Spatial variation in avian bill size is associated with humidity in summer among Australian passerines
Background Climate imposes multiple selection pressures on animal morphology. Allen’s Rule proposes that geographic variation in the appendage size of endotherms, relative to body size, is linked to climatic variation, thereby facilitating heat exchange and body temperature regulation. Thus relatively larger appendages tend to be found in animals in warmer climates. Despite growing understanding of the role of the avian bill as an organ for heat exchange, few studies have tested the ecological...[Show more]
