{"title":"Chinese Seed Trait Database: a curated resource for diaspore traits in the Chinese flora","authors":"Hao-Yu Wang, Xue-Lin Chen, Si-Chong Chen","doi":"10.1111/nph.70296","DOIUrl":"https://doi.org/10.1111/nph.70296","url":null,"abstract":"&lt;h2&gt; Introduction&lt;/h2&gt;\u0000&lt;p&gt;Regeneration marks the beginning of a plant's life cycle, with profound effects on population recruitment, species adaptation, and community resilience to environmental changes (Grubb, &lt;span&gt;1977&lt;/span&gt;). Diaspores, including seeds, fruits, and their appendages (hereafter ‘seeds’), are crucial agents of plant regeneration, possessing a wide range of functional traits related to dispersal and colonisation (Saatkamp &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2019&lt;/span&gt;). Trait-based approaches have been widely used to investigate responses of plants to both biotic and abiotic conditions from individual to ecosystem scales (Díaz &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2016&lt;/span&gt;; He &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2019&lt;/span&gt;). To date, traits of vegetative organs are overrepresented in existing global and regional databases, largely due to the essential roles of leaves in ecological functions and ecosystem services as well as the relative ease of accessing and measuring these traits (Supporting Information Table S1). However, our understanding of plant traits remains incomplete, particularly for those traits that are difficult to measure, such as regenerative traits (known as the ‘Raunkiæran shortfall’; Hortal &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2015&lt;/span&gt;). Several databases have made efforts to address this gap (Table S1). For instance, the TRY database has compiled over 50 distinct seed traits with decent species representation (Kattge &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;), and the GIFT database has also aggregated substantial seed trait data (Weigelt &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;). Some regional databases, such as Rasgos-CL (Alfaro &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;) and LEDA (Kleyer &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2008&lt;/span&gt;), with over 20% seed trait records, have contributed to this field. Nevertheless, seed trait data remain relatively sparse both in terms of trait diversity and record coverage (Table S1). Advancing key research questions in plant science necessitates comprehensive seed trait data, along with associated geographic information (Saatkamp &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2019&lt;/span&gt;). These demands have prompted the recent initiation of several databases focusing on seed germination (Fernández-Pascual &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;), seed dormancy (Rosbakh &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;), and Brazilian rock vegetation seed traits (Ordóñez-Parra &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;). Despite these advances, seed-related data lag far behind those centred on vegetative traits in existing databases (Larson &amp; Funk, &lt;span&gt;2016&lt;/span&gt;; Kattge &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2020&lt;/span&gt;).&lt;/p&gt;\u0000&lt;p&gt;Current research efforts remain disproportionately focused on specific plant communities or habitats within certain regions, leading to heavily regional biases in the current global coverage of seed traits (Silveira &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;). China, which has a wide range of biomes, is renowned for its remarkable floral diversity of over 35 000 vascular plant taxa (Lu &amp; He, &lt;span&gt;2017&lt;/span&gt;).

Symbiotic N fixation (SNF) can play a key role in forest succession (Chapin &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;1994&lt;/span&gt;; Batterman &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2013a&lt;/span&gt;; Sullivan &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2014&lt;/span&gt;; Levy-Varon &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2019&lt;/span&gt;), in the ability of forests to sequester carbon as atmospheric CO&lt;sub&gt;2&lt;/sub&gt; levels rise (Hungate &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2003&lt;/span&gt;; Goll &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2012&lt;/span&gt;; Wieder &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2015&lt;/span&gt;; Sulman &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2019&lt;/span&gt;), and in losses of reactive N via gaseous emissions (Erickson &amp; Perakis, &lt;span&gt;2014&lt;/span&gt;; Kou-Giesbrecht &amp; Menge, &lt;span&gt;2021&lt;/span&gt;) and leaching (Binkley &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;1992&lt;/span&gt;; Compton &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2003&lt;/span&gt;).&lt;/p&gt;\u0000&lt;p&gt;There is evidence that many N-fixing trees are capable of regulating SNF via a facultative SNF strategy (Barron &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2011&lt;/span&gt;; Batterman &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2013b&lt;/span&gt;; Bauters &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2016&lt;/span&gt;; Dovrat &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2018&lt;/span&gt;, &lt;span&gt;2020&lt;/span&gt;; Taylor &amp; Menge, &lt;span&gt;2018&lt;/span&gt;; McCulloch &amp; Porder, &lt;span&gt;2021&lt;/span&gt;): increasing or decreasing SNF in response to changes in N supply relative to N demand (n.b. Menge &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2023&lt;/span&gt;). According to theory, one of the pivotal aspects of facultative SNF is the speed at which N fixers adjust SNF (Menge &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2009&lt;/span&gt;). Adjustments that are slow relative to changes in N supply or N demand create periods of under-fixation (less SNF than is necessary to alleviate N limitation to plant growth) and over-fixation (vice versa). Both under-fixation and over-fixation may reduce the growth rate and competitive ability of a facultative N fixer relative to its neighbors, independent of a cost of being facultative (Menge &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2009&lt;/span&gt;). This reduction in growth and competitive ability results from N limitation when plants are under-fixing and the carbon cost of SNF (Tjepkema &amp; Winship, &lt;span&gt;1980&lt;/span&gt;; Gutschick, &lt;span&gt;1981&lt;/span&gt;) when plants are over-fixing.&lt;/p&gt;\u0000&lt;p&gt;The insight that time lags limit the success of phenotypic plasticity (facultative SNF is an example of phenotypic plasticity) is well known in evolutionary ecology (Padilla &amp; Adolph, &lt;span&gt;1996&lt;/span&gt;; DeWitt &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;1998&lt;/span&gt;; Auld &lt;i&gt;et al&lt;/i&gt;., &lt;span&gt;2010&lt;/span&gt;), which might have consequences for other aspects of SNF strategies.
