1Patterns of Marine Biodiversity:
Highest diversity habitats are:
• Coral reefs
• Estuaries
• Deep-ocean floor
• Coastal diversity > Open sea
• Benthic (bottom) diversity > Pelagic (surface)
• Lowest diversity in the mid-depth open ocean
2Strategies to Protect North American Coastal Waters
• Comprehensive legislation
• Federal funding
• Focus fisheries management on whole ecosystems and habitats
• Establish marine network linked by corridors
3Human Impacts on Aquatic Biodiversity
- Commercial fishing
- Non-native species (intentionally intruduced or accidentially from balast water)
4Protecting and Sustaining Marine Biodiversity
challenges
Challenges
• Rapid coastal
development
• Damage not visible
• International waters
under no single
jurisdiction
5Endangered Sea Turtles: why are they endangered
• Loss of beach habitat where eggs laid
• Human removal of eggs
• Use of turtles for food, medicine, clothing
• Bycatching
