Forest ecosystems are important actors in climate change mitigation strategies through their abilities to act as both carbon sinks and sources. The commonly used forest management strategy of clearcutting has been suggested to be paired with large greenhouse gas emissions, increasing the need for research on the climate effect from alternative management strategies. Rumperöd forest is managed thro
This study looks at the change of the Urban Heat Island (UHI) intensity in Rio Park, Madrid, which during the course of the last 20 years has in essence been retransformed from an urban highway into a flourishing green park along the Manzanares river. The deconstruction of the M-30 highway started in 2005, was completely finished in 2015, and canopy growth in the area continued during the followin
Drainage of peatlands causes changes in water table (WT), vegetation and decomposer community. As a consequence, decomposition patterns and carbon dynamics change, which is visible in altered Dissolved Organic Carbon (DOC) concentrations in ground and soil water. Additional changes in precipitation patterns towards more extreme drought and rain periods, as expected with climate change, cause furth
Growing research on ecosystem subsidies has emphasized the connection between aquatic and terrestrial ecosystems, with changes in one triggering responses in the other. In high mountain lakes, emerging aquatic insects are considered key aquatic subsidies and serve as an important nutrient resource for surrounding terrestrial ecosystem. The introduction of alien fish into these lakes, known to caus
For those who experience development-induced displacement and involuntary resettlement, they have to confront a range of adverse consequences, including the impoverishment risks, lifestyle and livelihood changes, and the precarity brought by asymmetrical power relations. Based on a case study of the Three Gorges Project (TGP), this research investigates the role of state law in shaping the identit
The coast is an ever-changing environment, and due to climate change, coastal research is becoming more challenging. To detect changes in the coastline, such as erosion, researchers need large amounts of data over long periods of time. Part of the solution could be the citizen science project CoastSnap – a global community beach monitoring program. The aim of this study was to examine factors that
When user interfaces are embedded in physical systems and cannot be accessed through conventional screen sharing, remote usability testing becomes challenging. This is increasingly relevant as products are developed for global markets, where remote evaluation is often necessary despite limited user interface access. This study investigates how alternative testing methods can be used and how they i
Due to a warming climate, tundra ecosystems are subject to shrub and treeline expansions which could lead to increased above- but decreased belowground carbon (C) stocks. An observed low soil C stock in some subarctic forests and tall shrublands has been suggested to be induced by priming of organic matter decomposition, possibly mediated by ectomycorrhizal fungi. On the other hand, the higher bel
It is impossible to conceive our modern world without plastics. Since the mass production of plastics began, humanity has produced around 8 billion tons of plastic waste, and only 9% has been recycled. Terephthalic acid polymers such as poly(ethylene terephthalate) (PET) have been massively produced over the last years thanks to their characteristics and applications. Due to their limited biodegra
China’s rapid economic development has led to a continuously increasing energy demand and the country is the world’s biggest energy user as of today. The country accounts for around 23% of the global energy production, but 70% of the Chinese energy is generated with coal power and China is the biggest emitter of CO2 in the world. The Chinese government has set a couple of goals to reduce the count
The genus Caldicellulosiruptor and especially Caldicellulosiruptor saccharolyticus are gaining attention because of their potential as biohydrogen producers from agricultural and forestry waste on an industrial scale. Genetic and in turn metabolic engineering can be used to aid in the characterization of C. saccharolyticus. Additionally, it can be used in strain improvement to overcome limiting fa
Water chemistry alterations such as acidification and eutrophication represent major threats to the running waters of the world, and Swedish waters are among the most vulnerable. In this study the small forested catchment Storskogen, part of the SWETHRO monitoring network, was analysed to examine the links between deposition, catchment hydrological properties and surface water chemistry. Storskoge
MicroRNAs are small single stranded RNA molecules containing approximately 22 nucleotides and these play an important regulatory role in gene expression. MicroRNAs are found to be involved in several diseases and knowledge about their sequences can be an important tool in the foundation of novel treatment methods against diseases. Today, these small RNA molecules are mainly analyzed with qPCR and
The undrained shear strength is a key parameter in the design process of geotechnical structures. One of the most frequently used methods to investigate this parameter is the cone penetration test (CPT). The CPT does not measure the undrained shear strength directly, but instead the resistance that a conic probe encounters as it is pushed into the ground. A calibration factor, the cone factor (Nkt
The research objective for this thesis are two problematic yet interweaving occurrences observed in earlier research on the Abu Ghraib scandal (2004) and its image material. Firstly in terms of methodology, a restricted amount of images in which three single images, “Hooded Man”, “Man on Leash” and “Piled Bodies” are overrepresented and frequently regarded as descriptive for the scandal as such. S
Hazardous substances i.e., substances of concern pose a risk to both human health and the environment. Stricter regulations and increased focus on circular economy are pushing organisations to substitute hazardous chemicals to safer alternatives. Substitution can lead to a number of benefits, for example cost reductions and competitive advantages. There has been a growing focus on substitution sin
Large and old trees provide important habitat structures and support a high diversity of species. Habitat continuity and landscape connectivity is crucial for species associated with oaks. Fragmentation, agriculture intensification and changed forest management has caused a reduction of old and large oaks, which threatens the long-term persistence of oak associated species by reducing habitat cont
