Urbanization is gaining force globally, which challenges biodiversity, and it has recently also emerged as an agent of evolutionary change. Seasonal phenology and life cycle regulation are essential processes that urbanization is likely to alter through both the urban heat island effect (UHI) and artificial light at night (ALAN). However, how UHI and ALAN affect the evolution of seasonal adaptatio

We present the results of the Swedish Bird Survey, run by the Department of Biology, Lund University, as a part of the National Monitoring Programme of the Swedish Environmental Protection Agency. The results for 2019 include data from: 575 winter point counts in 2018/2019 (44th winter), of which 285 were carried out during the Christmas/New Year count, 210 summer point count routes (45th year) an

Over the last decades, there has been a rapid increase of the number of climate change initiatives outside the UNFCCC. In research this is referred to as ‘institutional fragmentation’, and it encompasses a wide range of public, private and hybrid initiatives, at various levels of governance. This development is extensively discussed in the IPCC Fifth Assessment Report AR5. Chapters 13-16 of the Wo

Permanent ponds are valuable freshwater systems and biodiversity hotspots. They provide diverse ecosystem services (ESs), including water quality improvement and supply, food provisioning, and biodiversity support, despite significant pressure from multiple anthropogenic stressors and the impacts of ongoing global change. However, ponds are largely overlooked in management plans and legislation, a

Declines in European bird populations are reported for decades but the direct effect of major anthropogenic pressures on such declines remains unquantified. Causal relationships between pressures and bird population responses are difficult to identify as pressures interact at different spatial scales and responses vary among species. Here, we uncover direct relationships between population time-se

Species’ range shifts and local extinctions caused by climate change lead to community composition changes. At large spatial scales, ecological barriers, such as biome boundaries, coastlines, and elevation, can influence a community's ability to shift in response to climate change. Yet, ecological barriers are rarely considered in climate change studies, potentially hindering predictions of biodiv

Climate change has been associated with both latitudinal and elevational shifts in species’ ranges. The extent, however, to which climate change has driven recent range shifts alongside other putative drivers remains uncertain. Here, we use the changing distributions of 378 European breeding bird species over 30 years to explore the putative drivers of recent range dynamics, considering the effect

BACKGROUND: Analyses of clinical outcomes following radiotherapy (RT) have advanced our understanding of fundamental radiobiological characteristics in head and neck squamous cell carcinoma (HNSCC). Low fractionation sensitivity appears to be a common feature, as well as susceptibility to changes in overall treatment time (OTT). Large tumors should be harder to cure if a successful RT requires the

Petrochemical producers both rely upon and generate some of the most problematic substances in the current age of socioecological crisis: fossil fuels and plastics. With mounting calls to cap fossil fuel extraction as well as plastics production, the industry appears to be caught between a rock and a hard place. Nonetheless, betting on continuously increasing global plastic demand, petrochemical p

The upcoming implementation of the ReFuelEU Aviation Initiative presents both challenges and opportunities for the European aviation sector. Starting January 2025, the EU’s aviation fuel mix must include at least 2% Sustainable Aviation Fuel (SAF), leading to higher operating costs for airlines due to SAF’s higher price than fossil kerosene. Additionally, the entire fuel supply chain will need to

Fresh water resources face risks due to urbanisation, economic development, and climate change (CC). Many small and medium-sized cities (SMCs) are particularly vulnerable to these risks due to the lower resource capacity required to mitigate them. Nature-based Solutions (NbS) for water resource management (WRM) are promising to tackle these issues in urban areas while providing extra benefits to s

In this thesis, a fault detection and diagnosis system is developed for the Crazyflie 2.1 unmanned aerial vehicle. Different types of faults are investigated and suitable methods and tests are implemented. The system is mainly developed for the lighthouse positioning, but the tests and methods are generic and suitable for other parts of the Crazyflie eco-system. For the faults investigated, differ

In this thesis work, the design challenges of building a robust Battery Management System with the existing solutions are discussed highlighting the communication within the battery pack. The initial plan of this master thesis work was to investigate wireless BMS technologies and to implement a wireless BMS, as a demo prototype for three segments with wired BMS for a full 7.2 kWh battery pack. Aft

This master thesis investigates the synthesis, structural characterization and electrochemical performance of copper(II) oxide (CuO) and cobalt-doped CuO nanofibers as electrocatalysts for the electrochemical nitrate reduction reaction (NO3-RR). The overarching aim is to assess their potential for sustainable ammonia production under ambient conditions. A series of exploratory synthesis trials rev

There are fungi whose delectability and even whose shift from toxicity to edibility depends on preparation in the kitchen. The milkcaps Lactarius rufus and Lactarius trivialis and the false morel Gyromitra esculenta are three such mushrooms. The former two will burn your tongue if nibbled raw, and may bring on stomach-ache if not boiled prior to further cooking. The latter could kill you if it is

Bioenergy is the largest energy source in the Swedish energy system, where it consists mainly of domestic forest-based biomass in the form of residues and by-products. Today, there is a general discussion about the need for changes in national forest management policies and new European Union (EU) directives and regulations for forestry and bioenergy to better fulfil biodiversity and climate targe
