HWST 155: Nā Limu Hawaiʻi: Hawaiian Seaweeds and their Uses
An introduction to Hawaiian Limu biology, ecology, and diversity. Students will learn about the historical, current, and potential uses of Limu and choose a species to research. An introduction to Limu groups (red, green and brown) and sustainable cultivation. Students will learn about the cultural significance and history of Limu in Hawai’i.
Course Outcomes
- Identify and describe the diversity of Hawaiian limu
- Describe the biology and ecology of Hawaiian limu
- Describe the historical and current uses of Hawaiian limu
- Apply knowledge to potential limu cultivation and conservation practices
HWST 155L: Nā Limu Hawaiʻi: Hawaiian Seaweeds and their Uses Lab
Students will study the various morphologies of local limu species and learn basic limu hatchery and farming techniques such as tumble culture or attached cultivation methods. Hands-on experience in the cultivation, and instruction in the equipment necessary to monitor and manage the cultivation system will take place in the hands-on laboratory. Students are introduced to media preparation, sterile technique, various Limu cultivation methods, and stereomicroscopy. Students will learn seeding techniques for re-planting Limu in critical habitats. Additionally, some lab skills such as DNA extraction/sequencing, and lipid extractions will be covered.
Prerequisites
Completed or concurrently enrolled in HWST 155.
Course Outcomes
- Identify Hawaiian Limu through keying out species based on morphology
- Demonstrate the use of basic lab equipment to analyze culture systems such as stereomicroscopy and biomass measurements
- Use DNA sequencing to definitively identify Limu
- Apply knowledge to potential limu cultivation and conservation practices in hands on experiential learning.
