Reconstructing Sakhalin Taimen Parahucho perryi Historical Distribution and Identifying Causes for Local Extinctions

摘要: Abstract The Sakhalin taimen Parahucho perryi is an endangered salmonid with a natural range limited to the Russian Far East and Japan. We constructed classification tree determine environmental factors shaping historical global distribution of this species then predicted its potential geographic range. was most strongly influenced by spatial autocorrelation term, indicating that it highly contiguous. Large drainage basins low topographic relief large floodplains had higher probability occurrence. boundary delineated mean monthly precipitation within 54–96 mm. presence in many where has never been recorded. also modeled status 48 populations Japan, possible classify them into three categories: currently stable (7), (5), extinct (36). significant factor differentiating 12 extant ...
