Hypothesis
Do viruses exhibit trade-offs between survival and reproduction similar to other organisms?
Conclusion
Viruses experience trade-offs between survival and reproduction, with rapid reproducers suffering higher mortality outside their host.
Supporting Evidence
- Coliphages experience life history trade-offs similar to other organisms.
- Rapid reproducers have higher mortality rates outside their host.
- Decay rates are linked to the density of the packaged DNA.
Takeaway
This study shows that viruses, like living things, have to balance how quickly they reproduce with how long they can survive.
Methodology
The researchers measured decay and multiplication rates of 16 coliphage strains in E. coli cultures.
