Drosophila melanogaster images thorax and abdomen from experimentally evolved (with predator) lineages

These images were from an experiment performed by Cody Porter using experimentally evolved lineages of Drosophila melanogaster. In particular these lineages (Experimental evolution performed by Dr. Michael DeNieu while a graduate student) were evolved either with a predator (juvenile Chinese mantids, Tenodera aridifolia sinensis) or no predator control lineages.

Dr. DeNieu speculated based on preliminary observations that the selected lineages may have evolved darker pigmentation. Cody Porter (while an undergraduate researcher in the lab) took standardized images of the Drosophila from the evolved lineages (control and predator) to measure any changes in pigmentation.

While our initial analysis did not show anything, images are provided in case they are useful for other researchers.

This work was conducted in the lab of Ian Dworkin while at Michigan State University.

All images were taken on a LeicaM125 Microscope with a Leica DFC400 digital camera, using Leica Application Suite (LAS) v3.4.0.

Image resolution of 1892 x 1040 px

scale was either 32X or 25X total magnification.

File Naming convention:

treatment (control = con , selection = sel). selection lineages were the ones evolved with

predators. Controls evolved without predators.
1/2 - replicate evolved lineage (2 independently evolved lineages for control and treatment)
four - seven age of the fly being imaged in days
abdomen or thorax - which structure was being imaged
final number is individual




Female selection lineage 1 imaged at seven days old for the abdomen, individual 4.
