From: A reduction in ecological niche for Trypanosoma cruzi-infected triatomine bugs

Niche amplitude (bars) and inter-centroid distance (red arrows) of triatomines and its infected populations. Student’s t-tests were used to determine whether the niche amplitude between these two groups was significantly different. Inter-centroid distance is contrasted with the mean distance between centroid and random points that characterize the species niche (mean and EE are shown for each species and its infected populations)
