Structure, diversity and the conservation value of tropical dry forests in highly fragmented landscapes

Although tropical dry forests are among the most degraded and fragmented biomes in the world, we still have a poor understanding of their basic ecological features and conservation status, particularly in the Neotropics. Here, we assess the diversity, composition, structure and conservation value of...
