Eksploracje prowadzono w czterech obszarach, po dwa w Tatrach Wysokich i Zachodnich. Łącznie zinwentaryzowano 82 gatunki wątrobowców. Największą bioróżnorodność odnotowano w Tatrach Wysokich, w Waksmundzkim Żlebie i na północnych stokach Mięguszowieckich Szczytów. Po raz pierwszy w polskiej części Tatr Wysokich odnaleziono dwie rośliny – Jungermannia polaris i Scapania calcicola. Dla trzech gatunków ustalono nowe maksima wysokościowe w skali całego masywu tatrzańskiego. Są to: Bazzania flaccida (2201 m n.p.m.), Mesoptychia heterocolpos (2201 m n.p.m.) oraz Solenostoma confertissimum (2254 m n.p.m.). Jeden arktyczno-alpejski gatunek, Scapania cuspiduligera, odnotowano na nowym minimum wysokościowym (1027 m n.p.m.). W prezentowanym wykazie 11 wątrobowców znajduje się na polskiej, czerwonej liście gatunk...

The newly sequenced plastomes of Conocephalum, Riccia and Sphaerocarpos species revealed an increase of simple sequence repeats during the diversification of complex thalloid liverwort lineage. The presence of long TA motifs forced applying the long-read nanopore sequencing method for proper and dependable plastome assembly, since the length of dinucleotide repeats overcome the length of Illumina short reads. The accumulation of SSRs (simple sequence repeats) enabled the expansion of inverted repeats by the incorporation of rps12 and rps7 genes, which were part of large single copy (LSC) regions in the previously sequenced plastomes. The expansion of inverted repeat (IR) at the genus level is reported for the first time for non-flowering plants. Moreover, comparative analyses with remaining liverwort lineages revealed that the p...

Recently, it has been found in the Far East (Kamchatka and Japan) and Swiss Alps, as well as the Giant Mountains (Sudetes, Czech Republic). The plant was also observed in the Carpathians for the first time. A revision of the herbarium collections of M. emarginata (Ehrh.) Dumort. consisting of 102 specimens from the Polish and Slovak Tatra Mountains revealed the occurrence of M. subemarginata at 24 localities, eight of which were in the Polish Tatras. Most of the localities of this species were concentrated in the High Tatras, and only four sites were discovered in the Western Tatras. Marsupella subemarginata has been briefly characterized morphologically and illustrated. The habitat requirements of the species have been described in detail, and the floristic composition of its phytocoenoses has been shown in a phytosociological table consisting of 10 relevés. Marsupella subemarginata is a valuable additio...
