  • Plethodontid salamanders usually exhibit territorial spacing patterns and behaviors. Previous works suggest that plethodontids from Vancouver Island, Canada lack strong territoriality. In one Vancouver Island species, Aneides vagrans, salamanders may even be found in the field in small aggregations. We investigated preferences of A. vagrans for occupied vs unoccupied cover objects and for cover objects occupied by conspecifics of different age/size classes. We also tested A. vagrans preferences for conspecific vs heterospecific salamanders in an attempt to determine if the lack of territoriality by A. vagrans is species-specific and perhaps related to habitat segregation. A. vagrans did not avoid occupied cover objects or exhibit a preference for occupied vs unoccupied sites. Age class did not affect cover object choice. A. vagrans did not avoid heterospecifics that exhibit the highest degree of resource overlap (Plethodon vehiculum), which we believe might be attributable to a benign and resource-rich habitat, although alternative explanations exist. A. vagrans did avoid syntopic newts (Taricha granulosa), though this is probably due to toxic newt skin secretions. [PUBLICATION ABSTRACT]
