Paulownia fortunei plantation in temperate broadleaves forest, does it act as an invader?
Non-native plant species have been introduced to provide various goods and services with a wide range of negative and positive effects on the ecosystem. Recently, Paulownia fortunei was introduced to the Hyrcanian forests of Iran, sparking debate over its impact. This study used pair correlation statistics and mark correlation functions to examine interactions between Paulownia fortunei and native trees in a same-aged mixed plantation. The pair correlation statistics graphs generally indicated the attraction or independent relationship between Paulownia and native trees, likely due to the low density of Paulownia in the stand. In contrast, mark correlation function graphs generally indicate the negative or independent type of relationship. To investigate soil properties, tree natural regeneration, and vegetation composition, we compared the two same-aged stands of a Paulownia mixed plantation with native trees (Case) and native trees (Control). After twenty years, soil nitrogen and carbon levels increased in the Case compared to the Control. The natural regeneration showed differences. At the small sapling (under 130 cm), the Control has a higher abundance of Acer velutinum Boiss and Quercus castaneifolia, while Crataegus elbursensis is more abundant in the Case. At the large sapling (above 130 cm), Prunus cerasifera was more in the Case. Indices of diversity, species richness, and evenness showed no significant differences. The absence of major antagonistic effects is likely due to the low density of Paulownia and the plantation's relatively short duration (after 20 years).
期刊介绍:
Acta Oecologica is venue for the publication of original research articles in ecology. We encourage studies in all areas of ecology, including ecosystem ecology, community ecology, population ecology, conservation ecology and evolutionary ecology. There is no bias with respect to taxon, biome or geographic area. Both theoretical and empirical papers are welcome, but combinations are particularly sought. Priority is given to papers based on explicitly stated hypotheses. Acta Oecologica also accepts review papers.
