Aboveground biomass and carbon in a South African mistbelt forest and the relationships with tree species diversity and forest structures
(MDPI, 2016)ENGLISH ABSTRACT: Biomass and carbon stocks are key information criteria to understand the role of forests in regulating global climate. However, for a bio-rich continent like Africa, ground-based measurements for accurate ... -
Analysing taxonomic structures and local ecological processes in temperate forests in North Eastern China
(BioMed Central, 2017)Background: One of the core issues of forest community ecology is the exploration of how ecological processes affect community structure. The relative importance of different processes is still under debate. This study ... -
Assessing biological dissimilarities between five forest communities
(SpringerOpen (part of Springer Nature), 2019-06-06)Background: Dissimilarity in community composition is one of the most fundamental and conspicuous features by which different forest ecosystems may be distinguished. Traditional estimates of community dissimilarity are ... -
Atomic force microscopy to determine the surface roughness and surface polarity of cell types of hardwoods commonly used for pulping
(Academy of Science for South Africa, 2007)ATOMIC FORCE MICROSCOPY CAN BE USED to determine the surface roughness and surface polarity of different cell types originating from hardwood species. This analytical method allows images representing the topography and ... -
Characteristics of selected non-woody invasive alien plants in South Africa and an evaluation of their potential for electricity generation
(University of Cape Town, Energy Research Centre, 2017)ENGLISH ABSTRACT: Alien invasive plants (AIPs) pose a threat to the existence of plant and animal biodiversity in the ecosystems they invade. They need to be cleared, monitored and eventually eradicated from the landscape. ... -
Climate as possible reproductive barrier in Pinus radiata (D. Don) interspecific hybridisation
(Marin Dracea National Research-Development Institute in Forestry, 2017)Historically, interspecific hybridisation with Pinus radiata D. Don had limited success. The effect of environmental conditions and position of pollination bags in the tree were investigated as possible hybridisation ... -
Climate change effects in the Western Himalayan ecosystems of India : evidence and strategies
(SpringerOpen, 2017)Background: The fragile landscapes of the Himalayan region are highly susceptible to natural hazards, and there is ongoing concern about current and potential climate change impacts. This study provides background information ... -
Comparing Johnson’s SBB, Weibull and Logit-Logistic bivariate distributions for modeling tree diameters and heights using copulas
(Instituto Nacional de Investigacion y Tecnología Agraria y Alimentaria, 2016-04)Aim of study: In this study we compare the accuracy of three bivariate distributions: Johnson’s SBB, Weibull-2P and LL-2P functions for characterizing the joint distribution of tree diameters and heights. Area of study: ... -
A comparison of two methods of data collection for modelling productivity of harvesters : manual time study and follow-up study using on-board-computer stem records
(Marin Dracea National Research-Development Institute in Forestry, 2018)Abstract. Productivity of a mechanized P. patula cut-to-length harvesting operation was estimated and modelled using two methods of data collection: manual time study and follow-up study using StanForD stem files. The ... -
Drivers of seedling survival in a temperate forest and their relative importance at three stages of succession
(John Wiley & Sons Ltd., 2015-09-10)Negative density dependence (NDD) and niche partitioning have been perceived as important mechanisms for the maintenance of species diversity. However, little is known about their relative contributions to seedling survival. ... -
Effect of ascorbic acid and yeast strain on sauvignon blanc wine quality
(South African Society for Enology and Viticulture, 2001)Sauvignon blanc cultivar-typical aroma is affected by different components of which 2-methoxy-3-isobutylpyrazine and 4-mercapto-4-methylpentan-2-one are probably the most important. Climatic, viticultural and oenological ... -
Effects of density dependence in a temperate forest in northeastern China
(Springer Nature, 2016-09-08)ENGLISH ABSTRACT: Negative density dependence may cause reduced clustering among individuals of the same species, and evidence is accumulating that conspecific density-dependent self-thinning is an important mechanism ... -
Essential environmental variables to include in a stratified sampling design for a national-level invasive alien tree survey
(Italian Society of Silviculture and Forest Ecology, 2020)ENGLISH ABSTRACT: There is a direct relationship between the abundance of biological invasions and their impact, which means that it is important to capture spatial patterns in their abundance and use this information to ... -
Evaluation of Irvingia kernels extract as biobased wood adhesive
(SpringerOpen, 2020-02-22)Irvingia tree species have been earmarked for domestication in many countries due to their potential as raw materials for various applications, which include biodiesel, cosmetics, perfume, soap, etc. Presently, there is ... -
Facilitating the recovery of natural evergreen forests in South Africa via invader plant stands
(SpringerOpen, 2017)ENGLISH ABSTRACT: Contrary to general belief, planted and naturalized stands of introduced species facilitate the recovery of natural evergreen forests and their diversity. Forest rehabilitation actions are often performed ... -
Functional and phylogenetic diversity determine woody productivity in a temperate forest
(Wiley Open Access, 2018)ENGLISH ABSTRACT: Understanding the relationships between biodiversity and ecosystem productivity has become a central issue in ecology and conservation biology studies, particularly when these relationships are connected ... -
Growth at the microscale : long term thinning effects on patterns and timing of intra-annual stem increment in radiata pine
(SpringerOpen, 2018-10-09)Background: Stem radial growth in forests is not uniform. Rather, it is characterized by periods of relatively fast or slow growth, or sometimes no growth at all. These fluctuations are generally a function of varying ... -
How beta diversity and the underlying causes vary with sampling scales in the Changbai mountain forests
(John Wiley & Sons Ltd, 2017-10)ENGLISH ABSTRACT: This study aims to establish a relationship between the sampling scale and tree species beta diversity temperate forests and to identify the underlying causes of beta diversity at different sampling ... -
Impact of climate trends and drought events on the growth of oaks (Quercus robur L. and Quercus petraea (Matt.) Liebl.) within and beyond their natural range
(MDPI, 2018-02-28)ENGLISH ABSTRACT: Due to predicted climate change, it is important to know to what extent trees and forests will be impacted by chronic and episodic drought stress. As oaks play an important role in European forestry, this ... -
Influence of drone altitude, image overlap, and optical sensor resolution on multi-view reconstruction of forest images
(MDPI, 2019)Recent technical advances in drones make them increasingly relevant and important toolsfor forest measurements. However, information on how to optimally set flight parameters and choosesensor resolution is lagging behind ...
