Net ecosystem production in clear‐water and brown‐water lakes
Global Biogeochemical Cycles, 2012We studied 15 lakes in northern Sweden with respect to primary production and respiration in benthic and pelagic habitats. The lakes were characterized by different concentrations of colored dissolved organic carbon (DOC) of terrestrial origin, forming a gradient ranging from clear‐water to brown‐water lakes.

Seasonal shift in net ecosystem production in a tropical estuary
Limnology and Oceanography, 2003Net ecosystem production was examined in the Mandovi and Zuari estuaries (southwestern India) and the adjoining coastal waters for a period of 1 yr (January to December 1998). The study period encompassed premonsoon, monsoon, and postmonsoon seasons. At the estuarine stations, net ecosystem production showed monthly variation and a transition from net ...

Net primary production of the grass and swamp ecosystems
Contemporary Problems of Ecology, 2008Paper presents estimates of above-ground, below-ground, and total production in grasslands, meadows and steppe of the forest-steppe and steppe regions, and production of moss peat ecosystems of the northern, middle, and southern taiga forests. Total production varies in grasslands from 520 to 6670 g/(m2 year) and depends on hydrothermal conditions and ...

Valuing ecosystem services: A shadow price for net primary production
Ecological Economics, 2007Abstract We analyze the contribution of ecosystem services to GDP and use this contribution to calculate an empirical price for ecosystem services. Net primary production is used as a proxy for ecosystem services and, along with capital and labor, is used to estimate a Cobb Douglas production function from an international panel.

Phosphorus limitation of net production in a confined aquatic ecosystem
Nature, 1984The sediment composition of confined aquatic ecosystems with little terrigenous input reflects net ecosystem production. Here we present nutrient budgets for one such system, Shark Bay in Western Australia, which suggest that net ecosystem production is limited by the oceanographic delivery of P, while the system meets its N requirements by nitrogen ...

Petri Net-Based Affective-Cognitive Modeling for Product Ecosystem Design
Volume 9: 23rd International Conference on Design Theory and Methodology; 16th Design for Manufacturing and the Life Cycle Conference, 2011Product ecosystem design that emphasizes user experience (UX) with both users’ affective and cognitive aspects lends itself to be of primary importance to value-added user satisfaction. In a product ecosystem, there are human users, multiple products, and the ambience. Thus it involves complex human-product-ambience interactions, which contribute to UX
