Svamparnas diversitet och makroekologi kartlagda genom världsomspännande jordprover

En ny artikel i tidskriften Science bjuder på den hittills största och mest detaljerade kartläggningen av svamparnas mångfald. Ett forskarlag bestående av deltagare från 23 länder analyserade 365 jordprover från sex kontinenter med högeffektiv DNA-sekvenseringsteknik. Närmare 45,000 arter påträffades, av vilka mindre än 10% kunde identifieras till artnivå.

”Fjorton större grupper av arter kunde inte ens identifieras på klass-nivå.”, konstaterar Henrik Nilsson vid Göteborgs Universitet, medförfattare till studien.

Utöver det taxonomiska sprängstoffet, medförde den breda geografiska och klimatrelaterade samplingen att flera sedan länge etablerade hypoteser kring svamparnas biogeografi och makroekologi kunde prövas. Lite oväntat visade sig klimat- och jord-variabler såsom nederbördsmängd respektive pH vara avgörande för svampars kolonisering. Detta står i strid med dogmen att svampdiversiteten är intimt och oupplösligt kopplad till växtdiversiteten i varje område.

”Och fler omkullkastade dogmer lär det bli”, fortsätter Henrik, ”i takt med att vi nu har redskap att närma oss den eukaryota biodiversiteten och de processer som formar den på ett helt nytt, data-baserat sätt.”

Studien är ett exempel på den taxonomiska och ekologiska syntes som blir möjlig genom global sampling, högeffektiv DNA-sekvensering och världsomspännande samarbete. Vidare sätts svamparna som organismgrupp upp på agendan; i ljuset av studien framstår det som lätt försumligt att närma sig frågor kring ekosystemtjänster, klimatförändringar och makroekologi utan att inbegripa svampriket.

Summary in English

Fungi play major roles in ecosystem processes, but the determinants of fungal diversity and biogeographic patterns remain poorly understood. Using DNA metabarcoding data from hundreds of globally distributed soil samples, we demonstrate that fungal richness is decoupled from plant diversity. The plant-to-fungus richness ratio declines exponentially toward the poles. Climatic factors, followed by edaphic and spatial variables, constitute the best predictors of fungal richness and community composition at the global scale. Fungi show similar latitudinal diversity gradients to other organisms, with several notable exceptions. These findings advance our understanding of global fungal diversity patterns and permit integration of fungi into a general macroecological framework.

Swedish Systematics Days (November 24-25): Last chance to register!

Hi all,

Hurry up so you don’t miss the 10th Swedish Systematics Days, to be held in Göteborg 24-25 November!!

What has happened in systematics during the last 10 years? Where do we stand now and why? What will happen during the next 10 years? This will be a great opportunity to look back and look forward as a community.

Several excellent talks are already registered, but we want more people to make this a memorable event! There are still some time slots available for talks and many for posters. Or just come to listen and meet the others!

More information and registration: http://systematikforeningen.se/systematikdagarna2014/

LAST DAY TO REGISTER: NOVEMBER 15, 2014

 

News from DEST

Info from Hendrik Gheerardyn:

Dear all,

The Distributed European School of Taxonomy (DEST) http://www.taxonomytraining.eu/, an initiative under the CETAF umbrella and managed by RBINS, has launched its NEW website and training programme for 2014-2015!

Check out the Modern Taxonomy programme http://taxonomytraining.eu/content/modern-taxonomy-2014-2015 offering intensive theoretical courses in various subjects. Also, have a look at the Expert-in-training programme http://taxonomytraining.eu/content/expert-training-2014-2015 enabling trainees to develop and strengthen their taxonomic research skills through on-the-job-training.

Thank you for spreading the word!
With best regards,

European Journal of Taxonomy

Vi vil gerne reklamere for tidsskriftet European Journal of Taxonomy (http://www.europeanjournaloftaxonomy.eu/index.php/ejt), som Statens Naturhistoriske Museum udgiver i samarbejde med fem andre europæiske museer.

EJT er et rent elektronisk tidsskrift, som optager artikler om dyr, planter, og svampes taxonomi, også fossiler er dækket. Indholdet spænder fra beskrivelser af nye arter til store oversigter over forskellige grupper – indtil videre er mere end 400 nye arter beskrevet i EJT, herunder 20 nye arter som beskrives i nr. 100, som er forfattet af professor Henrik Enghoff. EJT udmærker sig ved at være et såkaldt ”diamant-niveau” Open Access tidsskrift. Dvs. at forfattere ikke betaler for at publicere i tidsskriftet, og læsere betaler ikke for at læse. Tidsskriftet finansieres fuldt og helt af de udgivende museer til glæde for det internationale forskersamfund.

Her ses den nyhed, som jeg har sat på DanBIF-portalen samt portalen for EU BON-projektet:

European Journal of Taxonomy #100

The European Journal of Taxonomy is a peer-reviewed international journal in descriptive taxonomy, covering the eukaryotic world. The content range from descriptions of new species to large inventories of different groups – so far more than 400 new species are described in EJT. Its content is fully electronic and Open Access. It is published and funded by a consortium of European natural history institutions. Neither authors nor readers have to pay fees.

The 100th issue of EJT, which was published 24 October 2014, comprises a beautifully illustrated monograph on African millipedes, adding 20 new species to our list of new taxa. Author is Professor Henrik Enghoff from The Natural History Museum of Denmark, University of Copenhagen.

No 100 (2014): A mountain of millipedes I: An endemic species-group of the genus Chaleponcus Attems, 1914, from the Udzungwa Mountains, Tanzania (Diplopoda, Spirostreptida, Odontopygidae). Henrik Enghoff.

EJT normally is an e-only journal, but on this occasion the editorial team has decided to print a limited number of hard copies, to be distributed amongst the Natural History Institutions around the world.

PhD Fellowship in Evolutionary Genomics at the Natural History Museum of Denmark

A fully funded Ph. D. fellowship on the evolution of plastid genomes in parasitic plants is available from January 1st, 2015 or soon thereafter in the Evolutionary Genomics group at the Natural History Museum of Denmark, Faculty of Science, University of Copenhagen, Denmark.

The fellowship will be an integral part of an interdisciplinary 3-year research project entitled: ”The Fate of Organellar Genomes in Parasitic Plants” financed by the Danish Council for Independent Research│Natural Sciences. The research project has an international scope with collaborators in the USA and Canada.

Project area

The Ph. D. student will primarily investigate the relationships between genome evolution (e.g., gene contents and genome structure) of plastids and levels of parasitism in seed plants in a phylogenomic context.

Primary supervisors are Gitte Petersen and Ole Seberg, The Natural History Museum of Denmark.
