| Serrapinnus potiguar, new species, is described from the rio Ceará-Mirim, a coastal drainage in the Rio Grande do Norte State, northeastern Brazil. The new species is distinguished from the other species of the genus by the shape and arrangement of the ventral procurrent caudal-fin rays of the sexually dimorphic males; where the hypertrophied elements present the shape of a series of scimitars arranged radially, forming a semi-circle on the ventral margin of the caudal peduncle. Furthermore, the new species is diagnosed from S. heterodonand S. piaba, sympatric congeners from the northeastern Brazilian drainages, respectively by the presence of incomplete lateral line and teeth bearing at most five cusps. |

| Morphological variation of the ramus mandibulae of wild Sus scrofa was described and correlated to sex and age differences. Young forms (n=27, 15 males, 12 females) and adults (n=23, 13 males, 10 females) were analyzed through Geometric Morphometrics (2-D) to assess differences between groups. We found significant differences between age- and sex-related shape variations at ramus mandibulae level. Young wild boars present bulky angular process with backward oriented coronoid process, while adults show slender jaw vertical ramus, and orthogonally oriented coronoid process. The ramus mandibulae in female wild boars is more robust and bulky than in males. The morphological changes between young and adult forms are related to alterations in the osteo-muscular... |

| The aim of this study was to investigate the sexual dimorphism in permanent maxillary central incisor in Kosovo Albanian population using crown linear diameters, crown module (CM) and crown index (CI). The study sample consisted of 204 dental students, selected from the Dental School, Faculty of Medicine at University of Prishtina, Republic of Kosovo. The measurements of mesiodistal (MD) and buccolingual (BL) crown diameters of left and right permanent maxillary incisor (MCI) were taken in a dental casts using electronic digital caliper Boss, Hamburg Germany, with accuracy± 0.01 mm. The descriptive statistics, t-test and percentage of sexual dimorphism in crown linear diameters and dental indexes of maxillary central incisor were calculated. The results... |
