Geographically structured variation in morphology is a common phenomenon in animals with environmental factors covarying with both latitude and biogeographic barriers having profound impacts on body size and shape. The Pacific blue-eye (Pseudomugil signifer) is a freshwater fish that lives along Australia’s east coast and occurs on either side of a terrestrial barrier, the Burdekin Gap. By quantifying the size and shape of males and females from 10 populations we found that Pacific blue-eyes… CONTINUE READING
