Ecological information of ring width, stable carbon isotope composition and wood anatomical variables in tropical tree rings - A contribution to dendrochronology in the tropics
(2012-04-25)Trees are long living organisms and record ecologically relevant information in their growth rings. Studying tree growth on the base of tree rings can help to fill some of the major research gaps concerning the age and ... -
Ecological Management of Tropical forests: Implications for climate change and Carbon Fluxes
(2010-12-20)Tropical deforestation and forest degradation contributes to more than 20% of the global greenhouse gases emitted. Deforestation and its impacts can be more easily estimated with satellite ... -
Econometric Analysis of global wood markets and its implications on in-ternational forest products modelling
(2023-03-03)Global economic systems are changing due to several possible influences, like globalization, climate change, or social transformation. Even though, the wood markets analysis is well established and de-veloped for many kinds ... -
Ecophysiological field studies of phosphorus nutrition of beech (Fagus sylvatica)
(2021-10-19)Phosphorus (P) is an essential element for plant nutrition because it is required for many essential biomolecules such as nucleotides, membrane lipids and ATP. Plants take up P as inorganic phosphate (Pi) from soil solutions. ... -
Ecosystem Approach: Ecological Functions of Forest in Human-Dominated Area
(2014-09-17)Signing and ratification of the Convention on Biological Diversity (UN-CBD) and its adoption into National Law have also affected the Indonesian Forestry sector. The Ministry of Forestry has gradually changed its policy ... -
Effect of land use on soil fertility and carbon sequestration
(2018-03-26)Land-use change, particularly the conversion of natural forest to agriculture to sustain the growing global population, has severe environmental impacts, including emission of greenhouse gases, diminished biodiversity, and ... -
Effects of biotic and abiotic factors on the spatial distribution of enzyme activities in the soil
(2018-11-27)Enzymes produced by plant and microorganisms are crucial to soil functions as they decompose insoluble macromolecules organic compound to smaller, soluble molecules which can be assimilated by cells. The enzymes are spatial ... -
Effects of increased nitrogen input on the net primary production of a tropical lower montane rain foest, Panama
(2009-09-11)Increasing anthropogenic nitrogen (N) deposition from agricultural and industrial use, legume cultivation, combustion of fossil fuels, and biomass burning has until recently been a problem ... -
Effects of insect mass outbreaks on the C and N balance in forest ecosystems
(2019-06-27)Intensive defoliation by phytophagous insects in forests is accompanied by high amounts of organic litter deposition which affects biogeochemical processes in soil, thereby changing nutrient recycling and release as well ... -
Effects of managed forest stand composition on small mammal demography and reciprocal effects on seed predation patterns in Northern Germany
(2024-04-08)In an effort to ameliorate the impacts of climate change, forest managers in Central Europe increasingly turn to conifer species that produce higher yields and are better adapted to projected future climatic conditions. ... -
