Species and habitats - Buglossidium luteum - All ages - IBTS Multi-annual abundance in summer (1991-2000, 2001-2010)

Due to data paucity, the interpolated maps were computed using all the data available over two periods : 1991-2000 and 2001-2010. Biologic data have been expressed in abundance (numbers or density values (nbr/km²)) and always required to be log-transformed using a log10(x+1) transformation.鉴于数据匮乏，本次插值地图（interpolated maps）采用1991-2000年与2001-2010年两个时段的全部可用数据计算得到。生物数据以丰度形式表征，包含种群数量或密度值（单位：个/平方千米，nbr/km²），且均需通过log10(x+1)变换完成对数转换。
