1. 6. Humpback whale (Megaptera novaeangliae) location in Southeast Alaska : modeling the influence of mesoscale krill (Euphausiacea) patch depth and size

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Christine Walder; [2018]
   Keywords : physical geography and ecosystem analysis; humpback whales; krill; patchiness; vertical distribution; Generalized Additive Models GAMs ; spatial modeling; Earth and Environmental Sciences;

   Abstract : Humpback whales ([i]Megaptera novaeangliae[/i]) require dense prey aggregations due to the high energetic cost of their feeding methods. Modeling studies have shown that when whales are on their feeding grounds, they are closely associated with high prey concentrations. READ MORE

3. 7. Sustainable Forestry? : A Sustainability Analysis of the Swedish Forest Sector Applying 'Backcasting from Sustainability Principles' as the Methodology

   University essay from KTH/Miljöstrategisk analys (fms)

   Author : Victoria Ronge; [2017]
   Keywords : Framework for Strategic Sustainability; Sustainability Principles; Backcasting from principles; Backcasting from scenarios; Swedish Forest Sector; Clear-cutting; Continuous Cover Forestry; Environmental Objectives; UN Sustainable Development Goals; National Forest Program; Ramverket för strategisk hållbar utveckling; Hållbarhetsprinciper; Backcasting från principer; Backcasting från scenarier; Svenska skogssektorn; Kalhuggning; Trakthyggesbruk; Kontinuitetsskogsbruk; Hyggesfritt skogsbruk; Svenska miljömålen; FNs Hållbarhetsmål; Nationella skogsprogrammet;

   Abstract : Forests are key providers of terrestrial ecosystem services such as climate regulation, water purification, natural pest control, habitats for biodiversity, as well as different forms of wood based materials and food. Nevertheless forests are dangerously exposed to great pressures from various kinds of societal activities. READ MORE

4. 8. Spatial Modeling of Wildlife Crossing:GIS-based Approach for Identifying High-priority Locations of Defragmentation across Transport Corridors

   University essay from KTH/Geoinformatik

   Author : Josefine Jonsson; [2017]
   Keywords : wildlife crossing; GIS; Circuit Theory; habitat; defragmentation;

   Abstract : In this report, connectivity modeling has been performed using land cover data to find habitat pinch-points for deer along the study area Norrortsleden in Stockholm. Norrortsleden was chosen because there are a high number of deer accidents in the area, and is a priority area for action according to a barrier analysis for deer made by the Swedish Transport Administration.

5. 9. Deforestation patterns and hummingbird diversity in the Amazon rainforest

   University essay from Stockholms universitet/Institutionen för naturgeografi

   Author : Felicia Labor; [2016]
   Keywords : Landscape fragmentation; deforestation; extinction debt; hummingbirds; biodiversity database; spatial landscape analysis; the Amazon rainforest; land-cover change.;

   Abstract : In recent decades expanding land-use change has caused extensive deforestation of the tropical rainforestinducing large-scale transformation of the landscape patterns across the South American continent. Landscapechange is a modification process of the natural forest cover into fragments which generate various ecologicalimpacts. READ MORE

6. 10. 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
