The journal aims to build up quality information on the “animal diversity” of Southeast Asia in particular. The journal will also publish papers from outside the stated geographic range that deal with material deposited in the Zoological Reference Collection (ZRC) of the Lee Kong Chian Natural History Museum (LKCNHM), National University of Singapore. Both descriptive and experimental papers will be considered. Similarly, both single species (except for insect taxa) and ecosystem studies will be considered for publication. Single species descriptions for insect taxa are not accepted except under strong recommendations from Editors. Manuscripts that are checklists or based on new records will no longer be accepted unless they are of significant scientific value.
