We compared the influence of the microbial community composition and the environmental conditions for the functioning - microbial growth and respiration - and trait distribution - bacterial pH tolerance - of soil microorganisms across a pH gradient. Sterilised soil microcosms, including pH 4.1, 5.2, 6.7 and 8.3, with added plant litter were inoculated with unsterilized soil in a factorial design a
This paper deals with a novel constitutive framework suitable for non-coherent interfaces, such as cracks, undergoing large deformations in a geometrically exact setting. For this type of interface, the displacement field shows a jump across the interface. Within the engineering community, so-called cohesive zone models are frequently applied in order to describe non-coherent interfaces. However,
The recent loss of pollinating insects and out-crossing plants in agricultural landscapes has raised concern for the maintenance of ecosystem services. Wild bees have been shown to benefit from garden habitats in urban and suburban areas. We investigated the effects of distance from garden habitats on wild bees and seed set of a native out-crossing plant Campanula persicifolia, in intensively mana
This project is designed as a typical consultancy work for Environmental Engineering students at the Faculty of Engineering (LTH), Lund University, Sweden. It gives students a feeling of a possible future work by being a practical training in solving a complex environmental problem involving hydrological and ecological challenges. Additionally, the project work provides training of critical thinki
Results from field experiments using a fluorescence lidar system to monitor movements of insects are reported. Measurements over a river surface were made at distances between 100 and 300 m, detecting, in particular, damselflies entering the 355 nm pulsed laser beam. The lidar system recorded the depolarized elastic backscattering and two broad bands of laser-induced fluorescence, with the separat
BACKGROUND AND OBJECTIVES: The treatment of acquired aplastic anemia (AA) is based on allogeneic bone marrow transplantation (BMT) and immunosuppressive therapy. The aim of this study was to assess the outcome of children and adults with AA treated in the last decade, and to determine whether results have improved in two sequential time periods,1991-1996 and 1997-2002. DESIGN AND METHODS: Two-thou
Microsphere-based constitutive models are a helpful tool in the modelling of materials with a microstructure composed of contributing elements directionally arranged. This is the case, for instance, for fibred soft tissues. In these models, the macroscopic mechanical behaviour is obtained from the integration of the micro-structural contribution of each component (e.g. each fibre) over the surface
With ongoing climate change, aridity is increasing worldwide, affecting biodiversity and ecosystem function in drylands. However, how the depth-profile microbial community structure and metabolic limitations change along aridity gradients are still poorly explored. Here, 16S rRNA and ITS amplicon sequencing and ecoenzymatic stoichiometry analysis were used to investigate both bacterial and fungal
The growing season start and duration, along with other temperature-related measures of importance to premium wine grapes in Napa Valley, California have changed as climate over the western United States has warmed. The growing season start has varied from year to year with a standard deviation of about 3 weeks, but over the 1958–2016 record a linear fit to the time sequence shows it advanced by m
En fulldome visning om den forskning som pågår utanför Skånes kuster producerad för Forskarfredagen.Fulldome show about the marine research of the coast of southern Sweden.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant-pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and temporal variation in floral scent emissions at
Modeling of real-world fuels and fuel mixtures in combustion engines, using computational fluid dynamics (CFD), calls for the development of compact and computationally efficient chemical kinetic mechanisms. To improve the modeling capabilities of multicomponent fuels it is necessary to transition from the single-component descriptions of fuels and move toward more complex, accurate multicomponent
In the face of escalating climate risks and impacts, the majority of people will not be able to move, will choose not to move, or may perhaps temporarily move and return to their homes. Understanding immobility in the context of climate change is thus essential to support the development of equitable and effective adaptation strategies and the resilience of people and communities that remain in at
Many plant invasions establish from only a few individuals and exhibit clonal spread, providing an opportunity to examine the genomic mechanisms that underlie the success of particularly aggressive individuals. One of the world’s most invasive species, the Japanese knotweed complex, is well suited for such investigations. Simultaneously developing ecological and genomics work in the native and int
Climate litigation has been on the rise since the beginning of the century. However, the increased use of intersectionality by plaintiffs to highlight their particular vulnerability to climate change and its impacts remains understudied. This paper provides a review of eleven intersectional climate litigation cases, along with insights from a focus group of key informants, to examine the role of i
Crises narratives surrounding the societal challenges of biodiversity loss, climate change, and human health and well-being dominate current debates in global environmental politics. These challenges are deeply interconnected and require transformative and integrated change. Marine and coastal Nature-based Solutions (blue NbS) are an opportunity to minimise harmful human impacts on these ecosystem
