<p> Subspecies composition and genetic variation are important to the growth and survival of Largemouth Bass and information on these genetic characteristics is required for proper management of the species. In Puerto Rico, a genetic evaluation is needed to develop management plans for Puerto Rico reservoirs and maintain Florida Largemouth Bass at the Maricao Hatchery. Subspecies composition was characterized among reservoirs and the contemporary Maricao Hatchery broodstock in Puerto Rico, and metrics were compared between subspecies and hybrids among reservoir populations. Genetic variation and structure was determined and compared to Largemouth Bass populations in their native range. Florida subspecies were prevalent in all populations and non-introgressed subspecies seemed to be better adapted to the island than introgressed forms. Genetic diversity was lower in Puerto Rico populations and substantial genetic structure among populations was lacking. These results provide genetic information to guide future management and propagation of Largemouth Bass in Puerto Rico. </p>

This study examined the extent of natural resources management in one of the most densely populated districts in Kenya. The nature of land use, land ownership structure, and natural resource management strategies were examined. A theoretical assessment of the natural resources potential was conducted and the relationship between population and land resources was addressed. possible causes of the major problems in natural resources conservation and development were examined. In addition, possible implications of these problems and opportunities for securing a self-sustaining environment were studied. The approach followed was partly systematic based on the existing data sources, and partly conceptual, based on intuition and observation of some of the significant factors. The principle methods used were a review of the literature, supplemented with a reconnaissance field trip to the area, communication with people knowledgeable of the area, and the author's own experience and observations. The study indicated that the traditional practices of natural resources management have been disrupted by the adoption of a more intensive system of land tenure, and other political, social and economic factors. Two main recommendations were proposed: (1) that a viable development strategy to increase income earning opportunities through the utilization of existing natural resources and local labour resources be adopted, and (2) that top priority be given to addressing the problems of resource conservation and utilization in Murang'a district.
