21st of February 2019: New study removes the fertilizer effect from climate reconstructions

At the end of February the article "Removing the no-analogue bias in modern accelerated tree growth leads to stronger medieval drought" by Tobias Scharnweber and other members of our working group appeared in Scientific Reports.

20th of February 2019: New project for digitalization in research

The State Excellence Program MV "Digitization in Research" supports the consortium "DIG-IT! Digitalisation of Natural Complexity to Solve Socially Relevant Ecological Problems" under the direction of Prof. Martin Wilmking. Over the next 3 years, researchers will have 2 million euros at their disposal to develop a methodological toolbox that can independently capture and categorize ecological image and audio data using machine learning techniques (deep convolutional neural networks). Partners are the Fraunhofer Institut für Grafische Datenverarbeitung Rostock (Prof. Uwe von Lukas), Biomathematik (Prof. Mareike Fischer) and working groups of the Institut für Botany und Landscape Ecology (Profs. Joosten, Kreyling, Wilmking) and the Zoological Institute and Museum (Prof. Gerald Kerth).

Extract from the jury vote:
"The DIG-IT! project aims to address urgent ecological issues through the use of digital technologies, with the evaluation of primary data posing a particular challenge. (...) The jury is convinced of the scientific excellence of the project. The idea of developing an ecological toolbox is particularly impressive. It also appreciates the approach of docking onto already existing excellent research alliances such as WETSCAPES and RESPONSE [DFG Research Training Group "Biological RESPONSEs to Novel and Changing Environments"] and using their findings above all to promote young scientists.

23th of October 2018: Humboldt Research Fellowship

In September of the current year (2018) the renowned Humboldt Research Fellowship for postdoctoral researchers was awarded to Canadian scientist Dr. Jill Harvey. The working group Landscape Ecology and Ecosystems Dynamics, lead by Prof. Martin Wilmking will be hosting her during her two year research stay. Jill Harvey comes from Victoria (Canada) and is performing research related to the resilience of forest ecosystems.

16th of October 2018: Ph.D. Colloquium

Mario Trouillier 's topic of his Ph.D. was „Individual white spruce (Picea glauca (Moench) Voss) growth limitations at treelines in Alaska“.  On October 16th he successfully defended his doctoral thesis. Congratulations!

4th of October 2018: Excursion to the "Ivenack oaks"

Also this year the DendroGreif working group enjoyed a one day short excursion to Ivenack, to take a look at the natural monument called "the Ivenack oaks". In this place, massive oaks (Quercus robur) with an estimated age of around 1000 years can be found, still standing and growing. These trees, possibly the oldest in Germany, are what remains of antique wood pastures where animals used to be fed during the medieval ages. This forest management strategy is still maintained in Ivenack, where tourists can see this land use formation. Since the year 2017 a 40 m high and 620 m long tree top path was built, which represents one of the highlights of the park.

28th of September 2018: Ph.D. Colloquium

Rohan Shetti succesfully defended his Ph.D. Dissertation on the 28th of September, entitled „Potential of shrubs in the evolving field of Arctic and Alpine Dendro-Ecology”. Rohan contributed to the field of arctic and alpine shrub dendrochronology, by assessing shrub growth and how it is affected by environmental conditions. Congratulations!

27th of September 2018: Article published in „Nature“ journal

Our working group, together with a large consortium of scientists working in the boreal forest and the tundra, published the results of an investigation on the effect of warming on functional plant traits across these important ecosystems. Under the lead of Dr. Anne Bjorkman, currently at the Senckenberg Biodiversity and Climate Researche Centre in Frankfurt (BiK-F), Germany, results were found that indicate that plants are growing taller under warming conditions, but other functional traits are lagging behind and not responding as predicted by models. This work helps unravel the way climate change is affecting biotic communities at the coldest extremes of the planet and will help to improve projections of changes in this important biome.

Mai 2018: Visiting Scientists from Chile

The DendroGreif group warmly welcomes Chilean guest scientists Ariel Muñoz-Navarro and Isabella Aguilera-Betti. Ariel and Isabella are doing research in the Pontifical Catholic University of Valparaíso and will stay in the DendroGreif lab until end of May 2018, supported by the DAAD. Ariel and Isabella work on questions about climate change impact on forests using dendroecology and dendrochemistry. During their stay, they will be working on improving the methodology for the identification of environmental pollutants and reconstruction of volcanic outbreaks with tree rings. Welcome Ariel and Isabella!

Mai 2018: TRACE Conference hosted in Greifswald

From the 24th to the 27th of April 2018, the DendroGreif group had the pleasure to host and organize this years’ TRACE (Tree Rings in Archaeology, Climatology and Ecology) conference with the Krupp-Kolleg as a venue. Around 170 participants from all over Europe and the world gathered in Greifswald to share their most novel work, build bridges and discuss about the science of tree rings. Organized mainly by Jelena Lange, Jill Harvey and Tobias Scharnweber from our DendroGreif group, we thank you for your efforts coordinating this unique scientific gathering!

5th of April 2018: DAAD funds 3 months visit of Dr. Ryszard Kaczka

DAAD, the German Academic Exchange Service, funds Dr. Ryszard Kaczka from the University of Silesia in Katowice, Poland, for a 3 month visit to our lab. Ryszard will work on identifying climatic extreme events in tree rings of Scots pine in Poland and Germany using a combined approach of ring width measurements and blue intensity. Welcome!

2nd of April 2018: New Ph.D. student

Timo Pampuch is our new Ph.D. student in the DFG funded Graduate school RESPONSE. He will continue with project B2, which deals with the plasticity and adaptive potential of white spruce to climate change in Alaska. Next to planning the field season up North, he will also start germination trials and climate manipulation experiments with white spruce here in Greifswald – welcome!

2nd of April 2018: New Postdoc

Dr. Alba Anadon-Rosell from Spain just started in our group as a postdoctoral research associate in the projects „Wetscapes“ and „FOMOSY-KK“. Alba will soon be looking at wood anatomical features of alnus trees, will visit all monitoring plots and get going with this year’s field work – welcome!

23th of March 2018: Visit from Minister Hesse to WETSCAPES

On the 23th of March the Minister of Education, Science and Culture in Mecklenburg-Vorpommern, Ms Birgit Hesse met the WETSCAPES project partners. During this meeting, the scientists within the project had the opportunity to showcase their work about peatlands and paludicultur. Click on the link to visit the WETSCAPES webpage.

26th of February 2018: Visiting Scientist Dr. Marina Gurskaya

The DendroGreif lab welcomes back Dr. Marina Gurskaya, visiting scientist from the Russian Academy of Sciences in Ekaterinburg, Russia.
