Strategic reduction of help before dispersal in a cooperative breeder.
In cooperative breeders, sexually mature subordinates can either queue for chances to inherit the breeding position in their natal group, or disperse to reproduce independently. The choice of one or the other option may be flexible, as when individuals respond to attractive dispersal options, or they may reflect fixed life-history trajectories. Here, we show in a permanently marked, natural pop...
متن کاملSex-Biased Dispersal at Different Geographical Scales in a Cooperative Breeder from Fragmented Rainforest
Dispersal affects both social behavior and population structure and is therefore a key determinant of long-term population persistence. However, dispersal strategies and responses to spatial habitat alteration may differ between sexes. Here we analyzed spatial and temporal variation in ten polymorphic microsatellite DNA loci of male and female Cabanis's greenbuls (Phyllastrephuscabanisi), a coo...
متن کاملTowards the Development of a Socially-Informed, Process-Oriented Model of Research in Metadiscourse
Since the early development of interest in the interpersonal dimensions of academic communication in the 1980s, the analytic potentials of the concept of metadiscourse have motivated a large number of investigations. Although these analytic potentials have facilitated the study of diverse academic genres, there has always been a risk of detachment of textual analyses form the contextual origins...
متن کاملDispersal costs set the scene for helping in an atypical avian cooperative breeder.
The ecological constraints hypothesis is suggested to explain the evolution of cooperative breeding in birds. This hypothesis predicts that the scene for cooperative breeding is set when ecological factors constrain offspring from dispersal. This prediction was tested in the atypical cooperative breeding system of the long-tailed tit, Aegithalos caudatus, by comparing the degree of philopatry a...
