The vast unknown microbial biosphere.
The desire to know how many living beings there are on the planet has been a permanent obsession of biologists. Many inventories have been done, especially with large animals and plants, since naturalists began modern taxonomy in the 18th century. But there is the feeling that we are missing a large part of the diversity of microorganisms. How large this ignorance is, however, is a matter of de...
متن کاملEcology of the rare microbial biosphere of the Arctic Ocean.
Understanding the role of microbes in the oceans has focused on taxa that occur in high abundance; yet most of the marine microbial diversity is largely determined by a long tail of low-abundance taxa. This rare biosphere may have a cosmopolitan distribution because of high dispersal and low loss rates, and possibly represents a source of phylotypes that become abundant when environmental condi...
متن کاملMicrobiome, demystifying the role of microbial communities in the biosphere
The backstory to the motivation for launching Microbiome is a tale of two subdisciplines finding philosophical common ground fueled by substantial technological advancements in DNA sequencing and analysis. Until recently it was possible to neatly divide microbiology into two largely exclusive subdisciplines: clinical microbiology and environmental microbiology. Guided by Koch's postulates for m...
متن کاملMicrobial Ecology: Finding Structure in the Rare Biosphere
Protists (unicellular eukaryotes) play important roles in marine ecosystems but are tremendously diverse and many remain uncharacterized. Deep-sequencing of a universal marker gene has helped resolve community composition patterns among rare and abundant protistan sequence groups in coastal European waters.
متن کاملA molecular view of microbial diversity and the biosphere.
Over three decades of molecular-phylogenetic studies, researchers have compiled an increasingly robust map of evolutionary diversification showing that the main diversity of life is microbial, distributed among three primary relatedness groups or domains: Archaea, Bacteria, and Eucarya. The general properties of representatives of the three domains indicate that the earliest life was based on i...
