Milan Chytrý @milanchytry.bsky.social · 30/09/2026I started the Czech Vegetation Database 30 years ago. Now, my colleagues and I have prepared the entire database (> 17,000 vegetation plots) as an open dataset. Our new Preslia article describes the database, its history, current state, published datasets & related resources doi.org/10.23855/pre... 0218
Milan Chytrý @milanchytry.bsky.social · 06/09/2026We sampled a dry grassland in Armenia, which contained 90 and 104 vascular plant species in plots of 10 m² and 25 m², respectively. These counts are higher than those recorded in any European grassland so far, except for the Carpathian region and steppes near Kursk. www.tuexenia.de/publications... 1359
Milan Chytrý @milanchytry.bsky.social · 27/08/2026In this new article, I trace the history of European vegetation-plot databases, from the handwritten relevés stored in the filing cabinets of phytosociologists to the millions of vegetation plots now held in the European Vegetation Archive. www.sci.muni.cz/botany/chytr... 092
Milan Chytrý @milanchytry.bsky.social · 26/08/2026Can we trust? Yes, we can trust estimates of species turnover, but estimates of changes in species richness are less reliable. Our new article in the Journal of Ecology: doi.org/10.1111/1365... @journalofecology.bsky.social @iavs5.bsky.social 1196
Milan Chytrý @milanchytry.bsky.social · 25/08/2026We have prepared a major update (version 2) of EVA-MAP - www.evamap.eu - an interactive online application for visualizing vegetation plots included in the European Vegetation Archive and ReSurveyEurope databases, with many new visualization options. 044

Milan Chytrý @milanchytry.bsky.social · 11/04/2026Our new article in Science Advances, led by Gabriele Midolo, identifies the main factors driving changes in the species composition of plant communities across Europe: eutrophication, denser, more productive vegetation, and drying of wetlands. doi.org/10.1126/scia... 14011
Milan Chytrý @milanchytry.bsky.social · 28/03/2026Distylous flowers in Primula veris (prvosenka jarní). The flower on the left has a short style with anthers above the stigma, while the flower on the right has a long style with anthers below the stigma. Both forms occur within the same population, and distyly prevents self-pollination. 160
Milan Chytrý @milanchytry.bsky.social · 22/03/2026Mixed populations of two early-spring violets of southern European origin are now flowering in the Czech lowlands.

Milan Chytrý @milanchytry.bsky.social · 10/11/2025Our new paper in Ecology Letters, led by Jan Divíšek, shows that non-invasive alien plant species that successfully establish within local plant communities tend to resemble the resident native species. In contrast, invasive alien species usually differ from native plants. doi.org/10.1111/ele.... 18130

Milan Chytrý @milanchytry.bsky.social · 02/11/2025In our new article led by Gabriele Midolo, published in Ecology Letters, we show that plant species richness in European plant communities generally decreased between the 1960s and 1980s. However, since the 1990s, this trend seems to have stopped or even reversed. dx.doi.org/10.1111/ele.... 14520

Milan Chytrý @milanchytry.bsky.social · 12/08/2025🌱 In our new article led by Luigi Cao Pinna, we show that alien plants in the Mediterranean often shift their niches, i.e. either do not fill or expand their occupied climatic space compared to the native range, partly depending on their traits. 🔗 fulltext: doi.org/10.1111/gcb.... 073
Milan Chytrý @milanchytry.bsky.social · 27/07/2025Two subalpine pines from the Rocky Mountains have contrasting seed regeneration strategies. Pinus contorta is serotinous: the seeds remain in the cones for several years. Forest fire releases them, they fall to the ground, and a massive regeneration of even-aged pine forest stands begins. 131
Milan Chytrý @milanchytry.bsky.social · 27/07/2025This is the result of the largest fire ever recorded in Colorado, which lasted for 4 months (Aug-Dec 2020) and burned 840 km2 (!) of forest. Like in other large forest fires, the ultimate cause was the suppression of small fires for several decades, which led to a significant accumulation of fuel. 152
Milan Chytrý @milanchytry.bsky.social · 26/07/2025Many natural habitats in the Rocky Mountain foothills are heavily invaded by two Eurasian grasses: Bromus inermis and Agropyron cristatum agg. Both species were intentionally sown to prevent wind erosion after the conversion of prairie to arable land and subsequent massive dust storms in the 1930s. 020
