Abstract It is increasingly recognized that resource competition and plant–soil feedback (PSF) effects can jointly determine outcomes of plant interactions. However, it less clear whether PSF modulates intraspecific or interspecific intrinsic growth rate. Thus, remains to be answered alters coexistence predictions by changing the competitive ability interacting species (fitness differences) rather altering self‐limitation (niche differences). Here, I examined host‐specific soil inoculum, including target competitor non‐specific inoculum on pairwise interactions four pairs grassland perennials. To explore were persistent dependent availability, studied over a two‐year period under control fertilized conditions. These data then used estimate fitness differences niche differences, predict coexistence. found promote competing plants in two ways. First, increased due intense competitor. Second, competitively inferior was more likely conspecific its negative effect persisted throughout experimental but absent after nutrient addition. In conclusion, increasing reversing dominance. Although have long‐term interactions, they depend abiotic (nutrient) contexts. Therefore, are mitigate inequality prevent exclusion anthropogenic fertilisation.

Feedback between plants and soil microbial communities can be a powerful driver of vegetation dynamics. Plants elicit changes in the microbiome that either promote or suppress conspecifics at same location, thereby regulating population density-dependence species co-existence. Such effects are often attributed to accumulation host-specific antagonistic beneficial microbiota rhizosphere. However, identity host-specificity taxa involved rarely empirically assessed. Here we review evidence for plant-associated microbes propose specific plant-soil feedbacks also driven by generalists. We outline potential mechanisms which generalist pathogens, mutualists decomposers generate differential on plant hosts synthesize existing predict these as function investments into defence, dispersal. Importantly, capacity drive depends not only traits individual but phylogenetic functional diversity communities. Identifying factors specialization generalism plant-microbial interactions modulate impact performance will advance our understanding underlying feedback ways it contributes

Significance Understanding the processes that maintain plant diversity is a key goal in ecology. Many previous studies have shown soil microbes can generate stabilizing or destabilizing feedback loops drive either species coexistence monodominance. However, theory shows microbial controls over also arise through microbially mediated competitive imbalances, which been largely neglected. Using data from 50 studies, we found affect dynamics primarily by generating fitness differences rather than feedbacks. Consequently, absence of other asymmetries among plants, are predicted to exclusion more coexistence. These results underscore need for measuring when evaluating

Species interactions are key drivers of biodiversity and ecosystem stability. Current theoretical frameworks for understanding the role make many assumptions which unfortunately, do not always hold in natural, diverse communities. This mismatch extends to annual plants, a common model system studying coexistence, where typically averaged across environmental conditions transitive competitive hierarchies assumed dominate. We quantify interaction networks community wildflowers Western Australia natural shade gradient at local scales. Whilst competition dominated, intraspecific interspecific facilitation were widespread all categories. Interaction strengths directions varied substantially despite close spatial proximity similar levels species richness, with most interacting different ways under conditions. Contrary expectations, predominantly intransitive. These findings encourage us rethink how we conceive categorize mechanisms driving plant systems.

Abstract Plant–soil feedbacks (PSF) and functional traits are two active but not well theoretically integrated areas of research. However, PSF both affected by life‐history evolution, so the should be related. We provide a conceptual framework to link plant types metrics, hypothesize that individual (plant performance in conspecific vs. heterospecific soil) related fast–slow trait spectrum, whereas pairwise (the sum for species growing each other's soils) dissimilarity. performed meta‐analyses test these hypotheses compiling datasets, one dataset consisting values (specific leaf area, SLA; N concentration, LNC; specific root length, SRL; fine diameter, FRD; height; seed mass), second Our showed were more negative faster‐growing with greater SLA, LNC SRL, supporting growth–defence trade‐off hypothesis. Plant height was positively correlated PSF, perhaps because large, long‐lived plants defend against pathogens better than smaller, shorter‐lived plants. also found larger‐seeded had positive or less likely reflecting tolerance soil pathogens.

AbstractA scientific understanding of the biological world arises when ideas about how nature works are formalized, tested, refined, and then tested again. Although benefits feedback between theoretical empirical research widely acknowledged by ecologists, this link is still not as strong it could be in ecological research. This part because theory, particularly expressed mathematically, can feel inaccessible to empiricists who may have little formal training advanced math. To address persistent barrier, we provide a general accessible guide that covers basic, step-by-step process approach, understand, use theory work. We first give an overview why mathematical created, outline four specific ways both verbal motivate work, finally present practical tool kit for reading aspects theory. hope empowering embrace their work will help move field closer full integration

Abstract Competition plays an important role in shaping species’ spatial distributions. However, it remains unclear where and how competition regulates range limits. In a field experiment with plants originating from low high elevations conducted across elevation gradient the Swiss Alps, we find that both lowland highland species can better persist presence of within, rather than beyond, their ranges. These findings suggest helps set lower upper limits these species. Furthermore, reduced ability pairs or to coexist beyond edges is mainly driven by diminishing niche differences; changes differences relative fitness drive weakening competitive dominance over increasing elevation. results highlight need account for interactions investigate underlying coexistence mechanisms understand current future
