DOI: 10.1002/bies.202000109
Abstract: Drosophila males sing a courtship song to achieve copulations with females. Females were recently found to sing a distinct song during copulation, which depends on male seminal fluid transfer and delays female remating. Here, it… read more here.

Nicotinic acetylcholine receptors in a songbird brain

DOI: 10.1002/cne.25314
Abstract: Nicotinic acetylcholine receptors (nAChRs) are ligand‐gated ion channels that mediate fast synaptic transmission and cell signaling, which contribute to learning, memory, and the execution of motor skills. Birdsong is a complex learned motor skill in… read more here.

DOI: 10.1002/dneu.22589
Abstract: Learned vocalizations are important for communication in some vertebrate taxa. The neural circuitry for the learning and production of vocalizations is well known in songbirds, many of which learn songs initially during a critical period… read more here.

Abstract: Abstract The soundscape acts as a selective agent on organisms that use acoustic signals to communicate. A number of studies document variation in structure, amplitude, or timing of signal production in correspondence with environmental noise… read more here.

DOI: 10.1002/ece3.3702
Abstract: Abstract Vocal traits can be sexually selected to reflect male quality, but may also evolve to serve additional signaling functions. We used a long‐term dataset to examine the signaling potential of song in dimorphic white‐throated… read more here.

DOI: 10.1002/ece3.5418
Abstract: Abstract Birdsong has long been considered a sexually selected trait that relays honest information about male quality, and laboratory studies generally suggest that female songbirds prefer larger repertoires. However, analysis of field studies across species… read more here.

A preliminary comparison of a songbird’s song repertoire size and other song measures between an urban and a rural site

DOI: 10.1002/ece3.8602
Abstract: Abstract Characteristics of birdsong, especially minimum frequency, have been shown to vary for some species between urban and rural populations and along urban–rural gradients. However, few urban–rural comparisons of song complexity—and none that we know… read more here.

DOI: 10.1002/ece3.8883
Abstract: Abstract Individual animals can react to the changes in their environment by exhibiting behaviors in an individual‐specific way leading to individual differences in phenotypic plasticity. However, the effect of multiple environmental factors on multiple traits… read more here.

Plasticity of signaling and mate choice in a trilling species of the Mecopoda complex (Orthoptera: Tettigoniidae)

DOI: 10.1007/s00265-017-2381-6
Abstract: Males of a trilling species in the Mecopoda complex produce conspicuous calling songs that consist of two motifs: an amplitude-modulated motif with alternating loud and soft segments (AM-motif) and a continuous, high-intensity trill. The function… read more here.

Abstract: In an eastern population of song sparrows (Melospiza melodia), song type matching occurs at above chance levels but does not signal aggressiveness. One explanation for the apparent ineffectiveness of matching as a signal is that… read more here.

DOI: 10.1007/s00265-019-2786-5
Abstract: Heterogeneous environments can create differential selection pressures among populations, which may result in the evolution of local adaptations. Premating isolation mechanisms may emerge due to limited movement among locally adapted individuals, thus further enhancing such… read more here.
