Ernsthaft? Ernsthaft!

Wie würden Sie reagieren, wenn Sie jemand fragt, ob Sie sich mal Stimmen von Maikäferlarven anhören möchten? Mit genau dieser Frage habe ich letzte Woche Besucher beim Hessentag in Rüsselsheim angesprochen. Ich hatte dort die Möglichkeit zusammen mit vier meiner Feldmaikäferengerlinge, mein Projekt CH4ScarabDetect am Stand von ProLoewe im Rahmen des Schwerpunktes FACE2FACE den Hessentagsbesuchern zu präsentieren.

Die Reaktion der Leute auf meine Frage verlief im Großen und Ganzen immer nach dem gleichen Schema. Erst erkundigte man sich, ob man die Frage richtig verstanden hatte. Dann ließ man sich versichern, dass das ganze kein Scherz ist („Sie wollen mich jetzt nicht veräppeln, oder?) und wer dann noch Interesse hatte, der kam auch zu meinem Stand und setzte sich die Kopfhörer auf.


…wo es zwischenzeitlich auch mal eng werden konnte.

Die Lautäußerungen von Engerlingen sind in keiner Weise mit den Stimmen vergleichbar wie man sie von Säugetieren kennt. Aber Engerlinge sind in der Lage absichtlich Laute zur Kommunikation im Boden von sich zu geben. Der Fachausdruck dafür ist Stridulation. Bei der Stridulation werden zwei bewegliche Körperteile gegeneinander gerieben, wodurch Laute erzeugt werden. Bei den Maikäferengerlingen werden die Mundwerkzeuge, die Mandibeln, gegeneinander gerieben. Man kann also sagen, sie unterhalten sich untereinander durch Zähne- und Kieferknirschen. Davon überzeugte sich unter anderem auch der hessische Kultusminister Alexander Lorz.

Innerhalb des letzten Jahres habe ich schon unzählige Audioaufnahmen von Engerlingen im Boden gesammelt (dafür steckt man einfach ein Mikrofon in den Boden), aber ich habe keine Ahnung was die Engerlinge mit ihren Lauten bezwecken wollen. Für mich dienen die Audio-Aufnahmen derzeit in erster Linie dazu eine Methode zu entwickeln, um die Engerlinge im Boden einfacher zu finden, damit ich anschließend ihre Methanemissionen bestimmen kann. Wenn ich an den Punkt angekommen war, an dem ich den Besuchern erzählte, dass Engerlinge Methan genauso produzieren und abgeben können wie Kühe, kam meistens der zweite ungläubige Blick („Ernsthaft? Wie kommt man auf die Idee, sowas zu erforschen?“) Tja, auf diese Frage hatte ich nicht wirklich eine Antwort, aber es war definitiv keine Schnapsidee. Davon überzeugte sich auch die hessische Milchkönigin.

Wenn Sie mal Engerlinge beim Fressen beobachten und belauschen möchten, oder mehr über Methanemissionen und Bodengase im Allgemeinen erfahren möchten, besuchen Sie mich morgen oder am Samstag auf dem Hessentag in Rüsselsheim. Gerne stelle ich Ihnen mein Projekt näher vor. Unterstützt werde ich dabei von vier Feldmaikäfer-Engerlingen aus Blaubeuren und eine ganze Menge Messequipment werde ich auch dabei haben. Sie finden mich am Stand von Hessen schafft Wissen/ProLOEWE (Lageplan Punkt 8) auf dem Opelgelände (Geländeplan_Hessentag)


A first time for everything

This is the 6th time that I am attending the EGU and yesterday I managed for the first time to be busy the entire day with meetings and actually not listening to any presentation or looking at any poster. That’s what scientists normally do most of the time at conferences. Listening to other scientists presenting their studies. The EGU is thematically subdivided into 22  divisions. I am usually jumping around between sessions of Atmospheric Sciences, Biogeosciences and Soil System Sciences. This is enough to bring your calendar to explode because normally one ends up with at least three different sessions running at the same time, and of course, at opposite ends of a four-storey building. However at the EGU, it does not stop there. For me it is THE PLACE for networking and there are loads of additional sessions dealing exactly just with that.

First of all, there are so-called non-public splinter meetings. You want to sit down with scientists from other universities and work on something? You can book a meeting room at the EGU. Yesterday morning we were seven people sitting together for one and a half hour working on drafts for scientific papers from a measurement campaign. These meetings can also be organized as public meetings for networking in the scientific community (e.g. “Ideas and perspectives for future research on forests and the CH4 and N2O cycles” organized by Mari Pihlatie from Helsinki) and it is also possible to contribute actively to shaping the programme of the EGU General Assembly in 2018 by joining the subdivision meetings (e.g. Subdivision SSS4: Soil Biology, Microbiology and Biodiversity). If you are a young scientist, go to these meetings! It is a great way to increase your visibility in the research community. In addition to the scientific and administrative sessions and meetings, there is also a huge exhibition with companies presenting their scientific instruments. These companies are keen on getting to know our research interests and needs to design new product lines. In the best case, it is a win-win situation for both sides. I had a meeting with a LI-COR Biosciences representative to discuss what I like about the currently availabe suit of gas analyzers and what improvements and new developments I am looking for to use in future measurement campaigns. And of course at the end of the day, I had to present my poster.


