AI Article Synopsis
- Soil organic carbon (SOC) is a significant part of the global carbon cycle, and its levels are affected by changes in land use and cover.
- The study focused on the Tarim River in China from 2000 to 2010, revealing that cultivated and shrub lands expanded, while areas of forestland, grassland, and unused land decreased significantly.
- The conversion of various land types, particularly from forestland to other uses, led to a reduction in SOC stocks, highlighting the need for eco-environmental protection in arid regions.
Article Abstract
Soil organic carbon (SOC) constitutes a large pool within the global carbon cycle. Changes in land-use/cover strongly drive variation of SOC stocks. We analyzed the changes in four types of land use/cover and their influence on SOC content, density, and regional stocks along the main channel of the Tarim River in China for 2000-2010 obtained from remotely sensed images and field surveys. The areas and structures of the land uses/covers changed greatly during this period. Specifically, the areas of cultivated, industrial and residential, and shrub land increased, particularly cultivated and shrub land. The areas of forestland, grassland, water bodies, and unused land decreased. SOC stocks in forestland, grassland and unused land decreased between 2000 and 2010. The total SOC stock for the forestland shrub land grassland and unused land was lower in 2010 than 2000. Land-use/cover conversion thus affected SOC stocks. Specifically, conversions from forestland to shrub land, forestland to grassland, forestland to unused land, grassland to shrub land, grassland to unused land, and shrub land to unused land decreased the SOC stocks. This study provides a scientific basis for eco-environmental protection in arid areas.

Trees shape the soil microbiome of a temperate agrosilvopastoral and syntropic agroforestry system.

Agroforestry systems are multifunctional land-use systems that promote soil life. Despite their large potential spatio-temporal complexity, the majority of studies that investigated soil organisms in temperate cropland agroforestry systems focused on rather non-complex systems. Here, we investigated the topsoil and subsoil microbiome of two complex and innovative alley cropping systems: an agrosilvopastoral system combining poplar trees, crops, and livestock and a syntropic agroforestry system combining 35 tree and shrub species with forage crops.

The positive relationship between species richness and area is a fundamental principle in ecology. However, this pattern deviates on small islands, where species richness either changes independently of area or increases at a slower rate-a phenomenon known as the Small-Island Effect (SIE). While the SIE has been well documented in natural ecosystem, its presence in highly fragmented and disturbed urban ecosystem remains unexplored, posing challenges for urban vegetation conservation.

Electronic address:
Air pollution is highest in winter. The high concentration of particulate matter (PM) and trace elements (TE) after the growing season is influenced by increased pollutant emissions, unfavorable meteorological conditions, and the low efficiency of air phytofiltration. Plants that can remove pollutants from the air during the growing season are leafless in autumn/winter, and therefore unable to capture PM/TE effectively.

Background: Nutrient limitation is a universal phenomenon in terrestrial ecosystems. Root and mycorrhizal are critical to plant nutrient absorption in nutrient-limited ecosystems. However, how they are modified by N and P limitations with advancing vegetation successions in karst forests remains poorly understood.

The land use/land cover in the Sudano-Sahelian area of Cameroon has been disturbed since these 3 decades resulting from the influence of anthropogenic factors. This study aimed to assess floristic diversity and the impacts of anthropogenic activities on the Pette forest massifs in the Pette Subdivision. The transect method (1000 × 20 m) was used for plant inventory, and Landsat images 5 TM (1990), 7 ETM+ (2005) and 8 OLI_TIRS (2020) were analysed to determine land cover.
