Revised New World bioregions and environmental correlates for Chagas diseases vectors (Hemiptera, Triatominae)

This study objectively determined bioregions focused specifically on New World Triatominae, using clustering and ordination analysis We also identified indicator species by bioregion and investigated relationships among bioregions and environmental variables using redundancy analysis and multivariate regression trees. We delineated seven bioregions specific to Triatominae and linked each with indicator species. This result suggests more biogeographical structure exists than was revealed in earlier studies that were more general, subjective, and based on older taxonomic and distributional information. Precipitation, elevation, and vegetation were important variables in the delimitating bioregions. This implies that more detailed study of how these factors influence triatomine distributions could benefit understanding of how Chagas disease is spread.PMID:37944838 | DOI:10.1016/j.actatropica.2023.107063
