  1. 11. Analyzing the use of Humidity Cue in Navigation of Drosophila melanogaster

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Kalle Andersson; [2022]
    Keywords : Technology and Engineering;

    Abstract : Humidity is one of the main abiotic factor of ecosystems and affects animals behaviour, fitness and distribution. Due to their small size and inability to thermoregulate using metabolism, insects, such as the fruit fly Drosophila Melanogaster, are especially reliant on humidity. READ MORE

  3. 12. Assessment of the Agroecological Potential of Biostimulatory Effects : originating from Effective Microorganisms (EM) in terms of Environmental and Socioeconomic Aspects

    Author : Tania Schwarzer; [2022]
    Keywords : effective microorganisms; agroecology; biostimulants; beneficial microorganisms; lactic acid bacteria; bokashi; semi-structured interviews; interpretative phenomenological approach;

    Abstract : Environmental pollution, resource depletion and climate change are related to imbalances in the farming system. Effective microorganisms are seen as a possible solution to these problems. READ MORE

  4. 13. Water quality and organic matter linkages in waters draining arable fields

    University essay from SLU/Dept. of Soil and Environment

    Author : Adam Eriksson; [2021]

    Abstract : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. READ MORE

  5. 14. Biowastes for Plant Production : a guide to plant biostimulants

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Toolie-Mina Anderback; [2021]
    Keywords : biological waste; by-products; organic inputs; fish protein hydrolysate; vermicompost; seaweed extract; fish waste; macro algae;

    Abstract : Biostimulants are a suggested tool to achieve sustainable plant production. These are products sourced from biological processes or extracted from biological material, which induces physiological responses in plants. READ MORE

  6. 15. Context dependent variation in aggression and mating behaviour in the pygmy halfbeak (Dermogenys collettei) : a study of wild population

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Piotr Michalak; [2021]
    Keywords : aggression; animal behaviour; ecology; environment; group size; halfbeak; mating; OSR;

    Abstract : To understand animal behaviour, it is important to consider the environment in which it occurs. The environment, consisting of both abiotic factors and social context, is usually highly variable and leads to variation in individual’s and group’s behaviour. READ MORE
