“…Wetlands are well known as the kidney of the earth with abundant biological resources and ecological functions such as purifying the water source, mitigating floods and droughts, and regulating regional microclimate (Chakraborty et al., 2023; Ye et al., 2022). In recent years, increasing numbers of reports have confirmed that AM fungi also exist widely in wetland habitats and can colonize the roots of various hygrophytes to form AM symbiotic structure (Xu et al., 2016; Yan et al., 2008).…”

The hydrological regime is considered to be the major factor that affects the distribution of arbuscular mycorrhiza (AM) fungi in wetlands. We aimed to investigate the responses of AM fungal community to different hydrological gradients. Illumina Miseq sequencing technology was used to study the AM fungal community structure in roots and rhizosphere soils of Phragmites australis in different moisture areas (dry area, alternating wet and dry area, and flooded area) in Mengjin Yellow River wetland. The rhizosphere soils and roots hosted different AM fungal communities. In roots, the AM fungal colonization and Chao1 richness in dry area were significantly higher than that in alternating wet and dry area and flooded area, but the community composition did not vary clearly under different water conditions. In rhizosphere soils, the Chao1 richness of AM fungi in flooded area was significantly higher than that in alternating wet and dry area and dry area, and the AM fungal community structure obviously differed across different areas. The redundancy analyses indicated that changes in the AM fungal community in soils were associated with altered soil properties, and the abundance of the dominant genus Glomus was mostly positively correlated with alkali‐hydrolyzable nitrogen in soils. This study helps us to understand the responses of AM fungal community to hydrological gradients in wetlands.

Wetlands play an important role in supporting biodiversity conservation and helping sustainable development. Time series wetland classification requires a series of sample sets acquired at different times. To meet this need, we proposed a method for automatically producing global wetland samples based on 13 global and regional wetland-related datasets and millions of images from Landsat 8 Operational Land Imager (OLI), Moderate Resolution Imaging Spectroradiometer (MODIS), Sentinel-1 Synthetic Aperture Radar (SAR) Ground Range Detected (GRD), and Sentinel-2 Multispectral Instrument (MSI) sensors. On this basis, we analyzed the classification capabilities of wetland features in the above four sensors and obtained a multi-sensor, full spectral band, multi-index wetland classification feature dataset at a global scale. The analysis results show that the shortwave infrared band (SWIR) and Land Surface Water Index (LSWI) can distinguish non-wetlands from other land cover types well, while the Modified Normalized Difference Water Index (MNDWI), Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI), and thermal infrared bands (TIR) could help distinguish water bodies and wetlands. C bands in Sentinel 1 perform well in identifying water bodies, but the ability to distinguish wetlands is limited. The mapping coefficients of the corresponding spectral bands and indexes between Sentinel-2, MODIS data, and Landsat were obtained to help realize the collaborative use of multi-sensor image data. This paper could provide guidance for large-scale wetland classification and mapping research.
