Cesium (Cs) is a soil contaminant and toxic to the ecosystem, especially plant species. In this study, we have assessed potential of halophyte Sesuvium portulacastrum for its Cs tolerance accumulation. Thirty days old S. plants were subjected different concentrations (0, 5, 10, 25, 50, 150 mg·L−1 Cs) using cesium chloride. The biomass photosynthetic pigments not affected up 25 treatment while s...

Abstract Sesuvium is a genus of 14 to 17 species succulent plants, both annual and perennial, widely distributed in tropical subtropical regions. The has not yet been studied detail the Southern Cone (Argentina, Brazil, Chile, Paraguay Uruguay), which led misidentification numerous specimens as S. portulacastrum . As part ongoing floristic, taxonomic ecologic studies Argentina, we revise for Co...

Sesuvium portulacastrum L., (family: Aizoaceae), commonly known as “sea purslane” has long been used as food and traditional medicine. Traditionally plants are used in the treatment of epilepsy, conjunctivitis, dermatitis, haematuria, leprosy, purgative, fever, kidney disorders, and scurvy and also used to therapy toothache. Leaves have acidulous flavor of sorrel as well as antiscorbutic. The p...

Classic island biogeography theory predicts that very small islands, near the extreme lower end of the species area relationship, should support very few species. At times no species may be present, however, due to randomness in the immigration extinction dynamics. Alternatively, a lack of vegetation on very small islands may indicate that such islands do not contain the appropriate habitat for...
