Effects of Ant- Fruit Interactions Deforestation

by Maithili Joshi

Biodiversity within an ecosystem has mutualistic and symbiotic relationships within that environment. The results of deforestation can be dramatic to these relationships, especially in cases with frugivores. The relationships between frugivores and fallen fruit are what help disperse seeds across the forest floor, which also helps the process of germination. In this study, Bieber et al. (2014) analyzed the mutualistic interactions between ants and fallen fruit in São Paulo State, SE Brazil. The scientists were examining the difference in interactions between disturbed and undisturbed forests. They compared the richness of ants at each fruit, species density per station, frequency of specific ant groups, frequency of fruit and pulp removal, and distance of fruit removal. The study was conducted using four disturbed forests, and four undisturbed forest areas. In these areas, there were thirty sampling stations with synthetic fruit placed 10 m apart from each other to ensure independent discoveries. The fruit were placed on a white sheet of paper within a wire cage to ensure that vertebrates did not access the fruit at each sampling station. Continue reading
