Summary Ecological measurements should be arranged in order to obtain the necessary, and only the necessary, information, for the testing of hypothesis. A careful analysis of measuring procedure provides means for economizing measuring work. For such

A system for measuring the net photosynthesis, transpiration and environmental factors within the canopy and ground cover vegetation is described. The system operates continuously throughout the growing season in a young Scots pine ( L.) stand. A dat

This paper describes an impulse (short pulse) radar with high distance resolution. The radar is intended for short-range (< 2 m) detection of subsurface objects or boundaries. The primary application is detection of rot in 1iving trees and power or t

Light intensity inside the canopy varies considerably both in space and time. A new apparatus was developed which is disturbed as little as possible by the above-mentioned variation. The construction is based on the linear relationships between light

SUMMARY A measuring system for estimating the frequency distributions of irradiance within a stand is described. The instrument uses a distributed set of thirty-two sensors to measure both temporal and spatial variations in irradiance in a canopy. It

SUMMARY (1) A method is described which estimates the photosynthetic products which are available for the growth of a plant within a canopy. (2) The basic assumptions are: (i) a plant can be treated as an integrator of the curvilinear relationship of
