DOI:
doi:10.5061/dryad.m010p
摘要:
Previous analyses of evolutionary patterns, or modes, in fossil lineages have focused overwhelmingly on three simple models: stasis, random wal
Data from: Free vibration analysis of transmission lines based on the dynamic stiffness method

关键词:
Microbial Biology;Plasmid biology;Evolutionary Theory;antibiotic resistance;Evolutionary Medicine;Mutation
DOI:
doi:10.5061/dryad.p745m
摘要:
. Previous work has shown that the cost of resistance is highly variable, but the underlying causes remain poorly understood. Here, we use a meta-analysis
