Other claims from this paper (8)
- Observation R. megapolitanum was detected in 28 of the surveyed dry grasslands.
- Observation Almost 50% of R. megapolitanum populations produced sporophytes.
- Association Sites with and without R. megapolitanum differ significantly in grassland size.
- Association Sites with and without R. megapolitanum differ significantly in soil silt and sand percentages.
- Observation R. megapolitanum has fewer historic herbarium vouchers than occurrences found in the current field survey.
- Observation Sites with and without R. megapolitanum cluster spatially at the landscape scale.
- Method / resource A spatially realistic expansion model showed high similarity between simulated and actual distribution of R. megapolitanum.
- Observation The authors interpret the analyses as showing that R. megapolitanum has been expanding in the investigated area.
