Background:In biological systems,biological diversity often displays a rapid turn-over across elevations.This defining feature has made mountains classic systems for studying the spatial variation in diversity.Because patterns of elevational diversity can vary among lineages and mountain systems it remains difficult to extrapolate findings from one montane region to another,or among lineages.In this study,we assessed patterns and drivers of avian diversity along an elevational gradient on the eastern slope of Mt.Gongga,the highest peak in the Hengduan Mountain Range in central China,and a mountain where comprehensive studies of avian diversity are still lacking.Methods:We surveyed bird species in eight 400-m elevational bands from 1200 to 4400 m a.s.l.between 2012 and 2017.To test the relationship between bird species richness and environmental factors,we examined the relative importance of seven ecological variables on breeding season distribution patterns:land area(LA),mean daily temperature(MDT),seasonal temperature range(STR),the mid-domain effect(MDE),seasonal precipitation(SP),invertebrate biomass(IB) and enhanced vegetation index(EVI).Climate data were obtained from five local meteorological stations and three temperature/relative humidity smart sensors in 2016.Results:A total of 219 bird species were recorded in the field,of which 204 were recorded during the breeding season(April–August).Species richness curves(calculated separately for total species,large-ranged species,and smallranged species) were all hump-shaped.Large-ranged species contributed more to the total species richness pattern than small-ranged species.EVI and IB were positively correlated with total species richness and small-ranged species richness.LA and MDT were positively correlated with small-ranged species richness,while STR and SP were negatively correlated with small-ranged species richness.MDE was positively correlated with large-ranged species richness.When we considered the combination of candidate factors using multiple regression models and model-averaging,total species richness and large-ranged species richness were correlated with STR(negative) and MDE(positive),while small-ranged species richness was correlated with STR(negative) and IB(positive).Conclusions:Although no single key factor or suite of factors could explain patterns of diversity,we found that MDE,IB and STR play important but varying roles in shaping the elevational richness patterns of different bird species categories.Model-averaging indicates that small-ranged species appear to be mostly influenced by IB,as opposed to large-ranged species,which exhibit patterns more consistent with the MDE model.Our data also indicate that the species richness varied between seasons,offering a promising direction for future work. 展开更多

New replacement names for the preoccupied mite genera Absentia Huang, 2001 and Venilia Kuznetsov, 1979 are proposed (Huangiella nom. nov. and Kuznetsovia nom. nov., respectively.). Fourteen further new replacement names are proposed for additional preoccupied generic names in the Arthropoda. These names are: Vailimia nom. nov., Millidgella nom. nov., and Nolavia nom. nov. in Araneae, Vadumasonium nom. nov. in Hymenoptera, Gridellia nom. nov., Vanstaronia nom. nov. and Veraniella nom. nov. in Coleoptera, Poletaevega nom. nov. in Trilobita, Vandelia nom. nov. in Isopoda, Gandoa nom. nov. and Vanuachela nom. nov. in Decapoda, and Crasquinia nom. nov., Oertlia nom. nov., and Soleaua nom. nov. in Ostracoda.

Staphylinoidea(Insecta:Coleoptera)is one of the most species-rich groups in animals,but its huge diversity can hardly be explained by the popular hypothesis(co-radiation with angiosperms)that applies to phytophagous beetles.We estimated the evolutionary mode of staphylinoid beetles and investigated the relationship between the evolutionary mode and palaeoclimate change,and thus the factors underlying the current biodiversity pattern of staphylinoid beetles.Our results demonstrate that staphylinoid beetles originated at around the Triassic-Jurassic bound and the current higher level clades underwent rapid evolution(indicated by increased diversification rate and decreased body size disparity)in the Jurassic and in the Cenozoic,both with low-energy climate,and they evolved much slower during the Cretaceous with high-energy climate.Climate factors,especially low 02 and high C02,promoted the diversification rate and among-clade body size disparification in the Jurassic.In the Cenozoic,however,climate factors had negative associations with diversification rate but little with body size disparification.Our present study does not support the explosion of staphylinoid beetles as a direct outcome of the Cretaceous Terrestrial Revolution(KTR).We suppose that occupying and diversifying in refuge niches associated with litter may elucidate rapid radiations of staphylinoid beetles in low-energy conditions. 展开更多

