Introduction
Antsareanextremelydiverseandecologicallyimportantgroupofinsects.Theyoccupyacentralroleinmanyecosystems,affectingsoilstructure,nutrientcycling,andseeddispersal.TheSichuanWanglangNatureReserveisoneofthefewremainingareasofprimaryforestinChinaandsupportsarichdiversityofinsects.However,littleisknownabouttheantcommunitiesinthisregion,theirecologicalroles,andtheirrelationshipstootherorganismsinthearea.Therefore,thepurposeofthispaperistoprovideananalysisoftheantdiversityintheSichuanWanglangNatureReserveandthesurroundingarea.
Methods
