (AM) glycosuria scores for the two weeks preceding a blood serum fructosamine measurement was calculated and then compared to their serum fructosamine measurement.
Results
In each of the three cases, a strong positive correlation between glycosuria value and serum fructosamine was observed.
Conclusion
Urine glycosuria appears to be a useful non-invasive diagnostic monitoring tool in NHPs with DM.

Callitrichid primates Saguinus bicolor and Saguinus midas from urban accidents in peri-urban forests from Central Amazon were necropsied. Analysis of thoracic and peritoneal fluid showed that 56.5% (13/23) of S. bicolor individuals and 13.3% (4/30) of S. midas individuals had the presence of Dipetalonema and Mansonella (Tetrapetalonema) microfilariae.

Cynomolgus macaques are widely used in biomedical research, yet the hybridisation between the subspecies M. f. fascicularis (Mff) and M. f. aurea (Mfa), and introgression from another species M. mulatta (Mm) may affect the research outcomes.
Methods
DNA barcoding targeting COI mtDNA, as well as phylogenetic, pairwise distance and statistical analyses were employed to examine the relationships between Mff, Mfa and Mm using 52 newly sequenced and 59 public DNA barcodes representing 17 Macaca taxa and seven species groups.
Results
DNA barcoding delineated the Macaca taxa, revealing genetic distinctions between Mff and Mfa greater than between Mff and Mm, as well as delineating geographical populations. This underscores the need for verification of laboratory individuals, besides genetic management of breeding colonies, as genetic differences can influence disease susceptibility and drug trial outcomes.
Conclusions
DNA barcoding offers a rapid, cost-effective tool to ensure appropriate selection and genetic management of laboratory individuals used in biomedical research.
