  1. 1. Diving Deep: Seabird foraging tactics and local prey field

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Elin Andersson Sjöholm; [2024]
    Keywords : Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

    Abstract : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. READ MORE

  3. 2. 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

    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

  4. 3. Sensitivity of Norway Spruce (Picea abies) to inundation.

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

    Author : Whitney Cleopatra Vlahakis; [2023]
    Keywords : Inundation; riparian zone; spruce seedlings; restoration; mortality;

A key characteristic that differentiates riparian zones from adjacent aquatic and terrestrial environments is the event of periodic flooding and water logging. READ MORE

  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
