Nutrient response efficiency, soil greenhouse gas fluxes, and nutrient leaching losses from a large-scale oil palm plantation under conventional and reduced management practices
(2023-07-06)The area of oil palm plantations has expanded rapidly in the tropics over the past few decades due to the high demand for palm oil and the considerable economic benefits. Oil palm is playing a vital role in the global ... -
Picea abies and climate change – does increasing thinning intensity prevent drought stress?
(2017-10-11)The predicted increase in frequency of intense and prolonged drought events challenges forest management. Centuries of forest management has led to Norway spruce (Picea abies [L.] Karst.) monocultures outside its natural ... -
Power-Linked Evaluation of State Forest Organizations
(2021-06-24)Globally, state forest organizations have a wide scope of tasks. They play a central role in managing state-owned forestlands. In addition, they are responsible for implementing forest law on both private and state-owned ... -
Predicting evapotranspiration from drone-recorded land surface temperatures - Method testing and development
(2020-09-08)Evapotranspiration (ET) is a central flux in the hydrological cycle on a regional and on a global scale. Transpiration from plants is the largest water flux from terrestrial surfaces, accounting for the major part of ... -
Quantifying the impact of forest management intensity and tree species diversity on individual tree shape and three-dimensional stand structure
(2020-11-04)The three-dimensional distribution of trees and their crowns is an essential characteristic of forest ecosystems that is directly related to several ecosystem functions and services. Silvicultural interventions modify the ... -
Quantifying three-dimensional stand structure and its relationship with forest management and microclimate in temperate forest ecosystems
(2018-02-01)Summary Forest management modifies the spatial structure of forest ecosystems, which is considered to be relevant for habitat availability and biodiversity as well as several ecosystem processes and functions. Contrary ... -
Rainfall partitioning and soil water dynamics along a tree species diversity gradient in a deciduous old-growth forest in Central Germany
(2010-09-06)Species diversity effects have been extensively investigated in grassland ecosystems, however, little is known about the influence of tree species diversity on the forest water cycle. ... -
Rainfall partitioning in differently used montane rainforests of Central Sulawesi, Indonesia
(2007-01-31)This study was conducted within the project 'Stability of Rainforest Margins in Indonesia' (STORMA) along the margins of the Lore Lindu National Park in Central Sulawesi, Indonesia. The ... -
Raumzeitliche Dynamik der Parameter des Energie-, Wasser und Spurengashaushalts nach Kleinkahlschlag
(2010-05-18)The conversion of coniferous monocultures into deciduous and mixed forest is a priority aim of silvicultural efforts in Germany. The goal is to create robust forests which are resilient ... -
Responses of net primary production and plant-available soil nutrients to elevated nutrient input in a tropical forest on highly weathered soil
(2022-06-07)Globally, tropical forests are highly productive ecosystems and play a critical role in sequestering anthropogenic carbon dioxide (CO2) from the atmosphere, accounting for up to half of the terrestrial biosphere’s carbon ... -
Smallholder vanilla agroforestry in Madagascar: biodiversity, ecosystem services and yields in a land-use context
(2021-03-18)Land-use change threatens biodiversity and ecosystem services worldwide. Tropical areas are currently particularly affected: natural ecosystems are being transformed into large-scale monocultures or small-scale mosaic ... -
Soil Carbon Dioxide dynamics and Nitrogen cycling in an Eastern Amazonian Rainforest, Caxiuana, Brazil
(2006-07-13)The significance of climate changes and of increasing N deposition to the interaction of both carbon and nitrogen cycles in tropical soils is still unknown and deserves more attention. In ... -
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 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 ... -
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 ... -
Tree and oil palm water use: scaling, spatial heterogeneity and temporal dynamics (Sumatra, Indonesia)
(2020-10-30)Transpiration is a central flux in the terrestrial water cycle and is considered an important ecosystem service for atmosphere and hydrosphere regulation. Transpiration is strongly affected by land cover and land-use ... -
Tree water uptake partitioning and water use rates in a temperate mixed forest
(2014-01-09)Little information is available on the relationship between tree species diversity and forest stand water use although water availability is considered a major control of productivity in forests of central Europe and other ... -
Tree Water Use Strategies in a Neotropical Dry Forest
(2019-10-11)Trees in tropical dry forests (TDFs) developed different drought coping strategies including e.g. succulence of different plant organs, wood anatomical traits and leaf phenology. Apart from the fact that water availability ... -
