Increases in the frequency and severity of tundra fires have the potential to catalyse vegetation transitions with far‐reaching local, regional and global consequences. We propose that post‐fire tundra recovery, coupled with climate change, may not necessarily lead to pre‐fire conditions. Our hypothesis, based on surveys and literature, suggests two climate–fire driven trajectories. One trajectory results in increased woody vegetation under low fire frequency; the other results in grass dominance under high frequency. Future research should address uncertainties regarding possible tundra ecosystem shifts linked to fires, using methods that encompass greater temporal and spatial scales than previously addressed. More case studies, especially in underrepresented regions and ecosystem types, are essential to broaden the empirical basis for forecasts and potential fire management strategies. Synthesis. Our review synthesises current knowledge on post‐fire vegetation trajectories in Arctic tundra ecosystems, highlighting potential transitions and alternative ecosystem states and their implications. We discuss challenges in defining and predicting these trajectories as well as future directions.

Such filtering is intense during early life stages, such as that of forest tree seedlings (Green et al., 2014; Grubb, 1977). Light, water and mineral nutrients are important factors limiting the performance of tree seedlings (Coomes & Grubb, 2000). While some stresses are primarily imposed by the physical environment (e.g. low temperatures, drought, low soil fertility; Comita & Engelbrecht, 2014; Lusk et al., 2015; Richardson et al., 2013), others originate from, or are intensified by, understorey or canopy components of the forest that reduce light availability or cause physical damage through litterfall from large tree fern or palm fronds (Beckage & Clark, 2003; Clark & Clark, 1991; Coomes et al., 2005; George & Bazzaz, 1999; Lusk & del Pozo, 2002). Many studies that measure seedling survival with respect to abiotic and biotic filters are conducted at small spatial scales that only partially sample environmental gradients, and it is difficult to ascertain their generality (Estes et al., 2018). However, given accelerating global environmental change, understanding drivers across environmental gradients and scales matching underlying processes is critical to better predict the future of forest communities (McDowell et al., 2020).\u0000Plants trade off growth in optimal conditions against survival and stress tolerance (Kambach et al., 2025; Reich, 2014). Conifers and angiosperms exemplify this trade-off as many conifers have conservative traits that enable persistence in stressed environments while many angiosperms have faster growth rates but suffer shorter longevity (Brodribb et al., 2012; Enright & Ogden, 1996). Conifers have physiological constraints, such as poor water conduction by tracheids and limited total leaf area in seedlings, resulting in slow growth (Augusto et al., 2014). However, conifers often persist on low nutrient sites due to their thrifty use of nutrients achieved through longer-lived leaves. In contrast, the more efficient water transport systems of angiosperms based on xylem vessels are often more susceptible to frost or drought due to embolism (Lusk et al., 2015). Bond (1989) put forward the ‘slow seedling’ hypothesis as an explanation of why conifers are often scarce as seedlings but may dominate canopies, by suggesting that the observed low frequency of conifer seedlings may be traded off with higher survival than angiosperms. The combination of environmental conditions and plant growth strategies can lead to differences in survival because optimal adaptation to all relevant environments at the same time is n","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"87 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143608707","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}

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., 2005), 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., 2020). 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, 2011). 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, 2003). The evolution of information-mediated indirect defence by plant volatiles is strongly debated (Kessler & Heil, 2011). The attraction of predators and parasitoids by herbivore-induced plant volatiles is likely ubiquitous in all terrestrial ecosystems (Pearse et al., 2020; Turlings & Erb, 2018). However, only very few studies have identified a link between volatile emission, the attraction of natural enemies and plant fitness (Hare, 2011; Kergunteuil et al., 2019; Schuman et al., 2012).\u0000One 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, 2015; Turlings & Erb, 2018). 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, 1994), do not always mitigate the impact of herbivory on plants (Cuny et al., 2021; Cuny & Poelman, 2022; Pearse et al., 2020; van der Meijden & Klinkhamer, 2000). 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, 1993) and, thus, feeding damage still occurs following parasitism. Hosts parasitized by some species (mostly gregarious ones) inflict even more damage than unparasitized ones (Ode, 2006); (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}

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., 2024; Gray et al., 2019; Iida et al., 2023; Iida, Kohyama, et al., 2014; King et al., 2006; Kunstler et al., 2016; Poorter et al., 2008, 2018; Rubio et al., 2021; Rüger et al., 2012; Russo et al., 2010; Wright et al., 2010). By contrast, for leaf mass per area (LMA), a key trait in leaf ‘economics’ (Wright et al., 2004), the corresponding knowledge is variable: in some field studies, LMA is positively associated with growth rate (Bin et al., 2024; Gray et al., 2019), in others, the association is negative (Poorter et al., 2018; Poorter & Bongers, 2006), and commonly no relationship is found (Gibert et al., 2016; Hietz et al., 2017; Prado-Junior et al., 2017; Visser et al., 2016; Wright et al., 2019).\u0000Increasingly, researchers in this area have explored the possibility that trait-growth relationships vary with plant size or age, or developmental stage (Gibert et al., 2016; Iida et al., 2023; Iida, Kohyama, et al., 2014; Iida, Poorter, et al., 2014; Iida & Swenson, 2020; Medeiros et al., 2019; Prado-Junior et al., 2017; Rüger et al., 2012; Visser et al., 2016; Wright et al., 2019; Yang et al., 2018). 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., 2022). Generalisation is also complicated by methodological differences in how size-related effects are quantified, for example, by way of meta-analysis (Gibert et al., 2016), by including size as a covariate in a hierarchical Bayesian framework (Iida, Kohyama, et al., 2014; Iida, Poorter, et al., 2014; Rüger et al., 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}

Because seed morphology and germination directly influence seedling exposure to resources and environment, these two stages may be linked through trait synergies and trade‐offs that coordinate functioning through early ontogeny. However, the wide range of traits impacting environmental response at each ontogenetic stage are rarely explored in tandem to understand the potential dimensionality of the functional recruitment niche. We explored covariation among 13 seed and seedling traits linked to stress tolerance, rate of germination or growth, light response, temperature response and other functions for 49 species found in semi‐arid rangelands. Using phylogenetically informed ordination and cluster analysis, we asked how trait covariation across multiple ontogenetic stages and functions shapes the dimensionality of the functional recruitment niche. The first two trait dimensions identified at separate seed and seedling stages aligned, providing some basis for ontogenetic coordination during recruitment. Morphological traits reflecting size‐related stress tolerance (i.e. seed and seedling mass) formed the strongest foundation for coordination across stages, sharing ties with traits reflecting seedling light response (specific leaf area), growth rate (root elongation) and seed temperature response (e.g. germination minimum temperature). We also observed an unexpected trade‐off in how seeds and seedlings may avoid risk (through dormancy) or tolerate risk (through root investment), respectively. In contrast, seed light response, seed germination rate and seedling minimum temperature thresholds were not tightly linked to analogous functions at other stages. Their independence could expand the dimensionality of the recruitment niche depending on the functional significance of these traits in the field. Synthesis. Seed and seedling stages are characterized by multiple, independent dimensions of functioning, but ontogenetic coordination may moderate increasing dimensionality of the functional recruitment niche as a wider breadth of traits are explored together. At the same time, physiological traits linked to environmental response appear less connected to other traits and could complexify spatiotemporal recruitment dynamics. Both the independent and coordinated aspects of functioning observed here deserve exploration across a broader range of species, traits and environments to understand the full dimensionality of the functional recruitment niche.
