    Keywords : Wetlands; GIS; Restoration; Rewetting; Ecology; LONA; Habitats Directive; Natura 2000; Nature conservation; Våtmarker; GIS; Geografiska informationssystem; Restaurering; Återvätning; LONA; Art- och Habitatsdirektivet; Natura 2000; Naturvård;

    Abstract : Located in the borderland between aquatic and terrestrial environments, the wetlands cover a wide spectrum of habitats and enable living standards for a great variety of organisms. Although important habitats, a great extent of the original wetlands have disappeared in Europe and Sweden due to anthropogenic disturbances. READ MORE

  3. 2. The importance of bacterial functional diversity for mixotrophic flagellate function

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Simon Wentritt; [2023]
    Keywords : Mixotrophs; Functional Diversity; Algae Culturing;

    Abstract : This project examined the role of functional diversity of bacterial prey organisms on a mixotrophic flagellate’s function. The concept of functional diversity and its role for ecosystem functioning is a subject of ongoing research and controversially discussed. Mixotrophy is the combination of different modes of nutrition in one organism. READ MORE

  4. 3. Potential migration routes for the alien species, pink salmon (Oncorhynchus gorbuscha) : investigating access in west and south coast rivers of Sweden

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Rebecca Martin; [2023]
    Keywords : invasive; alien species; salmonid; anadromous; migration barriers;

    Abstract : Invasive alien species are one of the main drivers of ecosystem change globally, presenting challenges to biodiversity that take many forms Pink salmon, Oncorhynchus gorbuscha, has recently been observed on the Swedish west coast where its presence is the result of secondary spreading from populations introduced to the White and Barents Seas in northwestern Russia. In Sweden, O. READ MORE

  5. 4. Ecological impacts of dam removal in Swedish inland waters : Effects on water chemistry and fish demography

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Johanna Ekman; [2023]
    Keywords : biology; ecology; dam removal; Sweden; impact; inland waters; ecosystem; water chemistry; fish demography; Perca fluviatilis; European perch; biologi; ekologi; dammutrivning; Sverige; påverkan; inlandsvatten; ekosystem; vattenkemi; fiskdemografi; Perca fluviatilis; abborre;

    Abstract : Dams play an important role in our society, but their negative impacts on aquatic ecosystems have led to a need for conservation efforts to mitigate the negative effects. In some instances, dam removal has been suggested to be the most economically and ecologically beneficial restoration method to improve longitudinal connectivity. READ MORE

  6. 5. Controls over stream temperature in a northern boreal landscape

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Oskar Damström; [2023]
    Keywords : Aquatic ecosystems; Climate change; Stream warming; Boreal streams;

    Abstract : With widespread increases in air temperature, it is expected that the temperature of aquatic ecosystems will also increase, especially at high latitudes. Warmer streams and rivers could have severe, direct impacts on cold-adapted aquatic fauna but may also indirectly influence species by reducing the amount of suitable habitat. READ MORE
