Bakgrund: Demenssjukdom är en vanlig orsak till funktionsnedsättningar främst bland äldre och påverkar både kognitiva och fysiska förmågor samt leder till mindre självständighet och delaktighet. Det finns flera arbetsterapeutiska interventioner för personer med demens, men kartläggningar och utvärderingar av interventioner som har vetenskapligt stöd behövs. Syfte: Att kartlägga arbetsterapeutiska Background: Dementia is a common cause for disabilities, mainly affecting older adults cognitively and physically, making them more dependent and diminishing their participation in activities. There are several occupational therapy interventions for people with dementia, however summaries and evaluations of scientific evidence are needed. Aim: To summarize occupational therapy interventions that
Hybridization may generate novel trait values and combinations, enabling hybrid lineages to exploit new niches. While phenotypic differences among hybrids and parents are well characterized, it is less well understood if behaviors are likely to be intermediate, mosaic, or transgressive, outside the parental ranges of values. To address how behavioral traits evolve in hybrid lineages, we use the ho
Uttrar och viltkameror: Att avslöja artens ekologi Uttern (Lutra lutra) är ett semiakvatiskt mårddjur som främst äter fisk. Efter nära utrotning på 1900-talet är den svenska populationen nu på uppgång, med omkring 4000 reproducerande individer. Uttern är en skygg art, och mycket är därför oklart kring dess ekologi. För att säkra artens framtid i Sverige behövs mer kunskap, särskilt lokalt. Denna The otter (Lutra lutra) is a cryptic, semi-aquatic mustelid, with several uncertainties regarding its ecology and reproductive success in Sweden. To ensure future conservation, distribution and population estimates are needed and the ecological knowledge gaps must be filled in. This study aimed to examine three ecological factors possibly related to the occurrence and distribution of the Scanian o
Moth Wars: The Honeybee Strikes Back In an ecosystem far, far away, there is a plant, a moth and a bee. Deep in the mountains of Sierra Nevada, the plant and the moth are living happily together. But then, an invading foe arrives, the invasive honeybee, that with the help of dark, mystic powers (humans) conquers all land they touch. Our little duo of plant and moth would not be the first to peris
Livsmiljömodell för mindre hackspett (Dryobates minor) En livsmiljömodell är ett verktyg som har börjat bli alltmer vanligt i bevarandearbeten. För att bygga en livsmiljömodell behövs ekologisk kunskap om arten i fråga. En väl fungerande modell ger information om var arten har mest lämpliga livsmiljöer och var vi kan förvänta oss att hitta den. Ofta görs livsmiljömodeller för arter som kräver bevAcross Europe, breeding bird species are decreasing in several types of habitats. Deciduous forest specialist birds are facing a loss of habitat due to the forest management that removes important key components in the forest, e.g. dead wood. Already in Sweden three woodpecker species that are deciduous forest specialist have decreased in population: one has become locally extinct (middle spotted
This study aims to examine whether sustainable firms are more sensitive to economic hardship such as an economic crisis, high inflation and low GDP-growth than companies with less focus on sustainability. The research is based on publicly available taxonomy scores of twenty-three of largest publicly traded stocks in Sweden between 2003-2023. The results from three regressions, based on the same mo
Vad påverkar gäddans storlek och antal på den svenska östkusten och hur bör arten förvaltas? Gädda Esox Lucius är en högt eftertraktad fisk inom fritidsfisket, och som predator i toppen av näringskedjan har arten en viktig roll i ekosystemen. I östersjön förekommer gäddan i två olika populationer som lever i grunda havsvikar. Den ena populationen leker i vikarna, medan den andra migrerar till sötThe northern pike Esox Lucius is a highly sought-after resource targeted by recreational anglers but now declining. In the Baltic Sea the species consist of two sympatric populations residing in the shallow coves. However, with difficulties to assess the relatively stationary species, this project aimed to bring to light important factors of pike habitats using a new method of electrical fishing b
The European pond turtle (Emys orbicularis) is a redlisted freshwater turtle species and a protected species in France. It is relying strongly on immerged habitats for most of its active life cycle, but depends also on land habitats for egg deposition. As most wetland species, it is undergoing severe pressures due to the reduction and degradation of its habitats. In the Mediterranean, rises in sal
Stormwater pollution is known to alter river water quality, but its impacts on aquatic biodiversity remain poorly understood. This study investigates the effects of stormwater runoff on water quality and benthic macroinvertebrate communities in the Rönne å river, southern Sweden. A field-based study was conducted in rural and urban river sections, comparing pipe discharge sites with nearby referen

Nesting phenology in birds has been studied for decades and two different breeding strategies have been identified, income and capital breeding. The nesting behaviour and the breeding strategies of 131 females were studied from three species, the Common eider (Somateria mollissima) (n = 65), known to be a capital breeder and two species the Velvet scoter (Melanitta fusca) (n = 48) and the Red-brea
Climate change driven increases in temperature are predicted to enhance oxidative stress as well as to accelerate telomere shortening and thus ageing in ectotherms. Understanding if and how populations can adapt to environmental stressors by altering telomere dynamics and decelerating the ageing process is therefore of major concern. I approached this question by taking advantage of two naturally
Protein biosynthesis follows a hierarchical process, as genes are transcribed into mRNA, translated into a chain of amino acids, and ultimately folded into functional proteins. This implies that the protein structure is merely determined by the amino acid sequence. Yet, studies on translation efficiency indicate that codon usage, which is organism dependent, significantly impacts protein folding k
Vi alla har sett dem! Tomma hus som en gång varit trygga hem men som förvandlats till byggnader i förfall. Ofta ligger de på vackra platser, byggda med gedigna material och med lång och händelserik historia. Vi pratar såklart om alla övergivna hus som finns i Sverige. Hus som tappat sitt syfte men inte sin själ. Hus som skulle kunna ses som en resurs i den viktiga klimatomställningen och som en deWe have all seen them! Empty houses that were once safe homes but have now turned into buildings in decay. Often located in beautiful places, built with solid materials and rich in history. We are talking about the many abandoned houses found throughout Sweden. Houses that have lost their original purpose but not their soul. Houses that could be seen as a resource in the important climate transiti
The thesis examines the impact of the Trump and Biden administrations on international trade relations and agreements, specifically comparing their trade policies. It explores how their contrasting approaches—Trump's protectionist stance versus Biden's multilateral cooperation—have influenced global trade dynamics through a mixed-methods approach for analysis. The research incorporates bot
As the number of devices connected via 5G has grown tremendously over the years since its introduction, the number of unused frequency spectra has grown smaller and smaller, leading to more overlap and smaller gaps between neighbouring spectra. To ensure that all current and future devices that occupy these spectra can work together without interference or interruptions in service, care needs to b
