These data represent the interaction between two male individuals of California Kingsnakes in Apache Junction, northern Pinal County, Arizona. The interaction was observed, recorded on video, and documented. The dataset is a time series description of the interaction and behaviors of two male California Kingsnakes (Lampropeltis californiae; the two individuals are labeled "B" and "D" for purposes of description) which was used to describe aspects of the interaction in the accompanying publication. Second-by second breakdown of the video sequence provided the "time-stamped" descriptions contained in the data table. These data support the journal article "Lampropeltis californiae (California Kingsnake) behavior, male...
Increases in population density often are associated with a change in mating system structure in numerous taxa. Typically, male interactions are minimal in extremely low density populations. As density increases, males exhibit territoriality but if density becomes too high, the energetic cost of defending a territory will eventually outweigh the reproductive benefits associated with territoriality. Consequently, males in high density populations may abandon territoriality and adopt dominance polygyny, lekking behavior, or scramble competition. We investigated the relationship between population density and mating system structure in three populations of the chuckwalla, Sauromalus obesus (= ater), near Phoenix, Arizona....
