Abstract Drought has broad and deep impacts on vegetation. Studies the effects of drought vegetation have been conducted over years. Recently, cumulative effect is recognized as another key factor affecting plant growth. However, global‐scale studies this phenomenon are still lacking. Thus, based new satellite gross primary productivity (GPP) multi‐temporal scale Standardized Precipitation Evapotranspiration Index data sets, we explored duration (CED) global GPP analyzed its variability across elevations climatic zones. The main findings were follows: (1) was widespread, with an average CED 4.89 months. (2) varied among types. Specifically, grasslands showed longest duration, value 5.28 months, followed by shrublands (5.09 months), wetlands (5.03 croplands (4.85 savannas (4.58 forestlands (4.57 months). (3) changes climate conditions. It decreased decrease precipitation in driest month (P dry ) mean annual tropical arid zones, respectively. In both temperate cold shorter areas winter than that summer. increased air temperature zones increase summer (4) With increasing elevation, a pattern (0–3000 m), then decreasing (3000–5000 again (>5000 m). Our highlight heterogeneity GPP, owing to differences types, long‐term hydrothermal conditions, etc. results could deepen our understanding

Terrestrial organisms and ecosystems are being exposed to new rapidly changing combinations of solar UV radiation other environmental factors because ongoing changes in stratospheric ozone climate. In this Quadrennial Assessment, we examine the interactive effects ozone, climate on terrestrial biogeochemical cycles context Montreal Protocol. We specifically assess organisms, agriculture food supply, biodiversity, ecosystem services feedbacks system. Emphasis is placed role extreme events altering exposure potential biodiversity. also address responses plants increased temporal variability radiation, change (e.g. drought, temperature) crops, driving breakdown organic matter from dead plant material (i.e. litter) biocides (pesticides herbicides). Our assessment indicates that interact various ways affect structure function ecosystems, by protecting layer, Protocol continues play a vital maintaining healthy, diverse land sustain life Earth.

Geographical, climatic, and soil factors control the altitudinal pattern of rhizosphere microbial diversity and its driving effect on root zone soil multifunctionality in mountain ecosystems

The Science of The Total Environment, Год журнала: 2023, Номер 904, С. 166932 - 166932

Shifts in rhizosphere soil microorganisms of dominant plants' response to climate change profoundly impact mountain ecosystem multifunctionality; relatively little is known about the relationship between them and how they depend on long-term environmental drivers. Here, we conducted analyses microbial altitudinal pattern, community assembly, co-occurrence network 6 plants six typical vegetation zones ranging from 1350 2900 m (a.s.l.) Helan Mountains by absolute quantitative sequencing technology, finally related microbiomes root zone multifunctionality ('soil multifunctionality' hereafter), dependence was explored. It found that pattern bacterial fungal diversities differed significantly. Higher more potential interactions Stipa breviflora Carex coninux were at lowest highest altitudes. Bacterial α diversity, identity some taxa, had significant positive or negative effects multifunctionality. The effect sizes diversity greater than those effects. These results indicated balance microbes determines As number phylum level increases, there will be a net gain Our study reveals geographical climatic factors can directly modulate properties thereby affecting driving multifunctionality, points rather fungi being strongly associated with This work has important ecological implications for predicting multiple environment-plant-soil-microorganisms ecosystems respond future change.

Climate change is causing shifts in the habitat, distribution, ecology, and phenology of Himalayan plants. These changes are predicted to continue, jeopardizing survival medicinal plant species local livelihoods that rely on them. We analyzed present future diversity distribution influenced by different climate scenarios, calculated climatic niche using ensemble modeling (eSDM). compiled 1041 (N) geospatial data seven high-value Nepal: Aconitum spicatum (n = 100), Allium wallichii 151), Bergenia ciliata 48), Nardostachys jatamansi 121), Neopicrorhiza scrophulariiflora 94), Paris polyphylla 310) Valeriana 217) including over 85 % from field surveys rest literature online database. used bioclimatic variables Models for Interdisciplinary Research (MIROC) version MIROC6, selected Shared Socioeconomic Pathways (SSP)2-4.5 SSP5-8.5 year 2050 2070 modeling. found elevation, mean diurnal annual temperature ranges (BIO2 BIO7), precipitation warmest coldest quarters (BIO18 BIO19) be most high weight cofactors projecting potential plants Nepal.
