Abstract

The brown treesnake (Boiga irregularis, or BTS), a costly invasive species, has been the subject of intensive research on Guam over the past two decades. The behavior and habitat use of hatchling and juvenile snakes, however, remain largely unknown. We used a long-term dataset of BTS captures (N = 2,415) and a dataset resulting from intensive sampling within and immediately around a 5-ha fenced population (N = 2,541) to examine habitat use of BTS…
