Urbanisation can affect mating opportunities and thereby alter inter‐and intra‐sexual
selection pressures on sexual traits. Biotic and abiotic urban conditions can influence an …

Whether listening in a forest or on an open plain, by the side of a river or in the ocean, at the
outskirts of suburbia or right downtown, the Earth abounds with sounds. The use of the term …

Local adaptation of populations along elevational gradients is well known, but conclusive
evidence that such divergence has resulted in the origin of distinct species in parapatry …

Divergence in sexual signals may drive reproductive isolation between lineages, but
behavioural barriers can weaken in contact zones. Here, we investigate the role of song as a …

Phylogeographical analyses provide information about the role of evolutionary processes
underlying species diversity of the Neotropical montains. We used mitochondrial DNA …

Vocalizations in animals, particularly birds, are critically important behaviors that influence
their reproductive fitness. While recordings of bioacoustic data have been captured and …

Bird song is a culturally transmitted behavioural trait strongly tied to territory defence and
mate attraction in oscine passerines. Divergent song variations can appear in different …

Geographic isolation in rainforest refugia and local adaptation to ecological gradients may
both be important drivers of evolutionary diversification. However, their relative importance …

Many bird species, especially song birds but also for instance some hummingbirds and
parrots, have noted dialects. By this we mean that locally a particular song is sung by the …

In sexual communication, partners often form a duet, an exchange of species-and sex-
specific signals, and in such systems mate recognition is likely to be reciprocal. We studied …
