Evolution selects for traits that are of adaptive value and increase the fitness of an individual
or population. Numerical competence, the ability to estimate and process the number of …

The perceptual analysis of acoustic scenes involves binding together sounds from the same
source and separating them from other sounds in the environment. In large social groups …

As the last rays of sunlight disappear from the evening sky, a shallow marsh in Panama
begins to come alive with the calls of frogs and toads. Among these is a small yellow and …

Adult male baboons (Papio cynocephalus) give loud two-syllable'wahoo'calls during dawn
choruses, interactions between groups, when chasing females, and in aggressive …

Vocal interactions, such as call exchanges or chorusing, are common behaviours in many
animal species and their function has often been attributed to social bonding. However, few …

Translating a perceived number into a matching number of self-generated actions is a
hallmark of numerical reasoning in humans and animals alike. To explore this sensorimotor …

Where they co-occur, male anurans of different species may signal from diverse locations
and use vocalizations that differ spectrally. However, the relevance of such differences to the …

Many animals engage in dyadic vocal exchanges. Studying the patterns of vocal output and
spatial arrangement of individuals in these interactions can often reveal information …

The numerical sense of animals includes identifying the numerosity of a sequence of events
that occur with specific intervals, eg, notes in a call or bar of music. Across nervous systems …

Choruses of acoustically signaling frogs and toads are among the most impressive acoustic
spectacles known from the natural world. They are loud, raucous social environments that …
