The effects of three-dimensional gap orientation on bridging performance and behavior of brown tree snakes (Boiga irregularis).

Scaling of the axial morphology and gap-bridging ability of the brown tree snake, Boiga irregularis.

Networks of branches in arboreal environments create many functional challenges for animals, including traversing gaps between perches. Many snakes are arboreal and their elongate bodies are theoretically well suited for bridging gaps. However, only two studies have previously investigated gap bridging in snakes, and the effects of size are poorly understood. Thus, we videotaped and quantified ...

Incline and peg spacing have interactive effects on the arboreal locomotor performance and kinematics of brown tree snakes, Boiga irregularis.

Many animals move using lateral undulations, but snakes are noteworthy for using this type of locomotion in an unusual diversity of environments, including trees in which both the spacing and orientation of branches vary considerably. Despite branches providing discrete locations for snakes to generate propulsive forces during lateral undulation, the consequences of branch spacing for the locom...

Ontogenetic Shifts in Canion Attractiveness to Brown Tree Snakes (Boiga irregularis)

Physiological evidence for reproductive suppression in the introduced population of brown tree snakes (Boiga irregularis) on Guam

Introduced species are an increasingly pervasive problem. While studies on the ecology and behavior of these pests are numerous, there is relatively little known of their physiology, specifically their reproductive and stress physiology. One of the best documented introduced pest species is the brown tree snake, Boiga irregularis, which was introduced onto the Pacific island of Guam sometime ar...

Experiments on Chemical Control of Behavior in Brown Tree Snakes

The brown tree snake (Boiga irregularis), accidentally introduced on Guam shortly after World War 11, is the target of extensive efforts aimed at reducing populations and preventing their spread to other Pacific islands. Chemical attractants and repellents have been investigated, and this paper presents an overview of current knowledge. In particular, chemical cues that have strong effects in l...
