Here we review how evolving species concepts have been applied to understand yeast diversity.Initially,a phenotypic species concept was utilized taking into consideration morphological aspects of colonies and cells,and growth profiles.Later the biological species concept was added,which applied data from mating experiments.Biophysical measurements of DNA similarity between isolates were an early measure that became more broadly applied with the advent of sequencing technology,leading to a sequence-based species concept using comparisons of parts of the ribosomal DNA.At present phylogenetic species concepts that employ sequence data of rDNA and other genes are universally applied in fungal taxonomy,including yeasts,because various studies revealed a relatively good correlation between the biological species concept and sequence divergence.The application of genome information is becoming increasingly common,and we strongly recommend the use of complete,rather than draft genomes to improve our understanding of species and their genome and genetic dynamics.Complete genomes allow in-depth comparisons on the evolvability of genomes and,consequently,of the species to which they belong.Hybridization seems a relatively common phenomenon and has been observed in all major fungal lineages that contain yeasts.Note that hybrids may greatly differ in their post-hybridization development.Future in-depth studies,initially using some model species or complexes may shift the traditional species concept as isolated clusters of genetically compatible isolates to a cohesive speciation network in which such clusters are interconnected by genetic processes,such as hybridization.

molecular phylogenies using 1–4 gene regions and information on ecology,morphology and pigment chemistry were used in a partial revision of the agaric family Hygrophoraceae.The phylogenetically supported genera we recognize here in the Hygrophoraceae based on these and previous analyses are:Acantholichen,Ampulloclitocybe,Arrhenia,Cantharellula,Cantharocybe,Chromosera,Chrysomphalina,Cora,Corella,Cuphophyllus,Cyphellostereum,Dictyonema,Eonema,Gliophorus,Haasiella,Humidicutis,Hygroaster,Hygrocybe,Hygrophorus,Lichenomphalia,Neohygrocybe,Porpolomopsis and Pseudoarmillariella.A new genus that is sister to Chromosera is described as Gloioxanthomyces.Revisions were made at the ranks of subfamily,tribe,genus,subgenus,section and subsection.We present three new subfamilies,eight tribes(five new),eight subgenera(one new,one new combination and one stat.nov.),26 sections(five new and three new combinations and two stat.nov.)and 14 subsections(two new,two stat.nov.).Species of Chromosera,Gliophorus,Humidicutis,and Neohygrocybe are often treated within the genus Hygrocybe;we therefore provide valid names in both classification systems.We used a minimalist approach in transferring genera and creating new names and combinations.Consequently,we retain in the Hygrophoraceae the basal cuphophylloid grade comprising the genera Cuphophyllus,Ampulloclitocybe andCantharocybe,despite weak phylogenetic support.We include Aeruginospora and Semiomphalina in Hygrophoraceae based on morphology though molecular data are lacking.The lower hygrophoroid clade is basal to Hygrophoraceae s.s.,comprising the genera Aphroditeola,macrotyphula,Phyllotopsis,Pleurocybella,Sarcomyxa,Tricholomopsis and Typhula.

morphometric studies of 3D micro CT-scanned images can provide insights into the evolution of the brain and sensory structures but such data are still scarce for the most diverse mammalian order of rodents.From reviewed and new data,we tested for convergence to extreme aridity and high elevation in the sensory and brain morphology of rodents,from morphometric data from micro-CT X-ray scans of 174 crania of 16 species of three distantly re-lated African murid(soft-furred mice,Praomyini,laminate-toothed rats,Otomyini,and gerbils,Gerbillinae)clades and one North American cricetid(deer mice and white-footed mice,Peromyscus)clade.Recent studies demon-strated convergent evolution acting on the oval window area of the cochlea(enlarged in extremely arid-adapted species of Otomyini and Gerbillinae)and on endocranial volume(reduced in high elevation taxa of Otomyini and Peromyscus).However,contrary to our predictions,we did notfind evidence of convergence in brain struc-ture to aridity,or in the olfactory/respiratory system(turbinate bones)to high elevation.Brain structure differed,particularly in the petrosal lobules of the cerebellum and the olfactory bulbs,between Otomyini and Gerbillinae,with extreme arid-adapted species in each clade being highly divergent(not convergent)from other species in the same clade.We observed greater“packing”of the maxillary turbinate bones,which have important respiratory functions,in Peromyscus mice from high and low elevations compared to the high-elevation African Praomyini,but more complex patterns within Peromyscus,probably related to trade-offs in respiratory physiology and heat exchange in the nasal epithelium associated with high-elevation adaptation.

