Airborne lidar (Light Detection And Ranging) is a proven technology that can be used to accurately assess aboveground forest biomass and bio-energy feedstocks. The overall goal of this study was to develop a method for assessing aboveground biomass and component biomass for individual trees using airborne lidar data in forest settings typical for loblolly pine stands (Pinus taeda L.) in the sou...
Little information is available on the effects of applying compost tea to species in dry regions. Compost from agricultural waste can promote drought resistance in plants and increase their growth by improving soil structure and providing nutrients and enhancing the capacity of the soil to store moisture. In order to examine these effects, compost tea was tested on two species growing in dry re...
BACKGROUND AND AIMS Root cortical aerenchyma (RCA) increases water and nutrient acquisition by reducing the metabolic costs of soil exploration. In this study the hypothesis was tested that living cortical area (LCA; transversal root cortical area minus aerenchyma area and intercellular air space) is a better predictor of root respiration, soil exploration and, therefore, drought tolerance than...
The movement capacity of the crown-of-thorns starfishes (Acanthaster spp.) is a primary determinant of both their distribution and impact on coral assemblages. We quantified individual movement rates for the Pacific crown-of-thorns starfish (Acanthaster solaris) ranging in size from 75-480 mm total diameter, across three different substrates (sand, flat consolidated pavement, and coral rubble) ...
The continuous extraction of an amino acid from aqueous solution into ionic liquid phase was studied experimentally in small channels, demonstrating a double intensification the solvent used and overall process. Channels with 0.5, 1 2 mm internal diameter were for acid, L-tryptophan (0.005 mol L?1), hydrophobic liquid, 1-Butyl-3-methylimidazolium Bis (trifluoromethanesulfonyl)imide, [C4mim][Tf2...
Predicting the volume and biomass of multi-stem maple trees (Acer monspessulanum Subsp. cinerascens Boiss.) based on standing traits is necessary in forestry. In this research twenty sample trees were selected in four transects randomly in Bagh-Shadi Forest of Yazd province. After measuring the diameter at root collar (DRC), tree height, stems numbers and crown diameter and area all trees were ...
Tree parameter determinations using airborne Light Detection and Ranging (LiDAR) have been conducted in many forest types, including coniferous, boreal, and deciduous. However, there are only a few scientific articles discussing the application of LiDAR to mangrove biophysical parameter extraction at an individual tree level. The main objective of this study was to investigate the potential of ...
