Create a complete, professional presentation on the topic "Aquatic Ecology: Freshwater and Marine, from a Landscape Architecture Perspective". It is a group topic presentation for a Master of Landscape Architecture class, so the tone should be academic but clear, and every section should connect ecology to design decisions. Cover these topics in this order: 1. Introduction and importance - Definition of aquatic ecology, the water cycle, freshwater vs marine systems - Ecosystem services: water purification, flood control, microclimate, biodiversity, recreation - Why it matters to landscape architects, with water as a design driver 2. Freshwater ecosystems - Lentic systems (lakes, ponds, wetlands) and lotic systems (rivers, streams) - Zonation: littoral, limnetic, profundal - Riparian zones, floodplains, and typical flora and fauna 3. Marine and coastal ecosystems - Oceans, estuaries, mangroves, salt marshes, coral reefs, seagrass, dunes - Intertidal zones and salinity gradients - Typical flora and fauna 4. Ecological components and processes - Abiotic factors: light, temperature, dissolved oxygen, pH, salinity, nutrients - Biotic components and the aquatic food web - Nutrient cycling and eutrophication 5. Threats and degradation - Pollution, urban runoff, encroachment, wetland loss - Invasive species such as water hyacinth - Sea-level rise, coastal erosion, climate change 6. Landscape architecture strategies for freshwater - Constructed wetlands, bioswales, rain gardens, SuDS - Riparian buffers, river and lake edge restoration - Phytoremediation and aquatic planting zones (emergent, floating, submerged) 7. Landscape architecture strategies for marine and coastal areas - Living shorelines, mangrove and dune restoration - Coastal buffers and setbacks - Designing for tides, storm surge and salinity 8. Case studies, policy and conclusion - Case studies: Cheonggyecheon (Seoul), Bishan-Ang Mo Kio Park (Singapore), Sabarmati Riverfront (Ahmedabad), Yamuna floodplain (Delhi), each with one clear design lesson - Policy: Ramsar Convention, Wetland Rules 2017, CRZ Notification - Key takeaways and design principles Include these visual elements: - Labelled section diagrams: lake zonation, estuary, mangrove profile - A comparison table of freshwater vs marine ecosystems - Plant palette tables for aquatic planting zones - Before and after images for the case studies - A references slide at the end
