VEC Science Day PhD Award to Linda Wilhelm
2012-03-14
Linda Wilhelm successfully convinced the jury of this year´s VEC Science Day to award her presentation with the PhD prize. Linda studies the diversity and assembly of microbial communities in glacier ice and high-alpine glacial streams in the working group of Tom Battin. The award will allow Linda to present her results at an international meeting. We congratulate!
Welcome: Hannes Peter and Nancy Burns
2012-03-13
We welcome Nancy Burns as a new Post-doc in the working group of Tom Battin. Nancy has already been reinforcing the priming task force since November 2011, and meanwhile is immersed hands-on in experimental work and data analysis. Hannes Peter finished his PhD in Uppsala Sweden in December 2011 and has joined the Battin working group in January 2012. Hannes will work on long-term data of carbon dioxide collected in the Lunzer Seebach.
Trichoptera Atlas
2012-01-12
A greatly expanded update of its successful predecessor (“Atlas of Austrian caddisfly larvae”), the nucleus of the "Atlas of Central European Trichoptera Larvae" follows an innovative concept by supplementing the proven dichotomous key with a completely new synoptic key. The synoptic design arranges similar species within one page, thereby supporting identification by the simultaneous use of several morphological details. As a further benefit, the geographical framework has been greatly expanded by including all caddisfly species thus far (2011) described in Austria, Germany and Switzerland. Due to the rich structure of the Central European species inventory and the text layout in both German and English this Atlas will be useful far beyond the immediate geographical target area defined above.
Introductory chapters deal with life cycles, larval morphology, case construction, collecting and preservation. Additional sections deal with biology, ecology, habitats and an extensive index including flight periods and head capsule widths of last instar larvae. A bibliography, new tables on geographical distribution based on ecoregions, saprobic indices, functional feeding types and zonal distribution patterns earmark the new Atlas as an important reference work for ecologists at Universities, Environmental Agencies, for biologists involved in monitoring and conservation biology and for all caddisfly enthusiasts. The Atlas has also been included in the canon of official identification tools when working with the Operational Taxa List as part of the Water Framework Directive of the European Union.
Format 21 x 28 cm, hardcover, 468 pages, more than 600 colour fotos. Available from Erik Mauch Verlag (Erik.Mauch.Verlag@t-online.de) and University bookshops (ISBN 978-3-00-032177-1).

Gene E. Likens Award for Ed Hall
2011-10-03

DeLi congratulates the lost colleague!
WELCOME: Mia Bengtsson
2011-05-31
Mia Bengtsson joins DeLi as a postdoc on June 1st through the project PRIMA (Priming in an aquatic ecosystem - Stream biofilms as hotspots for carbon cycling). PRIMA is a Marie Curie Intra-European Fellowship under the EU 7th framework program that will seek to uncover the significance of and the mechanisms behind the priming effect in stream biofilms. The priming effect refers to an increase in degradation of recalcitrant matter by microbial communities as a result of an input of labile organic matter. This phenomenon is widely recognized as an important factor for carbon cycling in soils, but has previously not been explicitly addressed in aquatic ecosystems. Mia is originally from Stockholm, Sweden but has lived and worked in Bergen, Norway for the past 4 years. She defended her PhD thesis on the topic of bacterial biofilm communities on marine kelps earlier this year. In PRIMA, she will work closely together with Tom Battin and Karoline Wagner.
Guest researcher Veronica Minaya
2011-05-03
Veronica Minaya, former student of the IPGL-course, will stay at Deli for the next two months and embark on her mission to save a collaborative project with the Singapore-Delft-Water-Alliance that was carried through in 2008.Veronica finished the IPGL course 2010 with a M.Sc. thesis on zoobenthos in the Mara River in Kenya. Her work in Vienna will now focus on HPLC-based carbohydrate analyses and transient storage modelling of data collected during experiments in the Lunzer Rinnen.

Aeroterrestrial algal communities on Viennese buildings
2010-10-29
Michael Schagerl´s Hochschuljubiläumsprojekt H2081_2010 "Algenflora auf Bauwerken in Wien" / "Aeroterrestrial algal communities on Viennese buildings" granted today. Michael Schagerl: "In this project, we will focus on algae growing on surfaces of buildings. We will collect algae within the vicinity of Vienna; environmental variables like exposition, humidity, irradiance or surface temperature will also be considered. After microscopical identification, clones will be cultured and sequenced. We will combine taxonomy done by traditional characters, phylogenetic analyses and environmental variables to gain more insight into keyfactors for structuring the algal communities."
