This study is devoted to the analysis of the vegetation of coastal dunes in the region of Tlemcen. Results were obtained on these in general, including the biological and ecological. These results allowed us to individualize different phytosociological classes: The Cakiletea maritimae and Ammophiletea for cash at the beach; the Thero Brachypodietea and Quercetea ilicis in the sand dune and fixed dunes. Class Cakiletea maritimae and Ammophiletea grouped species of embryonic dunes. Thero Brachypodietea class includes species of sand dune. The class of Quercetea ilicis includes species of the dunes most advanced and most determined. Using phytosociological data and plant dynamics, we understand the evolution of the vegetation and its diversity.

Central and State Governments have dedicated television programmes based on agriculture, animal husbandry and fisheries which are telecast via public (Krishidarshan) and private television channels like ETV. Fisheries is a sunrise sector but there are not many studies on fisheries based television programmes. Accordingly, a study was carried out to assess viewers’ preference and develop a model for effective fisheries based television programmes. Study was undertaken in West Bengal as it has highest fish production. Viewers were asked to rank their preference of fisheries based television programmes. Aquaculture based topics had a Rank based Quotient (RBQ) value of 80.56 followed by fish processing (71.67) and fish health management (53.89). Fisheries scheme scored least (27.36). Hypothesis that viewers were applying same standard in ranking topics was accepted as value of Kendall’s Coefficient of Concordance (W) was 0.63. As X2 ≥ 118.8 with df = 9 has probability of occurrence under Ho of p < 0.001 it could be concluded that agreement among viewers is higher than it would be by chance. Based on the findings 4 P’s model for effective fisheries based television programmes consisting of presentation, programme content, programme telecast timing and policy issues was developed.

Bats make up a large proportion of mammalian diversity in Iran. Highest ranking sites for Rousettus aegyptiacus presence are located in Jahrom in southwest of Iran. Dominant vegetation in this region is Palm, Jujube, Figure, and Citrus. Ten specimens were captured using mist-net (4 cm mesh). Species were identified according to their morphological characters, and then autopsied and their digestive systems were observed for determination of diet types. Tongues were fixed in 10% formaldehyde, samples were taken from tip, middle and hind tongue and placed in tissue processor and dehydrated in graded series of ethanol (70%-100%), then impregnated with paraffin and serial Sections (4μ thickness) were prepared. sections were subjected to Haematoxylin and Eosin (H&E) stains and mounted on binocular microscope and micrographs were taken with digital camera. Presence of seeds, pieces of leaf and fruit in their gut and feces showed their frugivory diet type. Elongated and movable tongue and tine keratinized epithelium especially on ventral surface of tongue, numerous and different types (4 types) of papilla on the dorsal surface of tongue in different locations and orientation were seen in this species. Hyaline cartilage was observed in tip of tongue.
