Yet, it is unknown how well altricial mammals such as mice parallel primate and specifically human craniodental development. To address this, here we document the ontogeny of jaw-related structures in a cross-sectional prenatal sample of mouse lemurs (<i>Microcebus</i> spp.). Mouse lemurs follow the same developmental sequence as humans and mice with respect to the earliest appearance of jaw structures. Meckel's cartilage forms before any membranous bone of the mandibular body; mandibular basal bone begins to ossify before teeth enter the bud stage. Lower jaw structures commence morphogenesis before the corresponding maxillary elements. The basal bone of both jaws becomes more complex in larger fetuses. As tooth germs mature, the follicle—a supporting connective tissue outside the papilla and enamel organ—matures into a cellular, loosely fibrous tissue. Surrounding the follicle is a sheet-like connective tissue, the <i>epifollicular membrane</i>. In tooth germs reaching the bell stage, alveolar bone forms within this membrane. One subtle distinction of mouse lemurs to prior descriptions of fetal anthropoids is the lemur's faster maturation of the deciduous canine compared to incisors, the reverse of the anthropoid pattern. However, broadly it appears that all primates studied thus far have a very prolonged duration of dental maturation, which continues long after other facial elements (e.g., hard palate) are fully formed. This scenario contrasts with altricial rodents, in which palate formation occurs near parturition, and only a day before the first permanent molar reaches the bell stage.</p></div>","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147497286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our aim is to highlight the urgent need for (1) thoughtful, evidence-based coexistence strategies as cities continue to expand into primate habitats and (2) primatologists, conservationists, urban planners, and policymakers to play an active role in integrating primate ecology into land-use and tourism policies to ensure the long-term persistence of primates and the socio-ecological systems they inhabit.</p></div>","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147497274","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We deployed autonomous audio recorders to measure vocal activity in the Critically Endangered Nosy Be sportive lemur (<i>Lepilemur tymerlachsoni</i>), sampling a 4-h window from twilight each night for two lunar cycles. Our objectives were to identify suitable call types for monitoring, evaluate a user-friendly automated call detection algorithm, assess temporal variation in vocal activity, and examine how environmental variables and moon illumination influence vocal activity. Automated call detection found an estimated 38% of all target calls but generated a high rate of false positives (96%). Among three call types, “ouah” calls were common and had the highest detection rate (51%), making them suitable target calls. Call rates were highest in the fourth hour following twilight, increased with temperature and moon illumination, and decreased during rainfall. We also observed variation in vocal activity between recording dates and sites, highlighting the need for sufficient temporal and spatial replication.

In non-human primates, males are frequently identified as the perpetrators. Classical studies categorized behaviors like “abuse”, “fatal neglect”, “kidnapping”, and “aunting to death” as forms of infanticide when they resulted in infant death. However, in more recent literature, some of these behaviors are excluded from classifications of infanticide without clear justification, particularly those involving female-related lethal actions. Therefore, we conducted a systematic review spanning 54 years to investigate potential sex biases in primate infanticide literature. Our findings show that female actions leading to infant death are often labeled with terms like “abuse” and “fatal neglect”. In contrast, similar male behaviors are consistently classified as infanticide. As a result, infanticide by non-human primate females has been systematically underreported. Classifying all lethal behaviors by females toward infants as infanticide eliminates the sex difference in the frequency of such acts. Our study shows that being consistent with the original definition of infanticide for non-human primates provides a more accurate understanding of infanticide in these animals. Thus, we strongly recommend adhering to the infanticide definition, which integrates the recorded behaviors into established theoretical frameworks, enabling more comprehensive discussions of primate infanticidal behavior.</p>","PeriodicalId":7662,"journal":{"name":"American Journal of Primatology","volume":"88 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2026-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13006818/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147497298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Weight and health records from seven research institutions across the USA were used to build models of body weight by age. Linear and Box-Cox Power Exponential (BCPE) distribution models, which have been adopted from the World Health Organization's methods, were compared to find the best fit of the models. Resultant weight percentiles and growth velocity charts were provided from the best-fit model ranked by generalized Akaike's information criterion. Multiparameter models with the BCPE distribution fit the data better than linear models with normal distributions. The assumption that infant macaque growth is linear was challenged by our findings; growth rates appear to change over the first year of life for infant macaques. Growth standards were integrated into centile charts and a computer application in MS Excel to provide user-friendly weight-for-age percentile charts to access and analyze macaque growth data. The new growth standards provide a unified reference that best represents normal physiological growth for all infant rhesus and pigtail macaques from birth through the first year of life.

Most SDMs exhibited moderate to high discriminatory ability, indicated by a test AUC &gt; 0.7, with the SPM displaying the highest level of consistency. Thermal variables were predominant for the ASM and NPM; temperature seasonality was the primary factor for the RSM and STM, while precipitation influenced the SPM distribution. Anthropogenic factors, particularly artificial light at night (ALAN), significantly impacted the LTM. Hierarchical clustering revealed three distinct clusters. The HQ assessments indicated that the SPM and STM were associated with high-quality, natural forest habitats, whereas the LTM and RSM were primarily correlated with human-modified landscapes.
