For example, stem diameters can be estimated from the TLS point cloud by applying automatic algorithms, which often approximate the stem cross section by using a circle or a cylinder. However, the ...

Leaf N content per unit leaf area (N area, g m-2) was calculated by N m × LMA (n = 6). Leaf photosynthetic pigment analyses Chlorophyll a and chlorophyll b concentrations were quantified from 0.1 g of ...
