Data from: Evolution of Acoustic and Visual Signals in Asian Barbets
负责人:
Gonzalez-Voyer, Alejandro
关键词:
摘要:
signals can be costly to produce, trade-offs may exist between different types of signals. Here, we apply phylogenetic comparative analyses to study
Data from: Costs and constraints conspire to produce honest signalling: insights from an ant queen pheromone

摘要:
Signal costs and evolutionary constraints have both been proposed as ultimate explanations for the ubiquity of honest signalling, but the interface

摘要:
The concept of a macroevolutionary trade-off among sexual signals has a storied history in evolutionary biology. Theory predicts that if multiple
Data from: Mating opportunities and energetic constraints drive variation in age-dependent sexual signalling

摘要:
When males repeatedly produce energetically expensive sexual signals, trade-offs between current and future investment can cause plasticity in age
Data from: A test of the eavesdropping avoidance hypothesis as an explanation for the structure of low amplitude aggressive signals

摘要:
its in addition to low amplitude that lead to quiet signals transmitting less effectively through the environment compared to broadcast signals. The “warbled” soft
