Habitats
- When Flowering Plants Re-Made The World
- "The flowers' secret
was to exploit a change in soil fertility, and create a feedback loop that allowed new flowers to feed off dead ones."
- Desperate Measures To Save Wetlands
- "The most effective tool for cleaning up the oil working its way into southern Louisiana wetlands may, in the end, be the equivalent of a box of kitchen matches."
- Even Biofuel Production Threatens Wetlands
- "If we don't plan and invest properly now, the cost to recreate artificially the services wetlands provide will dwarf the cost of preserving and protecting them in the first place."
- Why The Pieces Can't Be Put Back
- "A seven-year experiment shows that pond communities bear the imprint of random events in their past, such as the order in which species were introduced into the ponds. This finding locates one of the wellsprings of biodiversity but also suggests that it may not be possible to restore ecosystems whose history we cannot recreate."
- A Symbiotic Relationship That Moves Mountains
- "Few plants can grow without soil and even fewer are capable of growing on nothing but bare rock.Yet some species of desert cactus manage this extraordinary feat, and now scientists have worked out how."
