What is a network? A network is a mathematical description of relationships often visually represented by "nodes" (points representing a subject of interest, e.g., species) and "links" (lines connecting nodes representing interactions). Network conceptualizations have a broad range of utility and can offer a language for articulating the characteristics and properties of complex systems across a variety of fields. Additionally, the use of network diagrams can increase tractability of complex scenarios; as well as bolster understanding of emergent properties of a system that could not be grasped by simply examining its parts. Network metrics can enable one to quantitatively measure the structure of a given area of interest, for instance, an ecological community—providing insights into key areas of interest, such as: stability, robustness, resilience, and persistence. This PowerPoint uses the metric of centrality to illustrate this concept.

DirectorDr. Margaret A. Palmer is Director of SESYNC and a Distinguished University Professor at the University of Maryland, College Park. With a background in hydrology and ecology, Margaret contributes to testing and extending fundamental theory and empirical findings on aquatic ecosystem dynamics. She has worked extensively on the relationship between biodiversity and ecosystem processes, the biogeochemistry of streams and wetlands, and organism dispersal in aquatic ecosystems. She is an international expert on the restoration of streams and rivers and co-author of the book Foundations of Restoration Ecology. Margaret is also known for her work at the interface of water science and policy, having served as a technical advisor and innovator to help build solution-focused teams that solve problems with social, legal, policy and scientific aspects. She is extensively published (Google Scholar), has numerous awards, and remains actively engaged in science matters associated with national and local water policies and actions—particularly those associated with the Appalachians.
