We show how detailed vegetation plot data can be used to assess the potential impact of inundation by a proposed hydroelectricity dam in the Mokihinui gorge, New Zealand, on representation of natural forests. Specifically we ask: 1) How well are the types of forest represented Locally, regionally, and nationally; and 2) How does the number of distinct communities (i.e. beta diversity) in the target catchment compare with other catchments nationally? Methods: For local and regional comparisons plant species composition was recorded on 45 objectively located 400 m2 vegetation plots established in each of three gorges, with one being the proposed inundation area of the Mokihinui lower gorge. The fuzzy classification framework of noise clustering was used to assign these plots to a specific alliance and association of a pre-existing national-scale classification. NationaLly, we examined the relationship between the number of alliances and associations in a catchment and either catchment size or the number of plots per catchment by fitting Generalised Additive Models. Results: The four alliances and five associations that were observed in the Mokihinui lower gorge arepresent in the region but limited locally. One association was narrowly distributed nationally, but is the mostfrequent association in the Mokihinui lower gorge; inundation may have consequences of national importance to its long-term persistence. That the Mokihinui lower gorge area had nearly twice as many plots that could not be assigned to pre- existing alliances and associations than either the Mokihinui upper or the Karamea lower gorges and proportionally more than the national dataset emphasises the compositional distinctiveness of this gorge. These outlier plots in the Mokihinui lower gorge may be unsorted assemblages of species or reflect sampling bias or that native- dominated woody riparian vegetation is rare on the landscape. At a national scale, the Mokihinui catchment has a higher diversity of forest alliances and associations (i.e. beta-diversity) than predicted based on catchment size and sampling intensity. Conclusions: Our analytical approach demonstrates one transparent solution to a common conservation planning problem: assessing how well ecosystems that will be destroyed by a proposed land-use change are represented using a multi-scale spatial and compositional framework. We provide a useful tool for assessing potential consequences of land-use change that can help guide decision making.展开更多

This “Third Industrial Revolution” that connects digital sensor data analytics with adaptive services aims to transform data processing for timely decision support. The information is needed to improve irrigation scheduling, because global demand for food relies heavily on irrigation and global freshwater resources are diminishing. Previously, practitioners used visual indicators, infrequent measurements or predictive water balance models to estimate irrigation schedules. Visual indicators and infrequent measurements are approximate, and predictive models require many inputs so that likely cumulative errors cause inaccuracies in scheduling. In contrast, wireless sensor networks enable near real-time continuous measurement of soil moisture at targeted positions providing the site-specific information required for precision irrigation scheduling and efficient freshwater management. This paper describes and compares the structure, build and implementation of Crossbow, DigiMesh, and LoRa systems to deliver information on spatio-temporal soil water status and crop stress to practitioners over smart phones and webpages to improve management of irrigated land. Our study found that the newer LoRA system has advantages over the other systems, especially on flat land, with furthest node range of >10 km and advanced communication protocols that can penetrate dense vegetation. The mesh networking of the DigiMesh and Crossbow systems was preferred in hilly terrain to communicate around hills, and allows easy expansion of the network. The Crossbow system is simpler to install but presents difficulties for third party sensor integration. All systems allowed a step change in our ability to track dynamic changes in soil hydraulic properties and crop stress, to improve irrigation water use efficiency.展开更多

