The ocean consists of versatile domain lives which can be exploited for human health benefits because diversified secondary metabolites. Seaweeds, generally called macroalgae, are commonly found in the coastal region Bay Bengal. But none them were investigated properly their biological activities. Hence, this study was performed to investigate antioxidant, antimicrobial, cytotoxic and membrane ...
Aquatic ecosystems are the final absorbers of various pollutants, so require complex monitoring to control their condition. Macrophytes and other aquatic plants serve as reliable indicators hydro ecological state, they provide an integral assessment environment in time space. Changes chlorophyll a b content ratio rigid hornwort (Ceratophyllum demersum L.) leaves depending on water chemical para...
1. Patches of stable substratum in streams may be important refugia for benthic organisms during scouring floods. Streambed stone stability, packing and embeddedness were assessed within and adjacent to beds of the macrophyte Justicia americana in five Alabama streams. 2. The force needed to dislodge stones and embeddedness was about two times lower outside Justicia beds than within them. Signi...
Plastid matK gene sequences for 374 genera representing all angiosperm orders and 12 genera of gymnosperms were analyzed using parsimony (MP) and Bayesian inference (BI) approaches. Traditionally, slowly evolving genomic regions have been preferred for deep-level phylogenetic inference in angiosperms. The matK gene evolves approximately three times faster than the widely used plastid genes rbcL...
