Abstract
Mountains are an ideal context to study species community and adaptation in relation with environmental changes such as temperature and vegetation profile. Such changes produce different ecological niches that can be source of local adaptations in the communities, like body size varying with elevation, for example. In this context, planthoppers (Insects, Hempitera, Fulgoromorpha) community and their species traits were studied along an altitudinal gradient in Mount Wilhelm (Papua New Guinea) to test niche and morphological trait conservatism in relation with environmental filtering.

Description of the data and file structure
This file is grouping the morphological traits and environmental data of planthoppers analyzed in the frame of the analysis of the adaptation of shape and size of Planthoppers along an altitudinal gradient on Mount Wilhelm (Papua New Guinea).
"Contour_11pts" file contains the 200 sliding points generated on the basis of eleven morphometrical landmarks of the forwings of all morphospecies of the sample.
"CsizeContour_11" file contains the size of the landmarks.
"facteur51PNG" file contains the altitude where the morphospecies were sampled. These three files are necessary to do the procruste analysis.
"Mesures_Fulgores" file contains the data to test de niche conservatism of the traits analyzed. Il includes forwings, rostrum and eye sizes, the ratio of forwings on eye and rostrum on eye. These ratio are the one used in the analysis as the size of traits may vary according to the body size.
All measurements on specimens are in milimetres. Altitudes are in metres above sea level.
File: Mesures_fulgores_dryad.zip
Description: The zip file Mesure_fulgores_dryad.zip contains 4 files of data used in the analysis. It includes "MesureFulgore" with altitude and morphological traits (forewings and rostrum) of the planthopper morphospecies used in the analysis of trait conservatism; "Contour11pts", "CsizeContour_11", and "Facteur51PNG" with landmarks, size and factors necessary for the procruste analysis. The files are formated to be used with tpsDig software.
Code/software
The files were analyzed using packages in R such as 'geomorph', 'ape', 'picante'
Insect sampling was set up along an altitudinal gradient in Papua New Guinea at eight different altitudes every 500 m extending from 200m to 3700m on Mount Wilhelm, and using Malaise traps, during two weeks between October and November 2012.
Forewing and rostrum size, as well as forewing shape were measured on all morpho-species to analyze morphological adaptation to altitude. Forewing shape was figured by 11 anatomical landmarks identified and associated with coordinates using tpsDig software. Forewing shape was analyzed using ‘Geomorph’ package on R. Procruste superpositions were carried out with ‘gpagen’ function. A Principal Component Analysis was performed on the shape coordinates in order to synthesize the information and identify forewings with similar shapes, using ‘gm.prcomp’ function.
