In this article, we discuss the effect of salinity on the viability and decomposition of Eichhornia crassipes plant under normal photoperiod, dark condition and physiological response. Highest concentration of total organic carbon (27.43 mg C l-1) was recorded in 15 psu salinity after 45 days. The TOC output was more in case of leaf (3.6 mg C l-1) than petiole (2.39 mg C l-1) under dark condition, after 21 days in freshwater. Salt stress was found to enhance the superoxide dismutase activity at 20 psu in both leaf and petiole. Enzyme activity declined when salt-stressed plants were transferred to nutrient enriched freshwater. This indicated that 20 psu could be a plant's salt tolerance limit. The potential transfer test conducted in this study showed that Eichorrnia introduction through shipping activities is less likely.Keywords

A study of the temporal effect on the abundance and diversity of intertidal rocky shore macroalgae revealed that there are ~70 species in the intertidal rocky shore of Anjuna (60 species) and Vagator (52 species) in Goa, India. Results showed that premonsoon (May) and post-monsoon (December) seasons favoured high species richness and abundance in both the study sites. In both cases, species diversity was low during the monsoon months (July and August). The study showed that low diversity might be a monsoonal effect and it coincides with the growth of Ulva and Porphyra species. The growth of opportunistic annuals brings about an ephemeral dominance of the macroalgal community by annual macroalgae. The driver is believed to be the nutrient influx from surface run-off, change in salinity and temperature due to high precipitation. The study showed that monsoon could have a role on the macroalgal community dynamics, and there was a strong correlation between diversity and biomass.Keywords
