Two new papers out from our group on archiannelids and meiofaunal evolution:
1. Laumer C, Bekkouche N, Kerbl A, Goetz F, Neves RC, Sørensen MV, Kristensen RM, Hejnol A, Dunn CW, Giribet G, Worsaae K. 2015. Spiralian phylogeny informs on evolution of microscopic lineages. Current Biology. http://www.cell.com/current-biology/abstract/S0960-9822(15)00795-2. We here reconstruct the phylogeny of Spiralia, the animal group including molluscs, annelids, flatworms, and many microscopic worms. The new tree suggests that some previously unsampled, interstitial Problematica originated through miniaturization from large-bodied ancestors, but also implies a primarily interstitial or meiofaunal origin for many lineages - possibly even Spiralia.

Candidates for the two announced PhD scholarships in invertebrate morphology: “Evolution and development of central organ systems in marine meiofauna” have been found and will start their projects 1. November 2012.
Alexandra Kerbl and Nicolas Bekkouche will soon start their two 3-year PhD positions at the Marine Biological Section, Department of Biology, University of Copenhagen. The positions will be jointly supervised by Katrine Worsaae, University of Copenhagen and Andreas Hejnol, Uni Sars Centre, Norway. The projects will address the origin of central body designs through detailed studies of, microscopic, complex animals of the lesser-studied spiralian lineages. Hereby we seek answers to central questions such as: Was the last common spiralian ancestor relatively large and complex as annelids and mollusks? Or was it microscopic consisting of low number of cells only? How complex and regionalized is the brain of microscopic animals?
Katrine Worsaae received 23/1-2012 a 4.87 mill. Dkr grant from Villum Fonden to the 4 year project:
HOW SMALL ANIMALS PROVIDE CLUES TO LARGE SCALE QUESTIONS: Problemstillinger omkring succesfulde 'kropsdesigns' oprindelse i dyreriget, angribes ved at studere og evolutionært placere udvalgte mikroskopiske dyregrupper fra den understuderede udviklingslinie ‘Spiralia' i et nyt livets træ. Herved vil vi teste hypoteser om de vigtigste egenskaber hos vores fælles stamform udfra undersøgelser af sammenlignelige mikroskopiske, komplekse dyr. Projektet, der fokuserer på kropsstørrelse, nervesystem, og leddeling, involverer molekylære slægtskabsanalyser af livets træ, samt genekspressions- og anatomiske studier. Bevillingen støtter projektet over fire år med bl.a. 2 Ph.D. studerende, 1 Post Doc, samt indkøb af konfokal mikroskop. More information available under 'project opportunities'.
Katrine Worsaae, PhD stud. Alejandro Martínez and her group house the first "INTERNATIONAL MEIOFAUNA EXPEDITION TO ANCHIALINE AND MARINE ENVIRONMENTS OF LANZAROTE, 1-23. OCTOBER 2011." 20 cavers, divers and scientists from 9 countries will attend the expedition, which is supported by the University of Copenhagen, the government of Lanzarote, the Turist Centre of Lanzarote, and the Carslberg Foundation. La Corona lava tube of Northern Lanzarote is among the largest and most diverse marine cave systems in the world, with many endemic and undescribed species - including remipedia.
Katrine Worsaae was onboard the schooner Activ, 1. September 2011, with the NorthEast Greenland Expedition 2011. She participated with the project "Meiofauna in the Fjord System". The culture house at 'Nordatlantens Brygge' will house an exhibition about the expedition 7-9. October 2011.
PhD Stud. Alejandro Martínez won the 'best student talk price' at the Int. Congress on Invertbrate Morphology (ICIM II) in Boston June, 2011.
