Pied tamarins go multimodal in response to anthropogenic noise

Tainara Sobroza, Jacob Dunn, Marcelo Gordo & Adrian Barnett
Sounds produced by human activities are often loud and may mask acoustic signals used by other species for communication. To circumvent this, animals may use various strategies, including shifting modality completely or complementing acoustic information by also using another modality of communication. Here we tested the overlooked multimodal shift hypothesis using pied tamarins (Saguinus bicolor) as models. We predicted that in noisier areas the species would exhibit more scent marking behaviour (i.e., olfactory communication), while...
