Odonata (dragonflies and damselflies) present an unparalleled insect model to integrate evolutionary genomics with ecology for the study of insect evolution. Key features of Odonata include their ancient phylogenetic position, extensive phenotypic and ecological diversity, several unique evolutionary innovations, ease of study in the wild and usefulness as bioindicators for freshwater ecosystems w

Extreme climatic events, such as heat waves, are predicted to increase in frequency and intensity during the next hundred years, which may accelerate shifts in hydrological regimes and submerged macrophyte composition in freshwater ecosystems. Since macrophytes are profound components of aquatic systems, predicting their response to extreme climatic events is crucial for implementation of climate

Tropical forest productivity is sustained by the cycling of nutrients through decomposing organic matter. Arbuscular mycorrhizal (AM) fungi play a key role in the nutrition of tropical trees, yet there has been little experimental investigation into the role of AM fungi in nutrient cycling via decomposing organic material in tropical forests. We evaluated the responses of AM fungi in a long-term l

As blooms of cyanobacteria expand and intensify in freshwater systems globally, there is increasing interest in their ecological effects. In addition to being public health hazards, cyanobacteria have long been considered a poor quality food for key zooplankton grazers that link phytoplankton to higher trophic levels. While past laboratory studies have found negative effects of nutritional constra

Local adaptation to rare habitats is difficult due to gene flow, but can occur if the habitat has higher productivity. Differences in offspring phenotypes have attracted little attention in this context. We model a scenario where the rarer habitat improves offspring's later competitive ability – a carryover effect that operates on top of local adaptation to one or the other habitat type. Assuming

Peatlands and forests cover large areas of the boreal biome and are critical for global climate regulation. They also regulate regional climate through heat and water vapour exchange with the atmosphere. Understanding how land-atmosphere interactions in peatlands differ from forests may therefore be crucial for modelling boreal climate system dynamics and for assessing climate benefits of peatland

Lake restoration practices based on reducing fish predation and promoting the dominance of large-bodied Daphnia grazers (i.e., biomanipulation) have been the focus of much debate due to inconsistent success in suppressing harmful cyanobacterial blooms. While most studies have explored effects of large-bodied Daphnia on cyanobacterial growth at the community level and/or on few dominant species, pr

Agricultural fertilization significantly affects arbuscular mycorrhizal fungal (AMF) community composition. However, the functional implications of community shifts are unknown, limiting understanding of the role of AMF in agriculture. We assessed AMF community composition at four sites managed under the same nitrogen (N) and phosphorus (P) fertilizer regimes for 55 yr. We also established a glass

This thesis covers issues related to financing in mergers and acquisitions. It studies the relationship between firms’ financing conditions and firms’ decisions to either buy or sell assets.The first paper, "Cross-border mergers and acquisitions with financially constrained owners", studies the effects of costly external financing in international asset sales. We propose a cross-border merger mode

Scholars of international law and international relations largely agree that global governance today, and global environmental governance in particular, is marked by institutional complexity. Environmental policy fields are, to varying degrees, governed by a plurality of institutions with different levels of legalization, membership, and jurisdictional scope, and with different degrees of coherenc

The idea that noncrop habitat enhances pest control and represents a win–win opportunity to conserve biodiversity and bolster yields has emerged as an agroecological paradigm. However, while noncrop habitat in landscapes surrounding farms sometimes benefits pest predators, natural enemy responses remain heterogeneous across studies and effects on pests are inconclusive. The observed heterogeneity

The agriculture sector can contribute to climate change mitigation by reducing its own greenhouse gas (GHG) emissions, sequestering carbon in vegetation and soils, and providing biomass to substitute for fossil fuels and other GHG-intensive products. The sector also needs to address water, soil, and biodiversity impacts caused by historic and current practices. Emerging EU policies create incentiv

While wild pollinators play a key role in global food production, their assessment is currently missing from the most commonly used environmental impact assessment method, Life Cycle Assessment (LCA). This is mainly due to constraints in data availability and compatibility with LCA inventories. To target this gap, relative pollinator abundance estimates were obtained with the use of a Delphi asses

Is it truly the "end" of public space? This handbook presents evidence that the answer is "no". In cities in different parts of the world, people still use public space to pursue activities of their choice.The book is divided into seven sections. The first section presents three emerging types of public space. Each of the subsequent five sections focuses on a type of activity: recreation, commerce

The purpose of this thesis is to investigate how the characteristics of the employment conditions for a professional athlete appears, relative to the conclusion of the contract, the ongoing employment and the termination of the contract. It has been shown that sport has its own organization, with a high degree of autonomy, with its own legal framework. This does not, however, hinder labor regulati

Makten att styra Sverige tillkommer statsråden, vilka utgör regeringen. Regeringsmakten begränsas genom lagbundenhet och funktionsfördelning. Riksdagens funktion är bland annat att kontrollera statsrådens arbete. Statsråden har ett såväl politiskt som rättsligt ansvar inför riksdagen. Uppsatsen utreder ifall regelverket för statsråds rättsliga ansvar för handlande i tjänsteutövningen är tillfredssThe power to govern Sweden belongs to the ministers, who form the government. The governmental powers are limited by law and by distribution of functions. One of the functions of the parliament is to monitor the work of the ministers. The ministers have both a political and a legal responsibility before the parliament. This essay examines whether the legal framework regarding the responsibility th

Socialtjänsten har ett särskilt ansvar för barn. Detta åtagande innebär bland annat att staten har en skyldighet att vårda barn vars hälsa eller utveckling riskerar att skadas. I första hand ska vården, liksom stöd och andra insatser som socialtjänsten ansvarar för och tillhandahåller, beredas på frivillig väg. Det kan dock uppstå situationer då det är nödvändigt att ingripa med tvång från samhällThe social service has a special responsibility for children. This commitment means, among other things, that the state has an obligation to care for children whose health or development is at risk of injury. To the extent possible, the care shall, as in the case of other activities carried out by the social services, be provided on a voluntary basis. However, it may occur situations when it is ne

Health care access has always preoccupied human societies. Today citizens can travel abroad to obtain timely and/or affordable health care. Cross-border healthcare regulation has been established in the European Union to facilitate patient mobility and safety. Outside the EU medical travel however remains unregulated. This study thereby seeks to compare EU-regional and global patient mobility, and
