The photosynthetic responses of clusterbean (Cyamopsis tetraganoloba) cotyledons exposed to UV-A, UV-B or UV-A + UV-B radiation for 1 h daily until day 10 have been compared. The loss in the rate of O2 evolution and CO2 assimilation (Pn) are incommensurate with each other in both UV-A and UV-B exposed samples indicating the occurrence of loss in photostasis of photosynthesis by these two radiation bands. The alteration in redox status of QA further suggests about a loss in redox homeostasis in the photosynthetic electron transport chain. However, both photochemical efficiency of PS II and Pn are well maintained in UV-A + UV-B exposed cotyledons in spite of reduction in water-use efficiency. The acclimatization of clusterbean cotyledon to UV-B radiation in the presence of UV-A has been attributed to accumulation of flavonoids, increase in stomatal conductance (gs) and reduction in functional size of PS II.

First records of: viper moray, Enchelynassa canina (Quoy et Gaimard, 1824); vermiculated blenny, Entomacrodus vermiculatus (Valenciennes, 1836); cardinalfish, Apogon fleurieu (Lacepède, 1802); and orangelined cardinalfish, Archamia fucata (Cantor, 1849) in the waters along the east coast of India are herewith documented. This record increases the knowledge on the richness of the Indian marine reef-associated fauna and may suggest a range extension of the geographical distribution of the mentioned species from the western Indian waters to east coast of India.

A specimen of garden eel, Heteroconger tomberua Castle et Randall, 1999, was collected from the traveling water screen of sea water cooling system of the Madras Atomic Power Station (MAPS), Kalpakkam located along the east coast of India. Previously, H. tomberua was recorded in Fiji, Pacific Ocean. The presently reported record greatly extends the fish range to the Indian Ocean and constitutes a new addition to the ichthyofauna of India. The described specimen of H. tomberua, with its total length 55.9 cm, seems to be the largest ever found.