Poster presentations at the EGU can be a bit daunting and overwhelming for both the presenters and the audience. There are huge halls where you have nothing but posters. “That poster abstract sounds interesting, but do I want to walk another kilometer today to find it? Brain, are you still capable of taking in new information?”.



And thus it can happen that you have invested a lot of time in preparing a nice poster and you are at a conference with over 10.000 scientists, but maybe only two or three actually stop at your poster and maybe one asks you a question. Yesterday, I had the best poster session at the EGU ever! I love my research topic and think it is absolutely awesome and cool. What a feeling when other people come to you and have the same opinion. As it turned out, my boss did a great job in advertising my poster during her talk in the morning. A lot of people came and said “I heard this talk in the morning, can you explain me more about this and that”. One and a half hours of author’s attendance time (the time you actually should stand next to your poster to answer questions) were just flying by and I stopped counting to how many people I spoke during that time. Yes, fresh motivational boost for the upcoming work!

To finish the day, I went to listening to a talk by Pete Smith. For all of you soil scientists out there, yes, THE Pete Smith. Yesterday, he received the Philippe Duchaufour Medal for his outstanding contribution to the field of soil science and this guy is just an awesome presenter. The title of his lecture might give a hint (“Soil science is way more fun than a proper job”). You should really have a look at his abstract. And don’t get back to the first sentence of this blog post. This didn’t count as listening to a presentation. That was relaxing after work.



Goodbye solitude

Spring marks the beginning of a new field season. When I spent my days in the field measuring CH₄ fluxes between soils and the atmosphere, I am mostly all by myself. Last Thursday at my mesocosm experiment that little insect kept me company which didn’t mind being carried around with the measurement equipment.

However right now, I am in Vienna to visit one of the biggest conferences I can possibly attend in my reasearch area. The European Geosciences Union General Assembly 2017 has begun.


A full week of listening, watching, discussions, networking … over 900 sessions and more than 10000 attendees. Topics ranging literally from the Earth’s core all the way into outer space. You can even watch part of the action from home. For me, it will be the first time to present my project CH4ScarabDetect to a really large and diverse audience. If you are actually at the conference this week and interested to learn more about my project or insect CH₄ emissions in general, you can find me in poster hall X1 at board 17:30-19:00. My project supervisor, Prof. Claudia Kammann, is going to talk about rose chafers (Cetonia aurata) early in the morning in session SSS4.7.

March for Science

I study greenhouse gas fluxes between soils and the atmosphere, but I will never see my study object. I can hold a beetle larva in my hand knowing that it potentially can emit methane, but the gases stay invisible. I only ever see them indirectly as numbers on a screen or a printout. Thus it is essential for my work to be able to trust the output of analyzers, but also to trust data and publications made available by other scientists. At the same time, I have to be very critical about my own work and the work of others. All measurements have uncertainties and are prone to errors. Measurements can be interpreted in different ways. The combination of trust, critical assessment, sharing data and knowledge as well as open discussions are key elements of research integrity and the basis for advancing our knowledge. Alternative facts don’t help here. And that is why I marched for science today. And of course, to have a great time with a bunch of funny, cool and crazy people I have never met before.

Happy Birthday EU!

On 25th March 1957, 60 years ago, the Treaty of Rome was signed. That marked the beginning of what we know today as the European Union. Since then, the EU has funded many research projects, both in basic and applied research, e.g. through the Marie Sklodowska-Curie actions which fund my current project CH4ScarabDetect.

There is one thing that the EU does not want researchers to be – the infamous people in the ivory tower. The EU expects us to be mobile within Europe, to cooperate with research institutions in other countries, to connect to businesses and NGOs where applicable, and to communicate our research to the public and public stakeholders. How we accomplish this task is our own responsibility as researchers.

Today, I am in Salamanca at a conference of the Marie Curie Alumni Association. The goal of the Marie Curie Alumni Association is “promoting an active community of researchers benefiting from the European Commission’s Marie Curie programme”. Todays topics cover ‘Protecting Freedom in Science’, ‘Science and Business’, ‘International Mobility and and Mobility of Scientists’, and ‘How can MCAA help display researchers’. This conference is open for everyone and you are welcome to tune and listen to the keynote speeches in this livestream.

Workshop CH4ScarabDetect

Wo immer es möglich ist, versuche ich in meinen Forschungsprojekten Grundlagenforschung und angewandte Forschung zu verbinden. CH4ScarabDetect ist da keine Ausnahme. Daher organisiere ich im März an der Hochschule Geisenheim einen Workshop für Personen, die beruflich in der Maikäferforschung und/oder dem Maikäfermonitoring tätig sind. Ziel des Workshops ist es, das Projekt CH4ScarabDetect detailliert vorzustellen und Kooperationsmöglichkeiten mit anderen Projekten sowie staatlichen Ämtern auszuloten. Falls Sie Interesse an diesem Workshop haben, können Sie mich gerne kontaktieren.
