Adian+Linds_1215seg_54spp_Metadata.csv

Seg: Entire transect or transect segment used as a sampling unit. Code consists of transect number and distance of the segment midpoint from the beginning of the transect.

Country

Set: NW, SW and central Amazonia, defined on the basis of proximity to the Andes and rainfall seasonality

Quality: abu = standard 0.25-ha transect (5 m by 500 m) with number of individuals counted for each species. pa = 500-m-long transects that are either 2 m or 5 m wide, presence and absence of species registered. pres = transects of either 250 m or 500 m long and either 2 or 5 m wide, presence-only data as individuals whose species identification has not been confirmed were removed from the data.

SegArea: surface area of the segment in square metres

logCat = log10-transformed values of the surface soil concentration of Ca+Mg+K as measured in cmol(+)/kg

Data_provider: the person who collected the field data

Adian_spp, Linds_spp, Total_spp: number of species in these genera observed in each transect segment, including morphospecies for which matching species name has not been found

Adian_HOF, Linds_HOF, Total_HOF: number of fully identified species in these genera, which are used in that HOF and WA analyses
