1. 1. 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

   Abstract : Boreal forests are particularly vulnerable to climate change, experiencing a much more drastic increase in temperatures and having a limited amount of more northern refugia. The trees making up these vast and important ecosystems already had to adapt previously to environmental pressures brought about by the repeated glaciations during past ice ages. READ MORE

4. 3. Structural variation identification in non-reference cattle breed genomes

   University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

   Author : Jenny Jakobsson; [2021]
   Keywords : ;

   Abstract : Cattle are essential for the global food industry through the meat and milk production. It is from an economical point of view in our best interest to make cattle as efficient as possible, whether it is milk or beef production, without negatively influencing their health and welfare.

5. 4. Who calls the African Wild Dog? : de novo SNP discovery and genotyping in the Lycaon pictus

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

   Author : Mathilda Bertills; [2021]
   Keywords : snp; single nucleotide polymorphism; african wild dog; lycaon pictus; conservation;

   Abstract : Large carnivores, especially the African wild dog, Lycaon pictus, are vulnerable to human-mediated changes and climate effects. As they are apex predators, they also affect lower trophic levels. Due to anthropogenic land-use changes affecting habitat, prey, and population densities, large carnivore populations are declining.

6. 5. De novo SNP Discovery in the Spotted Hyena (Crocuta crocuta)

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

   Author : Amber Mertens De Vry; [2021]
   Keywords : single nucleotide polymorphism; SNP; spotted hyena; Crocuta crocuta; relatedness; genetic monitoring;

   Abstract : Relatedness studies of wild populations using reliable high-quality genetic markers enhance our understanding of a species’ behavior and ecology. Spotted hyenas (Crocuta crocuta) have a matriarchal social structure, unique amongst carnivores. READ MORE
