Translocation experiments with butterflies reveal limits to enhancement of poleward populations under climate change

Grants/Fellowships in support:

Program for Ecosystem Research, US Department of Energy (for biogeographic studies & genomic research) (2007, 2006, 2005)

 

Project Overview:

Performed a reciprocal translocation experiment of Propertius duskywing skipper (Erynnis propertius) and Anise swallowtail (Papilio zelicaon) both in the field and a simulated translocation experiment in growth chambers to determine if populations differ in their response to warming and if that response is mediated by host plant.

 

Activities Conducted:

  • Field capture of wild Erynnis propertius and Papilio zelicaon females
  • Portable Greenhouse oviposition on field collected native host (Oak for Erynnis and Parsley for Papilio)
  • Reciprocal translocation of eggs to field sites (field trials) or growth chambers (simulated trials).
  • Tending of eggs/larvae on field/greenhouse propagated native host (Quercus garryana [Erynnis], Petroselinum crispum [Papilio] )
  • Assessment of larvae, pupae, and adults for survivorship, mass and morphology (head capsule width).
  • Additional genetic/genomic studies including microsatellite analyses for geneflow assessment and 454 sequencing and microarray design for transcriptome-level response assessment.
