Laucht et al. (2019) Vole field effect studies for ERA refinement at higher tiers How many voles are enough
The current EFSA bird and mammal guidance 2009 gives advice on how potential adverse effects of pesticides on wild vertebrates can be assessed One option for higher tier assessments is to conduct field effect studies to monitor potential acute or long term effects on small mammal populations using a capture mark recapture design However,

Esther et al. (2019) Proposed Indoor Test Procedure to Quantify Pesticide Treatment Effects on Seed Consumption by Birds
Pesticides used in seed coatings can influence seed consumption by birds and, therefore, actual exposure risk for them. A quantification of such effects on consumption is currently not regarded as a refinement factor in environmental risk assessments, although it is a possible option and should be considered, for example, for comparing exposure risk of different pesticides.

Lückmann, Faupel, Ludwigs (2018) ‘Focal species’ – can this well-known concept in higher-tier risk assessments be an appropriate approach for solitary bees?
Bumble bees and solitary bees have to be considered in addition to honey bees regarding environmental pollinator risk assessments. For solitary bees it is proposed to use Osmia cornuta (LATR., 1805) or O. bicornis (L., 1758) as test organisms.

Montinaro, Grimm, Ludwigs (2018) Telemetry study on the common toad (Bufo bufo) during postbreeding migration through cereal fields in Germany
The recent Scientific Opinion on the state of the science on pesticide risk assessment for amphibians and reptiles (EFSA 2018) points out the need to collect more data on the ecology of amphibians to reduce uncertainties when assessing the potential risks associated with exposure to pesticides.

Montinaro et al. (2018) Telemetry of sand lizards (Lacerta agilis) in vineyards – Are methods established for terrestrial vertebrate risk assessments effective in recording higher tier data for reptiles?
Habitats bordering vineyards represent primary habitats for reptiles. This taxon can become exposed when foraging between vineyards, where pesticide application is frequent. EFSA (2018) suggests the sand lizard as a focal species to represent other lacertids living in agricultural land.

Sgolastra et al. (2018) Pesticide Exposure Assessment Paradigm for Solitary Bees
Current pesticide risk assessment for bees relies on a single (social) species, the western honey bee, Apis mellifera L. (Hymenoptera: Apidae). However, most of the >20,000 bee species worldwide are solitary.

Vallon et al. (2018) Focal Species Candidates for Pesticide Risk Assessment in European Rice Fields: A Review
An assessment of potential risks of pesticides on wildlife is required during the process of product registration within Europe because of the importance of agricultural landscapes as wildlife habitats. Despite their peculiarity and their specific role as artificial wetlands, rice paddies are to date pooled with cereals in guidance documents on how to conduct risk assessments for birds and mammals in Europe.

Gradish et al. (2018) Comparison of Pesticide Exposure in Honey Bees (Hymenoptera: Apidae) and Bumble Bees (Hymenoptera: Apidae): Implications for Risk Assessments
To date, regulatory pesticide risk assessments have relied on the honey bee (Apis mellifera L.) (Hymenoptera: Apidae) as a surrogate test species for estimating the risk of pesticide exposure to all bee species. However, honey bees and non-Apis bees may differ in their susceptibility and exposure to pesticides.

Alscher, Hecht-Rost, Lückmann (2017) On the way to a new guideline: Results of three years of bumble bee semi-field testing
According to the EFSA Guidance Document on bees (EFSA, 2013), not only honey bees but also bumble bees should be considered in the risk assessment of plant protection products. Up to now, no official guideline for standardised semi-field trials is available to assess effects on bumble bees.

Laucht et al. (2017) Habitat preferences of linnets (Linaria cannabina) in vineyards
A large part of vineyards in Europe show no or very little ground vegetation, due to chemical and non-chemical weed control. But management techniques have started to change in the last years resulting in a reduction in herbicide applications and in an increase in ground vegetation growth and cover.

Lückmann et al. (2017) Fenoxycarb, a suitable reference item in semi-field testing on the solitary bee Osmia bicornis (L., 1758) (Hymenoptera, Megachilidae)?
According to the ‘EFSA Guidance Document on the risk assessment of plant protection on bees’, not only honeybees but also bumble bees and solitary bees have to be considered for the first time. But for testing of solitary bees under laboratory, semi-field and field conditions no official test guideline exists.

Ludwigs et al. (2017) Skylarks nesting in pesticide-treated fields compared to those nesting in non-treated agricultural land and main reasons for complete nest loss
Pesticides are commonly considered a cause of species decline in farmland. In the past, most studies have focused on acute effects of pesticides on adult birds or on indirect effects on offspring (e.g. mortality due to limited food resources as a result of pesticide use).
