Many conservationists associate China with substantial environmental problems linked to the country's rapid economic development and the associated pollution and exploitation of its natural resources. Nonetheless, recent migrations of large parts of China's rural population into the booming cities has created vast, increasingly depopulated rural areas, in turn allowing the central government to instigate a series of measures aimed at improving the environmental conditions of rural landscapes across the country. These measures range from a strict protection of remaining mature forests to a restructuring of rural landscapes through globally unprecedented reforestation campaigns that are commonly aimed at reducing soil erosion and flooding. The potential of the resulting landscape changes to enhance biodiversity and associated ecosystem services has received limited attention to date. Here, we present results from our studies of plant, predatory ground beetle and geometrid moth assemblages and of their diversity patterns across forested and agricultural landscapes in northern and north-eastern China over the last decade. We illustrate the potential of secondary and plantation forest landscape to harbor insect and plant assemblages of similar, or even higher species richness in comparison to assemblages recorded in large mature forests remnants, and we demonstrate a strong local recruitment patterns of species assemblages in our study region. We also show that turnover across the different taxonomic groups is highly linked to climatic conditions and the wider landscape context, while cross-taxon links are generally weak. We discuss the implications of our findings for the conservation and potential enhancement of biodiversity and associated ecosystem services across the study region. ; peerReviewed

Human land use threatens global biodiversity and compromises multiple ecosystem functions critical to food production. Whether crop yield-related ecosystem services can be maintained by a few dominant species or rely on high richness remains unclear. Using a global database from 89 studies (with 1475 locations), we partition the relative importance of species richness, abundance, and dominance for pollination; biological pest control; and final yields in the context of ongoing land-use change. Pollinator and enemy richness directly supported ecosystem services in addition to and independent of abundance and dominance. Up to 50% of the negative effects of landscape simplification on ecosystem services was due to richness losses of service-providing organisms, with negative consequences for crop yields. Maintaining the biodiversity of ecosystem service providers is therefore vital to sustain the flow of key agroecosystem benefits to society.
