Grassland ecosystems are being invaded by shrubs around the world, especially in temperate semi-arid regions of the Northern Hemisphere, under the influences of climate change and human activities.

Cold stress at the booting stage leads to lower seed setting rate and seriously threatens the production and quality of rice.

Soybean cyst nematode (SCN, Heterodera glycines Ichinohe), is a devastating pathogen in soybean. The infective juveniles of nematodes can use phytochemical signals (semiochemicals) released into the rhizosphere as important cues for host seeking, host locating and penetrating.

A research group led by Prof. Wang Zongming from the Northeast Institute of Geography and Agroecology (IGA) of the Chinese Academy of Sciences has developed an object-oriented method to obtain the annual 10-m-spatial-resolution national coastal aquaculture pond dataset of China between 2016 and 2021 (China_CAP), with an overall classification accuracy of more than 90%. The method integrated superpixels image…

Soybean cyst nematode (SCN) is one of the devastating diseases in soybean worldwide. Host-plant resistance is the most economical and effective method to control SCN disease.

Soil aggregates are the basic units of soil structure and serve as a reservoir for soil carbon, playing a crucial role in the carbon cycle of ecosystems. The pore characteristics of soil aggregates influence the mineralization of soil organic carbon. However, research on the mechanisms of soil organic carbon sequestration at the aggregate level in Mollisols is limited.

As the highest plateau in the world, the Qinghai-Tibet Plateau has large areas of marshes, which have important effects on the biogeochemical cycle and carbon balance. As an important functional parameter of marsh wetland ecosystem, net primary productivity (NPP) of vegetation is an important indicator to measure the carbon sequestration potential of marsh wetland.

Plastic film mulching has been applied globally in various agricultural settings and inevitably disintegrates into microplastics (MPs, which are less than 5 mm in size) due to a series of natural and artificial forces. However, the effects of MPs on the dynamics of soil microbial communities and network patterns are not fully understood.

Long-term use of cropland and cropland reclamation cause decreasing trend in soil organic carbon (SOC) stock. However, studies on effects of crop reclamation on SOC changes are rare.

Freshwater ecosystems and their key component freshwater plants together provide a myriad of key ecosystem services to our society. Yet, global climate change is exerting unprecedented forces on freshwater plants and their ecosystems.
