McCann's lab studies the structure and function of food webs. His lab aims to understand the extent to which biodiversity influences ecological systems.
He uses a collaborative approach to develop thorough scientific experimentation that combines population, communication, and ecosystem processes.
Overall, the aim of his lab is to elucidate how humans are impacting biodiversity and ecosystem services on a large-scale.
Developing sustainable food production in the face of climate change is one of the most important challenges of our time. Sustainable global food security requires that all forms of food production, including natural resource harvesting, does not simultaneously alter the biodiversity, structure and the ecosystem services (e.g., carbon storage) we rely on.
