Variation in water requirements may be another important dimension of niche differentiation, but whether and how variability in water requirements affects the partitioning of other resources is unknown. Here, we investigate how body size, dental morphology, and water requirements interactively affect space use and diet of 15 large-herbivore species in Serengeti National Park. Water requirements predicted space use in relation to permanent water sources, while diet type (percentage grass) was best predicted by dental morphology. Food partitioning was best predicted by a combination of all three traits in both wet and dry seasons. Furthermore, the total explained variation of diet dissimilarity explained almost tripled when these three traits were combined compared to single traits, emphasizing the importance of multiple dimensions of niche differentiation. Our results show that variation in water requirements is strongly associated with spatial and dietary niche differentiation among large herbivores, emphasizing the importance of spatial heterogeneity in surface water and vegetation structure for maintaining the world's last mega-diverse megafaunal assemblages.

There is still no holistic understanding of how the organization of belowground mycorrhizal root structure and fungi in the nutrient acquisition continuum shifts with forest age and soil resources, which restrains our understanding of the functional relations among roots, fungi, and soil. Here, we examined shifts in the absorptive root, mycorrhizal strategies, and soil-associated fungal community compositions after 9 years of nitrogen manipulation (0, 20, and 50 kg N ha<sup>−1</sup> year<sup>−1</sup>) in temperate larch forests across three age cohorts (11, 20, and 45 years). We found that the effect of forest age on root and fungal traits outweighs that of nitrogen treatment. Specifically, with increasing forest tree age, root respiration and specific root length decreased, while protective investments such as tissue density and phenolics increased. Meanwhile, the proportion of ectomycorrhizal fungi of the long-distance exploration type decreased, but those of the short-distance exploration type increased. Together, these patterns suggest a forest age-mediated nutrient acquisition continuum spanning from “explorative roots with long-distance exploration types” to “conservative roots with short-distance exploration types.” We propose that this nutrient acquisition continuum is functionally constrained by the “size vs. rate” trade-off between the root architecture and root segment metabolism, and the “roots vs. mycorrhizal fungi” complementarity between root architecture and mycorrhizal exploration types.

We demonstrate that incorporating these sources of variation significantly improves predictions of ecological dynamics compared to the outcomes of typical models, which hold interaction strengths constant. We compared the performance of models based on different functions of neighbor density and identity in describing population trajectories (i.e., persistence over time) and community dynamics (i.e., temporal stability, synchrony, and degree of oscillation) in simulated two-species communities and a real, diverse annual plant system. In our simulated communities, we observed the highest level of coexistence between species pairs when species interactions varied from competitive to facilitative, depending on neighbor density (i.e., following a sigmoid function). Introducing within-guild facilitation through a nonlinear bounded function allowed populations, both simulated and empirical, to avoid extinction or runaway growth. In fact, nonlinear bounded functions (i.e., exponential and sigmoid functions) accurately predicted population trends over time within the range of abundances observed over the last 10 years. With the sigmoid function, the simulated communities of two species exhibited a higher probability of synchrony and oscillation compared to other functional forms. These simulated communities did not always show temporal stability, even when they were predicted to coexist. Overall, varying species interactions lead to realistic ecological trajectories and community dynamics when bounded by asymptotes based on neighbor density.

We synthesize developments in coexistence theory into a general theoretical framework linking community coexistence to ecosystem function. Our framework, which we term functional coexistence theory, identifies three components determining the total function of a community of coexisting species. The first component directly corresponds to the niche differences that enable pairwise species coexistence and to the complementarity component from the additive partition of biodiversity effects. The second component measures whether higher functioning species also have higher fitness under competition, providing a missing link between the additive partition's selection effect and modern coexistence theory's concept of equalization. The third component is least well studied: reducing functional imbalances between species increases niche difference's positive effect on function. Using a mechanistic model of resource competition, we show that our framework can link the structure and function of multispecies communities and that it can predict changes in coexistence and ecosystem function along gradients of resource availability. In particular, we expect the effect of resource level on biodiversity–function relationships to be limited in magnitude and variable in sign because it should be primarily mediated by fitness. Next, we confirm our theoretical expectations by fitting this model to data from a classic plant competition experiment. Finally, we apply our framework to simulations of multiple ecosystem functions, demonstrating that relationships between niche, fitness, and function also predict a community's multifunctionality, or ability to simultaneously show high levels of multiple functions.

Here, we disentangle two contributions to variation in plant–fungus interactions along geographic and environmental gradients of the Arctic: abiotic impacts on the pool of fungal species present in the soil, and abiotic <i>and</i> biotic impacts on variation in the pool of fungi associated with plant roots. Given the low species richness and harsh conditions in the Arctic, we expected opportunistic associations to emerge, along with strong impacts of the environment on interaction structure. Across multiple spatial scales, we sampled roots of 12 widely distributed plant taxa. To characterize the pool of species available for colonization, we quantified the pool of fungi present in the soil, and to characterize realized interactions, we quantified root-associated fungal communities. Data from DNA metabarcoding of each fungal community were modeled by Hierarchical Modeling of Species Communities (HMSC). To determine whether the realized networks deviated from random expectations, we compared the observed networks to those expected under null models. Overall, we found strong support for opportunistic associations, along with some level of selectivity. Fungal communities within the soil and rhizosphere shared 85% of their fungal genera, but the composition of these communities significantly differed among ecosystem compartments. The two compartments showed similar responses to the environment, with low levels of partner fidelity among both plant and fungal taxa. Plant–fungus networks showed a distinctly nonrandom structure, which was driven by gradients in pH and temperature. Across the Arctic, the structure of fungal communities in the plant rhizosphere is thus mainly driven by abiotic rather than by biotic conditions (i.e., host identity or microbes–microbes associations). Environmental conditions will dictate what interaction partners occur where, but interactions among locally occurring plants and fungi are dominated by opportunistic partner choice.

Predicting plant community-level outcomes based on these greenhouse experimental results implicitly assumes that plant–soil microbe interactions remain constant through time. However, a growing body of research points to a complex temporal trajectory of plant–soil microbe interactions, with microbial effects varying with the conditioning duration, plant development, and time since conditioning.

Yet, the study of community dynamics often relies on values averaged at the species level, ignoring how intraspecific variation can affect those dynamics. We developed a theoretical approach to evaluate the extent to which variation within populations, in terms of interactions, can influence structural stability, a robust measure of species' likelihood of persistence in mutualistic systems. Next, we examine how intraspecific variation in mutualistic interactions affects species' persistence theoretically in a simplified community, which provides a solid foundation for contextualizing empirical results. This theoretical exploration revealed that differences in the benefits received by different individual types by mutualistic partners, as driven by the way interactions are distributed among those types due to individual specialization, strongly influence species persistence. Building on these insights, we move beyond the theoretical framework and work through an empirical case study involving three co-occurring plant species. Drawing from detailed field data on plant–pollinator interactions and plant fitness, we quantify intraspecific variation in the mutualistic benefits received by plants and incorporate this variation into estimations of structural stability. Through explicit consideration of this facet of intraspecific variation, we found that, for all three focal plant species, populations composed of individuals specialized in pollinator use promote the persistence of the plant species they belong to and their associated pollinator community, only in the absence of heterospecific plant competitors. However, more importantly, these positive effects do not hold when plant species compete with a broader, diverse plant community. In this case, two of the focal plant populations are more vulnerable when they comprise more specialized individuals and therefore are less likely to persist. By integrating the proposed theoretical approach with empirical data, this study highlights the importance of individual variation in promoting species persistence in mutualistic systems.
