“…e Ukrainian Carpathian Region (UCR), being part of the Eastern Carpathians and including surrounding foothills and lowlands, is subdivided into 57 geomorphological mesoregions (Novikov, 2021a). In general, in the UCR, there are present 21 unequally distributed Aconitum taxa of the speci c and infraspeci c level, including ten species of the native ora (Noviko et al, 2016;Onyshchenko et al, 2021).…”

Basing on 2054 georeferenced occurrences of ten Aconitum species, the initial map of the species richness per each of 57 operational geographic units (OGU) of the Ukrainian Carpathian Region (UCR) has been developed. Next, to avoid unequal data distribution, we counted absolute species presence per OGU, based on which we calculated ‘rarity-weighted richness’ (RWR) and performed parsimony analysis. As a result, we found that Chornohora and Svydovets made a strongly supported cluster with the highest Aconitum species diversity and demonstrated the highest RWR values, hence being the main hot-spot of the genus distribution in the UCR. This main hot-spot also spreads to adjacent mountain ranges, including Maramures and Gorgany. Probably, a continuous gradient of Aconitum taxonomic richness from southeast toward northwest of the UCR existed before. The gap in Polonyna Borzhava, located between Polonyna Rivna and Polonyna Rivna, can be secondarily resulted by the high level of anthropogenic transformation of this region. Contrary, the high RWR value and distinct clustering of the Polonyna Rivna supported the presence of a local isolated Aconitum hot-spot related to two prominent mountain peaks located here – Runa-Plai Mt. (in Polonyna Rivna) and Pikui Mt. (in adjacen Waterdivided Mountain Range).

Aconitum bucovinense Zapał. is the European species of monkshood, endemic to the Eastern and Southern Carpathians. A protocol has been developed for the in vitro regeneration of adventitious shoots by indirect organogenesis from leaf explants. An initiation of cultures carried out on a medium with picloram and kinetin allowed obtaining a callus. More than a 200% FM increase of the callus and at the same time differentiation of adventitious buds were obtained on IBA and BAP supplemented media. Excised buds were used to establish shoot cultures and multiplied after a transfer to nutrient media with an addition of BAP with IBA, IAA or NAA. Almost 70% of rooted shoots were obtained on a 1.5 mg L − 1 IBA and 1.0 mg L − 1 BAP supplemented medium with simultaneous e cient multiplication. An analysis of peroxidase activity revealed its gradual increase in shoots until the appearance of roots. For the rst time, an e cient way to regenerate, multiply and root A. bucovinense shoots has been developed and can be used for ex situ conservation of this species. Key MassageThe system of plant regeneration of Aconitum bucovinense from callus culture was elaborated. The analysis of the peroxidase level showed that its content increases until the rst roots appear.
