Harmonized wood density data for Central Amazon species in the BIONTE experimental area in Manaus, Brazil

BIONTE (BIOmass and NuTrient Experiment) is a selective logging experiment established at the Experimental Station of Tropical Forestry (EEST, aka “ZF2”) field research station in the mid 1980s in the central Amazon (Higuchi et al. 1997, Amaral et al. 2019). The main data related to BIONTE are available as a separate dataset (Lima et al. 2022). Only species identified within the BIONTE plots were included in this dataset. Wood density, expressed in g cm-3, was collated from multiple sources that were integrated to compose the wood density for BIONTE. The starting point used was wood density data available from Chave et al. (2006), which was then adapted by Marra et al. (2016) and Marra et al. (2018). We also included data collected and synthesized by Ramírez-Méndez (2018) and Gimenez et al.(2021), who combined local estimates of wood density at the site with other sources collected in the Central Amazon. Data are included in .csv files, while BIONTE_WD_headers.txt provides descriptions of data file headers. This dataset was originally published on the NGEE Tropics Archive and is being mirrored on ESS-DIVE for long-term archival生物量与养分试验（BIONTE，即BIOmass and NuTrient Experiment）是一项选择性采伐试验，于20世纪80年代中期设立于亚马逊中部地区的热带林业试验站（EEST，又称“ZF2”）野外研究站（Higuchi等，1997；Amaral等，2019）。与BIONTE相关的核心数据集已作为独立数据集发布（Lima等，2022）。本数据集仅纳入了BIONTE样地内已鉴定的物种。本数据集的木材密度（单位为g cm⁻³）数据整合自多源资料，以构建BIONTE试验的木材密度数据集：其初始基准数据源为Chave等（2006）发布的木材密度数据，后续经Marra等（2016）与Marra等（2018）进行了适配调整；此外还纳入了Ramírez-Méndez（2018）及Gimenez等（2021）收集整合的相关数据，二者均将该试验站点的本地木材密度估算值与亚马逊中部地区其他来源的资料进行了结合。数据集以逗号分隔值（.csv）格式存储，BIONTE_WD_headers.txt文件用于说明各数据文件的表头信息。本数据集最初发布于NGEE Tropics档案馆，目前已在ESS-DIVE平台进行镜像备份以实现长期归档。
