Predicting how species diversity changes along environmental gradients is an enduring problem in ecology. In microbes, current theories tend to invoke energy availability and enzyme kinetics as the main drivers of temperature-richness relationships. Here, we derive a general empirically-grounded theory that can explain this phenomenon by linking microbial richness competitive communities variation temperature-dependence their interaction growth rates. Specifically, shape community relationship depends on rapidly strength effective competition between pairs with temperature relative variance Furthermore, it predicts thermal specialist-generalist tradeoff rates alters coexistence shifting balance, causing peak at relatively higher temperatures. Finally, show observed patterns performance curves metabolic traits across extant bacterial taxa indeed sufficient generate variety community-level responses real world. Our results provide new mechanism help temperature-diversity communities, quantitative framework for interlinking physiology diversity.

Temperature regulates the physiology and behaviour of organisms. Thus, changing temperatures impact dynamics species interactions. Considering that consumer–resource interactions underpin ecological communities, impacts warming on stability have been extensively studied. However, a consensus among empirically determined warming–stability relationships clear understanding thereof are lacking. We investigate these systematically by developing simplified theoretical framework incorporates empirical data in three steps. define terms intrinsic oscillations to avoid comparing disparate notions, use one‐dimensional metric convert all empirically‐determined thermal dependence parametersiations into single function, directly compare data. The utilises Rosenzweig–MacArthur model with saturating consumer functional response, which has employed study warming‐stability is applied ectotherm pairs. find support for four different relationships: increases, decreases, hump‐shaped or U‐shaped increasing temperature. diversity relationships, though partly attributable context‐dependence, fundamentally caused two factors. First, relative sensitivities attack rate handling time and, second, scarcity evidence carrying capacity. former depends how processes measured, may not be consistent across studies. latter necessitates application assumptions, difficult verify, yet significant relationships. demonstrate aspects data, such as aforementioned factors range studied temperatures, can alter predicted stability. we illustrate our facilitates interactions, from producing concise overview predictions analysing causes deviation these.

Abstract Cellulose is the most abundant component of plant litter, which critical for terrestrial carbon cycling. Nonetheless, it remains unknown how global warming affects cellulose-decomposing microorganisms. Here, we carried out a 3-year litterbag experiment to examine cellulose decomposition undergoing +3°C in tallgrass prairie. Most cellulose-associated bacteria and fungi litterbags were also detected bulk soil, had higher community-level rrn copy numbers, larger genome sizes, guanine-cytosine (GC) contents than those implying growth rates. Warming stimulated soil respiration by 32.3% accelerated mass loss cellulose, concurring with increase relative abundances functional genes associated litterbags. Incorporating into an ecosystem model reduced parameter uncertainty showed that microbial biomass, activity, decomposition. Collectively, our study supports trait-centric view since or genomic traits are amenable modeling. By characterizing phylogenetically diverse yet functionally similar microorganisms their responses warming, take step toward more precise predictions dynamics under future climate scenarios.

ABSTRACT Soil microbial communities provide numerous ecosystem functions, such as nutrient cycling, decomposition, and carbon storage. However, global change, including land‐use climate changes, affects soil activity. As extreme weather events (e.g., heatwaves) tend to increase in magnitude frequency, we investigated the effects of heat stress on activity respiration) that had experienced four different long‐term intensity treatments (ranging from extensive grassland intensive organic conventional croplands) two conditions (ambient vs. predicted future climate). We hypothesized both land use would reduce respiration (H1) experimental (H2). this be less pronounced soils with a history high‐intensity (H3), higher fungal‐to‐bacterial ratio show more moderate response warming (H4). Our study showed was reduced under high (i.e., −43% between cropland) (−12% comparison ambient Moreover, increased overall (+17% per 1°C increase), while increasing strength (−25% slope reduction). In addition, biomass low‐intensity grassland) enhanced stress. These findings change may compromise well their heatwaves. particular, are able respond additional stress, heatwaves, potentially threatening critical functions driven by microbes highlighting benefits sustainable agricultural practices.

A key unresolved question in microbial ecology is how the extraordinary diversity of microbiomes emerges from interactions among their many functionally distinct populations. This process driven part by cross-feeding networks that help to structure these systems, which consumers use resources fuel metabolism, creating by-products can be used others community. Understanding effects presents a major challenge, as it creates complex interdependencies between populations hard untangle. We address this problem using tools network science develop structural community model. Using methods percolation theory, we identify feasible states for structures needs are met metabolite production across tipping points at small changes cause catastrophic collapse and abrupt declines diversity. Our results an example well-defined point ecological system provide insight into fundamental processes shaping robustness. further demonstrate considering attacks affect apply our show apparent difficulty culturing inherent property networks.
