| The objective of this study was to improve existing methods for determination of stem biomass in a non-destructive way, and verify the influence that laser dendrometers have on the prediction by existing empirical models in forest environment on the individual trees. This study was developed in Itatinga, SP, Brazil, in three plots of a Eucalyptus grandis plantation, totalizing 175 trees. The stem diameter of standing trees were measured with two dendrometers, Criterion and RC3H, along the stem up to 8 meters height. After the volume evaluation of standing trees they were felled and the diameter obtained with a caliper and a tape in the same positions in which the non-destructive measures were taken. Wood disks were removed and dried for determination of... |

| Terrestrial and marine biodiversity provides the basis for both ecosystems functioning and numerous commodities or services that underpin human well-being. From several decades, alarming trends have been reported worldwide for both biodiversity and ecosystem services. Therefore the sustainable management of biodiversity requires a double viewpoint balancing ecological conservation with the welfare of human societies. Understanding the underlying trade-offs, synergies and interactions imposes the development of interdisciplinary researches and methods. In that respect, bio-economic or ecological economic modeling is likely to play a major role. The present paper intends to elicit the key features, strengths and challenges of bio-economic approaches... |
