By storing carbon in the biosphere, forests are mitigating climate change. Primary forests have been found to have the potential to store large amounts of carbon, but no studies on carbon storage in Swedish primary forests have been published. This study shows that Swedish primary forests store more carbon in biomass than surrounding secondary forests in the majority of cases and on average. The r
A map is a combinatorial presentation of map objects and labels providing users with sufficient and useful information. Text placement is the most time-consuming and cumbersome work in a map production process, and many methods have been proposed to automate this process. However, text placement evaluation lacks exploration, especially when artificial intelligence (AI) methods are experiencing pro
Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. By
Automatic label placement on maps has been studied for many decades. This study has addressed the problem of automatic label placement by applying the labelling library PAL for labelling static, large scale city maps which the map company T-Kartor produces. Label placement rules were acquired from an interview with a person from the company. These rules were then applied on the labelling. The aim
Extreme heat can lead to a significant increase in mortality, especially for urban citizens. Densification of urban areas can dramatically affect the local climate of the city by replacing green areas with impermeable materials and changing both radiative and turbulent fluxes. The assessment of the thermal comfort in urban areas is an important consideration for local municipalities to mitigate zo
Vegetation monitoring over time is important in a changing world due to climate change. Remote sensing, especially with the use of unmanned aerial vehicles (UAV), can be utilized to monitor vegetation at flexible scales at an accurate degree. However, the relatively new remote sensing platforms that are UAVs imply the requirement of understanding how to best monitor vegetation in an accurate way w
As global warming continues to change the global climate, extreme weather events become more common. The effects of such events vary regionally due to both natural and anthropo- genic influences. This study identifies the main mechanisms causing coastal erosion in Äng- elholm and evaluates the adaptation measures implemented by the municipality. A case study of Vejbystrand, a sandy beach in the mu
Sustainable forest management requires accurate and up-to-date baseline data regarding forest structural parameters and the definition of forest stand units. A crucial component in stand characterization is the identification of tree species and to correctly define the stand boundaries. The most common procedure used for this is land cover classification using remote sensing data. However, when cl
Glacier advances in the Écrins massif (French Alps) during the Late Glacial and the Early Holocene are poorly constrained. Based on field observations, a high-resolution digital elevation model and an orthophoto, glacial landforms in the upper Drac Blanc catchment were mapped. Thanks to 42 new 10Be exposure ages, the timing of the stabilisation of selected moraines was constrained. The application
Due to its high vulnerability, permafrost is one of the key features studied in the field of climate change impacts. Permafrost is widespread in the Arctic region. The majority of the area underlain by permafrost is however difficult to access for in-situ monitoring and it is difficult to get an overview of the current state of permafrost in many areas. Permafrost modeling provides a solution whi
In the past decades, increased organic carbon concentrations have been reported from freshwaters across the Northern Hemisphere. However, there is little knowledge regarding whether or not these changes are linked to increasing concentrations of organic nitrogen. This poor understanding of nitrogen biogeochemistry is a problem in face of the potential eutrophication effects of nitrogen in receivin
The aim of this study was to model the impacts of climate change on potential geographical distribution of Prunus africana in the Eastern Arc Mountains of Tanzania. Maximum Entropy modelling was used to construct species distribution maps for P. africana to determine relative contribution, and effects of climate change on the potential geographical distribution of P. africana based on climatic sce
The Greenland Ice sheet (GIS) is the second largest ice sheet on Earth and thus stores a large amount of Earths freshwater. Because of climate change and the Arctic amplification, GIS is experiencing changes and increased melt rates. The total mass budget determines the amount of sea level rise caused by input from freshwater from the GIS. Surface mass balance (SMB) plus the dynamic mass losses fr
A microscopic method was developed to detect pressure thresholds for gas outflow and solution impregnation during vacuum impregnation of plant materials. Raw materials with different porosities (apple and spinach) were impregnated with an isotonic sucrose solution at a minimum pressure of 150 mbar. An automatic vacuum controller system (AVCS) was used to control the pressure during vacuum impregna
BackgroundImprovement of traditional methods for dietary assessment is necessary, especially in rural areas where it is more difficult to succeed with self-reporting methods. This study presents and validates a method for improving accuracy when measuring food and nutrient intake of individuals in rural areas. It is called the “Food photography 24-h recall method” (FP 24-hR) and is a modified
Chymosin-induced gelation properties of the milk of around 400 Swedish Red dairy cows was investigated with the aim of identifying genetic protein variants that influence chymosin-induced gelation for optimisation of cheese milk through breeding practices. The variation in chymosin-induced gelation properties was shown to be large in the milk of Swedish Red and there was a high frequency of cows p
