Freshwater fish species distribution in Spain

Database containing information on 40 freshwater fish species distribution across Spain at 1km grid cell resolution 1. Main file: Species_distribution_UTM_prob1000.csv The information was obtained through the development of Species Distribution Models using BIOMOD 2 (Thuiller et al. 2009) calibrated and validated on the most complete databases on fish occurrences across Spain. The database contains in the rows all UTM1x1 km within the river network, as defined by Spanis Government (Ministerio para la Transición Ecológica), and for each species includes information on the habitat suitability derived from our models (ranging from 1-1000, being 1 low habitat suitability and 1000 high habitat suitability). The projections of habitat suitability values were restricted to the hidrological basins within the natural distribution range for each species (i.e., in the hidrological basins where there was at least one presence occurence of the fish species). The hidrological basin used can be found here: https://www.miteco.gob.es/es/cartografia-y-sig/ide/descargas/agua/demarcaciones-hidrograficas-phc-2015-2021.aspx For more information about the models, see: Lanzas et al., 2022 2. Species_code_information.csv included the relation between the code used in the main database and scientific name of the species 3. UTM zip file Shapefile with the grid cells.

本数据集收录西班牙境内40种淡水鱼类在1km网格单元下的分布信息。1. 主文件为Species_distribution_UTM_prob1000.csv：数据基于针对西班牙最全鱼类出现数据库构建并验证的物种分布模型生成，模型采用BIOMOD 2（Thuiller等，2009）。数据集的行代表西班牙生态转型部（Ministerio para la Transición Ecológica）定义的河网范围内所有1×1km UTM（Universal Transverse Mercator，通用横轴墨卡托）网格单元，每个物种对应一栏由本模型生成的栖息地适宜性评分（分值区间为1~1000，其中1代表低栖息地适宜性，1000代表高栖息地适宜性）。栖息地适宜性的投影范围被限定在各物种自然分布区内的水文流域（即至少存在该鱼类物种1次出现记录的水文流域）。所用水文流域数据可从以下链接获取：https://www.miteco.gob.es/es/cartografia-y-sig/ide/descargas/agua/demarcaciones-hidrograficas-phc-2015-2021.aspx。如需了解模型详情，可参考Lanzas等，2022。2. Species_code_information.csv：包含主数据库中使用的物种代码与物种学名的对应关系。3. UTM压缩包：为包含网格单元的矢量形状文件（Shapefile），该数据也可通过以下链接获取：https://www.miteco.gob.es/es/biodiversidad/servicios/banco-datos-naturaleza/informacion-disponible/bdn-cart-aux-descargas-ccaa.html。
