1. 36. Beach-cast fertilizers for cultivation of carrots and radishes on Swedish Gotland : The effect on crop size and nutrient composition

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Sofie Ögren; [2020]
   Nyckelord :Eutrophication; marine biofertilizer; beach-cast management; nutrient analysis; NMR;

   Sammanfattning : In the eutrophicated Baltic, algal blooms with toxin-producing algae and plant overgrowth is a large threat to the marine environment, humans and animals. The use of external nutrient inputs into agriculture, such as mineral fertilizers (NPK), is reaching the Baltic through runoff which causes a constant, linear nutrient flow from land to the sea, which is one of the main contributors to accelerated eutrophication.

3. 37. Spatial patterns of zooplankton communities In Swedish mountain and boreal lakes.

   Kandidat-uppsats,

   Författare :Juan Manuel de la Quintana; [2020]
   Nyckelord :Lake; zooplankton; phytoplankton; DOC and DIN:TP.;

   Sammanfattning :     Zooplankton is crucial for lake ecosystems as it is an important component in most of the food webs of these ecosystems. However, environmental changes have caused reductions in ecosystems nutrients and stoichiometry, which directly affects phytoplankton’s development and quality. LÄS MER

4. 38. A remote-sensing approach to studying drought resistance in Swedish old-growth and production forests

   Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

   Författare :Julika Wolf; [2020]
   Nyckelord :Physical Geography and Ecosystem Analysis; drought impacts; old-growth forests; forest management; remote sensing; Earth and Environmental Sciences;

   Sammanfattning : Boreal forest ecosystems are predicted to experience hotter and drier summers due to climate change, leading to more frequently reduced soil water availability and an increased risk of droughts, as was already the case in Northern Europe during the severe summer drought of 2018. Prolonged water stress in forest ecosystems can lead to impacts ranging from reduced photosynthesis to forest dieback. LÄS MER

5. 39. Analysis of chlorophyll synthesis mutants xantha-m and xantha-j of Hordeum vulgare L.

   Kandidat-uppsats, Lunds universitet/Examensarbeten i molekylärbiologi

   Författare :Fredrik Klinghammer; [2020]
   Nyckelord :Biology and Life Sciences;

   Sammanfattning : The xantha phenotype of barley is observable as a yellow plant and caused by an inability to correctly synthesize chlorophyll. Chlorophyll is a tetrapyrrolic pigment containing magnesium, and is integral for photosynthesis in plants. LÄS MER

7. 40. Urban Farming: Production comparison of Basil and Oak Leaf lettuce in two hydroponic growing systems : an industrial collaborated study in Sweden

   Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

   Författare :Omer Hafeez Malik; [2020]
   Nyckelord :Hydroponics; Lactuca sativa; Ocimum basilicum; precision farming; vertical farming;

   Sammanfattning : The modern agriculture of the world is facing huge challenges in terms of increasing scarcity of natural resources such as water and land. The increase in global population is not only enabling in expansion of big cities but also raising questions of accommodating and feeding this amount of population. LÄS MER
