An example is provided in Fig. 9, in which known occurrences of a species endemic to Mexico {Buarremon virenticeps) are used to predict its geographic distribution. Extensive testing of the predictive accuracy of models developed using this approach have amply demonstrated its utility (Peterson & Cohoon 1999, Peterson et al. 1999, 2002a,b, Peterson 2001, Peterson & Vieglais 2001, Anderson et al. 2002a,b, in press, Feria & Peterson 2002, Stockwell & Peterson 2002a,b). Species richness, endemism and conservation There are many potential applications of this information resource and technology to the conservation of biodiversity. For single-species prioritisations, Fig. 10 provides an illustration of the geographic situation of the Oaxaca Sparrow Aimophila. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Ornithologists' Club.
