  1. 6. Shifts within the carbon cycle in response to the absence of keystone herbivore Ovibos moschatus in a high arctic mire

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Joel White; [2017]
    Keywords : vegetation; carbon; wetland.; methane; Arctic; Physical Geography Ecosystem Science; herbivory; Earth and Environmental Sciences;

    Abstract : Tundra ecosystems are generally recognized as globally important carbon sinks, yet the knowledge on threats to such ecosystems is narrow. Climate change is predicted to reduce the number of muskox (Ovibos moschatus) in the arctic, it is therefore essential to understand the effect herbivores induce on the arctic ecosystem. READ MORE

  3. 7. Feature Selection Methods with Applications in Electrical Load Forecasting

    University essay from Lunds universitet/Matematik LTH

    Author : Oscar Utterbäck; [2017]
    Keywords : Machine Learning; Data Science; Electrical Load Forecasting; Short Term Load Forecasting; Feature Selection; Filter Methods; Mathematics and Statistics; Technology and Engineering;

    Abstract : The purpose of this thesis is two-fold: implement and evaluate a method, the Fast Correlation-Based Filter (FCBF) by Yu et al., for feature selection applied on a meteorological data set consisting of 19 weather variables from 606 locations in Scandinavia, and investigate whether geography can be exploited in the search for relevant features.

  4. 8. Methane flux measurements with low-cost solid state sensors in Kobbefjord, West Greenland

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hanna Axén; [2016]
    Keywords : Geography; Physical Geography; Arctic; Greenland; methane flux; wetlands; instrument; Earth and Environmental Sciences;

    Abstract : Methane is one of the most important greenhouse gases, and the Arctic region plays an important role in its dynamics. Due to limited observations in this remote and often harsh environments, large uncertainties surround the role of the Arctic region in a warming climate. READ MORE

  5. 9. Assessing avalanche risk by terrain analysis : an experimental GIS-approach to The Avalanche Terrain Exposure Scale (ATES)

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Simon Nåfält; [2016]
    Keywords : Altitude; ATES; avalanche; terrain analysis; GIS; Nuolja; Physical Geography and Ecosystem Science; Earth and Environmental Sciences;

    Abstract : This study addresses the complex nature of snow avalanches and how their location can be predicted, and thus avoided, when navigating through mountainous terrain during winter recreations. The avalanche risk in the ski area of Nuolja, in northern Sweden, was evaluated by an experimental implementation of the Avalanche Terrain Exposure Scale (ATES) which is a model for pre-trip planning and assessment of exposure to avalanches.

  6. 10. 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
