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

By Javaria Altaf1*, Naureen Aziz Qureshi2, Syed Hammad Raza3, Muhammed Javed Iqbal Siddiqui4 Department of Zoology, Government College University Faisalabad, Pakistan Government College Women University Faisalabad, Pakistan Department of Botany, Government College University Faisalabad, Pakistan Department of Zoology, Government Postgraduate College, Samanabad, Faisalabad, Punjab, Pakistan Abstract Gastropods have never been studied in Punjab, Pakistan with reference to its diversity and distribution. Different ecological factors have been studied which affect the distribution of the snail in the agroecosystem of this region. Total number of 19290 snails specimens, were collected from different cropland areas of 24 villages of Faisalabad including sugarcane, wheat, fodder, vegetables fields and ditches. The specimens were identified on the basis of recent identification keys and diagrammatic description provided in them to understand the

By: Rey Y. Capangpangan, Nen Kenneth Pagapong, Cale P. Pineda, Pearl B. Sanchez Key Words: Speciation, Bioavailability, Environmental indices, Enrichment, Cluster. J. Bio. Env. Sci. 8(1), 1-16, January 2016. Abstract The contamination and potential ecological risk posed by heavy metals from thirteen (13) sediment samples from different sampling sites along the lower portion of Agusan River were analyzed and assessed using different pollution indices. The results obtained shows that the total digest concentrations of different heavy metals under investigation have the following order: Cd < Pb < Zn < Mn, for both first sampling periods. The speciation and distribution pattern have shown that significant amounts of all metals are present in the residual fraction. Similarly, oxide-bound and organic-bound fractions were found to be highly important for Zn and Mn while Cd and Pb were significantly associated in the residual and exchangeable fractions. The res
