Sample collection sites grouped by climatic/geographic similarities. Most of the sample-collection sites (dots) throughout Latin America were grouped into six regions (colors) by their climatic and geographic similarities: latitude, longitude, altitude (meters above sea level), rainy season, and the Köppen climate classification were considered. Lima, Peru, was not considered for the temporal distribution analysis because it could not be grouped in to one of the six regions.
