Single-‐species PrioriYzaYon of Sites for Survey
Single-‐species Priori/za/on of Sites for Survey Abio/c niche Area presen/ng appropriate combina/ons of abio/c and bio/c condi/ons (= poten&al distribu/on) Actual geographic distribu/on (abio/c and bio/c condi/ons fulfilled, accessible to dispersers) Accessibility Bio/c interac/ons Chameleon Distributions in Madagascar Known and Predicted Distributions Furciferverrucosus oustaleti Furcifer pardalis Brookesia stumpffi Disjunct Suitable Areas Not Inhabited Subsequent expeditions Furcifer oustaleti Furcifer verrucosus Furcifer pardalis Brookesia stumpffi 7 new species in 3 expeditions to these sites; only 1 new species in sites not on this list Funisciurus Squirrels: Future Project Funisciurus Funisciuruscarruthersi anerythrus Funisciurus congicus Funisciurus leucostigma Funisciurus pyrropus Funisciurus lemniscatus Peterson, A.

Chromosome homogeneity in populations of Triatoma brasiliensis
populations were reported only from Pernambuco and Bahia, respectively, occupying peridomiciliary and sylvatic ecotopes. The melanica population, from the North of Minas Gerais, was only
