  1. 1. As I live and breathe! : The effects of hypolimnic oxygenation on benthic macroinvertebrate and zooplankton assemblages

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

    Author : Rashid Kadhim; [2022]
    Keywords : lake hypoxia; benthic macroinvertebrates; chironomids; zooplankton;

    Abstract : Exacerbated deep-water hypoxia, brought about by anthropogenic-derived dissolved organic carbon (DOC) input, has potentially detrimental impacts on organisms residing in freshwater ecosystems. Oxygenation of the water column is a potential management strategy to mitigate this impact, and used to alleviate DOC induced oxygen depletion. READ MORE

  3. 2. Forest Ditches As Habitat For Aquatic Macroinvertebrate In Boreal Landscapes

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

    Author : Lara Sánchez Calderón; [2022]
    Keywords : aquatic macroinvertebrates; drainage ditches; Sweden; mineral soil; peat soil; forestry;

    Abstract : Large areas of northern Sweden have been ditched to promote forest growth by draining wet soils and peatlands. These ditches have greatly added to length of Sweden’s stream and river network, but the ecological properties of these man-made aquatic environments is poorly understood. READ MORE

  4. 3. Stream size determines densities of larger juvenile brown trout in mountain streams

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

    Author : Mattias Melin; [2021]
    Keywords : Habitat availability; juvenile brown trout; stream size; population structure;

    Abstract : The productivity or availability of juvenile habitats have theoretically been shown to determine size distributions of adult individuals and population abundance. Brown trout (Salmo trutta) is a species where adults may inhabit lakes and use connected streams for spawning and as nursery habitats for juveniles. READ MORE

  5. 4. The effects of eutrophication and browning on prey availability and performance of the three-spined stickleback (Gasterosteus aculeatus)

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Olivia Bell; [2021]
    Keywords : Baltic Sea; benthic habitats; body growth; climate change; coastal areas; diet; fish; stickleback; zooplankton;

    Abstract : Shallow coastal areas often have high productivity and diversity, in part due to the high availability of light and nutrients. At the same time, they are exposed to multiple environmental pressures, such as browning and eutrophication. READ MORE

  6. 5. Spatial and temporal variations in stable isotope signatures (δ13C and δ15N) of the gammarids and the common carp in the southern coast of the Caspian Sea

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Nazila Hajizadeh Koupayeh; [2020]
    Keywords : carbon stable isotope; Caspian sea; Cyprinus carpio; food webs; Gammarus aequicauda; nitrogen stable isotope; Pontogammarus maeoticus;

    Abstract : Despite the growing body of research on the use of stable isotope analysis in food web studies, spatial and temporal variations in stable isotope ratios of coastal communities are still poorly understood. The aim of my study is to explore how carbon and nitrogen stable isotopes of selected benthic communities vary spatially and temporally across the south of Caspian Sea. READ MORE
