Claim: Within a decade, certain kinds of branching and plate coral could be extinct, reef scientists say, along with a variety of small fish that rely on them for protection from predators.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: In turn, they are preyed on by larger predatory fish, seabirds and marine mammals.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: This level of variety in the environment benefits many coral reef animals, which, for example, may feed in the sea grass and use the reefs for protection or breeding.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Swordfish are teleosts Rose fish are also teleosts Eels are teleosts too So are seahorses Some of the shortest-lived species are gobies, which are small coral reef–dwelling fish.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: Endangered species - An endangered species is a population of an organism which is at risk of becoming extinct.

Relevance (1 = gold evidence, 0 = mined hard negative): 1
Passage: They are important apex predators feeding on a wide variety of smaller fish and cephalopods.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: For example, coral reefs – which are biodiversity hotspots – will be lost within the century if global warming continues at the current rate.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Increasing sea temperatures in tropical regions (~1 degree C) the last century have caused major coral bleaching, death, and therefore shrinking coral populations since although they are able to adapt and acclimate, it is uncertain if this evolutionary process will happen quickly enough to prevent major reduction of their numbers.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Several fish species have been driven to the edge of extinction and some, such as the disturbed Tokios coral reef formations in the Indian Ocean, are effectively lost.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: The loss of coral reefs, which are predicted to go extinct in the next century, threatens the balance of global biodiversity, will have huge economic impacts, and endangers food security for hundreds of millions of people.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Under increased carbon dioxide concentration expected in the 21st century, corals are expected to becoming increasingly rare on reef systems.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Since countless sea life depend on the reefs for shelter and protection from predators, the extinction of the reefs would ultimately create a domino effect that would trickle down to the many human societies that depend on those fish for food and livelihood.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: Coral reef systems have been in decline worldwide.

Relevance (1 = gold evidence, 0 = mined hard negative): 0
Passage: An overall analysis of coral loss found that coral populations on the Great Barrier Reef had declined by 50.7% from 1985 to 2012, but with only about 10% of that decline attributable to bleaching, and the remaining 90% caused about equally by tropical cyclones and by predation by crown-of-thorns starfishes.
