Structure and Dynamics of Highly-Dimensional Ecological Systems

Shai Pilosof, University of Chicago, Department of Ecology & Evolution
Ecological systems are inherently multi-dimensional. For example, they vary in space or time or interconnect to form networks of species networks. However, description of ecological networks has been typically limited to one dimension, in part due to methodological challenges in analyzing multi-dimensionality. In this talk, I will present a framework to analyze networks with more than one dimension, namely Ecological Multilayer Networks. I will use this framework to explore two examples of temporal multilayer networks: (1) the structure of a community of host and parasite species; and (2) the population-genetic structure of the human malaria parasite. While these two examples differ in their underlying theory, types of data and questions, they unite to show that incorporating higher dimensions using ecological multilayer networks can profoundly change our understanding of ecological systems.
