FEASIBILITY STUDY OF USING VIRTUAL REALITY FOR INTERACTIVE AND IMMERSIVE SEMANTIC SEGMENTATION OF SINGLE TREE STEMS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2022
Forest digitisation is one of the next major challenges to be tackled in the forestry domain. As a consequence of tremendous advances in 3D scanning technologies, broad areas of forest can be mapped in 3D dramatically faster than 20 years ago ...

Ammonia emissions from deciduous forest after leaf fall [PDF]

open access: yes, 2013
The understanding of biochemical feedback mechanisms in the climate system is lacking knowledge in relation to bi-directional ammonia (NH3) exchange between natural ecosystems and the atmosphere.

Nitrogen cycling, forest canopy reflectance, and emergent properties of ecosystems [PDF]

open access: yes, 2013
In Ollinger et al. (1), we reported that mass-based concentrations of nitrogen in forest canopies (%N) are positively associated with whole-canopy photosynthetic capacity and canopy shortwave albedo in temperate and boreal forests, the latter result ...

RNAi Suppression of LEAFY Gives Stable Floral Sterility, and Reduced Growth Rate and Leaf Size, in Field-Grown Poplars

open access: yesPlants, 2021
The central floral development gene LEAFY (LFY), whose mutation leads to striking changes in flowering and often sterility, is commonly expressed in non-floral structures; however, its role in vegetative development is poorly understood.

A multi‐data ensemble approach for predicting woodland type distribution: Oak woodland in Britain

open access: yesEcology and Evolution, 2021
Interactions between soil, topography, and climatic site factors can exacerbate and/or alleviate the vulnerability of oak woodland to climate change. Reducing climate‐related impacts on oak woodland habitats and ecosystems through adaptation management ...

Diversity patterns of ground beetles and understorey vegetation in mature, secondary and plantation forest regions of temperate Northern China [PDF]

open access: yes, 2015
Plantation and secondary forests form increasingly important components of the global forest cover, but our current knowledge about their potential contribution to biodiversity conservation is limited.

Impacts of air pollution on human and ecosystem health, and implications for the National Emission Ceilings Directive. Insights from Italy [PDF]

open access: yes, 2019
Across the 28 EU member states there were nearly half a million premature deaths in 2015 as a result of exposure to PM2.5, O3 and NO2. To set the target for air quality levels and avoid negative impacts for human and ecosystems health, the National ...

Temperature response of soil carbon decomposition depends strongly on forest management practice and soil layer on the eastern Tibetan Plateau

open access: yesScientific Reports, 2017
How forest management practice impacts the temperature response of soil carbon decomposition remains unclear in Tibetan boreal forests. Here, an experiment was conducted to compare soil carbon decomposition of two layers (organic and mineral) in three ...

Scientifically based biodiversity management in timber concessions: contribution to conservation and sustainable use of biodiversity [PDF]

open access: yes, 2016
During the past 25 years, forest laws in Central African countries have undergone major changes. Management plans were made mandatory: nearly 19 million hectares of timber concessions (38% of total granted concessions) were subject to a management plan ...
