1. Genetic diversity and differentiation in natural and managed stands of Norway spruce (Picea abies)
Sammanfattning : Being one of Sweden’s most important tree species, both as a keystone species and for the forest industry, it is important that we keep our stands of Norway spruce (Picea abies (L.) Karst.) as healthy as possible. LÄS MER
2. Is genetic diversity more important for terpene emissions than latitudinal adaptation? : Using genetically identical trees to better understand emission fluctuations across a European gradient
Sammanfattning : Biogenic volatile organic compounds (BVOCs) are trace gases other than CO2 and CH4 produced and emitted by the vegetation. The group consists of thousands of compounds in various shapes and sizes and with short atmospheric lifetimes. Some of the most common BVOC groups are called isoprene, monoterpenes and sesquiterpenes. LÄS MER
3. Geographic differentiation and population history in Silene dioica and S. hifacensis: variation in chloroplast DNA and allozymes
Sammanfattning : In this thesis I used allozymes and PCR-RFLP analysis of chloroplast DNA (cpDNA) to investigate geographic differentiation within the widespread Silene dioica (L.) Clairv. (Caryophyllaceae) and the narrowly-distributed S. hifacensis Rouy ex Willk. LÄS MER
4. Behavioural differences and genetic relationships between four captive populations of red junglefowl (Gallus gallus) : possible implications for conservation
Sammanfattning : 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. LÄS MER
5. Behavioural aspects of conservation breeding : Red junglefowl (Gallus gallus) as a case study
Sammanfattning : Ett stort antal utrotningshotade djurarter ingår idag i bevarandeprogram världen över. Små populationer hålls då i skyddade miljöer, exempelvis i djurparker, och i många fall är målet att återintroducera djur till naturen. LÄS MER
