  1. 1. Headfirst into shallow water - Wetland restoration and its contribution to the Habitats Directive

    University essay from Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Elin Brandt Korall; [2024]
    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. Predicting Chemical-Gene Interactions

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Ali Chishti; [2023-08-04]
    Keywords : Pesticides; Small streams; Prediction modelling; Chemical-protein-gene interactions; Aquatic organisms;

    Abstract : Pesticide use in agriculture has become a growing concern as it can have detrimental effects on the environment. The excessive use of these chemicals often leads to them seeping into nearby water bodies, causing harm to aquatic organisms. READ MORE

  4. 3. Ecological risk assessment of pesticide use in rice farming in the Mekong Delta , Vietnam

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Bubaraye Ohiosimuan Dirikumo; [2023]
    Keywords : Pesticides; Ecological Risk Assessment ERA ; rice farming; Mekong Delta; PRIMET Model; Exposure Toxicity Ratio ETR ; species sensitivity distribution SSD ; predicted environmental concentrations PECs ;

    Abstract : Pesticide use in rice farming is a common practice in the Mekong Delta and poses ecological risks to aquatic organisms, the environment, and human health. This study focused on the ecological risk assessment of pesticide use in rice farming using the PRIMET model as a decision support tool to evaluate the risks of pesticide exposure, ecotoxicity, and risk characterization, as well as employing the species sensitivity distribution (SSD) assessment model to calculate the potentially affected fraction (PAF) of species based on the computed predicted environmental concentrations (PECs) from PRIMET.

  5. 4. 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

  6. 5. Vattenföroreningars påverkan på biologisk mångfald och abundans hos akvatiska evertebrater : en studie i södra Sverige

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Sandra Wiig; Sara Åsberg; [2023]
    Keywords : Abundans; akvatiska evertebrater; biodiversitet; reningsverk; vattenkvalitet;

    Abstract : Föroreningar i landskapets vatten kan spridas genom många olika faktorer, exempelvis via reningsverk, skogsbruk och jordbruk. De organismer som lever i vattenmiljöer kan vara mycket känsliga för de föroreningar som släpps ut, vilket kan leda till allvarliga konsekvenser som förlust av biologisk mångfald och andra förändringar inom dessa samhällen.
