“…Direct exposure is a likely phenomenon both because most ASs applied in the fields during the breeding season are sprayed (Millot et al 2015 ) and because the grey partridge is a terrestrial bird that mainly lives and nests in crops (Bro et al 2013 ). However, whether direct exposure is an important route of egg contamination is an open question.…”

“…Such an origin in our study may be plausible given that (i) DDT/isomers were detected in clutches of partridges living in a site where strawberries, legumes and wine are produced and (ii) its use as an acaricide on strawberries, beans and grapes was banned in France in late March 2010 (EPHY database, accessed September 2015). Although this AS was not listed in the course of our study, we cannot exclude that it has been used by some farmers that did not participate to the work (see Bro et al 2015 ; Millot et al 2015 ).…”

“…We performed residue analyses on 52 clutches collected on 12 sites located in intensively cultivated farmlands in north-central France (Bro et al 2015 ; Millot et al 2015 ). These clutches corresponded to 645 eggs laid, of which 38.8 % hatched.…”

“…Intoxication can then lead to death or to sublethal behavioural or immune disorders that can favour the death (cf. Garg et al 2004 ; Lopez-Antia et al 2013 , 2015 ; Millot et al 2015 ; and ref therein), as well as reproductive disorders such as anomalies in courtship behaviour (Fernie et al 2003 ; Ottinger et al 2008 ); anatomical anomalies of gonads (Bauer 1985 ); decrease in chick production rate through reduced clutch size, clutch abandonment, reduced fertility, teratogenicity or other effects such as eggshell thinning (Fernie et al 2003 ; Kamata et al 2010 ; Kitulagodage et al 2011 ; Lopez-Antia et al 2015 ; Maci and Arias 1987 ; Mendenhall et al 1983 ; Mineau 2005 ); reduced chick survival and poor chick condition (Bhaskar et al 2012 ; Kitulagodage et al 2011 ; Lopez-Antia et al 2015 ; Mineau 2005 ; Nitu et al 2012 ; Uggini et al 2012 ). Intergenerational effects are also observed (Bauer 1985 ; Fernie et al 2003 ).…”

The contamination of the eggs of farmland birds by currently used plant protection products (PPPs) is poorly documented despite a potential to adversely impact their breeding performance. In this context, 139 eggs of 52 grey partridge Perdix perdix clutches, collected on 12 intensively cultivated farmlands in France in 2010–2011, were analysed. Given the great diversity of PPPs applied on agricultural fields, we used exploratory GC/MS-MS and LC/MS-MS screenings measuring ca. 500 compounds. The limit of quantification was 0.01 mg/kg, a statutory reference. A total of 15 different compounds were detected in 24 clutches. Nine of them have been used by farmers to protect crops against fungi (difenoconazole, tebuconazole, cyproconazole, fenpropidin and prochloraz), insects (lambda-cyhalothrin and thiamethoxam/clothianidin) and weeds (bromoxynil and diflufenican). Some old PPPs were also detected (fipronil(+sulfone), HCH(α,β,δ isomers), diphenylamine, heptachlor(+epoxyde), DDT(Σisomers)), as well as PCBs(153, 180). Concentrations ranged between <0.01 and 0.05 mg/kg but reached 0.067 (thiamethoxam/clothianidin), 0.11 (heptachlor + epoxyde) and 0.34 (fenpropidin) mg/kg in some cases. These results testify an actual exposure of females and/or their eggs to PPPs in operational conditions, as well as to organochlorine pollutants or their residues, banned in France since several years if not several decades, that persistently contaminate the environment.Routes of exposure, probability to detect a contamination in the eggs, and effects on egg/embryo characteristics are discussed with regard to the scientific literature.Electronic supplementary materialThe online version of this article (doi:10.1007/s11356-016-6093-7) contains supplementary material, which is available to authorized users.

“…Such a daily dose of imidacloprid exceeds that which causes sublethal effects in red-legged partridges, while the dose of fipronil exceeds the species LD50. Millot et al (2015) reported that about 10% of the grey partridges found in their study fields that were exposed to thiacloprid, subsequently died, even though few direct impacts of other pesticides were detected. Finally, Millot et al (2017) suggested that in France, mortality due to poisoning by imidacloprid-treated seeds was at least likely in 70% of wildlife mortality incidents reported during 1994-2014.…”

New information on the lethal and sublethal effects of neonicotinoids and fipronil on organisms is presented in this review, complementing the previous Worldwide Integrated Assessment (WIA) in 2015. The high toxicity of these systemic insecticides to invertebrates has been confirmed and expanded to include more species and compounds. Most of the recent research has focused on bees and the sublethal and ecological impacts these insecticides have on pollinators. Toxic effects on other invertebrate taxa also covered predatory and parasitoid natural enemies and aquatic arthropods. Little new information has been gathered on soil organisms. The impact on marine and coastal ecosystems is still largely uncharted. The chronic lethality of neonicotinoids to insects and crustaceans, and the strengthened evidence that these chemicals also impair the immune system and reproduction, highlights the dangers of this particular insecticidal class (neonicotinoids and fipronil), with the potential to greatly decrease populations of arthropods in both terrestrial and aquatic environments. Sublethal effects on fish, reptiles, frogs, birds, and mammals are also reported, showing a better understanding of the mechanisms of toxicity of these insecticides in vertebrates and their deleterious impacts on growth, reproduction, and neurobehaviour of most of the species tested. This review concludes with a summary of impacts on the ecosystem services and functioning, particularly on pollination, soil biota, and aquatic invertebrate communities, thus reinforcing the previous WIA conclusions .

How to promote multifunctionality of vegetated strips in arable farming: A qualitative approach for Germany

et al. 2022

Vegetated strips are in the focus of many stakeholders of agroecosystems and are part of several agri-environmental schemes in Germany. Stakeholders have different expectations and demands on the functionality and services of vegetated strips. In our review, we focused on biodiversity and the ecosystem services pollination, conservation biocontrol, landscape aesthetics, buffer function, and biomass production and their associated functions. We assessed factors that are crucial to support service provision and reviewed trade-offs between the ecosystem (dis)services. We identified five characteristics that are important for the provision of the assessed ecosystem services: age of vegetated strips, flower cover, size or width of the strip, management, and type of adjacent habitat. We conclude that adjusting the target of subsidies with respect to the analyzed factors for biodiversity can help to promote the multifunctionality of vegetated strips in arable farming.
