Grazing, the most widespread use of grasslands, influences productivity in response to climatic extremes by shaping community structure. Since grazing could disrupt normal plant growth and reproduction, rest from grazing at various stages of the growing season may have different effects on above‐ and below‐ground community properties. However, how grazing or grazing rest at different stages of growing season affects grassland stability when facing extreme snowfall reduction remains unclear.</jats:list-item> <jats:list-item>We investigated the multidimensional stability (resistance, resilience, recovery and temporal stability) of above‐ground net primary productivity (ANPP) under a time‐dependent strategic‐rest grazing practice (rest in early, peak and late growing stage) experiment, during which a natural extreme snowfall reduction event occurred. We also assessed plant richness, dominance, asynchrony, key functional group stability and below‐ground bud density to explore the mechanisms underlying multidimensional stability.</jats:list-item> <jats:list-item>We found that extreme snowfall reduction significantly decreased grassland ANPP under all grazing practices. However, grazing with short‐term rest during the peak growing stage significantly enhanced ANPP, improved resistance and recovery from extreme snowfall reduction, and consequently greatly improved the temporal stability compared to continuous grazing. In contrast, the grazing rest during the early and late growing stages did not improve temporal stability of ANPP. Meanwhile, resilience was not affected by grazing practices. The benefits of peak rest primarily arise from allowing the formation of sufficient below‐ground buds before and after extreme events. Notably, changes in community properties (such as diversity or asynchrony) resulting from the rest were not correlated with resistance and recovery. Additionally, the increases in grass bud density from the peak rest indirectly contributed to temporal stability by enhancing the stability of perennial rhizome grass and preserving community composition.</jats:list-item> <jats:list-item><jats:italic>Synthesis.</jats:italic> These findings underscore the essential role of plant below‐ground buds in sustaining stable grassland productivity in response to snowfall reduction and also suggest that grassland management strategies should account for the protection of plant asexual reproductive organs, which contributes to grassland sustainability in the face of future climate change.</jats:list-item> </jats:list>","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"68 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143427173","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}

This impact has been notable on European beech (<jats:italic>Fagus sylvatica</jats:italic> L.), particularly at the core of its distribution, causing concern among forest stakeholders and questions about the resilience capacity of beech trees. The objective of this study is to investigate the physiological processes linked to water and carbon constraints involved in the resilience of beech cambial growth to drought.</jats:list-item> <jats:list-item>We selected 56 beech trees distributed in four plots in north‐eastern France with different soil water deficits characterized retrospectively by a water balance model. Functional traits including tree ring width, wood anatomical traits and stable isotopes (e.g. δ<jats:sup>13</jats:sup>C and δ<jats:sup>18</jats:sup>O) were measured to retrospectively assess the effect of recent recurrent drought in 2015, 2018–2020, and 2022.</jats:list-item> <jats:list-item>Decreased tree growth and increased δ<jats:sup>18</jats:sup>O and intrinsic water use efficiency (iWUE) were observed due to soil water shortage, whereas xylem vessel size and theoretical specific xylem hydraulic conductivity (<jats:italic>K</jats:italic><jats:sub>th</jats:sub>) did not show obvious changes. Vessel density was negatively correlated with annual ring width index and was highly sensitive to drought. δ<jats:sup>13</jats:sup>C, δ<jats:sup>18</jats:sup>O and iWUE were not significantly related to tree ring width index. The plot that experienced the most severe drought intensity in 2018–2020 showed a significant decrease in tree growth resistance and resilience compared to its resistance and resilience during the 2015 drought event. Surprisingly, growth resilience was not associated with tree anatomical and isotopic traits.</jats:list-item> <jats:list-item><jats:italic>Synthesis</jats:italic>. Our results demonstrate that beech xylem structure responds to drought by adjusting the radial growth of tree rings with a relatively stable vessel diameter. Our study also highlights the impact of consecutive or recurrent drought in reducing beech tree resistance and resilience, particularly at sites with higher drought intensity. Tree resilience does not seem to involve changes in traits that would promote the hydraulic functioning to better cope with future soil water shortages.</jats:list-item> </jats:list>","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"36 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143435021","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}

Holt","doi":"10.1111/1365-2745.70002","DOIUrl":"https://doi.org/10.1111/1365-2745.70002","url":null,"abstract":"&lt;h2&gt;1 INTRODUCTION&lt;/h2&gt;\u0000&lt;p&gt;Emerging infectious plant diseases threaten natural communities, agricultural crops (Nazarov et al., &lt;span&gt;2020&lt;/span&gt;) and food security (Brooks et al., &lt;span&gt;2021&lt;/span&gt;; Fones et al., &lt;span&gt;2020&lt;/span&gt;; Ristaino et al., &lt;span&gt;2021&lt;/span&gt;; Savary &amp; Willocquet, &lt;span&gt;2020&lt;/span&gt;), and synergize with other global change factors to exacerbate already declining plant communities (Anderson et al., &lt;span&gt;2004&lt;/span&gt;). For example, when plant invaders accumulate pathogens that spill over onto native competitors, emerging infectious disease can magnify negative invader impacts on native flora (Kendig et al., &lt;span&gt;2022&lt;/span&gt;). A major challenge in understanding and controlling emerging disease outbreaks and spillover is predicting which populations are most at risk. Because the potential for outbreaks can be modulated by other community members (Power &amp; Mitchell, &lt;span&gt;2004&lt;/span&gt;), monitoring for disease emergence and spillover requires surveilling not only a population of concern (the focal host), but also the full community within which it is imbedded.&lt;/p&gt;\u0000&lt;p&gt;Disease spillover requires movement of infectious propagules from an individual of one host species (a reservoir host) to an individual of a second species (a focal host). Such a process can take one of two main forms: (i) there is an initial spillover event (i.e. propagule movement between two individuals of different species), with no further transmission needed to sustain disease in the focal host, or (ii) disease following the initial spillover event is augmented by further spillover events (Lloyd-Smith et al., &lt;span&gt;2009&lt;/span&gt;; Power &amp; Mitchell, &lt;span&gt;2004&lt;/span&gt;). In the zoonotic and wildlife disease literature (e.g. see Lloyd-Smith et al., &lt;span&gt;2009&lt;/span&gt;), these two spillover types have qualitatively different implications for disease establishment as understood by &lt;span data-altimg=\"/cms/asset/23ee2621-fddf-4766-9930-f9a5529eae1d/jec70002-math-0001.png\"&gt;&lt;/span&gt;&lt;mjx-container ctxtmenu_counter=\"0\" ctxtmenu_oldtabindex=\"1\" role=\"application\" sre-explorer- style=\"position: relative;\" tabindex=\"0\"&gt;&lt;mjx-lazy aria-hidden=\"true\" data-mjx-lazy=\"0\"&gt;&lt;/mjx-lazy&gt;&lt;mjx-assistive-mml display=\"inline\" unselectable=\"on\"&gt;&lt;math data-semantic-=\"\" data-semantic-role=\"unknown\" data-semantic-speech=\"\" data-semantic-type=\"empty\" xmlns=\"http://www.w3.org/1998/Math/MathML\"&gt;&lt;/math&gt;&lt;/mjx-assistive-mml&gt;&lt;/mjx-container&gt; (the average number of new infections, resulting from an initial infection event).
