Climate factors have a major influence on biodiversity patterns often used their mean values to reflect the distribution of different organisms, reducing faceted information study unit point information, situation that may affect accuracy results. However, there has been lack systematic and comprehensive discussion regional climatic indicators selection. To address this, we evaluated plant meteorological data from 88 banners counties in Inner Mongolia considering five state climate factors, heterogeneity, total resources each sampling unit. Additionally, compared analyzed advantages over determine dominant driving diversity families, genera, species. Our results showed were better than at reflecting families genera. In Mongolia, species mainly influenced by precipitation temperature heterogeneity indicators; concurrently, correlation between family genus was also higher values. The extent which explains plants increases with decreasing taxonomic rank. this expand available selection use research deepen understanding effects arid semi-arid regions. Therefore, provides new perspectives for rational accurate or environmental conservation restoration research.

The temperate grasslands in China play a vital part regulating regional carbon cycle and climate change. Net primary productivity (NPP) is crucial index that reflects ecological function of plants the sequestration capacity grassland ecosystem. Climate change can affect NPP by changing vegetation growth, but effects on China's remain unclear. Based MODIS data monthly during 2000-2020, this study explored spatiotemporal changes its response to China. We found annual over entire increased significantly 4.0 gC/m2/year from 2000 2020. showed increasing trends for all different types, with smallest increase desert steppe (2.2 gC/m2/year) largest meadow (5.4 gC/m2/year). correlation results precipitation had positive relationship grasslands. Increased summer autumn could NPP, particularly meadow. With regard temperatures, temperature, maximum decrease NPP. However, spring minimum temperature steppe.

With the escalating global climate change and frequent human activities, Inner Mongolia, as a crucial ecological barrier in Beijing-Tianjin-Hebei region, Bohai Economic Rim, even whole country, confronts many ecosystem issues. To reveal intricate interplay between natural processes, policy interventions shaping region’s landscape, we provide comprehensive analysis of quality Mongolia from 2002 to 2021. Key findings include: (1) The research uncovers an overall improvement across albeit with certain regions exhibiting pattern deterioration followed by improvement, particularly notable central part province. (2) Cropland, shrub, grassland, barren, wetland, water are decreasing, while impervious, forestland increasing. (3) Precipitation, temperature, elevation significant drivers affecting environment. Interestingly, production activities have altered conditions, factors like GDP, population density, night lighting index do not directly impact environmental significantly. This underscores among various within socioeconomic system, highlighting its complexity. (4) Based on these findings, our recommendations include strengthening monitoring management, promoting sustainable urban development, conducting public education awareness campaigns, fostering stakeholder collaboration for data sharing collective understanding. Adopting management strategies is essential resilience mitigating degradation only benefiting local but also contributing national well-being.

Climate change affects plant dynamics and functioning of terrestrial ecosystems. This study aims to investigate temporal changes in global vegetation coverage biomes during the past three decades. We compared historic annual NDVI time series (1982, 1983, 1984 1985) with recent ones (2015, 2016, 2017 2018), captured from NOAA-AVHRR satellite observations. To correct for missing data outliers, we applied Harmonic Analysis Time Series (HANTS) algorithm. The were decomposed their significant amplitude phase given periodic fluctuation, except ever green vegetation. Our findings show that average values most have increased significantly (F-value<0.01) by 0.05 ndvi units over decades, tundra, deserts xeric shrublands. highest rates harmonic components observed northern hemisphere, mainly above 30° latitude.

Arbuscular mycorrhizal fungi (AMF) have been reported to a wide distribution in terrestrial ecosystems and play vital role ecosystem functioning symbiosis with Stipa grasses. However, exactly how AMF communities the rhizosphere change are distributed along different population substituted their relationships remain unclear. Here, changes of associations between hosts dynamic differences glomalin-related soil protein (GRSP) seven species spatial substitution characteristics arid semiarid grasslands were investigated. Along populations, community structures, taxa, numbers, alpha diversity index values changed. Some taxa appeared only certain species, but there was no obvious taxon turnover. When baicalensis replaced by gobica population, GRSP tended decline, whereas carbon contribution increase. grandis krylovii had great degree network modularity exhibited simple unstable structure, while networks breviflora complex, compact, highly stable. Furthermore, succession zonal plant vegetation coverage, climate gradient facilitated differentiation structures quantities rhizospheres species. These findings present novel insights into dynamics correlated changing environments.
