it has been postulated that the building of the manjil and tarik dams on sefidroud river has led to the body shape variation of capoeta gracilis in up- and downstream populations due to the isolation. in this study, geometric morphometric approach was used to explore body shape variations of capoeta gracilis populations in up- and downstream manjil and tarik dams in sefidroud river from south o...

this study investigates skull variation in persian jird, meriones persicus (blanford, 1875) in relation to the geoclimatical conditions across its distribution range. the pattern of correlations between geoclimatical variables and geometric shape descriptors for 221 ventral crania was studied by landmark-based geometric morphometric techniques. the covariation between shape and geoclimatical va...

1 This research is supported by the President Foundation of the Institute of Acoustics, Chinese Academy of Sciences (No.98-02) and “863” High Tech R&D Project of China (No. 863-306-ZD-11-1). ABSTRACT Visual feature extraction method now becomes the key technique in automatic speechreading systems. However it still remains a difficult problem due to large inter-person and intraperson appearance ...

The shape diversity among populations of Scartelaos tenuis (Day 1876) from five stations (194 specimens) in the Persian Gulf, Strait of Hormuz (Qeshm Island), and the Sea of Oman were investigated. The shape variation was assessed by geometric morphometrics, using 14 morphological landmarks. The two sexes were not distinguishable by the shape. Fish samples were classified into two distinct grou...

Phenotypic variations in fish body and scale shape were investigated among the three populations of Aphanius dispar (Rüppell, 1829)in Southern Iran through the use of landmark-based geometric morphometric analyses. This species is widely distributed in the region, and therefore, considerable morphological variations exist among the geographically allopatric populations. Based on the Principle C...

Nutlets of 20 taxa of the tribe Marrubieae were examined by scanning electron microscopy (SEM) and detailed descriptions of nutlet micromorphological features for all examined taxa are provided. The nutlets exhibited variation in size, shape, color and surface sculpturing. The nutlets shape of most species studied is ovate, but rounded, broad ovate, elliptic, lanceolate, triangular and oblong c...

background: forensic odontology plays important role in identification of human remains in mass disasters such as air crash, tsunami, and accidents. palatal rugae act as an ideal requisite for human identification as they are present in all victims and are resistant to changes such as aging and trauma. the study aimed to analyze differences in shape and number of palatal rugae in population fro...