文摘Species and generic recognition in the order Xylariales has been uncertain due to lack of molecular data from authentic cultures,as well as overlapping morphological characteristics.In this study,we revise the families Graphostromataceae,Hypoxylaceae,Lopadostomataceae and Xylariaceae in Xylariales.Our study is based on DNA sequence data derived from living cultures of fresh isolates,data from GenBank and morphological observation of type and worldwide herbarium specimens.We also collected new specimens from Germany,Italy and Thailand.Combined analyses of ITS,LSU,RPB2 and b-tubulin sequence data were used to reconstruct the molecular phylogeny of the above families.Generic and familiar boundaries between these families are revised and presented in an updated combined phylogenetic tree.We accept six genera in Graphostromataceae,19 genera in Hypoxylaceae,four in Lopadostomataceae and 37 genera in Xylariaceae.Five genera previously treated in Xylariaceae are placed in Amphisphaeriales genera incertae sedis and seven genera are placed in Xylariales genera incertae sedis.Two genera are placed in Sordariomycetes genera incertae sedis,while four genera are placed as Xylariomycetidae genera incertae sedis.Three genera are considered as doubtful.Barrmaelia and Cannonia,presently included in Xylariaceae are transferred to Diatrypaceae and Coniochaetales respectively,based on their morphology and phylogeny.Areolospora and Myconeesia are excluded from Xylariaceae and synonymized with Phaeosporis and Anthostomella respectively.Updated descriptions and illustrations are provided for all taxa with notes provided on each genus.Excluded and doubtful genera are listed with notes on their taxonomy and phylogeny.Taxonomic keys are provided for all revised families with morphological details for genera within the families.

文摘Demarcation of family,genus and species boundaries in the Diaporthales has been tentative due to uninformative illus-trations and descriptions,overlapping morphological characteristics,misplacement or poor condition of type specimens and shortage of molecular data from ex-type cultures.In this study,we obtained the type specimens or other authentic specimens of diaporthalean taxa from worldwide fungaria.We examined,described and illustrated them.This study is based on morphological characters from type or authentic specimens,details from protologue and original illustrations and molecular data obtained from GenBank.Combined analyses of nrITS,nrLSU,RPB2 and TEF1-a sequence data were used to construct the molecular phylogeny.Additionally,we provided separate phylogenetic trees for families when necessary to show the generic distribution within these families based on suitable gene markers.Based on morphology and phylogeny,we treat 17 genera previously assigned to Diaporthales genera incertae sedis within several families.For some genera we have designated new generic types as they are lacking type species or type species have affiliations with other families.We exclude Anisomycopsis from Diaporthales and place it in Xylariomycetidae genera incertae sedis.Tirisporellaceae,which was previously placed in Tirisporellales is placed in Diaporthales based on phylogeny and morphology.A new combi-nation,Dendrostoma leiphaemia propose for Amphiporthe leiphaemia(Fr.)Butin.Based on the morphological characters and molecular data we accept 27 families and 138 genera within Diaporthales,24 genera in Diaporthales genera incertae sedis and one genus in Xylariomycetidae genera incertae sedis.We provide notes for genera in Diaporthales genera incertae sedis,and excluded and doubtful genera are listed with notes on their taxonomy and phylogeny.

