Protists in the polar regions: comparing occurrence in the Arctic and Southern oceans using pyrosequencing
In the ongoing discussion of the distribution of protists, whether they are globally distributed or endemic to one or both of the polar regions is the subject of heated debate. In this study, we compared next-generation sequencing data from the Arctic and the Southern oceans to reveal the extent of...
