Assessment of Ecological Status and Tree Diversity in Watershed Area of Dandi Local Government Area in Kebbi State, Nigeria

This study assessed the ecological and tree diversity status of watershed area of Dandi local government area in Kebbi state using systematic sampling technique. Three transects of 300 m long were laid at 100 m intervals. On each transect, six sample plots of size 50 m x 50 m (0.25ha) were alternately laid at 50 m intervals. A total of 18 sample plots will be used for the study. Diameters at breast height (Dbh) of all the trees found in the plot with Dbh ≥ 5cm will be measured. Fourteen tree species belonging to 10 genera and 8 families were identified. Borassus aethiopum of the family Arecaceae was the most abundant species in the area with a relative density (RD) and diversity index (DI) of 0.296 and 0.08728 respectively. This was followed by Cocos nucifera in the Arecaceae family also, with RD and DI of 0.192 and 0.03662 respectively. Daniella oliveri of the family Fabaceae was the least represented species with RD and DI of 0.0018 and 0.00002 respectively. The overall tree species richness in the area was 0.0052

Effects of Mineral Composition of Different Wood Wastes in Ibadan on Proximate Composition of Lentinus Squarrosulus (Mont.)

Lentinus squarrosulu (Mont.) is one of the cultivated indigenous edible mushrooms that are available in Nigeria.   Recently, there has been growing crave to crop wild edible mushroom species that have   potential economic values. Mushrooms can be an alternative source of protein especially for commoners in the society. Hence, the objective of this paper is to evaluate the effect of mineral composition of five wood wastes- Triplochiton scleroxylon, Cordia milleni, Vitellaria paradoxa, Pouteria altissima and Anogeissus leiocarpa different wood wastes on L. squarrosulus (Edible Mushroom) cultivation for their consequences on the growth, yield and proximate analysis. Data obtained reveal Carbon/Nitrogen ratio of 11.59, composition of Magnesium (0.035 mg), Potassium (0.053 mEq/l), Manganese (0.0013 mg), Copper (0.00050 g/m3), Iron (0.00275 mol/L), Phosphorus (0.027 mmol/L), Organic carbon (32.10 mg/L C), Organic matter (55.3 t/ha) and total nitrogen (2.77 mg/L) contributed greatly to the high crude protein, fats and ash contents of mushroom   cultivated  on T. Scleroxylon. However, insignificant contents of sodium (0.2 mg), Calcium (0.2 mmol/L) and Magnesium (0.013 mg) in Pouteria altissima led to the general inadequate performance of L. squarrosulus in yields. The percentage fresh mean weight of L. squarrosulus ranged from 9.13 g – 19.00 g. The highest value was produced by T. scleroxylon followed by P. altissima, V. paradoxa, C. milleni while A. leiocarpa gave the least

Family Cohesion and Level of Communication Between Parents and their Adolescent Children

This study investigated the level of communication between parents and their adolescent children and how such communication affects family cohesion. A sample of 200 subjects made up of adolescents and parents were selected through cluster, stratified and random sampling techniques from ten Local Government Areas in Kwara state. A questionnaire titled communication between parents and adolescents Questionnaire (CBPAQ) was administered to elicit relevant data from the respondents and the data were analyzed with the use of frequency counts, simple percentages and chi-square (X2) statistical analysis. The result established that a significant relationship exist between communication and family cohesion. It also revealed the level of communication between parents and their adolescent children to be above average. Some of the factors affecting level of communication were identified and appropriate recommendations were made. Keywords: Family cohesion, communication, parents, Adolescent children.
