Large herbivore communities are changing globally, with populations of wild herbivores generally declining while domestic increasing, influencing ecosystem function along the impacts climate change. Manipulative experiments have rarely captured interaction between patterns large assemblage change and climatic conditions. This may affect functional traits diversity herbaceous communities; this requires investigation, as these metrics been useful proxies for function. We used a exclosure experiment replicated topo-climatic gradient to explore on community-level plant understories. Our findings demonstrate interacting effects assemblages climate. found shift from drought-tolerant drought-avoidant increasing aridity, specifically regard leaf area specific area. also determined that community responses grazing changed an avoidance strategy at drier sites more herbivore-tolerant wetter sites. observed can sometimes counteract those Finally, we cattle differ in magnitude direction diversity.

Abstract The relative importance of intraspecific trait variation ( r ITV) for functional diversity (FD) in plant communities is increasingly apparent, but the influence abiotic factors on balance between and interspecific effects contrasting environments uncertain. Drawing a novel conceptual analytic framework, we quantified ITV as ratio FD associated with between‐population Intra _FD) Inter due to species turnover across sites. We predicted that would increase environmental harshness result decreasing concomitant increases ITV. empirically tested this prediction comparison five traits (mature height, SLA, leaf dry matter content foliar concentrations nitrogen phosphorus (P)) characterizing Tibetan alpine meadow from regimes. found sites: (a) all increased not only through _FD also increasing _FD; (b) were mostly attributable declines soil resources, especially P, lower P significantly higher most traits; (c) although neither nor was impacted by richness any traits, SLA low richness. Taken together, these results support our hypothesis significance harshness. Moreover, meadows studied, opposing responses along gradient availability appear act buffering mechanism stabilizing structure deficient soils.

Abstract Understanding how plant nutrient acquisition strategies respond to grazing at the community level is critical understanding ecosystem structure and functioning in grasslands. However, few studies have simultaneously compared difference above‐ground (leaf) below‐ground (root) nutrient‐acquisition response long‐term grazing, especially regional scale. Here, we measured a set of leaf fine‐root traits that correspond fast‐slow economic spectrum 10 experimental sites from paired grazed ungrazed grasslands across soil gradient covering three major types northern China. We found patterns variations were consistent with both root for non‐grazed plots. Grazing had minor effect on community‐level but strongly influenced strategies.

Abstract The Qinghai‐Tibetan Plateau (QTP) is the most expansive area of alpine grasslands worldwide, which have been grazed for thousands years. Distinct environmental conditions render QTP vulnerable to disturbances. Intensified grazing in has led its degradation recent decades. However, effects on grassland production, soil carbon, and nitrogen contents, their relationships factors influencing yet be determined. In this study, we evaluated effect by using a hierarchical meta‐analysis, explored relation response variables structural equation modeling. all, significantly decreased aboveground biomass (−38%), total (TB) (−14%), litter (−63%), organic carbon (SOC) (−20%), (TN) (−15%). root shoot ratio was increased (75%). Grazing intensity exerted significant effects, mean annual temperature altitude influenced responses certain degree. Specifically, ratio, can affect SOC TN, higher grasslands. Our findings elucidated patterns, specialties, relationships, grasslands, need considered development process‐based models sustainable use future.

Resources can affect plant productivity and biodiversity simultaneously thus are key drivers of their relationships in addition to plant-plant interactions. However, most previous studies only focused on a single resource while neglecting the nature multidimensionality. Here we integrated four essential resources for growth into metric diversity (RD) investigate its effects productivity-biodiversity relationship (PBR) across Chinese grasslands. Results showed that habitats differing RD have different PBRs-positive low-resource habitats, but neutral medium- high-resource ones-while collectively, weak positive PBR was observed. when excluding direct biodiversity, became negative, which leads unimodal instead along gradient. By integrating changing interactions unified framework with gradient, our work contributes uncovering underlying mechanisms inconsistent PBRs at large scales.
