Predation on pomacea & radix snails during non-rice growing periods by the Philippine ricefield rat, Rattus tanezumi Temminck
Predation preference by the principal rodent pest species, the Philippine ricefield rat, Rattus tanezumi Temminck (formerly known as Rattus rattus mindanensis), for the invasive alien freshwater snail, the golden apple snail, Pomacea canaliculata; native non-pest freshwater snail, Radix quadrasi; an...
