These strategies are usually divided into two categories: direct defence that affects the performance of the herbivores, for example, through the production of adverse chemicals and physical impediments (Schoonhoven et al., <span>2005</span>), and indirect defence, whereby plants promote the top-down control of herbivores by recruitment of natural enemies, for example, via the production of shelters, extrafloral nectar or the release of herbivore-induced plant volatiles (Pearse et al., <span>2020</span>). The evolution of plant traits that enhance the top-down control of herbivory is evident in relationships that involve resource-mediated indirect defence, such as the presence of fruit bodies or shelters to house predators (Kessler & Heil, <span>2011</span>). The evolution of such plant traits often coincides with the specialization of predators such as ants, to use the housing and fruit bodies of the plant while offering strong defensive services that reduce plant fitness loss by herbivory (Heil & McKey, <span>2003</span>). The evolution of information-mediated indirect defence by plant volatiles is strongly debated (Kessler & Heil, <span>2011</span>). The attraction of predators and parasitoids by herbivore-induced plant volatiles is likely ubiquitous in all terrestrial ecosystems (Pearse et al., <span>2020</span>; Turlings & Erb, <span>2018</span>). However, only very few studies have identified a link between volatile emission, the attraction of natural enemies and plant fitness (Hare, <span>2011</span>; Kergunteuil et al., <span>2019</span>; Schuman et al., <span>2012</span>).</p>\u0000<p>One general reason for why information-mediated indirect defence may not be evident is that volatiles are used by many other community members that influence the fitness of individual plants (Poelman, <span>2015</span>; Turlings & Erb, <span>2018</span>). A second reason is that parasitoids, a prevalent group of natural enemies that respond to herbivore-induced plant volatiles to locate their herbivorous hosts (Godfray, <span>1994</span>), do not always mitigate the impact of herbivory on plants (Cuny et al., <span>2021</span>; Cuny & Poelman, <span>2022</span>; Pearse et al., <span>2020</span>; van der Meijden & Klinkhamer, <span>2000</span>). In other words, it is unclear whether indirect defence through the release of plant volatiles evolved to specifically attract parasitoids. There are several reasons for this ongoing debate: (1) Some parasitoid species allow the host to grow until the parasitoid larvae are fully grown (Mackauer & Sequeira, <span>1993</span>) and, thus, feeding damage still occurs following parasitism. Hosts parasitized by some species (mostly gregarious ones) inflict even more damage than unparasitized ones (Ode, <span>2006</span>); (2) even if parasitism red","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"21 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143600017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Do trait–growth relationships vary with plant age in fire-prone heathland shrubs?","authors":"Lily P. Dun, Elizabeth H. Wenk, Daniel S. Falster, Mark Westoby, Ian J. Wright","doi":"10.1111/1365-2745.70023","DOIUrl":"https://doi.org/10.1111/1365-2745.70023","url":null,"abstract":"&lt;h2&gt;1 INTRODUCTION&lt;/h2&gt;\u0000&lt;p&gt;Field-measured plant growth rates vary considerably across species, influencing competitive interactions and shaping vegetation patterns across various ecological scales (Lambers &amp; Poorter, &lt;span&gt;1992&lt;/span&gt;). Understanding the factors driving this variation is essential for predicting community dynamics and ecosystem responses to environmental change. Functional traits have been extensively studied as potential drivers of growth rate variability, with some traits generally showing consistent correlations with growth rates across different studies. For example, in numerous studies, faster growth tends to be correlated with lower wood density (WD) and with higher adult maximum height (Fajardo et al., &lt;span&gt;2024&lt;/span&gt;; Gray et al., &lt;span&gt;2019&lt;/span&gt;; Iida et al., &lt;span&gt;2023&lt;/span&gt;; Iida, Kohyama, et al., &lt;span&gt;2014&lt;/span&gt;; King et al., &lt;span&gt;2006&lt;/span&gt;; Kunstler et al., &lt;span&gt;2016&lt;/span&gt;; Poorter et al., &lt;span&gt;2008&lt;/span&gt;, &lt;span&gt;2018&lt;/span&gt;; Rubio et al., &lt;span&gt;2021&lt;/span&gt;; Rüger et al., &lt;span&gt;2012&lt;/span&gt;; Russo et al., &lt;span&gt;2010&lt;/span&gt;; Wright et al., &lt;span&gt;2010&lt;/span&gt;). By contrast, for leaf mass per area (LMA), a key trait in leaf ‘economics’ (Wright et al., &lt;span&gt;2004&lt;/span&gt;), the corresponding knowledge is variable: in some field studies, LMA is positively associated with growth rate (Bin et al., &lt;span&gt;2024&lt;/span&gt;; Gray et al., &lt;span&gt;2019&lt;/span&gt;), in others, the association is negative (Poorter et al., &lt;span&gt;2018&lt;/span&gt;; Poorter &amp; Bongers, &lt;span&gt;2006&lt;/span&gt;), and commonly no relationship is found (Gibert et al., &lt;span&gt;2016&lt;/span&gt;; Hietz et al., &lt;span&gt;2017&lt;/span&gt;; Prado-Junior et al., &lt;span&gt;2017&lt;/span&gt;; Visser et al., &lt;span&gt;2016&lt;/span&gt;; Wright et al., &lt;span&gt;2019&lt;/span&gt;).&lt;/p&gt;\u0000&lt;p&gt;Increasingly, researchers in this area have explored the possibility that trait-growth relationships vary with plant size or age, or developmental stage (Gibert et al., &lt;span&gt;2016&lt;/span&gt;; Iida et al., &lt;span&gt;2023&lt;/span&gt;; Iida, Kohyama, et al., &lt;span&gt;2014&lt;/span&gt;; Iida, Poorter, et al., &lt;span&gt;2014&lt;/span&gt;; Iida &amp; Swenson, &lt;span&gt;2020&lt;/span&gt;; Medeiros et al., &lt;span&gt;2019&lt;/span&gt;; Prado-Junior et al., &lt;span&gt;2017&lt;/span&gt;; Rüger et al., &lt;span&gt;2012&lt;/span&gt;; Visser et al., &lt;span&gt;2016&lt;/span&gt;; Wright et al., &lt;span&gt;2019&lt;/span&gt;; Yang et al., &lt;span&gt;2018&lt;/span&gt;). Plant size or age may help explain discrepancies among reported relationships, for example, for LMA. Generalising across studies is potentially complicated by differences in how growth rate is expressed, that is, as absolute growth rate or as relative growth rate RGR, which itself is strongly size-dependent (He et al., &lt;span&gt;2022&lt;/span&gt;). Generalisation is also complicated by methodological differences in how size-related effects are quantified, for example, by way of meta-analysis (Gibert et al., &lt;span&gt;2016&lt;/span&gt;), by including size as a covariate in a hierarchical Bayesian framework (Iida, Kohyama, et al., &lt;span&gt;2014&lt;/span&gt;; Iida, Poorter, et al., &lt;span&gt;2014&lt;/span&gt;; Rüger et al., &lt;span&gt;20","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"21 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143600044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
