1. 1. Estimating above ground biomass in a Salix plantation using high resolution UAV images

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Simon Nåfält; [2018]
   Keywords : biomass; Salix; structure from motion; unmanned aerial vehicle; allometry; point cloud; Earth and Environmental Sciences;

   Abstract : In forest biomass estimations, three dimensional (3D) canopy structure data derived from images captured by unmanned aerial vehicles (UAVs), also known as drones, has shown potential due to the flexibility and cost efficiency of the method. However, little research has been done for its applicability in bioenergy forest. READ MORE

3. 2. Biofuel plantations and isoprene emissions in Svea and Götaland

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Zahra Khais Shahid; [2017]
   Keywords : Isoprene; Geographical Information Systems GIS ; Short Rotation Coppice SRC ; Nitrogen dioxide NO2 ; biofuels; Earth and Environmental Sciences;

   Abstract : Bioenergy as an alternative source for energy production and transportation has gained attention to mitigate greenhouse gas emissions from fossil fuels. Short Rotation Coppice (SRC) as dedicated energy crops for heat and energy production have many demonstrated and proved climatic, biodiversity and environmental benefits, but concerns regarding the occurred Land Cover Change (LCC) from agriculture land into SRC have been raised.

4. 3. Biogenic volatile organic compound emissions from Willow trees

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Md. Ahsan Mozaffar; [2013]
   Keywords : atmosphere; Salix; Willow; biogenic volatile organic compounds; Isoprene; climate; BVOC; geography; physical geography; Earth and Environmental Sciences;

   Abstract : In August 2012, emissions of biogenic volatile organic compounds (BVOCs) from willow (Salix) trees were measured in Lund, southern Sweden. Sweden has more than 16000 ha of short rotation willow plantations for biofuel production and willow trees are suspected to emit substantial amounts of BVOC to the atmosphere. READ MORE

5. 4. Emissions of biogenic volatile organic compounds in a Salix biofuel plantation : field study in Grästorp (Sweden)

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Malin Broberg; [2013]
   Keywords : Salix; biogenic volatile organic compounds; BVOC; willow; atmosphere; soil; physical geography; Earth and Environmental Sciences;

   Abstract : Biogenic volatile organic compounds (BVOCs) play an important role in the climate system by altering the oxidative capacity of the atmosphere, affecting the lifetime of methane and production of tropospheric ozone, and by contributing to formation of aerosols and clouds. Salix plants (willows) are well-documented emitters of BVOCs and this study aims to examine emissions in a Salix biofuel plantation for a better understanding of its total climate impact. READ MORE

6. 5. Abundance of syrphid larvae in willow plantations : role of habitat type, prey (Phratora vulgatissima) availability and interactions with other natural enemies

   University essay from SLU/Dept. of Ecology

   Author : Hans Johansson; [2009]
   Keywords : intraguildpredation; hover fly; foraging behaviour; heteropteran; willow plantation; surrounding habitat; biocontrol; leaf-beetle; mirid; anthocorid;

   Abstract : A large number of hover fly species are as larvae effective predators and often feed on insect pests in plantations. The leaf-beetle Phratora vulgatissima is a common pest in willow plantations and the aim of this study is to study what may affect the presence of hover flies in this system. READ MORE
