Ecology: Pesticides linked to bird declines

  title={Ecology: Pesticides linked to bird declines},
  author={Dave Goulson},
Decreases in bird numbers are most rapid in areas that are most heavily polluted with neonicotinoids, suggesting that the environmental damage inflicted by these insecticides may be much broader than previously thought. See Letter p.341 The use of neonicotinoid pesticides in recent decades has been linked to declines in bees and other invertebrate pollinators. Caspar Hallmann et al. present data from the Netherlands showing a correlation between declines in insectivorous farmland bird… Expand
Are neonicotinoid insecticides driving declines of widespread butterflies?
Build models of the UK population indices from 1985 to 2012 for 17 widespread butterfly species that commonly occur at farmland sites to show whether there is a causal link between neonicotinoid usage and the decline of widespread butterflies or whether it simply represents a proxy for other environmental factors associated with intensive agriculture.

Analysis of trends and agricultural drivers of farmland bird declines in North America: A review
Modifications to farmland management such as reducing pesticide inputs through integrated pest management and maintaining or restoring uncultivated field margins and native habitat could positively influence farmland birds without significantly reducing agricultural crop yields. Expand
Analysis of trends and agricultural drivers of farmland bird declines in North America : A review
Globally, agriculture has intensified during the past 50 years due to increased mechanization, changes in the timing of farming operations, grassland conversion to cropland, and increasedExpand
Feeding partridges with organic or conventional grain triggers cascading effects in life-history traits.
It is shown for the first time that ingesting low pesticide doses over a long period has long-term consequences on several major physiological pathways without inducing differential mortality, consistent with a hormetic effect, and suggested that breeding adults may show impaired fitness traits bearing population consequences through reduced breeding investment or productivity.

Potential effects of neonicotinoid insecticides on northern bobwhites
Overall, evidence of bobwhite exposure to neonicotinoid insecticides is identified, which correlates with a previous study that suggests that neonicsotinoid use may be contributing to quail decline in some ecoregions in Texas, particularly the High Plains, Rolling Plains, Gulf Coast Prairies and Marshes, South Texas Plains, and Edwards Plateau.

The environmental risks of neonicotinoid pesticides: a review of the evidence post 2013
A growing body of evidence demonstrates that persistent, low levels of neonicotinoids can have negative impacts on a wide range of free-living organisms. Expand
Potential impact of neonicotinoid use on Northern bobwhite (Colinus virginianus) in Texas: A historical analysis
It is suggested that the use of neonicotinoid insecticides may negatively affect bobwhite populations in crop-producing regions of Texas. Expand
Hindcasting the impacts of land-use changes on bird communities with species distribution models of Bird Atlas data.
The findings confirm land-use change as a key driving force for shaping bird communities in southern Quebec, together with the need to explicitly incorporate it into global change scenarios that better inform decision-makers on conservation and management. Expand
Brood size is reduced by half in birds feeding on flutriafol-treated seeds below the recommended application rate.
It is demonstrated that seed treatment with flutriafol represents a risk for granivorous birds; they also highlight a need to improve the current regulation system used for foreseeing and preventing negative impacts of Plant Protection Products on wildlife. Expand
Seasonal changes in distribution and abundance of a local Corncrake population
The need for better knowledge of Corncrake dispersal within the main European population and for the coordination of monitoring and conservation efforts is highlighted, especially in those regions where most Corncrakes breed. Expand


Declines in insectivorous birds are associated with high neonicotinoid concentrations
The hypothesis that the most widely used neonicotinoid insecticide, imidacloprid, has a negative impact on insectivorous bird populations is investigated and it is shown that, in the Netherlands, local population trends were significantly more negative in areas with higher surface-water concentrations of imidcloprid. Expand
Macro-invertebrate decline in surface water polluted with imidacloprid.
This study shows that serious concern about the far-reaching consequences of the abundant use of imidacloprid for aquatic ecosystems is justified, and uses the monitoring field data to test whether the existing three water quality norms for imidcloprid in the Netherlands are protective in real conditions.

REVIEW: An overview of the environmental risks posed by neonicotinoid insecticides
Major knowledge gaps remain, but current use of neonicotinoids is likely to be impacting on a broad range of non-target taxa including pollinators and soil and aquatic invertebrates and hence threatens a range of ecosystem services. Expand
Assessment of the environmental exposure of honeybees to particulate matter containing neonicotinoid insecticides coming from corn coated seeds.
Experimental results show that the environmental release of particles containing neonicotinoids can produce high exposure levels for bees, with lethal effects compatible with colony losses phenomena observed by beekeepers. Expand
Neonicotinoid insecticide toxicology: mechanisms of selective action.
The neonicotinoids have outstanding potency and systemic action for crop protection against piercing-sucking pests, and they are highly effective for flea control on cats and dogs. Expand
