In this talk I’ll describe two recent research projects. In the first, I ask how temperature sensitivities are altered by resource limitation, at both the individual and ecosystem level. I show how we can ‘scale up’ from individuals to ecosystems, by considering how traits change due to competition across environments. In the second project, I ask what drives variation in life history traits of viruses that infect phytoplankton. I find that traits of the host (genome size and growth rate) can explain traits of the virus (burst size and latent period), and I analyze an eco-evolutionary model to explore the underlying mechanisms.
