Very proud of Antonia Klatt, who did an excellent job defending her PhD thesis yesterday. Toni is the first PhD from our Uni Basel Organic Geochemistry group, and has been a joy to work with over the past four years. Can't wait to see what she accomplishes next!

In a central European context, correcting plant wax d2H values with a simple index based on the relative abundance of different n-alkanes seems to do the trick, allowing us to get reasonable estimates of past precipitation isotopes during times with big ecological changes

How can we best correct for vegetation changes when reconstructing precipitation hydrogen isotopes from plant waxes? @ricardoansantos.bsky.social answers this question with sediments from Rotsee, our favorite little lake

I’m delighted to share our new paper on sedimentary plant waxes and their use to assess past hydroclimate since the Younger Dryas in Central Europe:🍃👨‍🔬🌦️

Our paper about VOC fluxes from leaf litter following rewetting is now published in JGR-Biogeosciences. Led by Lia Crocker, making use of leaf litter from the B2 WALD drought

Finally out: my #TEDtalk on our work on #climatechange #impact on #forests🌲🌳 and #B2WALD amd #ECOSENSE @nemiahladd.bsky.social @laurameredith.bsky.social @ecosense-sfb-1537.bsky.social Happy to share: share.google/Ag6muXOslSln...

I'm looking for a driven PhD student to join us at @au.dk and to both generate new paleoclimate data in the lab and work on computational problems to understand climate relationships across timescales.

Get in touch if you'd like to hear more, and apply by Nov 1!

Universität Basel: PhD Position in Organic Geochemistry and Soil Microbiology The Department of Environmental Sciences, University of Basel invites applications for a PhD position in the field of organic geochemistry and soil microbiology (https://duw.unibas.ch/en/research-grou...

I have a new PhD position open in my research group, for a project studying how soil microbial communities, metabolism, and carbon use efficiency respond to drought 🧪. The application window closes on April 30, full instructions and more information here: jobs.unibas.ch/offene-stell...

We got the chance to sample Rotsee every two weeks in 2019 thanks to a campaign led by @cindydejonge.bsky.social and benefited from collaboration with researchers at Eawag (Marta Reyes, Nathalie Dubois, Carsten Schubert) and Basel (Dan Nelson)

This is the first publication led by a PhD student from my research group in Basel. It has been really fun working with Toni over the past three years -- stay tuned for some more cool results, including applications to sediment cores, that she currently has in the works

Can we use H isotope offsets among lipids as proxies of algal community composition? New paper led by Antonia Klatt shows that changes with community throughout a year in Rotsee aren similar results from cultures and indicate minimal influence from heterotrophs: doi.org/10.1016/j.gc...

Back in 2019 we screened an obscure lineage of bacteria for a side project and noticed something quite unusual. A quinone, used in cellular electron transport, that looked similar to the type used by plants and algae to perform photosynthesis.

To all prospective PhD students with an interest in organic geochemistry and paleoclimate - we have three competition-funded PhDs on offer this year via our DTP (deadline 8th Jan). More details below!

Achieving climate targets is primarily limited by politics, institutions and humans, not technology, solutions or money.

It's values and priorities, about who we are. (1/7)

Sedimentary biomarkers of human presence and taro cultivation reveal early horticulture in Remote Oceania Communications Earth & Environment - Human settlement and horticulture began in Vanuatu at least 2800 years ago during a wet climatic period, according to an analysis of sedimentary biomarkers...

When did people first inhabit islands in Remote Oceania, and how did they feed themselves when they arrived? Our new study, led by Giorgia Camperio, constrains the timing of human arrival on Efate, Vanuatu, and demonstrates that the first inhabitants cultivated taro: rdcu.be/dZmgY

Screenshot of the following text: Lipid biomarkers: novel applications, calibrations and tools for environmental studies Lipid biomarkers are valuable tools for reconstructing a variety of environmental processes in modern and (geological) past settings. We seek studies that develop new lipid biomarkers and methods for applying biomarkers to modern settings and the geologic past to reconstruct environmental parameters such as temperature, precipitation, biogeochemical cycles, anthropogenic activities, and vegetation. These can be studies on the biosynthesis and phylogeny of source organisms, transport and diagenesis, calibrations to environmental parameters, proxy interpretation and applications to reconstruct past environmental conditions.
