Abstract

Taiga bog arachnids, mainly collected in pitfall or pan traps, are compared for two Manitoba regions, one southern and one northern. The dominant spider families in the south are Lycosidae, Clubionidae, and Erigonidae, whereas in the north they are Erigonidae, Lycosidae, Linyphiidae, and Gnaphosidae. The southern taiga bog has 82 species, the northern taiga, 39 species, with 16 species common to both regions. Two opilionid species were collected in the south and none in the north.

Résumé

Les arachnides de tourbière boréale, ramassés principalment dans les trappes du fond ou du bassin, dans le sud et dans le nord du Manitoba, sont comparables. Les familles dominantes d’araignées dans le sud sont Lycosidae, Clubionidae et Erigonidae, alors que dans le nord elles sont Erigonidae, Lycosidae, Linyphiidae et Gnaphosidae. Le taiga du sud a 82 espèces, et celui du nord, 39 espèces, dont 16 espèces partagées entre les deux endroits. On retrouve deux espèces d’opilionides dans le sud et aucune dans le nord.
