A new insight on the genus Pteridium (Dennstaedtiaceae) in Europe based on a revision in the flora of Slovakia
(Springer Science+Business Media : New York, 2024) Peregrym, Mykyta; Turisová, Ingrid; Turis, Peter
Background The genus Pteridium Gled. ex Scop. was thought to be monotypic with the cosmopolitan species P. aquilinum (L.) Kuhn. for many years. However, morphological variations among these plants in different regions have been noted since the 1940’s, leading to the description of new taxa later. Molecular investigations, while not resolving all taxonomical questions within the genus, have highlighted its rich genetic diversity globally, confirming the status of several previously described species and subspecies. This wealth of data has prompted revisions of the Pteridium genus in regional floras, with Northern Eurasia serving as a central arena for such studies in the last 30 years. Recent data suggest that the European flora comprises a single species, P. aquilinum, with two subspecies, P. a. subsp. aquilinum and P. a. subsp. pinetorum (C.N. Page & R.R. Mill) J.A. Thomson. However, their distribution within the continent remains unclear. Therefore, this study aims to elucidate the representation and distribution of Pteridium taxa in Slovakia with an attempt to describe natural ranges of P. aquilinum subspecies based on herbarium materials and citizen science data within Europe for a whole. Results It is confirmed that the genus Pteridium is represented by the single species with two mentioned subspecies in the flora of Europe, as well as in the flora of Slovakia. The distribution of these subspecies is mapped in the country. Additionally, we discuss the ranges of these subspecies for a whole, and we evidence the growth of P. aquilinum subsp. pinetorum within the Netherlands, Czechia, Austria, Hungary and Romania for the first time. Also, two new combinations of taxa from the Asian part of Russia are offered. Conclusion Our study is a significant contribution in the present knowledge about the distribution and taxonomy of P. aquilinum, however it also shows that many questions concerning this taxon and its infraspecific taxa remain open. Additional field investigations and herbarium processing should be carried out for detailed explorations of biological and ecological peculiarities of the mentioned subspecies, and for the clear understanding of their regional distribution. Such explorations also might become a basis for new syntaxonomic revisions.
Chorologické doplnky k cievnatým rastlinám Národného parku Nízke Tatry
(Belianum. Vydavateľstvo Univerzity Mateja Bela v Banskej Bystrici, 2024) Turis, Peter
Floristický výskum oblasti zahŕňajúcej Národný park Nízke Tatry aj s ochranným pásmom má dlhodobú históriu a jeho výsledky boli uverejnené v mnohých prácach (cf. Turis 2004). Prehľad taxónov celého územia však doposiaľ nie je vypracovaný a tento zoznam sa neustále rozširuje nielen v dôsledku detailnejšieho prieskumu regiónu, ale aj vďaka taxonomickému bádaniu botanikov, zavliekaniu nových druhov, alebo migrácii rastlinstva. Početné publikácie sú venované aj upresňovaniu rozšírenia jednotlivých taxónov v území. Rovnako aj predložená práca je zameraná na doplnenie chorologických údajov z uvedenej oblasti. Jej ďalším cieľom je na základe aktuálne zistenej distribúcie rastlín identifikovať floristicky najcennejšie časti sledovaného územia a vytvoriť prehľad najvýznamnejších rastlinných druhov.
Environmental heterogeneity structures root-associated fungal communities in Daphne arbuscula (Thymelaeaceae), a shrub adapted to extreme rocky habitats
(John Wiley & Sons : Hoboken, 2024) Gajdošová, Zuzana; Caboň, Miroslav; Kolaříková, Zuzana; Sudová, Radka; Rydlová, Jana; Turisová, Ingrid; Turis, Peter; Kučera, Jaromír; Slovák, Marek
Rocky habitats, globally distributed ecosystems, harbour diverse biota, including numerous endemic and endangered species. Vascular plants thriving in these environments face challenging abiotic conditions, requiring diverse morphological and physiological adaptations. Their engagement with the surrounding microbiomes is, however, equally vital for their adaptation, fitness, and long-term survival. Nevertheless, there remains a lack of understanding surrounding this complex interplay within this fascinating biotic ecosystem. Using microscopic observations and metabarcoding analyses, we examined the fungal abundance and diversity in the root system of the rock-dwelling West Carpathian endemic shrub, Daphne arbuscula (Thymelaeaceae). We explored the diversification of root-associated fungal communities in relation to microclimatic variations across the studied sites. We revealed extensive colonization of the Daphne roots by diverse taxonomic fungal groups attributed to different ecological guilds, predominantly plant pathogens, dark septate endophytes (DSE), and arbuscular mycorrhizal fungi (AMF). Notably, differences in taxonomic composition and ecological guilds emerged between colder and warmer microenvironments. Apart from omnipresent AMF, warmer sites exhibited a prevalence of plant pathogens, while colder sites were characterized by a dominance of DSE. This mycobiome diversification, most likely triggered by the environment, suggests that D. arbuscula populations in warmer areas may be more vulnerable to fungal diseases, particularly in the context of global climate change.
