Phages and bacteria coexist in virtually any ecosystem, and remnants of their interactions are found in most bacterial genomes. Starting with phage-bacterial ecosystems, I will describe the use of standard predator-prey equations to quantify how phages may boost bacterial diversity, or how different bacteria may use even a single phage type to maintain this diversity. Subsequently, I will introduce a bet-hedging model aimed at quantifying the pros and cons for virulent versus temperate phage strategies. Finally I will discuss an epidemic model for phages spreading on a bacterial lawn, thereby again emphasizing the advantages of temperate phages as well as the peculiarities of the lysogenic choice of phage lambda.
