Testosterone and year-round territorial aggression in a tropical bird.
Testosterone (T) regulates avian behaviors such as song and aggression during the breeding season. However, the role of T in year-round territorial birds is still enigmatic, especially in tropical birds. Spotted antbirds (Hylophylax n. naevioides) defend territories in the Panamanian rainforest year-round but have low plasma T levels (0.1-0.2 ng/ml), except during brief periods of social challe...
متن کاملDelayed song maturation and territorial aggression in a songbird.
Asymmetries in competitive ability can determine the outcome of social interactions in animals and are often expressed through differences in sexual traits. Competitive ability (resource holding potential, RHP), trait expression and ultimately reproductive success may vary with an individual's age or experience. In some species, reproductively mature males delay acquisition of some adult traits...
متن کاملCountersinging as a signal of aggression in a territorial songbird
Neighbouring territorial songbirds often interact through countersinging, where birds sing in response to the singing of neighbours such that their song bouts are temporally related. Complex forms of countersinging such as song type matching or song overlapping appear to be correlated with aggressiveness and readiness to escalate confrontations. Less attention has been paid to the importance of...
متن کاملTerritorial aggression reduces vigilance but increases aggression towards predators in a cooperatively breeding fish
http://dx.doi.org/10.1016/j.anbehav.2016.01.008 0003-3472/© 2016 The Association for the Study of A In many species, aggressive individuals outcompete their less aggressive conspecifics for resources such as food and access to mates. Nevertheless, variation in aggression is maintained in populations, but the underlying mechanisms are not well understood. Here we tested the hypothesis that aggre...
متن کاملLethal intergroup aggression leads to territorial expansion in wild chimpanzees
of increasingly economical new-generation high-throughput DNA-sequencing technologies can be expected to permit genome-wide definition of the primary phy-regulated transcriptional network through the use of ChIP-seq and RNA-seq procedures. Proteomic approaches, such as mass spectrometric analysis, may provide an avenue for unravelling the current enigma of the capacity of the phy molecule to in...
