2. 21. Genetic connectivity of fish in the Western Indian Ocean

   Author : Oskar Henriksson; Mats Grahn; Anders Angebjörn; Filip Volckaert; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; population genetics; indian ocean; siganus sutor; valamugil buchanani; scarus ghobban; connectivity; aflp; mtDNA; d-loop; CO1; zoologisk ekologi; Animal Ecology;

   Abstract : An almost unbroken fringing reef runs along the east coast of Africa, the lagoon inside the reef is the foundation of almost all artisanal fisheries. It is a low-tech fishery conducted by many people. Some areas can have up to 19 fishermen per square kilometer. READ MORE

4. 22. Migration in Prehistory : DNA and stable isotope analyses of Swedish skeletal material

   Author : Anna Linderholm; Kerstin Lidén; Oliver Craig; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Migration; ancient DNA; stable isotopes; δ13C; δ15N; δ34S; mtDNA; lactose tolerance; Neolithic; Pitted Ware culture; Funnel Beaker culture; Vikings; Öland; Rössberga; Birka; Björned; Archaeology; Arkeologi; Archaeological Science; laborativ arkeologi;

   Abstract : The main aim of this thesis is to show how scientific methods may be used to look at migration in prehistory on the basis of archaeological material. The individuals examined represent the period 4 000 BC to 1 000 AD and have their geographical origins in various parts of Sweden.Ancient DNA analysis is employed in three cases. READ MORE

5. 23. Ancient DNA as a Means to Investigate the European Neolithic

   Author : Helena Malmström; Anders Göterström; Gunilla Holmlund; T Brown; Uppsala universitet; []
   Keywords : Molecular genetics; aDNA; contamination; authentication; mtDNA; Neolithisation; Genetik;

   Abstract : The transition from a hunter-gatherer lifestyle to a farming lifestyle, i.e. the Neolithisation, is arguably the most important event in human prehistory. While the geography and dating of the Neolithisation is well known, the process is still under debate, especially if it occurred through diffusion of ideas or with migrating farmers. READ MORE

6. 24. Phylogenetic Relationships of Silene sect. Melandrium and Allied Taxa (Caryophyllaceae), as Deduced from Multiple Gene Trees

   Author : Anja Rautenberg; Bengt Oxelman; Mikael Thollesson; Magnus Lidén; Freek Bakker; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silene; Elisanthe; Melandrium; Conoimorpha; Caryophyllaceae; Silene multinervia; relative dating; extreme substitution rates; phylogeny; BEST; BEAST; cpDNA; mtDNA; RNA polymerase; RPA2; RPB2; RPD2; SlX1; SlY1; ITS; introgression; incongruent phylogenies; chromosome count; coalescent; Bayes Factors; Systematics and phylogenetics; Systematik och fylogeni; systematisk botanik; Systematic Botany;

   Abstract : This thesis focuses on phylogenetic relationships among some of the major lineages in Silene subgenus Behenantha (Caryophyllaceae) using DNA sequences from multiple, potentially unlinked gene regions from a large taxonomic and geographic sample. Both traditional phylogenetic analyses and a strategy to infer species trees and gene trees in a joint approach are used. READ MORE

7. 25. Migration of Sea Turtles from Caribbean Costa Rica: Implications for Management

   Author : Sebastian Troëng; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; conservation; predation; remigration; annual survival probability; mtDNA; satellite telemetry; tagging; Costa Rica; Tortuguero; endangered; migration; Djurekologi; sea turtles;

   Abstract : Tortuguero National Park in Costa Rica hosts nesting by four species of highly migratory and endangered sea turtles (green, hawksbill, leatherback and loggerhead turtles). Sea turtle research at Tortuguero has been continuous since Dr. Archie Carr began studies in the 1950?s. READ MORE
