Randomized trial assesses vertical and seasonal effects on butterfly diversity in Brazilian dry forests, suggesting ecological implications for conservation.
Key Points
This research evaluates how vertical stratification and seasonal changes influence butterfly communities in a tropical dry forest.
Sampling conducted monthly over one year in northern Espinhaço Range, Brazil.
Twenty 25 × 4 m plots set with two traps each for understory and canopy observations.
Measurements included temperature, humidity, light, precipitation, and zoochoric fruit availability.
Recorded 2,166 individuals from 51 species, with distinct dominance in understory (Hamadryas februa) and canopy (Biblis hyperia nectanabis).
Species richness peaked in hot months, while abundance peaked two months after the rainy season.
Distinct seasonal peaks in subfamilies and tribes, indicating temporal niche partitioning.
