ASSESSING DATA GAPS IN BACTERIAL DIVERSITY KNOWLEDGE: A GLOBAL SYNTHESIS OF FRESHWATERS
Freshwaters account for 0.8% of Earth’s surface area, yet support ~10% of all known species making them disproportionately biodiverse. Modern molecular techniques have recently begun to reveal microbial diversity, and we hypothesize that biogeographic knowledge of this diversity is incomplete. To identify biogeographic gaps in microbial diversity knowledge, we conducted a literature review of freshwaters (streams, lakes, and wetlands) in which microbial diversity have been sampled using molecular techniques that either identify microbial taxa or describe their genetic diversity. We georeferenced all survey locations and used a geographic information system to identify gaps in survey coverage along climatic gradients and among freshwater ecoregions. We compiled 3,000 georeferenced survey locations reported from >600 studies. Climatic gaps in survey coverage projected onto geographic coordinate space, indicate survey coverage is fair for temperate regions but lacking in the highly biodiverse tropics and the arctic. Furthermore, only ~15% (n=64) out of the 426 freshwater ecoregions have been surveyed for microbial diversity. These results are likely due to proximity to research institutions in developed countries but necessitate expanding microbial biodiversity surveying efforts to underrepresented regions, particularly in the Neotropical, Indomalaya, and Antarctic biogeographic realms.
