Author Information Genelyn G. Madjos  from the Institute of the  Department of Biological Sciences, College of Science and Mathematics, Western Mindanao State University, Zamboanga City, Philippines Journal Name Journal of Biodiversity and Environmental Sciences | JBES Abstract Nickel miningposed a serious environmental problem due to run-offs and tailings. To address this, current techniques include excavation, chemical stabilization and soil flushing, but these methods are costly and impractical. One of the ecologically accepted treatments is phytoremediation. With the capacity of Centella asiatica (gotu kola) to thrive in moist soils with domestic effluents, this present study sought to evaluate its phytoremediation potential by employing an experimental design with three replicates of: (a

The study was carried out as an intensive sampling survey in the intertidal zones of Sarangani Province (Glan and Maasim), relying on the low tide to determine the total species number, relative species abundances, frequency and spatial distribution of seagrass.Eight Species of seagrasses andnineteen species of macroalgaewere gathered. These have been the sampling sites of researchers, most especially students, for its reputation of having diverse distribution of such aquatic plants. A total of fifty sampling plots were laid using quadrats; ten quadrats were arranged alternately with a five-meter disparity between each plot, placed perpendicularly to the shore. The study identified species of seagrass belonging to the family Potamogetonaceae and Hydrocharitaceae. Nineteen species of macroalgae were identified from where either seagrass was present or absent and categorized under the family of Dasycladaceae, Ulvaceae, Halimedaceae, Caulerpaceae, Dictyotaceae, Sargassaceae, Galaxauraceae, Wurdemanniaceae, Gelidiaceae, Gracilariaceae and Cryptonemiaceae.Seagrass. Biodiversity indices such as dominance, Shannon’s diversity, evenness, species richness and number of individuals were also determined using PAST software. Distribution analysis revealed the three highest number of species among the eightseagrass species wereEnhalusacoroides, Haloduleuninervis and Thalassiahemprichii-such werecommon in both sites. The Padina minor from the nineteen identified macroalgaespeciesin the algal community has the most number of species. There are great indications of seagrass and macroalgae presence with its distribution when proper sampling procedure is done. Researchers strongly recommend that physicochemical such salinity and sedimentation and also correlation on distribution of species be studied further.

Let’s get some knowledge about this research.  Abstract Coastal area of East Java Sea has long been threatened by industrial source pollution, mangrove conversion into shrimp culture, over fishing, destructive fishing, sedimentation, and coastal settlement. Heavy-metal is probably the most threat that directly influ
