21. The population structure of Late Pliocene and Early Pleistocene Neptunea angulata, Gastropoda and an investigation into bias in the fossil record and museum collections.
Master-uppsats, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : The fossil population structure of the gastropod Neptunea angulata from the late Pliocene and Early Pleistocene was investigated in this project in order to contribute to a wider study on the influence of predation on populations and the evolutionary history of organisms. Over time, predator-prey relationships can drive evolution in a way similar to the Red Queen Hypothesis. LÄS MER
22. Evolution av färgteckningen hos zebror : varför har zebrorna fått sina ränder och varför har olika zebraarter olika färgteckning
Kandidat-uppsats, SLU/Dept. of Animal Environment and HealthSammanfattning : Detta arbete är en litteraturstudie med syfte att gå igenom teorier bakom zebrans ränder och de eventuella anledningarna bakom arternas varierande färgteckning. Det finns många teorier som sägs vara anledningen till zebrans ränder och jag har valt ut de mest studerade teorier och de jag själv tycker är rimligast. LÄS MER
23. Analysis and Implementation of Adaptive Explicit Two-Step Methods
Master-uppsats, Lunds universitet/Matematik LTHSammanfattning : Recently a new way of constructing variable step-size multistep methods has been proposed, that parametrizes the entire domain of multistep methods. In the presented work the case of explicit two-step methods is looked at, analyzed and related to the already known theory of multistep methods. LÄS MER
24. Temporal correlation between the acoustic activity of harbor porpoise and the movement activity of their prey species at Kullaberg, Sweden
Kandidat-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : The harbor porpoise is considered a threatened species in Swedish waters. A full understanding of its ecology and relationship to other species is important when designing effective conservation plans. LÄS MER
25. Geometrical and Evolutionary effects in a Predator-Prey System
Kandidat-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknikSammanfattning : The area of investigation is the dynamics of a predator-prey relationship. To model the relationship, an agent based model is used as a base for a simulation tool. LÄS MER
