4.2. Soundscape dynamics
4.2.1. Wet versus dry season
As expected, the acoustic complexity registered during the wet season
was much higher than in the dry season at both sites. The wet season
in Brazil coincides with breeding season of insects, amphibians and
birds; consequently, animals are more acoustically active (Aichinger,
1987; Haddad et al., 1992; Rodrigues et al., 2005). This result was confirmed
by the species count, with a greater number of species from all
of the animal groups being detected during the wet season
