- The Global Consortium for the Classification of Fungi and fungus-like taxa is an international initiative of more than 550 mycologists to develop an electronic structure for the classification of these organisms. The members of the Consortium originate from 55 countries/regions worldwide, from a wide range of disciplines, and include senior, mid-career and early-career mycologists and plant pathologists. The Consortium will publish a biannual update of the Outline of Fungi and fungus-like taxa, to act as an international scheme for other scientists. Notes on all newly published taxa at or above the level of species will be prepared and published online on the Outline of Fungi website (https://www.outlineoffungi.org/), and these will be finally published in the biannual edition of the Outline of Fungi and fungus-like taxa. Comments on recent important taxonomic opinions on controversial topics will be included in the biannual outline. For example, 'to promote a more stable taxonomy in Fusarium given the divergences over its generic delimitation', or 'are there too many genera in the Boletales?' and even more importantly, 'what should be done with the tremendously diverse 'dark fungal taxa?' There are undeniable differences in mycologists' perceptions and opinions regarding species classification as well as the establishment of new species. Given the pluralistic nature of fungal taxonomy and its implications for species concepts and the nature of species, this consortium aims to provide a platform to better refine and stabilise fungal classification, taking into consideration views from different parties. In the future, a confidential voting system will be set up to gauge the opinions of all mycologists in the Consortium on important topics. The results of such surveys will be presented to the International Commission on the Taxonomy of Fungi (ICTF) and the Nomenclature Committee for Fungi (NCF) with opinions and percentages of votes for and against. Criticisms based on scientific evidence with regards to nomenclature, classifications, and taxonomic concepts will be welcomed, and any recommendations on specific taxonomic issues will also be encouraged; however, we will encourage professionally and ethically responsible criticisms of others' work. This biannual ongoing project will provide an outlet for advances in various topics of fungal classification, nomenclature, and taxonomic concepts and lead to a community-agreed classification scheme for the fungi and fungus-like taxa. Interested parties should contact the lead author if they would like to be involved in future outlines.

- The Basidiomycota constitutes a major phylum of the kingdom Fungi and is second in species numbers to the Ascomycota. The present work provides an overview of all validly published, currently used basidiomycete genera to date in a single document. An outline of all genera of Basidiomycota is provided, which includes 1928 currently used genera names, with 1263 synonyms, which are distributed in 241 families, 68 orders, 18 classes and four subphyla. We provide brief notes for each accepted genus including information on classification, number of accepted species, type species, life mode, habitat, distribution, and sequence information. Furthermore, three phylogenetic analyses with combined LSU, SSU, 5.8s, rpb1, rpb2, and ef1 datasets for the subphyla Agaricomycotina, Pucciniomycotina and Ustilaginomycotina are conducted, respectively. Divergence time estimates are provided to the family level with 632 species from 62 orders, 168 families and 605 genera. Our study indicates that the divergence times of the subphyla in Basidiomycota are 406-430 Mya, classes are 211-383 Mya, and orders are 99-323 Mya, which are largely consistent with previous studies. In this study, all phylogenetically supported families were dated, with the families of Agaricomycotina diverging from 27-178 Mya, Pucciniomycotina from 85-222 Mya, and Ustilaginomycotina from 79-177 Mya. Divergence times as additional criterion in ranking provide additional evidence to resolve taxonomic problems in the Basidiomycota taxonomic system, and also provide a better understanding of theirphylogeny and evolution.

- BACKGROUND: Limited comparative studies assessing the health-related quality of life (HRQL) in heart failure (HF) patients with preserved vs. low ejection fraction (LVEF) have been disparate. AIMS: The aims of this study were a) to characterize HRQL in a large population of HF patients with preserved and low LVEF and b) to determine the factors associated with worse HRQL. METHODS: Patients with symptomatic HF (NYHA Class II-IV) enrolled in the Candesartan in Heart Failure: Assessment of Reduction in Mortality and Morbidity (CHARM) HRQL study completed the Minnesota Living with Heart Failure questionnaire at randomization. Patients were stratified into 2 HF cohorts: preserved LVEF (>40%) and low LVEF (

