The chromosome number and karyotype formula of interesting five genera six species Araceae from Thailand were studied, including Lasia spinosa —uncommon local Thai vegetable (2n=26, L6sm+L2st+Mm14+M4sm), Pistia stratiotes—common aquatic plant (2n=28, Lm10+Mm18), Pycnosphata palmata—rare endemic to Laos Lm12+L4sm+M6m+M2sm+M2st), Scittomaglottis calyptrata—rare in Lm6+L2sm+Mm6+Msm12), Typhonium g...

Snow-fed River Pinder -a tributary of River Alaknanda in central Himalaya was explored for fish assemblages and habitat specificity. Altogether 27 fish species were reported from three orders, four families and nine genera. Cypriniformes order was dominating followed by Siluriformes and Salmoniformes. Shannon-Weiner diversity index (3.09 to 4.10) and Simpson index of diversity (0.81 to 0.92) of...
