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.<br>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.

这些数据与即将发表在《生态学与进化》[ISSN:2045-7758]的一篇论文相关。"All data_mn_final.csv"为雾网数据集，"All data_pc_final.csv"为点计数数据集。数据来源的研究列表已包含在内：雾网研究对应"List of studies_mn"，点计数研究对应"List of studies_pc"。<br>数据来源于30项研究（19项采用雾网法（mist-netting），11项采用点计数法（point-count）），这些研究包含选择性采伐林与原始老龄林中鸟类物种的丰度或捕获率信息。通过Web of Science在线数据库检索相关研究，关键词为["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]，并进一步限定为[tropic*]和["mist-net" OR "point-count"]，共得到80156项研究。随后筛选出主题涉及环境科学、生态学、林业、动物学及生物多样性保护的研究，剩余525项。此外，通过Google Scholar补充两次检索：检索1关键词为"selective logging"、bird*、avian、aves、mass、abundance、number、"capture rate"、density、"mist-net*"、"point-count*"、tropic*；检索2关键词为"regenerating forest"、bird*、avian、aves、mass、abundance、number、"capture rate"、density、"mist-net*"、"point-count*"、tropic*。检索1得到774项研究，检索2得到215项研究。去重后共1395项研究，经标题筛选剩余676项，再经摘要筛选剩余211项。所有检索于2019年4月4日至18日进行。在211项研究中，全文筛选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°之间）开展；（ii）在郁闭林内开展；（iii）采用雾网法或点计数法采样鸟类；（iv）同时提供选择性采伐林与原始老龄林中物种特异性丰度或捕获率估计；（v）雾网与点计数数据集（若同时存在）可分离。最终纳入30项研究（19项雾网研究、11项点计数研究）。对于有质量数据的研究直接提取，无质量数据或部分物种缺失质量数据的研究，参考《Dunning鸟类体重CRC手册》（2008）及《世界鸟类手册（活版）》（del Hoyo等，2017）补充。其中两项研究（Wunderle等，2006；Hawes等，2008）因包含不同生境数据且各生境鸟类群落独特，数据被拆分单独分析，最终得到21项独立的雾网研究。
