Abstract EN
Seasonality can cause severe bottlenecks in natural populations, even leading to local extinction.
Large variation in resource availability may explain the bottlenecks, but the role of these variations is still poorly understood.
The goal of this study was to analyze if temporal variations in the guild of drosophilids breeding in fruits of Mauritia flexuosa (Arecaceae) can be explained by the shortage of this resource during the dry season.
Fruits of M.
flexuosa were collected over one year in a gallery forest located in the Central Brazilian Savanna.
The drosophilid assemblage varied over time, with a lower density of species and of individuals in the dry season, when the percentage of colonized fruits was also smaller.
These findings suggest that although the fruits were available during the dry season, they were underused.
This way, the resource availability does not seem to regulate the community in the dry season.
