Land degradation and soil erosion are considered one of the main threats to ecosystem services and functions, soil stability and activity, plant community structure and biodiversity, and overall life on Earth. Soil erosion is a problem occurring all over Iceland, with an immediate urgency on the Icelandic highlands and rangelands. Currently, over 40% of the country is eroded, steadily causing loss

Climate change is affecting all regions of the globe, causing a shift of temperature distributions. As species try to track their optimal thermal conditions, they are also potentially met with new photic environments. Photoperiod is the main cue for synchronizing migratory birds' circannual rhythms, affecting both their physiology and migration. Thus, their ability to incorporate and adjust to

The decision of when to exchange habitats represents a significant moment for organisms that utilize migration as a strategy to access growth and feeding opportunities surpassing those available in their natal habitat. For juvenile anadromous salmonids, the initial transition from freshwater to the marine environment marks a critical point in the life cycle characterized by high mortality with mig

The central area of Stenshuvud national park in southern Sweden was surveyed regarding the lichen species composition and distribution. Similar qualitative investigations of the area have been carried out in the years 1934 and 1987, although this survey further included a quantitative survey of relative frequency per species to enable more accurate monitoring in the future. Together, the three s

Naturen har länge varit en källa till inspiration inom läkemedelsutvecklingen, eftersom växter ofta innehåller strukturellt komplexa och biologiskt aktiva molekyler. Ett exempel på en sådan växt är Ålandsroten, som har upptäckts genom sin betydelse i läkemedelskonsten. I den gula lilla blomman finns Isoalantolactone, med lovande egenskaper mot cancer, bakterieinfektioner, virus och inflammationer.For centuries, nature has served as a source of inspiration in drug discovery, offering structurally complex and biologically potent compounds. This study focuses on Isoalantolactone, (IAL), a sesquiterpene lactone found in Inula Helenium. The lactone examplifies the promise of natural products in drug discovery, by demonstrating significant bioactive properties such as anti-cancer, anti-bacterial

This study investigates the presence of excess comovement in the Swedish stock market by analyzing index events from the OMX Stockholm Benchmark Index. Using univariate regressions with OLS estimation, changes in stock return behavior before and after an index event are examined, while controlling for momentum effects and pre-trading influences. T-tests are conducted to determine the statistical s

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

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

Denna studie undersöker sambandet mellan variablerna arbetskrav, organisationskultur och socialt stöd, på utfallsmåttet, benägenhet till sjuknärvaro. Med avsikt att upptäcka viktiga insikter inriktade sig studien på följande delar: kvantitativa krav, känslomässiga krav, socialt stöd från överordnade, socialt stöd från kollegor, tillit och trovärdighet mellan ledning och anställda samt tillit och tThis study investigates the relationship between the variables work demands, organizational culture and social support, on the outcome measure, presenteeism. With the intention of discovering important insights, the study focused on the following parts: quantitative demands, emotional demands, social support from superiors, social support from colleagues, trust and credibility between management

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
