Ecological and physiological thermal niches to understand distribution of Chagas disease vectors in Latin America
In order to assess how triatomines (Hemiptera, Reduviidae), Chagas disease vectors, are distributed through Latin America, we analysed the relationship between the ecological niche and the limits of the physiological thermal niche in seven species of triatomines. We combined two methodological appro...