文摘To date there is virtually no information available concerning the fungi associated with Tectona grandis(teak)(Lamiaceae)in Thailand.In this study,samples of microfungi were collected from both asymptomatic stems and dead wood,and symptomatic branches,stem and leaves of T.grandisfrom 27 sites in six provinces(Chiang Mai,Chiang Rai,Phayao,Phitsanulok,Phrae and Uttaradit Provinces).Morphology and combined multi-gene phylogeny(CAL,GAPDH,ITS,LSU,RPB2,SSU,TEF1 and TUB)were used to identify taxa.A total of 270 collections,representing 28 fungal species residing in 12 families,7 orders and 21 genera,with three species of uncertain taxonomic placement were identified.Of these,one family,three genera and 14 species are new to science.The new family,Pseudocoleodictyosporaceae is introduced based on its distinct lineage in the Dothideomycetes and its unique morphology as compared to Roussoellaceae and Torulaceae.The new genera are Neooccultibambusa,Pseudocoleodictyospora and Subglobosporium.The newly described species are Diaporthe neoraonikayaporum,D.tectonendophytica,D.tectonae,D.tectonigena,Hermatomyces tectonae,H.thailandica,Manoharachariella tectonae,Neooccultibambusa chiangraiensis,Pseudocoleodictyospora sukhothaiensis,Ps.tectonae,Ps.thailandica,Rhytidhysteron tectonae,Subglobosporium tectonae and Tubeufia tectonae.Fourteen species are known published taxa including Alternaria tillandsiae,Berkleasmium talaumae,Boerlagiomyces macrospora,Ceratocladium purpureogriseum,Fusarium solani,Helicoma siamense,Lasiodiplodia theobromae,Macrovalsaria megalospora,Paradictyoarthrinium diffractum,Phaeoacremonium italicum,Sphaeropsis eucalypticola,Stachybotrys levispora,St.renispora and Thaxteriellopsis lignicola.Epitypifications or reference specimens are designated for Boerlagiomyces macrospora and Macrovalsaria megalospora.Macrovalsaria megalospora is transferred from Botryosphaeriaceae to Dothideomycetes genus,incertae sedis based on taxonomy and phylogenetic analysis,which indicate it is distinct from Botryosphaeriaceae.All fungal species represent first reports on T.grandisin Thailand.New taxa and taxa incertae sedis,as well as known taxa which are established as reference specimens or epitypes,are presented with phylogenetic tree analyses,habitat,known distribution,material examined,full descriptions,notes and figures.Information is also provided for known taxa to add to the body of knowledge and to assist those wishing to study fungi occurring on T.grandis in future.

文摘Inaccurate taxonomic placement of fossils can lead to the accumulation of errors in molecular clock studies and their generated evolutionary lineages.There are limited fossil data that can be used in divergence time estimations.Therefore,reliable morphological characterization and taxonomical identification of fossil fungi are extremely important.Most fossils of Dothideomycetes and Sordariomycetes are from the early Cenozoic(66-23 Mya),with fewer from the late Mesozoic(174-145 Mya).However,it is hard to distinguish some fossil descriptions as photographs and illustrations are unclear;thus,the validity of using these fossils in calibrations of molecular clocks is problematic.This study brings scattered paleobiological data on selected fossil Ascomycota,using descriptions,fossil images and illustrations,coupled with recent age estimations,and taxonomic and phylogenetic affinity of extant species.As an integrated approach,this study summarizes a historical fossil outline with a reliable minimum age for 16 calibrating points viz.crown of Aigialus,Anzia,Aspergillus,Asterina,Calicium chlorosporum–C.nobile,Capnodiales,Chaenotheca,Colletotrichum,Diaporthales,Meliola,Ophiocordyceps,Microthyriales,Microthyrium,Muyocopron,Pezizomycotina and Stigmatomyces.A scheme of Ascomycota ancient lineages is also provided in order to improve divergence time estimations.

文摘Fungicolous fungi are a very large,diverse,ecological and trophic group of organisms that are associated with other fungi.This association occurs with species of different lineages across the fungal kingdom.They are recognized as symbionts,mycoparasites,saprotrophs,and even neutrals.Wherever fungi have been found,fungicolous taxa have also been found.Homogeneous environments favour the development of highly adapted and coevolved fungicolous species,which could have led to host-specificity aspects.As a primary consumer,fungicolous fungi decrease the turnaround time of certain nutrients in food webs,due to their special often-rapid life cycles.They may also significantly affect population dynamics and population sizes of their hosts in aquatic or terrestrial ecosystems.As mycoparasites of pathogenic fungi,some fungicolous fungi have been explored as biocontrol agents.They may also cause serious diseases of cultivated edible and medicinal mushrooms,decreasing both yield and quality.Fungicolous fungi could be used as model organisms that may help determine better understanding of species interactions,fungal evolution and divergence,and fungicolous mechanisms.This review summarizes our current understanding of fungicolous fungi,with a particular focus on the terminology,diversity,global distribution,and interaction with their hosts.We also provide a checklist including 1552 fungicolous fungal taxa so far recorded following the updated classification schemes.There is a need for further investigations on this ecologically important group of fungi to better understand their biology,ecological aspects,origin and divergence,hostspecificity and application in biocontrol.Accurate identification of these fungi as pathogens and their significance in quarantine purposes on the mushroom industry need further evaluations so that efficient control measures can be developed for better disease management purposes.

