| ABSTRACT Coastal and marine environments are characterized by a lack of evident physical barriers or geographic isolation, and it may be difficult to understand how divergence can arise and be sustained in marine environments. The identification of 'soft' barriers is a crucial step towards the understanding of gene flow in marine environments. The marine catfishes of the family Ariidae are a demersal group with restricted migratory behavior, no pelagic larval stages, and mechanisms of larval retention, representing a potentially useful model for the understanding of historical processes of allopatric speciation in the marine environment. In the present study, two lineages of the Coco sea catfish, Bagre bagre , were recognized from their complete... |

| The phenotypic appearance of the head of animal species depends strongly on the shape of the skull. The present study has been carried out on morphological and radiographic characteristics of skull of the Indian Blackbuck. The skull comprised of cranial and facial bones. The cranial bones included occipital, sphenoid, ethmoid, interparietal, parietal, frontal and temporal. The occipital was a single bone surrounding the foramen magnum. The sphenoid was a single bone and situated between the occipital posteriorly and the ethmoid anteriorly. The ethmoid was a single bone laid ventral to the frontal and nasal bones. The interparietal was a small quadrilateral bone wedged in between the parietal anterio-laterally and the supraoccipital posteriorly. The... |

| The selection of eri silkworm ecorace with high yield and distinct in morphological character is necessary for variety improvement. Five eri silkworm ecoraces, SaKKU1, SaKKU2, SaKKU3, SaKKU4 and SaKKU5 were surveyed and derived in country or from academic cooperation in international level. All ecoraces were cultured using castor leaves of TCO101 variety as food plant at 25±2 °C, 80±5%R.H. Based on morphological characters, there were similar except body of the 5th instar larva of SaKKU1 was covered with white powder and ripe larva showing shiny dominant yellow color. Life cycles were also similar durations, 46-53 days (SaKKU1), 42-53 days (SaKKU2), 42-52 days (SaKKU3), 40-56 days (SaKKU4) and 41-52 days (SaKKU5). SaKKU1 had highest survival rate at larval... |