Needle structure in three Juniperus taxa indigenous to Slovakia
(Multidisciplinary Digital Publishing Institute : Basel, 2025) Galgóci, Martin; Kormuťák, Andrej; Gömöry, Dušan; Klobučník, Miroslav; Turis, Peter; Mistríková, Veronika; Boleček, Peter
Needle structure was analyzed in three Juniperus communis taxa from different localities in central Slovakia. The main aim was to test the hybrid origin hypothesis of J. communis nothovar. intermedia (Schur) Nyman, defined as a cross between J. communis L. ssp. communis and J. communis ssp. nana (Hook.) Syme. While DNA-based analyses remain the most reliable tool for inferring evolutionary history, comparative needle morphology can provide complementary evidence, including diagnostic traits for taxonomic delimitation. In this study, we evaluated three morphometric and sixteen anatomical needle traits, measured via microscopy in ten shrubs per taxon. The analyses indicated that most traits in nothovar. intermedia matched one of the parents, with only two traits proving strongly diagnostic, separating all three taxa: needle length, which showed an intermediate mean phenotype in nothovar. intermedia (R2 = 0.824, p = 0.011; between parents), and vascular bundle height, which displayed a transgressive pattern (R2 = 0.552, p = 0.031; between parents). Although the diagnostic value of individual traits for hybrid detection was generally weak, a phylogenetic network analysis based on six diagnostic traits that separated individuals of the parental taxa provided evidence for reticulate evolution. These results support the hybrid origin of J. communis nothovar. intermedia and highlight needle traits with potential value for distinguishing ssp. communis and ssp. nana in natural populations, which may assist in taxonomic delimitation and inform future conservation assessments.

Tri dekády po výseve rastlín v Chránenom areáli Jakub pri Banskej Bystrici - čo sa zmenilo?
(Slovenská botanická spoločnosť pri SAV : Bratislava, 2025) Turis, Peter
After more than three decades since the deliberate introduction of seeds of 35 locally non-native plant taxa into the territory of Jakub Protected Site, six hemicryptophytes still persist, while representatives of other life forms have either failed to establish or have become extinct. Thriving populations with dozens of flowering individuals have developed for Linum perenne and L. tenuifolium. Other established species, Aconitum moldavicum and Helleborus niger, occur in lower abundance and remain mostly sterile. Micro-populations of Dictamnus albus and Hepatica nobilis survive with only a minimal number of individuals and are on the brink of extinction. The sowing of seeds of a species from the genus Stipa at the site is uncertain. It was most likely S. pulcherrima, whose population is expanding, while two additional feather-grass species appear to have colonized the area spontaneously.
Understanding early stages of speciation: Allopatric divergence, introgression and chromosomal dynamics in the Erysimum odoratum species complex
(Academic Press : San Diego, 2026) Bačák, Richard; Šlenker, Marek; Šingliarová, Barbora; Mandáková, Terezie; Skokanová, Katarína; Turisová, Ingrid; Turis, Peter; Smatanová, Janka; Zozomová-Lihová, Judita
Accurate species delimitation is essential for understanding biodiversity and evolutionary processes, yet it remains challenging in taxonomically complex groups shaped by recent divergence and reticulate evolution. Nevertheless, such groups offer unique insights into the earliest stages of speciation and its driving forces. The genus Erysimum (Brassicaceae), notable for its karyological diversity and high endemism, represents an excellent model for such studies. Here, we investigated the E. odoratum complex, encompassing up to 10 recognized species in the Carpathians and western Balkans, to test its monophyletic origin, clarify species boundaries and elucidate the main drivers of diversification. We combined cytotype screening (chromosome counting and flow cytometry), morphometric analysis, and two high-throughput sequencing methods: RADseq, to resolve phylogenetic relationships as well as to detect fine-scale genetic structure and introgression; and target enrichment (Hyb-Seq), to elucidate polyploid origins. Our results demonstrate that the studied complex is polyphyletic, and we focused on the lineage comprising E. odoratum s.str. and Carpathian species. Phylogenomic data from the Carpathians contradict traditional taxonomy, which recognized up to four diploid endemics, and instead support a single species, E. witmannii with geographically structured genetic variation. Within E. odoratum s.str., we identified multiple polyploid cytotypes resulting from independent auto- and allopolyploidization events, although disentangling parental subgenomes, ancestral polymorphisms, and introgression remains difficult. We propose that diversification in this species complex has been driven by a combination of allopatric divergence and reticulate evolution (involving both introgression and allopolyploidy), further shaped by chromosomal dynamics such as dysploidy.
Unravelling some factors affecting sexual reproduction in rock-specialist shrub: Insight from an endemic Daphne arbuscula (Thymelaeaceae)
(Public Library of Science : San Francisco, 2024) Gajdošová, Zuzana; Šlenker, Marek; Svitok, Marek; Šrámková, Gabriela; Blanár, Drahoš; Cetlová, Veronika; Kučera, Jaromír; Turisová, Ingrid; Turis, Peter; Slovák, Marek
The role of endemic species in global biodiversity is pivotal, and understanding their biology and ecology is imperative for their fitness and long-term survival, particularly in the face of ongoing climatic oscillations. Our primary goal was to investigate the sexual reproduction level of the endangered Western Carpathian endemic Daphne arbuscula (Thymelaeaceae), which inhabits extreme rocky habitats, and to comprehend the influence of specific factors on its reproductive success. We conducted the research across four populations, varying in size and environmental conditions. Over two years, we monitored flower and fruit production, analyzed genetic variability within and among populations, and studied pollination mechanisms. Daphne arbuscula proved to be strictly self-incompatible, with significant variations in flower and fruit production among populations and seasons. The average fruit production percentage consistently remained below 50% across populations, indicating challenges in sexual reproduction. Cold and harsh weather during the reproductive phase had a substantial negative impact on sexual reproduction efficacy, leading to decreased fruit production. Nevertheless, several individuals in sheltered microhabitats displayed significantly higher fruit production, ranging from 60% to 83%, emphasizing the critical role of microhabitat heterogeneity in sustaining sexual reproduction in this species. We found no pronounced differences in genetic diversity within or among populations, suggesting that genetic factors may not critically influence the reproductive success of this endemic species. The implications of our findings might be of paramount importance for the long-term survival of D. arbuscula and offer valuable insights for the development of effective conservation strategies for this species.
