“The sites were three Scots pine Pinus sylvestris L. forests of different age (Young, Middle and Old) in the Northern Vidzeme Biosphere Reserve (northern Latvia). The Young site was 30–40 years old, the Middle site was 50–70 years old and the Old site was 150–200 years old, forest stand.” “A spatially explicit sampling design was used at the three sites. Once a year, for nine consecutive years (1998–2006), a sampling grid (cf. Dirilgen et al., 2018) comprising five parallel 40-m long transects (10 m apart) was laid out at each site and 20 evenly spaced samples (2.5 cm diameter by 10 cm depth) taken along each transect to give a total of 100 samples per date per site. Given the destructive nature of the sampling, transects were moved to the right by 0.5 m each year to avoid resampling the same spot while sampling the same local population. Oribatids were extracted using a modified Macfadyen high gradient extractor, counted with densities expressed as ind./m2 and identified to species level using Bulanova-Zachvatkina (1967), Weigmann (2006) and specific works cited therein.” [Extracted from Caruso et al 2020]
