  1. 1. Plant phenology and climate change : possible effect on the onset of various wild plant species first flowering day in the UK

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Nigel Fox; [2019]
    Keywords : geography; GIS; plants; phenology; climate change; global warming; FFD; IPCC; Bluebell; Garlic mustard; Coltsfoot; Cuckooflower; United Kingdom; Woodland Trust; UK; Earth and Environmental Sciences;

    Abstract : The IPCC states that the planet is significantly warming due to effects of climate change. This warming effect has consequences for phenological events. Many species cannot track rapid climate change, resulting in phenological mismatches. This study looks at an extreme weather event and the longer-term effects of climate change. READ MORE

  2. 2. Many pathways to sustainability? A critical analysis of sustainable development narratives in the UNEP Global Environmental Outlook series

    University essay from Malmö universitet/Kultur och samhälle

    Author : Laura Verbrugge; [2019]
    Keywords : discourse; environmental assessment; UNEP; sustainable development; traditional knowledge;

    Abstract : Sustainable development has become a leading term in global environmental policy and aims to integrate social, economic and environmental goals in development. However, it is a term that is also much debated, as it does not clearly define what sustainability is and how to get there. READ MORE

  3. 3. Implications of a dynamic vertical root distribution for modelled water and carbon fluxes across selected ecosystems : incorporating a novel rooting scheme into LPJ-GUESS

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lasse Keetz; [2019]
    Keywords : Physical Geography and Ecosystem Analysis; Ecosystem Modelling; LPJ-GUESS; Vertical Root Distribution; Dynamic Root Distribution; Carbon and Water Fluxes; Earth and Environmental Sciences;

    Abstract : Roots play a key role in terrestrial carbon and water cycles, and therefore for the global climate system. They mediate plant evapotranspiration, influence photosynthetic processes and are responsible for atmospheric carbon transport into the pedosphere. Fine roots, in particular, are chiefly regulating water and nutrient uptake. READ MORE

  4. 4. Impact of environmental variables on tundra vegetation onset of flowering explained by survival modelling

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Hanna Jonsson; [2019]
    Keywords : Flowering; Phenology; Cox proportional hazard model; Tundra; International tundra experiment; Climate change; Physical Geography and Ecosystem analysis; Earth and Environmental Sciences;

    Abstract : Timing of phenological events are highly related to climate and is one of the first signs of ecosystem responses to the climate change. Timing of flowering phenology is an important trait influencing the distribution and fitness of plants species. READ MORE

  5. 5. Planning for Viable Forests with High Biodiversity

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Keywords : Anja Herdesang; Planning for Viable Forests with High Biodiversity; forestry; foresters; forester; biodiversity; ecosystem; forest; sustainability; extinction; speices; refinement; nature; clear-cut; cuts; monocultured; forests; alternative; concervation; enviromental laws; even-aged; continuous; silvicultural; wood products; cost-effectiveness; Protection; timber; pulp; production; forest owners; harvesting; red-listed; violations; protected; effective management; ecosystem responses; disturbance; Cross-disciplinary cooperation; climax and carrying capacity; index; describing the abiotic basic Prerequisites for Biodiversity APB ; guideline; trees connected; wildlife connectivity; continuity; Earth and Environmental Sciences; Agriculture and Food Sciences; Biology and Life Sciences; Cultural Sciences; Law and Political Science;

    Abstract : In recent decades, the rate of extinction of species is increasing due to human use and refinement of nature. This has resulted in a large amount of research throughout the world. Forestry today is mostly based on clear cuts, and many natural forests have been cut down and replaced with monocultured forests. READ MORE