Article 59.1,of the International Code of Nomenclature for Algae,Fungi,and Plants(ICN;Melbourne Code),which addresses the nomenclature of pleomorphic fungi,became effective from 30 July 2011.Since that date,each fungal species can have one nomenclaturally correct name in a particular classification.All other previously used names for this species will be considered as synonyms.The older generic epithet takes priority over the younger name.Any widely used younger names proposed for use,must comply with Art.57.2 and their usage should be approved by the Nomenclature Committee for Fungi(NCF).In this paper,we list all genera currently accepted by us in Dothideomycetes(belonging to 23 orders and 110 families),including pleomorphic and nonpleomorphic genera.In the case of pleomorphic genera,we follow the rulings of the current ICN and propose single generic names for future usage.The taxonomic placements of 1261 genera are listed as an outline.Protected names and suppressed names for 34 pleomorphic genera are listed separately.Notes and justifications are provided for possible proposed names after the list of genera.Notes are also provided on recent advances in our understanding of asexual and sexual morph linkages in Dothideomycetes.A phylogenetic tree based on four gene analyses supported 23 orders and 75 families,while 35 families still lack molecular data. 展开更多

Following a large-scale phylogenetic study of the lichenized genus Cora(Basidiomycota:Agaricales:Hygrophoraceae),we formally describe 70 new species,honouring the seventieth birthday of David Leslie Hawksworth,one of the preeminent figures in mycology and lichenology in the past 50 years.Based on an updated phylogeny using the ITS fungal barcoding locus,we now recognize 189 taxa in a genus that until recently was considered to represent a single species;including this contribution,92 of these are formally recognized,including five taxa based on historical names or collections that have not been sequenced.Species of Cora can be recognized by a combination of morphological(size,colour,lobe configuration,surface hairs,hymenophore size and shape),anatomical(thallus thickness,cortex structure,photobiont type,hyphal papillae),and ecogeographical features(substrate,habitat,distribution),and a keytable allowing the identification of all accepted taxa is provided.The new species are:Cora accipiter Moncada,Madrin˜a´n&Lücking spec.nov.,C.applanata Moncada,Soto-Medina&Lücking spec.nov.,C.arachnodavidea Moncada,Dal Forno&Lücking spec.nov.,C.arborescens Dal Forno,Chaves&Lücking spec.nov.,C.arcabucana Moncada,C.Rodrı´guez&Lücking spec.nov.,C.aturucoa Lücking,Moncada&C.Vargas spec.nov.,C.auriculeslia Moncada,Ya´nez-Ayabaca&Lücking spec.nov.,C.barbifera Moncada,Patin˜o&Lücking spec.nov.,C.boleslia Lücking,E.Morales&Dal Forno spec.nov.,C.caliginosa Holgado,Rivas Plata&Perlmutter spec.nov.,C.campestris Dal Forno,Eliasaro&Spielmann spec.nov.,C.canari Nugra,Dal Forno&Lücking spec.nov.,C.caraana Lücking,Martins&Lucheta spec.nov.,C.casasolana Moncada,R.-E.Pe´rez&Lücking spec.nov.,C.caucensis Moncada,M.Gut.&Lücking spec.nov.,C.celestinoa Moncada,CabreraAmaya&Lücking spec.nov.,C.comaltepeca Moncada,R.-E.Pe´rez&Herrera-Camp.spec.nov.,C.corani Lücking,E.Morales&Dal Forno spec.nov.,C.corelleslia Moncada,A.Sua´rez-Corredor&Lücking spec.nov.,C.crispoleslia Moncada,J.Molina&Lücking spec.nov.,C.cuzcoensis Holgado,Rivas Plata&Perlmutter spec.nov.,C.dalehana Moncada,Madrin˜a´n&Lücking spec.nov.,C.davibogotana Lücking,Moncada&Coca spec.nov.,C.davicrinita Moncada,Madrin˜a´n&Lücking spec.nov.,C.davidia Moncada,L.Vargas&Lücking spec.nov.,C.dewisanti Moncada,A.Sua´rez-Corredor&Lücking spec.nov.,C.dulcis Moncada,R.-E.Pe´rez&Lücking spec.nov.,C.elephas Lücking,Moncada&L.Vargas spec.nov.,C.fuscodavidiana Lücking,Moncada&L.Vargas spec.nov.,C.garagoa Simijaca,Moncada&Lücking spec.nov.,C.gigantea Lücking,Moncada&Coca spec.nov.,C.gomeziana Dal Forno,Chaves&Lücking spec.nov.,C.guajalitensis Lücking,Robayo&Dal Forno spec.nov.,C.hafecesweorthensis Moncada,Lücking&R.Pela´ez spec.nov.,C.haledana Dal Forno,Chaves&Lücking spec.nov.,C.hawksworthiana Dal Forno,P.Nelson&Lücking spec.nov.,C.hochesuordensis Lücking,E.Morales&Dal Forno spec.nov.,C.hymenocarpa Lücking,Chaves&Lawrey spec.nov.,C.imi Lücking,Chaves&Lawrey spec.nov.,C.itabaiana Dal Forno,Aptroot&M.Ca´ceres spec.nov.,C.leslactuca nov.,C.maxima Wilk,Dal Forno&Lücking spec.nov.,C.minutula Lücking,Moncada&Ya´nez-Ayabaca spec.nov.,C.palaeotropica Weerakoon,Aptroot&Lücking spec.nov.,C.palustris Dal Forno,Chaves&Lücking spec.nov.,C.parabovei Dal Forno,Kukwa&Lücking spec.nov.,C.paraciferrii Lücking,Moncada&J.E.Hern.spec.nov.,C.paraminor Dal Forno,Chaves&Lücking spec.nov.,C.pastorum Moncada,Patin˜o&Lücking spec.nov.,C.pichinchensis Paredes,Jonitz&Dal Forno spec.nov.,C.pikynasa J.-M.Torres,Moncada&Lücking spec.nov.,C.pseudobovei Wilk,Dal Forno&Lücking spec.nov.,C.pseudocorani Lücking,E.Morales&Dal Forno spec.nov.,C.putumayensis L.J.Arias,Moncada&Lücking spec.nov.,C.quillacinga Moncada,F.Ortega&Lücking spec.nov.,C.rothesiorum Moncada,Madrin˜a´n&Lücking spec.nov.,C.rubrosanguinea Nugra,Moncada&Lücking spec.nov.,C.santacruzensis Dal Forno,Bungartz&Ya´nezAyabaca,spec.nov.,C.schizophylloides Moncada,C.Rodrı´guez&Lücking spec.nov.,C.smaragdina Lücking,Rivas Plata&Chaves spec.nov.,C.soredavidia Dal Forno,Marcelli&Lücking spec.nov.,C.subdavicrinita Moncada,J.Molina&Lücking spec.nov.,C.suturifera Nugra,Besal&Lücking spec.nov.,C.terrestris Dal Forno,Chaves&Lücking spec.nov.,C.terricoleslia Wilk,Dal Forno&Lücking spec.nov.,C.udebeceana Moncada,R.Pela´ez&Lücking,Moncada&R.Pela´ez spec.Lücking spec.nov.,C.urceolata Moncada,Coca&Lücking spec.nov.,C.verjonensis Lücking,Moncada&Dal Forno spec.nov.,C.viliewoa Lücking,Chaves&Soto-Medina spec.nov.,and C.yukiboa Mercado-Dı´az,Moncada&Lücking spec.nov.Furthermore,the taxonomic status of the recently described or recognized species C.arachnoidea,C.aspera,C.ciferrii,and C.reticulifera,is revised. 展开更多

