1.   He has joined the tiger project in hopes of raising a better shield for tigers and for their entire rare ecosystem.

2.   In both cases, not just a single species but an entire ecosystem could come under protection, potentially helping hundreds of plants and animals avoid eventual demise.

3.   Low flows in the Colorado River, for example, have destroyed entire ecosystems because so little water from the Colorado actually reaches the Gulf of California.

4.   Not only do giant trawlers haul away the bottom-dwelling fish they seek, such as shellfish or flounder, they often wipe out entire ecosystems.

5.   Scientists say that the entire ecosystem, starting with the lowliest planktons in the sea, has been poisoned.

6.   Sick coral also provides an early warning that entire ecosystems are in danger, according to the researchers.

7.   That raises concerns about their effect on the entire ecosystem, said Andy Scott, research director at Rio Farms, a private agricultural research foundation.

8.   Taking entire ecosystems with their full, diverse panoply of species, rather than just individual species, as the main focus of conservation efforts.

9.   The ocean conditions change the abundance, array and location of sea creatures, which, in turn, affect the entire ecosystem, scientists say.

10.   The researchers suggest sick coral might be a good early warning signal for creeping damage to entire marine ecosystems, which can be hard to detect.
