Features that make lizards sexy are resilient to stress
(PHYSorg.com Biology)

Physical traits and behaviors that make a lizard sexy-features used to attract potential mates and fend off competitors-may be important enough that they do not change in the face of stress. A new study by researchers at Penn State reveals that the blue and black badges on the throats and abdomens of male fence lizards-and signaling behaviors used to show them off-are not affected by low levels of stress-associated hormones, unlike many other traits. A paper describing the results appears in the journal Scientific Reports.
