Decadal trends in net ecosystem production and net ecosystem carbon balance for a regional socioecological system

Forest Ecology and Management, 2011
Carbon sequestration is increasingly recognized as an ecosystem service, and forest management has a large potential to alter regional carbon fluxes notably by way of harvest removals and related impacts on net ecosystem production (NEP). In the Pacific Northwest region of the US, the implementation of the Northwest Forest Plan (NWFP) in 1993 ...

Net ecosystem production in clear‐water and brown‐water lakes

Global Biogeochemical Cycles, 2012
We 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.

Is Net Ecosystem Production Equal to Ecosystem Carbon Accumulation?

Ecosystems, 2006
Net ecosystem production (NEP), defined as the difference between gross primary production and total ecosystem respiration, represents the total amount of organic carbon in an ecosystem available for storage, export as organic carbon, or nonbiological oxidation to carbon dioxide through fire or ultraviolet oxidation.

Net primary production and net ecosystem production of a boreal black spruce wildfire chronosequence

Global Change Biology, 2004
AbstractNet primary production (NPP) was measured in seven black spruce (Picea mariana(Mill.) BSP)‐dominated sites comprising a boreal forest chronosequence near Thompson, Man., Canada. The sites burned between 1998 and 1850, and each contained separate well‐ and poorly drained stands.

Net Ecosystem Production of Boreal Larch Ecosystems on the Yenisei Transect

Mitigation and Adaptation Strategies for Global Change, 2006
The study was carried out in the Turukhansk Research Station of Yenisei Transect (65°46′N, 89°25′E). Larch (Larix gmelinii (Rupr.) Rupr.) is the dominant overstory tree species. The research has been conducted on four permanent test plots in same-age mature (110-year old) and overmature (380-year old) post-fire larch stands of green moss and lichen ...

Impact of precipitation dynamics on net ecosystem productivity

Global Change Biology, 2012
AbstractNet ecosystem productivity (NEP) was measured on shortgrass steppe (SGS) vegetation at the USDA Central Plains Experimental Range in northeastern Colorado from 2001 to 2003. Large year‐to‐year differences were observed in annual NEP, with >95% of the net carbon uptake occurring during May and June.

Seasonal shift in factors controlling net ecosystem production in a high Arctic terrestrial ecosystem

Journal of Plant Research, 2009
We examined factors controlling temporal changes in net ecosystem production (NEP) in a high Arctic polar semi-desert ecosystem in the snow-free season. We examined the relationships between NEP and biotic and abiotic factors in a dominant plant community (Salix polaris-moss) in the Norwegian high Arctic.

Nutrient Limitation Of Net Primary Production In Marine Ecosystems

Annual Review of Ecology and Systematics, 1988
The question of nutrient limitation of primary production in estuaries and other marine ecosystems has engendered a great deal of debate. Although nitrogen is often named as the primary limiting nutrient in seawater (3, 17-19, 50, 52, 55, 61, 76, 80), this is by no means universally accepted. Many workers have argued that phosphorus is limiting (58, 71)
