Abstract

Four types of bias in ecogeographical sampling are examined, and a discussion is presented on the negative effects they produced in a genebank collection of wild potatoes from Bolivia. Species bias consists of oversampling of a single representative; species-area bias is disproportionate sampling in a specific geographic location; hotspot bias is disproportionate sampling in an area of high diversity; and infrastructure bias is disproportionate sampling in areas near towns and roads.
