Species and habitats - Zeus faber - All ages - IBTS Multi-annual abundance in January (1980-1990, 1991-2000, 2001-2010)

Due to data paucity, the interpolated maps were computed using all the data available over three periods : 1980-1990, 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.由于数据稀缺，本研究采用1980-1990年、1991-2000年及2001-2010年三个时段的全部可用数据，计算得到插值地图。生物数据以丰度形式表征，包括个体数量或密度值（单位：个/平方千米），且均需通过log10(x+1)变换进行对数转换。
