In this paper, topology evolution problem is addressed for improving the network performance in wireless multi-hop networks. A novel topology model based on social inspired mechanism with energy-aware and local-world features is proposed to handle the time-varying nature of wireless multi-hop...

In 2017 summer, we observed a widespread bottom hypoxic zone at the lower estuary of the Pearl River estuary (PRE). We observed i) bacterial and AOA biomass accumulation, ii) oxygen consumption rates (respiration and nitrification) in the hypoxic zone. The potential microbial interaction of both...

The concentration of crop cultivation can be measured in terms of spatial clustering and of inequality in the distribution of the cropland area. We used official agricultural statistics at the county level (N = 2,354) for each year from 1980 to 2011 for all of China to analyse the changes in...

Повышение урожайности сельскохозяйственных культур играет решающую роль в удовлетворении растущего спроса на продовольствие в мире. Россия облада-ет...

Recognition of the importance of forests for local livelihoods, biodiversity and the climate system has spurred a growing interest in understanding the factors that drive forest-cover change. Forest transitions, the change from net deforestation to net reforestation, may follow different...

Understanding the processes of historical land-use change is crucial to the research of global environmental sustainability. Here we examine and attempt to disentangle the evolutionary interactions between land-use change and its underlying causes through a historical lens. We compiled and...

Massive and rapid urbanization has led to population loss in rural areas, particularly in emerging and developing countries like China. As a result, houses in rural areas become vacant, and the house prices in cities, at the same time, skyrocket. While the research on the vacant farmhouses...

Grazing leads to the reduction of biomass and plays a critical role in land degradation in arid and semiarid lands. However, the indirect effects of grazing on the ecosystem, e.g., the effect on seed dispersal, have not been well understood. In this study, we built an agent-based model (ABM) to...
