The impacts of droughts on plant communities and their associated ecosystem functions are well appreciated. For example, droughts can alter community composition (Gao et al., 2022; Hoover et al., 2014; Xu et al., 2021) and drive significant reductions in primary productivity (Gao et al., 2019; Liu et al., 2023; Su et al., 2022), and these impacts often persist post-drought (‘drought legacies’; Müller & Bahn, 2022; Vilonen et al., 2022). The consequences of highly wet periods, by contrast, have thus far received less attention, despite heavy rainfall events increasing over the past century throughout the contiguous United States and in many other regions worldwide (IPCC, 2021; Jay et al., 2018). Further, the impacts of extreme wet and dry events are often evaluated independently (although see Isbell et al., 2015; Sala et al., 2012; Wilcox et al., 2017), despite both types of ‘precipitation events’ (see Box 1) increasing in many regions. Therefore, to persist and maintain critical ecosystem functions plant communities must be resilient to both of these contrasting precipitation events.\u0000<div>\u0000<h3>BOX 1.

However, it is unknown how BN is represented by different plant organs and to what extent environment or evolution affects BN. We measured C, N, P, K, Ca and Mg concentrations in leaves, stems and roots of 1022 individuals of 62 Artemisia species collected across China to quantify BNs of the three organs. The BN of leaves was offset from and smaller in volume than that of stems and roots. BNs of the three organs differed in their sensitivities to environmental gradients, and leaves were less responsive to environmental variation than stems and roots in both BN volumes and positions. Environmental gradients had larger effects on BN positions than on BN volumes of all three organs. The BN volumes and positions of leaves and roots had no phylogenetic signal, while stem BN had a weak signal, that is, repeated species divergences from various Artemisia branches explained most of the BN variation of the three organs. The BN hypothesis cannot be fully tested using the elemental composition of a single organ owing to different physiological mechanisms and diverse responses of BN among organs. At least in Artemisia, leaves are strongly constrained in a limited elemental niche space to support a relatively stable supply of elements for leaf functioning, especially photosynthesis. In contrast, stems and roots develop larger elemental hypervolumes also representing nutrient storage and other functions. The BNs of Artemisia showed different environmental responses between volumes and positions, allowing these species to adjust elemental concentrations while maintaining a stable overall elemental composition under different environmental conditions. Synthesis. In conclusion, BNs of extant Artemisia populations are determined mostly by short‐term phenotypic responses to current environmental conditions and/or genotypic variation, while the recently evolved species diversity results mostly from species‐specific and organ‐specific use of nutrients and little by early divergence in the phylogeny.

Many mesic temperate forests in North America, Europe and Asia have become more even aged, undergone severe fire suppression and experienced increased ungulate browsing (Carpio et al., 2021; Frelich, 2002; Hai et al., 2023; McDowell et al., 2020; Pascual-Rico et al., 2021). These altered conditions create adverse environments for the plant species that coevolved and depend on historic disturbance patterns, such as globally dispersed oak (Quercus) species (Carrero et al., 2020; Tinner et al., 2005). Changes in plant composition with altered disturbance regimes have led managers to restore or manipulate disturbance to support biodiversity and ecosystem function (Long, 2009; Stanturf et al., 2014). However, our understanding of how the reintroduction of multiple historic disturbances influences biodiversity is nascent and represents a key knowledge gap in our long-term management and restoration of temperate forest systems.\u0000Mesic North American forests are expansive ecosystems that have experienced dramatic alterations in their disturbance regimes over the last century (Abrams, 2005; Hanberry & Nowacki, 2016; Vander Yacht et al., 2020; Webster et al., 2018). This scenario is particularly acute in Appalachian hardwood forests, which have lost oak (Quercus spp.) tree regeneration and are transitioning to wetter, maple-dominated (Acer spp.) systems (Nowacki & Abrams, 2008; Pile Knapp et al., 2024). This transition from oak to maple forests was initiated by the forced removal of Indigenous peoples and their use of cultural burning as a management tool (Abrams et al., 2021; Pile Knapp et al., 2024; Poulos, 2015). This was followed by mass deforestation and slash wildfires in the late 19th and early 20th century (Lafon et al., 2017). Negative perceptions of these wildfires led to a century of state-sanctioned fire exclusion and suppression that favoured maple growth and wetter understories (Alexander et al., 2021; Arthur et al., 2021). As a result, Appalachian forests became dominated by even-aged stands with few mid-sized and large (>15-m diameter; >175 m2) canopy gaps and infrequent low-intensity fires (Clebsch & Busing, 1989; Nowacki & Abrams, 2008; Raymond et al., 2009).

During the 19th and 20th centuries, the baseline for the temperate lowlands of Europe was a continuous primeval forest dominated by broadleaved deciduous trees (reviewed by Vera, 2000). This hypothesis was mainly founded on the observation that fields and meadows can spontaneously develop into forests after the abandonment of agriculture and livestock farming. The baseline of the primeval forest was challenged by Frans Vera (2000) in his influential book Grazing Ecology and Forest History where the author presented diverse and compelling evidence supporting an alternative hypothesis: grazing and browsing by extinct megaherbivores should have created and maintained wood pastures, which must have been a widespread landscape type in post-glacial temperate Europe (Vera, 2000). The book contains perspectives from succession ecology, plant regeneration, palynology, paleoecology, history and even linguistics (Vera, 2000). Recently, a large-scale palynological study (Pearce et al., 2023) has provided further support to Vera's hypothesis by estimating that light woodland (shade-intolerant taxa) and open vegetation covered more than half of European landscapes during the Last Interglacial period (129,000–116,000 years ago). In parallel, another study has estimated a loss of ~95% of community-wide biomass of European megafauna (wild terrestrial mammals ≥10 kg) since the Last Interglacial along with the loss of the largest species of megaherbivores, including elephants and rhinos (Davoli et al., 2024). In addition, a further palynological study suggests that the vegetation composition in the Last Interglacial is better explained by the role of megaherbivores than by fire regimes (Pearce et al., 2024).\u0000Hence, current evidence supports that the temperate zone of Europe was not a closed continuous forest, but a more heterogeneous biome with open vegetation (mainly grasslands), light woodlands and forests (Pearce et al., 2023) that held a diverse community of large herbivorous mammals (Davoli et al., 2024; Svenning et al., 2024). This is congruent with the fact that many temperate woody plants are light-demanding species that are often restricted to forest edges because they fail to regenerate in the shaded forest interiors (Vera, 2000). Moreover, many light-demanding plants are thorny (e.g. Berberis vulgaris, Crataegus spp., Prunus spinosa, Rosa spp., Rubus spp. and Ulex europaeus) or have prickly leaves (e.g. Ilex aquifolium and Juniperus spp.). These are defensive traits a","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"28 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142793557","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}
