1. 6. Analysis of Arctic peak-season carbon flux estimations based on four MODIS vegetation products

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Antonin Kusbach; [2016]
   Keywords : satellite-derived data; vegetation indices; Arctic; net ecosystem exchange; big data analysis; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

   Abstract : Increased temperatures in high latitudes may alter the carbon dynamics throughout the Arctic. Modelled CO2 simulations show that current climate conditions constitute the Arctic a net carbon sink, though the large extent and fine landscape heterogeneity raise an uncertainty about the carbon sink/source status of the region.

3. 7. Effects of altered precipitation regimes on bryophyte carbon dynamics in a Peruvian tropical montane cloud forest

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Jenny Ahlstrand; [2016]
   Keywords : precipitation; tropical mountain cloud forest; Bryophytes; Peru; carbon dynamics; physical geography and ecosystem science; Earth and Environmental Sciences;

   Abstract : Tropical montane cloud forests (TMCF) are unique ecosystems that are frequently surrounded by clouds which increase humidity and promote the growth of bryophytes. Several dimensions of humidity are important for the carbon dynamics of bryophytes. Climate change is therefore projected to have a large impact on them as well as on the TMCF itself. READ MORE

4. 8. Organic farming’s role in adaptation to and mitigation of climate change : an overview of ecological resilience and a model case study

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Gusten Brodin; [2016]
   Keywords : sustainable agriculture; soil carbon sequestration; organic farming; climate change resilience; LPJ-GUESS; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

   Abstract : Agriculture is essential for human survival and today it faces many problems related to both climate change and an increasing population. While increased total yields during the 20th century have created the conditions for both global economic and population growth, the agricultural practices utilized have often had detrimental consequences both for ecosystems and people.

5. 9. Bird biodiversity in relation to forest composition in Sweden

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Annabelle Finck; [2015]
   Keywords : timber production; bird biodiversity; indicator species; forest composition; bird occurrence; Physical Geography and Ecosystems Science; Earth and Environmental Sciences;

   Abstract : The large development of timber activities in Sweden has induced important changes in forest composition. Today they are less old, deciduous trees and snags in Swedish forests. Such changes threaten the survival of certain bird species in Sweden. READ MORE

6. 10. The survival of moth larvae feeding on different plant species in northern Fennoscandia

   University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Author : Ulrika Belsing; [2015]
   Keywords : winter moth; ecosystem analysis; physical geography; autumn moth; northern Fennoscandia; outbreaks and sub-arctic environment; Earth and Environmental Sciences;

   Abstract : Northern Fennoscandia belongs to the sub-arctic environment and its forests are mostly composed of mountain birch trees (Betula pubescens ssp. czerepanovii). READ MORE
