Isotopic data for: Reconstructing the last foraging decisions of an iconic jaguar illuminates the sources of human-wildlife conflicts.AbstractHuman-wildlife conflicts led to the death of Máscara, one of the last jaguars in the fragmented landscapes of the Atlantic Forest. Stable isotope (δ13C and δ15N) analyses of his whiskers revealed a predominant reliance on native prey (76%) but with periods of increased domestic prey predation. This challenges the narrative of jaguars as livestock specialists within periods of jaguar-human conflicts. Instead, results highlight the jaguar´s trophic flexibility and preference for native prey. These findings emphasize the critical need for conservation strategies that integrate prey availability, jaguar behavior, and conflict mitigation to ensure coexistence in fragmented landscapes.相关同位素数据集：重现一头标志性美洲虎的末次觅食决策以阐明人兽冲突成因 摘要 人兽冲突导致了"面具"（Máscara）的死亡，它是大西洋森林破碎化景观中最后幸存的美洲虎个体之一。对其胡须开展的稳定同位素（stable isotope）分析（δ¹³C与δ¹⁵N比值分析）显示，该个体主要依赖本土猎物（占比76%），但也曾存在一段家畜捕食比例升高的时期。这一发现挑战了"美洲虎在人兽冲突时期专以家畜为食"的主流叙事。研究结果反而凸显了美洲虎的营养生态位灵活性以及对本土猎物的偏好。上述结论强调，亟需制定整合猎物可获得性、美洲虎行为与冲突缓解策略的保护方案，以保障破碎化景观中的人兽共存。
