  1. 1. Genetisk variation hos lantrashöns : skillnader inom svenska lantraser och europeiska lantraser

    University essay from SLU/Dept. of Animal Breeding and Genetics

    Author : Andrea Hilding; [2023]
    Keywords : genetisk variation; lantras; höns; svensk lantras; Europa;

    Abstract : Detta arbete undersöker hur den genetiska variationen ser ut hos lantrashöns i Sverige och några europeiska länder. Den genetiska variationen är ett mått på vilken nivå av biologisk mångfald som finns inom en art eller population och kan visa på hur inavel tidigare förekommit i populationerna som undersöks.

  3. 2. Understanding Access to Clean Cooking Fuels in Kenya

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Manuel Enrique Salas Salazar; [2023]
    Keywords : ;

    Abstract : Adoption of clean cooking fuels is conditioned by factors known as barriers and enablers, which characterize the decision-making environment of a household. Access to clean cooking is a target part of the Sustainable Development Goals, yet it currently stands at 19.5% in Kenya. READ MORE

  4. 3. Sustainable management of the African elephant – stakeholder solutions to a human-wildlife conflict

    University essay from SLU/Dept. of Anatomy, Physiology and Biochemistry

    Author : Varwi Jacob Tavaziva; [2023]
    Keywords : sustainability; hunting; stakeholders; meat; bees; chillies;

    Abstract : Densities of African elephants have increased in southern Africa, reaching a population size of 45000 in some protected areas such as Hwange National Park, which is beyond the estimated carrying capacity of 15000. The overpopulation of elephants at Hwange National Park has stimulated considerable debates among stakeholders about the effective and sustainable approach to managing elephants. READ MORE

  5. 4. Evolutionary conservation analysis of sequence variants underlying ecological adaptation in Atlantic herring

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Leyi Su; [2023]
    Keywords : Ecological adaptation; Evolutionary conservation; Atlantic herring;

    Abstract : The Atlantic herring (Clupea harengus) is a model organism for exploring the genetic basis of ecological adaptation on account of its large effective population size which greatly restrains the disturbance of genetic drift. In this project, I conducted an evolutionary conservation analysis of the Atlantic herring genome using conservation scores generated by phastCon, phyloP and GERP++ in order to study the sequence variants related to salinity or spawning-time adaptation in Atlantic herring.

  6. 5. Detectability of insects in Malaise traps : assessing insect detectability in Malaise traps through High-Resolution Sampling, and development of a novel marking technique

    University essay from SLU/Dept. of Ecology

    Author : Viktor Gårdman; [2023]
    Keywords : Malaise trap; activity; movement; weather; mark-recapture; detectability; insects;

    Abstract : Malaise traps are extensively used in insect surveys and studies, yet the detectability of insects in relation to the traps remain unknown. Detectability is the odds that a taxon ends up in a trap, given that the taxon is present in the area around the trap. READ MORE
