The fossils provide the earliest direct evidence for avian frugivory and suggest that seed dispersal by neornithine (crown group) birds occurred earlier and was more extensive than currently thought. For the first time, we report seeds in the stomach content of stem group Trogoniformes, which today are important seed dispersers in the New World tropics. Other birds belong to the Galliformes, Gruiformes (Messelornithidae), Coliiformes, Coraciiformes, and the extinct taxa Halcyornithidae and Zygodactylidae. Extant Coraciiformes are predominantly carnivorous, whereas some Galliformes and Gruiformes as well as the Coliiformes today also consume fruits. All reasonably well-preserved seeds appear to be from angiosperms, including specimens identified as Rutaceae, Mastixiaceae, and Vitaceae. Unidentified seeds represent various other plant groups. Several of the arboreal birds ingested seeds of the Vitaceae. This plant family already evolved in the Late Cretaceous, whereas arboreal Neornithes did not radiate before the early Cenozoic. As such, and at least concerning arboreal birds, these fossils provide evidence for the “recruitment hypothesis”, which suggests that early Cenozoic seed dispersers exploited an existing diversity of edible fruits.</p></div>","PeriodicalId":794,"journal":{"name":"The Science of Nature","volume":"113 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00114-026-02130-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148389742","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}

How subjects perceive climatic conditions is not always well detected as it is highly subjective, depending on species, age and experience. Hence, decisions on housing rely mostly on human anthropomorphic perception. In particular, indicators of comfort and positive emotions remain poorly documented. Acoustic signals, however, offer a promising window into animals’ internal states. In the present study, we hypothesized that acoustic signals could be used to identify positive or negative perceptions of environmental conditions in horses. Horses possess a diverse acoustic repertoire and the snort produced by nostril vibration, has been identified as a likely indicator of calm, positive emotions. Over 3 weeks in early spring, acoustic production and time budget were recorded for 20 adult horses living outdoors on pasture. Meteorological conditions and pasture composition were monitored simultaneously. Results showed that snorts were the most frequent acoustic signal and that their production varied considerably across observation sessions. Snort production was highly correlated with temperature: horses produced more snorts and showed more relaxed behaviours when the temperature ranged between 15 and 20 °C. In contrast, lower temperatures around 5–8 °C were associated with more “static” behaviours (reflecting energy conservation) and less snorts. Finally, snorts were more frequent immediately after horses entered a new pasture with higher food diversity than just before leaving, when food diversity had become more restricted. These findings suggest that acoustic production may help identify the subjective perception that animals have from their environment, allowing more individualized and adapted management practices.</p></div>","PeriodicalId":794,"journal":{"name":"The Science of Nature","volume":"113 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00114-026-02113-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148350184","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}

Since the late twentieth century, earprints have occasionally been introduced as evidence in criminal investigations and court proceedings in several jurisdictions, including the Netherlands, the United Kingdom, Switzerland, and the United States. Despite these applications, the scientific validity of earprint comparison remains contested. This article presents a narrative review of the forensic, anthropological, and legal literature on earprint identification. It examines the development of earprint research from early anthropometric approaches to contemporary digital and automated comparison techniques. Particular attention is given to the anatomical basis of ear morphology, the classification of earprints, and the methodological frameworks used in forensic comparison. The review also evaluates empirical studies addressing variability in earprint deposition, examiner subjectivity, and the absence of validated statistical models for assessing evidential strength. The medico-legal implications of earprint evidence are examined through analysis of forensic casework and appellate decisions in which earprint testimony played a significant role. These cases illustrate the risks associated with the premature adoption of forensic techniques lacking standardized protocols and empirically established error rates. The review concludes that although earprints may provide investigative information and potentially corroborative evidence, current scientific limitations prevent their reliable use as independent identification evidence. Future progress requires standardized international protocols, large-scale validation studies, probabilistic interpretation frameworks, and interdisciplinary collaboration between forensic scientists, statisticians, and legal scholars.</p></div>","PeriodicalId":794,"journal":{"name":"The Science of Nature","volume":"113 4","pages":""},"PeriodicalIF":1.7,"publicationDate":"2026-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148256827","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}

Despite its recognized value, a comprehensive synthesis integrating recent advances in phytochemistry, propagation biology, and conservation genetics remains limited. This review compiles current knowledge on taxonomy, distribution, traditional uses, phytochemical composition, pharmacological activities, propagation strategies, and conservation status based on literature available up to March 2025. The species is rich in bioactive compounds, particularly pentacyclic triterpenes, flavonoids, sterols, and phenolics, which underpin its antioxidant, anti-inflammatory, antimicrobial, antidiabetic, cardioprotective, and anticancer properties. However, most studies rely on crude extracts and short term assays, with limited mechanistic, pharmacokinetic, and long-term toxicological validation. Regeneration is constrained by low seed viability, recalcitrant seed behavior, and poor natural recruitment, while vegetative propagation methods show moderate success and emerging micropropagation approaches require further validation. Increasing anthropogenic pressures and habitat degradation have led to regional population declines, highlighting the need for comprehensive genetic, demographic, and conservation assessments. Future priorities include standardized phytochemical profiling, bioassay-guided isolation, rigorous toxicological evaluation, scalable propagation protocols, and population-level genetic studies to support sustainable utilization and long-term conservation.</p></div>","PeriodicalId":794,"journal":{"name":"The Science of Nature","volume":"113 4","pages":""},"PeriodicalIF":2.1,"publicationDate":"2026-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148203605","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}
