Dr. I. Sware.Semesi
\r\nTeaches undergraduate courses in the field aquatic ecology.

\r\n\r\nUndergraduate courses:
\r\nAQ 211 Mangrove and Seagrass Ecosystems 2 Units: Taught during 1st Semester
\r\nAQ 321 Ecology of Coral Reefs 2 Units: Taught during 2nd Semester

AQ 211 Mangrove and Seagrass Ecosystems (2 units)\r\n\r\nObjectives:
To introduce students to the mangrove and seagrass ecosystems with respect to their systematics and ecology. This knowledge is fundamental to the conservation and management of these important ecosystems.

\r\n(i) Characterization of mangroves and their adaptations, taxonomy and evolution, physiographic features favouring mangroves, reproductive strategies. Zonation in mangrove forests. The biota of mangrove communities and their ecology. Ecological and socio-economic roles of mangrove ecosystems. Mangroves in Tanzania: species, distribution, utilization, degradation, management and restoration.

\r\n(ii) Seagrass systematics, habitats, adaptations, and reproduction. The biota of seagrass beds, ecology, and zonation. Seagrasses in Tanzania: species, distribution, and degradation. Ecological and economic roles of seagrass beds. Management of seagrass ecosystems. Interactions between mangrove, seagrass, and coral reef ecosystems.

\r\n(iii) Sampling techniques in mangrove forests and seagrass beds.\r\n

\r\nDelivery: 15 lecture hours and 45 practical classes. \r\n

\r\nAssessment: Essay and tests 15%; mid-semester examination 25%; final examination 60%
