Abstract

Developing standardized methodology to allow efficient and cost‐effective ecological data collection, particularly at scale, is of critical importance for understanding species' declines. Remote camera networks can enable monitoring across large spatiotemporal scales and at relatively low researcher cost, but manually analysing images and extracting biologically meaningful data is time‐consuming. Citizen science image analysis could reduce researcher workload and increase output from large datasets, while actively raising awareness of ecological and conservation issues. Nevertheless, testing the validity of citizen science data collection and the retention of volunteers is essential before integrating these approaches into long‐term monitoring programmes. In this study, we used data from a Zooniverse citizen science project, Seabird Watch, to investigate changes in breeding timing of a globally declining seabird species, the Black‐legged Kittiwake Rissa tridactyla. Time‐lapse cameras collected >200 000 images between 2014 and 2023 across 11 locations covering the species' North Atlantic range (51.7°N–78.9°N), with over 35 000 citizen science volunteers ‘tagging’ adult and juvenile Kittiwakes in images. Most volunteers (81%) classified images for only a single day, and each volunteer classified a median of five images, suggesting that high volunteer recruitment rates are important for the project's continued success. We developed a standardized method to extract colony arrival and departure dates from citizen science annotations, which did not significantly differ from manual analysis by a researcher. We found that Kittiwake colony arrival was 2.6 days later and departure was 1.2 days later per 1° increase in latitude, which was consistent with expectations. Year‐round monitoring also showed that Kittiwakes visited one of the lowest latitude colonies, Skellig Michael (51.8°N), during winter, whereas birds from a colony at similar latitude, Skomer Island (51.7°N), did not. Our integrated time‐lapse camera and citizen science system offers a cost‐effective means of measuring changes in colony attendance and subsequent breeding timing in response to environmental change in cliff‐nesting seabirds. This study is of wide relevance to a broad range of species that could be monitored using time‐lapse photography, increasing the geographical reach and international scope of ecological monitoring against a background of rapidly changing ecosystems and challenging funding landscapes.
利用公民科学图像分析测量海鸟物候学
开发标准化方法,以高效、经济地收集生态数据,尤其是大规模数据,对于了解物种的衰退至关重要。远程摄像网络可以实现大时空尺度的监测,而且研究人员的成本相对较低,但人工分析图像和提取有生物意义的数据非常耗时。公民科学图像分析可以减少研究人员的工作量,增加大型数据集的产出,同时积极提高人们对生态和保护问题的认识。不过,在将这些方法纳入长期监测计划之前,测试公民科学数据收集的有效性和留住志愿者至关重要。在本研究中,我们利用 Zooniverse 公民科学项目 "海鸟观察 "的数据,调查了全球正在减少的海鸟物种--黑腿海鸟 Rissa tridactyla 的繁殖时间变化。从 2014 年到 2023 年,延时摄影机在该物种的北大西洋分布区(51.7°N-78.9°N)的 11 个地点收集了 200,000 张图片,超过 35,000 名公民科学志愿者在图片中 "标记 "了成年和幼年海鸟。大多数志愿者(81%)只对图片进行了一天的分类,每位志愿者分类图片的中位数为五张,这表明志愿者的高招募率对项目的持续成功非常重要。我们开发了一种标准化方法,从公民科学注释中提取鸟群到达和离开的日期,该方法与研究人员的人工分析没有显著差异。我们发现,纬度每上升 1°,海龟群到达时间推迟 2.6 天,离开时间推迟 1.2 天,这与预期一致。全年监测还显示,海龟鸟在冬季会光顾纬度最低的一个栖息地斯凯利格-迈克尔岛(北纬 51.8 度),而纬度相近的一个栖息地斯科默岛(北纬 51.7 度)的海龟鸟则不会光顾。我们的综合延时摄影机和公民科学系统提供了一种具有成本效益的方法,可以测量崖上筑巢的海鸟在环境变化时栖息地出勤率和随后繁殖时间的变化。这项研究对可使用延时摄影监测的广泛物种具有广泛的意义,在生态系统迅速变化和筹资环境具有挑战性的背景下,扩大了生态监测的地理范围和国际范围。

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
