Happy to share our new paper in @JPhycology on Synurales from Florida - adding a fresh piece to the puzzle of silica-ornamented algal diversity and evolution! One of the newly described species even made it to the cover of the issue.😊 https://t.co/O2nTfOZHvq

In this paper, we show that photobiont diversity increases as lichens age. Interestingly, as the thallus grows, autosporine algae become more prevalent at the expense of zoosporine algae, likely because the latter play a key role in lichen establishment. https://t.co/nHwdCAs0bf

Imagine a forest where every tree vanishes overnight from a gust of wind. Or a meadow where all small birds disappear due to a hawk surge. That’s the scale of change we saw - only it’s underwater, invisible, and microbial. 🙂

Just published! Our new study reveals how phytoplankton communities can shift dramatically within mere days - driven by grazers like Cladocera and environmental factors such as silica concentration and wind speed. https://t.co/PaL0QcofrV

Huge congratulations to Veronika Kantnerová for winning the Best Student Presentation Award at the #ICOP2025 Congress in Seoul, Korea!❤️🏆I’m incredibly proud of her success. You can check out her award-winning poster here if you're curious: https://t.co/YFxeVZ8Guk

Very happy to be involved in this very interesting study on lichen symbiosis.

We just described a novel chrysophyte genus Globulochrysis. It produces teardrop-shaped zoospores and big spherical cell packets🙃. https://t.co/1UQhswKJJu

We are happy to share our review paper summarizing the diversity of green algal lichen symbionts and their free-living occurrences: https://t.co/1VE4KXbGcf

#Paper_Alert! Did you ever wonder why there is such a large morphological diversity in #shell-bearing #amoebae and what is the #function of shells anyway? It was long assumed shells are for #defense, well let me try to convince you that their purpose is #attack! A thread🧵👇

In summary, we show that diversification of protist species can be very rapid. Accordingly, the vast biodiversity of protists and other microorganisms can be explained by rapid ecological speciation despite their widespread dispersal.

Genetically differentiated clusters also differed in temperature growth dynamics and DNA content, suggesting the presence of local adaptation.

We detected three geographically and ecologically distinct clusters of populations and two admixed clusters representing contact zones. Habitat and climate were the major drivers of diversification on the regional scale, while geography played a role over longer distances.

We investigated the population structure in a colonial chrysophyte species Synura petersenii to identify drivers of population differentiation and specition over a short period of time (10,000–150,000 years).

Happy to share our recent publication on the rapid diversification and speciation of a free living protist. https://t.co/7MbzUE4o6D

Finally, in the third paper we resolved the phylogenetic position of the silica scale-forming genus Spiniferomonas, showing that it represents a sister lineage to the genus Chrysosphaerella. https://t.co/JOtFl78UWL

By analyzing the extent of scale deformation, we found that while in Synura the ribs play a key role in the stability of the scale, in Mallomonas they have a negligible effect on stability and apparently play a different function. https://t.co/OfpIt58hdJ

In the second paper, we tested the mechanical resistance of microscopic silica scales equipped by parallel–arranged ribs. For genera Synura and Mallomonas, we created several models differing by the number and orientation of ribs.

In the first paper, we evaluated a unique example of cryptic diversity in a freshwater protist, Synura sphagnicola. We also synonymized the class Synurophyceae with Chrysophyceae, and reported the discovery of a new, yet unknown red pigment. https://t.co/irda115bLy

We are happy to announce the release of the Fottea special issue devoted to Chrysophytes research! https://t.co/MAZjLsrCtU Three papers that we contributed are briefly described below.

Congratulations to Zuzana Skvorova on receiving the Bohuslav Fott Award for the best 2022 student publication. In her paper, Zuzana showed that associations between lichen symbiotic partners are driven by partners preferenes for soil chemistry and climate. https://t.co/XcUW9n41U5
