Transcript

  • 1. Innovations and Challenges in Cynipid Gall Curation Crystal McEwen University of Maryland, College Park, Maryland and Matthew Buffington Systematic Entomology Lab, USDA c/o Smithsonian NMNH
  • 2. Cynipidae • Parasitic Hymenoptera • High host specificity • Gall morphology is often species specific
  • 3. Cynipid Galls 1 Photos by Joyce Gross, calphotos.berkeley.edu 2 Photo by Milan Zubrik, forestryimages.org 3 Photo by Peter Bryant, bathistoc.bio.edu 4 Photo by Graham Calow, naturespot.org.uk 5 Photo by Whitney Cranshaw, Colorado State Univ. 6 Photo by Gerald Lenhard, forestryimages.org 1 1 1 2 1 1 1 3 4 5 6
  • 4. Why Curate Galls? • Extended phenotype – Morphological diversity is often greater in galls than the wasps Top photo from Cals.ncsu.edu
  • 5. Why Curate Galls? • Diagnosis
  • 6. USNM Collection • Last cynipid-specific curator died in 1964 • Roughly 114 drawers • Traditional methods – The Good, the Bad, and the Ugly – Limitations and problems • New methods • New problems and questions
  • 7. The Good Traditional Practices Top (both) and bottom right photos from CP Gillette Museum, CSU
  • 8. The Bad Traditional Practices
  • 9. The Ugly Traditional Practices
  • 10. Problems • Damage to insect specimens and galls
  • 11. Problems • Lost type galls
  • 12. Problems • Visibility
  • 13. New Methods – Clear Boxes
  • 14. New Methods – Clear Boxes
  • 15. New Methods – Clear Envelopes * Not that new but trying to increase usage
  • 16. New Methods – Candy Trays
  • 17. Can cause space issues
  • 18. Electronic Curation - Gigapan
  • 19. New Problems and Questions • What is the status of galls? Type galls? – How do polythalamus galls affect this? – What do we consider galls that don’t have a corresponding wasp? • What are our options for barcoding? • What do we do with huge galls?
  • 20. Extra Notes and Treasures • Hand writing • Vials of nectar • “Pieces of history”
  • 21. Thank you Acknowledgments: Systematic Entomology Lab (USDA- ARS) for funding this project. Thanks are given to Ray Gagne (SEL Emeritus) and Boris Kondratieff (CP Gillette Museum, Colorado State University) for their assistance, and Smithsonian Combined Entomology for additional support.
