Sample of intra- and interspecific wing shapes, quntified using 9 landmarks, from two species of cactophilic Drosophila (Diptera: Drosophilidae).
wingsA list containing:
a 9 x 2 x 263 array with the superimposed configurations
of landmarks marking veins intersections on the right wing of each specimen.
a vector of length 263 containing the centroid size of each specimen's wing.
a 3-column data frame with information about the taxonomic classification, host cactus, sex, line and replica of each specimen.
a list indicating how to connect the landmarks to create a wireframe.
a 2-column matrix containing the coordinates of the 9 landmarks, followed by the coordinates defining 9 curves curve describing wing morphology, to be warped using TPS interpolation.
This data set includes wing shape data from 263 experimentally bred specimens
belonging to two recently diverged cactophilic Drosophila species, D. koepferae
and D. buzzattii from northwestern Argentina. These two species show preference to
different host cacti (columnar cacti from the genus Trichocereus and prickly pears
from the genus Opuntia, respectively) and are considered morphologically cryptic
(usually, they can be recognized only from genital morphology). Accompanying data
include the centroid size of each wing, as well as information on the host cacti each
specimen was bred, its species, sex, isofemale line, and replica. Also included is a
template containing a series of curves describing wing outline and veins (created using
build_template2d), which will be warped using TPS interpolation.
