A large number of individual studies and meta-analyses have shown that microplastics (MPs) affect soil ecosystems. However, the effects different concentrations types MPs on ecosystem are still unclear. Here, a comprehensive meta-analysis was performed to examine responses 19 variables, associated with properties, microbes, enzymes, fauna, MPs, based 114 peer-reviewed studies. The results showed addition significantly reduced organic carbon (SOC), total nitrogen (TN), NH4+-N, pH, diversity bacteria, increased dissolved (DOC), fungi enzyme activities, especially enzymes related biogeochemical cycle. We further discussed exerted negative including survival, growth, reproduction, concentration rather than type, biggest driving factor causing toxicity affecting animals. More importantly, were main DOC, TN, NO3--N, phosphorus (TP), available (AP), fungi, whereas factors reflected in SOC, activities. This study aimed evaluate response ecosystems largest for MPs.

Global climate warming and shifts in rainfall patterns are expected to trigger increases the frequency magnitude of drought and/or waterlogging stress plants. To cope with water stress, plants develop diverse tactics. However, adoption capability mechanism vary depending upon plant species identity as well duration intensity. The objectives this study were evaluate species-dependent responses alpine herbaceous stress. Nine subjected different stresses (including moderate waterlogging) pot culture using a randomized complete block design three replications for each treatment. We hypothesized that would negatively impact growth metabolism. found considerable interspecies differences morphological, physiological, biochemical when exposed same regime. In addition, we observed pronounced interactive effects regime on height, root length, root/shoot ratio, biomass, contents chlorophyll a, b, (a+b), carotenoids, malondialdehyde, soluble sugar, betaine, protein proline, implying respond differently. Our findings may cast new light ecological restoration grasslands wetlands Qinghai-Tibetan Plateau by helping select stress-tolerant species.

Abstract Global warming has significantly affected terrestrial ecosystems. Biomass and C:N:P stoichiometry of plants soil is crucial for enhancing plant productivity, improving human nutrition, regulating biogeochemical cycles. However, the effect on biomass different components (plant, leaf, stem, root, litter, soil, microbial biomass) in various ecosystems remains uncertain. We conducted a comprehensive meta‐analysis to investigate global patterns responses warming, as well interaction relationships based 1399 paired observations from 105 studies. Results indicated that had significant impact aspects growth, including an increase (+16.55%), C:N ratio (+4.15%), leaf (+16.78%), stem (+23.65%), root (+22.00%), litter (+9.54%) (+5.64%). it also decreased C:P (−23.34%), (−12.88%), N:P (−14.43%) (−16.33%). The magnitude was primary drivers changes stoichiometry. By establishing general response curves ratios with increasing temperature, we demonstrated plant, shifted negative positive, whereas changed positive temperature increased. Additionally, ratio, biomass, negative, effects N:P, C:P, ratios, temperature. Our research can help assess productivity optimize ecosystem precisely context warming.

Alpine grassland is one of the most fragile and sensitive ecosystems, it serves as a crucial ecological security barrier on Tibetan Plateau. Due to combined influence climate change human activities, degradation alpine in Gannan Prefecture has been increasing recent years, causing increases risk (ER) leading ecosystem facing unprecedented challenges. In this context, particularly construct potential damage index (PGDI) assessment framework that can be used effectively characterize ecosystem. This study comprehensively uses multi-source data PGDI based resilience index, landscape ER grass–livestock balance index. Thereafter, we proposed feasible for assessing comprehensive analyzed responsive relationship between services (ESs) grassland. There are four findings. The first from 2000–2020 had low distribution southeast high trend northwest, with medium (29.27%) lower (27.62%) dominating. high-risk area accounted 4.58% was mainly Lintan County, border Diebu Zhuoni Counties, eastern part Xiahe southwest Hezuo. Second, ESs showed pattern northwest southeast. only 9.30% studied were distributed west Maqu County central County. Third, Moran’s values 2000, 2005, 2010, 2015, 2020 −0.246, −0.429, −0.348, −0.320, −0.285, respectively, thereby indicating significant negative spatial autocorrelation all aspects. Fourth, caused by action multiple factors. differences driving factors affect ER. Landscape dominant factor affecting ER, q greater than 0.25, followed DEM NDVI. addition, interaction diversity NDVI greatest impact Overall, offers new methodological quantification grasslands.

The alpine steppe has an important place in ecosystems, and its distribution pattern is strongly influenced by climate change. In this study, we used “biomod2” “FragStats 4.2” to calculate the migration trends habitat fragmentation of three S. purpurea steppes on western Tibetan Plateau. results study show that Stipa purpurea-Ceratoides compacta steppe, purpurea-Carex moorcroftii montis-everestii are climate, while other variables have less impact. Their main influence factors annual precipitation (Bio12), warmest quarter (Bio18), coldest (Bio19), respectively. effects carbon emissions suitable habitats all significant future scenarios. Continued increases will lead a continuous reduction their areas. These communities bounded 33° N. South boundary, mountain ranges tendency migrate higher elevations southward direction. North northward Climate change reduces community aggregation, leading gradual fragmentation. findings provide scientific basis for conservation Plateau, thereby contributing improvement ecosystem stability species diversity.