Lactobacillus are considered promising therapeutic methods for nonalcoholic fatty liver disease(NAFLD).The effects of two strains of Ltmosilactobacillus mucosae on NAFLD were investigated in this study.Fourweek-old male C57BL/6J mice were divided into 4 groups(n=8 per group,Control,model,FZJTZ26m3,FGSYC17L3).L.mucosae FZJTZ26m3 reduced the mice 's body weight,liver weight,and adipose tissue weight after 12 weeks of therapy.According to serum analysis,total cholesterol,triacylglycerol,and low-density lipoprotein cholesterol significantly decreased after L.mucosae FZJTZ26m3 intervention.Liver pathology showed that L.mucosae FZJTZ26m3 was effective to ameliorate lipid deposition in NAFLD mice.Additionally,the expression of the gene related to lipid metabolism in the liver and adipose tissue was analyzed,and the results indicated that L.mucosae FZJTZ26m3 could alleviate NAFLD by regulating lipid metabolism.Furthermore,the results of 16S rRNA gene sequencing revealed a drop in the relative abundance of Ruminococcaceae,which is linked to inflammation,but the relative abundance of a potential probiotic Akkermansia significantly increased after L.mucosae FZJTZ26m3 intervention.Generally,L.mucosae FZJTZ26m3 could be a candidate to prevent NAFLD.

The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies.Over the past decades,rapid development and affordability of molecular tools have tremendously improved insights of the fungal diversity in all ecosystems and habitats.Yet,in spite of the progress of molecular methods,knowledge about functional properties of the fungal taxa is vague and interpretation of environmental studies in an ecologically meaningful manner remains challenging.In order to facilitate functional assignments and ecological interpretation of environmental studies we introduce a user friendly traits and character database FungalTraits operating at genus and species hypothesis levels.Combining the information from previous efforts such as FUNGuild and FunFun together with involvement of expert knowledge,we reannotated 10,210 and 151 fungal and Stramenopila genera,respectively.This resulted in a stand-alone spreadsheet dataset covering 17 lifestyle related traits of fungal and Stramenopila genera,designed for rapid functional assignments of environmental stud-ies.In order to assign the trait states to fungal species hypotheses,the scientific community of experts manually categorised and assigned available trait information to 697,413 fungal ITS sequences.On the basis of those sequences we were able to summarise trait and host information into 92,623 fungal species hypotheses at 1%dissimilarity threshold.

Green coffee seeds from Colombia, Guatemala, India, Kenya, Papua New Guinea, Puerto Rico and Vietnam were sampled for the presence of fungal endophytes. Stions of surface sterilized seeds were plated on yeast malt agar, and fungal growth was isolated for subsequent DNA extraction and sequencing. Several fungal genera were isolated, including Acremonium, Aspergillus, Eurotium, Fusarium, Gibberella, Penicillium, Pseudozyma and an undescribed clavicipitaceous species. The biological activities that these fungi might be playing in coffee seeds remain unknown, but in other plants some of the genera isolated have been reported to protect against plant pathogens.

