Dictyostelid Cellular Slime Molds from Christmas Island, Indian Ocean

ABSTRACT Christmas Island (10°30′S, 105°40′E) is an Australian external territory located in the Indian Ocean, approximately 350 km south of Java and Sumatra and about 1,550 km northwest of the closest point on the Australian mainland. In May 2017, 20 samples of soil/humus were collected on Christma...
