The course exposes students to definitions, history, purposes and the relationships of limnology with other disciplines. It discusses water and environment; features of inland water ecosystems (lotic and lentic systems) and freshwater biotic communities. It also examines impoundments (purposes, consequences, etc.), sustainable management of impounded water systems and pollution of freshwater systems will also be discussed.
This course introduces students to the basic anatomy and fundamental mechanisms involved in mammalian physiological functions. It includes a study of the structure and function of the organ systems involved in digestion, transport, respiration, co-ordination, excretion, reproduction, support and locomotion. Principles of homeostasis will be emphasized.
This course reviews the taxonomy, functional anatomy and biology of the protochordates, cyclostomes, fishes, amphibians, reptiles, birds and mammals. It also reviews the origins of chordates and their evolutionary history and provides a survey of embryonic development in the chordates. The course involves extensive practical work in which live and preserved animals will be used for illustrations.
The first part of the course reviews the diversity of micro-organisms including Viruses Bacteria, Fungi and Protozoa. Their importance in nature and effects on man will be emphasized. The course discusses the uses of microbes – both beneficial and adverse. The second part of the course examines heterospecific associations with special emphasis on parasitism. The life cycles and control measures against some common parasites will be discussed e.g. Plasmodium, Trypanosoma, Schistosoma, Fasciola, Ascaris, Onchocerca and Dracunculus.
Students are introduced to Polygenes and the Hardy-Weinberg law. The latter is illustrated by sickle cell anaemia, melanism in moths, drug resistance, insecticide resistance and mimicry in butterflies. The course also examines the concept of evolution and the distribution of organisms in time and space. It also reviews the theories of evolution, natural selection and evidence of evolutionary processes: fossils, geographical distribution, comparative anatomy, vestigial structures, molecular biology and embryology. The origin of Man and the future of Man on earth are also discussed.
The course examines environmental factors and their effects on the distribution and abundance of organisms. It discusses the structure and dynamic aspects of populations; population interactions and regulatory mechanisms; concepts of community and the ecosystem; energy flow in ecosystems; trophic levels, and human ecology. Field studies will include determination of population density, species diversity, evenness and richness and patterns of distribution. These will be related to environmental conditions.
This course uses selected examples of algae, fungi, bryophytes and pteridophytes to illustrate the wide variation in the general features, structure and life histories of cryptogams. The evolutionary trends within and between groups are also discussed.
The course is designed to introduce students to the concept and levels of biological diversity: genetic, species and ecosystem diversity. The threats to global biodiversity and conservation strategies will be discussed. The course also introduces students to the principles and laws of Systematics. Some methods and practical approaches in Taxonomy will also be emphasised e.g. morphometry, the use of keys and isozyme analysis.
The course introduces students to the principles of Systematic Zoology. The laws of Zoological Nomenclature and the procedure for naming animals are discussed. The course also provides a survey of invertebrates and vertebrates emphasizing their phylogenetic relationships. Both preserved and live specimens will be used in practical studies to illustrate the relationships among animals.
This practical course will introduce students to be the knowledge and understanding of basic practical experimental procedures of Organic Chemistry. Students will learn on the scientific skills development such as Observation, Recording, Measurement and Laboratory Reporting Writing. Students will be exposed to how to use equipment’s like the Melting point apparatus, Refractometer, Suction filtration apparatus and Distillation apparatus.
