Fruit and flower availability affect bird assemblages across two successional stages in the Atlantic Forest

The Atlantic Forest is highly heterogeneous, with successional stages inducing shifts in food resources for birds. We investigated fruit and flower availability across two different successional stages in a continuous forest and the implications for bird communities. We sampled three sites in primary forest and three in second-growth forest. We established four plots (10 x 10 m) in each site and estimated the availability of zoochorous fruits...
