spotted amber ladybird, hippodamia variegata (goeze, 1777) (coleoptera: coccinellidae) is an important predator of aphids and some other insect pests. since shape and size variation may affect biological characteristics of an insect, multivariate analysis of shape variations in four geographically isolated populations of h. variegata (isfahan, shahrekord, shiraz, yasuj) was performed based on e...

the carob moth, ectomyelois ceratoniae (zeller), belongs to the family pyralidae and the subfamily phycitinae. in spite of some features of sexual dimorphism in size and shape in the order lepidoptera and the mentioned family, it has not been recorded in this species. in the current study, sexual dimorphism in the wing shape and size of carob moth on four hosts (pomegranate, fig, pistachio and ...

multivariate analyses of the morphological variation in five geographical populations of the pod borer, helicoverpa armigera (hã¼bner), was performed using 15 and 12 landmarks selected from the fore- and hindwings respectively. using their geometric morphometric characters (26 in the forewings and 20 in the hindwings), 287 and 277 images of fore- and hindwings were made respectively. analyses o...

Vibrissae (whiskers) are important components of the mammalian tactile sensory system, and primarily function as detectors of vibrotactile information from the environment. Pinnipeds possess the largest vibrissae among mammals and their vibrissal hair shafts demonstrate a diversity of shapes. The vibrissae of most phocid seals exhibit a beaded morphology with repeating sequences of crests and t...

BACKGROUND Few studies have looked into age-related variations in femur shape. We hypothesized that three-dimensional (3D) geometric morphometric analysis of the distal femur would reveal age-related differences. The purpose of this study was to show that differences in distal femur shape related to age could be identified, visualized, and quantified using three-dimensional (3D) geometric morph...
