We collated the most geographically and taxonomically broad database of seed dispersal distance. With this collation, we showed a latitudinal gradient in seed dispersal distance, with seeds dispersed on average more than an order of magnitude further at the equator than towards the poles. This pattern is partially explained by plant life-history traits that simultaneously associate with seed dispersal distance and latitude, including dispersal mode and plant height. Species that dispersed far are more likely to be those long-lived species with large, non-dormant seeds. This indicates that spatial dispersal and temporal dispersal are bet-hedging strategies. Since seed dispersal is a complex process, we also evaluate the relative importance of each phase in species having more than one dispersal phase. Dispersal distances of the two diplochorous phases were independent and comparable to that of single-phase dispersal. Therefore, the two phases of diplochory form a coordinated dispersal strategy. These findings allow a better understanding of plant reproductive strategies and a potential avenue to predict the restoration potential, community assembly and species persistence under global changes.<\/p>\n\n\n\n<hr class=\"wp-block-separator is-style-wide\"\/>\n\n\n<p><strong>Speaker:<\/strong> Prof. Sichong Chen<\/p>\n<p><strong>Affiliation: <\/strong>Wuhan Botanical Garden, Chinese Academy of Sciences<\/p>\n<p><strong>Time:<\/strong> 4:30 PM, Tuesday, Aug. 22, 2023<\/p>\n<p><strong>Venue: <\/strong>ZOOM \u4f1a\u8bae\u5e73\u53f0 \u4f1a\u8bae ID\uff1a312 430 8960 \u4f1a\u8bae\u5bc6\u7801 PWD\uff1a666666\u00a0<\/p>\n<p>ZOOM<br \/>\u4f1a\u8bae ID\uff1a312 430 8960<br \/>\u4f1a\u8bae\u5bc6\u7801 PWD\uff1a666666<\/p>\n\n\n<hr class=\"wp-block-separator is-style-wide\"\/>\n\n\n\n<div class=\"wp-container-1 wp-block-group\"><div class=\"wp-block-group__inner-container\">\n<div style=\"height:100px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<\/div><\/div>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Speaker: Prof. Sichong Chen<br \/>\nAffiliation: Wuhan Botanical Garden, Chinese Academy of Sciences<br \/>\nTime: 4:30 PM, Tuesday, Aug. 22, 2023<\/p>\n","protected":false},"author":2,"featured_media":3337,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":[],"categories":[3],"tags":[],"_links":{"self":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/3336"}],"collection":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=3336"}],"version-history":[{"count":1,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/3336\/revisions"}],"predecessor-version":[{"id":3338,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/posts\/3336\/revisions\/3338"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=\/wp\/v2\/media\/3337"}],"wp:attachment":[{"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=3336"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=3336"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/seminar.xtbg.ac.cn\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=3336"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
