2. 1. Population divergence at small spatial scales : – theoretical and empirical investigations in perch

   Author : Sara Bergek; Mats Björklund; Teija Aho; Sarah Goodacre; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Perca fluviatilis L.; Perch; Small scale genetic differentiation; Morphometrics; Isolation by distance; Dispersal; Gene flow; Microsatellites; Spatiotemporal stability; Barriers; Biology; Biologi; Terrestrial; freshwater and marine ecology; Terrestrisk; limnisk och marin ekologi; Animal Ecology; zooekologi;

   Abstract : Genetically structured populations arise when gene flow between groups of individuals is hindered by geographical, behavioural or temporal barriers. The identification of such groups is important for understanding evolution and has large implications for conservation concern. READ MORE

4. 2. Global bifurcations and chaotic dynamics in physical applications

   Author : Martín G. Zimmermann; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum chemistry; Global bifurcations; Šil´nikov phenomenon; degenerate homoclinic orbit; onset of spatiotemporal chaos; heteroclinic cycles; orientation- and inclination-flip bifurcations; Kvantkemi; Quantum chemistry; Kvantkemi; Quantum Chemistry; kvantkemi;

   Abstract : The aim of this work has been to analyse global bifurcations arising in a laser with injectedsignal and in a catalytic reaction on a surface of Pt, from the point of view of dynamicalsystems theory.The 3-dimensional ordinary differential equation which models the laser was found to contain a homoclinic orbit to a saddle-focus equilibrium, what corresponds to the Šil´nikov phenomenon.

5. 3. Using Light to Regulate the Activity of RET Kinase: Design, synthesis and evaluation of photoswitchable DFG-out RET kinase inhibitors

   Author : Yongjin Xu; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; RET kinase; kinase inhibitor; DFG-out; photoparmacology; azoheteroarene; Buchwald-Hartwig coupling; quinoline; 7-azaindole;

   Abstract : Protein kinases are essential for signal transduction and regulate most cellular processes, such as metabolism, membrane transport, motility, and cell cycle. Although they play a critical role in cells and have a strong association with diseases, details of their physiologic and pathologic mechanisms remain at least partially unclear, especially the spatiotemporal dynamics of the signalling.

6. 4. Entering the dynamic risk space : Assessing planetary boundary interactions through process-based quantifications

   Author : Arne Tobian; Johan Rockström; Sarah Cornell; Ingo Fetzer; Dieter Gerten; Martin Volk; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Planetary boundaries; climate change; land-use change; Earth system interactions; ecosystem modeling; green water; vetenskap om hållbar utveckling; Sustainability Science;

   Abstract : The planetary boundaries framework is an effort to define a safe operating space for humanity. Its rationale is that sustainable development needs to be achieved in ways that safeguard the stability of the Earth system on which human prosperity relies. READ MORE

7. 5. Fishing the gene pool : Genetic structure, admixture and behavioural complexity in fisheries management

   Author : Kim H. Berndt; Enhet akvatisk ekologi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fisheries management; Fishery stock; Stock discrimination; Genetic structure; Genetic admixture; Admixture zone; Stock substructure; Phenotypic divergence; Gadus morhua; Salmo trutta;

   Abstract : Prudent management of marine fish resources relies on separation and management of biologically meaningful groups of conspecifics, termed fishery stocks, often depicted as self-sustaining, spatiotemporally separated and demographically independent entities. Such stock discrimination has however proven challenging. READ MORE
