Carabids are abundant in agroecosystems and provide biocontrol services by feeding on weed seeds and pests. We compare the effects of two fundamentally different agri-environmental schemes (AES) on the numeric and trophic responses of four common carabid species: Anchomenus dorsalis, Poecilus cupreus, Pseudoophonus rufipes and Pterostichus melanarius. 2. In six cereal fields under organic farming and six sown flowering fields, 10 290 individuals of the four species were sampled to quantify their numeric response. The activity density of all species was higher in organically managed cereal fields compared to flowering fields. 3. We analysed naturally occurring stable isotope ratios of carbon and nitrogen in 138 carabid individuals to quantify isotopic niches and the diet contribution of soil- versus plant-based resources. Resources from the soil ('brown') energy channel were more important than resources from the plant ('green') energy channel in the diet of all species, particularly in P. melanarius. 4. Isotopic niches were larger for P. rufipes and P. melanarius in flowering fields than in organically managed cereal fields. Moreover, differences between AES types were observed in the diet contribution derived from both energy channels: A. dorsalis and P. cupreus incorporated higher proportions of plant-based resources in organically managed cereal fields compared to flowering fields. 5. Similar numeric, but different trophic responses suggest that AES type may alter arthropod food webs beyond simple changes in carabid densities. Such 'hidden' modifications in the resource utilisation of generalist predators deserve more attention to adequately evaluate the ecological consequences of AES.}, language = {en} } @misc{MaderDiehlFiedleretal., author = {Mader, Viktoria and Diehl, Eva and Fiedler, Daniela and Thorn, Simon and Wolters, Volkmar and Birkhofer, Klaus}, title = {Trade-offs in arthropod conservation between productive and non-productive agri-environmental schemes along a landscape complexity gradient}, series = {Insect Conservation and Diversity}, volume = {10}, journal = {Insect Conservation and Diversity}, number = {3}, issn = {1752-4598}, doi = {10.1111/icad.12220}, pages = {236 -- 247}, language = {en} } @misc{HerrDeBockDiehletal., author = {Herr, Raphael and De Bock, Freia and Diehl, Katharina and Wiedemann, Eva and Sterdt, Elena and Blume, Miriam and Hoffmann, Stephanie and Herke, Max and Reuter, Marvin and Iashchenko, Iryna and Schneider, Sven}, title = {Associations of individual factors and early childhood education and care (ECEC) centres characteristics with preschoolers' BMI in Germany}, series = {BMC Public Health}, volume = {22}, journal = {BMC Public Health}, issn = {1471-2458}, doi = {10.1186/s12889-022-13814-5}, pages = {1 -- 13}, abstract = {Background The number of obese children is rising worldwide. Many studies have investigated single determinants of children's body mass index (BMI), yet studies measuring determinants at different potential levels of influence are sparse. The aim of this study is to investigate the independent role of parental socioeconomic position (SEP), additional family factors at the micro level, as well as early childhood education and care (ECEC) centre characteristics at the meso level regarding BMI. Methods Analyses used the baseline data of the PReschool INtervention Study (PRINS) including up to 1,151 children from 53 ECEC centres. Multi-level models first estimated the associations of parental SEP indicators (parental school education, vocational training, and household income) with the children's standard deviation scores for BMI (SDS BMI, standardised for age and gender). Second, structural (number of siblings), psychosocial (strained family relationships), and nutrition behavioural (soft-drink consumption, frequency of fast-food restaurant visits) family factors at the micro level were included. Third, characteristics of the ECEC centre at the meso level in terms of average group size, the ratio of overweight children in the group, ECEC centre type (all-day care), and the location of the ECEC centre (rural vs urban) were included. All analyses were stratified by gender and adjusted for age, migration background, and parental employment status. Results Estimates for boys and girls appeared to differ. In the full model, for boys the parental SEP indicators were not related to SDS BMI. Factors related to SDS BMI in boys were: two or more siblings; B = -.55; p = 0.045 [ref.: no sibling]), the characteristics of the ECEC centre in terms of average group size (20 - 25 children; B = -.54; p = 0.022 [ref.: < 20 children]), and the ratio of overweight children (more overweight children B = -1.39; p < 0.001 [ref.: few overweight children]). For girls the number of siblings (two and more siblings; B = .67; p = 0.027 [ref.: no sibling]) and average group size (> 25 children; B = -.52; p = 0.037 [ref.: < 20 children]) were related to SDS BMI. Conclusions The BMI of preschool children appears to be associated with determinants at the micro and meso level, however with some gender differences. The identified factors at the micro and meso level appear largely modifiable and can inform about possible interventions to reduce obesity in preschool children.}, language = {en} } @misc{MayerHerrKleinetal., author = {Mayer, Alena and Herr, Raphael M. and Klein, Thomas and Wiedemann, Eva and Diehl, Katharina and Hoffmann, Stephanie and Blume, Miriam and Jepsen, Dennis and Sundmacher, Leonie and Andreas, Marike and Schneider, Sven}, title = {Socio-economic inequalities in body mass index among preschool children: do sports programs in early childhood education and care centers make a difference?}, series = {Frontiers in Public Health}, volume = {Vol. 11}, journal = {Frontiers in Public Health}, issn = {2296-2565}, doi = {10.3389/fpubh.2023.1079871}, abstract = {Background: Overweight in childhood is considered to be one of the most serious public health challenges. Many studies have investigated individual-level determinants of children's body mass index (BMI), yet studies exploring determinants at the meso-level are sparse. The aim of our study was to examine how a sports focus at early childhood education and care (ECEC) centers moderates the effect of parental socio-economic position (SEP) on children's BMI. Methods: We used data from the German National Educational Panel Study and included 1,891 children (955 boys and 936 girls) from 224 ECEC centers in our analysis. Linear multilevel regressions were used to estimate the main effects of family SEP and the ECEC center sports focus, as well as their interaction, on children's BMI. All analyses were stratified by sex and adjusted for age, migration background, number of siblings, and employment status of parents. Results: Our analysis confirmed the wellknown health inequalities in childhood overweight with a social gradient toward a higher BMI for children from lower SEP families. An interactive effect between family SEP and ECEC center sports focus was found. Boys with low family SEP not attending a sports-focused ECEC center had the highest BMI among all boys. In contrast, boys with low family SEP attending a sports-focused ECEC center had the lowest BMI. For girls, no association regarding ECEC center focus or interactive effects emerged. Girls with a high SEP had the lowest BMI, independent of the ECEC center focus. Conclusion: We provided evidence for the gender-specific relevance of sports-focused ECEC centers for the prevention of overweight. Especially boys from low SEP families benefited from a sports focus, whereas for girls the family's SEP was more relevant. As a consequence, gender differences in determinants for BMI at different levels and their interaction should be considered in further research and preventive measures. Our research indicates that ECEC centers may decrease health inequalities by providing opportunities for physical activity.}, language = {en} }
