Abstract: This study assessed the conservation status of crocodiles in Okomu National Park, Nigeria, and the impact of environmental degradation on biodiversity. A multi-faceted approach was used to gather data, including field surveys, bushmeat market surveys, oral interviews, and documentary analysis. The field survey yielded no results, while nearby bushmeat market surveys recorded 30 dwarf crocodiles at Ekiuwa Market and 17 at Oba Market. Demographic data from 35 park staff revealed that 74.3% were male and included various roles such as field researchers and park rangers. Results indicated the presence of dwarf crocodiles in the park, with Chi-square analysis showing no significant difference in responses regarding their safety and disturbance. The sale of dwarf crocodiles in nearby markets highlights potential poaching threats to conservation efforts. Factors threatening crocodile species included major issues like hunting, poaching, and habitat destruction, while water quality and food availability posed minor threats. Documentary evidence indicated that human activities, such as logging and agricultural clearance, significantly impact environmental degradation in the Niger Delta. The findings underscore the need for conservation strategies, including habitat protection, anti-poaching measures, pollution control, prohibition of agricultural activities and community engagement to safeguard the dwarf crocodile population and biodiversity in Okomu National Park.

Abstract: The Agricultural Research Center of Adami Tulu, Ethiopia, conducted experiments to artificially rear bee queens using Morris Board and Splitting-methods. Six colonies of bees were randomly assigned to conduct experiments. In three honeybee colonies, the queens were isolated during the experiment and remained in Brood Chamber/Box using a screen board, while the remaining colonies were split to rear the queens. The two methods of breeding the honeybee queen show a very significant difference (P0.001) in the number of cells constructed, the number of sealed honeybee queen cells, and the number of egg/producing honeybee queens. In addition, there was very significant difference (P0.001) between the two methods used in the cost-benefit aspect. The honeybee queen was found to have cost significantly reduced when raising the honeybee queen with Morris boards compared to a split one. However, the current experiment does not have a significant difference in honeybee bred populations and honey yield, and other honeybee colonies receive young queens raised in two ways. It follows that Morris-board's honeybee breeding techniques are highly effective and cost-effective in producing honeybee queens for the multiplication of honeybee colonies to the best of ordinary farmers' skills and financial capabilities. Therefore, demonstration of technology is of principally important considering the country's widespread biophysical differences in order to exploit the technology in an attempt to artificially grow honeybee queens.
