Combining ecosystem modelling and remote-sensing to establish the spatial and temporal dynamics of the carbon budget of fast-growing tropical Eucalyptus plantations [PDF]

, 2009
In the aim of estimating regional-scale carbon budgets of Eucalyptus plantations, the G'Day ecosystem model was combined with remotely-sensed estimates of the daily fraction of absorbed photosynthetically active radiation (fAPAR).

Perennial Legumes Pueraria phaseoloides and Leucaena leucocephala Exhibit High Potential for Fertility Restoration of Degraded Mined Soils in Ghana

Journal of Plant Nutrition and Soil Science, EarlyView.
Revegetating the subsoil layer of abandoned gold mined sites with the perennial legumes Leucaena Leucocephala, Pueraria phaseoloides and Gliricidia sepium without any soil amendments increases the content of soil organic carbon and important macro‐nutrients, which are crucial for restoring soil health and productivity. These improvements in soil health

The keys to reduce environmental impacts of palm oil [PDF]

, 2018
Oil palm is largely criticised for its impact on the environment. According to Life Cycle Assessment studies, the agricultural stage proved to be a major contributor to most of the potential environmental impacts, notably global warming, eutrophication ...

The context of REDD+ in the Lao People's Democratic Republic: drivers, agents and institutions [PDF]

, 2013
This report explores the drivers (both direct and indirect) of deforestation and forest degradation and discusses the political, economic and social opportunities and constraints that will influence the design and implementation of REDD+ in Laos.

Holocene sea‐level and environmental changes on the Isle of Mull, Scotland

Journal of Quaternary Science, EarlyView.
ABSTRACT Sea‐level and coastal changes are reconstructed on the Isle of Mull, western Scotland, from 10 988 to 10 507 cal BP to the present. This research has produced the first SLIP for the Isle of Mull. A multiproxy approach including pollen, spore, foraminifera and diatom analyses reveals palaeoenvironmental changes from two coastal sites.

Soil fungi communities from young Scots pine plantations affected with root rot

Acta Mycologica, 2013
The aim of work was to investigate the qualitative and quantitative characteristic features of soil fungi associations occurring in I class pine stands threatened by pathogens of tree roots in Zielonka Experimental Forest District. During the mycological

Effects of land use pattern on invasive plant diversity in Guinean savanna ecosystems of Togodo protected area, Togo [PDF]

, 2018
Tropical natural ecosystems host a very diverse flora and fauna and are key ecosystems for global climate and biogeochemical regulation. Unfortunately, in West African landscapes, large areas of savanna and forest have been progressively replaced or ...

From shape to source: sedimentary charcoal morphology as a proxy for tropical burned biomass composition

Journal of Quaternary Science, EarlyView.
ABSTRACT Sedimentary charcoal elongation is increasingly being used in paleoecology to distinguish herbaceous from woody fuel in past fires. However, the relationship between charcoal morphotypes and plant types has never been formally tested in tropical environments, despite its potential to improve understanding of fire regimes and deforestation, and

Wood density variation in Serbian Spruce: A comparative study of natural stands and plantations

Glasnik Šumarskog Fakulteta Univerziteta u Banjoj Luci
Serbian spruce (Picea omorika Pančić/Purkyně) is a Tertiary relict and an endemic species of the Balkan Peninsula, whose limited distribution range and pronounced ecological specificity make the study of its physical properties particularly important ...

Modelling of selection and mating decisions in tree breeding programs [PDF]

, 1996
Hardwood trees from the temperate forests of southern Australia are an important source of timber for high quality paper. Two species in particular, Eucalyptus globulus and Eucalyptus nitens are well suited to this purpose and are now widely grown in ...
