The Common

The discovery of the common wolf snake, Lycodon aulicus capucinus, on Christmas I . in the Indian Ocean suggests that individuals of the species have colonised the island recently. On the basis of biological information for this widespread colubrid snake and for the brown tree snake, Boiga irregularis, a well-documented pest species on Guam, the establishment of the common wolf snake would pose a severe threat to the native fauna and ecology of Christmas I. Immediate research is needed to document the spread of the snake, to evaluate its effects on other fauna, and to control or eradicate the species before it becomes firmly established.

Accidental Introduction

The accidental introduction of the Brown Tree Snake Boiga irregularis to Guam has resulted in the extirpation of most of the island's native terrestrial vertebrates, has presented a health hazard to infants and children, and also has produced an economic problem. Prevention of its dispersal through Guam's cargo traffic to other Pacific islands has become a high environmental priority. Trapping around ports and other cargo staging areas is central to an integrated pest management programme designed to deter dispersal of the species. In this study, perimeter trapping of forested plots characteristic of those found in port areas was found to be the most effective trap placement strategy, although trap lines cut through the plot interior or placed along a single plot boundary were also effective. Snake removal potentially can be modelled using an exponential decay over time, providing the manager with a planning tool. Population recovery of Brown Tree Snakes in trapped plots was found to be slow in the fragmented forested habitats found around ports.

Abstract The genus Boiga includes 35, primarily arboreal snake species distributed from the Middle East to Australia and many islands in the western Pacific, with particularly high species diversity in South-East Asia. Despite including the iconic mangrove snakes (Boiga dendrophila complex) and the brown tree snake (Boiga irregularis; infamous for avian extinctions on small islands of the Pacific), species-level phylogenetic relationships and the biogeographic history of this ecologically and morphologically distinct clade are poorly understood. In this study, we sequenced mitochondrial and nuclear DNA for 24 Boiga species and used these data to estimate a robust phylogenetic inference, in order to (1) test the hypothesis that Boiga is monophyletic, (2) evaluate the validity of current species-level taxonomy and (3) examine whether geographic range evolution in Boiga is consistent with expectations concerning dispersal and colonization of vertebrates between continents and islands. Our results support the prevailing view that most dispersal events are downstream – from continents to oceanic islands – but we also identify a role for upstream dispersal from oceanic islands to continents. Additionally, the novel phylogeny of Boiga presented here is informative for updating species-level taxonomy within the genus.

Accidental Introduction

The accidental introduction of the Brown Tree Snake Boiga irregularis to Guam has resulted in the extirpation of most of the island's native terrestrial vertebrates, has created a health hazard to infants and children, and has resulted in economic losses. Cargo inspections using teams of handlers and their detector dogs form a last line of defense for preventing Brown Tree Snake dispersal from Guam. To assess the efficacy of the teams of handlers and their dogs for locating stowed Brown Tree Snakes, we planted Brown Tree Snakes (in escape-proof containers) in cargo without the knowledge of the handlers inspecting the cargo. We found that when an observer attended the inspection to monitor procedures, 80% of the planted snakes were located. Without an attending observer present, 70% of the planted snakes were discovered, but only after such plantings had become a routine procedure. Prior to the routine planting of snakes, efficacy was nearly 50% less (38%). The reasons some planted snakes were missed by the dog teams were split between: an insufficient search pattern by the handler, or the dog giving no discernable indication that a snake was present.
