  1. 1. Presented by: Masa and OlivarOptimizing Diversity AssessmentProtocols for High Canopy Ants inTropical Rain Forest
  2. 2. Why Ants?• Most abundant and ecologically important group• Population decline affect the rates of ecosystemprocesses such as nutrient redistribution (Fayle etal. 2011)
  3. 3. InquiryWhich among the sampling techniques can givethe highest number of ant individuals, numberof species and species composition?1. Fogging2. Baited Pitfall Trap3. Purse-String Trap
  4. 4. Segama Forest Reserve, Sabah,Malaysia – Lowland DipterocarpForest
  5. 5. 1. Fogging• Igeba TF 35 fogging machinewith synthetic pyrethruminsecticide (active compound:Alphacypermethrin withsynergist 2.27%)• 10 fogging trays• 10 min• Carried out at 6 am• Trays left for 3 hours
  6. 6. 2. Baited Pitfall TrapAttachment to BranchMesh containing bait(Tuna and sweets)Water with Detergent
  7. 7. 3. Purse-String Trap
  8. 8. Results0102030405060708090100Abundance DiversityFoggingBaited PitfallPurse-String39,351 ants 173 species 38 genera
  9. 9. DiscussionSAMPLING TECHNIQUE ADVANTAGES DISADVANTAGESFogging Most efficient Greatly disturbs theecosystemBaited Pitfall Allows catching of speciesactive throughout a 24-hperiodRun for longer periods oftime to catch reasonablenumbers of ants (caughtare clumsy ants)Purse-String Trap Powerful method incollecting ants on verysmall spatial and temporalscalesDoes not allow the wholecanopy of the tree to besampled
  10. 10. Conclusion• Fogging > Purse-string > BaitedPitfall in terms ofspecies abundanceand diversity• Authors suggestthat in choosing asamplingtechnique, onemust first considersampling time.
