Impact of icebergs on net primary productivity in the Southern Ocean [PDF]

open access: yesThe Cryosphere, 2017
Productivity in the Southern Ocean (SO) is iron-limited, and supply of iron dissolved from aeolian dust is believed to be the main source from outside the marine environment. However, recent studies show that icebergs could provide a comparable amount of

Human Appropriated Net Primary Productivity of Complex Mosaic Landscapes [PDF]

open access: yesFrontiers in Forests and Global Change, 2019
Quantifying human impact on the environment is increasingly important and particularly so in complex mosaic landscapes. Such landscapes are prolific in the developing world, notably in West African, small holder cocoa farming communities.

Degradation of net primary production in a semi-arid rangeland [PDF]

open access: yesBiogeosciences, 2016
Abstract. Anthropogenic land degradation affects many biogeophysical processes including reductions of net primary production (NPP). Degradation occurs at scales from small fields to continental and global. While measurement and monitoring of NPP in small areas is routine in some studies, for scales larger than 1 km2, and certainly global, there is no ...

Ozone and haze pollution weakens net primary productivity in China [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
Atmospheric pollutants have both beneficial and detrimental effects on carbon uptake by land ecosystems. Surface ozone (O3) damages leaf photosynthesis by oxidizing plant cells, while aerosols promote carbon uptake by increasing diffuse radiation and ...

Net primary production of forests: a constant fraction of gross primary production? [PDF]

open access: yesTree Physiology, 1998
Considerable progress has been made in our ability to model and measure annual gross primary production (GPP) by terrestrial vegetation. But challenges remain in estimating maintenance respiration (R(m)) and net primary production (NPP). To search for possible common relationships, we assembled annual carbon budgets from six evergreen and one deciduous

NPP and Vegetation Carbon Sink Capacity Estimation of Urban Green Space Using the Optimized CASA Model: A Case Study of Five Chinese Cities

open access: yesAtmosphere, 2023
Urban area is a major source of CO2 and other greenhouse gases. Urban green space (UGS) is an essential element to increase carbon sequestration directly and reduce emission indirectly.
