Forests play an important role in regional and global carbon (C) cycles. With extensive afforestation reforestation efforts over the last several decades, forests East Asia have largely expanded, but dynamics of their C stocks not been fully assessed. We estimated biomass all five Asian countries (China, Japan, North Korea, South Mongolia) between 1970s 2000s, using expansion factor method forest inventory data. Forest area density whole region increased from 179.78 × 106 ha 38.6 Mg ha−1 to...
Summary Sun and shade environments place markedly different constraints on the photosynthetic performance of plants. Leaf‐level responses to sun have been extensively investigated, whereas there has much less research functional role crown architecture in these environments. This paper focuses maximizing light capture photosynthesis shaded understories minimizing exposure excess radiation open high Understanding contrasting roles is facilitated by application a three‐dimensional...
This REgional Carbon Cycle Assessment and Processes regional study provides a synthesis of the carbon balance terrestrial ecosystems in East Asia, region comprised China, Japan, North South Korea, Mongolia. We estimate current Asia its driving mechanisms during 1990â2009 using three different approaches: inventories combined with satellite greenness measurements, ecosystem cycle models atmospheric inversion models. The magnitudes Asia's sink from these approaches are comparable:...
AimsUnderstanding of the ecophysiological dynamics forest canopy photosynthesis and its spatial temporal scaling is crucial for revealing ecological response to climate change. Combined observations analyses plant ecophysiology optical remote sensing would enable us achieve these studies. In order examine utility spectral vegetation indices (VIs) assessing ecosystem-level photosynthesis, we investigated relationships between canopy-scale photosynthetic productivity reflectance over seasons 5...
ABSTRACT Diurnal changes in photosynthetic gas exchange and chlorophyll fluorescence were measured under full sunlight to reveal diffusional non‐diffusional limitations diurnal assimilation leaves of Arisaema heterophyllum Blume plants grown either a riparian forest understorey (shade leaves) or an adjacent deforested open site (sun leaves). Midday depressions rate ( A ) leaf conductance water vapour remarkably deeper shade than sun leaves. To evaluate the (i.e. stomatal internal) limitation...
Abstract Background: Recent studies have described a technique that incorporates digital camera to observe aspects of tree phenology, such as leaf expansion and fall. This has shown seasonal patterns red, green blue numbers (RGB_DN) extracted from images differ between species. Aims: To identify the different characteristics phenology species by examining RGB_DN, relationship RGB_DN ecological for various were evaluated throughout year. Methods: The normalised values in situ area index (LAI)...
Abstract Accurate information on the optical properties (reflectance and transmittance spectra) of single leaves is important for an ecophysiological understanding light use by leaves, radiative transfer models remote sensing terrestrial ecosystems. In general, leaf are measured with integrating sphere a spectroradiometer. However, this method usually difficult to grass conifer needles because they too narrow cover sample port typical sphere. Although ways measure have been suggested,...
Aim Although treatment guidelines for pharmacological therapy schizophrenia and major depressive disorder have been issued by the Japanese Societies of Neuropsychopharmacology Mood Disorders, these not well applied psychiatrists throughout nation. To address this issue, we developed ‘Effectiveness Guidelines Dissemination Education in Psychiatric Treatment (EGUIDE)’ integrated education programs to disseminate clinical guidelines. Additionally, conducted a systematic efficacy evaluation...
We examined the relationship between four vegetation indices and tree canopy phenology in an evergreen coniferous forest Japan based on observations made using a spectral radiometer digital camera at daily time step during 4 year period. The colour of surface Japanese cedar (Cryptomeria japonica) changed from yellowish-green to whitish-green late May July turned reddish-green winter. normalized difference index (NDVI), enhanced (EVI) plant area (PAI) showed no seasonality. In contrast,...
