Assessment of Benthic Invertebrate and Planktonic Communities in Agba-Ndele and Ikiri Rivers, Rivers State, Nigeria (Published)
This study was to determine the heavy metal pollution study of fresh water Ecosystem in parts of Sombriore and Orashi River catchement area at Agba-Ndele and Ikiri River, Rivers State. Field sampling was conducted across several locations along the Rivers, with laboratory analysis carried out to measure water quality parameters, sediment characteristics, and heavy metal concentrations. Twenty-five species of benthic macro-invertebrates belonging to Seven (7) classes were identified in Agba- Ndele River, while twenty-nine (29) species were also recorded in Ikiri River, with the class insect having the highest percentage of 44.0% in Agba-Ndele followed by Gastropoda and Olgochaeta with (6.0%) each, Hirudinea and Crustacea (8.0%) each, and Chetellata and Arachnida (4.0%). Ikiri recorded percentage composition of (48.3%) in Insecta, followed by Oligochaeta and Gastropoda (13.8%) each, Crustacea (10.3%), Hirudinea (6.9%), while Chitellata and Arachnida recorded the same percentage of (3.4%) each. In terms of abundance, Agba-Ndele recorded (60.0%) of Oligochaeta, followed by Insecta (24.9%), Gastropoda (5.9%), Crustacea (4.5%), Hirudinea (2.5%), Chitellata (1.3%) and Arachnida had the least of (0.8%). Bacillariophyceae dominated the planktonic community, making up (83.9%) in Ndele River and (50.9%) in Ikiri River, zooplankton populations were represented by protozoa, copopoda and Nematoda. The diversity index were to assess species richness which recorded 1.029 in Agba-Ndele and 0.032 in Ikiri River. This search contributes significant to the understanding of aquatic biodiversity and the ecological impacts of pollution in the Niger Delta region.

Effectiveness of Reproductive Health Education among In-School Adolescents in Andoni Local Government Area of Rivers State, Nigeria (Published)
Reproductive health knowledge is significant in the growth and development of young people and this significantly impact on their educational and personal outcome as they proceed to adulthood. The aim of the study was to investigate the effectiveness of reproductive health education among in-school adolescents in Andoni Local Government Area of Rivers State. The study used a randomized control-group pretest-posttest research design. A multi-stage sampling procedure was used to randomly select samples for the study. Data was collected using pretested questionnaire with reliability co-efficient of 0.89 for knowledge questions. Data was analyzed using Statistical Package for Social Science (SPSS) for windows (Version 21). Data were presented using descriptive statistics to answer research questions and inferential statistics such as ANOVA was used to test hypotheses at 0.05 level of significance. Cohen criterion for interpretation of the eta value was used to interpret the effectiveness of reproductive health education with 0.01 as small effect, 0.06 moderate effect, and 0.14 as large effect. The study findings indicated that intervention group had a higher mean knowledge score 23.76±2.98 while the control group had a mean score of 22.31±22.3. The study recommended that teachers of senior secondary schools should periodically use mixed teaching method to better incorporate old and young adolescents to increase better reproductive outcomes.
