Arthropod predators and detritivores are among the first colonisers on land surfaces undergoing primary succession. In the absence of higher plants and herbivores, they may either have an allochthonous food source (i.e. of geographically distant origin) or local food source that is sustained by e.g. microorganisms. By studying spiders and collembolans on sites along chronosequences on recently eme
Specialist plant species in calcareous sandy grasslands are threatened by acidification and high nutrient levels in the topsoil. We investigated whether topsoil removal and soil perturbation in degraded sandy grasslands could lead to establishment of specialist species belonging to the threatened xeric sand calcareous grassland habitat. Restoration actions performed in 2006 resulted in increased s
This paper provides a framework to understand the source of the economic value of soil biodiversity and soil ecosystem services and maps out the pathways of such values. We clarify the link between components of the economic value of soil biodiversity and their associated services of particular relevance to soils. We contend that soil biodiversity and associated ecosystem services give rise to two
The influence of soil physicochemical properties on microbial communities can be large, especially in developing soils of glacier forefield chronosequences. However, small-scale expositional differences in bare soils and their impacts on soil microbial communities have so far been largely neglected. Here we studied the changes of microbial communities in three deglaciated unvegetated sites along a
Soils are extremely rich in biodiversity, and soil organisms play pivotal roles in supporting terrestrial life, but the role that individual plants and plant communities play in influencing the diversity and functioning of soil food webs remains highly debated. Plants, as primary producers and providers of resources to the soil food web, are of vital importance for the composition, structure, and
While the effect of disturbance on overall abundance and community composition of arbuscular mycorrhizal (AM) fungi has been researched in agricultural fields, less is known about the impact in semi-natural grasslands. We sampled two AM plant species, Festuca brevipila and Plantago lanceolata, from an ongoing grassland restoration experiment that contained replicated plowed and control plots. The
Organic material of different origin is commonly used as fertiliser in agricultural practices. Clover and wheat straw are here used to determine the importance of organic amendment for population development of fungal feeding collembolans. Two fungal species, Alternaria infectoria and Mucor hiemalis, were inoculated in three growth substrates, clover amended soil, straw amended soil and non-amende
This thesis provides a critical overview of the development of corporate governance practices in the EC. It seeks to determine if the Community should follow the US response to corporate governance fallouts or instead promote its own practices, taking into consideration the legal and economic backgrounds of the Member States. The analysis is supported with economic data, practical and doctrinal vi
This thesis studies and identifies effects of income growth and income inequality on poverty in Honduras. A Poverty Reduction Strategy (PRS) was implemented in Honduras in 2001 with the goal to reduce poverty by half by 2015. Since carrying out of PRS, poverty and inequality has only decreased slightly and growth in income has been small. The effects of growth in income and changes in the income d
Objective: Testicular torsion (TT) is a medical emergency, difficult to identify solely through clinical evaluation. This study aims to develop an assessment algorithm with a safe lower threshold for complementary ultrasound. Material and methods: Males between 1 and 30 years of age assessed for suspected TT during the years 2019 – 2023 were retrospectively included. Clinical assessments were cond
Chemical signaling is ubiquitous and employs a variety of receptor types to detect the cacophony of molecules relevant for each living organism. Insects, our most diverse taxon, have evolved unique olfactory receptors with as little as 10% sequence identity between receptor types. We have identified a promiscuous volatile, 2-methyltetrahydro-3-furanone (coffee furanone), that elicits chemosensory
Power mechanisms and structures can shape adaptation outcomes, the measures adopted, and who is identified as requiring adaptation support. But to what extent does research recognise such power-adaptation linkages? Based on a systematic literature review, we enquire if and how the framing of power matters for climate change adaptation research and what the implications may be for practice. Our enq
