- ItemFungal biogeography and the use of publicly available data for answering biogeographic questions(2019-08-21) Harris, Mathew A.; Greve, Michelle; Slippers, Bernard; Kemler, MartinMicrobes represent the majority of species on earth. Yet, our understanding of how microbes are distributed across space and through time, i.e. microbial biogeography, remains poorly understood, particularly at large (continental and global) scales. Recently, the widely adopted use of next-generation sequencing technologies and the ability to sequence microbial communities directly from environmental samples have resulted in the rapid accumulation of high-quality community datasets. These datasets are uploaded onto publicly accessible platforms, e.g. NCBI’s GenBank, and thus represent a potential source of metadata (e.g. locality records) with which to explore biogeographic patterns. DNA sequence data and linked metadata of plant-associated fungal communities were extracted from Genbank. The metadata of these samples were investigated to assess the completeness of the user-defined metadata, as well as its geographic coverage, habitat origin, plant organ of host and host identity, amongst others. While the sequence information contained on these public repositories is considered to be of high quality, the submitter-defined metadata of the samples is of a lower quality or incomplete, limiting the re-use of the high-quality sequence data. We conclude that, while microbial biogeographic studies are now, more than ever, poised to make major contributions to biogeographic theory, good quality and complete metadata are essential to maximise the value of, and allow novel insights from, DNA sequence data.
