Paleoenvironmental Research Lab at the University of Gdansk is looking for a PhD student interested in #paleolimnology #lakes #sediments #geochronology #geology #sedimentology #geochemistry #phdchat

Project: Varved sediments have been established as one of the most prominent environmental archives. Lake Synevyr is the first site in the Eastern Carpathians where varved sediments were discovered, providing the basis for completely new reconstructions of the Holocene environmental changes in this region. With our project we address the following research questions: What was the dynamics of climate change / human impact in the region during the transition from a nature-dominated to a human-dominated environment? Is the most recent time unusual within the Holocene? We aim to (1) reconstruct local vegetation changes, soil erosion and lake productivity since lake initiation to the present, and (2) evaluate the interactions between climate variability / human activity, and their impact on the lake environment.
Contact: The project is led by Prof. Wojciech Tylmann form Paleoenvironmental Research Laboratory, Department of Geomorphology and Quaternary Geology. Candidates are requested to send (in one PDF file!) their CV including scientific achievements, motivation letter, references from the supervisor of their MSc thesis or immediate superior, and consent to the processing of personal data to the following email address: wojciech.tylmann@ug.edu.pl. The final deadline for submissions is July 25th at 3:00 pm, and the competition results will be announced by July 31th, 2025. Any questions regarding both the scientific scope of the project and the organizational-financial aspects can be directed to the same email address (wojciech.tylmann@ug.edu.pl).

A lucky find- Lesquereusia in the middle of division! When finished, it will fill the second test (shell) that it built. Local bog sample. #testateamoebae #protistsonsky

Recently, we described a "new" species of amoeba. It's just been found it again, 700 km away. I suspect it's common in eastern N.A., but not noticed until it had a name. One reason to do taxonomy: describing a thing makes it visible! www.inaturalist.org/observations... #taxonomy #systematics

🚨New preprint out! We show that Arcella spp., a shell-bearing amoeba, controls the abundance of the filamentous bacterium Ca. Microthrix parvicella, the main culprit behind sludge bulking in wastewater treatment plants. Interested in applicability of protists? Read along! #protistsonsky #microsky 🧵👇

First field trip this year, checking and maintaining equipment and reading data. Unfortunately, we start this year with worse moisture conditions than last year. If last year at the end of the summer on some sites the ground water dropped to -80 cm, I don't know how it will be this year...

Avert your eyes if you have "trypophobia"! Here are some close views of the beautiful organic "glue" the amoeba Difflugia microclaviformis uses to cement together bits of quartz and diatoms, to build its shell. #ProtistsonSky #amoebae #peatlands #NatureisLit

A perfect little thing, crafted by a cunning amoeboid. This shell was collected in a calcareous fen near Winnipeg, Canada. It's the handiwork (pseudopodiwork?) of the cercozoan amoeba Scutiglypha scutigera (=Euglypha scutigera). #ProtistsOnSky #TestateAmoebae #peatland

The shelled amoeba Zivkovicia compressa, divided internally by a central pillar and a thin-walled "diaphragm" with two round openings. Maybe for defense against parasitic rotifers and other micro-villains? Last pic shows its rather fancy organic cement. #ProtistsOnSky #Protists #Amoebae

I’m so excited! 🥳 Our new article just came out, describing a brand-new genus and four new species of #testate #amoebae from #Mongolia! #protists 🔬🌍 It was such a pleasure to collaborate with Ferry Siemensma – truly an inspiring scientist! 🙃 👉 authors.elsevier.com/a/1kP5K3K1I1...

Back in the lab, and the Minions are already causing chaos – looks like the old year is heading for a ‘productive’ finish 😅 #charcoal #paleoecology

Not a fish or a dragon scale, but a single cell of a #protistsonsky. This rhizarian testate amoeba creates perfect tiny glass scales to build it's shell. From a peat bog. #protistaday.

With my twitter account deleted, I am going to start re-sharing some of my favorite images. While I'm working on specific scientific questions and hypotheses, I also like to use the tools at hand to simply explore the microscopic world. Here is the same testate amoeba in light, fluorescence, and SEM

Usually, I don't pay much attention to diatoms and chrysophytes, but when an amoeba glues a bunch of them together to make its shell, suddenly I can't stop staring. Here are two shells of Difflugia globulosa, collected in Chisasibi, on the coast of James Bay. #ProtistsOnSky
