资源简介：
An annotated list of spider species is compiled from museum collections and
several personal collections. This list includes 483 species in 20 families;
139 species are new provincial records. The spider fauna of Manitoba is
compared with that of British Columbia, Quebec, and Newfoundland. Manitoba's
spider fauna is composed of northern elements (arctic or subarctic species),
boreal elements (holarctic or nearctic), and eastern elements (mainly species
of the eastern deciduous forest), and a few that are regarded as introductions
from abroad. Forty-three species reach the limits of their ranges here. This
relatively small province (6.5% of the total land mass of Canada) contains 59%
of the Canadian spider families and 37% of the Canadian species.
