https://researchdata.se/en/catalogue Search results en From May until September 2020, micro- and macroclimatic temperature were measured along a 1200 km latitudinal gradient in Sweden. Microclimatic temperature was measured hourly under the bark of spruce logs, while macroclimatic temperature refers to measured air temperature 1.3 m above the ground at the same study sites. From April until September 2021, saproxylic beetles were collected at these study sites. The data set "boreal_forest_climate_data" contains 12 columns and 88 rows. Block: six different study sites are distributed from southern (1) to northern Sweden (6). Plot: five study plots that contains one study site. Block 1: Plot 11-15 Block 2: Plot 6-10 Block 3: 16-20 Block 4: 21-25 Block 5: 1-5 Block 6: 26-30 Shade: three different shade level at one plot. 1: sun-exposed, 2: intermediately shaded and 3: fully-shaded. Mikro- and makrotemp: mean temperatures per Block, plot and shade. CTI: community temperature index per Block, plot, and shade. Bark: Remaining bark at every spruce log. Diameter: Diameter of the spruce logs. Regional climate: Average temperature measured by nearby weather stations for every block over the period from May-September 1990-2020 in °C. Aspect: Aspect in degrees of every plot. Species richness: Species richness per Block, plot, and shade. Totalab: Abundance per Block, plot, and shade. Dataset "specieslist_xylo" contains 6 columns and 3460 rows. Log: 15 Spruce logs distributed over different shade levels on every plot. Spruce logs 1,4,7,10 and 13 on shade level 1; spruce logs 2,5,8,11 and 14 on shade level 2 and spruce logs 3,6,9,12, and 15 on shade level 3. Sampling_date: Date, when beetle species were collected. Species: Name of saproxylic beetle species found in each spruce log. Number: Number of each species found in each spruce log. STI: Species temperature index for every beetle species.

The landscape parameters investigated include the cover of cropland as measure of landscape simplification, the absolute inter-annual change in host crop cover (sugar beet), the landscape-level crop diversity in the previous year and the edge-density in the surrounding landscapes. The pests were monitored in a standardised monitoring scheme with one observation plot in each field and the respective values represent the maximum observed densities or damage at economically relevant development stages (see detailed description below). Pest densities and damage were recorded in five clusters of five plants selected at random within the observation plot avoiding plot edges and tractor tracks. Landscape parameters were extracted from the official land-use maps provided by the Danish Agricultural Agency (Landbrugsstyrelsen, 2024. Internet Markkort (IMK). Ministeriet for Fødevarer, Landbrug og Fiskeri, København) and the Swedish Board of Agriculture (Jordbruksverket, 2024. Kartor och Geografiska informationssystem - Årslager skiftesdata. Jordbruksverket) at three buffer radii (500 m, 1000 m and 2000 m) around the centre of the observation plots. For further information, see methods in the publication Boetzl et al. (2026) Landscape-scale drivers of insect pest regulation in sugar beet. Agriculture, Ecosystems and Environment. The data in the 'sugarbeet_pests_data.csv' file have information on the prevalence and damage caused by five major sugar beet pests (black bean aphid, pygmy mangold beetle, flea beetles, beet leafminers and thrips) at the respective economically relevant sugar beet growth stages recorded in 134 fields ('ID') in Denmark and Sweden as well as landscape parameters in the landscapes surrounding these fields at three spatial scales (500 m, 1000 m and 2000 m). 135 rows. 'NA' indicates missing values. SLU has led data analysis and publication of the scientific article. Nordic Beet Research has coordinated data collection. University of Copenhagen has contributed to data interpretation.
