Abstract Background We sketch our species identification tool for palm sized computers that helps knowledgeable observers with census activities. An algorithm turns an identification matrix into a minimal length series of questions that guide the operator towards identification. Historic observation data from the census geographic area helps minimize question volume. https://www.ngetikin.com/limited-value-Sapatilha-Infantil-Pampili-Bailarina-Laco-Duplo-Glitter-Prata-great-pick/
