  2. 1. Fungal disease dynamics, genetic variation and biodiversity-yield relationships : — a study along a gradient of coffee management in southwestern Ethiopia

    Author : Beyene Zewdie Hailu; Kristoffer Hylander; Ayco J.M Tack; Jacques Avelino; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Armillaria root rot; biodiversity; biodiversity-yield trade-offs; coffee; Coffea arabica; coffee berry disease; coffee leaf rust; coffee wilt disease; coffee yield; genetic composition; genetic diversity; hyperparasite; management intensity gradient; southwestern Ethiopia; Plant Ecology; växtekologi;

    Abstract : Intensification of agricultural systems is a major threat to the associated biodiversity and could also affect the dynamics of pests and pathogens. One such system that is currently under an intensification trajectory is the production of Arabica coffee. READ MORE

  4. 2. Behavioural differences and genetic relationships between four captive populations of red junglefowl (Gallus gallus) : possible implications for conservation

    Author : Jennie Håkansson; Linköpings universitet; []
    Keywords : Red junglefowl; behavioural differences; genetic relationships; captive populations; NATURAL SCIENCES; NATURVETENSKAP;

    Abstract : Conservation of species is to a large extent carried out by zoos where animals are kept in small populations under protected conditions. The ultimate goal of such ex situ conservation programs is to eventually reintroduce the animals into natural habitats to provide support for the survival of the species. READ MORE

  5. 3. Genetic studies in rheumatoid arthritis : familial studies and analysis of relationships to atherothrombotic comorbidity

    Author : Lisbeth Ärlestig; Solbritt Rantapää Dahlqvist; Dan Holmberg; Åsa Torinsson Naluai; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Rheumatoid arthritis; genetics; familial studies; ACPA and cardiovascular co-morbidity; reumatologi; rheumatology; genetik; Genetics; cardiovascular disease; hjärt- och kärlforskning;

    Abstract : Background. Rheumatoid arthritis (RA) is an autoimmune disease mainly affecting the joints but has also extra articular manifestations and an increased cardiovascular (CV) co-morbidity. Rheumatoid factor (RF) and antibodies against citrullinated proteins/peptides (ACPA) are diagnostically important and are related to a more severe disease. READ MORE

  6. 4. Alcohol Consumption among Adolescents : Psychosocial and Genetic influences

    Author : Erika Comasco; Kent W. Nilsson; Lars Oreland; Rainer Spanagel; Uppsala universitet; []
    Keywords : adolescents; alcohol; biomarkers; depression; drinking motives; FAEE; gene environment interaction; interview; OPRM1; PER2; PEth; questionnaire; sleep; Neuroscience; Neurovetenskap;

    Abstract : The present thesis is based on four studies focusing on alcohol consumption among Swedish adolescents, and therewith related psychosocial and genetic factors. One main objective was to study the reasons for drinking alcohol among different population - representative samples of adolescents in order to identify motives for drinking. READ MORE

  7. 5. Sex Chromosome Evolution in a Hermaphrodite : Genetic and phenotypic relationships between sex roles

    Author : Anna Nordén; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Sex chromosome evolution; Hermaphrodite; Inter-sexual genetic correlation; Quantitative genetics; Macrostomum lignano; Experimental evolution; Sexual conflict;

    Abstract : Sex chromosome evolution in a hermaphrodite ancestor starts with the establishment of a sex-determining region (SDR). Over time, sex-specific genes, and/or sexually antagonistic alleles will become linked to the SDR. READ MORE
