1. 21. Rehabilitation in a tropical secondary rain forest in Malaysian Borneo : early effects of canopy properties on light conditions at the forest floor

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Joakim Jansson; [2015]
   Keywords : tropisk sekundär regnskog; Dipterocarpaceae; krontäckning; ljus; densiometer; luckor; hemisfäriska foton; tropical secondary rainforest; openness; canopy; light; gaps; visible sky; hemispherical photographs; Crown Illumination Index; densiometer;

   Abstract : Tropisk regnskog i Sydostasien är ett av de områden som hyser störst biodiversitet i världen, av vilken stora ytor är hotat. Ön Borneo drabbades av en katastrof åren 1982-1983 efter att väderfenomenet El Niño orsakat torka med vidsträckta skogsbränder som följd. READ MORE

3. 22. Testing the robustness of the Plant Phenology Index to changes in temperature

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Iain Lednor; [2015]
   Keywords : NDVI; Plant Phenology Index; physical geography and ecosystem analysis; remote sensing; EVI2; Vegetation Index; temperature; phenology.; Earth and Environmental Sciences;

   Abstract : Traditional vegetation indices have long encountered a problem of saturating at high biomass levels. A newly formulated vegetation index, the Plant Phenology Index (PPI), which has a near linear relationship with canopy green leaf area index (LAI) is tested in this study against temperature at 12 sites across Sweden.

4. 23. Impacts of Climate Change on Abies spectabilis : an approach integrating a Species Distribution Model (MaxEnt) and a Dynamic Vegetation Model (LPJ-GUESS)

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Mohan Dev Joshi; [2015]
   Keywords : MaxEnt; Manaslu conservation area; GEM; Abies spectabilis; Physical Geography and Ecosystem Analysis; climate change; LPJ-GUESS; Earth and Environmental Sciences;

   Abstract : Recent global warming trends, particularly in the arctic regions and Himalayas are modifying forest structure and function, notably biogeographical changes in tree species distribution together with alteration in Net Primary Production (NPP), Leaf Area Index (LAI) and Carbon biomass. These alterations are most pronounced in mountain environments, carrying significant impacts on woody species which are more sensitive to temperature changes. READ MORE

5. 24. Att sänka temperaturer i stadsmiljö : en studie av trädens effekt på en bostadsgård i Malmö

   University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

   Author : Linnea Saarela; [2014]
   Keywords : urban heat island; solstrålning; albedo; skugga; evapotranspiration; mikroklimat; ENVI-met; LAI; LAD;

   Abstract : Under de senaste årtiondena har det pågått en förtätning och en alltmer ökad utbyggnad av världens städer. Som en följd av detta har stadens naturliga vatten- och värmebalans rubbats. På bekostnad av vegetativa ytor har artificiella byggmaterial introducerats som absorberar värme från solens strålar och höjer stadens temperaturer. READ MORE

6. 25. Functional diversity of evertebrates in different types of beech forest in southern Sweden

   University essay from Lunds universitet/Examensarbeten i biologi

   Author : Martin Larsson; [2014]
   Keywords : Biology and Life Sciences;

   Abstract : Abstract Deforestation, fragmentation and loss of biodiversity, all are elements that are common today. With this project I want to evaluate if there is a difference in functional diversity of evertebrates between beech stands of low herb and shrub type beech forest. READ MORE
