Transmission lines are structures built to provide energy for the population's consumption. However, these lines have a direct or indirect impact on ecosystems, altering their composition and biotic interactions. The objective of this study was to determine the floristic composition, pollination, and dispersal syndromes in the transmission and subtransmission lines Las Flores-Erandique (SFE), San Pedro Sula Sur-Naco (TSPS), and Danlí-Chichicaste (SChD) in Honduras. To conduct the vegetation characterization, the present flora within the 16 × 16 m right-of-way area was inventoried, and herbs, shrubs, and trees were collected. To establish the relationship between habitat and floral traits, and determine the pollination syndromes, flower size and corolla colors were based, while dispersal syndromes were determined considering different characteristics in fruit morphology, fruit type, col...
