NCNA: Integrated platform for constructing, visualizing, analyzing and sharing human-mediated nitrogen biogeochemical networks

Human alterations to the nitrogen (N) cycle are closely associated with global environmental and climate change. New tools are necessary to model and analyze the highly complex N cycles emerging from human-mediated ecosystems. We developed a new software. NCNA, to provide three functions: a) rigorous reconstruction of quasi-empirical models (QEMs), b) computer-aided interface for data collection and automatic sensitivity analysis, and c) automatic generation, visualization and network environ analysis (NEA) of N cycling networks.
