Conclusions of the Worldwide Integrated Assessment on the risks of neonicotinoids and fipronil to biodiversity and ecosystem functioning

Large scale and partly prophylactic use of neonicotinoids and fipronil has raised concerns about the risks they pose to biodiversity, ecosystem functioning and ecosystem services. The Worldwide Integrated Assessment (WIA) presented in this special issue is the first attempt to synthesize the state of knowledge on these risks and covers over 800 peer-reviewed publications. Here, we present the m...

Contamination of the Aquatic Environment with Neonicotinoids and its Implication for Ecosystems

The widespread use of systemic neonicotinoid insecticides in agriculture results first in contamination of the soil of the treated crops, and secondly in the transfer of residues to the aquatic environment. The high toxicity of these insecticides to aquatic insects and other arthropods has been recognized, but there is little awareness of the impacts these chemicals have on aquatic environments...

Impacts of urbanization on net primary productivity in the Pearl River Delta, China

Great changes in land use/land cover from rapid urbanization have occurred in the PearlRiver Delta, China. As the primary cause of land development in the urbanization process,urban expansion has mostly occurred on land with higher NPP, significantly impacting theregional ecosystems. The primary purpose of this study was to reveal the impacts of urbanexpansion on the regional NPP. The land cove...
