Intrinsic postzygotic barriers can play an important and multifaceted role in speciation, but
their contribution is often thought to be reserved to the final stages of the speciation process …

Animal acoustic communication often takes the form of complex sequences, made up of
multiple distinct acoustic units. Apart from the well‐known example of birdsong, other …

To understand modern principles of sustainable management and the conservation of
wildlife species requires intimate knowledge about demography, animal behavior, and …

The power of sexual selection to drive changes in mate recognition traits gives it the
potential to be a potent force in speciation. Much of the evidence to support this possibility …

The voices of birds have always been a source of fascination. Nature's Music brings together
some of the world's experts on birdsong, to review the advances that have taken place in our …

The function of bird song is closely linked to sexual selection. A fundamental question
regarding the evolution of sexually selected male signals is how their honesty is maintained …

The study of bird song dialects was once considered the most promising approach for
investigating the role of behaviour in reproductive divergence and speciation. However, after …

The oscine passerines, or 'songbirds', are one of the few animal taxa in which individuals
learn their vocal signals. Recent comparative studies reveal a remarkable diversity of song …

The spatial distribution of genetic markers can be useful both in estimating patterns of gene
flow and in reconstructing biogeographic history, particularly when gene genealogies can …

Given that evolutionary divergence in mating signals leads to reproductive isolation in
numerous animal taxa, understanding what drives signal divergence is fundamental to our …
