Effects of the interception of litterfall by the understory on carbon cycling in eucalyptus plantations of South China.

open access: yesPLoS ONE, 2014
For the purposes of forest restoration, carbon (C) fixation, and economic improvement, eucalyptus (Eucalyptus urophylla) has been widely planted in South China.

Light use efficiency in pure and mixed Eucalyptus and Acacia mangium plantations with different stocking densities [PDF]

open access: yes, 2019
Competition for light in mixed-species plantations is a main limiting factor for tree growth. Understanding the light absorption and light use efficiency for each species at different planting densities and spatial arrangement of trees is essential for ...

Differences in the Amount of Litterfall and Mercury Concentration in Litterfall Leaves of Typical Forest Ecosystems in China

open access: yesForests
Mercury, a global pollutant with both persistence and high toxicity, has remained a focal point in environmental science research over the past half-century. As a key pathway in the terrestrial mercury cycle, plants actively assimilate gaseous elemental mercury (Hg0) through leaf stomata, constituting a critical pathway for terrestrial mercury cycling.

Litterfall production and fine root dynamics in cool-temperate forests

open access: yesPLOS ONE, 2017
Current understanding of litterfall and fine root dynamics in temperate forests is limited, even though these are the major contributors to carbon and nutrient cycling in the ecosystems. In this study, we investigated litterfall and fine root biomass and production in five deciduous and four coniferous forests at the Gwangneung Experimental Forest in ...

Litterfall production, decomposition and nutrient accumulation in Sundarbans mangrove forests, Bangladesh

open access: yesForest Science and Technology, 2019
Litterfall production and litter decomposition are the principal factors for controlling the functions of mangroves to store and cycle carbon and nutrients within the ecosystem. We analyzed the litterfall production, its seasonality, patterns and changes

Productivity and carbon allocation in monospecific and mixed-species plantations of Eucalyptus grandis and Acacia mangium in Brazil [PDF]

open access: yes, 2010
Nitrogen fertilizer inputs are required in fast growing eucalypt plantations to meet tree requirements, and to compensate for the large nitrogen outputs associated with wood exportation at the end of the short rotations. Due to the economic and potential

DIRECT ESTIMATION OF ABOVEGROUND FOREST PRODUCTIVITY THROUGH HYPERSPECTRAL REMOTE SENSING OF CANOPY NITROGEN [PDF]

open access: yes, 2002
The concentration of nitrogen in foliage has been related to rates of net photosynthesis across a wide range of plant species and functional groups and thus represents a simple and biologically meaningful link between terrestrial cycles of carbon and ...

Seasonal LAI in slash pine estimated with LANDSAT TM [PDF]

open access: yes
The leaf area index (LAI, total area of leaves per unit area of ground) of most forest canopies varies throughout the year, yet for logistical reasons it is difficult to estimate anything more detailed than a seasonal maximum LAI.

Boom and Bust Carbon-Nitrogen Dynamics during Reforestation [PDF]

open access: yes, 2017
Legacies of historical land use strongly shape contemporary ecosystem dynamics. In old-field secondary forests, tree growth embodies a legacy of soil changes affected by previous cultivation.

Response of short rotation forestry to dairy farm-pond effluent irrigation : a thesis presented in partial fulfilment of the requirements for the degree of Master of Philosophy in Agricultural Engineering at Massey University [PDF]

open access: yes, 1999
A growing concern to protect the environment has prompted Regional Councils in New Zealand to monitor compliance under the Resource Management Act (1991) covering the discharge of wastewater into waterways.
