Topographic Barriers and Lowland Corridors Structure Gene Flow in the Chagas Vector Rhodnius pallescens Across the Isthmian Forests

Journal of Biogeography, Volume 53, Issue 7, July 2026.
ABSTRACT Aim Biogeographic processes can profoundly shape the connectivity and evolutionary potential of arthropod disease vectors. We investigated how Panama's ecological and topographic transitions structure populations of the kissing bug Rhodnius pallescens, the primary vector of the Chagas disease agent Trypanosoma cruzi in the region.