文摘The ascomycetous families,Didymosphaeriaceae and Montagnulaceae,have been treated in Pleosporales,Dothideomycetes,and both include saprobes,endophytes and pathogens associated with a wide variety of substrates worldwide.Didymosphaeriaceae was characterized by 1-septate ascospores and trabeculate pseudoparaphyses,mainly anastomosing above the asci,while species in Montagnulaceae had 1 to multi-septate ascospores and generally cellular pseudoparaphyses.In recent treatments,Bimuria,Didymocrea,Kalmusia,Karstenula,Montagnula,Paraphaeosphaeria,Paraconiothyrium and Letendraea were placed in Montagnulaceae,while only Didymosphaeria has been placed in Didymosphaeriaceae.New morphological and molecular data from recent collections have become available and thus the understanding of the families can be improved.Based on analyses of concatenated internal transcribed spacer(ITS)with LSU,SSU andβ-tubulin gene sequences,the taxonomy of the genera classified in these families are reassessed.Our phylogenetic analyses conclude that,the recently introduced Didymosphaeria rubi-ulmifolii with Paraconiothyrium brasi liense species complex,Alloconiothyrium,Bimuria,Deniquelata,Didymocrea,Kalmusia,Karstenula,Letendraea,Montagnula,Neokalmusia,Paraconiothyrium,Paraphaeosphaeria,Phaeodothis and Tremateia,forms a robust clade named here Didymosphaeriaceae.We therefore synonymize Montagnulaceae under Didymosphaeriaceae which is the oldest name and has priority and provide a update account of the family.Didymosphaeria is represented by Didymosphaeria rubi-ulmifolii.A new genus,Neokalmusia,is introduced in the family to accommodate the bambusi colous taxa Kalmusia brevispora and K.scabrispora.This introduction is based on molecular data coupled with morphology.One new species,Paraconiothyrium magnoliae and the sexual morph of Paraconiothyrium fuckelii,is also introduced.Julella and Barria are assigned to the family based on morphological similarity with Didymosphaeriaceae.Wilmia(previously referred to the Phaeosphaeriaceae)is synonymized under Letendraea(Didymosphaeriaceae).Furthermore,a new species,Letendraea cordylinicola,is introduced and placed in Didymosphaeriaceae based on phylogeny and morphology.The paraphyletic nature of Paraconiothyrium is partially resolved,but further sampling with fresh collections and molecular data of species in this genus are needed to obtain a natural classification.

文摘During a north–south latitudinal survey of aquatic fungi on submerged wood and herbaceous material in streams in the Asian region,we collected several hyphomycetous taxa.This paper is part of a series where we provide illustrated accounts of these taxa and place them in a natural classification in the fungi.DNA sequence based phylogenies in recent literature have shown that Dendryphion,Sporidesmium and Torula-like species are polyphyletic in the phylum Ascomycota and their taxonomyhas been problematic due to a lack of understanding of the importance of morphological characters used to delimit taxa,as well as the lack of ex-type or reference strains.Based on multi-locus phylogenies together with morphology,we propose the novel family Distoseptisporaceae(Sordariomycetes)and three novel genera Neotorula(Pleosporales,Dothideomycetes),Distoseptispora(Sordariomycetes)and Pseudosporidesmium(Sordariomycetes).In addition,Dendryphion aquaticum,D.submersum,Distoseptispora fluminicola,D.aquatica,Kirschsteiniothelia submersa,Neotorula aquatica,Sporidesmium aquaticum,S.submersum and S.fluminicola are introduced as new species.Pseudosporidesmium knawiae comb.nov.is proposed to accommodate Sporidesmium knawiae in Sordariomycetes.The polyphyletic nature of Dendryphion,Sporidesmium and Torula-like species are partially resolved,but further sampling with fresh collections and molecular data of species are needed to obtain a natural classification.

