“…Previous studies have usually used suction samples, sweep net samples [17], light sources [19,20], and pitfall traps [18,21] to collect diel dynamics data of ground-dwelling invertebrate communities. However, these methods are timeconsuming, labor-intensive, and costly [22], usually requiring relatively coarse temporal intervals, such as 3 [23], 4 [24], 6 [17], or 12 h [25] intervals. Therefore, it is still unclear whether significant variation exists within a 24 h period in ground-dwelling invertebrate communities at 1 h intervals.…”

We evaluated the hourly dynamics of ground-dwelling invertebrate communities in farmland using infrared camera traps between August and September 2022. No significant variations within 24 h nor between any two time points of each day were observed in the taxonomic richness and abundance of the entire community. However, the periods from 4:00 to 7:00 and 13:00 to 20:00 showed relatively high taxonomic richness, while those from 2:00 to 6:00 and 16:00 to 21:00 showed relatively high abundance. Millipede abundance varied significantly in a 24 h period, with higher abundance from 3:00 to 4:00 and 1:00 to 2:00. Additionally, slug, beetle, and grasshopper abundances were significantly higher from 22:00 to 23:00, 17:00 to 18:00, and 23:00 to 24:00, respectively. The abundance of other taxa did not show significant variations between any two time points of a day. Predominant generalist predators showed positive correlation in their activity times. These results suggest that significant variations within each 24 h period are uncommon at either community or taxa (except for millipedes) levels in farmland ground-dwelling invertebrates. Further, while most taxa had significantly preferred active hours, the total community did not. Therefore, hourly dynamics should be considered to understand biodiversity maintenance.

The aim of this study was to evaluate skidding techniques, which result in minimal damage to the soil, depending on the slope and stand type. Thus, three skidding techniques with tractor for harvesting (suspended skidding [SS], using a skidding cone [SC], and cable-pulling [CP]) were used in six different study sites and the variations in soil properties were examined at three different slopes (0%–20%, 20%–33%, >33%), 2 different stand types (A, B), and 2 different soil depths (0–5 cm, 5–10 cm). Soil bulk density, soil organic matter, soil compaction, organic carbon (C), and total nitrogen (N) were determined. The Entropy and TOPSIS methods were used among the multiple-criteria decision-making methods for six different coniferous stands. With the combination of the Entropy and TOPSIS methods, we found that slope was an important factor in determining the preferred skidding technique. Suspended skidding was seen as the preferred method of skidding technique in the 0–20% slope group. For the 20%–33% slope group, the usability of the three methods varied depending on stand type and soil depth, whereas the technique using a skidding cone was found to be the preferred skidding technique in the > 33% slope group. Study Implications Sustainable forest management can be ensured by managing forests in consideration of ecological, economic, and social dimensions. For these reasons, forests can be used efficiently for the long term with the identification of the most appropriate operation and harvesting techniques. Logging operations, used for harvesting by the forestry sector, is the management of a biological asset that is open to natural conditions and dependent on the soil and causes several impacts on forest soil structure. The damage leads to negative consequences for sustainability and productivity of the forest ecosystem. This study demonstrated that it is possible to reduce soil damage by using the most preferred or ideal site-specific skidding technique.
