Abstract The warming of terrestrial high‐latitude ecosystems, while increasing, will likely be asymmetric across seasons—where winter non‐growing seasons warm more than summer‐growing seasons. Asymmetric in temperature‐sensitive ecosystems may delay spring phenological events by reducing the opportunity that a plants’ chilling requirement is met. Similarly, symmetric can advance phenology. To explore impact on plant phenology, we applied year‐round and treatment to our experimental plots....
Abstract Global warming and changes in precipitation are altering the phenology of plants that significantly impact functioning services ecosystems. Although a number studies have addressed responses plant to altered individually, their interactions can alter differently than either does independently. To explore how between global change drivers alpine ecosystems, we conducted factorial experiment manipulating (ambient +2°C) (50% decrease, control, 50% increase) simultaneously an meadow on...
The biogeochemical niche (BN) hypothesis posits that each species has a specific elemental composition. However, the BN of roots and its interaction with leaf have largely been neglected until now across diverse environmental conditions. We investigated relationships between compositions leaves roots, phylogeny, variables, as well connection root BN. analyzed concentrations carbon, nitrogen, phosphorus, potassium, calcium, magnesium in 12 394 individuals from 1238 species. Consistent...
Abstract Experimental warming in situ suggests that could lead to a loss of biodiversity. However, species remain and experience climate change will interact with tracking change, which also affect patterns The relative contribution gains losses net changes richness is still unclear. We use transplanted plant communities test the hypothesis both ecological influence how responds change. Three intact alpine were reciprocally create scenarios experienced warmer wetter conditions (transferred...
Predicting the potential influences of climate change on richness and distribution is essential for protection endangered species. Most orchid species are narrowly distributed in specific habitats very vulnerable to habitat disturbance, especially Qinghai-Tibetan Plateau (QTP). In this study, we simulated 17 QTP using MaxEnt model based shared socioeconomic pathways scenarios (SSPs) 2050s 2070s. The results showed that aspect, annual precipitation, elevation, mean temperature driest quarter,...
Abstract Climatic warming has advanced the spring phenology of plants and disrupted alignment with weather patterns. Such misalignments can cause problems as extreme events become more frequent thus impact survival, growth reproduction plants. To prevent freezing within their cells during growing season, adopt a supercooling strategy. However, event severity seasonal timing may plant’s recovery after event. We conducted experiments to investigate how four different severities impacted points...
Background and aims Nitrogen (N) enrichment usually weakens the stabilizing effect of biodiversity on productivity. However, previous studies focused plant species richness thus largely ignored potential contributions functional traits to stability, even though evidence is increasing that are stronger predictors than ecosystem functions. Methods We conducted a common garden experiment manipulating N addition levels quantify effects relations between trait identity diversity underpinning...
Global warming is one of the most pressing environmental issues today. Our study aimed to investigate how affected plant and soil nematode communities in alpine meadows on Qinghai−Tibetan Plateau over past seven years. An artificial experiment with different gradients was conducted from 2011 2018, including temperature increases 0 °C (CK), 0.53 (A), 1.15 (B), 2.07 (C), 2.17 (D), respectively. Cyperaceae plants were shown be eliminated by increasing temperature, community composition tended...
Few studies have focused on the response of plant community phenology to temperature change using manipulative experiments. A lack understanding whether responses reproductive and vegetative phenological sequences warming cooling are asymmetrical or symmetrical limits our capacity predict under cooling. reciprocal transplant experiment was conducted for 3 years evaluate patterns sensitivities (transferred downward) upward) along four elevations Tibetan Plateau. We found that flowering stages...
This study presents an efficient strategy for large‐scale preparation of low polarity gingerols directly from ginger crude extract by high‐speed countercurrent chromatography with different rotation mode. The ultrasonic‐assisted extraction conditions were optimized response surface methodology and the results showed major could be well enriched under conditions. Then without any pretreatment was separated mode using n‐hexane/ethyl acetate/methanol/water (6:4:6:4, v/v/v/v) as solvent system....
Intact Tibetan meadows provide significant defense against soil-borne pathogen dispersal. However, dramatic meadow degradation has been observed due to climate change and pika damage, but their impacts on pathogens are still unclear. With approximately 40% of the world’s population living in Plateau its downstream watersheds, this lack knowledge should be great concern. Here, we used Illumina amplicon sequencing characterize changes potential human, domestic animal, plant, zoonotic bacterial...
Abstract Questions Traditional pastoralists attribute high numbers of plateau pikas ( Ochotona curzoniae ) to impoverished soils that favor more and better forage for pika, suggesting a bottom‐up control pika density. Conversely, government policies focus on excessive this small mammalian herbivore as the primary top‐down cause degradation in Tibetan rangeland. Despite concerted campaigns reduce abundance recent decades, sustainability rangelands remains uncertain. Location Alpine meadows...
Alpine plants possess unique traits to adapt alpine environments. Whether leaf trait relationships of can be captured by the two dimensions organ size and resource economics is unknown. We hypothesized that, beyond economics, non-structured carbohydrates (NSC) would reflect a dimension cold-tolerance in plants. To test this hypothesis, we measured 12 critical construction growth 143 species across 7 sites ranging from steppes meadows along an environmental gradient on Tibetan Plateau....
Climate warming is the dominant form of grassland disturbance. In this study, we conducted a seven-year artificial experiment with different gradients, temperature increases 0°C (CK), 0.53°C (A), 1.15°C (B), 2.07°C (C), and 2.17°C (D), respectively, to explore response plant soil nematode abundance, diversity, community structure their mutual synergy changes. Increased was shown eliminate cyperaceae plants, composition tended cluster separately under gradients. The relative abundance...
1. Alpine plants possess unique traits owing to their adaptation alpine environments. However, it remains unknown whether leaf trait relationships of can be captured by the two general dimensions organ size and resource economics. 2. We hypothesized that, beyond economics, non-structured carbohydrates (NSCs) would reflect an important dimension cold-tolerance in plants. 3. measured 12 critical construction, growth, stress resistance 225 site species, ranging from 7 sites along steppes...