Global diversity and distribution of macrofungi
- 2007

Ingår i: Biodiversity and Conservation. - 0960-3115. ; 16:1, s. 37-48
-
Tidskriftsartikel (refereegranskat)abstract
- Data on macrofungal diversity and distribution patterns were compiled for major geographical regions of the world. Macrofungi are defined here to include ascomycetes and basidiomycetes with large, easily observed spore-bearing structures that form above or below ground. Each coauthor either provided data on a particular taxonomic group of macrofungi or information on the macrofungi of a specific geographic area. We then employed a meta-analysis to investigate species overlaps between areas, levels of endemism, centers of diversity, and estimated percent of species known for each taxonomic group for each geographic area and for the combined macrofungal data set. Thus, the study provides both a meta-analysis of current data and a gap assessment to help identify research needs. In all, 21,679 names of macrofungi were compiled. The percentage of unique names for each region ranged from 37% for temperate Asia to 72% for Australasia. Approximately 35,000 macrofungal species were estimated to be "unknown" by the contributing authors. This would give an estimated total of 56,679 macrofungi. Our compiled species list does not include data from most of S.E. Europe, Africa, western Asia, or tropical eastern Asia. Even so, combining our list of names with the estimates from contributing authors is in line with our calculated estimate of between 53,000 and 110,000 macrofungal species derived using plant/macrofungal species ratio data. The estimates developed in this study are consistent with a hypothesis of high overall fungal species diversity.

Considerations and consequences of allowing DNA sequence data as types of fungal taxa

- Nomenclatural type definitions are one of the most important concepts in biological nomenclature. Being physical objects that can be re-studied by other researchers, types permanently link taxonomy (an artificial agreement to classify biological diversity) with nomenclature (an artificial agreement to name biological diversity). Two proposals to amend the International Code of Nomenclature for algae, fungi, and plants (ICN), allowing DNA sequences alone (of any region and extent) to serve as types of taxon names for voucherless fungi (mainly putative taxa from environmental DNA sequences), have been submitted to be voted on at the 11th International Mycological Congress (Puerto Rico, July 2018). We consider various genetic processes affecting the distribution of alleles among taxa and find that alleles may not consistently and uniquely represent the species within which they are contained. Should the proposals be accepted, the meaning of nomenclatural types would change in a fundamental way from physical objects as sources of data to the data themselves. Such changes are conducive to irreproducible science, the potential typification on artefactual data, and massive creation of names with low information content, ultimately causing nomenclatural instability and unnecessary work for future researchers that would stall future explorations of fungal diversity. We conclude that the acceptance of DNA sequences alone as types of names of taxa, under the terms used in the current proposals, is unnecessary and would not solve the problem of naming putative taxa known only from DNA sequences in a scientifically defensible way. As an alternative, we highlight the use of formulas for naming putative taxa (candidate taxa) that do not require any modification of the ICN.

- Land-based abalone aquaculture in South Africa, based on the local species Haliotis midae, started in the early 1990s and has grown rapidly in the last decade, with 13 commercial farms now producing over 850 t per annum. Over 6,000 t per annum of kelp Ecklonia maxima are now harvested for this purpose, and some kelp beds are reaching maximum sustainable limits. Research into seaweed aquacultureas feed (Ulva and some Gracilaria) for abalone started in the late 1990s on the southeast coast (where thereare no kelp beds) using abalone waste water. A growing body of evidence suggests that a mixed diet of kelp plus other seaweeds can give growth rates at least as good ascompound feed, and can improve abalone quality and reduce parasite loads. A pilot scale Ulva lactuca and abalone integrated recirculation unit using 25% recirculation was designed and built on the south west coast of South Africa using one 12,000-L abalone tank containing 13,200 15±2.5 g abalone, connected to two 3,000-L seaweed tanks containing an initial starting biomass of 10 kg of seaweed, replicated 3 times. In an 18-month period, there were no significant differences in abalone health or growth rates, sediment build up and composition, mobile macro fauna densities and species between the recirculation or the flowthroug hunits. Transfer of oxygen generated by the seaweeds to the abalone tanks was poor, resulting in the recirculated abalone tanks having lower (33%) dissolved oxygen concentrations than a comparable flow-through abalone unit. Seaweed nutrient content and specific growth rates in the units were comparable to seaweeds cultivated in fertilized effluent (SGR=3.2±3.4%.day−1; Yield=0.2±0.19 kg.m2.day−1). Indications were that at this low recirculation ratio the seaweeds in the units were nutrient limited and that there were no negative effects to the abalone being cultivated insuch a recirculation unit at this recirculation ratio.

The Persistence of Fee Dispersion among Mutual Funds

Ingår i: Review of Finance. - : Oxford University Press (OUP): Policy F - Oxford Open Option D. - 1573-692X .- 1572-3097. ; 25:2, s. 365-402

- Previous work shows large differences in fees for SandP 500 index funds and other funds and suggests that investors suffer wealth losses investing in high-fee funds when similar low-fee funds are available. In contrast, the neoclassical model of mutual funds (Berk and van Binsbergen, 2015, J. Financ. Econ., 118, 1-20) argues that percentage fees are irrelevant, as fund size will adjust in equilibrium such that net alphas are equal to zero. We show that fees matter from an investor perspective. We document (i) a strong negative association between net-of-fee fund performance and fees in a sample of all US and international equity funds, (ii) economically large, robust, persistent, and pervasive fee dispersion in the mutual fund industry, and (iii) important economic effects for investors. During the sample period, the mutual fund industry has generated a total value lost (i.e., a negative net value added) of 125 billion USD, coming predominantly from high-fee funds. © 2020 The Author(s).

