Global climate change is predicted to have large impacts on the phenology and reproduction of alpine plants, which will important implications for plant demography community interactions, trophic dynamics, ecosystem energy balance, human livelihoods. In this article we report results a 3-year, fully factorial experimental study exploring how warming, snow addition, their combination affect reproductive phenology, effort, success four species belonging three different life forms in semiarid,...
Abstract Phenology studies the cycle of events in nature that are initiated and driven by an annually recurring environment. Plant phenology is expected to be one most sensitive easily observable natural indicators climate change. On Tibetan Plateau (TP), accelerated warming since mid-1980s has resulted significant environmental changes. These new conditions accompanied phenological changes characterized considerable spatiotemporal heterogeneity. Satellite remote sensing observed widespread...
Alpine meadows on the Tibetan Plateau comprise largest alpine ecosystem in world and provide critical services, including forage production carbon sequestration, which people depend from local to global scales. However, provision of these services may be threatened by climate warming combined with land use policies that are altering if how pastoralists can continue graze livestock, dominant livelihood practice this region for millennia. We synthesized findings a yak grazing experiment...
Abstract Organisms’ life cycles consist of hierarchical stages, from a single phenological stage (for example, flowering within season), to vegetative and reproductive phases, the total lifespan individual. Yet events are typically studied in isolation, limiting our understanding history responses climate change. Here, we reciprocally transfer plant communities along an elevation gradient investigate plastic changes duration sequential for six alpine species. We show that prolonged leads...
Extended growing season lengths under climatic warming suggest increased time for plant growth. However, research has focused on impacts to the timing or duration of distinct phenological events. Comparatively little is known about relative allocation events, example, proportion dedicated leaf growth versus senescence. We use multiple satellite and ground-based observations show that, despite recent climate change during 2001 2020, ratio allocated vegetation green-up over senescence remained...
Plant community properties such as species richness, evenness, and composition vary along environmental gradients. Arid semi-arid ecosystems, the central Tibetan Plateau, are thought to be sensitive changes in temperature water availability, also influenced by a long history of herbivore grazing. We used linear mixed effect models Canonical Correspondence Analysis explore how plant varied gradients elevation, soil moisture, grazing intensity, solar radiation, ground surface roughness (ground...
Abstract High altitude areas play an essential role in the global climate system, and their fragile ecosystems sensitively respond to change human activities. An improved understanding of influences multiple factors on spatiotemporal dynamics vegetation is needed. This study aimed understand further impacts climate, geography, disentangle contributions humans changes using MOD13Q1 enhanced index (EVI, 2000–2019). Greening was detected for 70% Tibetan Plateau under increased warming wetting...
Abstract Aim Chronic directional climate changes in temperature and precipitation are predicted to increase the frequency of extreme climatic events (ECEs); however, their co‐occurring effects on temporal stability community productivity (i.e. ANPP stability) still unclear. Here, we evaluate whether increased ECEs reduces stability, how it modulates chronic factors natural grassland. Location Twenty‐two sites Asia 14 North America. Time period 1980s–2010s. Major taxa studied Herbaceous...
The timing of the fruit-set stage (i.e., start and end fruit set) is crucial in a plant's life cycle, but its response to temperature change still unclear. We investigated seven phenological events, including dates during 3 yr for six alpine plants transplanted warmer (approximately +3.5°C soils) cooler -3.5°C locations along an altitudinal gradient Tibetan area. found that remained relatively stable under both warming cooling 3-yr transplant experiment. Three earlier events (emergence first...
Abstract Our ability to predict how temperature modifies phenology at the community scale is limited by our lack of understanding responses functional groups flowering plants. These differ among species with different life histories. We performed a reciprocal transplant experiment along four elevation gradients (e.g., 3,200, 3,400, 3,600 and 3,800 m) investigate effects warming (transferred downward) cooling upward) on plant (FFGs) phenological sequences (i.e., seven events). Warming...
Abstract Changes in labile carbon (LC) pools and microbial communities are the primary factors controlling soil heterotrophic respiration ( R h ) warming experiments. Warming is expected to initially increase but studies show this may not be continuous or sustained. Specifically, LC microbiome have been shown contribute effect of extended on . However, their relative contribution unclear gap knowledge causes considerable uncertainty prediction cycle feedbacks climate change. In study, we...
Abstract Changes in day (maximum temperature, T MAX ) and night temperature (minimum MIN the preseason (e.g., winter spring) may have opposite effects on early phenophases leafing flowering) due to changing requirements of chilling accumulations ( CAC heating HAC ), which could cause advance, delay or no change phenophases. However, their relative phenology are largely unexplored, especially Tibetan Plateau. Here, observations were performed using a warming cooling experiment situ through...
Changes in ecological processes over time ambient treatments are often larger than the responses to manipulative climate change experiments. However, impacts of human-driven environmental changes on stability natural grasslands have been typically assessed by comparing differences between plots and reference plots. Little is known about whether or how regulates effects their underlying mechanisms. We collected two datasets, one a 36-year long-term observational dataset from 1983 2018, other...
Soil heterotrophic respiration (Rh ) refers to the flux of CO2 released from soil atmosphere as a result organic matter decomposition by microbes and fauna. As one major fluxes in global carbon cycle, large uncertainties still exist estimation Rh , which further limits our current understanding accumulation soils. Here, we applied Random Forest algorithm create data set linking 761 field observations with both abiotic biotic predictors. We estimated that was 48.8 ± 0.9 Pg C year-1 for...
Temperature on the Tibetan Plateau (TP) is rising at a rate higher than global average, and frequency of extreme climate events predicted to increase, making TP region critical importance for understanding consequences change ecosystems its feedbacks. The hosts largest alpine pastoral ecosystem in world: Kobresia grasslands, dominated by sedge species pygmaea. These store most terrestrial carbon (C) plateau, primarily felty root mat. With continuous warming, captured grasslands may become...
Abstract Isolated individual processes of ecosystem carbon (C) cycles have largely shaped our understanding C cycle under environmental change. Yet, in reality, are inter-related and hierarchical. How these respond to warming grazing has rarely been investigated a single manipulative experiment. Moreover, biodiversity loss is major driver change change, but whether responses mechanistically linked remains unclear. Here, we performed 5-year field with seasonal experiment an alpine meadow on...
