Habitat affinities of 228 boreal Finnish spiders: A literature review

Abstract

Information about the habitat affinities of spiders is necessary in ecological studies. I focused on two factors in habitats of spiders: light intensity and moisture. First, the habitats were classified according to these factors. Canopy cover and tree species composition were used to indicate the amount of sunlight reaching the ground. Habitat moisture was determined indirectly from the vegetation. Second, the spider species were classified according to what kind of a habitat they were found in the literature. This paper updates and continues Huhta's (1971) classification, including 228 boreal spider species, based on Finnish literature from boreal region.
