Geographical variation in agonistic behaviour in a ring species of salamander, Ensatina eschscholtzii
Article Abstract:
Four populations of a ring species of salamander, Ensatina eschscholtzii, were the subjects of the examination of overt aggressive, passive aggressive/exploratory, sensory and avoidance behavior divergence. Resident individuals were paired with intruders belonging to another population. Results reveal that the behavior of residents is affected independently by the population of both residents and intruders but not by the interaction between the two populations. Behavioral divergence consistent with the phylogenetic history of the species was also observed.

Agonistic and sensory behaviour of the salamander Ensatina eschscholtzii during asymmetrical contests
Article Abstract:
The territorial behavior of the western plethodontid salamander Ensatina eschscholtzii was analyzed to determine the interaction between residency and body size. Results showed that resident salamanders had stronger agonistic and sensory behavior than intruders and that body size was negated. Female salamanders performed more aggressive behavior than females, suggesting that males rely less on olfactory senses in assessing territories and potential mates.

An experimental analysis of joint nesting in the salamander Hemidactylium scutatum (Caudata: Plethodontidae): the effects of population density
Article Abstract:
An analysis of the joint nesting behavior of the plethodontid salamander, Hemidactylium scutatum, shows that the population density of females is not directly related to the proportion of joint nests. Joint nesting occurs under both high-density and low-density conditions. The joint nesting tendency is also not associated with the aggressive usurption of nests or brood parasitism.
