Geography comments: "Fukui Prefecture... along Echizen coast"
Climate and habitat
Habitat: temperate broadleaf/mixed forest
Substrate: ground surface
Disturbance: selective logging
MAT: 15.4
MAP: 1537.0
Habitat comments: "There are scattered coniferous plantations in the vicinity, and in the netting site deciduous broadleaved trees are dominant and these trees are cut down evenly up to 4 or 5m height"
climate data are for Fukui and are from Takahashi et al. (2018, Mycoscience)
Life forms: birds
Sampling methods: line transect, mist nets, baited
Sample size: 3537
Years: 1975
Days: 38
Seasons: autumn
Nets or traps: 52
Sampling comments: "Some fifty mist-nets lined up were set an interval of 4-7m in the area. Song and call notes of several species from 1 or 4 tape-recorders were utilized instead of a live decoy birds"
sampling was during October and/or November each year
a mix of 6 and 12 m nets and of 24 and 36 mesh nets was apparently used, and the number of 12 m net equivalents varied considerably from year to year and within seasons
it went from 18 to 35.5 in 1973 and from 9 to 36 to 46.5 to 56.5 in 1974, and it was fixed at 52, 48, and 48 nets during 1975, 1976, and 1977
I use midpoint values of 26.75 and 37 for 1973 and 1974 because that's close enough
