Niche Conservatism and the Future Potential Range of Epipactis helleborine (Orchidaceae)

摘要: The aim of the present study was to evaluate current distribution suitable niches for invasive orchid species, Epipactis helleborine, and estimate possibility its further expansion. Moreover, niche modeling tools were used explain rapid expansion in North America test conservatism species. maximum entropy method create models distribution. A database E. helleborine localities prepared based on examination herbarium specimens, information from electronic databases as well data gathered during field works. differences between occupied by native populations evaluated using overlap identity indexes. coverage most habitats species measured three future scenarios time model. Populations occupy American west coast very similar those preferred native, Eurasian populations, while east is related shift. created indicate that does not realize potential range. total surface potentially available will decrease all climate change 2080.
