2010 2010 IEEE International Geoscience and Remote Sensing Symposium  
This paper has demonstrated that an estimation approach to the retrieval of forest parameters is possible for Brigalow dominated regrowth, but the method could equally be applied to other forest types  ...  In order to retrieve parameters from the SAR data it is assumed σ 0 can be expressed as closed form parametric equations relating total backscatter to a small number of unknowns, describing forest structure  ...

Current remote sensing approaches to monitoring forest degradation in support of countries measurement, reporting and verification (MRV) systems for REDD+

Anthea L. Mitchell, Ake Rosenqvist, Brice Mora
2017 Carbon Balance and Management  
Improvements in the reliability of mapping methods are anticipated by SAR-optical data fusion and use of very high resolution data.  ...  There has been progress in the capacity to discriminate forest age and growth stage using data fusion methods and LiDAR height metrics.  ...  Publisher's Note Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.  ...

Assessing and mapping of carbon in biomass and soil of mangrove forest and competing land uses in the Philippines

Jose Castillo, Armando Apan, Maraseni Tek
In the third objective, the soil C stocks of the study land uses were quantified to estimate C losses in soil owing to conversion.  ...  However, the SAR-based model was more accurate in predicting the biomass in the usually deficient-to-low vegetation cover replacement land uses.  ...  The generated information can also be used as an empirical basis to estimate emissions from land use change and forest degradation in mangrove.  ...

In addition to their primary functions in photosynthesis, carotenoids play essential roles in plant reproduction by furnishing flowers and fruits with distinct pigmentation and as precursors for volatiles  ...  Light microscopy (eosin and hematoxylin staining) and confocal microscopy (Hoechst 33342, acridine orange and propidium iodide staining) were used to evaluate the mechanism of action of the acetone leaf  ...  We also used carbon stock data from restored and intact sites, and sampled carbon stocks at restored stands at a second site in the same thicket plant community.  ...
