Abstract

ABSTRACT Capsule Through case studies that link changes in invertebrate populations to changes in bird populations, we suggest how climate change may increasingly impact bird populations through variation in their invertebrate prey. Aims To assess whether invertebrate and bird population declines could be linked and suggest potentially emerging climate change impacts on wildlife. Methods We draw on field experience and case studies to illustrate how potential climate change impacts on invertebrates may cascade to affect bird populations and identify some key research gaps for urgent consideration. Results We highlight four invertebrate groups which may be sensitive to the impacts of climate change and that have the potential to impact bird populations that feed on them: soil invertebrates, foliar invertebrates, aerial insects, and aquatic invertebrates. Conclusion Our ability to understand these impacts is hampered by a lack of extensive long-term monitoring data for many invertebrates, and invertebrate data collected at scales that can be related to bird populations. We call for collaboration between entomologists and ornithologists, both non-vocational and professional, to support new empirical research and long-term monitoring initiatives to better link changes in insect populations and birds to inform future decision-making. This will be particularly important to understand likely future increasing climate change pressures on birds.
无脊椎动物和鸟类数量的减少——它们是否与气候变化有关?
摘要:通过将无脊椎动物种群变化与鸟类种群变化联系起来的案例研究,我们提出了气候变化如何通过无脊椎动物猎物的变化对鸟类种群产生越来越大的影响。目的评估无脊椎动物和鸟类数量的下降是否有联系,并提出气候变化对野生动物的潜在影响。方法利用野外经验和案例研究,说明气候变化对无脊椎动物的潜在影响如何级联影响鸟类种群,并确定一些迫切需要考虑的关键研究空白。结果:土壤无脊椎动物、叶面无脊椎动物、空中昆虫和水生无脊椎动物这四种无脊椎动物可能对气候变化的影响敏感,并有可能影响以它们为食的鸟类种群。由于缺乏对许多无脊椎动物的广泛的长期监测数据,以及在可能与鸟类种群有关的尺度上收集的无脊椎动物数据,我们理解这些影响的能力受到了阻碍。我们呼吁非职业和专业昆虫学家和鸟类学家合作,支持新的实证研究和长期监测计划,以更好地将昆虫种群和鸟类的变化联系起来,为未来的决策提供信息。这对于了解未来可能增加的气候变化对鸟类的压力尤为重要。

期刊介绍: Bird Study publishes high quality papers relevant to the sphere of interest of the British Trust for Ornithology: broadly defined as field ornithology; especially when related to evidence-based bird conservation. Papers are especially welcome on: patterns of distribution and abundance, movements, habitat preferences, developing field census methods, ringing and other techniques for marking and tracking birds. Bird Study concentrates on birds that occur in the Western Palearctic. This includes research on their biology outside of the Western Palearctic, for example on wintering grounds in Africa. Bird Study also welcomes papers from any part of the world if they are of general interest to the broad areas of investigation outlined above. Bird Study publishes the following types of articles: -Original research papers of any length -Short original research papers (less than 2500 words in length) -Scientific reviews -Forum articles covering general ornithological issues, including non-scientific ones -Short feedback articles that make scientific criticisms of papers published recently in the Journal.
