This general pattern calls for a understanding on diversity, and how competition can act as its ``engine\u0022. I explore sustainability of diversity, using model systems from biology. Taking the starting point in phage-bacteria ecosystems, I will describe how standard predator-prey equations can be used to quantify how phages may boost bacterial diversity. With inspiration from Lichen growing on rocks, I subsequently introduce a simple model for speciation through self organized spatial barriers. Overall my talk explore ways that existing may species support emerging species by repeated use of the competitors competitor.\u003C\/p\u003E\u003Cp\u003EReferences:\u003C\/p\u003E\u003Cp\u003EJ. O.
