16. Fragmented landscapes : Assessment and communication of landscape connectivity in human-dominated landscapes
Sammanfattning : This licentiate thesis summarizes the first half of my PhD on the theme of management of fragmented landscapes. The thesis applies – and reflects on the use of – network analysis of connectivity in relation to landscape planning. LÄS MER
17. Traditional use of wildlife in modern society : public attitudes and hunters' motivations
Sammanfattning : Populations of many large mammals and birds are increasing in many parts of Europe and North America. At the same time, the number of hunters is generally decreasing and an increasing proportion of people live in urban areas. LÄS MER
18. Diversity, dispersal, and interactions among diving beetles and mosquitoes in Swedish wetlands
Sammanfattning : In this thesis, I explore why biodiversity, as exemplified by diving beetle and mosquito faunas, differs between wetlands, and what environmental factors that affect and control diversity in different types of wetlands and landscapes. The study organisms, diving beetles (Dytiscidae) and mosquitoes (Culicidae), are abundant and species-rich groups in many types of wetlands. LÄS MER
19. A Deep Dive into Sediments : Exploring approaches to assess environmental risks and achieving environmental goals in management of contaminated sediments in Sweden
Sammanfattning : Contaminated sediments are common, especially near urban and industrialized areas, and they can have negative ecological effects. In three studies, I explore the challenges for environmental management of contaminated sediments, focusing on environmental risk assessment (ERA) in Sweden. LÄS MER
20. Gene expression and antibiotic resistance in Escherichia coli from Swedish inland waters
Sammanfattning : Extensive use of antibiotics both from human-medicine and veterinary sources are believed to provide selective pressure on bacteria that leads to an increase in antibiotic resistance in environmental waters. Contamination of antibiotic resistant microbes will raise human health risks. LÄS MER
