Putting the fun back in functional response.
In the DeLong lab, we study eco-evolutionary interactions involving body size, temperature, trait variation, and energetics. We are taxonomically broad and work on viruses, bacteria, algae, protozoans, crustaceans, hydra, arachnids, herps, mammals, birds, and the global human population. We like theory. We do experiments. But most of all, we like theory-data reckoning.
We are currently looking for amazing new graduate students. Is that you?

Lab News
August 2019 - Miranda's temperature dependent benefits of symbiosis paper is now published. See it here.
