Liana species of the Barro Colorado Island 50-ha plot 2007 and 2017 censuses

Overview Lianas are a common and diverse plant growth form in tropical forests, where they add considerably to the vascular plant diversity. Lianas contribute approximately 25% of the woody vascular plant species diversity in tropical forests (Gentry 1991, Schnitzer & Bongers 2002), with liana diversity varying systematically with forest mean annual rainfall and rainfall seasonality (Schnitzer 2005, 2018, Swaine & Grace 2007, DeWalt et al. 2010, 2015, Parolari et al. 2020). However, liana taxonomy and diversity have been described for relatively few tropical forest communities, thus the proportion of diversity that lianas contribute and how this diversity varies among forests is poorly understood. Here we describe and release the species present in the 2007 and 2017 liana censuses of the Barro Colorado Island, Panama (BCI) 50-ha plot. Our liana species dataset includes the current and former family, genus, species, and authority for all liana stems 1 cm diameter or larger that were rooted within the BCI 50-ha plot in either of the 2007 or 2017 censuses. Lianas were identified in the forest during the 2007 and 2017 censuses (Schnitzer et al. 2012, 2015, 2021, Schnitzer & DeFilippis 2024). In 2023, we compared our species list to the Plants of the World Online, a global list compiled by Kew Gardens to ensure that our nomenclature was consistent with the most recent taxonomic changes (see Schnitzer et al. 2024). Methods used for the liana census study were published in Gerwing et al. 2006 and Schnitzer et al. 2008; see also Parren et al. 2005, Schnitzer et al. 2006). We found a total of 178 species distributed among 117,100 rooted individuals (1 cm diameter or larger, excluding clonal stems) that were present in either the 2007 or 2017 liana censuses of the BCI 50-ha plot. We were able to positively identify > 98% of these stems to species (Schnitzer et al. 2012, 2021). Liana species contributed 35% of the woody species (lianas, trees, and shrubs 1 cm diameter or larger) using the tree and shrub data from the 2015 tree census (Condit et al. 2019). This liana species list, in combination with the spatially explicit liana and tree stem datasets (Condit et al. 2019, 2020, Schnitzer & DeFilippis 2024) provides a unique opportunity to test conceptual questions on how lianas and trees coexist in tropical forests (e.g., Schnitzer 2018, DeFilippis et al. in review, Medina-Vega et al. in review, Mello et al. in review). We welcome opportunities to collaborate with research groups interested in using this dataset; however, the data are free to be used with no restrictions other than citing this data paper and acknowledging NSF grants DEB-0613666 and IOS 15-58093, which funded the 2007 and 2017 liana censuses.

概述
木质藤本（Lianas）是热带森林中常见且多样的植物生长型，对维管植物多样性贡献显著。在热带森林中，木质藤本约占木本维管植物物种多样性的25%（Gentry 1991，Schnitzer & Bongers 2002），其多样性随森林年平均降雨量和降雨季节波动呈现系统性差异（Schnitzer 2005、2018，Swaine & Grace 2007，DeWalt et al. 2010、2015，Parolari et al. 2020）。然而，目前仅对少数热带森林群落开展了木质藤本分类学与多样性研究，因此木质藤本贡献的物种多样性比例，以及其多样性在不同森林间的变异规律仍有待阐明。本研究整理并发布了巴拿马巴罗科罗拉多岛（Barro Colorado Island, BCI）50公顷样地2007年与2017年两次木质藤本普查中的物种数据。本木质藤本物种数据集涵盖了2007年或2017年普查中，所有扎根于BCI 50公顷样地内、直径≥1厘米的木质藤本茎干的当前与曾用分类学地位，包括科、属、种及命名人信息。2007年与2017年的森林藤本普查鉴定工作由Schnitzer团队于2012、2015、2021年及Schnitzer & DeFilippis 2024年完成。2023年，我们将本物种名录与英国皇家植物园（邱园，Kew Gardens）编制的全球植物名录《世界在线植物》（Plants of the World Online）进行比对，以确保分类命名符合最新的分类学修订（详见Schnitzer et al. 2024）。本藤本普查研究采用的方法已发表于Gerwing et al. 2006与Schnitzer et al. 2008；另可参考Parren et al. 2005，Schnitzer et al. 2006。本研究共记录到178个物种，对应117100株直径≥1厘米的扎根茎干（排除克隆茎干），所有个体均出现在2007年或2017年的BCI 50公顷样地藤本普查中。其中超过98%的茎干可被准确鉴定到物种水平（Schnitzer et al. 2012、2021）。结合2015年树木普查的乔灌木数据（Condit et al. 2019），木质藤本物种占直径≥1厘米的木本物种（藤本、乔木与灌木）总数的35%。本木质藤本物种名录结合空间显性的藤本与乔木茎干数据集（Condit et al. 2019、2020，Schnitzer & DeFilippis 2024），为检验热带森林中木质藤本与乔木共存的相关理论问题提供了独特的研究契机（例如Schnitzer 2018，DeFilippis et al. 待刊，Medina-Vega et al. 待刊，Mello et al. 待刊）。我们欢迎有兴趣使用本数据集的研究团队开展合作；本数据集可免费使用，但需引用本数据论文，并致谢资助2007年与2017年藤本普查的美国国家科学基金会（NSF）项目DEB-0613666与IOS 15-58093。
