The influence of habitat conditions on abundance and selected individual traits of Arum alpinum in the communities Populetum albae and Tilio cordatae-Carpinetum betuli(Western Carpathians)
Studies of selected habitat conditions,as well as spatiotemporal variability of the number and selected traits of individuals of the species Arum alpinum were carried out in 2020-2021 in the foothills of the Western Carpathians.The investigations were conducted in permanent patches located in the Golesz nature reserve(Patch Ⅰ),near the village of Markowce(Patch Ⅱ),in the Kozigarb nature reserve(Patch Ⅲ),and near the village of Żółków(Patch Ⅳ).Patches Ⅰ and Ⅲ were established in a Tilio cordatae-Carpinetum betuli oak-hornbeam forest with undergrowth dominated by low-growth vegetation with narrow leaves,whereas Patches Ⅱ and Ⅳ were established in a Populetum albae riparian forest with undergrowth dominated by broad-leaved species.The most abundant population of A.alpinum was noted in Patch Ⅰ,but substantial numbers of both vegetative and reproductive individuals were also present in Patches Ⅱ and Ⅳ.The occurrence of temporal variability of individual traits increased from its lowest level in Patch Ⅳ,through Patches Ⅰ and Ⅱ,to its highest level in Patch Ⅲ.The significant positive correlation in all populations between length of petioles and blade dimensions,as well as between length of generative stems and infructescence traits confirmed previous findings.Moreover,we showed that A.alpinum was not closely affiliated with a specific forest community.Significant shading and moist nutrient-rich soils are suitable for this species,while dry soils and excessive insolation may limit the flowering and fruiting of individuals.
