We found negative impacts of <em>Q. rubra<\/em> and negligible impacts of <em>R. pseudoacacia<\/em> on shrub layer alpha diversity metrics. However, the effect of Q. rubra was similar to native F. sylvatica. P. serotina negatively affected functional diversity, but its effects were lower in rich P. sylvestris forests than in poor <em>P. sylvestris<\/em> forests.<br \/>\n<strong>Conclusion<\/strong> The introduction of alien tree species alters ecosystem services and species diversity of shrub layers. The direction and magnitude of these alterations are alien species-specific and context-dependent. Therefore, their management should account for their impacts.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nFaith\u2019s phylogenetic diversity; Functional richness; Shannon\u2019s diversity; Non-metric multidimensional scaling; Stand-level biomass; Undergrowth<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-021-01033-8'  style='float: right; ' ><\/div>\n<p><strong>Publication<\/strong><br \/>\nDyderski, M.K., Jagodzi\u0144ski, A.M.
