Other claims from this paper (10)
- Observation Nine additional new occurrences of Arnellia fennica were found in the Tatra Mountains, bringing the total to 13.
- Observation Production of gemmae was observed and documented for the first time in the Tatra population of Arnellia fennica.
- Observation Male specimens of the dioecious Arnellia fennica were present in the Tatra population.
- Observation Individuals from all three groups of sites are genetically homogeneous.
- Observation The genetic homogeneity of Arnellia fennica indicates a lack of sexual reproduction.
- Observation The only way of dispersal of Arnellia fennica in the Tatras is through propagule production.
- Mechanism The rarity of Arnellia fennica in the Tatra massif is attributed to an inefficient vegetative reproduction mode and the absence of sexual reproduction.
- Observation Half of the montane sites of Arnellia fennica were located in areas covered by glaciers, per paleoglaciological analysis.
- Observation Some sites of Arnellia fennica were found in the high mountain area.
- Observation Montane localities of Arnellia fennica should be considered secondary, arising after glacier retreat from high-mountain propagule-producing populations.