Seascape Configuration and Fine-Scale Habitat Complexity Shape Parrotfish Distribution and Function across a Coral Reef Lagoon
- 2020

Ingår i: Diversity. - : MDPI AG. - 1424-2818. ; 12:10

Tidskriftsartikel (refereegranskat)abstract
- Structural complexity spanning fine to broad spatial scales can influence the distribution and activity of key organisms within marine ecosystems. However, the relative importance of hard (e.g., corals) and/or soft (e.g., macroalgae) structural complexity for marine organisms is often unclear. This study shows how both broad-scale (seascape configuration of coral structure) and fine-scale habitat complexity (structure height, number of holes, and presence of macroalgae) can influence the abundance and spatial ecology of reef fish. Underwater visual census of fish, surveys of habitats, remote underwater videos, and behavioral observations by following individual fish were used to quantify fine-scale habitat characteristics (e.g., complexity, coral structure height, macroalgae presence) and the abundance, size structure, and behavior (rates of herbivory, tortuosity ratios and total distance travelled) of abundant parrotfish. Both seascape configuration and macroalgae influenced the patterns of fish abundance and rates of herbivory. However, these relationships varied with trophic groups and ontogenetic stages. Abundance of adult and intermediate-phase parrotfishes was positively influenced by densely aggregated coral structures, whereas juvenile abundance was positively influenced by the presence of macroalgae. Foraging path and bite rates of an abundant parrotfish, Chlorurus spilurus, were not influenced by coral structure configuration or height, but the presence of macroalgae increased the bite rates of all juvenile parrotfish. Our results suggest that a combination of seascape configuration, fine-scale habitat complexity, and microhabitat selectivity influence reef fish community structure and foraging behavior, thus altering herbivory. However, these relationships can differ among functional groups of fish and life-history stages. Information on these fish–habitat interactions is critical for identifying habitats that facilitate ecological functions and ensures the successful management and conservation of essential habitats.

Forskningsöversikt (refereegranskat)abstract
- Enzymes and whole cells are being increasingly applied in research and industry, but the adoption of biocatalysis relies strongly on useful scientific literature. Unfortunately, too many published papers lack essential information needed to reproduce and understand the results. Here, members of the scientific committee of the European Federation of Biotechnology Section on Applied Biocatalysis (ESAB) provide practical guidelines for reporting experiments. The document embraces the recommendations of the STRENDA initiative (Standards for Reporting Enzymology Data) in the context of pure enzymology and provides further guidelines and explanations on topics of crucial relevance for biocatalysis. In particular, guidelines are given on issues such as the selectivity, specificity, productivity and stability of biocatalysts, as well as on methodological problems related to reactions in multiphase systems. We believe that adoption and use of these guidelines could greatly increase the value and impact of published work in biocatalysis, and hence promote the further growth of applications.

Type of treatment and estimation of time spent on dental trauma--a longitudinal and retrospective study
- 1998

Ingår i: Swedish Dental Journal. - 0347-9994. ; 22:1-2, s. 47-60

Tidskriftsartikel (refereegranskat)abstract
- The consequences of traumatic tooth injuries (dental trauma) are time-consuming and costly treatment and follow-ups, of which our knowledge is scarce. Consequently the aim of the present study was to measure the total time of treatment of uncomplicated and complicated traumas to primary and permanent teeth. The study was performed in three steps based on a randomly selected sample of Danish children and adolescents living in the municipality of Copenhagen, Denmark: (I) A descriptive analysis of traumas affecting 106 children and adolescents all born in 1970 and randomly chosen among the total number of patients treated. Treatments took place between 1972 and 1988. (II) A study of the time and frequency of different types of emergency and planned treatment estimated by 14 dentists employed by the municipal dental service. (III) Calculation of the total treatment time on the basis of the results from (I) and (II). The most common traumas were luxations of primary teeth and fractures of permanent teeth. The most frequent treatments dealt with were uncomplicated crown fractures and luxations followed by other different diagnoses of complicated traumas. The treatment time for primary teeth for uncomplicated traumas were used mostly for information, while the time for complicated traumas was used for follow-ups. The treatment time for traumas to permanent teeth was dominated by follow-ups, irrespective of the complication status. Only 3% of uncomplicated traumas of permanent teeth resulted in endodontic treatment, compared to 67% with complicated traumas. Uncomplicated traumas to primary teeth required a total of 2.5 visits and 0.8 hrs treatment time, while 4.3 visits and 1.6 hrs per individual were used for complicated traumas. For permanent teeth with uncomplicated traumas 9.2 visits and 3.2 hrs were required, and for complicated traumas 16.4 visits and 8.5 hrs per individual. The respective treatment times for complicated traumas for primary and permanent teeth were 2.0 and 2.7 times higher, compared to the corresponding uncomplicated traumas. There were no gender differences in type of injury and number of visits for injuries to primary and permanent teeth.

