Coordinates tracing 2D outlines of beaks (birds and squid)

  • 1. University of Utah

Description

Two-dimensional coordinates for lines traced onto images of beaks.

  • This is a .zip archive xy coordinates (250 files, .txt); and a list of specimen names (1 file, .csv).
  • All images traced in FIJI.
  • For each specimen, there is a trace of the beak rostrum and a separate trace of the beak bite surface.
  • Each trace file should be a list of xy coordinates that ends at the beak tip. This must be checked/verified/corrected for all files before running any analyses! I recommend visual inspection by plotting each beak dataset as a scatterplot in a color spectrum (rainbow, etc.).
  • These were traced over pixel images, so each file has a different number of xy coordinates (depending on the pixel resolution/image size that was traced).
  • All bird specimen images were downloaded from Phenome10k.org
  • All cephalopod specimens were traced from images published in:
    • Xavier, J. C. & Cherel, Y. 2009 Cephalopod beak guide for the Southern Ocean. British Antarctic Survey.
