Here, we explore the interdisciplinary merits of the ecosystem services concept by recruiting the notion of economics imperialism. We identify four different ways in which interdisciplinary concepts can fail as interdisciplinary concepts, three of which are associated with imperialism. First, interdisciplinary concepts can fail to be integrative, typically by being overtly flexible or vague. The r
Soil carbon (C) and nitrogen (N) availability depend on the breakdown of soil polymers such as lignin, chitin, and protein that represent the major fraction of soil C and N but are too large for immediate uptake by plants and microorganisms. Microorganisms may adjust the production of enzymes targeting different polymers to optimize the balance between C and N availability and demand, and for inst
Aims Genetic testing is needed for the formal diagnosis of maturity-onset diabetes of the young (MODY), but this is not widely available. If any MODY biomarkers were known, these could possibly be used as an alternative. Hepatocyte nuclear factor (HNF)-1alpha and HNF-4alpha regulate transcription of genes encoding complement 5 (C5), complement 8 (C8) and transthyretin (TTR), suggesting that these
Denna uppsats syftar till att undersöka i vilken utsträckning arbetstidslagstiftningen i Thailand och Sverige skyddar rätten till decent working time för hushållsarbetare. För att uppnå detta jämförs arbetstidslagstiftningen i de två länderna med hur decent working time definieras inom den internationella arbetsrätten. Denna analys utgör grunden för en diskussion om arbetstidsregleringen för hushåThis paper explores the extent to which working time legislation in Thailand and Sweden protects the right to decent working time for domestic workers. This is examined through a comparative analysis of the national working time legislation in the two countries and the parameters of decent working time established in international labor law. This is the basis for a subsequent discussion on the re
Den här uppsatsen syftar till att undersöka hur migrantarbetares rättigheter är skyddade inom folkrätt och mänskliga rättigheter. Efter en kort introduktion till internationell migration som fenomen samt de relevanta folkrättsliga normerna övergår uppsatsen till att behandla utlänningars ställning inom mänskliga rättigheter, genom en undersökning av tre av FN:s konventioner för mänskliga rättighetThis thesis examines the international protection of migrant workers. After a brief description of the migration phenomenon and the corresponding international legal framework, the position of aliens under human rights law is addressed through a review of three human rights conventions adopted within the framework of the United Nations. Following that, focus is turned to the international conventi
To stay within our planet’s limits and reach the United Nation’s Sustainable Development Goals, there is an urgent need to rethink our current and dominant systems. This thesis focuses on the food system, in particular, and explores how an overarching turnaround in the way we produce and consume food has the potential to trigger and steer a greater transition towards sustainability. However, this
Secondary hole-nesting birds that do not construct nest holes themselves and hence regularly breed in nest boxes constitute important model systems for field studies in many biological disciplines with hundreds of scientists and amateurs involved. Those research groups are spread over wide geographic areas that experience considerable variation in environmental conditions, and researchers provide
While many laboratory studies have focused on the short term effects of biochar addition to soil), there have been comparatively few tracing its longer term effects in the field. This study investigated the multiyear impact of biochar on crop performance and soil quality with specific emphasis on carbon (C) and nitrogen (N) cycling over a 3 y period. Biochar was added to an agricultural field at 0
A substantial portion of the carbon (C) fixed by the trees is allocated belowground to ectomycorrhizal (EM) symbionts, but this fraction usually declines after fertilization. The aim of the present study was to estimate the effect of optimal fertilization (including all the necessary nutrients) on the growth of EM fungi in young Norway spruce forests over a three year period. In addition, the amou
Longer periods of drought and droughts of higher intensity are expected to become increasingly frequent with future climate change. This has implications for the microbially mediated turnover of soil organic matter (SOM), which will feedback to the global C cycle. In this study, we addressed the microbial dynamics underlying the pulse of respiration following rewetting of dry soil, and how the dro
Cyanobacteria-plant symbioses play an important role in many ecosystems due to the fixation of atmospheric nitrogen (N) by the cyanobacterial symbiont. The ubiquitous feather moss Pleurozium schreberi (Brid.) Mitt. is colonized by cyanobacteria in boreal systems with low N deposition. Here, cyanobacteria fix substantial amounts of N-2 and represent a potential N source. The feather moss appears to
Feather mosses utilize various sources of nitrogen (N): they absorb N deposited on leaf tissue, they host N-2 fixing cyanobacteria, and they are able to take up N directly from soil. In addition to their importance as primary producers in boreal ecosystems, feather mosses play a significant role in N cycling. However, estimates of their ability to take up N from soil in situ are scarce. Further, c
The effect of pH on the instantaneous growth of soil bacterial communities was studied in five soils with different pH (4.5-7.8) using leucine (Leu) and thymidine (TdR) incorporation. The pH dependency of bacterial growth was modelled using three different unimodal functions, and the pH(opt) for growth and the pH range in which growth was > 50% of the optimal growth were compared. Leu and TdR inco