文摘Sordariomycetes is one of the largest classes of Ascomycota and is characterised by perithecial ascomata and inoperculate unitunicate asci.The class includes many important plant pathogens,as well as endophytes,saprobes,epiphytes,and fungicolous,lichenized or lichenicolous taxa.The class includes freshwater,marine and terrestrial taxa and has a worldwide distribution.This paper provides an updated outline of the Sordariomycetes and a backbone tree incorporating asexual and sexual genera in the class.Based on phylogeny and morphology we introduced three subclasses;Diaporthomycetidae,Lulworthiomycetidae and Meliolomycetidae and five orders;Amplistromatales,Annulatascales,Falcocladiales,Jobellisiales and Togniniales.The outline is based on literature to the end of 2014 and the backbone tree published in this paper.Notes for 397 taxa with information,such as new family and genera novelties,novel molecular data published since the Outline of Ascomycota 2009,and new links between sexual and asexual genera and thus synonymies,are provided.The Sordariomycetes now comprises six subclasses,28 orders,90 families and 1344 genera.In addition a list of 829 genera with uncertain placement in Sordariomycetesis also provided.

文摘Dictyosporiaceae fam.nov.is introduced to accommodate a holomorphic group of Dothideomycetes that are saprobes on decaying wood and plant debris in terrestrial and freshwater habitats.The sexual morph comprises Dictyosporium meiosporum,D.sexualis,Gregarithecium curvisporum,Pseudocoleophoma calamagrostidis and P.polygonicola.The sexual morphs are characterized by immersed to erumpent,superficial,globose to subglobose,dark brown to black ascomata,bitunicate asci,and septate,hyaline,sheathed ascospores.The asexual morphs are hyphomycetous with brown,multi-septate,cheirosporous conidia,produced from holoblastic conidiogenous cells,on micronematous conidiophores.Phylogenetic analyses of LSU,SSU and TEF1 sequence data place the genera with cheirospores in a monophyletic clade in the order Pleosporales.Phylogenetic analyses based on ITS sequence data show the family to comprise 44 distinct lineages that correspond to ten genera and an undetermined genus.Four new genera Dictyocheirospora,Dictyopalmispora,Jalapriya and Vikalpa,and eight new species Dictyocheirospora bannica,D.rotunda,D.vinaya,Dictyopalmispora palmae,Dictyosporium olivaceosporum,D.sexualis,Jalapriya pulchra,and Vikalpa lignicola,are introduced in the family.
文摘An account is provided of the world’s ten most feared fungi.Within areas of interest,we have organized the entries in the order of concern.We put four human pathogens first as this is of concern to most people.This is followed by fungi producing mycotoxins that are highly harmful for humans;Aspergillus flavus,the main producer of aflatoxins,was used as an example.Problems due to indoor air fungi may also directly affect our health and we use Stachybotrys chartarum as an example.Not everyone collects and eats edible mushrooms.However,fatalities caused by mushroom intoxications often make news headlines and therefore we include one of the most poisonous of all mushrooms,Amanita phalloides,as an example.We then move on to the fungi that damage our dwellings causing serious anxiety by rotting our timber structures and flooring.Serpula lacrymans,which causes dry rot is an excellent example.The next example serves to represent all plant and forest pathogens.Here we chose Austropuccinia psidii as it is causing devastating effects in Australia and will probably do likewise in New Zealand.Finally,we chose an important amphibian pathogen which is causing serious declines in the numbers of frogs and other amphibians worldwide.Although we target the top ten most feared fungi,numerous others are causing serious concern to human health,plant production,forestry,other animals and our factories and dwellings.By highlighting ten feared fungi as an example,we aim to promote public awareness of the cost and importance of fungi.
