入侵物种威胁着生物多样性和生态系统的功能。我们开发了一种创新的实验方法，将生物启发的机器人技术，时间序列分析和计算机视觉相结合，以建立非致命压力对食蚊鱼（Gambusia holbrooki）生态和进化的影响的详细资料-一种全球性害虫。我们发现，短暂暴露于机器人捕食者改变食蚊鱼的行为，增加恐惧和压力反应，并减轻影响的本地蝌蚪（Litoria moorei）在因果关系的方式食蚊鱼。捕食风险的影响，从机器人结转到日常活动和摄食率的食蚊鱼周后曝光，导致体重减轻，体型的变化，并减少生育能力的两个性别损害生存，繁殖和生态成功。我们利用食蚊鱼的进化反应来减少捕食风险在生物控制实践中被忽视，并为在生态学和进化研究中广泛使用最先进的机器人技术提供科学基础。机器人捕食者能揭示入侵物种和有害物种的脆弱性吗？我们的捕食者选择性地攻击入侵鱼类以保护本地两栖动物来自机器人的压力会损害入侵者的行为，健康和繁殖我们为机器人技术在生态学，进化和生物控制研究中开辟了新的前沿生物科学，生态学，动物学
Invasive species threaten biodiversity and ecosystem functioning. We develop an innovative experimental approach, integrating biologically inspired robotics, time-series analysis, and computer vision, to build a detailed profile of the effects of non-lethal stress on the ecology and evolution of mosquitofish (Gambusia holbrooki)—a global pest. We reveal that brief exposures to a robotic predator alter mosquitofish behavior, increasing fear and stress responses, and mitigate the impact of mosquitofish on native tadpoles (Litoria moorei) in a cause-and-effect fashion. Effects of predation risk from the robot carry over to routine activity and feeding rate of mosquitofish weeks after exposure, resulting in weight loss, variation in body shape, and reduction in the fertility of both sexes—impairing survival, reproduction, and ecological success. We capitalize on evolved responses of mosquitofish to reduce predation risk—neglected in biological control practices—and provide scientific foundations for widespread use of state-of-the-art robotics in ecology and evolution research. Can robotic predators reveal the vulnerabilities of invasive and pest species? Our predator selectively targets invasive fish to protect native amphibians Stress from the robot compromises behavior, health, and reproduction of invaders We open new frontiers for robotics in ecology, evolution, and biocontrol research Biological Sciences, Ecology, zoology
