  1. 1. SOIL GROSS NITROGEN MINERALISATION AND FOREST GROWTH IN FOUR HEMIBOREAL FOREST STANDS IN SOUTHWEST SWEDEN

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Linnéa Eriksson; [2023-04-20]
    Keywords : soil C:N; forest production; 15N isotope dilution; gross N mineralisation; ammonium; soil carbon; soil nitrogen; root exudates; stoichiometric decomposition; boreal forests; priming; microbial C limitation;

    Abstract : Boreal and temperate forests together make up the largest terrestrial net C sink in the world. They take up carbon dioxide (CO2) from the atmosphere and store it in plant biomass and soil as they grow, making them crucial in mitigating global climate change. READ MORE

  3. 2. Storage of poultry manure in containers : changes in physiochemical parameters and survival of intestinal bacteria

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Homayoon Davam; [2022]
    Keywords : Enterobacteriaceae; Salmonella; composting; straw; litter decontamination; chicken manure;

    Abstract : High nutrient content of chicken litter has made it one of the best organic fertilizers for agricultural land. However, reusing poultry litter in agriculture can be associated with food-borne pathogens such as E.coli, Salmonella and Campylobacter. READ MORE

  4. 3. Reindeer decrease soil carbon stocks and deplete labile soil carbon

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

    Author : Josua Seitz; [2022]
    Keywords : Reindeer; SOC; soils; Finnland; 13C NMR;

    Abstract : Reindeer have been shown to alter boreal ecosystems by changing the vegetation cover and influencing belowground processes. By providing nutrients for plants and by exerting trampling stress on the field layer vegetation, reindeer induce shifts in the vegetation where ground-lichen are being replaced by evergreen shrubs.

  5. 4. Effects of plastic pollution on leaf litter decomposition in Swedish freshwater ecosystems : a field study addressing recently and globally emerging pollutants

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Martina Stangl; [2022]
    Keywords : Microplastics; Face masks; Ecosystem functioning; Leaf decomposition; Field study;

    Abstract : Plastic pollution is recognized as an increasing environmental problem, but few studies have addressed impacts on ecosystem functions, and very few have been conducted in the field. This study investigated the effects of polypropylene particles derived from disposable face masks on in-situ leaf litter decomposition processes in freshwater ecosystems. READ MORE

  6. 5. Effects of native freshwater mussels and leaf debris on benthic macroinvertebrate abundance and diversity : A field experiment with Margaritifera margaritifera in Vasslabäcken, Örebro county

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Kai Sven Onken; [2021]
    Keywords : bivalve; functional role; habitat modification; decomposition; biodeposition;

    Abstract : Organisms that are part of complex ecosystems interact not only with other organisms but also with their environment, affecting ecosystem functions. In aquatic ecosystems filter feeders affect ecosystem functioning by transferring energy and nutrients from the water to the benthos. READ MORE
