Abstract Beta diversity—the variation among community compositions in a region—is fundamental measure of biodiversity. Despite diverse set measures to quantify beta diversity, most have posited that diversity is maximized when each has single distinct species. However, this assumption overlooks the ecological significance species interactions and non-additivity systems, where function behaviour depend on other community. Here, we introduce geometric approach as hypervolume embedding metacommunity. This explicitly accounts for captures idea introducing unique, species-rich composition metacommunity increases diversity. We show our closely linked naturally extends previous information- variation-based while providing unifying framework widely adopted extensions Applying empirical data, address two long-standing questions research—the latitudinal pattern effect sampling effort—and present novel insights were previously obscured by limitations traditional approaches. In sum, reconceptualizes offering an alternative complementary perspective measures, with immediate applicability existing data.

Abstract Species interact in different ways, including competition, facilitation and predation. These interactions can be non‐linear or higher order may depend on time species densities. Although these higher‐order are virtually ubiquitous, they remain poorly understood, as challenging both theoretically empirically. We propose to adapt niche fitness differences from modern coexistence theory apply them over time. As such, not merely inform about coexistence, but provide a deeper understanding of how change. Here, we investigated the exploitation biotic resource (plant) by phytophagous arthropods affects their interactions. performed monoculture competition experiments fit generalized additive mixed model empirical data, which allowed us calculate differences. found that switch between types time, intra‐ interspecific facilitation, strong weak competition.

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.

Ecological assembly-the process of ecological community formation through species introductions-has recently seen exciting theoretical advancements across dynamical, informational, and probabilistic approaches. However, these theories often remain inaccessible to non-theoreticians, they lack a unifying lens. Here, I introduce the assembly graph as an integrative tool connect emerging theories. The visually represents dynamics, where nodes symbolise combinations edges represent transitions driven by introductions. Through lens graphs, review how processes reduce uncertainty in random arrivals (informational approach), identify graphical properties that guarantee coexistence examine class dynamical models constrain topology graphs (dynamical quantify transition probabilities with incomplete information (probabilistic approach). To facilitate empirical testing, also methods decompose complex into smaller, measurable components, well computational tools for deriving graphs. In sum, this math-light progress aims catalyse research towards predictive understanding assembly.

ABSTRACT The mechanism of community stability is a hot topic in the field ecology. Research on grassland has gradually increased, and reseeding native species one main measures to restore degraded desert steppe northwest China. However, little known about changes plant after species. This study established long‐term observation site for steppe. We grazing exclusion plots May 2017 conducted surveys grasslands (0YEX(RS)) before setting up treatment experimental plots. After 3 6 years test, vegetation restoration status plot was investigated, respectively. results showed that increased Shannon‐Wiener index Margalef community. At same time, importance value breadth niche gramineous plants improved, while proportion pairs high overlaps logarithm significant association decreased. general positively correlated, increased. partial least squares path modelling show highly positive effect stability. Both EX (grazing grassland) RS (reseeded models indicate diversity indices influence varying degrees, interspecific linkage coefficients affect mainly overlap. Our research shown can improve intensity competition between resources, leading more stable ultimately increasing These findings provide valuable theoretical support sustainable management

Besides considering compositional distinctiveness metrics, explicitly incorporates associations captures idea adding unique, species‐rich metacommunity increases diversity.
