Agricultural production systems are under pressure to contribute to climate mitigation, biodiversity conservation, and resilient food production. This calls for multifunctional strategies, potentially including integrated biomass production in intensively farmed landscapes to generate renewable energy and positive environmental impacts as co-benefits. Despite this, broader implications of large-sc
Popular Abstract in Swedish Energiförsörjning är essentiellt för alla samhällen världen över, men jordens resurser är inte obegränsade. Växter utgör en stor källa av förnyelsebara råvaror som skulle kunna användas för att ersätta en del fossila energikällor och material. I växters cellväggar finns olika typer socker som sitter ihop i kedjor av så kallade polysackarider. Cellulosa är den mest kändaβ-Mannoside hydrolases are enzymes that are involved in conversion of the major soft-wood hemicellulose O-acetyl-galactoglucomannan, an important renewable biomass resource. They belong to clan A of glycoside hydrolases and share a common (β/α)8-TIM barrel fold. For their catalysis, they use a two-step retaining double displacement mechanism, and may in addition to hydrolysis also perform transgly
CONTEXT: Uptake of organic farming falls short of stated sustainability targets, particularly in highly productive regions where adoption could mitigate environmental impacts of intensive farming. Several hypotheses have been advanced to explain the constraints on adoption, but these have not been assessed within an integrative, interdisciplinary framework.OBJECTIVE: The objective was to develop a
Endotoxin exposure is associated with wheeze and asthma morbidity, while early life exposure may reduce risk of allergy and asthma. Unfortunately, it is difficult to compare endotoxin results from different laboratories and environments. We undertook this study to determine if lipopolysaccharide ( LPS) extraction efficiency could account for differences among laboratories. We generated and collect
One of the most pressing present day health concern is the constantly growing increase of diabetes and the metabolic syndrome. In fact the WHO estimates that as much as 300 million individuals could suffer from diabetes by 2025. While genetic factors do contribute to these issues the more common cause is modern day environmental factors like diets rich in fat or highly processed food, low levels o
Isoprene is a highly reactive volatile organic compound emitted by vegetation, known to be a precursor of secondary organic aerosols and to enhance tropospheric ozone formation under polluted conditions. Isoprene emissions respond strongly to changes in meteorological parameters such as temperature and solar radiation. In addition, the increasing CO2 concentration has a dual effect, as it causes b
Research in global change ecology relies heavily on global climatic grids derived from estimates of air temperature in open areas at around 2 m above the ground. These climatic grids do not reflect conditions below vegetation canopies and near the ground surface, where critical ecosystem functions occur and most terrestrial species reside. Here, we provide global maps of soil temperature and biocl
Boreal forests have a large impact on the global greenhouse gas balance and their soils constitute an important carbon (C) reservoir. Mature boreal forests are typically a net CO2 sink, but there are also examples of boreal forests that are persistent CO2 sources. The reasons remain often unknown, presumably due to a lack of understanding of how biotic and abiotic drivers interact to determine the
The mechanical behaviour of wood was studied from a micro up to a macro level. Wood is a cellular material possessing a high degree of anisotropy. Like other cellular solids, it often exhibits a highly nonlinear stress–strain behaviour. In the present study the mechanical properties of the cellular structure of wood are characterized and modelled, the irregular cell shape, the anisotropic layered
Horisonter med subfossila stubbar och rötter av tall (Pinus sylvestris) är vanliga i stratigra-fier från torvmarker i norra Europa. Dessa är tydliga indikationer på att det under holocen funnits perioder med tillräckligt gynnsamma förhållanden för tallar att växa på mossar. Tall kan endast växa på mossar när ytan är tillräckligt torr, och därför är rester av tallar på mossar goda indikationer på eHorizons rich in subfossil stumps and roots of Scots pine (Pinus sylvestris) are frequently found in stratigraphies of northern European peatlands, providing clear evidence of Holocene periods with favourable conditions for bog-pine growth. The pines could only grow when bog-surface wetness was sufficiently low, and the presence of their remains is therefore a good indicator of past climatic condi
Vår avsikt med uppsatsen är att beskriva och analysera medias larmrapporters inverkan på livsmedelsprodukternas nuvarande situation och framtid. Vi undersöker varför vissa företag lyckas bättre respektive misslyckas med sin krishantering utifrån hur de bemöter larmen.Vi har utgått från teorin Crisis Management, där vi har funnit en applicerbar modell på vårt syfte, Crisis Response System, som komp
Increasing aridity is one major consequence of ongoing global climate change and is expected to cause widespread changes in key ecosystem attributes, functions, and dynamics. This is especially the case in naturally vulnerable ecosystems, such as drylands. While we have an overall understanding of past aridity trends, the linkage between temporal dynamics in aridity and dryland ecosystem responses
