  1. 1. IDENTIFICATION OF ENVIRONMENTALLY RELEVANT BENTHIC FORAMINIFERA FROM THE SKAGERRAK FJORDS BY DEEP LEARNING IMAGE MODELING

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Marko Plavetic; [2023-06-26]
    Keywords : benthic foraminifera; deep learning; environmental monitoring; YOLOv7;

    Abstract : Over the several past decades, there has been increasing interest in using foraminifera as environmental indicators for coastal marine environments. As compared to macrofauna, which are currently used in environmental studies, foraminifera offer several distinct advantages as bioindicators, including short generation times, a high number of individuals per small sample volume, hard and durable tests with high preservation potential, and low cost of sample extraction.

  3. 2. Vattenföroreningars påverkan på biologisk mångfald och abundans hos akvatiska evertebrater : en studie i södra Sverige

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Sandra Wiig; Sara Åsberg; [2023]
    Keywords : Abundans; akvatiska evertebrater; biodiversitet; reningsverk; vattenkvalitet;

    Abstract : Föroreningar i landskapets vatten kan spridas genom många olika faktorer, exempelvis via reningsverk, skogsbruk och jordbruk. De organismer som lever i vattenmiljöer kan vara mycket känsliga för de föroreningar som släpps ut, vilket kan leda till allvarliga konsekvenser som förlust av biologisk mångfald och andra förändringar inom dessa samhällen.

  4. 3. Uptake and retainment of radionuclides in edible mushrooms – from fruiting to cooking

    University essay from

    Author : Delshad Mansour Ayoubi; [2022-12-06]
    Keywords : Medical physics; Activity concentration; Transfer coefficient; Dose;

    Abstract : Purpose: The purpose of this study was to study the uptake, distribution and transfer of Mn-54, Zn-65, U-238, U-235, U-234, and Po-210 in mushrooms and their respective caps and stalks, the effects of chelates and ligands, and the potential release of radionuclides during a cooking procedure. Introduction: Fungi are organisms that are composed of a fruiting body (mushroom) and tubular hyphae, that branches out into complex networks called mycelium. READ MORE

  5. 4. Common Guillemots Uria aalge Alter Trip Patterns During Breeding

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Mica Bohacek; [2022]
    Keywords : Common Murre; Stora Karlsö; trip duration; trip frequency; central-place foragers; feeding rate; time-budget;

    Abstract : Seabirds are facing immense pressures, primarily induced by competition with commercial fisheries; this is of considerable concern due to the critical role that they play in marine food webs and their invaluable function as bioindicators. In this thesis, I studied the temporal change in trip duration for the Common Guillemot Uria aalge, a circum-arctic seabird species. READ MORE

  6. 5. Using the AudioMoth - a novel passive acoustic monitoring technology - to monitor bat diversity in a rewilded landscape

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Koen Pronk; [2022]
    Keywords : passive acoustic monitoring; bioindicator; chiroptera; audioMoth; trophic rewilding;

    Abstract : Ecosystem restoration through the reintroduction of grazers is gaining interest across Europe. Large herbivores are associated with landscape heterogeneity, restoration of trophic cascades and biodiversity. READ MORE
