This accounts for different growth mechanisms and environmental fluctuations, leading to a generalized gamma distribution of abundance fluctuations. Our findings reveal that microbial growth is never sublinear, so they cannot endorse—at least in the microbial world—the recent proposal of this mechanism as a stability enhancer of highly diverse communities. These results have significant implications for understanding macroecological patterns and the stability of microbial ecosystems. application/octet-stream en-GB Revista: Physical Review E, Periodo: 1, Volumen: online, Número: 4, Página inicial: 044404-1, Página final: 044404-8 Instituto de Investigación Tecnológica (IIT) - Dinámica No Lineal Microbial populations hardly ever grow logistically and never sublinearly info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion info:eu-repo/semantics/openAccess Microbial Growth, Logistic Model, Macroecological Patterns, Environmental Fluctuations
