1. Theory predicts that the processes generating biodiversity after disturbance will change during succession. Comparisons of phylogenetic and functional (alpha and beta) diversity with taxonomic diversity can provide insights into the extent to which community assembly is driven by deterministic or stochastic processes, but comparative approaches have yet to be applied to successional systems. 2.
Aim In many cases, human colonization drastically modified the ecosystems of remote oceanic islands before scientists arrived to document the changes. Palaeoecological records before and after human colonization provide insights into the original ecosystems and an assessment of subsequent human impact. We used pollen analysis to compare the impact of 15th century colonization of the Azores with th

Instruktion Variabellista för EpiHealth Enkät, version 1.0.1, 2011-12-23 Utformning av dokumentet: Variablerna är uppdelade i tio fikar, en för metadata och de övriga enligt enkätens uppdelning av nio olika underkategorier. I varje filk så är variablerna därefter sorterade i alfabetisk ordning och kommer därmed inte i samma ordning som i enkäten. Variabelnamnen: I enkätens pdf-version står det ett

Background and objective: Prostate-specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT) is an evolving diagnostic tool for prostate cancer. There is a need to harmonise existing guidelines and reporting recommendations for PSMA PET/CT. The Standardised PSMA PET/CT Analysis and Reporting Consensus (SPARC) project aims to consolidate classifications and recommen
OBJECTIVES: The Sepsis-3 definition states the clinical criteria for sepsis but lacks clear definitions of the underlying infection. To address the lack of applicable definitions of infection for sepsis research, we propose new criteria, termed the Linder-Mellhammar criteria of infection (LMCI). The aim of this study was to validate these new infection criteria.DESIGN: A multicenter cohort study o
This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month
Jordens havsnivå förändras ständigt och dessa förändringar kan ha olika orsaker: i ett längre geologiskt tidsperspektiv är det processer i jordens inre som påverkar havsnivån, men i ett kortare perspektiv spelar till exempel tillväxten och avsmältningen av inlandsisar stor roll. Under kvartärtiden har den sistnämnda processen varit den dominerande vad gäller att påverka havsnivåerna: vid istider hResults from an investigation of relative sea-level changes from c. 11,000 cal. yr BP to the present in the Tasiusaq area, Inner Bredefjord, southwest Greenland, are presented in this thesis. Isolation sequences from two small lakes have been identified using stratigraphic analyses, XRF-scanning, loss on ignition and macrofossil analyses. Macrofossil and bulk samples have been dated in order to e
Abstract: Food availability sets the stage for incubation behaviour of a female bird and thereby indirectly determines the nest temperature, which in turn affects development and metabolism of avian embryos. Changes in development and metabolism in turn are known to influence offspring’s ability to adjust to environmental changes later in life. However, few studies have investigated the role of in
The last glacial period is characterized by a number of millennial climate events that have been identified in both Greenland and Antarctic ice cores and that are abrupt in Greenland climate records. The mechanisms governing this climate variability remain a puzzle that requires a precise synchronization of ice cores from the two hemispheres to be resolved. Previously, Greenland and Antarctic ice
Biogenic volatile organic compounds (BVOCs) such as isoprene constitute a large proportion of the global atmospheric oxidant sink. Their reactions in the atmosphere contribute to processes such as ozone production and secondary organic aerosol formation. However, over the tropical rainforest, where 50 % of the global emissions of BVOCs are believed to occur, atmospheric chemistry models have been
Changes in the geometry of ocean meridional overturning circulation (MOC) are crucial in controlling past changes of climate and the carbon inventory of the atmosphere. However, the accurate timing and global correlation of short-term glacial-to-deglacial changes of MOC in different ocean basins still present a major challenge. The fine structure of jumps and plateaus in atmospheric and planktic r
Glyoxalase I (GlxI) is an important enzyme that catalyzes the detoxification of methylglyoxal (MG) with the help of glutathione (H-SG). It is currently unclear whether MG and H-SG are substrates of GlxI or whether the enzyme processes hemithioacetal (HTA), which is nonenzymatically formed from MG and H-SG. Most previous studies have concentrated on the latter mechanism. Here, we study the two-subs
Bröst- och hudcancerceller sprider sig via lymfatiska systemet och fastnar i en eller två regionala sentinel lymfnoder (SLN) där de med stor sannolikhet växer till metastaser. Därför är SLN-biopsier och relaterade histopatologiska undersökningar viktiga vid cancerdiagnostiken för att bestämma sjukdomsstatus och att från denna kunna bestämma rätt behandling. Patienter vars lymfnoder innehåller spri
It is a textbook knowledge that charges of the same polarity repel each other. For two monovalent ions in the gas phase at a close contact this repulsive interaction amounts to hundreds of kilojoules per mole. In aqueous solutions, however, this Coulomb repulsion is strongly attenuated by a factor equal to the dielectric constant of the medium. The residual repulsion, which now amounts only to uni
Vegetation on land is globally taking up about 30% of the CO2 that is emitted by human activities (oceans take up 30%, while 40% remains in the atmosphere). This ability to store carbon in the vegetation and in the soil is very important to mitigate the climate changes, but all land based ecosystems are not carbon sinks. Ecosystems that are losing carbon needs to be further investigated, so we can
Tetra Pak is continuously working to increase the efficiency of the whole organisation. There is currently a general demand to improve by 20%. The number is not to be taken literately since efficiency is not defined nor is it specified how it should be measured. At Tetra Top the interpretation is that it is important to focus on efficiency and that it is up to individuals how and when it can be at
