International Network for Natural Sciences - Research Journal Publisher: Population Structure and Threats to Sustainable Ma... : By: T.H. Dauda, S.O. Jimoh, I.O. Azeez This study was conducted to assess population structure and threat to the sustainable management of woody species in the various ago-ecosystems in Dutsin-Ma Local Government Area (LGA) Katsina State, Nigeria. Purposive and stratified random sampling techniques were used to collect data from 21 randomly demarcated 100m × 100m sample plots. All woody plant species found in the sample plots with stem diameter >2 cm at 20cm above ground, were recorded. Population structure was summarized by diameter classes. For the identification of threats, field and questionnaire surveys were used. A total of 50 questionnaires were distributed at ten questionnaires per ward in five out of the 11 wards in the LGA.

The objective of this study was to determine the community knowledge in using plants for medicine and healing agent in Cikondang Indigenous Village, district Bandung. Emic and ethical approaches were used to describe the community knowledge along with the scientific explanations. The data of community knowledge in using plants for medicine and healing agent was collected from respondents as many as 87 families and 4 key informants through interview techniques. The medicinal ...

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 ...

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...

AMD has a pH of 3.0 and limited nutrients content. Therefore, before being released into the environment, it requires pH modification to deserve for growing of aquatic plants. This study aimed to determine the effect of pH on the growth of water hyacinth. AMD was collected from coal mining in Tanah Laut, South Kalimantan and limestone was taken fro...