- People in the Arctic as well as fishermen on the polluted Swedish east coast are highly exposed to persistent organic pollutants (POPs). These compounds have been shown to affect the sperm Y:X chromosome ratio. In present study, the aim was to investigate whether polychlorinated biphenyl (PCB) congeners and 1,1,-dichloro-2,2,-bis(p-chlorophenyl)ethane (p,p'-DDE) influence sperm sex chromosome ratio in Faroese men, and whether these men differ regarding Y:X ratio compared to Greenland Inuit and Swedish fishermen. The study population (n=449) consisted of young men from the general population (n=276) as well as proven fertile men (n=173). The Y:X ratio was assessed by fluorescent in situ hybridization. Serum concentrations of POPs were measured using gas chromatography. Associations between POP concentrations and Y:X ratio were calculated using linear and non-linear regression models as well as trend analysis and pairwise comparison of exposure data categorized into quartiles. The selected POPs were associated with Y:X ratio in fertile Faroese men, but not in the total population; p,p'-DDE (95% CI for B=-0.005 to -0.001, p=0.005) and ΣPCB (95% CI for B=-0.005 to -0.001, p=0.012). Since p,p'-DDE and ΣPCB correlated significantly (r=0.927, p<0.001), the results involving the exposure variables can be regarded as a single finding. The Y:X ratio for the total Faroese population was 0.500±0.018, which was statistically significantly lower than in both Inuit and Swedish fishermen (0.512 for both). In conclusion, Faroese men presented with lower Y:X ratio than Greenland Inuit and Swedish fishermen. Although no direct health effects are expected due to the lower Faroese Y:X ratio, it could be indicative of adverse effects on the reproductive system.

- Background Patients with atrial fibrillation (AF) can be severely incapacitated by symptoms, but validated symptom measures are lacking. The aim of this study was to develop an AF-specific symptom questionnaire (AFSymp(TM)). Methods Following a literature review, qualitative interviews with 91 patients (United States [US], n = 30; United Kingdom [UK], n = 16; France, n = 15; Germany, n = 15; Japan, n = 15) with paroxysmal, persistent, and permanent AF were conducted to identify emergent concepts and to develop the items and response options for the AFSymp(TM). Clinical experts (n = 21) in the US, the UK, France, Germany, and Japan provided feedback on the most clinically relevant symptoms via an email survey. Cognitive interviews with 30 patients were conducted to evaluate content validity. A prospective, observational, psychometric evaluation study (n = 313) consisting of two study visits was performed at 32 sites across the US. Results After item reduction, the AFSymp(TM) consisted of 11 items with a 1-week recall period. Exploratory and confirmatory factor analysis resulted in three subscales (heart symptoms, tiredness, chest discomfort) and two items: dizziness and shortness of breath. Internal consistency was strong across subscales (Cronbach's a 0.82-0.91). The test-retest reliability of items and subscales was acceptable (intra-class correlation [ICC] 0.58-0.78). The reproducibility of the single global score was strong (ICC 0.78). The construct and known-groups validity was acceptable. Conclusion The AFSymp(TM) demonstrates evidence of reliability and validity as a comprehensive measure of AF symptoms that can be used to assess patient outcomes in clinical and research settings. More research is needed to evaluate the instrument's responsiveness.

Tidskriftsartikel (refereegranskat)abstract
- A simple and easy-to-use extraction method for aqueous samples based on hollow fibre-supported liquid membrane (HF-SLM) followed by liquid chromatography-mass spectrometry/mass spectrometry (LC-MS/MS) was developed to determine ivermectin and transformation products, the monosaccharide (TP1) and the aglycon of ivermectin (TP2). The proposed method attained enrichment factors up to 80, after optimising parameters, such as fibre length, organic solvent, stirring speed, salt level, pH in samples/fibre, extraction time and fibre emptying technique. Method validation with tap and lake water samples provided good linearity and detection limits of 0.2, 1.6 and 0.9 mu g/l for ivermectin, TP1 and TP2 in lake water with RSD below 15%.
