  1. 6. The use of regurgitated pellets from the great cormorant to detect the presence of the round goby

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Tim Dorup; [2023-08-07]
    Keywords : Invasive species; Regurgitated pellets; Great cormorant; Round goby; dPCR;

    Abstract : The round goby (Neogobius melanostomus) is an invasive alien species that poses one of the greatest threats to biodiversity and ecosystem services in Sweden today. The round goby originates from the Black Sea and Caspian Sea but has in recent decades rapidly spread with global shipping traffic to new areas in Europe and North America. READ MORE

  3. 7. Analysis of relatedness and genetic diversity in Swedish sheep breeds using medium density (50K) SNP data

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

    Author : Krishani Devika Wijesinghe Sinhalage; [2023]
    Keywords : sheep; genetic diversity; population structure; inbreeding; runs of homozygosity; coat colour; MC1R;

    Abstract : The local Swedish sheep breeds belong to a group of sheep breeds known as North European short-tailed sheep breeds. Evaluation of genetic diversity, relatedness, and population structure of local breeds offers crucial metrics to prevent inbreeding depression, genetic erosion, and crossbreeding between locally adapted and exotic sheep breeds since these occurrences can have detrimental effects and ultimately lead to extinction.

  4. 8. Relatedness and diversity in Swedish local chicken breeds using mitochondrial DNA D-loop sequences and SNP data

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

    Author : Esther Taiwo Afolabi; [2023]
    Keywords : chicken; genetic diversity; mtDNA d-loop; SNP; Swedish local chicken breeds;

    Abstract : Genetic diversity is the variation in genetic information carried by individuals within a species or population. This variability plays a crucial role in enabling species to adapt and survive in changing environments and is essential for evolutionary processes. READ MORE

  5. 9. Parentage Assignment using genetic markers in the common carp (Cyprinus carpio)

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

    Author : Sven Kristian Feddersen; [2023]
    Keywords : single nucleotide polymorphism; Parentage Assignment; aquaculture; genetic markers;

    Abstract : This study investigated the effect of varying single nucleotide polymorphisms (SNPs) marker density, error threshold selection, and different SNP selection strategies on parentage assignment accuracy in carp populations. Using a marker set of 15,615 SNPs, we found a positive correlation between the quantity of SNP markers and the accuracy of parentage assignments, consistent with existing literature. READ MORE

  6. 10. 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.