Dothideomycetes comprise a highly diverse range of fungi characterized mainly by asci with two wall layers(bitunicate asci)and often with fissitunicate dehiscence.Many species are saprobes,with many asexual states comprising important plant pathogens.They are also endophytes,epiphytes,fungicolous,lichenized,or lichenicolous fungi.They occur in terrestrial,freshwater and marine habitats in almost every part of the world.We accept 105 families in Dothideomycetes with the new families Anteagloniaceae,Bambusicolaceae,Biatriosporaceae,Lichenoconiaceae,Muyocopronaceae,Paranectriellaceae,Roussoellaceae,Salsugineaceae,Seynesiopeltidaceae and Thyridariaceae introduced in this paper.Each family is provided with a description and notes,including asexual and asexual states,and if more than one genus is included,the type genus is also characterized.Each family is provided with at least one figure-plate,usually illustrating the type genus,a list of accepted genera,including asexual genera,and a key to these genera.A phylogenetic tree based on four gene combined analysis add support for 64 of the families and 22 orders,including the novel orders,Dyfrolomycetales,Lichenoconiales,Lichenotheliales,Monoblastiales,Natipusillales,Phaeotrichales and Strigulales.The paper is expected to provide a working document on Dothideomycetes which can be modified as new data comes to light.It is hoped that by illustrating types we provide stimulation and interest so that more work is carried out in this remarkable group of fungi. 展开更多

More than twenty species of lichenicolous fungi have been described in Phoma,a large anamorphic genus of primarily plant-associated pathogens with broad geographic distributions.We obtained nuclear and mitochondrial rDNA sequences from 19 fungal cultures isolated from specimens representing four described and two undescribed lichenicolous species in the genus.Our multilocus phylogeny indicates that lichenicolous Phoma species represent at least two phylogenetically distinct clades in the Phaeosphaeriaceae,one including a new species,Phoma puncteliae,isolated from a specimen of Punctelia rudecta collected inMaryland,USA,and another group of primarily lichenicolous species.This latter group includes four described lichenicolous Phoma species,an unidentified melanized rock fungus,and a new lichenicolous Phoma species isolated from Xanthomendoza species collected in Canada that we are naming P.xanthomendozae.Some specimens in this clade collected from different lichen genera and species were found to be very similar genetically,which calls into question the recent practice of recognizing lichenicolous Phoma species mainly by differences in host preference. 展开更多
