This competition may differentially affect non-impacted trees, depending on crown class, disturbance severity, and species-specific responses. The purpose of this study is to elucidate the primary drivers of silver and red maple (<em class=\"EmphasisTypeItalic \">Acer saccharinum<\/em> and <em class=\"EmphasisTypeItalic \">A. rubrum<\/em>) growth following emerald ash borer (EAB, <em class=\"EmphasisTypeItalic \">Agrilus planipennis<\/em>)-induced ash tree (<em class=\"EmphasisTypeItalic \">Fraxinus<\/em> spp.) mortality in riparian forests of northwest Ohio.Using dendroecological approaches, we analyzed the pattern of radial growth in red and silver maples in conjunction with the EAB outbreak. This study revealed growth rates of maples increased 72% following EAB arrival and trees advancing in crown class grew 41% faster than those not advancing. The growth response varied by initial crown class, with trees in the intermediate class responding most dramatically. Furthermore, the positive correlation between relative basal area of ash and the radial growth response of maples indicates the important role of disturbance severity in post-disturbance dynamics. These findings suggest that, although advancement in crown class may allow predictions of \u201cwinners\u201d in forest succession post-disturbance, even trees not changing crown class benefit from decreased competition. Results from this study provide a detailed account of radial growth responses in maples following EAB-induced ash mortality and lend insight into the future canopy composition of ash-dominated riparian forests.<\/p>\n<\/div>\n<div id=\"ASec2\" class=\"AbstractSection\">\n<p class=\"Para\" style=\"text-align: justify\"><div class='altmetric-embed' data-badge-type='donut' data-doi='10.1007\/s13595-016-0602-1'  style='float: right; ' ><\/div><\/p>\n<\/div>\n<p style=\"text-align: justify\"><span style=\"color: #ff6600\"><a style=\"color: #ff6600\" href=\"http:\/\/link.springer.com\/article\/10.1007\/s13595-016-0602-1\"><strong>Read the full paper <\/strong><\/a><\/span><\/p>\n<hr \/>\n<p style=\"text-align: justify\"><span style=\"color: #808000\"><strong>Publication<\/strong><\/span><\/p>\n<p style=\"text-align: justify\">Costilow KC, Knight KS, Flower CE 2017.