The development of reliable catalysts with both excellent activity and recyclability for carbon dioxide(CO_(2))hydrogenation is challenging.Herein,a ternary hybrid heterogeneous catalyst,involving mononuclear Ru complex,N,P-containing porous organic polymers(POPs),and mesoporous hollow carbon spheres(Ru^(3+)-POPs@mHCS)is reported for CO_(2)hydrogenation to formate.Based on comprehensive structural analyses,we demonstrated that Ru^(3+)-POPs were successfully immobilized within mHCS.The optimized Ru^(3+)-0.5POPs@mHCS catalyst,which was obtained with about 5 wt.%Ru^(3+)and 0.5 mmol POPs polymers confined into 0.3 g mHCS,exhibited high catalytic activity for CO_(2)hydrogenation to formate(turnover number(TON)>1,200 for 24 h under mild reaction conditions(4.0 mPa,120℃))and improved durability,compared to Ru^(3+)catalysts without POPs polymers(Ru^(3+)-mHCS)and unencapsulated mHCS(Ru^(3+)-0.5POPs)catalysts.The improved catalytic performance is attributed to the high surface area and large pore volume of mHCS which favors dispersion and stabilization of Ru^(3+)-POPs.Furthermore,the mHCS and POPs showed high CO_(2)adsorption ability.Ru^(3+)-POPs encapsulated into mHCS reduces the activation energy barrier for CO_(2)hydrogenation to formate.

Background Examining the health outcomes of veterans who have completed the United States Veterans Health Administration’s(VHA’s)Traumatic Brain Injury(TBI)Screening and Evaluation Program may aid in the refinement and improvement of clinical care initiatives within the VHA.This study compared self-reported physical functioning,cardiometabolic health conditions,and health care utilization patterns in million Veteran Program enrollees with TBI Screening and Evaluation Program data(collected between 2007 and 2019),with the goal of enhancing understanding of potentially modifiable health conditions in this population.methods In this observational cohort study,veterans(n=16,452)were grouped based on the diagnostic outcome of the TBI Screening and Evaluation Program:1)negative TBI screen(Screen^(-));2)positive TBI screen but no confirmed TBI diagnosis[Screen^(+)/Comprehensive TBI Evaluation(CTBIE)^(-)];or 3)positive TBI screen and confirmed TBI diagnosis(Screen^(+)/CTBIE^(+)).Chi-square tests and analysis of covariance were used to explore group differences in physical functioning,cardiometabolic health conditions,and health care utilization patterns,and logistic regressions were used to examine predictors of Screen^(+/-)and CTBIE^(+/-)group status.Results The results showed that veterans in the Screen^(+)/CTBIE^(-)and Screen^(+)/CTBIE^(+)groups generally reported poorer levels of physical functioning(P’smetabolic health conditions(P’s0.5)compared with the Screen-group;however,health outcomes were generally comparable between the Screen^(+)/CTBIE^(-)and Screen^(+)/CTBIE^(+)groups.Follow-up analyses confirmed that while physical functioning,hypertension,stroke,healthcare utilization,and prescription medication use reliably distinguished between the Screen-and Screen^(+)groups(P’s<0.02,OR’s 0.78 to 3.38),only physical functioning distinguished between the Screen^(+)/CTBIE^(-)and Screen^(+)/CTBI

In the United States, children are not meeting daily recommendationsfor 60 min of moderate・to・vigorous activity.1Because children spend a large portion of their days in school, ithas been further recommended that children accumulate 30 minof their physical activity (PA) during school hours.2 Our previousresearch has demonstrated with objective measures that only8%—9% of elementary school children meet this goal, with anaverage accumulation of 18 min/day.3,4 This finding is of concerngiven the numerous benefits that PA has not only on healthoutcomes,5-8 but also on academic achievement.9 For example,there is heightened awareness that children benefit from PAthroughout the school day in terms of attention to task, memory,behavior, and, ultimately, academic performance.10 Schooladministrators acknowledge this link, but still face barriers toincorporating PA for schoolchildren, including limited time andresources for physical education (PE) and recess.
