   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biofouling; cryopreservation; ecosystem services; environmental impact; extractive aquaculture; gametophytes; kelp; population diversity; Saccharina latissima; seaweed cultivation; selective breeding; site selection;

   Sammanfattning : Seaweed aquaculture is gaining more interest worldwide, including Europe. However, despite its long coast seaweed farming is still very minor in Sweden. LÄS MER

3. 2. Towards a sustainable tilapia breeding program in Tanzania

   Författare :Redempta Athanas Kajungiro; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; AGRICULTURAL SCIENCES;

   Sammanfattning : A structured breeding program is an important step towards sustainable tilapia aquaculture in Tanzania. The aim of the thesis was to generate baseline information for the establishment of tilapia breeding program in Tanzania. LÄS MER

4. 3. Breeding for improved hip and elbow health in Swedish dogs

   Författare :Sofia Malm; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Sammanfattning : Decades of selective breeding to reduce the prevalence of hip and elbow dysplasia(HD and ED) in Swedish dogs, based on phenotypic assessment of radiographic hip status, has had limited success. The prevalence of dysplastic dogs is still high in many large-sized and giant breeds and among the most common causes for euthanasia and costly veterinary care in numerous breeds are joint-related problems.

5. 4. Genetic Aspects of Sexual Selection and Mate Choice in Salmonids

   Författare :Lars Forsberg; Mats Grahn; Jacob Höglund; Claus Wedekind; Uppsala universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Biology; mate choice; Mhc; Major histocompatibility complex; class IIB; disassortative; assortative; microsatellite; outbreeding; supportive breeding; population; population genetics; Biologi; Biology; Biologi;

   Sammanfattning : The long-term genetic consequences of supportive breeding programs are not well understood. Nevertheless, stocking populations with hatchery-produced fish to compensate for losses of natural production are common practice, for example after constructions of hydroelectric power dams.

7. 5. Detecting Signatures of Selection within the Dog Genome

   Författare :Abhirami Ratnakumar; Matthew Webster; Kerstin Lindblad-Toh; Greg Barsh; Uppsala universitet; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; dog; evolution; domestication; PRDM9; recombination; positive selection; selective sweep;

   Sammanfattning : Deciphering the genetic basis of phenotypic diversity is one of the central aims of biological research. Domestic animals provide a unique opportunity for making substantial progress towards this goal. LÄS MER
