The beetle.expl data set is a data frame that contains the relative basal area of the 25 trees closest to the center of each sampled site. The relative basal area is presented by tree species.

Pt

Aspen (Populus tremuloides)

Bp

White birch (Betula papyrifera)

Ab

Balsam fir (Abie balsamea)

Ll

Tamarack (Larix laricina)

Pb

Balsam poplar (Populus balsamifera)

Pc

Lodgepole pine (Pinus contorta)

Pm

Black spruce (Picea mariana)

Pg

White spruce (Picea glauca)

Details

The beetle data has been previously transformed so that the ecological illustration presented in Blanchet et al. (in press) can be easily reproduced. The abundance of carabids was divided by the number of days each trap (there were three traps per sites) was active in the field.
