DESCRIPTION:Jumping spiders have long fascinated biologists and lay people
  alike with their visually striking\, sexually dimorphic color patterns an
 d courtship displays\, which suggest strong sexual selection in this group
 . Yet biologists have little understanding of the evolutionary forces shap
 ing what these signals actually look like. My group has been working in re
 cent years to try to understand what drives the evolution of the specific 
 color and achromatic contrasts found in salticid color patterns\, focusing
  on Mediterranean beardfooted and Australian peacock jumping spiders. What
  role do the color sensitivities of salticids and their predators play in 
 shaping the colors of their sexual signals? Can red coloration\, rather co
 unterintuitively\, be camouflaging? Do salticids possess an “aesthetic s
 ense” (or visual processing bias) for the spatial statistics of natural 
 scenes? If so\, does this drive sexual signals to evolve similar statistic
 s?
