We show that habitat-dependent mortality in a pedunculate oak ( <em>Quercus robur<\/em> L.) seedling cohort reshapes the effective fecundity of individual mother trees but has little effect on the cohort\u2019s genetic diversity.<\/p>\n<p><strong>Abstract<\/strong><\/p>\n<p align=\"justify\"><strong>Context<\/strong> Initial tree recruitment plays a key role in forest regeneration, yet little is known on how patterns of recruit mortality feed back on the fecundity of reproducing trees.<br \/>\n<strong>Aims<\/strong> To investigate how among-habitat variation in seedling arrival and survival alters initial patterns of genetic diversity and maternal reproductive success.<br \/>\n<strong>Methods<\/strong> We genotyped a pedunculate oak seedling cohort (n\u2009=\u2009809) and monitored it over 3 years. The mother trees of 81% of the seedlings were identified through parentage analysis. Seedlings were assigned to one of three habitats (broadleaved forest, pine plantation, or open area).<br \/>\n<strong>Results<\/strong> Broadleaved forest received most seedlings (\u2248\u200965%) but their survival was reduced by a third compared with pine plantations or open areas. Thus, mother trees dispersing many descendants to broadleaved forest suffered a disproportionate reduction of their reproductive success. Genetic diversity did not vary among habitats, nor over the monitoring period.<br \/>\n<strong>Conclusion<\/strong> The quality of seed dispersal, in terms of delivery sites, can considerably influence the reproductive success of individual mother trees without affecting the overall genetic diversity of the recruits.<\/p>\n<p><strong>Keywords<\/strong><br \/>\nGenetic diversity; <em>Quercus robur<\/em> L.; Reproductive success; Seed dispersal; Seedling; Recruitment<\/p>\n<div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-020-00979-5'  style='float: right; ' ><\/div>\n<p><strong>Publication<\/strong><br \/>\nGerzabek, G., Oddou-Muratorio, S. &amp; Hampe, A.
