Abstract

ABSTRACTSince 1937, thirteen species of non‐indigenous anurans have made their way to Guam. Of these, at least six have established breeding populations. Various pathways led to the introduction of these species to the island. The only anuran intentionally introduced wasChaunus marinus(formerlyBufo marinus), which was brought to Guam as a biocontrol agent.Kaloula picta, K. pulchra, Polypedates leucomystax, and probablyLitoria fallaxarrived as stowaways via maritime or air‐transport vessels.Eleutherodactylus coquiandEuhyas(formerlyEleutherodactylus)planirostrisappear to have entered Guam through the horticultural trade. Specimens ofPseudacris regillawere found among agricultural products and Christmas trees. Five species have been transported to Guam via the aquacultural trade. The importation of tilapia, milkfish, and white shrimp from China, Hong Kong, Taiwan, and the Philippines was associated with the introduction to Guam ofFejervarya cancrivora, F. limnocharissensu lato,Microhyla pulchra, Polypedates megacephalus, andSylvirana guentheri(formerlyRana guentheri). Presently, no quarantine or containment guidelines have been established for Guam's aquacultural industry.
