Ecosystems Center researchers' model of nutrient flows in an estuarine ecosystem

Caption reads: "Figure 4: A diagrammatic model of carbon and nitrogen flow in an estuarine ecosysem that emphasizes inputs of organic carbon and nitrogen and inorganic nutrients from upland watersheds and processing by the estuarine food web. Compartments of the mathematical model are shown in the box. The inorganic nutrients compartment comprises both ammonium and nitrate. The organic matter compartment comprises three distinct components: labile nitrogenous material, labile carbohydrate material and refractory nitrogenous materal."

Created: 1985Map of Ecosystems Center researchers' forest watershed fertilizer study in Maine

Caption reads: "Figure 1: The dashed lines mark two catchments (watersheds) at the Bear Brooks Watersheds site in Maine. Both catchments are located on a southeast-facing slope and drained by streams that persist throughout the year (dark lines). The shaded catchment was treated with fertilized labeled with 15N during 1991; the other served as a control. Filled trianges show sampling locations in the fertilized area."
Created: 1992Simulation of global annual net primary production from Ecosystems Center researchers' Terrestrial Ecosystem Model

Caption reads: "Figure 2. Annual net primary production (NPP) for undisturbed mature vegetation of the earth's ecosystems as determined by the Terrestrial Ecosystem Model (TEM) for current climate at atmosphereic carbon dioxide levels."
