Stabilization of recent soil carbon in the humid tropics following land use changes: evidence from aggregate fractionation and stable isotope analyses
Keywords: Carbon sequestration - Ecuador - Mean residence time - Pasture - Secondary forest - Soil type - Texture - Water-stable aggregates
Evidence for hybridization and introgression within a species-rich oak (Quercus spp.) community
Background: Analysis of interspecific gene flow is crucial for the understanding of speciation processes and maintenance of species integrity. Oaks (genus Quercus, Fagaceae) are among the model species for the study of ...
Triangulation based inclusion probabilities: a design-unbiased sampling approach
(Springer US, 2011)
A probabilistic sampling approach for design-unbiased estimation of area-related quantitative characteristics of spatially dispersed population units is proposed. The developed field protocol includes a fixed number of 3 ...
Soil Nitrogen-Cycling Responses to Conversion of Lowland Forests to Oil Palm and Rubber Plantations in Sumatra, Indonesia.
Rapid deforestation in Sumatra, Indonesia is presently occurring due to the expansion of palm oil and rubber production, fueled by an increasing global demand. Our study aimed to assess changes in soil-N cycling rates with ...
Global patterns and drivers of phylogenetic structure in island floras.
Islands are ideal for investigating processes that shape species assemblages because they are isolated and have discrete boundaries. Quantifying phylogenetic assemblage structure allows inferences about these processes, ...
Water scarcity and oil palm expansion: social views and environmental processes
Conversions of natural ecosystems, e.g., from rain forests to managed plantations, result in significant changes in the hydrological cycle including periodic water scarcity. In Indonesia, large areas of forest were lost ...
Towards a different attitude to uncertainty
The ecological literature deals with uncertainty primarily from the perspective of how to reduce it to acceptable levels. However, the current rapid and ubiquitous environmental changes, as well as anticipated rates of ...
Ectomycorrhizal Colonization and Diversity in Relation to Tree Biomass and Nutrition in a Plantation of Transgenic Poplars with Modified Lignin Biosynthesis
Wood from biomass plantations with fast growing tree species such as poplars can be used as an alternative feedstock for production of biofuels. To facilitate utilization of lignocellulose for saccharification, transgenic ...
Spatial Characteristics of Tree Diameter Distributions in a Temperate Old-Growth Forest
This contribution identifies spatial characteristics of tree diameter in a temperate forest in north-eastern China, based on a fully censused observational study area covering 5006600 m. Mark correlation analysis with ...
International and Domestic Sustainable Forest Management Policies: Distributive Effects on Power among State Agencies in Bangladesh
The last two decades of forest policy discussions have been dominated by calls for sustainable management of forest resources. Consequently, multiple international and domestic policies, supporting sustainable forest ...
