Although many studies have investigated this topic over the past decades, much of the research has been focused on the effect of biodiversity on community stability (Hector et al., 2010; Tilman, 1996; Walter et al., 2021), with little attention paid to the mechanisms of how individual-level differences affect population-level stability (Waddle et al., 2019). Filling this gap is important because it is the variation at the individual level that defines the variation at the population level, and subsequently, the higher ecological levels.\u0000The stability of ecological communities is considered primarily determined by two major mechanisms: the portfolio effect (i.e. statistical averaging) (Doak et al., 1998; Tilman, 1996), where stability increases with the number of species; and the insurance effect, where stability increases with the temporal asynchrony among species (species asynchrony) (Blüthgen et al., 2016; Yachi & Loreau, 1999). One may draw a parallel between community stability and population stability, by which population size is analogous to species richness, and within-population asynchrony among individuals is analogous to species asynchrony. Take tree growth for example, as widely understood, it is strongly regulated by climatic conditions, especially the water–energy balance (Peltier & Ogle, 2020). The fluctuation in climate would thus inevitably cause variation in growth rate. In addition to climate, many other factors such as tree age, genetic and trait variations, and microhabitat conditions could all cause differences in growth rate within a population, thus leading to growth asynchrony of conspecifics (Cater & Chapin III, 2000; Peltier & Ogle, 2020; Takenaka, 2000; Tejedor et al., 2020). Such individual differences allow the growth rates of the faster-growing individuals to compensate those of the slower-growing individuals when averaged across the population, thereby promoting the stability in the population-level mean tree growth rate. This stabilization process has potential ecological significance in mitigating the negative impacts of global change on forest ecosystem. However, little is understood about the extent to which population size and within-population asynchrony can regulate the stability of population-level tree growth rate.\u0000A subtle but important distinction between stabilizing processes at population and community levels lies in the different magnitudes of population size and species richn","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"129 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143393361","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}

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., 2022). 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 & Mitchell, 2004), 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.\u0000Disease 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., 2009; Power & Mitchell, 2004). In the zoonotic and wildlife disease literature (e.g. see Lloyd-Smith et al., 2009), these two spillover types have qualitatively different implications for disease establishment as understood by <mjx-container ctxtmenu_counter=\"0\" ctxtmenu_oldtabindex=\"1\" role=\"application\" sre-explorer- style=\"position: relative;\" tabindex=\"0\"><mjx-lazy aria-hidden=\"true\" data-mjx-lazy=\"0\"></mjx-lazy><mjx-assistive-mml display=\"inline\" unselectable=\"on\"><math data-semantic-=\"\" data-semantic-role=\"unknown\" data-semantic-speech=\"\" data-semantic-type=\"empty\" xmlns=\"http://www.w3.org/1998/Math/MathML\"></math></mjx-assistive-mml></mjx-container> (the average number of new infections, resulting from an initial infection event).

This remarkable diversity has long been thought to be at least partly driven by the association between flowering plants and their pollinators (Darwin, 1862; Harder & Johnson, 2009). At a microevolutionary scale, a wealth of studies have investigated the role of pollinator-mediated selection in the evolution of visual floral traits (Caruso et al., 2019; Harder & Johnson, 2009). Despite their well-established role in attracting pollinating insects, olfactory signals remain less well-studied than visual signals (Raguso, 2008), presumably owing to their typically more complex nature. However, recent literature presents a growing number of studies that documented patterns of within and between population variation in floral scents (e.g. de Manincor et al., 2022; Eisen, Geber, et al., 2022; Friberg et al., 2019; Gfrerer et al., 2021, also reviewed in Delle-Vedove et al., 2017), as well as some studies that investigated phenotypic selection on olfactory signals (e.g. Chapurlat et al., 2019; Gfrerer et al., 2021; Gross et al., 2016; Majetic et al., 2009a; Parachnowitsch et al., 2012) and experimental evolution studies exploring the adaptative dynamics of these particular traits (Gervasi & Schiestl, 2017; Ramos & Schiestl, 2020). Floral scents are usually characterized using two main descriptors: the intensity of scent emission and scent composition. The first descriptor, the scent emission rate, is often thought to increase the distance at which the signal can be perceived by insects, and is therefore predicted to be under directional pollinator-mediated selection. This hypothesis is indirectly supported by studies documenting higher scent emission rates in self-incompatible populations compared to self-compatible ones, where selection on traits responsible for pollinator attraction is expected to be relaxed (Petrén et al., 2021; Zeng et al., 2022). A second line of indirect evidence comes from species with separate sexes (dioecious plants), where male plants commonly emit more scent than females (reviewed in Ashman, 2009, Delle-Vedove et al., 2017). Indeed, (i) sexual selection is expected to be stronger in males compared to females (Arnold, 1994; Bateman, 1948; Delph & Ashman, 2006; Moore & Pannell, 2011), at least in situations where female reproductive success is not pollen limited, and (ii) sexual selection should overlap with pollinator-medi","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"15 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143375371","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}

In forests, individual trees are directly affected by the local climate, which depends on weather conditions, but they are also indirectly affected through competition from neighbouring trees (Jump et al., 2017; Ruiz-Benito et al., 2013). Climate is likely to influence species competitiveness as well as the individual tree's response to competition, leading to changes in tree dynamics (Clark et al., 2011, 2014). Therefore, studying the effect of competition along climatic gradients is key to understanding how individual trees respond to climate and hence, to better grasp how forest species assemblages and structures will vary with climate change (Magalhães et al., 2021).\u0000Several authors have suggested that the effect of competition varies along abiotic stress gradients and is weaker in stressful environments (Bertness & Callaway, 1994; Craine, 2005; Grime, 1979; Maestre et al., 2009; Tilman, 1980). Grime (1979) argued for a weaker competitive effect in less productive and more stressful environments since, for the tree, conserving energy may be a better strategy than competing for the limited resources available when stress is high. However, soon thereafter, Tilman (1980) emphasised the need to clarify which resources are involved. This is especially important in productive environments, where the abundance of below-ground resources leads to intense asymmetric competition for access to light; on the contrary, in stressful environments, the limited availability of water or nutrients in the soil leads to intense competition for access to the below-ground resources. Later on, the stress gradient hypothesis considered not only competition but also facilitation processes (Bertness & Callaway, 1994; Maestre et al., 2009). These authors put forward the idea that the net competition effect should decrease with increasing abiotic stress due to an increase in the frequency of facilitative interactions. One example of direct facilitation is canopy photoprotection in arid areas: direct exposure to strong sunlight could lead to greater heat and desiccation, and excessive irradiance or UV radiation stress (Demmig-Adams & Adams III, 2006; Valladares & Niinemets, 2008). Another example is the beneficial effect of a dense canopy in cold areas, where the canopy layer protects tree organs from fatally low temperatures by limiting the upward dissipation of heat and by reducing the cooling effect of the wind (Charrier et al., 2015).\u0000So far, studies that have attempted to assess how the effect of competition on ","PeriodicalId":191,"journal":{"name":"Journal of Ecology","volume":"62 1","pages":""},"PeriodicalIF":5.5,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143258315","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}
