Résumé :	Dippers from the genus Cinclus are highly specialised predators on aquatic invertebrates, and occupy linear territories along rivers where measurements of variations in quality are relatively straightforward. For these reasons, they are ideal model species in which to examine factors affecting territory size. In this paper, we investigated the influence of stream habitats on the territory length of the Brown Dipper (Cinclus pallasii) in Taiwan. The biomass of aquatic insects and other stream habitat variables were analyzed to determine their relationships with the territory length of Brown Dippers from November 1988 to May 1989. Compared with slow-moving waters, riffle areas contained significantly greater insect biomass (paired t test, t (11) = 3.49, P
