Hidden diversity of Ranunculus sect. Batrachium in the Pannonian Basin

Vojtěch Dolejšek, Attila Mesterházy, Magdalena Lučanová, Viktorie Brožová et autres

Ranunculus sect. Batrachium is one of the most taxonomically challenging groups of aquatic plants. The main factors contributing to this complexity include morphological reduction, phenotypic plasticity, polyploidy and hybridization. In this study, Batrachium diversity in the Pannonian Basin was investigated for the …

Identifying the richness and evolutionary relationships of Ranunculus sect. Batrachium in its diversity centre in south-western Europe

Jan Prančl, Petr Koutecký, Magdalena Lučanová, Michaela Nagy Nejedlá et autres

Aquatic plants are generally attributed to have larger ranges than their terrestrial counterparts, but this knowledge is often hindered by insufficient exploration of their diversity. To fill this gap, we investigated the taxonomically extremely challenging aquatic plant group Ranunculus sect. Batrachium in …

Striking diversity in Alpine lakes

Petr Koutecký, Jan Prančl, Magdalena Lučanová, Viktorie Brožová et autres

The Ranunculus trichophyllus group has a complex evolutionary history and remains taxonomically unresolved. In central Europe outside the Alps, two tetraploid cytotypes distinguished as R. trichophyllus A and B have been recognized in previous studies. Another ecologically specialized taxon, R. confervoides (R. …

Ecological and evolutionary consequences of ploidy-driven trait variation: insights from Saxifraga oppositifolia L.

Pernille Bronken Eidesen, Anne K. Brysting, Kathleen Rani Hagen, Simen Salomonsen Hjelle et autres

The ecological and evolutionary consequences of ploidy-driven trait variation, particularly for autopolyploids, remain poorly understood. Saxifraga oppositifolia L. (purple saxifrage) is a highly successful arctic-alpine plant species with significant genetic and phenotypic variation potentially related to autopolyploidy. Over the past decade, we …

From everywhere all at once: Several colonization routes available to Svalbard in the early Holocene

Viktorie Brožová, Johannes S. Bolstad, Alexey P. Seregin, Pernille Bronken Eidesen

Abstract For many arctic species, the spatial (re‐)colonization patterns after the last Pleistocene glaciation have been described. However, the temporal aspects of their colonization are largely missing. Did one route prevail early, while another was more important later? The high Arctic archipelago …

Plant apomixis is rare in Himalayan high-alpine flora

Viktorie Brožová, Petr Koutecký, Jiří Doležal

Gametophytic apomixis is a way of asexual plant reproduction by seeds. It should be advantageous under stressful high altitude or latitude environment where short growing seasons, low temperatures, low pollinator activity or unstable weather may hamper sexual reproduction. However, this hypothesis remains …
