We used multiple regression, as before, grouping beetle responses by a single factor, family, with 16 categories, one for each family: (1) Anobiidae, (2) Bostrichidne, (3) Carabidae, (4) Corylophidae, (5)
Cryptophagidae, (6) Curculionidae, (7) Elateridne, (8) Lathridiidae, (9) Leiodidae, (10) Oedemeridae, (11) Pselaphidae, (12) Ptiliidae, (13) Scarabaeidae, (14) Scydmaenidae, (15) Staphylinidae, and (16) Tenebrionidae.
