General Ecosystem Model GEM GEM has been designed to simulate a variety of ecosystem types using a fixed model structure. GEM Structure: 1. The primary ecosystem process feedbacks among the biotic and abiotic sectors of the GEM. 2. Diagram of the model structure, excluding hydrology 3. The hydrologic module of the GEM Across Trophic Level System Simulation ATLSS, GEM and TEM Ecology Model Abstracts Florida International University, Ecohydrology CWR5140, Professor: Dr. F. Miralles, Student: Luis Perez, PID#: 3187490, November, 2009 R. Costanza, C. Fitz, T. Maxwell, F. Sklar, Maryland International Institute for Ecological Economics , June 1993 The Terrestrial Ecosystem Model (TEM) The Terrestrial Ecosystem Model (TEM) is a process-based ecosystem model that describes carbon and nitrogen dynamics of plants and soils for terrestrial ecosystems of the globe. The TEM uses spatially referenced information on climate, elevation, soils, vegetation and water availability as well as soil (and vegetation) specific parameters to make monthly estimates of important carbon and nitrogen fluxes and pool sizes of terrestrial ecosystems. Version Type of Analysis Major Modifications Applications 1.0 Equilibrium Original Examined spatial patterns of long-term mean net primary production (NPP) in South America 2.0 Equilibrium New feedback algorithm between C and N uptake by vegetation Examined spatial patterns of long-term mean NPP across North America
