Silica-scaled Chrysophytes of cold region

This first survey in 2009 and 2010 on silica-scaled Chrysophytes in Zhenbao Island Wetland Preserve, Northeast China, recorded 32 taxa (5 in Chrysophyceae and 27 in Synurophyceae), of which 29 were previously found in other parts of China, three species, Spiniferomonas serrata, Mallomonas transsylvanica and Synura punctulosa are new records to China. In terms of biogeography, 1 taxon is endemic, 2 bipolar, 1 northern temperate, 9 cosmopolitan, and 18 of wide distribution. The endemism of Synura punctulosa, appears due to its poor dispersal ability; lack of sampling data may also contribute its known distribution range. Spiniferomonas serrata and Mallomonas transsylvanica, two bipolar taxa, are the first report in China. More research efforts are needed for adequately understanding the distributions of this group of algae. © (2012) Trans Tech Publications, Switzerland
