Neonicotinoids have been used to protect crops and animals from insect pests since the
1990s, but there are concerns regarding their adverse effects on nontarget organisms …

For decades, we have observed a major biodiversity crisis impacting all taxa. Avian species
have been particularly well monitored over the long term, documenting their declines. In …

Raptors (birds of prey and owls) have been widely used as suitable bioindicators of
environmental pollution. They occupy the highest trophic positions in their food chains and …

Usage of neonicotinoids is common in all agricultural regions of the world but data on
environmental contamination in tropical regions is scarce. We conducted a survey of five …

Abstract Knowledge gaps regarding the potential role of pesticides in the loss of agricultural
biodiversity worldwide and mixture-related issues hamper proper risk assessment of …

Neonicotinoids (neonics) are the most widely used insecticides worldwide and are
considered to be of low risk to non-target organisms such as vertebrates. Further, they are …

Biomonitoring in raptors can be used to study long-term and large-scale changes in
environmental pollution. In Europe, such monitoring is needed to assess environmental risks …

Intensification of agricultural practices has resulted in a substantial decline of Europe's
farmland bird populations. Together with increasing urbanisation, chemical pollution arising …

Imidacloprid (IMI) is a typical neonicotinoid with the largest usage in agricultural orchards in
China. The long-term repeated use and the lack of proper protective measures may result in …

To examine the spatial, and temporal variation and potential sources of pesticide
