  4. 3. Optimised PCR protocol for ten microsatellite primers (SSRs) in Fragaria vesca : Facilitating future work analysing genetic diversity and developing efficient conservation strategies

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Lisa Haglund; [2022]
    Keywords : Crop wild relatives CWR ; PCR; Microsatellites; Fragaria vesca; Conservation; Genetic diversity;

    Abstract : The world faces severe challenges in providing food security for a growing world population during climate change. This puts pressure on modern agriculture, including adapting crops to new environments and cultivation on less acreage. The tools for adapting crops exist within a species' genetic diversity.

  5. 4. Echo of the Ancients: Evolution of Song in the Avian Family Cettiidae

    University essay from Uppsala universitet/Paleobiologi

    Author : Jared Goodstadt; [2022]
    Keywords : Cettiidae; song; acoustic analysis; PCA; Mahalanobis distance; phylogeny;

    Abstract : The Cettiidae, a family of primarily small, insectivorous, Asiatic and Austronesian, mountain birds have been the subject of acoustic analysis in the past. However, until this point, an in-depth review of the songs of the entire family had yet to be undertaken. READ MORE

  6. 5. Development of a DNA barcode for species identification of tuna

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Clara Nordquist; Jonathan Edwall; Leonora Eriksson; Nelly Mäkinen; Minna Sayehban; Matilda Styfberg; [2022]
    Keywords : Thunnini; D-loop; mitochondrial control region; CR; 16S; ATP8; COII; Cox2; CytB; COI; Cox1; ND2; NADH dehydrogenase 2;

    Abstract : Today, DNA-barcoding with the gene COI is regularly used in the identification of fish. However, this is not an adequate way of identifying species of tuna due to COI lacking sufficient interspecies divergence. This is problematic since fraud and mislabeling are a major concern within the fish and tuna industries. READ MORE
