摘要
Background: The growth-rate of an organism is an important phenotypic trait, directly affecting its ability to survive in a given environment. Here we present the first large scale 計算 study of the association between ecological strategies and growth rate across 113 細菌l 物種, occupying a variety of metabolic habitats. Genomic data are used to reconstruct the 物種' metabolic 網絡s and habitable metabolic environments. These reconstructions are then used to investigate the typical ecological strategies taken by organisms in terms of two basic 物種-specific measures: metabolic variability - the ability of a 物種 to survive in a variety of different environments; and co-habitation score vector - the distribution of other 物種 that co-inhabit each environment. Results: We find that growth rate is significan
