We examined high light (HL) adapted <i>Prochlorococcus<\/i> communities across spatial and temporal environmental gradients in the Pacific Ocean to determine the ecological drivers of population structure and diversity across taxonomic ranks. We show that the <i>Prochlorococcus<\/i> community has the highest diversity at low latitudes, but seasonality driven by temperature, day length and nutrients adds complexity. At finer taxonomic resolution, some \u2018sub-ecotype\u2019 clades have unique, cohesive responses to environmental variables and distinct biogeographies, suggesting that presently defined ecotypes can be further partitioned into ecologically meaningful units. Intriguingly, biogeographies of the HL-I sub-ecotypes are driven by unique combinations of environmental traits, rather than through trait hierarchy, while the HL-II sub-ecotypes appear ecologically similar, thus demonstrating differences among these dominant HL ecotypes. Examining biodiversity across taxonomic ranks reveals high-resolution dynamics of <i>Prochlorococcus<\/i> evolution and ecology that are masked at phylogenetically coarse resolution. Spatial and seasonal trends of <i>Prochlorococcus<\/i> communities suggest that the future ocean may be comprised of different populations, with implications for ecosystem structure and function.<\/p>\n<p><a href=\"http:\/\/dx.doi.org\/10.1038\/ismej.2015.244\"><span class=\"vcard\"><span class=\"author fn\">Larkin AA<\/span><\/span>, <span class=\"vcard\"><span class=\"author fn\">Blinebry SK<\/span><\/span>, <span class=\"vcard\"><span class=\"author fn\">Howes C<\/span><\/span>, <span class=\"vcard\"><span class=\"author fn\">Lin Y<\/span><\/span>, <span class=\"vcard\"><span class=\"author fn\">Loftus SE<\/span><\/span>, <span class=\"vcard\"><span class=\"author fn\">Schmaus CA<\/span><\/span>, <span class=\"vcard\"><span class=\"author fn\">Zinser ER<\/span><\/span> and <span class=\"vcard\"><span class=\"author fn\"><strong>Johnson ZI<\/strong> (2016). <\/span><\/span>Niche partitioning and biogeography of high light adapted <em>Prochlorococcus<\/em> across taxonomic ranks in the North Pacific.
