Abstract

Foraging is a key driver of animal movement patterns, with specific challenges for predators which must search for mobile prey. These patterns are increasingly impacted by global changes, principally in land use and climate. Understanding the degree of flexibility in predator foraging and social strategies is pertinent to wildlife conservation under global change, including potential top-down effects on wider ecosystems. Here we propose key future research directions to better understand foraging strategies and social flexibility in predators. In particular, rapid continued advances in biologging technology are helping to record and understand dynamic behavioural and movement responses of animals to environmental changes, and their energetic consequences. Data collection can be optimised by calibrating behavioural interpretation methods in captive settings and strategic tagging decisions within and between social groups. Importantly, many species' social systems are increasingly being found to be more flexible than originally described in the literature, which may be more readily detectable through biologging approaches than behavioural observation. Integrating the effects of the physical landscape and biotic interactions will be key to explaining and predicting animal movements and energetic balance in a changing world.

摘要

觅食是动物运动模式的关键驱动因素,对必须搜寻移动猎物的捕食者来说存在特定挑战。这些模式正日益受到全球变化的影响,主要体现在土地利用和气候方面。了解捕食者觅食和社会策略的灵活程度对于全球变化背景下的野生动物保护至关重要,包括对更广泛生态系统可能产生的自上而下的影响。在此,我们提出未来关键的研究方向,以更好地理解捕食者的觅食策略和社会灵活性。特别是,生物记录技术的迅速持续进步有助于记录和理解动物对环境变化的动态行为和运动反应及其能量后果。通过在圈养环境中校准行为解释方法以及在社会群体内部和之间进行战略性标记决策,可以优化数据收集。重要的是,越来越多的物种社会系统被发现比文献中最初描述的更加灵活,通过生物记录方法可能比行为观察更容易检测到这一点。整合物理景观和生物相互作用的影响将是解释和预测不断变化的世界中动物运动和能量平衡的关键。
