Technological improvement of Portuguese Pine wood by modification
(2013-09-04)Wood has a long tradition as a structural and building material in Portugal. In the last decade, the European trend to improve physical properties of wood by chemical modification allowed extending its performance on ... -
Technological Investigation of Prosopis leavigata Wood from Northeast Mexico
(2007-10-10)This study describes the anatomical properties of Prosopis laevigata trees found in northeast Mexico. The chemical composition and the topochemical distribution of lignin and phenolic ... -
The Distribution of the Genetic Diversity in <i>Araucaria angustifolia</i> (Bert.) O. Kuntze populations and its implications for the conservation of the species
(2007-10-02)Genetic markers have been widely used for the assessment of levels of genetic diversity in various species, for the determination of their conservation status and for the derivation of ... -
The effect of neighborhood identity on seasonal tree growth responses and ecophysiological characteristics of European beech (Fagus sylvatica L.)
(2020-01-17)Climate change related rise in mean surface (air) temperature, altered intra-annual thermal and precipitation regimes as well as an expected increase of extreme weather events which are also prognosticated for large parts ... -
The effect of reduced management intensity on soil nutrient dynamics in a large-scale oil palm plantation: soil nitrogen cycle, asymbiotic nitrogen fixation and nutrient leaching losses
(2020-08-04)Oil palm plantations are rapidly expanding in the tropics, triggered by increasing demand of vegetable oil and by their high productivity. Large part of palm oil is produced in large-scale plantations employing intensive ... -
The Effect of Root Volatiles on the Orientation Behaviour of Cockchafer Larvae in the Soil
(2011-06-24)The present study investigates the effect of root volatiles on the orientation behaviour of cockchafer larvae Melolontha hippocastani in the soil. Cockchafer larvae are known as severe pests ... -
The environmental impact of selective logging in southern Cameroon: soil disturbance, nutrient budget and greenhouse gas fluxes
(2020-02-26)Tropical forests play an important role in climate change mitigation through carbon sequestration in the vegetation and soils, which can be released to the atmosphere through deforestation and forest degradation. One of ... -
The forest policies of international regimes in different world regions: issue specificity, formalisation, and hegemony as drivers
(2021-06-15)Forests are multifunctional, including economic, social, and environmental purposes. These governed by a combination of sub-national and national and global and regional regimes. Political analysis is mainly focused on ... -
The impact of canopy composition on the nutritional statusof an admixed spruce and beech forest at Solling,central Germany
(2008-04-11)It was hypothesised that in mixed spruce-beech forest ecosystems the heterogeneity in canopy composition may create different micro-sites (units) in the forest floor and the mineral soil with different ecological cha ... -
The influence of melamine treatment in combination with thermal modification on the properties and performance of native hardwoods
(2020-04-30)The objective of this study was to improve the properties of native hardwoods and find potential new applications in exposed environments that had previously been unsuitable for most of these species. Certain properties ... -
The isotopic composition of CO2 and H2Ov fluxes in a managed beech forest - Instrument tests and ecological application of two laser-based absorption spectrometers
(2018-10-10)Stable isotopes provide valuable insights into the coupled carbon dioxide (CO2) and water vapor (H2Ov) cycle on scales ranging from one leaf to global. In particular for applications under field conditions, recent progress ... -
The use of remote sensing data to monitor land use systems and forest variables of the tropical rainforest landscape under transformation in Jambi Province, Sumatra, Indonesia
(2018-01-17)The transformation of land use in the tropics has received major attention in the last decades due to the rapid loss of tropical forests. In particular, large forest areas have been deforested and turned into agricultural ... -
Threatened tree species across conservation zones in a nature reserve of North-Western Vietnam
(2017-03-21)The high diversity of tree species in tropical forests is driven by a large proportion of rare species. Rare species are vulnerable and threatened to extirpation and extinction when their habitats are destroyed. This study ... -
Tibetan pasture degradation under the impact of global change: Consequences for carbon and nutrient cycles and recovery strategies
(2017-07-27)The Tibetan Plateau hosts the world’s largest alpine pastoral ecosystems, dominated by the endemic sedge Kobresia pygmaea C.B.Clarke. Overgrazing on the Tibetan Plateau has caused severe degradation of vegetation and soils ... -
Trace gas fluxes and belowground carbon allocation in tropical montane forest soils of Southern Ecuador
(2011-10-12)Tropical forest soils are important sources of the greenhouse gases carbon dioxide (CO2) and nitrous oxide (N2O), and of nitric oxide (NO), a precursor of ozone production. They are also ... -
Trace gas fluxes from soils and tree stems of rainforests and cacao agroforests in the Congo Basin, Cameroon
(2020-06-11)Tropical rainforests play a crucial role in biogeochemical cycles and global climate dynamics. Yet, research efforts to quantify the main sources and sinks of trace greenhouse gases lags behind that of other biomes. The ... -
Trace Gas Fluxes from Tropical Montane Forests of Southern Ecuador
(2011-11-30)Methane (CH4), nitrous oxide (N2O) and carbon dioxide (CO2) are major greenhouse gases but their fluxes in tropical montane forests are hardly known. The distribution of known sources of ... -
Tracing shifting cultivation in the Nam Ton watershed (Lao PDR) by multispectral image-to-image change detection techniques with statistical verification
(2020-10-02)When looking for critical areas in the context of erosion and degradation in Laos, the regions that are affected by shifting cultivation are prior and most distinct visual. Up to now the distribution and extent of these ... -
Transpiration by oil palm and rubber plantations: refining methods and delineating differences
(2016-10-18)Oil palm (Elaeis guineensis Jacq.) and rubber (Hevea brasiliensis Müll. Arg.) plantations cover large areas in tropical regions and may still expand further. In contrast, the area covered by natural forests has strongly ...
