Dataset: geographical location of areas occurring Peltogyne gracilipes (Leguminosae) individuals in ecotone forests, State of Roraima, northern Brazilian Amazon

The dataset provides information on points of occurrence of Peltogyne gracilipes (a endemic tree species; Leguminosae) in an area of ~ 450,000 ha, with the geographic center of Maracá Island and its surroundings, State of Roraima, northern Brazilian Amazon (https://data.mendeley.com/datasets/2j354jtddx/2; https://data.mendeley.com/datasets/ctv52cbkp8/2). The points of occurrence of P. gracilipes (135 points) were collected with GPS, indicating the areas of presence / absence of the species. Fieldworks were carried out in the eastern and central areas of Maracá Island (12/14/2018 and 27-28/02/2019), and close to the Vila Trairão (12/17/2018) and Vila Paredão (28 / 01/2019). All of them are natural forest areas where P. gracilipes occurs. The dataset consists of four files: (i) study_site - a figure indicating the location of the study area; (ii) occurrence_p-gracilipes_maracá - geographic location (lat / long - WGS84 - UTM - 20N) of the points of occurrence of P. gracilipes on Maracá Island; (iii) occurrence_p-gracilipes_paredão - geographical location (lat / long - WGS84 - UTM - 20N) of the points of occurrence of P. gracilipes in Vila Paredão; (iv) occurrence_p-gracilipes_trairão - geographical location (lat / long - WGS84 - UTM - 20N) of the points of occurrence of P. gracilipes in Vila Trairão. The current dataset was supported by the projects (i) SavFloRR - Ecologia e manejo dos recursos naturais de ecossistemas de savanas e florestas de Roraima (PPI INPA 015/122), and (ii) Crescimento e mortalidade de árvores em florestas ecotonais de Roraima: efeito das condicionantes ambientais e da variabilidade climática (Proc.

本数据集收录了特定树种Peltogyne gracilipes（一种特有树种；豆科）在约45万公顷区域内的发生地点信息，该区域以马拉卡岛及其周边地区为中心，位于罗赖马州，巴西北部亚马逊地区（https://data.mendeley.com/datasets/2j354jtddx/2; https://data.mendeley.com/datasets/ctv52cbkp8/2）。P. gracilipes的发生地点（共135个）通过GPS采集，标示了该物种的分布与未分布区域。实地调查于马拉卡岛的东部和中部地区（2018年12月14日及2019年2月27日至28日）以及维拉特拉伊昂（2018年12月17日）和维拉帕雷阿翁（2019年1月28日）附近进行。所有地点均为P. gracilipes自然林分布区。数据集包含四个文件：（i）研究区域图，展示了研究区域的地理位置；（ii）马拉卡岛P. gracilipes发生地点，记录了该物种在马拉卡岛上的发生地点的地理坐标（纬度/经度 - WGS84 - UTM - 20N）；（iii）维拉帕雷阿翁P. gracilipes发生地点，记录了该物种在维拉帕雷阿翁的地理坐标（纬度/经度 - WGS84 - UTM - 20N）；（iv）维拉特拉伊昂P. gracilipes发生地点，记录了该物种在维拉特拉伊昂的地理坐标（纬度/经度 - WGS84 - UTM - 20N）。当前数据集得到了以下项目的支持：（i）SavFloRR项目——罗赖马州草原和森林自然资源的生态学与管理（PPI INPA 015/122），以及（ii）罗赖马州生态过渡带森林中树木的生长与死亡率：环境条件和气候变化的影响（CNPq项目号403591 / 2016-3）。巴西高等教育人员能力提升协调委员会（CAPES）支持了E.H.S.的研究。PELD项目为W.R.S.提供了奖学金（CNPq / CAPES / FAPs / BC-Fundo Newton；项目号N. 441575 / 2016-1）。巴西国家科学技术发展委员会（CNPq）为R.I.
