However, it remains unclear whether there are general rules of how microbial species abundances are shaped by biotic and abiotic factors. Here we show that the ribosomal RNA gene operon (&lt;em&gt;rrn&lt;/em&gt;) copy number, a genomic trait related to bacterial growth rate and nutrient demand, decreases from the abundant to the rare biosphere in the nutrient-rich coastal sediment but exhibits the opposite pattern in the nutrient-scarce pelagic zone of the global ocean. Both patterns are underlain by positive correlations between community-level&amp;nbsp;&lt;em&gt;rrn&lt;/em&gt;&amp;nbsp;copy number and nutrients. Furthermore, inter-species co-exclusion inferred by negative network associations is observed more in coastal sediment than in ocean water samples. Nutrient manipulation experiments yield effects of nutrient availability on&amp;nbsp;&lt;em&gt;rrn&lt;/em&gt;&amp;nbsp;copy numbers and network associations that are consistent with our field observations. Based on these results, we propose a “hunger games” hypothesis to define microbial species abundance rules using the&amp;nbsp;&lt;em&gt;rrn&lt;/em&gt;&amp;nbsp;copy number, ecological interaction, and nutrient availability.</style></abstract></record></records></xml>
