- New research shows that seagrass has an incredible ability to spread over vast distances of the ocean, which gives them an ability to migrate with climate change and be able to recover from habitat disturbance. The scientists found that seagrass fruit and flowers spread by hitching rides on ocean animals, in animal feces, and in ocean currents. Phys.org

Imagine a healthy, beautiful ocean. Now remove the sea turtles, one by one.
Not so healthy anymore, is it?
That’s the gist of the report we released today, Why Healthy Oceans Need Sea Turtles: The Importance of Sea Turtles to Marine Ecosystems. The report describes the vital roles sea turtles play in the ecosystem, and how the Gulf of Mexico oil spill is further threatening their ability to fulfill those roles.
As the report outlines, sea turtles provide the following important ecosystem services:
- Maintain healthy seagrass beds through grazing
- Maintain healthy coral reefs by removing sponges when foraging
- Facilitate nutrient cycling by supplying a concentrated source of high-protein nutrients when nesting
- Balance marine food webs by maintaining jellyfish populations
- Provide a food source for fish by carrying around barnacles, algae and other similar organisms
- Increase the rate of nutrient recycling on the ocean floor by breaking up shells while foraging
- Provide habitat for small marine organisms as well as offer an oasis for fish and seabirds in the open ocean
