Abstract:Brain morphological variation is analysed through virtual endocasts in a highly diversified clade of caviomorph rodents belonging to the family Echimyidae. Diversification in brain size and shape is explored through geometric morphometrics and comparative phylogenetic analyses. The results indicate that brain shape is largely independent of general size and reveal different trends in brain size and shape. Fossorial Euryzygomatominae, arboreal Echimyini and the semi-aquatic Myocastorini Myocastor show high ence… Show more
