說明
Within the framework of a two-year project ground beetles were assessed in corn fields,grown for biogas production, with or without a two seed mixtures flower strip as well as in the adjacent forest. Study sites were situated within conventional fields typical for the agricultural landscapes in northern German lowlands in direct proximity to the nature reserve Lüneburger Heide.
We provide data on 34 413 specimens belonging to 93 ground beetle species. Four species have been classified as being Near Threatened within Germany. At the level of the Federal State Lower Saxony, four species are classified as Endangered, nine species as Vulnerable and one as Near Threatened, highlighting the importance of this data set also for conservation purposes.

地理涵蓋範圍
The study was carried out in North German lowlands in the north-east of the Federal State of Lower Saxony. The majority of the study sites (14) were located in the municipality of Undeloh in the district of Harburg and the remaining eight were located in the adjacent municipality of Bispingen in the district of Heidekreis.

| 研究區域描述 | The study area is located in north-west Germany (Lower Saxony). The region represents a hilly landscape consisting of deposits of the penultimate glacial period (Saale glacial period) and is currently dominated by agricultural and forest areas with patches of heathlands. The latter are preserved as historical cultural landscapes for nature conservation purposes. The climate is temperate suboceanic. Within this region, we selected 22 study sites. 14 of them are located in the district of Harburg, and 8 in the district of Heidekreis. |
| 研究設計描述 | The experiment followed a repeated partly split-plot design. We selected 22 fields where corn (Zea mays) was grown for the two years of the study which at least one edge adjacent to a forested area. On half of the fields (11) a flower strip 30m wide and 200m long was sown alongside the forest edge. Flower strips were divided into two equal parts, 100m long, and sown with two different seed mixtures. The first one is a standard seed mixture only containing seven non-native annual cultural flowering species commonly used for green manure. The second mixture was enriched with annual native herb species thus totalling 21 plant species. Both flower strips were annual and sown each year in April. Pitfall traps were installed at 15m distance from the forest edge and from each other. Five traps were set in the forest as well as in the corn field treatment. In the flower strips, three traps per seed mixture were installed. Traps were run continuously (except when the farmers worked the field), but for this dataset only traps that were open between June to August were analysed, since the vegetation of the flower strips is well established within these months, and effects of flower strips were expected to be most pronounced. If available, three traps per habitat, treatment and seed mixture (forest / corn field / flower strip standard / flower strip enriched) and time interval were evaluated. |

取樣方法
Pitfall traps filled with so-called Renner-solution were installed in early spring (April 2017) except for the sites H13 and H14 which were installed one year later in April 2018. Traps were covered with wire mesh to prevent vertebrates from falling in. The sides of the wire were bent up so that even large specimens running on the ground could still fall in. Traps that went into the analysis were those that were within the months June to August of both years. The traps remained opened for 14 to 44 days, depending on weather conditions. Traps were changed more often when temperatures were high or after heavy rainfalls (to avoid dilution of the trapping solution).

| 品質控管 | All collected individuals were identified by Swantje Grabener, Christin Juno Laschke, Sina Remmers and Lena Husemann in the laboratory and at least ten individuals per species (if available) were identified by the professional taxonomists Thorsten Assmann, Stephan Gürlich and Estève Boutaud. |
方法步驟描述:
- Traps were labelled in the field and further stored at 7°C until samples were processed, and carabid beetles were identified in the laboratory. Data on species identity, number of individuals per species, the person who identified the species as well as the year of identification and, if necessary, the person who verified identification and the year of verification, were put into a table format together with the trap information. Specimens from the same trap were stored in vials containing Scheerpeltz-solution (70% ethanol, 5% acetic acid) for long-term storage. For each species, at least ten specimens (if available) were mounted and labelled with all trap and identification information. The locations were retrieved using a standard GPS system. Coordinate uncertainty was set to 100m as for the coordinates the centre of the study site was entered so that all traps from one study site had the same geographic coordinates despite the traps thus ignoring the actual position of the traps.
