Common Mediterranean plants I tried to learn about on my first journey to Spain. Finishing this submission to the university herbarium brings back memories of the places we visited, from north to south across the Iberian Peninsula.

Rare allergenic weeds I documented 20 years ago, back when these Prague sites still existed—Karlínská náplavka, Bubny railway station. Most are gone now. These specimens live on in the Charles University Herbarium or as pictures at pladias.cz / www.botanickafotogalerie.cz

Our 1:1100 3D pollen collection now includes about 80 models @olijwilson.bsky.social @cubioimaginghub.bsky.social. They’re made from transparent gel for softness, plastic filament for affordability, or powder. The transport box is getting small!

Plant Fascination Day featured pollen demonstration by 3D models @olijwilson.bsky.social @cubioimaginghub.bsky.social and pollen stamps, fascinated visitors and their artworks

I found nice tufa deposit during my Easter floristic hunt (Primula farinosa, Narcissus bulbocodium) in Sierra de Zafrilla (Cuenca). Pollen will be preserved? How old will be the bottom sample?

Excellent results from our students in the Karyology and Palynology practicum (with Tomáš Urfus) @sciencecharles.bsky.social Hands-on methods: flow cytometry, acetolysis… How strong is the relationship between pollen size and genome size? Flowering samples from @botanickazahradauk.bsky.social

Some exciting news! Our PhD candidate @kijumil.bsky.social just submitted his paper about the first relative pollen productivity estimates (RPPs) in the Iberian Peninsula. 🥬🌿 But, what exactly are RPPs and why are they important in palaeoecology ? Follow through the post to find out! ⬇️

The Lysimachia vulgaris pollen illustration originally drawn for Fig. 2 in our Journal of Ecology paper is now available as a stamp! besjournals.onlinelibrary.wiley.com/doi/full/10....

Most of our department joined ice-breaker of PalaeOpen 2025 meeting at the Botanical Garden of Charles University in Prague, including members of the organizing team and our new colleague Vojtěch Abraham (bottom right in the photo). A great evening with the international paleoscience community!

Excavation at the Quaternary Refugium Zli Dol (Galičica NP) We're searching for fossil evidence of relict plant populations—and during the excavation, we uncovered Bronze Age pottery in the trench! A fantastic collaboration with the Archaeological Museum of Skopje and the Czech Geological Survey.

I hope to learn a lot in my new role as Review Editor for Frontiers in Ecology and Evolution - Palaeoecology, which I have just accepted. New commitments led me to join another social network. loop.frontiersin.org/people/29722...

Accommodation has been booked for the summer fieldwork in Ohrid 🇲🇰. In addition to coring, this year we will be excavating ⛏️ locations suspected to be Quaternary refugia, due to the presence of various relict taxa, eg Ramonda, Aesculus.

Floods as a geological force-see the missing bark. Will we find the Permo-Triassic boundary at the base of Buntsandstein? How old are the pine cones under the floodplain deposits or the black-red mudstones? Exploring the clearances around Arroyo del Regajo (E Spain) after flood of October 29, 2024.

Hi there, I am using bsky and also mastodon to see who is where
