Does leadership indicate male quality in Neoconocephalus katydids?

Editorial: The Evolution of Rhythm Cognition: Timing in Music and Speech

“…Common foci are the relationship between synchronization and prosociality (Gebauer et al, 2016; Reddish et al, 2016; Rennung and Göritz, 2016; Tunçgenç and Cohen, 2016; Cirelli et al, 2017), and different forms of rhythmic behaviors in interaction (Large and Gray, 2015; Ravignani, 2015; Yu and Tomonaga, 2015; Ellamil et al, 2016; Gebauer et al, 2016; Greenfield et al, 2016; Moore et al, 2016; Schirmer et al, 2016; Wallot et al, 2016; Murphy and Schul, 2017). …”

Leader preference in Neoconocephalus ensiger katydids: a female preference for a nonheritable male trait

“…The production of leading calls is often correlated with costly male call traits, potentially resulting in the proportion of chirps that a male leads serving as an honest indicator of his quality or condition (Greenfield & Roizen, ; Hartbauer et al ., ; Richardson et al ., ). However, the production of leading chirps was not correlated with his quality in any species tested so far (Hartbauer et al ., ; Richardson et al ., ; Murphy & Schul, ). Each of these studies measured male quality using several quality indicators such as body size and mass.…”

“…Heritability of the preferred male trait would also result in females gaining a ‘sexy‐sons’ benefit from mating with leading males (Kokko et al ., ). The repeatability of leadership ability, which sets the upper limits on heritability for this trait (Boake, ; Falconer & Mackay, ), was measured in two species with leader preference with differing results; within‐night repeatability was low in Ephippiger diurnus katydids, but was high in Neoconocephalus ensiger katydids (Party et al ., ; Murphy & Schul, ). However, high repeatability does not indicate high heritability, particularly for traits that are strongly affected by environmental conditions (Dohm, ); heritability, to our knowledge, has not been measured heretofore for any species with a leader preference.…”

The Evolution of Rhythm Cognition: Timing in Music and Speech

“…The relationship between rhythm and sociality has seen a steady increase in research and has probably been the most investigated topic over the last 2 years (Large and Gray, 2015;Yu and Tomonaga, 2015;Ellamil et al, 2016;Gebauer et al, 2016;Greenfield et al, 2016;Moore et al, 2016;Reddish et al, 2016;Rennung and Göritz, 2016;Schirmer et al, 2016;Tunçgenç and Cohen, 2016;Wallot et al, 2016;Bishop and Goebl, 2017;Chang et al, 2017;Cirelli et al, 2017;Hannon et al, 2017;Knight et al, 2017;Mogan et al, 2017;Murphy and Schul, 2017;Rorato et al, 2017;Myers et al). Common foci are the relationship between synchronization and prosociality (Gebauer et al, 2016;Reddish et al, 2016;Rennung and Göritz, 2016;Tunçgenç and Cohen, 2016;Cirelli et al, 2017), and different forms of rhythmic behaviors in interaction (Large and Gray, 2015;Ravignani, 2015;Yu and Tomonaga, 2015;Ellamil et al, 2016;Gebauer et al, 2016;Greenfield et al, 2016;Moore et al, 2016;Schirmer et al, 2016;Wallot et al, 2016;Murphy and Schul, 2017).…”
