Garden centres can host surprisingly diverse alien floras, including species not yet recorded in the country. A survey from Hungary shows they can also act as hubs of unintentional introductions and spread, including invasive species.

Why are allopolyploids common in Batrachium, but no diploid hybrids? This puzzle is now solved: a large-scale screening uncovered a natural hybrid between diploid species, providing new insight into the early stages of polyploid evolution.

Pannonian sand grasslands persist, but their specialists fade. Species adapted to grazing and dry, nutrient-poor soils decline, while generalists and nutrient-demanding species increase, driven by succession, eutrophication and abandoned management.

🔹 Diploid hybrid finally found in Batrachium, solving a puzzle in polyploid evolution
🔹 Garden centres accumulate alien plants and act as hubs of unintentional spread

🌿 Coming soon: Preslia 97(4)! Three new papers shed light on biodiversity loss, plant evolution and overlooked drivers of plant invasions:
🔹 Pannonian sand grasslands lose specialists due to succession and eutrophication
Nine cryptic Aneura lineages confirmed in Slovenia, incl. two new for Europe. Molecular and morphological data reveal overlooked diversity in liverworts and refine species delimitation, distribution, and habitat preferences.
preslia.cz/doi/preslia.2025.589.html
In Slovenian semi-dry grasslands, over half of species are clonal. Clonal traits vary with soil conditions and community type, highlighting the need for fine-scale habitat management to preserve species and functional diversity.
preslia.cz/doi/preslia.2025.567.html
Spatially uneven sampling of species occurrences can mislead biodiversity research. A new study of Czech flora by Klímová et al. reveals how different methods mitigate the distortions in the patterns of species richness.

1,615 alien plant taxa now listed for Austria, +49% in 20 years! Mostly garden escapes or stowaways. The updated checklist includes origins, habitats, impacts, and is a key tool for invasion science and policy.

🔹 Clonal traits and persistence strategies vary with community composition in Slovenian semi-dry calcareous grasslands
🔹 9 cryptic lineages of Aneura revealed in Slovenia, including 2 new to Europe, #liverworts
The full issue will be online soon.

🌿 Preslia 97(3) is almost here, bringing new insights into plant invasions, diversity and traits in Europe:
🔹 1615 neophyte taxa in Austria, nearly half since 2000, mostly garden escapes
🔹 Geological heterogeneity and land use history shape spatial patterns of species richness across the Czech flora
Field surveys across Poland reveal that Neotinea ustulata survives mainly in dry, open grasslands on shallow soils. Habitat extremity, not conservation effort, emerges as the key to persistence of this rapidly declining orchid.

A comprehensive survey reveals 61 bramble species in the Bohemian Forest, including 30 new regional records and 5 species new to science. The study highlights remarkable regional endemism and the role of human-made habitats in species distribution.
Lakes in the Alps hide a surprising story: Alpine populations are genetically identical to the Nordic Ranunculus confervoides, yet show unexpected haplotype diversity and novel hybrids, revealing a complex evolutionary history.
preslia.cz/doi/preslia.2025.191.html
🔹 What drives plant succession? Traits like life form and seed mass predict when species peak after disturbance
🔹 Rubus species mapped in the Bohemian Forest, including five new to science and 30 newly recorded

🌿 Coming soon: Preslia 97(2)! Highlights include:
🔹 Unexpected genetic richness and hybridization in aquatic Ranunculus reveals hidden diversity in Alpine lakes
🔹 Harsh habitats help: survival of Neotinea ustulata in Poland tied to dry, extreme grassland conditions
Pulsatilla grandis is vanishing! A 19-year monitoring study in Czechia revealed a 20% population loss and a 25% decline in flowering individuals. Effective habitat management is crucial to reverse this trend and protect other endangered dry grassland species.
Decline of the most beautiful Czech orchid, and spatial and temporal dynamics of 102 other species in another instalment of the series on the distribution of plants in the Czech Republic.

Despite declining SO₂ emissions, acidifying air pollution still impacts epiphytic bryophyte communities in central Europe. Ash trees with higher bark pH hosted richer, more sensitive assemblages but were as affected by SO₂ as oaks.

Cytogeography of almost 4800 individuals of aggressive invasive alien Solidago canadensis and S. gigantea in the Western Carpathians and adjacent regions. New cytotypes for invaded range, their probable origin and importance of correct taxonomic identification.

Enigmatic Stipa epilosa from the Alps underwent morphometric, AFLP and microhabitat analyses. No genetic or ecological differences between S. eriocaulis and S. epilosa were found, and morphological variation formed a continuum.

An international team led by our scientists discovered 43 new species of lichens for the Czech Republic, 12 completely new to science and 2 new genera. Combining environmental DNA data and taxonomic surveys accelerates the discovery of new species. More @preslia.cz www.preslia.cz/article/pdf?...
Expansive plants are native but behave similarly to alien invasive plants and can also have negative impacts. The first catalogue of the expansive flora of the Czech Republic includes 126 taxa, with the regions and habitats, where they spread. preslia.cz/doi/preslia.2024.299.html
Our new paper led by Irena Axmanová in @preslia.cz focuses on "expansive plant species", i.e. native plants that are increasing their abundance in the landscape or dominance in local communities. See more info in the thread by @krystofchytry.bsky.social

Urtica kioviensis is a rare species of river basins. Hybridization with the widespread U. dioica was confirmed at six sites in central Europe. It affects genetic integrity of U. kioviensis and can pose a risk to small populations of this species. preslia.cz/doi/preslia.2024.329.html

Gravel bars in the Elbe River host specific vegetation, incl. alien and endangered plants. The duration of flooding determines the vegetation, but not the seed bank composition. The seed bank acts as a reservoir, allowing regeneration after disturbance. preslia.cz/doi/preslia....
