Data for paper: "Mass-abundance scaling in avian communities is maintained after tropical selective logging"

These data relate to a soon to be published paper in Ecology and Evolution [ISSN: 2045-7758]. "All data_mn_final.csv" is the mist-netting dataset and "All data_pc_final.csv" is the point-count dataset. A list of studies from which these data were extracted are included: "List of studies_mn" for mist-net studies and "List of studies_pc" for point-count studies.Data were obtained from 30 studies (19 studies using mist-netting methods and 11 studies using point-count methods) that contained information on abundance or capture rate for avian species in both selectively logged forests and old-growth primary forest controls across the tropics. The online Web of Science database was used to search for studies with the keywords ["selective logging" OR forestry OR "secondary forest" OR "regenerating forest"] AND [bird* OR avian OR aves] AND [mass OR abundance OR number OR "capture rate" OR density]. This search was refined by [tropic*] and [“mist-net” OR “point-count”] resulting in 80 156 studies. We further refined the search to only include studies with topics such as environmental sciences, ecology, forestry, zoology and biodiversity conservation, leaving us with 525 studies. We then supplemented the search using two more Google Scholar searches with the keywords; search 1: "selective logging", bird*, avian, aves, mass, abundance, number, "capture rate", density, “mist-net*”, “point-count*”, tropic*; search 2: "regenerating forest, bird*, avian, aves, mass, abundance, number, "capture rate", density, “mist-net*”, “point-count*”, tropic*. Search 1 resulted in 774 studies and search 2 returned 215 studies. This left us with a total of 1514 studies and after removing duplicates, we were left with 1395 studies. Excluding studies based on title reduced the collection to 676 studies and excluding the remaining studies based on abstract resulted in 211 studies. All searches were conducted between 4th April 2019 to 18th April 2019. Of these 211 studies, studies were only included during full-text screening if they were (i) conducted in the tropics (between 23.43706°N and 23.43706°S), (ii) conducted in closed-canopy forests, (iii) used mist-netting or point-counts to sample birds, (iv) presented species-specific abundance estimates in both selectively logged forests and old-growth primary forests, and (v) mist-net and point-count datasets (if both included) could be separated. This resulted in a total of 47 studies, for one of which the author no longer had the abundance dataset, another one for which the sole author (Johns 1996) was uncontactable, and for 15 of which we did not get a response from the authors we contacted. This left us with 30 studies (19 mist-netting studies and 11 point-count studies. Where available, mass was obtained from individual studies, and for studies in which no information on mass was provided (or where masses were missing for some species), we used Dunning's CRC Handbook of Avian Body Masses (2008) and Handbook of the birds of the world alive (del Hoyo et al. 2017). The data from two of these studies (Wunderle et al. 2006; Hawes et al. 2008) were split and analysed separately as they contained data from different habitats, where each habitat type contained a distinct avian community. This resulted in 21 separate mist-netting studies.

本数据集涉及即将发表在《生态与进化》杂志（ISSN: 2045-7758）上的一篇论文。‘All data_mn_final.csv’文件为迷网捕获数据集，而‘All data_pc_final.csv’文件则为点计数数据集。所收集数据源自以下研究列表：‘List of studies_mn’（迷网研究列表）和‘List of studies_pc’（点计数研究列表）。数据采集自30项研究（其中19项采用迷网法，11项采用点计数法），这些研究涵盖了热带选择性伐木森林和原生老林控制区鸟类物种的丰度或捕获率信息。通过在线Web of Science数据库，利用关键词“[选择性伐木 OR 林业 OR 次生林 OR 更新林] AND [鸟* OR 鸟类 OR 鸽鸟] AND [质量 OR 丰度 OR 数量 OR 捕获率 OR 密度]”进行文献检索。检索过程通过添加[tropic*]和[“mist-net” OR “point-count”]进行细化，最终得到80,156项研究。进一步筛选，仅保留涉及环境科学、生态学、林业、动物学和生物多样性保护等主题的研究，筛选后剩余525项研究。随后，通过Google Scholar进行两次补充搜索，关键词分别为：搜索1：“选择性伐木”，bird*，avian，aves，mass，abundance，number，“capture rate”，density，“mist-net*”，“point-count*”，tropic*；搜索2：“更新森林”，bird*，avian，aves，mass，abundance，number，“capture rate”，density，“mist-net*”，“point-count*”，tropic*。搜索1得到774项研究，搜索2返回215项研究。总计获得1514项研究，去除重复项后，剩余1395项研究。通过标题筛选，研究集合缩减至676项，再通过摘要筛选，最终剩余211项研究。所有搜索活动均在2019年4月4日至2019年4月18日期间进行。在全文筛选过程中，仅纳入符合以下条件的研究：（i）在热带地区（北纬23.43706°至南纬23.43706°）进行，（ii）在密闭冠层森林中进行，（iii）使用迷网法或点计数法对鸟类进行采样，（iv）在选择性伐木森林和原生老林中提供物种特定的丰度估计，（v）迷网和点计数数据集（如两者均包含）能够分离。最终得到47项研究，其中一项研究因作者已无法联系而无法获取丰度数据集，另一项研究因Johns 1996年独立作者无法联系，另外15项研究因未能从联系到的作者处获得回复。最终筛选出30项研究（19项迷网研究，11项点计数研究）。在可能的情况下，从个别研究中获取了质量数据，对于未提供质量信息（或某些物种质量数据缺失）的研究，我们使用了Dunning的《鸟类体重CRC手册》（2008年）和《现存的鸟类手册》（del Hoyo et al. 2017年）。其中两项研究（Wunderle et al. 2006；Hawes et al. 2008）的数据因涉及不同生境而进行了分离分析，每个生境类型都包含独特的鸟类群落。因此，共得到21项独立的迷网研究。
