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 present study intends to evaluate the dune slacks vegetation inside the sand dune ecosystem of Egypt. It represented by fives slacks in three different habitats: two brackish, two saline and one cultivated slacks in North Sinai.
The density and cover of species were measured in 26 stands, 2X2 m2 each. The total number of their cover was 56 species. The richest habitat was the brackish slacks followed by cultivated and saline slacks respectively.
By using two way indicator species analysis (TWINSPAN) it gives 12 groups as follow (5 cultivated groups, 4 brackish groups, and 3 saline groups). By using ordination methods CCA we found highly correlation between cultivated and brackish slacks and the fine soil particles silt and clay and the percentages of organic matters; and salinity, chlorides and sodium salts and the saline slacks.
Line Regression between the number of species and the area of stand is positive in case of cultivated and brackish slacks, and negative between saline slacks and its areas.

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
