Microbial ecology has focused much on causes of between-site variation in community composition. By analysing five data-sets each of aquatic bacteria and phytoplankton, we demonstrated that microbial communities show a large degree of similarity in community composition and that abundant taxa were widespread, a typical pattern for many metazoan metacommunities. The regional abundance of taxa expla
This study describes a method to obtain a certain humidity level by a certain drying treatment. This treatment was applied on cement based materials in order to identify the critical moisture level above which ion transport can occur. The drying is performed in two steps, first in one direction to reach a certain moisture level and then in the opposite direction to identify if ions can move at thi
Introduction: Depression is frequent in ankylosing spondylitis (AS) patients. However, epidemiological data about the potential increase in risk are lacking. This study compares the rate of doctor-diagnosed depression in a well defined cohort of AS patients to the general population seeking care. Methods: The Skane Healthcare Register comprises healthcare data of each resident in Region Skane, Swe
The increased opportunity to choose one’s school of preference has been raised as a key factor in many countries to promote equal opportunities and a higher quality of education. This has been endorsed by policymakers who assume that students make well-informed rational choices and that students stress only academic quality when deciding which school to attend. If this is true, it will benefit sch
Genome-wide association (GWA) studies represent a powerful strategy for identifying susceptibility genes for complex diseases in human populations but results must be confirmed and replicated. Because of the close homology between mouse and human genomes, the mouse can be used to add evidence to genes suggested by human studies. We used the mouse quantitative trait loci (QTL) map to interpret resu
Partial migration, where populations are composed of both migratory and resident individuals, is extremely widespread across the animal kingdom. Researchers studying fish movements have long recognized that many fishes are partial migrants, however, no detailed taxonomic review has ever been published. In addition, previous work and synthesis has been hampered by a varied lexicon associated with t
Recent global change has had a substantial influence on the distribution of organisms, and many species are currently expanding their ranges. To evaluate the underlying processes, long-term data with good geographic resolution are essential. One important but generally overlooked data source is offered by the taxon-specific national catalogues of first provincial records that are kept in many coun
Based on a pharmacophore model of the benzodiazepine-binding site of GABA(A) receptors, a series of 2-aryl-2,6-dihydro[1,2,4]triazolo[4,3-c]quinazoline-3,5-diones (structure type I) were designed, synthesized, and identified as high-affinity ligands of the binding site. For several compounds, K(i) values of around 0.20nM were determined. They show a structural resemblance with the previously descr
Objective: This study evaluated the quality and readability of English-language internet information for adults with hearing impairment and their significant others. Design: Two keyword pairs (hearing loss and hearing aids) were entered into five country-specific versions of the most commonly used internet search engine in May 2011. Sample: For each of the 10 searches, the first 10 relevant websit
This article demonstrates how gender is implicated in climate governance through insights derived from gender and transition studies in combination, applied and illustrated through a study of climate governance in Sweden. The approach is constructive and uses central analytical concepts: transition arenas, niches, regimes and landscapes together with insights from gender research. The article prop
In this paper, we introduce a scale of differential operators which is shown to correspond canonically to a certain scale of solution kernels generalizing the classical Poisson kernel for the unit disc. The scale of kernels studied is very natural and appears in many places in mathematical analysis, such as in the theory of integral representations of biharmonic functions in the unit disc.
The response of microbial communities to long-term environmental change is poorly understood. Here, we study bacterioplankton communities in a unique system of coastal Antarctic lakes that were exposed to progressive long-term environmental change, using 454 pyrosequencing of the 16S rDNA gene (V3-V4 regions). At the time of formation, most of the studied lakes harbored marine-coastal microbial co
To provides an overall framework for thinking about the construction of carbon markets, we adopt James Der Derian's 'virtuous war' theory to develop an argument about carbon as a virtuous commodity. This refers to the close affinity between virtuality and virtue - the technological and the ethical - in the construction of carbon markets. The figure of virtuous carbon draws attention to both the fi
Dominance by cyanobacteria hampers human use of lakes and reservoirs worldwide. Previous studies indicate that excessive nutrient loading and warmer conditions promote dominance by cyanobacteria, but evidence from global scale field data has so far been scarce. Our analysis, based on a study of 143 lakes along a latitudinal transect ranging from subarctic Europe to southern South America, shows th
Background Therapeutic drug monitoring (TDM) of antibiotics in children is of fundamental importance for effective patient management. The use of dried blood spot (DBS) offers a number of advantages over conventional blood collection. The aim of this study is to develop and validate a method to measure piperacillin/tazobactam in DBS. Results The analysis was performed by using LC-MS/MS operating i
Microbial enzyme diversity is a key to understand many ecosystem processes. Whole metagenome sequencing (WMG) obtains information on functional genes, but it is costly and inefficient due to large amount of sequencing that is required. In this study, we have applied a captured metagenomics technique for functional genes in soil microorganisms, as an alternative to WMG. Large-scale targeting of fun
Fishing activity has been suggested to affect food web structure and functioning of aquatic ecosystems. Based on changes of the mean trophic level index of fishery catch, the present study demonstrates long-term ecosystem impacts of fisheries in Lake Chaohu, a freshwater lake in Anhui Province, China. The decline of mean trophic level (MTL) in the last five decades, coupled with a dramatic increas
The field of genetic diversity in protists, particularly phytoplankton, is under expansion. However, little is known regarding variation in genetic diversity within populations over time. The aim of our study was to investigate intrapopulation genetic diversity and genetic differentiation in the freshwater bloom-forming microalga Gonyostomum semen (Raphidophyceae). The study covered a 2-year perio
